A reusable quiz plugin for SummerCMS applications: quizzes with single-choice, multiple-choice and self-check (flashcard) questions, a learning and a test mode that withholds solutions until an attempt is finished, scored attempts for signed-in users, an admin backend, a JSON importer and owner management over a token API and MCP tools.

import _ "git.golem15.com/golem15/sm-quizzes-plugin"

Module git.golem15.com/golem15/sm-quizzes-plugin, package quizzes, plugin ID golem15.quizzes.

Overview

The plugin is a compiled SummerCMS plugin. Its init registers it with the framework, so an application loads it by listing it in summer.yaml; summer build then emits the blank import above into the application's plugins.gen.go. It requires golem15.user: the API runs behind that plugin's jwt.auth middleware, and attempts reference its users table.

The plugin knows nothing about the application around it. A quiz links to a record of another plugin through an optional free-form context string, such as acme.courses:course:12; clients list the quizzes of a context with GET /quizzes?context=....

It owns five tables:

Table	Holds
`golem15_quizzes_quizzes`	Quizzes: title, unique slug, description, context, published flag, time limit, passing score, question shuffling, round size, and the test settings `mode`, `navigation` and `max_attempts`.
`golem15_quizzes_questions`	Questions of a quiz: text, type, category, model answer, explanation, sort order and points.
`golem15_quizzes_answers`	Answers of a single or multiple question, with `is_correct` and an explanation.
`golem15_quizzes_attempts`	One user's run through a quiz, or through one category of it, with the score once finished.
`golem15_quizzes_attempt_answers`	The user's answer to one question of an attempt; one row per attempt and question.

Deleting a quiz deletes its questions, answers and attempts. Deleting a question deletes its answers and the attempt answers given to it. Deleting a user deletes their attempts.

Features

Three question types. single (one correct answer), multiple (one or more correct answers) and self_check, a flashcard: the client shows the question, the user reveals answer_text and marks themselves as knowing it or not.
Categories. A question may carry a category. GET /quizzes/{slug}?category= returns one category, and an attempt can be limited to one category.
Rounds and shuffling. round_size tells the client to present the questions in rounds of N; shuffle_questions shuffles the question order on every GET /quizzes/{slug}.
Attempts. A user starts an attempt, answers questions in any order (answering again overwrites the earlier answer and returns fresh feedback) and finishes it. Answers are refused after the time limit; finishing is still allowed and counts the answers given in time.
Scoring. A pure function in classes (classes.Score, classes.Totals) with optional partial credit for multiple questions and an optional penalty for wrong answers. See Configuration.
No solution leaks. The quiz payload never contains is_correct or explanations, and answer_text only for self_check flashcards, which have nothing to hide. Feedback reveals the solution of the question just answered; a result reveals the solutions of answered questions, and of every question once the attempt is finished.
Test mode. A quiz set to test withholds every solution until the attempt is finished, and the server enforces the attempt limit, the time limit and one-way navigation. See Test mode.
Admin backend. Quizzes, Questions (filtered by quiz, category and type) and Answers (filtered by quiz) under the golem15.quizzes.access_quizzes permission, and a read-only Attempts list under golem15.quizzes.access_attempts. Polish and English labels.
Importer. quizzes:import loads a quiz from a JSON file, idempotent by slug. See CLI commands.

Test mode

A quiz has a mode: learning (the default; every existing quiz) or test. Learning quizzes behave exactly as before test mode existed. Two more settings only apply to tests: navigation (free, the default, or one_way) and max_attempts (null for unlimited).

Withholding. While a test attempt is open, no student response carries a solution: the answer feedback has withheld: true and null for is_correct, points, correct_answer_ids, explanation and answer_text; the result has solutions_withheld: true and null for is_correct, points_earned, correct_answer_ids, explanation and answer_text on every question, answered or not, and no answer carries is_correct or explanation. The student's own input (answered, answer_ids, known) stays. GET /quizzes/{slug} of a test lists no questions (questions: [], question_count counts them), so a timed test cannot be read before its clock starts; the test player reads the questions from GET /attempts/{id}.
Full review after finish. Once completed_at is set (finish, or a lazy close) the result reveals everything, exactly as for a finished learning attempt, with passed against passing_score.
Attempt limit. max_attempts counts every attempt of the user on the quiz, open or finished, in any mode. A start past the limit is a 409 with code: attempt_limit_reached. Learning quizzes have no limit.
Resume. Starting a test while an open, unexpired attempt exists returns that attempt (200, resumed: true) instead of creating one, so a page reload does not burn an attempt. Starts are serialised per quiz and user with a Postgres advisory lock (pg_advisory_xact_lock), so parallel starts cannot exceed the limit.
Time limit and grace. An answer to a test is refused (409, code: time_limit_exceeded) after started_at + time_limit_seconds plus a grace for answers still in flight, golem15.quizzes.test.grace_seconds (default 5). Learning quizzes have no grace. Finishing stays allowed after the deadline; unanswered questions score 0. seconds_left on every attempt row is counted by the server.
Lazy close. A test attempt past its deadline and grace is closed on the next start of that quiz or the next GET /attempts/{id}: completed_at is set to its deadline and it is scored with the answers given in time, as a finish would. No job queue is involved.
Whole quiz only. A test always covers every question: starting one with a category is a 422 on category (category_not_allowed), and GET /quizzes/{slug} of a test ignores ?category=.
Stable order. With shuffle_questions, a test attempt's questions come in an order seeded by the attempt, the same on every GET /attempts/{id} and on finish.
One-way lock. With navigation: one_way an answer is final: a second answer to the same question is a 409 with code: answer_locked and the stored answer is unchanged. With free an answer is overwritten until the attempt is finished.

Usage

Mount the plugin in an application as a git submodule at plugins/golem15/quizzes, next to plugins/golem15/user, add it to the application's go.work, require it in the application's go.mod with a local replace, and list it in summer.yaml after golem15.user:

plugins:
  - id: golem15.user
    module: git.golem15.com/golem15/sm-user-plugin
  - id: golem15.quizzes
    module: git.golem15.com/golem15/sm-quizzes-plugin

The plugin's own go.mod replaces the framework with ../../../../summercms.go and golem15.user with ../user, so it expects the framework checkout next to the application checkout.

Run migrate after summer build to create the tables, then import a quiz and publish it in the admin (or set "is_published": true in the file).

API reference

All routes are mounted under /_quizzes/api/v1 with the jwt.auth middleware of golem15.user: send Authorization: Bearer <token>. A missing or invalid token is a 401 from the guard. Every successful body wraps its payload in data. Timestamps are UTC in the form 2026-10-02T12:00:00+00:00.

Method and path	Handler	Does
`GET /quizzes`	`api.Handlers.ListQuizzes`	Published quizzes, by title, with the caller's statistics. Query: `context`.
`GET /quizzes/{slug}`	`api.Handlers.ShowQuiz`	A published quiz with its questions and answers, without solutions (a `self_check` question carries its `answer_text`); a test lists no questions. Query: `category`.
`POST /quizzes/{slug}/attempts`	`api.Handlers.StartAttempt`	Starts an attempt, or resumes an open test attempt. Body (optional): `{"category": "..."}`.
`POST /attempts/{id}/answers`	`api.Handlers.Answer`	Saves or overwrites the answer to one question and returns feedback.
`POST /attempts/{id}/finish`	`api.Handlers.Finish`	Finishes the attempt and returns the result.
`GET /attempts/{id}`	`api.Handlers.ShowAttempt`	The result with per-question details.
`GET /attempts`	`api.Handlers.ListAttempts`	The caller's attempts, newest first. Query: `quiz` (slug), `page`, `per_page` (default 20, at most 100).

{slug} matches [a-z0-9-]+ and {id} matches [0-9]+; anything else is a 404.

Errors

Status	Body	When
401	`{"error": true, "message": "Token not provided"}`	No or invalid token (from the guard).
404	`{"error": "Quiz not found"}`	Unknown or unpublished slug.
404	`{"error": "Attempt not found"}`	Unknown attempt, or another user's attempt.
409	`{"error": "The attempt is already completed.", "code": "attempt_completed"}`	Answering or finishing a finished attempt.
409	`{"error": "The time limit of this attempt has been exceeded.", "code": "time_limit_exceeded"}`	Answering after `started_at + time_limit_seconds` (plus the grace of a test).
409	`{"error": "All attempts at this test have been used.", "code": "attempt_limit_reached"}`	Starting a test after `max_attempts` attempts.
409	`{"error": "An answer in this test cannot be changed.", "code": "answer_locked"}`	Answering a question of a `one_way` test again.
413	`{"error": "Payload too large"}`	A body over the route's limit.
422	`{"error": "<first message>", "errors": {"<field>": ["<message>"]}}`	Invalid input, the shape `golem15.user` uses. Keys follow the rule order. Starting a test with a category is a 422 on `category`: "A test covers the whole quiz; a category cannot be chosen."

Every 409 body carries code, a stable key clients can branch on; the error message is for people. The messages are translated into the request locale (golem15.quizzes::lang.api.*, Polish and English).

GET /quizzes

{"data": [{
  "id": 1,
  "slug": "security-basics",
  "title": "Security basics",
  "description": "Flashcards and checks.",
  "context": "acme.courses:course:12",
  "question_count": 54,
  "time_limit_seconds": null,
  "passing_score": 50,
  "round_size": 5,
  "shuffle_questions": false,
  "best_score_percent": 83.33,
  "attempts_count": 2,
  "mode": "test",
  "navigation": "free",
  "max_attempts": 3,
  "attempts_left": 1,
  "question_types": {"single": 20, "multiple": 10, "self_check": 24}
}]}

attempts_count counts the caller's finished attempts and best_score_percent is their best finished result (null before the first one). question_types counts the questions per type, with all three keys always present. attempts_left is how many attempts the caller may still start at a test with a limit (every attempt counts, open or finished); it is null for a learning quiz or a test without a limit.

GET /quizzes/{slug}

{"data": {
  "id": 1, "slug": "security-basics", "title": "Security basics", "description": null,
  "context": "acme.courses:course:12", "time_limit_seconds": null, "passing_score": 50,
  "round_size": 5, "shuffle_questions": false,
  "question_count": 2,
  "categories": ["Documents", "Theory"],
  "mode": "learning", "navigation": "free", "max_attempts": null, "attempts_left": null,
  "questions": [
    {"id": 10, "text": "What is societal resilience?", "type": "self_check", "category": "Theory",
     "points": 1, "sort_order": 1, "answer_text": "The ability of a society to withstand a crisis.", "answers": []},
    {"id": 11, "text": "Which is a strategy document?", "type": "single", "category": "Documents",
     "points": 1, "sort_order": 2, "answers": [{"id": 30, "text": "National Security Strategy"}, {"id": 31, "text": "Highway Code"}]}
  ]
}}

categories lists every category of the quiz; with ?category= the questions are only that category's and question_count counts them. Questions come in sort_order, or shuffled when shuffle_questions is true. Answers come in their sort order. For a test, questions is empty, question_count counts the whole quiz, ?category= is ignored and attempts_left is set as in the list.

POST /quizzes/{slug}/attempts

Body, optional: {"category": "Theory"} limits the attempt to one category; a category without questions is a 422 on category, and a test refuses any category. Answers status 201 with a new attempt, or 200 when an open test attempt is resumed:

{"data": {
  "id": 7, "quiz_id": 1, "quiz_slug": "security-basics", "quiz_title": "Security basics",
  "category": null,
  "started_at": "2026-10-02T12:00:00+00:00",
  "expires_at": null,
  "completed_at": null,
  "answered_count": 0,
  "score_points": 0, "max_points": 54, "score_percent": null,
  "passing_score": 50, "passed": null,
  "quiz_mode": "learning", "quiz_navigation": "free", "seconds_left": null,
  "resumed": false, "attempts_left": null
}}

expires_at is started_at + time_limit_seconds, or null without a limit. seconds_left is the whole seconds until expires_at, rounded up and never below 0, counted by the server; it is null without a limit and once the attempt is finished. quiz_mode and quiz_navigation tell the player which flow to run. max_points sums the points of the questions the attempt covers. This attempt shape, without resumed and attempts_left, is also each row of GET /attempts and the head of a result. resumed is true when an open test attempt was returned; attempts_left counts the attempts left after this one (null for a learning quiz or without a limit).

POST /attempts/{id}/answers

Body:

Field	Rules
`question_id`	Required integer; the question must belong to the attempt's quiz (and category).
`answer_ids`	Array of answer IDs. Required for `single` (exactly one) and `multiple`; every ID must belong to the question.
`known`	Boolean. Required for `self_check`.

Checks run in this order: the body (422), the attempt belongs to the caller (404), it is not finished (409), it is within the time limit plus the grace of a test (409), the question belongs to it (422 on question_id), a one_way test has no answer to it yet (409), the answer fits the question (422 on answer_ids or known). Answering a question again overwrites the stored answer. Answers status 200:

{"data": {
  "question_id": 11,
  "withheld": false,
  "is_correct": false,
  "points": 0,
  "correct_answer_ids": [30],
  "explanation": "A strategy sets goals and the ways to reach them.",
  "answer_text": null,
  "answers": [
    {"id": 30, "text": "National Security Strategy", "is_correct": true, "explanation": null},
    {"id": 31, "text": "Highway Code", "is_correct": false, "explanation": "A traffic law."}
  ]
}}

points can be negative when scoring.penalty_wrong is set. For a self_check question correct_answer_ids and answers are empty and answer_text holds the model answer. For an open test attempt withheld is true and is_correct, points, correct_answer_ids, explanation and answer_text are null; the answers carry only id and text (is_correct and explanation null).

POST /attempts/{id}/finish and GET /attempts/{id}

Finishing sums the stored points, floors the total at 0, sets score_percent = score_points / max_points * 100 (two decimals) and completed_at. Finishing a finished attempt is a 409. Both routes answer the attempt shape plus questions:

{"data": {
  "id": 7, "quiz_id": 1, "quiz_slug": "security-basics", "quiz_title": "Security basics", "category": null,
  "started_at": "2026-10-02T12:00:00+00:00", "expires_at": null, "completed_at": "2026-10-02T12:09:41+00:00",
  "answered_count": 2, "score_points": 1, "max_points": 2, "score_percent": 50,
  "passing_score": 50, "passed": true,
  "quiz_mode": "learning", "quiz_navigation": "free", "seconds_left": null,
  "solutions_withheld": false,
  "questions": [
    {"id": 10, "text": "What is societal resilience?", "type": "self_check", "category": "Theory", "points": 1,
     "answered": true, "answer_ids": [], "known": true, "is_correct": true, "points_earned": 1,
     "correct_answer_ids": [], "explanation": null, "answer_text": "The ability to withstand a crisis...", "answers": []},
    {"id": 11, "text": "Which is a strategy document?", "type": "single", "category": "Documents", "points": 1,
     "answered": true, "answer_ids": [31], "known": null, "is_correct": false, "points_earned": 0,
     "correct_answer_ids": [30], "explanation": "A strategy sets goals...", "answer_text": null,
     "answers": [{"id": 30, "text": "National Security Strategy", "is_correct": true, "explanation": null},
                 {"id": 31, "text": "Highway Code", "is_correct": false, "explanation": "A traffic law."}]}
  ]
}}

passed is score_percent >= passing_score once the attempt is finished, else null. While the attempt is open, an unanswered question has correct_answer_ids, explanation and answer_text set to null and is_correct/explanation of its answers set to null; its own is_correct is false and points_earned 0. While a test attempt is open solutions_withheld is true and every question, answered or not, has is_correct, points_earned, correct_answer_ids, explanation and answer_text set to null, with no answer is_correct or explanation; answered, answer_ids and known stay. With shuffle_questions a test attempt lists its questions in an order seeded by the attempt, the same on every call; other attempts list them in sort order.

GET /attempts

Management API and MCP tools

The owner manages quizzes from an MCP client (or any HTTP client) with a golem15.user API token. Every route below runs behind user.api_token, the per-user throttle golem15.quizzes.manage (120 requests a minute), the token scope named in the table and the golem15.quizzes.access_quizzes permission. The plugin declares that permission through pact.HasFrontendPermissions, so it shows up in golem15.user's User Groups editor. Grant it to the owner's group only, because the stats show student emails and names. Declaring it grants nothing. There is no owner column: a holder of the permission manages every quiz, as in the admin. Quizzes are addressed by slug.

Method and path under `/api/v1/quizzes`	Scope	MCP tool	Answer
`GET ""` (`?context=`)	read	`quizzes_list_quizzes`	Every quiz, published or not, ordered by context (none last) and title.
`GET /{slug}`	read	`quizzes_show_quiz`	The quiz with its questions and answers, solutions included.
`POST ""`	write	`quizzes_create_quiz`	201. The new quiz starts unpublished. A taken slug is a 409.
`PATCH /{slug}`	write	`quizzes_update_quiz`	Only sent fields change. `0` clears `time_limit_seconds`, `max_attempts` and `round_size`, and `""` clears `description` and `context`. It cannot publish or change the slug.
`DELETE /{slug}?confirm={slug}`	write	`quizzes_delete_quiz`	`{id, slug, title, questions, attempts}`. A 422 unless `confirm` repeats the slug.
`POST /{slug}/publish`, `POST /{slug}/unpublish`	write	`quizzes_publish`, `quizzes_unpublish`	The quiz. Both are idempotent.
`GET /{slug}/stats`	read	`quizzes_quiz_stats`	`students` and `questions` (see below).
`POST /{slug}/questions`	write	`quizzes_create_question`	201 with the question. It goes last unless `sort_order` is given, and its answers come inline.
`PATCH /{slug}/questions/{id}`	write	`quizzes_update_question`	The question. Only sent fields change. A sent `answers` list keeps and updates the answers with an `id`, creates the ones without and deletes the missing ones.
`DELETE /{slug}/questions/{id}`	write	`quizzes_delete_question`	`{id, quiz_slug}`.
`PUT /{slug}/questions/order`	write	`quizzes_reorder_questions`	The quiz with its questions. `question_ids` must list every question exactly once.
`POST /import?replace=`	write	`quizzes_import_quiz`	The import route (see CLI commands). It has its own `throttle:60,1` and is unchanged.

The quiz shape is id, slug, title, description, context, mode, navigation, max_attempts, time_limit_seconds, passing_score, shuffle_questions, round_size, is_published, question_count, attempts_count, created_at, updated_at. The question shape is id, text, type, category, answer_text, explanation, points, sort_order, answers [{id, text, is_correct, explanation, sort_order}]. These owner shapes are never used by a student route.

Input is checked before the database is read. Invalid JSON, an unknown key or a broken rule is a 422 {"message"}. A merged question must pass the importer's rules (classes.CheckQuestion), and an answer id that belongs to another question is refused. A missing quiz or question is a 404.

History (D-16). A question can be edited while its quiz has attempts. Finished attempts keep their stored scores, and their reviews show the current question. Answers are updated by id and never deleted and recreated, so the answer ids stored in past attempts stay valid. Deleting a question cascades to its answers and to the attempt answers given to it, and an import with replace does the same for every question. On a quiz with attempts, prefer the per-question tools.

Stats. The stats route first closes the quiz's expired open test attempts at their deadline. students [{user_id, email, name, surname, attempts, best_score_percent, last_score_percent, last_completed_at, passed}] counts each student's completed whole-quiz attempts. Learning rounds of one category are left out, and passed is best_score_percent >= passing_score. questions [{id, text, type, answered, correct, correct_percent, most_chosen_wrong}] counts the answers of every completed attempt. correct_percent is null when nobody answered. most_chosen_wrong is {answer_id, text, count}, or null for self_check questions and when no wrong answer was chosen.

Configuration

Defaults live in config/config.yaml and are merged under golem15.quizzes.*.

Key	Default	Meaning
`golem15.quizzes.scoring.multiple_partial`	`false`	Partial credit on `multiple` questions: `(correct chosen - wrong chosen) / correct answers` of the points, floored at 0. Without it only the exact set earns points.
`golem15.quizzes.scoring.penalty_wrong`	`0`	Fraction (0 to 1) of a question's points subtracted for a wrong answer: a non-empty `single` or `multiple` answer that earns nothing. `self_check` answers marked as unknown and empty answers are never penalised. An attempt's total never goes below 0.
`golem15.quizzes.test.grace_seconds`	`5`	Seconds after a test's time limit during which an answer still in flight is accepted, clamped to 0..120. A missing or non-numeric value is 5. Learning quizzes have no grace.

Scores are rounded to two decimals.

The quiz form has three test settings: Mode (Learning / Test), Test navigation (Free / One way) and Attempt limit (empty for none); the last two say in their comments that they apply to tests only. The quiz list shows the mode.

The navigation item is "Quizzes" ("Quizy" in Polish). The admin's relation manager links records through a pivot table only, so questions and answers have their own lists instead of being edited inside the quiz form; filter them by quiz.

CLI commands

Command	Purpose
`quizzes:import <file.json> [--replace]`	Import one quiz from a JSON file.

The same import is served over HTTP as POST /api/v1/quizzes/import (add ?replace=1 for --replace), with the import document as the body. The route runs behind the application-wide API token of golem15.user (user.api_token, created with user:token:create): the token needs the write scope and its user the golem15.quizzes.access_quizzes permission in one of their user groups. It answers {"data": {"id", "slug", "created", "questions", "answers"}}, 422 with a message for a document that does not parse, and 409 for an existing slug without replace. It needs a golem15.user that ships the shared API tokens.

The import runs in one transaction and is idempotent by slug:

a new slug creates the quiz;
an existing slug is refused unless --replace is given;
with --replace the quiz's fields are updated and all its questions are deleted and recreated. The attempts stay, but the attempt answers given to the old questions are deleted with them.

The file is checked before anything is written, and unknown keys are an error. Format:

The SummerCMS framework, git.golem15.com/golem15/summercms (modules backpack, bonfire, bouncer, cabana, lagoon, pact, party, phrasebook, surf, wire).
golem15.user, git.golem15.com/golem15/sm-user-plugin: the jwt.auth middleware and the users table.
gormigrate and GORM, as pinned in go.mod.
testcontainers-go and pgx for the Postgres-backed tests.

Testing

go test -short ./...    # fast run, no Docker
go test ./...           # full run, starts Postgres with testcontainers (needs Docker)

The unit tests cover scoring, request validation, the handlers without a database, the response shapes, the import parser and the admin schema compilation. The Postgres tests run the whole API flow, time limits, cascades, the admin lists and filters and the import command against a throwaway database per test.

Known framework limitations are marked TODO: requires SummerCMS change in the code: admin filter choices read the database through models.FilterDB because pact.FilterOptions receives no context or database; category filter values travel hex-encoded (models.EncodeCategoryValue) because the admin accepts only integer or identifier scope values; and the quiz form cannot embed its questions because the relation manager handles pivot relations only.
