# golem15.journal

The compiled journal plugin for SummerCMS applications: translatable posts and categories, tags, a settings singleton, and the tables a host migrate creates for a blog.

```go
import _ "git.golem15.com/golem15/sm-journal-plugin"
```

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

## 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.translate`. Post and Category store default-locale values on host columns and other locales in `golem15_translate_attributes`. `MorphName` is the PHP class string (`Golem15\Journal\Models\Post`, `Golem15\Journal\Models\Category`); it is never `reflect.Type.String()`.

WinterCMS theme components such as `journalPost` and `journalPosts` are a later successor, not implemented here.

## Features

- **Posts.** `models.Post` maps `golem15_journal_posts`. Translatable fields are title, content, content_html, excerpt, metadata, and slug (indexed). Fillable does not include `redactor_id`, `content_html`, or `user_id`. Attachments `featured_images` and `content_images` use `system_files` under the same MorphName. YAML admin uses `mltext`/`mlmarkdown`. `classes.FormatHTML` regenerates `content_html` on admin save.
- **Categories and tags.** `models.Category` is translatable (name, description, slug). Fillable is name, slug, code, description, parent_id; nest_* columns exist in DDL and are not fillable. `models.Tag` is not translatable. Fillable is name, slug, description. Pivots are `golem15_journal_posts_categories` and `golem15_journal_posts_tags`.
- **Settings.** Singleton row ID=1 on `golem15_journal_settings`, not PHP `system_settings`. `search_use_typesense` defaults to false. A fresh save never contacts Typesense.
- **Public HTTP.** Anonymous GET `/_journal/api/v1/posts`, `/posts/{slug}`, `/categories`, `/tags`, and `/rss`. Writes under the same prefix require a cabana backend JWT (`aud=backend`).
- **Author slug.** Plugin migration adds `backend_users.golem15_bloghub_author_slug`.
- **Import and export.** `journal:export-posts` and `journal:import-posts` write and read one JSON file per post. The Posts list toolbar exposes the same actions to administrators with `golem15.journal.access_import_export`.
- **Phrasebooks.** Embedded `lang/en/lang.yaml` and `lang/pl/lang.yaml` hold plugin, journal, post, category, and tag UI strings. They are independent of model translation JSON.
- **Schema.** Seven gormigrate steps create the six journal tables and the author-slug column. AutoMigrate is not used. Table names are `golem15_journal_*` only.

## Usage

Mount the plugin in an application as a git submodule at `plugins/golem15/journal`:

```sh
git submodule add git@git.golem15.com:golem15/sm-journal-plugin.git plugins/golem15/journal
```

Add it to the application's `go.work`:

```text
use (
	.
	./plugins/golem15/journal
)
```

Require it in the application's `go.mod` with a local replace:

```text
require git.golem15.com/golem15/sm-journal-plugin v0.0.0

replace git.golem15.com/golem15/sm-journal-plugin => ./plugins/golem15/journal
```

List it in `summer.yaml` after translate and run `summer build`:

```yaml
module: git.golem15.com/golem15/acme
binary: acme
plugins:
  - id: golem15.translate
    module: git.golem15.com/golem15/sm-translate-plugin
  - id: golem15.journal
    module: git.golem15.com/golem15/sm-journal-plugin
```

The plugin's own `go.mod` replaces the framework with `../summercms.go` for a sibling checkout next to `summercms.go`. A host application that mounts the plugin at `plugins/golem15/journal` should replace the framework from the host `go.work`.

`Requires()` is exactly `golem15.translate`.

A blog frontend lists published posts and fetches one by slug without a token:

```http
GET /_journal/api/v1/posts
GET /_journal/api/v1/posts/hello-world
GET /_journal/api/v1/categories
GET /_journal/api/v1/tags
GET /_journal/api/v1/rss
```

Editors create a post with a cabana backend JWT (audience `backend`):

```http
POST /_journal/api/v1/posts
Authorization: Bearer <backend-access-token>
Content-Type: application/json

{"title":"Hello","content":"A blog post"}
```

A blog post model already declares translatable fields:

```go
func (Post) Translatable() []string {
	return []string{"title", "content", "content_html", "excerpt", "metadata", "slug"}
}
func (Post) TranslatableIndexes() []string { return []string{"slug"} }
func (Post) MorphName() string             { return `Golem15\Journal\Models\Post` }
```

## CLI commands

Both commands write JSON files (one per post slug), matching the PHP `journal:export-posts` / `journal:import-posts` tools. They are not a CSV ImportExport framework. A blog application binary registers them through `Plugin.Commands`.

| Command | Arguments and flags | Effect |
|---------|---------------------|--------|
| `journal:export-posts` | `--path` (default `journal-export`), `--dry-run` | Writes one JSON file per post, including non-default-locale translations. Attachments are omitted. |
| `journal:import-posts` | `--path` (default `journal-export`), `--force`, `--dry-run` | Creates posts from those files. Existing slugs are skipped unless `--force` updates them. |

```sh
./bin/acme journal:export-posts --path journal-export
./bin/acme journal:import-posts --path journal-export --dry-run
./bin/acme journal:import-posts --path journal-export --force
```

## Dependencies

- SummerCMS modules: backpack, beachcomber, bonfire, cabana, lagoon/attach, pact, party, surf.
- Compiled plugin: `golem15.translate`.
- Third-party: `gorm.io/gorm`, `github.com/go-gormigrate/gormigrate/v2`, `github.com/yuin/goldmark`, `gocloud.dev`. Test-only: `github.com/testcontainers/testcontainers-go`.

## Testing

```sh
go test ./...
```

Postgres integration smokes start Docker unless `-short`. Missing Docker is a failure, not a skip, unless `-short`.
