laravel-repository — Автоматическая генерация типобезопасных репозиториев для Laravel

--- name: laravel-repository description: > Generate production-ready Laravel repository classes for Eloquent models following strict architectural conventions. Each repository is tightly coupled to a specific model class (e.g., UserRepository → User model, PostRepository → Post model). Use this skill whenever the user asks to create, scaffold, generate, or write a Laravel repository, data access layer, or model repository class. Also trigger when the user says things like "make me a repository for X", "create a repository class for User", "create a repository for the Post model", "I need a repository to handle Z queries", or "add a repository for X". Always use this skill for Laravel repository generation — do not improvise the structure without consulting this skill first. --- # Laravel Repository Skill Generate clean, type-safe Laravel repository classes that encapsulate write and state-change operations for a given model, following strict conventions. --- ## Conventions (Non-Negotiable) 1. **Namespace** — always `AppRepositories`; class named `{ModelName}Repository`. 2. **No constructor, no class properties** — repositories are stateless. Every method receives what it needs via parameters. 3. **Full type hints** — every parameter AND return type must be declared. No untyped parameters, no missing return types. 4. **No array parameters** — method parameters must be individual, named, typed scalars/objects. The only exception is a field whose database column stores an array/JSON value (e.g., `array $tags`). 5. **Write methods only** — do not generate any read/select/query methods (`find`, `get`, `all`, `paginate`, `where`, etc.). Repositories only contain `create`, `update`, `delete`, and single-field state methods. 6. **Field-by-field assignment** — never use mass assignment (`create([...])` / `fill([...])`). Assign each field on its own line, then call `$model->save()`. 7. **Slug & identifier fields** — use `ModelManager` methods. **You do not know the exact signatures — read the `ModelManager` class before calling them.** - `(new ModelManager)->generateUniqueSlug(...)` — for slug fields - `(new ModelManager)->generateUniqueIdentifier(...)` — for unique code/identifier fields 8. **Return types for mutating methods**: - `create()` / `update()` → return the model instance: `{ModelName}` - `delete()` / `destroy()` → `bool` - Single-field toggles (`toggleActive()`, `setStatus()`, `markActive()`, etc.) → `void` 9. **Import every dependency** — all classes referenced in the file must appear as `use` statements. 10. **`final` class** — repositories are not meant to be extended. 11. **Docblocks on every method** — every public method must have a PHPDoc block describing its purpose, `@param` for each parameter, and `@return` for the return type. 12. **Foreign ID fields use model objects** — when a field is a foreign key (e.g., `user_id`, `category_id`, `post_id`), the method parameter must be the related model object (e.g., `User $user`), not a scalar ID. Assign with `$model->user_id = $user->id;`. Import the related model class. --- ## File Location ``` app/Repositories/{ModelName}Repository.php ``` --- ## Class Template ```php <?php namespace AppRepositories; use AppModels{ModelName}; use AppModelsUser; use AppManagersModelManager; final class {ModelName}Repository { /** * Create a new {ModelName} record. * * @param string $title * @param string $body * @param User $user * @return {ModelName} */ public function create( string $title, string $body, User $user, // …one parameter per field ): {ModelName} { $model = new {ModelName}(); $model->title = $title; $model->slug = (new ModelManager)->generateUniqueSlug(/* read ModelManager for params */); $model->body = $body; $model->user_id = $user->id; // …assign each remaining field $model->save(); return $model; } /** * Update an existing {ModelName} record. * * @param {ModelName} $model * @param string $title * @param string $body * @param User $user * @return {ModelName} */ public function update( {ModelName} $model, string $title, string $body, User $user, // …one parameter per field ): {ModelName} { $model->title = $title; $model->slug = (new ModelManager)->generateUniqueSlug(/* read ModelManager for params */); $model->body = $body; $model->user_id = $user->id; // …assign each remaining field $model->save(); return $model; } /** * Delete a {ModelName} record. * * @param {ModelName} $model * @return bool */ public function delete({ModelName} $model): bool { return (bool) $model->delete(); } /** * Toggle the active state of a {ModelName}. * * @param {ModelName} $model * @return void */ public function toggleActive({ModelName} $model): void { $model->is_active = ! $model->is_active; $model->save(); } /** * Set the status of a {ModelName}. * * @param {ModelName} $model * @param string $status * @return void */ public function setStatus({ModelName} $model, string $status): void { $model->status = $status; $model->save(); } } ``` --- ## Field Assignment Rules ### Standard scalar fields ```php $model->title = $title; $model->description = $description; $model->price = $price; ``` ### Foreign ID fields (use model object — NOT a scalar int) ```php // Parameter: User $user → assigns: $model->user_id = $user->id; // Parameter: Category $category → assigns: $model->category_id = $category->id; $model->user_id = $user->id; $model->category_id = $category->id; ``` ### Slug field ```php // Read the ModelManager class to determine the correct parameters before calling: $model->slug = (new ModelManager)->generateUniqueSlug(/* params from ModelManager */); ``` ### Unique identifier/code field ```php // Read the ModelManager class to determine the correct parameters before calling: $model->identifier = (new ModelManager)->generateUniqueIdentifier(/* params from ModelManager */); ``` ### Array/JSON field (the ONE exception for array parameters) ```php // Only allowed when the column genuinely stores an array/JSON value $model->tags = $tags; ``` --- ## Return Type Quick-Reference | Method type | Return type | |---|---| | `create` | `{ModelName}` | | `update` | `{ModelName}` | | `delete` / `destroy` | `bool` | | `toggleActive`, `setStatus`, `markAs*` | `void` | --- ## Decision Guide | Scenario | Action | |---|---| | Field is a slug | Call `ModelManager->generateUniqueSlug()` — read the class for its parameters | | Field is a unique code/identifier | Call `ModelManager->generateUniqueIdentifier()` — read the class for its parameters | | Field is a foreign key (`*_id`) | Accept the related model object as parameter; assign `$model->field_id = $relatedModel->id;` | | Method only flips one column | Return `void`, not `bool` or model | | Column stores JSON/array data | Array parameter is allowed for that column only | | Soft-delete model | `delete()` returns `bool`; add `restore({ModelName} $model): void` if needed | | User asks for a find/get/search method | Decline — read methods do not belong in the repository | --- ## Complete Example **Request:** "Create a repository for a `Post` model with fields: `title`, `slug`, `body`, `is_active`, `status`, `tags` (JSON array), `user_id`." ```php <?php namespace AppRepositories; use AppManagersModelManager; use AppModelsPost; use AppModelsUser; final class PostRepository { /** * Create a new Post record. * * @param string $title * @param string $body * @param string $status * @param array $tags * @param User $user * @return Post */ public function create( string $title, string $body, string $status, array $tags, User $user, ): Post { $post = new Post(); $post->title = $title; $post->slug = (new ModelManager)->generateUniqueSlug(/* read ModelManager for params */); $post->body = $body; $post->status = $status; $post->tags = $tags; $post->is_active = false; $post->user_id = $user->id; $post->save(); return $post; } /** * Update an existing Post record. * * @param Post $post * @param string $title * @param string $body * @param string $status * @param array $tags * @param User $user * @return Post */ public function update( Post $post, string $title, string $body, string $status, array $tags, User $user, ): Post { $post->title = $title; $post->slug = (new ModelManager)->generateUniqueSlug(/* read ModelManager for params */); $post->body = $body; $post->status = $status; $post->tags = $tags; $post->user_id = $user->id; $post->save(); return $post; } /** * Delete a Post record. * * @param Post $post * @return bool */ public function delete(Post $post): bool { return (bool) $post->delete(); } /** * Toggle the active state of a Post. * * @param Post $post * @return void */ public function toggleActive(Post $post): void { $post->is_active = ! $post->is_active; $post->save(); } /** * Set the status of a Post. * * @param Post $post * @param string $status * @return void */ public function setStatus(Post $post, string $status): void { $post->status = $status; $post->save(); } } ``` --- ## Checklist Before Outputting - [ ] No `declare(strict_types=1)` - [ ] Class is `final` - [ ] No constructor, no class properties - [ ] No read/get/find/select methods included - [ ] Every parameter is typed - [ ] Every method has a declared return type - [ ] Every method has a PHPDoc block with `@param` and `@return` tags - [ ] No array parameters except for genuine JSON/array columns - [ ] Foreign ID fields (`*_id`) accept the related model object, not a scalar int - [ ] Fields assigned one-per-line, not via `create([...])` or `fill([...])` - [ ] `ModelManager` methods used for slug/identifier fields, with parameters sourced from reading the class - [ ] `create()` / `update()` return the model instance - [ ] `delete()` returns `bool` - [ ] Single-field state methods return `void` - [ ] All referenced classes have `use` import statements
