【问题描述】：
我正在尝试了解如何在 Laravel 5.2 中使用“胖模型，瘦控制器”。基本上，我主要了解原因和内容，但不了解如何。我在 Google 上搜索了一段时间，发现有几页描述了为什么（以及一些描述为什么不这样做）和什么，但没有任何页面可以让您轻松理解如何使用瘦控制器创建胖模型。
我创建了一个非常基本的待办事项列表，没有登录或验证，只有最基本的待办事项功能。这个应用程序基本上使用“瘦模型，胖控制器”，我想重写应用程序，以便它使用“胖模型，瘦控制器”。
我在 MySQL 数据库中有三个表：
- 用户
- id int(10)
- uname varchar(255)
- 电子邮件 varchar(255)
- 密码 varchar(60)
- 项目
- id int(10)
- pname varchar(255)
- 注释
- id int(10)
- user_id int(10)
- project_id int(10)
- 内容文本
- time_created 时间戳
- time_deadline 时间戳
- 完成 tinyint(1)
- 删除 tinyint(1)
当我为表创建迁移时，我使用 $table->foreign('user_id')->references('id')->on('users'); 和 $table->foreign('project_id')->references('id')->on('projects'); 来迁移 notes 表。由于某种原因它不起作用，所以在数据库中notes.user_id 和notes.project_id 不是users.id 和projects.id 的外键，这是从一开始的想法。我猜这对我下面的问题并不重要，但如果确实如此，请有人告诉我，以便我尝试解决这个问题。
我有以下模型（已删除文档块）
app\User.php:
<?php
namespace App;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
protected $fillable = [
'name', 'email', 'password',
];
protected $hidden = [
'password', 'remember_token',
];
public function notes()
{
return $this->hasMany(Note::class);
}
}
app\Project.php:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Project extends Model
{
public function notes()
{
return $this->hasMany(Note::class);
}
}
app\Note.php:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Note extends Model
{
public function user()
{
return $this->belongsTo(User::class);
}
public function project()
{
return $this->belongsTo(Project::class);
}
}
我有以下控制器（删除了文档块）
app\Http\Controllers\UserController.php:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
use Response;
class UserController extends Controller
{
public function index()
{
try {
$statusCode = 200;
$users = User::orderBy('uname', 'asc')->get()->toArray();
$response = [];
foreach ($users as $user) {
$this_row = array(
'id' => $user['id'],
'name' => $user['uname'],
);
$response[] = $this_row;
}
} catch (Exception $e) {
$statusCode = 400;
} finally {
return Response::json($response, $statusCode);
}
}
}
app\Http\Controllers\ProjectController.php:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Project;
use Response;
class ProjectController extends Controller
{
public function index()
{
try {
$statusCode = 200;
$projects = Project::orderBy('pname', 'asc')->get()->toArray();
$response = [];
foreach ($projects as $project) {
$this_row = array(
'id' => $project['id'],
'name' => $project['pname'],
);
$response[] = $this_row;
}
} catch (Exception $e) {
$statusCode = 400;
} finally {
return Response::json($response, $statusCode);
}
}
}
app\Http\Controllers\NoteController.php:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Note;
use App\User;
use App\Project;
use Input;
use Response;
use Redirect;
class NoteController extends Controller
{
public function index()
{
try {
$statusCode = 200;
$notes = Note::where('removed', 0)
->orderBy('time_created', 'asc')->get()->toArray();
$response = [];
foreach ($notes as $note) {
$user = User::find($note['user_id']); // Username for note
$project = Project::find($note['project_id']); // Project name
$this_row = array(
'id' => $note['id'],
'user' => $user['uname'],
'project' => $project['pname'],
'content' => $note['content'],
'completed' => $note['completed'],
'created' => $note['time_created'],
'deadline' => $note['time_deadline']
);
$response[] = $this_row;
}
} catch (Exception $e) {
$statusCode = 400;
} finally {
return Response::json($response, $statusCode);
}
}
public function destroy(Request $request)
{
try {
$statusCode = 200;
$note = Note::find($request->id);
$note->removed = 1;
$note->save();
} catch (Exception $e) {
$statusCode = 400;
} finally {
return $statusCode;
}
}
public function edit($request)
{
try {
$statusCode = 200;
$note = Note::find($request);
$response = array(
'id' => $note['id'],
'content' => $note['content'],
'completed' => $note['completed'],
'deadline' => $note['time_deadline']
);
} catch (Exception $e) {
$statusCode = 400;
} finally {
return Response::json($response, $statusCode);
}
}
public function update(Request $request)
{
try {
$statusCode = 200;
$note = Note::find($request->id);
$note->content = $request->content;
$note->time_deadline = $request->deadline;
if ($request->completed == "true") {
$note->completed = 1;
} else {
$note->completed = 0;
}
$note->save();
} catch (Exception $e) {
$statusCode = 400;
} finally {
return $statusCode;
}
}
public function store(Request $request)
{
try {
$statusCode = 200;
$note = new Note;
$note->user_id = $request->user;
$note->project_id = $request->project;
$note->content = $request->content;
$note->time_deadline = $request->deadline;
$note->save();
} catch (Exception $e) {
$statusCode = 400;
} finally {
return $statusCode;
}
}
}
最后，这是我的 app/Http/routes.php (cmets 去掉)
<?php
Route::get('/', function () {
return view('index');
});
Route::get('/notes', 'NoteController@index');
Route::get('/notes/{id}', 'NoteController@edit');
Route::delete('/notes', 'NoteController@destroy');
Route::put('/notes', 'NoteController@store');
Route::post('/notes', 'NoteController@update');
Route::get('/projects', 'ProjectController@index');
Route::get('/users', 'UserController@index');
Route::group(['middleware' => ['web']], function () {
//
});
完整代码可以在我的 GitHub here 找到。
我正在使用 Angular 接收控制器发送的 JSON。这适用于我当前的页面，但如您所见，我的控制器有很多逻辑，我想将其转移到模型中。我不明白我是怎么做到的，所以这是我的问题：
- 我应该创建哪些其他文件？
- 它们应该位于哪里？
- 除了控制器中当前的逻辑之外，我还需要这些文件中的哪些内容？
- 我应该如何重写控制器来处理来自模型的数据？
【问题讨论】：
-
不要将逻辑移到模型中，将其移到存储库和转换器中。控制器调用 Repositories，然后 Repositories 调用 Models，如果需要，Repositories 还将调用 Transformers 来转换所有数据，然后再将其返回给 Controller
