Php 如何使用Laravel获取属于外键的用户名？
我想使用Laravel Eloquent获得外键所属的用户名 我有一个模型：Php 如何使用Laravel获取属于外键的用户名？,php,laravel,laravel-5.3,Php,Laravel,Laravel 5.3,我想使用Laravel Eloquent获得外键所属的用户名 我有一个模型： Class Posts Extends Eloquent{ protected $table = 'posts'; protected $fillable = array('title, image, text, user_id'); public $timestamps = false; } 及 用户模型： class User extends Authenticatable { use Notifiab
Class Posts Extends Eloquent{
protected $table = 'posts';
protected $fillable = array('title, image, text, user_id');
public $timestamps = false;
}
class User extends Authenticatable
{
use Notifiable;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'name', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
}
public function index(){
// get all the bears
$posts = Posts::all();
return View::make('welcome', compact('posts'));
}
要设置用户->帖子的关系，可以使用
hasManypublic function posts(){
return $this->hasMany('App\Post');
}
用户idpublic function posts(){
return $this->hasMany('App\Post', name_of_column_in_post_table, name_of_column_in_user_table);
}
hasOnebelongsTopublic function users() {
return $this->belongsTo('App\User', name_of_column_in_user_table, name_of_column_in_post_table);
}
然后，您可以通过在模型类中执行
$post->user->nameClass Posts Extends Eloquent{
protected $table = 'posts';
protected $fillable = array('title, image, text, user_id');
public $timestamps = false;
public function user()
{
return $this->belongsTo('App\User','user_id);
}
}
$post->user
阅读有关多对一关系甚至是即时加载的文档。将模型之间的一对多关系定义为：
class Posts extends Model
{
public function user(){
return $this->belongsTo('App\User');
}
// Whatever your code in Post model
}
class User extends Model
{
public function posts(){
return $this->hasMany('App\Post');
}
// Whatever your code in User model
}
Route::get('/all-posts','PostController@getAllPosts')->name('get_all_posts');
class PostController extends Controller
{
public function getAllPosts() {
$posts = Posts::all();
foreach ($posts as $post){
$username = $post->user->name;
//do something with $username
}
return view('all_posts')->with('detailed_posts');
//here the $detailed_posts can be defined in the 'do something' above
}
}
class PostController extends Controller
{
public function getAllPosts() {
return view(all_posts);
}
}
<html>
<div>
<h1>All Posts</h1>
@foreach (App\Post::all() as $post)
<span> Title : {{ $post->title}}</span>
<span> Username: {{$post->user->name}}</span>
.......
@endforeach
</div>
</html>
所有职位
@foreach（App\Post:：all（）作为$Post）
标题：{{$post->Title}
用户名：{{$post->user->name}
