Laravel 拉雷维尔。在具有关系的模型中使用scope()
我有两个相关的模型:Laravel 拉雷维尔。在具有关系的模型中使用scope(),laravel,laravel-4,eloquent,Laravel,Laravel 4,Eloquent,我有两个相关的模型:Category和Post Post模型有一个published范围(方法scopePublished()) 当我尝试获取该范围内的所有类别时: $categories = Category::with('posts')->published()->get(); 我得到一个错误: 调用未定义的方法published() 类别: class Category extends \Eloquent { public function posts() {
Category
和Post
Post
模型有一个published
范围(方法scopePublished()
)
当我尝试获取该范围内的所有类别时:
$categories = Category::with('posts')->published()->get();
我得到一个错误:
调用未定义的方法published()
类别:
class Category extends \Eloquent
{
public function posts()
{
return $this->HasMany('Post');
}
}
class Post extends \Eloquent
{
public function category()
{
return $this->belongsTo('Category');
}
public function scopePublished($query)
{
return $query->where('published', 1);
}
}
帖子:
class Category extends \Eloquent
{
public function posts()
{
return $this->HasMany('Post');
}
}
class Post extends \Eloquent
{
public function category()
{
return $this->belongsTo('Category');
}
public function scopePublished($query)
{
return $query->where('published', 1);
}
}
您可以在线执行此操作:
$categories = Category::with(['posts' => function ($q) {
$q->published();
}])->get();
您还可以定义一个关系:
public function postsPublished()
{
return $this->hasMany('Post')->published();
// or this way:
// return $this->posts()->published();
}
然后:
//all posts
$category->posts;
// published only
$category->postsPublished;
// eager loading
$categories->with('postsPublished')->get();
顺便说一句,如果您只想获取已发布帖子的位置:
Category::whereHas('posts',function($q){$q->published();})->get()代码>@tptcat是。也可以是Category::has('postsPublished')
在这种情况下,干净的问题,干净的答案!
