问题描述

使用雄辩的ORM我的模型设置如下: Post belongsToMany 类别



Post.php

  public function categories()
{
return $ this-> belongsToMany('Category','posts_categories');
}

我想按类别关系的列过滤帖子。 >

所以我想做一些像:

  $ posts-> where ('categories.slug','=',Input :: get('category_slug')); 

这不行。



我还试过:

  $ with ['categories'] = function($ query){
$ query- > where('slug','=',Input :: get('category_slug'));
};

$ posts :: with($ with) - > get();

但是我想,这是为了过滤不按类别过滤的类别。



任何人都可以显示我的方式?

解决方案

我现在无法访问我的Vagrant框,但我相信这应该工作:

  $ posts = Post :: whereHas('categories',function($ q)
{
$ q-> where('slug','=',Input :: get('category_slug'));

}) - > get() ;


Using the Eloquent ORM I have my models set up like so: Post belongsToMany Category

Post.php

public function categories()
{
    return $this->belongsToMany('Category', 'posts_categories');
}

I want to filter posts by a column of the categories relationship.

So I want to do something like:

$posts->where('categories.slug', '=', Input::get('category_slug'));

This doesn't work though.

I also tried:

$with['categories'] = function($query){ 
    $query->where('slug', '=', Input::get('category_slug'));
};

$posts::with($with)->get();

But I thnk that's for filtering the categories not filtering BY the category.

Can anyone show me the way?

解决方案

I can't access my Vagrant box right now, but I believe this should work:

$posts = Post::whereHas('categories', function($q)
{
    $q->where('slug', '=', Input::get('category_slug'));

})->get();
