问题描述
使用 Eloquent ORM 我的模型设置如下:Post
belongsToMany
Category
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');
}
我想按类别关系的列过滤帖子.
I want to filter posts by a column of the categories relationship.
所以我想做类似的事情:
So I want to do something like:
$posts->where('categories.slug', '=', Input::get('category_slug'));
但这不起作用.
我也试过:
$with['categories'] = function($query){
$query->where('slug', '=', Input::get('category_slug'));
};
$posts::with($with)->get();
但我认为这是过滤类别而不是按类别过滤.
But I thnk that's for filtering the categories not filtering BY the category.
谁能给我指路?
推荐答案
我现在无法访问我的 Vagrant box,但我相信这应该可行:
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();
