Issue
I'm trying write an website with Laravel (current version is 5.7) and I have 3 models as: Post, User and Fav. I'm using a simple form to add posts to "favs" table which has 3 columns as; id, user_id and post_id. And I want to list posts that user added favorites bu I can't use "hasMany" method properly.
I can use variables like; $post->user->name but I can't figure it out how to use relationship with "favs" table.
Post Model
public function user() {
return $this->belongsTo('App\User');
}
public function favs() {
return $this->hasMany('App\Fav');
}
Fav Model
public function users() {
return $this->hasMany('App\User');
}
public function posts() {
return $this->hasMany('App\Post', 'post_id', 'id');
}
User Model
public function posts() {
return $this->hasMany('App\Post');
}
public function favs() {
return $this->hasMany('App\Fav');
}
Controller
public function user($id){
$favs = Fav::orderBy('post_id', 'desc')->get();
$user = User::find($id);
$posts = Post::orderBy('id', 'desc')->where('user_id', $id)->where('status', '4')->paginate(10);
return view('front.user')->with('user', $user)->with('posts', $posts)->with('favs', $favs);
}
Solution
The Fav
model only has one User
and Post
each, so you need to use belongsTo()
instead of hasMany
and change the method names to singular. You can also remove the additional parameters in post()
since they're the default values.
public function user() {
return $this->belongsTo('App\User');
}
public function post() {
return $this->belongsTo('App\Post');
}
Loading all Post
s that a user has favorited:
$user->favs()->with('post')->get();
The with()
method is used to eager load the relationship.
Now you can loop through the Fav
s:
@foreach($favs as $fav)
{{ $fav->post->name }}
@endforeach
