Laravel Eloquent Joins - php

Question

I have below query in core php:
SELECT DISTINCT device_tocken FROM push_details JOIN users ON users.id=push_details.user_id
I have to integrate it in laravel 4
Application already have User extends Eloquent class
I created Push_details class as below
class Push_details extends Eloquent {
public $table = 'push_details';
public function User() {
return $this->hasMany('\User','id');
}
}
Table : users
Primary key : id
Table: push_details
Primary key: id
Foreign key: user_id belongsTo('users.id');
But i m not able to get expected result.
One more thing i didn't write anything in User's model yet.

Answer 1

Only way to join table is.. to join it, as Eloquent relations don't work using joins but separate queries with WHERE IN clauses. So this will do:
DB::table('push_details')
->select('device_tocken')
->distinct()
->join('users','users.id','=','push_details.user_id')
->get();
Above will return array of stdObject's so or if you need Eloquent Collection with Eloquent models as a result replace DB::table('push_details')->select... with PushDetails::select...
Now, correct your relations, as they are wrong:
// PushDetails model (as previously stated, I suggest renaming it to StudlyCase)
public function user() {
return $this->belongsTo('\User','user_id'); // user_id is may be omitted here
}
// User model
public function pushDetails() {
return $this->hasMany('\PushDetails','user_id'); // user_id is may be omitted here as well
}

Answer 2

In your User model, you need to link back to the PushDetails model, like so
class User extends Eloquent {
public function push_details() {
return $this->belongsTo('PushDetails');
}
}
Use CamelCase for Class names, because laravel has several functions, in which CamelCase are changed to snake_case
Change
public function User() {
return $this->hasMany('\User','id');
}
to
public function users() {
return $this->hasMany('User');
}
