How to map Eloquent with other tables? - orm

Question

This is the first time when i use ORM, so i wondering if it is possible to map it to other tables...
For example i have currently logged user. It is connected to the POSTS table through links table. For example if i want to select posts i do sql like this:
SELECT
`posts`.`id`', `posts`.`Name`, `posts`.`Description`
FROM
`links`,
`posts`
WHERE
`links`.`user_id` = 1 AND `links`.`post_id` = `posts`.`id`
How to extend Eloquent that if i request Posts::all() it would return posts only for current user...

Answer 1

You can define a query scope in your POST modal
public function scopeOfUser($query,$user_id)
{
return $query->join('links', 'links.post_id', '=', 'posts.id')
->where('links.user_id', '=', $user_id)
->select('posts.id', 'posts.Name', 'posts.Description');
}
Then use it like this:
$posts = POST::OfUser(1)->get();

Your post is a bit confusing but I hope my answer addresses it as you expect.
Warning:
Please refer to Laravel's (Many to Many) Relationship documentation for details.
To make things simple and comply with the Laravel convention, I strongly suggest you to use post_userinstead of link as the pivot table (post_user table should have user_id and post_id as columns).
You don't have to define a corresponding pivot model (that's the convention).
The following models are meant to map to respectfully the tables users and posts.
User Model:
in app/model/user.php (already there, just add the relationship definition)
class User extends Eloquent {
...
public function posts()
{
return $this->belongsToMany('Post');
}
...
}
Post Model:
in app/models/post.php (to be created of course).
...
class Post extends Eloquent {
public function users()
{
return $this->belongsToMany('User');
}
}
...
Retrieval of a user's posts:
Usually, you do the following in Laravel to get the current logged user:
$user = Auth::user(); // a User model / record
Assuming $user is of type User (Model), you can retrieve all its posts using:
$user->posts(); // a Collection
