Paginate on hasManyThrough returns first level relation

[andrewdacenko]

For example:

Database Structure

countries
  id
  name

users
  id
  email
  password
  country_id

posts
  id
  title
  description
  user_id

And in Country model we have:

<?php
class Country extends Eloquent {
    public function users()
    {
        return $this->hasMany('User');
    }

    public function posts()
    {
        return $this->hasManyThrough('Post', 'User');
    }
}

<?php
class User extends Eloquent {
    public function country()
    {
        return $this->belongsTo('Country');
    }

    public function posts()
    {
        return $this->hasMany('Post');
    }
}

If we search for all post in country like this $country->posts - we get the correct data, also using $country->posts()->take(10)->get() - we also get right data from posts table.

But if we call for $country->posts()->paginate() - we get paginated data from users table.

You mean you "only" get paginated data from the users table, or the paginated data includes both users and posts?

[andrewdacenko]

Yeap, paginate returns Only users data, no posts data included.

This has been fixed.

no not fixed, connection is lost when adding pagination
