我有用户、类别和帖子。用户有很多帖子，类别有很多帖子，帖子属于一个类别和一个用户。
我需要帮助以正确的帖子显示正确的用户。
表
categories{category_id, category_title}
posts{post_id, post_title}
users{user_id, user_title}
categories_posts{category_id, post_id}
users_posts{user_id, post_id}
楷模
class Model_User extends ORM {
protected $_primary_key = 'user_id';
protected $_has_many = array(
'posts'=> array(
'model' => 'post',
'through' => 'users_posts',
'far_key' => 'post_id'
),
);
}
class Model_Category extends ORM {
protected $_primary_key = 'category_id';
protected $_has_many = array(
'posts'=> array(
'model' => 'post',
'through' => 'categories_posts',
'far_key' => 'post_id'
)
);
}
class Model_Post extends ORM {
protected $_primary_key = 'post_id';
protected $_belongs_to = array(
'categories'=> array(
'model' => 'category',
'through' => 'categories_forums',
'far_key' => 'category_id'
),
'users'=> array(
'model' => 'user',
'through' => 'users_posts',
'far_key' => 'user_id'
)
);
}
展示
$categories = ORM::factory('category')->find_all();
foreach ($categories as $category) :
echo $category->category_title;
foreach ($category->posts->find_all() as $post) :
echo $post->post_title;
echo $post->users->user_title;
endforeach;
endforeach;
类别和帖子正确回显，但用户没有。
假设 users_posts 具有以下内容：
user_id post_id
1 1
1 2
1 3
2 4
上面的代码将回显用户一、用户二、NULL、NULL，而不是用户一、用户一、用户一、用户二。由于某种原因，它将帖子一与用户一匹配，将帖子二与用户二匹配，因为它们具有相同的 ID 号。
我究竟做错了什么？
这是假设要回显的内容：
Category One
Post One
User One
Post Two
User One
Category Two
Post Three
User One
Post Four
User Two
这是代码的回声：
Category One
Post One
User One
Post Two
User Two
Category Two
Post Three
NULL
Post Four
NULL
