Re: Accessing variables in referenced tables in views

[Andrew Alexander]

So am I approaching this the wrong way?
I could make a method in my controller to retrieve the variables, but
that seems like bad design to me

And yes thread.php and post.php has a belongsTo User.

post.php:
var $belongsTo = array(
'Thread' => array(
'className' => 'Thread',
'foreignKey' => 'thread_id',
'conditions' => '',
'fields' => '',
'order' => ''
),
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);

Placing "" in view.ctp gives me the error:
Notice (8): Undefined variable: threads [APP\views\threads\view.ctp,
line 1]

If I use the "$thread" variable instead, I get an array with posts and
their user_ids but not the usernames:
"Array ( [Thread] => Array ( [id] => 7 [subject] => c [user_id] => 5
[body] => c [created] => 2010-08-16 14:00:31 [modified] => 2010-08-16
14:00:31 ) [User] => Array ( [id] => 5 [username] => root [password]
=> 6abfa9223de79de9fbb2327c8c999043c2210177 [group_id] => 1 [created]
=> 2010-08-16 12:20:32 [modified] => 2010-08-16 12:20:32 ) [Post] =>

Accessing variables in referenced tables in views

[Andrew Alexander]

I am attempting to create a forum in php. In my project I have tables:
threads, posts, users. And each post has a foreign key for a thread
and a user. In my thread view I want to replace the user_id field with
the corresponding username for each post. I've tried "echo
$post['User']['username'];" but that gives me an error.

Is there a way to access the username variable from the thread view?


Here's the code I have in view now:

>





Html->link(__('View', true), 
array('controller'
=> 'posts', 'action' => 'view', $post['id'])); ?>
Html->link(__('Edit', true), 
array('controller'
=> 'posts', 'action' => 'edit', $post['id'])); ?>
Html->link(__('Delete', true),
array('controller' => 'posts', 'action' => 'delete', $post['id']),
null, sprintf(__('Are you sure you want to delete # %s?', true),
$post['id'])); ?>
