I have a simple forum style discussion that you have to log in in order to post or read comments.
If you create a post or reply to a post the user id is stored with the post, so that I can identify and display the users name next to the post or comment.
It all works fine except when I delete the user, so now the post still exists but it points to a non existent user and consequently displays an error when I try to access the info in CGridView.
This is part of the view that displays the username in a column.
array(
'header'=>'Started By',
'name' => 'author',
'type'=>'raw',
'value' => '$data->author->username',
'htmlOptions'=>array(
'width'=>'100px',
),
),
‘author’ is a relation
'author' => array(self::BELONGS_TO, 'User', 'author_id')
Is there anyway that I can trap this error so that if the user has been deleted I can replace that with ‘author unknown’ or ‘user deleted’ or similar message.
The other approach would be to create a dummy user and modify all posts associated with the user when the user is deleted to now point to the dummy.
Any suggestions?
