Hey everyone,
Right I am trying to learn datamapper and I am slowly getting there but i do have a few questions.
Basically i am trying to port Dove Forums over to datamapper for the new version as I think it will be a huge improvement on performance. However im getting confused when it comes down to saving relationships. Here is what I have worked out :
Parent Forums - Can have many Sub Forums.
Sub Forums - Can only have one parent.
Topics - Can have many users and posts, but only have one parent forum.
anyway i moved on to coding the home screen. Now here i need the parent forums and then the sub forums for each parent ... here is the code i have so far :
Code:
// Get required ojects.
$topic = new Topic();
$post = new Post();
$p = new parent_forum();
$s = new sub_forum();
// First let`s get the parent forums.
$p->where('active', 'yes')->get();
foreach($p as $parent)
{
// Now let`s get all the sub forums.
$s->where(array('parent_id' => $parent->id, 'active' => 'yes'))->get();
// foreach sub forum save the relationship.
foreach($s as $sub)
{
$sub->save($parent);
}
// build the parent forums data.
$data['parent_forums'][] = array(
'id' => $parent->id,
'name' => $parent->name,
'description' => $parent->description,
'active' => $parent->active,
);
foreach($s->parent_forum->get()->sub_forum->get() as $forums)
{
// Build the sub forums data.
$data['forums_' . $parent->id][] = array(
'forum_name' => anchor(''.site_url().'/topics/view_topics/'.$forums->id.'', ''.$forums->name.''),
'forum_description' => $forums->description,
'topic_count' => $topic->where(array('parent_forum_id' => $forums->id, 'active' => 'yes'))->count(),
'post_count' => $post->where(array('forum_id' => $forums->id, 'active' => 'yes'))->count(),
);
}
Now the code above creates the relationship between parent and sub forums perfectly but do I have to call the following code every execution ? :
Code:
// foreach sub forum save the relationship.
foreach($s as $sub)
{
$sub->save($parent);
}
As obviously as a admin creates new forums in the admin panel and new sub forums the relationship on the home screen may change and would need to be updated. Would i handle this in the admin panel rather than every time a user visits the page ?
I hope you understand what I mean.
Kind Regards
Chris
