Module dependency and relations - php

Question

"Some commonly used features, such as user management, comment management, may be developed in terms of modules so that they can be reused easily in future projects." - http://www.yiiframework.com/doc/guide/1.1/en/basics.module
I have a lot of projects that requires a user. Every time quite the same database structure and features. Registration, login, logout etc.
Yii tells me that i can reuse modules. Cool... let's start:
I have 3 parts: User, Campaign and Website.
In this project the CampaignModule has a relation to the UserModule (campaign_user [user_id, campaign_id])
The WebsiteModule has a relation to the CampaignModule and to the UserModule.
I want to reuse the UserModule in other projects with features like registration, login, edit etc.
Actual situation:
After creating models with gii every one has relations and dependencies across the modules.
e.g.
UserModule: 'campaigns' => array(self::HAS_MANY, 'Campaign', 'user_id'),
To use the WebsiteModule it's necessary to include the User- and CampaignModule.
Now i even have to include Website- and CampaignModule to use the UserModule!
I also want to update the UserModule across many projects and maybe build a framework with some basic modules.
What is the right way to plan an architecture like this?

Answer 1

There is a yii-user module, what they do, is they allow you to specify additional relations for the User model, on the module configuration:
/**
* #return array relational rules.
*/
public function relations()
{
$relations = Yii::app()->getModule('user')->relations;
if (!isset($relations['profile']))
$relations['profile'] = array(self::HAS_ONE, 'Profile', 'user_id');
return $relations;
}
So you can do something like:
'modules'=>array(
'user' => array(
...
'relations' => array(
'categories' => array(CActiveRecord::HAS_MANY, 'Category', "user_id"),
'account' => array(CActiveRecord::HAS_ONE, 'Account', "user_id"),
),
...
),
),
