Question

I am trying to get count of proposals for each request that is posted in my site using statistical query.i.e, the count of proposals for each request that the logged in user has posted . I am getting the count of all users by using the code

return array(
   'serviceproposals' => array(self::HAS_MANY, 'Serviceproposal', 'ServiceRequestID'),
   'user' => array(self::BELONGS_TO, 'Buyer', 'user_id'),
   'postCount'=>array(self::STAT, 'serviceproposal', 'ServiceRequestID'),
             );

Database:
User[user_id,name,password],
Provider[user_id,providercompany,providerdetails],
Buyer[user_id,contactinfo],
ServiceRequest[ServiceRequestID,Buyer.user_id,details,date],
ServiceProposal[ServiceProposalId,ServiceRequestID,Provider.user_id,services,propsal_rate]

All suggestions are invited…

Answer 1

For this you need to pass the user_id of the currently logged in user, to the STAT relation.

There are 2 ways of achieving this, use a conditional query, or using Parameterized named scopes

1. Conditional Query.

   • Eager Loading:

     $obj= ServiceRequest::model()->with(array(
         'postCount'=>array('condition'=>'user_id = :param',
         'params' => array(':param' => $user_id))
     ))->findAll(); 
     

   • Lazy Loading:

     $serviceRequestObject->postCount(array(
         'condition'=>'user_id = :param',
         'params' => array(':param' => $user_id)
     ));
     

2. Parameterized Named Scope:
   In your model

   public function postCountUser($fieldValue=5) {
       $this->getDbCriteria()->mergeWith(array(
           'condition' => 'user_id = :param',
           'params' => array(':param' => $fieldValue)
      ));
      return $this;
   }
   

   Then use like:

   • Eager loading:

     ServiceRequest::model()->with('postCount')->postCountUser($user_id)->findAll();
     

   • Lazy Loading:

     $serviceRequestObj->postCount->postCountUser($user_id);
