Problem With Dataprovider / Datagrid

Yii 1.1 General Discussion
1

Hi,

I am using this code to pull the data from the DB …




$competency_required_level_data = new CActiveDataProvider(CompetencyRequiredLevel::model()->belongsToJobTitle($job_title_id)->with("job_title.job_role.job_role_competencies"), array("criteria" => array("together" => true, "order" => "job_role_competencies.sort_order")));

In my datagrid I am doing …




array(

	"name" => "job_role.name",

	"header" => "Order"

),

The job_role.name just shows an empty column. I have also tried getting data for the job_role_competencies.

The only one I can get data for job_title.

Is there anyway to fix this?

with("job_title.job_role.job_role_competencies")

I didn’t even knew that was possible. Maybe define it as an array of arrays:




with(array(

    "job_title"=>array(

        'with'=>array(

             'job_role'=>array(

                    'with'=>'job_role_competencies'

              ),

         ),

     ),

))

Ok will give it a try.

Ok, I have tried it and it still does not work.

Also bit more information, if I misspell a column it gives me the SQL in the error …

CDbCommand failed to execute the SQL statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘job_role_competences.sort_order’ in ‘order clause’.

I have also tried t3_c3 which is suppose to the job_role_competencies.sort_order but still nothing.

Typo !!

[EDIT]

Ah, sorry.

You have intentionally made a type here … :P

Well, could I ask you what exactly is the problem?

First, what is this belongsToJobTitle() function that you’ve used? It should return a model finder instance instead of actually perfoming any query to the db, make sure it really does that.

Second, it’s better to put the with() in the the criteria too, try this:


$criteria=new CDbCriteria();

$criteria->with=array('job_title', 'job_title.job_role', 'job_title.job_role.job_role_competencies');

$criteria->together=true;

$criteria->order='job_title.job_role.job_role_competencies.sort_order';

$competency_required_level_data = new CActiveDataProvider(CompetencyRequiredLevel::model()->belongsToJobTitle($job_title_id), array(

  	'criteria'=>$criteria

));

Hi everyone,

Thanks for your advice.

In the end I used a CArrayDataProvider and wrote a method to generate the array which gave me more flexibility.
