showing columns from joined tables in CGridView - php

Question

I joined some tables in model by CDbCriteria my code is something like this :
$crt = new CDbCriteria();
$crt->alias = 'so';
$crt->select = 'u.id, u.first_name, u.last_name';
$crt->join = " inner join " . Flow::model()->tableName() . " as fl on fl.id = so.flow_id";
$crt->join .= " inner join " . RoleUser::model()->tableName() . " as ru on ru.id = fl.receiver_role_user_id";
$crt->join .= " inner join " . User::model()->tableName() . " as u on ru.user_id= u.id";
$crt->compare('sms_outbox_group_id', $smsOutboxGroupId);
$crt->compare('fl.kind', Flow::KIND_SMS);
$crt->group = 'u.id';
$smsOutBox = new SmsOutbox();
return new CActiveDataProvider($smsOutBox, array(
'criteria' => $crt,
'sort' => array(
'defaultOrder' => 'so.id DESC',
)
));
how can I show my selected column in CGridView? is there any possible way to show first_name and last_name without defining relation in model?

Answer 1

I've found the solution using Sudhanshu Saxena answer. beside using aliases for first_name and last_name I've added two property to model with same names as aliases : receiverFirstName and receiverLastName. in this way my problem was solved and besides that it provide search functionality on this two property.
my final code is like this :
Model :
public $receiverFirstName;
public $receiverLastName;
creating criteria :
$crt = new CDbCriteria();
$crt->alias = 'so';
$crt->select = 'so.id,u.id as userId, u.first_name as receiverFirstName, u.last_name as receiverLastName, so.status';
$crt->join = " inner join " . Flow::model()->tableName() . " as fl on fl.id = so.flow_id";
$crt->join .= " inner join " . RoleUser::model()->tableName() . " as ru on ru.id = fl.receiver_role_user_id";
$crt->join .= " inner join " . User::model()->tableName() . " as u on ru.user_id= u.id";
$crt->compare('sms_outbox_group_id', $smsOutboxGroupId);
$crt->compare('u.first_name', $this->receiverFirstName, true);
$crt->compare('u.last_name', $this->receiverLastName, true);
$crt->compare('so.status', $this->status);
$crt->compare('fl.kind', Flow::KIND_SMS);
$crt->group = 'userId';
$crt->order = 'so.id';
return new CActiveDataProvider($this, array(
'criteria' => $crt,
));
and finally in CgridView I did this :
'columns' => array(
array(
'header' => Yii::t('app', 'Row'),
'value' => '$this->grid->dataProvider->pagination->currentPage * $this->grid->dataProvider->pagination->pageSize + ($row+1)',
),
array(
'name' => 'receiverFirstName',
'value' => '$data->receiverFirstName',
),
array(
'name' => 'receiverLastName',
'value' => '$data->receiverLastName',
),
array(
'name' => 'status',
'value' => 'SmsOutbox::getStatusTitle($data->status)',
'filter' => CHtml::listData(SmsOutbox::getStatusList(), 'id', 'title')
),
),

Use the alias and call it in CgridView like this
$crt->select = 'u.id, u.first_name as fname, u.last_name as lastname';
In your Grid call it.
array('name'=>'name' or 'header'=>'some header','value'=>'$data->fname')
