使用与 CGridView 的关系

我将尽可能清楚地描述该问题。

我有 activeDataProvider:

$dataProvider=new CActiveDataProvider('Menu', array(
    'criteria'=>array(         
       'with' => array('roles'),
    ),
));

然后我使用带有复选框的 CGridView:

$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'menu-grid',
    'selectableRows' => 2,
'dataProvider'=>$dataProvider,
'columns'=>array(
                   'id',
                   'title',
                   array(
                       'class'    => 'SCheckboxColumn',
                       'header'   => 'View',
                       'name'     => 'Roles[Actions][can_view]',
                       'id'       => 'roles_action_can_view',
                       'value'    => '$data->id',
                       'checkBoxHtmlOptions' =>
                                      array('checked' => $data->roles->can_view),
        ),
    ),
));

然后在菜单模型关系中:

return array(
        'roles' => array(self::HAS_MANY, 'Rolesmenus', 'menu_id'),
    );

和在 Rolesmenus 模型关系中:

return array(
        'menu' => array(self::BELONGS_TO, 'Menu', 'menu_id'),
    );

所以，当我 var_dump 所有 $data 对象时，我无法访问 $data->roles->can_view 变量可以在 _attributtes 私有数组中看到这些属性，但我无法通过 CGridView 访问它们。

有什么想法吗？

I'll describe the problom as clearly as I can.

I have activeDataProvider:

$dataProvider=new CActiveDataProvider('Menu', array(
    'criteria'=>array(         
       'with' => array('roles'),
    ),
));

then I'am using CGridView with checkbox:

$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'menu-grid',
    'selectableRows' => 2,
'dataProvider'=>$dataProvider,
'columns'=>array(
                   'id',
                   'title',
                   array(
                       'class'    => 'SCheckboxColumn',
                       'header'   => 'View',
                       'name'     => 'Roles[Actions][can_view]',
                       'id'       => 'roles_action_can_view',
                       'value'    => '$data->id',
                       'checkBoxHtmlOptions' =>
                                      array('checked' => $data->roles->can_view),
        ),
    ),
));

Then in Menu Model relations:

return array(
        'roles' => array(self::HAS_MANY, 'Rolesmenus', 'menu_id'),
    );

and in Rolesmenus Model relations:

return array(
        'menu' => array(self::BELONGS_TO, 'Menu', 'menu_id'),
    );

So, I cant access $data->roles->can_view variable, when I var_dump all $data object I can see these attributes in _attributtes private array but I cant them access through CGridView.

Any ideas??

array('checked' => $data->roles->can_view,)，

需要
array('checked' => '$data->roles->can_view',),

当您的关系是 HAS_MANY 时，调用该关系将返回该 ActiveRecord 的数组。 CGridView 不会显示数组，因此我过去所做的是在模型中编写一个函数，其中包含获取数组中所有值并从中创建字符串的关系。例如，在菜单模型中的示例中执行类似的操作，

public function rolesToString()
{
    $roles = $this->roles;
    if($roles) {
        $string = '';
        foreach($roles as $role) {
            $string .= $role->can_view . ', ';
        }
        return substr($string,0,strlen($string)-1); // substr to remove trailing comma
    }
    return null;
}

那么该列的 CGridView 的“value”属性应如下所示

'value'=>'$data->rolesToString()'

有一些有关使用 HAS_MANY、with 和 CGridView 此处

When your relation is a HAS_MANY then calling that relation will return an array of that ActiveRecord. The CGridView won't display an array, so what I have done in the past is write a function in the model that contains the relation to take all the values in the array and create a string from them. For example with your example in the menu model do something like this

public function rolesToString()
{
    $roles = $this->roles;
    if($roles) {
        $string = '';
        foreach($roles as $role) {
            $string .= $role->can_view . ', ';
        }
        return substr($string,0,strlen($string)-1); // substr to remove trailing comma
    }
    return null;
}

then the 'value' attribute of the CGridView for that column should look like this
