当我从其他模型调用数据时，为什么我在yii管理用户时缺少搜索框？

Question

Why does the text box disappear below Created By when I call the value from an other model(admin) relation. How can I get the textbox to display no matter what model relation?

Refer to the screenshot for more information about the problem:

Yii CGridView doesn't create inputFiled for those columns that aren't part of the tables shown (as occurs with relations). If you want to show a filter box (dropdown, or whatever you want, an easy way is to create a custom CDataColumn an use it in your grid:

array(
    'name'=>'customer.createdBy.name',
    'header' => 'Created by',
    'class' => 'application.modules.mine.components.DataColumnCreatedBy',
),

Now define your extended column to render a filter:

class DataColumnCreatedBy extends CDataColumn
{
    public function renderFilterCell()
    {
        echo "<td>";
        echo CHtml::inputField('createdBy');
        echo "</td>";
    }
}
