Question

I have a custom module with a backend page. In the grid, I show the customer email as the user name. By default, Magento adds a filter to every column in the grid. Now, when I try to filter by the customer’s email, I get an exception saying that my custom table doesn’t have an email column. Magento is trying to find that in my custom table. How can I fix this problem, or how can I remove the field of that column so that the admin can’t filter by that field.
Thanks.

Add the option

    'filter' => false

to the column you want to remove the filter from in the grid view (e.g. app/code/core/Mage/Adminhtml/Block/Sales/Order/Grid.php)

    $this->addColumn('email', array(
       'header'    => Mage::helper('module')->__('Email'),
       'align'     =>'left',
       'index'     => 'email',
       'filter' => false,
   ));
