How to filter data for an attribute that is not part of the Datagrid object?

[edulima]

I am trying to add a filter to my page but the column name I am trying to filter is not part of the object assigned to the Grid. It was dynamically added to the table of results.

Given the object/model: Car

For example this: filter(:status, :enum, select: ['Good', 'Bad']) works fine, as :status is an attribute of Car.

In the case of this filter(:name, :enum, select: ['A1', 'A5']) fails because :name is part of another object and not part of the Car object. Of course this is just a sample object and adding :name is not an option for my real data model.

Query Error: Car.name Undefined column name.

Can this type of filter be achieved?

Where is name stored? How the object that holds it is associated to Car?
