Instance Method Details

#active_scaffold_search_boolean(column, options) ⇒ Object Also known as: active_scaffold_search_checkbox

we can’t use active_scaffold_input_boolean because we need to have a nil value even when column can’t be null to decide whether search for this field or not

#active_scaffold_search_for(column) ⇒ Object

This method decides which input to use for the given column. It does not do any rendering. It only decides which method is responsible for rendering.
