Constructor Details

#initialize(resource_class, method, options = {}) ⇒ Configuration

By default, a filter type will be selected based upon the attribute type

For example, a date will get a datepicker, a datetime gets a datetime picker A string gets a text search, and a numerical field gets a number search

To provide a select dropdown, such as filtering on an association, simply provide a collection attribute (as a Proc to be evaluated in the view context)

Examples:

filter :id (numeric) filter :device_id (numeric) filter :device_id, collection: ->{ [[1, ‘device’]] } (select) filter :created_at (datetime) filter :created_at, as: :date (date) filter :name (string)
