  "#{object_name}[#{input_name}]"
end

#input_name ⇒ Object

When it’s a HABTM or has_many association, Formtastic builds “object_ids”. That doesn’t fit our scenario, so we override it here.

def input_name
  name = method.to_s
  name.concat '_id' if reflection
  name.concat multiple? ? '_in' : '_eq'
end

#input_options ⇒ Object

Include the “Any” option if it’s a dropdown, but not if it’s a multi-select.

def input_options
  super.merge :include_blank => multiple? ? false : I18n.t('active_admin.any')
end

#multiple_by_association? ⇒ Boolean

Would normally return true for has_many and HABTM, which would subsequently cause the select field to be multi-select instead of a dropdown.

Returns:

  • (Boolean)
