我有三种模型交易,CellPhoneAttribute和手机设备。 模型之间的关系是:Rails嵌套窗体(使用jquery)
class CellphoneEquipment < ActiveRecord::Base
belongs_to :cellphone_deal_attribute
end
class CellphoneAttribute < ActiveRecord::Base
has_many :cellphone_equipments, dependent: :destroy
accepts_nested_attributes_for :cellphone_equipments, :reject_if => :reject_equipment, allow_destroy: true
def reject_equipment(attributes)
if attributes[:model].blank?
if attributes[:id].present?
attributes.merge!({:_destroy => 1}) && false
else
true
end
end
end
end
class Deal < ActiveRecord::Base
has_many :cellphone_deal_attributes, dependent: :destroy
accepts_nested_attributes_for :cellphone_deal_attributes,:reject_if => :reject_cellphone, allow_destroy: true
private
def reject_cellphone(attributes)
if attributes[:domestic_call_minutes].blank?
if attributes[:id].present?
attributes.merge!({:_destroy => 1}) && false
else
true
end
end
end
end
我有一个交易的形式和这种形式里面我有CellphoneAttribute形式和内部CellphoneAttribute我有CellphoneEquipment形式。一切都很好,直到这里。现在,我希望CellPhoneEquipment表单可以通过Jquery多次打开。请指导我如何做到这一点。
