所以我想做的就是这个。我目前有一件设备上有很多部件。我也有零件库存。我要做的是当你向设备添加一个零件时，它会将它从库存中移除。我目前有部件连接到设备但不知道如何减少数量。以下是零件和设备的管理模型。

非常感谢任何帮助。

您可以在activeadmin中创建一个控制器。
在part.rb中：
ActiveAdmin.register Part do
//the customisation of index, show, form
controller do
def create
@part = Part.new(permitted_params[:part])
// do what you want
if @part.save
redirect_to admin_parts_path
else
render :new
end
end
end
end
对于equipment.rb来说是一样的。希望它有所帮助！
