我正在创建一个网站，以输入不同产品地点（餐厅，超市，药店）的不同产品的价格
用户可以输入多个产品位置一个产品位置可以具有多个产品一个产品位置（例如餐馆）可以具有多个菜单
所以我有三种模型：1.第一种是“ ProductPlace”，它具有网站用户模型（“ User”）作为foreignKey
第二个是具有“ ProductPlace”模型作为外键的“ Product” 第三是“菜单”（如餐厅菜单），它也具有“ ProductPlace”模型作为外键 我在“ forms.py”文件中创建了与这三个模型关联的表单集。

我想动态添加产品和菜单，但我不能。我只能添加新的产品位置，但不能添加产品或特定产品位置的菜单。
