django - django 中的抽象形式或形式组合？

Question

我有一个表格:

class RideForm(forms.Form):
    # a lot of field
    # fields accorded to geography
    # fields accorded to condition

    def clean(self, *args, **kwargs):
        # clean of all fields

我想这样拆分(这只是一个概念，我写这个只是为了说明想法)。 :

class RideGeographyPartForm(...):

    # fields accorded to geography

    def clean(self, *args, **kwargs):
        # clean only geography group of field

class RideConditionPartForm(...):

    # fields accorded to condition

    def clean(self, *args, **kwargs):
        # clean only geography group of field


class RideForm(RideGeographyPartForm, RideConditionPartForm, forms.Form):


    def clean(self, *args, **kwargs):
        # this should internaly call all clean logic from
        # RideGeographyPartForm, RideConditionPartForm

我现在不知 Prop 体怎么做。我尝试使用 mixin，但在字段初始化方面存在一些问题，应该兼顾内部方法的调用。我可以使用抽象模型对模型做类似的事情 docs .有没有办法用表格来做这种组合？

Answer 1

多重继承不会做你想做的，如果它们都实现了 clean()，只有第一个 mixin clean() 会被调用。简单的多态性怎么样？

class RideForm(RideConditionPartForm):

    def clean():
        super clean()
        #other stuff

class RideConditionPartForm(RideGeographyPartForm):
   def clean():
     super clean()
     #other stuff
