1、直接創建

from django.forms import ModelForm

class TestModelForm(ModelForm):
    class Meta:
        model = self.model_class  #表所對應的類
        fields = "__all__"

2、通過“type”創建

from django.forms import ModelForm

meta = type(‘Meta‘,(object,),{‘model‘:self.model_class,‘fields‘:‘__all__‘})
TestModelForm = type(‘TestModelForm‘,(ModelForm,),{‘Meta‘:meta})

創建類的兩種方式
