创建类的两种方式

from django.forms import ModelForm

class TestModelForm(ModelForm):
    class Meta:
        model = self.model_class  #表所对应的类
        fields = "__all__"

from django.forms import ModelForm

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