创建类的两种方式

1、直接创建

from django.forms import ModelForm

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

　　

2、通过“type”创建

from django.forms import ModelForm

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