校验器
自义校验函数
def clean_name(self):
value = self.cleaned_data['name']
if '大壮' in value:
raise ValidationError('含有敏感词汇')
else:
return value
def clean(self):
#所有通过校验的数据
value = self.cleaned_data
p1 = value['password']
p2 = value['r_password']
if p1==p2:
return value
else:
self.add_error('r_password','两次输入密码不一致')
raise ValidationError('两次输入的密码不一致')
forms 插件 动态生成数据
publishs = forms.ModelChoiceField(
required=True,
label='出版社',
queryset= models.Publish.objects.all(),
error_messages={
'required': '不能为空',
},
widget=forms.widgets.Select()
)
authors = forms.ModelMultipleChoiceField(
label='作者',
queryset= models.Author.objects.all(),
error_messages = {
'required': '不能为空',
}, )

super().__init__(*args,**kwargs)
#self.fields 是有序字典
for field in self.fields.values():
field.widget.attrs.update({'class':'form-control'})iframe 嵌入别的网页
