django表單系統中，所有的表單類都作為django.forms.Form的子類創建，包括ModelForm 關于django的表單系統，主要分兩種 * 基于django.forms.Form * 基于django.forms.ModelForm
#ModelForm 的創建class UserInfoModelForm(forms.ModelForm): is_rmb = Ffields.CharField(widget=Fwidgets.CheckboxInput()) class Meta: model = models.UserInfo fields = '__all__' # fields = ['username','email'] # exclude = ['username'] labels = { 'username': '用戶名', 'email': '郵箱', } help_texts = { 'username': '...' } widgets = { 'username': Fwidgets.Textarea(attrs={'class': 'c1'}) } error_messages = { '__all__':{ }, 'email': { 'required': '郵箱不能為空', 'invalid': '郵箱格式錯誤..', } } field_classes = { # 'email': Ffields.URLField } # localized_fields=('ctime',) def clean_username(self): old = self.cleaned_data['username'] return olddef index(request): if request.method == "GET": obj = UserInfoModelForm() return render(request,'index.html',{'obj': obj}) elif request.method == "POST": obj = UserInfoModelForm(request.POST) if obj.is_valid(): # obj.save() instance = obj.save(False) instance.save() obj.save_m2m() # PRint(obj.is_valid()) # print(obj.cleaned_data) # print(obj.errors.as_json()) return render(request,'index.html',{'obj': obj})新聞熱點
