Question

我有一个配置文件更新表单，我已将数据和实例传递给表单，但验证失败。方案如下。

此表单用于配置文件更新，但验证失败但未显示任何错误。

 class ProfileEditForm(forms.ModelForm):
    class Meta:
        model = Profile

    def clean(self):
        return self.cleaned_data

视图如下

＆GT; form.is_valid始终返回False。

def user_profile(request, params={}):
if request.user.is_staff==False:
    profile = Profile.objects.get(user=request.user)
    if request.method == 'POST':
        profile_form = ProfileEditForm(request.POST,  instance=profile) 
        print profile_form.is_bound
        print profile_form.is_valid()
        if  profile_form.is_valid():
            profile = profile_form.save()
        else:
            pass
    else:
        profile_form = ProfileEditForm( instance=profile)  
    profile_form = ProfileEditForm( instance=profile)
    params['profile_form'] = profile_form
    return render_to_response('vec/profile.html', params, context_instance=RequestContext(request))
else:
    return render(request, 'base.html')

以下是产出：

print profile_form.is_bound - 返回True和 print profile_form.is_valid（）返回False。{{profile_form.errors}} {{profile_form.non_field_errors}}
中没有错误。

感谢您的回复...... 提前谢谢......

Answer 1

您在重置profile_form之前将其发送到模板，因此未显示任何错误。

见下面的评论

def user_profile(request, params={}):
    if request.user.is_staff==False:
        profile = Profile.objects.get(user=request.user)
        if request.method == 'POST':
            profile_form = ProfileEditForm(request.POST,  instance=profile) 
            print profile_form.is_bound
            print profile_form.is_valid()
            if  profile_form.is_valid():
                profile = profile_form.save()
            else:
               pass
       else:
            profile_form = ProfileEditForm( instance=profile)  
       # don't do this, you already have profile_form
       #profile_form = ProfileEditForm( instance=profile)

       params['profile_form'] = profile_form
       return render_to_response('vec/profile.html', params, context_instance=RequestContext(request))
    else:
       return render(request, 'base.html')

我想通了......

我刚刚在表单定义中包含了字段

fields = ('','',)

感谢。

表单不更新值，验证失败但没有错误
