Question

每当我使用'LoginForm' object has no attribute 'as_widget'时，我都会收到错误formset。我真的不知道是什么问题，因为表格正常呈现正常的Django表单。我试图看看formset中django-widget-tweaks的哪些特征会给{% render_field field class="form-control" placeholder=field.label %}带来这个问题，但到目前为止很难弄清楚。我在HTML代码中的class LoginForm(ModelForm): user_login = forms.HiddenInput() prefix = 'prefix_login' class Meta: model = Usermie fields = ['email', 'password'] widgets = {'password': forms.PasswordInput(), 'email': forms.EmailInput()}收到错误。

forms.py：

def manage_articles(request):
    article_formset = formset_factory(LoginForm)
    book_formset = formset_factory(SignUpForm)
    if request.method == 'POST':
        if 'login' in request.POST:
            login = article_formset(request.POST, request.FILES, prefix='login')

            if login.is_valid():
                email = request.POST.get('prefix_login-email', '')
                password = request.POST.get('prefix_login-password', '')

                # Return a user_obj object if the username and password are valid
                # otherwise it will return null, the null variable is called None in python
                user_obj = auth.authenticate(email=email, password=password)
                # return HttpResponse("inside form if condition")
                if user_obj is not None:
                    if user_obj.is_active:
                        login_usermie(request, user_obj)
                        return HttpResponseRedirect('/home/')
                    else:
                        # pass
                        return HttpResponse("Your account is inactive.")

        elif 'signup' in request.POST:
            signup = book_formset(request.POST, request.FILES)
            if signup.is_valid():
                pass
    else:
        login = article_formset
        signup = book_formset
        return render(request, 'usermie/formtest.html', {
            'login': login,
            'signup': signup,
        })

模板中的

login变量是一个formset。所以当你做以下时：

{% for field in login %}
     {% render_field field class="form-control" placeholder=field.label %}
{% endfor %}

您的表单为field值，而不是字段。尝试这样做：

{% for form in login %}
     {% for field in form %}
         {% render_field field class="form-control" placeholder=field.label %}
     {% endfor %} 
{% endfor %}

Django formset不使用django-widget-tweaks渲染
