Question

我是django的新手并试图在html文件中显示一个表单，当我在浏览器上访问此特定页面时，我看不到这些字段。

这是html文件：我可以看到所有内容，但显示的形式为two_factor.html

{% extends 'authentication/base.html' %}

{% block title %}Two Factor{% endblock title %}

{% block two_factor %}
    <div class="container">
    <h3>Your code</h3>
    <form role="form" action="" method="post" enctype="multipart/form-data">
        <div class="form-group">
            {% csrf_token %}
            {{ form }}
            <div class="form-group">
                <button type="submit" class="btn btn-success">Submit</button>
            </div>
        </div>
    </form>
</div>
{% endblock two_factor %}

my forms.py

class TwoFactorForm(forms.Form):
    code = forms.CharField(label='Code', widget=forms.TextInput(attrs={'type': 'text', 'placeholder': 'Your code'}))

my views.py

class TwoFactorView(View):
    form_class = TwoFactorForm
    template_name = 'authentication/two_factor.html'

    def get(self, request):
        form = self.form_class(None)
        return render(request, self.template_name, {'form': form})

    def post(self, request):
        form = self.form_class(request.POST)

        if form.is_valid():

            return redirect('authentication/secret.html')

        return render(request, self.template_name, {'form': form})

我在base.html中添加了块。我只看到按钮提交。网址很好。

将视图类更改为

class TwoFactorView(View):
 form_class = TwoFactorForm
 template_name = 'authentication/two_factor.html'

 def get(self, request):
    form = self.form_class()
    return render(request, self.template_name, {'form': form})

 def post(self, request):
    form = self.form_class(request.POST)

    if form.is_valid():

        return redirect('authentication/secret.html')

    return render(request, self.template_name, {'form': form})

而不是使用

form = self.form_class(None)

使用

form = self.form_class()

Django表示没有显示的字段
