Django 表单不显示，除了提交按钮

Question

我遇到了 django 表单未显示在网页上的问题。 唯一显示的是提交按钮。 我无法弄清楚这个问题。

视图.py

class NewThreadView(CreateView):
    model = Thread
    form_class = NewThreadForm
    template_name = 'thread/newthread.html'

    def get_context_data(self, *args, **kwargs):
        context = super(NewThreadView, self).get_context_data(*args, **kwargs)

forms.py

class NewThreadForm(forms.ModelForm):
    class Meta:
        model = Thread
        fields = ('name', 'body', 'author', 'thread_forum')

        widgets = {
            'name': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Enter title'}),
            'body': forms.Textarea(attrs={'class': 'form-control'}),
            'author': forms.TextInput(attrs={'class': 'form-control', 'value': '', 'id': 'author', 'type': 'hidden'}),
            'thread_forum': forms.Select(attrs={'class': 'form-control', 'type': 'hidden'}),
        }

新线程.html

<div class="form-group">
     <form method="post">
        {% csrf_token %}
        {{ form.as_p }}
        <button type="submit" class="btn btn-primary" name="thread_submit">Create Thread</button>
    </form>
</div>

您的上下文未返回，因此模板无法呈现任何内容。 您需要返回上下文；

class NewThreadView(CreateView):
    model = Thread
    form_class = NewThreadForm
    template_name = 'thread/newthread.html'

    def get_context_data(self, *args, **kwargs):
        context = super(NewThreadView, self).get_context_data(*args, **kwargs)
        return context
