Question

我正在django中创建一个联系表单来发送电子邮件，但表单没有显示在网页上。我认为问题可能是因为表单对象可能从未正确传递给上下文，但我不知道它出错的地方。下面的代码是我到目前为止的代码。

from .forms import *

我的观点

def email(request):
    form = ContactForm()
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            subject = form.cleaned_data['subject']
            email = form.cleaned_data['email']
            first_name = form.cleaned_data['first_name']
            message = form.cleaned_data['message']
            try:
                send_mail(first_name + ": " + subject, message, email,
                          ['flavioandersites@gmail.com'])
            except BadHeaderError:
                return HttpResponse("Invalid Header.")
            return redirect('thankyou')
    return render(request, 'Index-App/contact.html', {'form': form})

我的表单类

class ContactForm(forms.Form):
    subject = forms.CharField(required=True)
    from_email = forms.EmailField(required=True)
    first_name = forms.CharField(max_length=200, required=True)
    message = forms.CharField(widget=forms.Textarea)

网址

url(r'^contact/$', views.email, name='contact'),

我的模板

{% block contact %}
    <form method="POST" action="{% url 'Index-App:contact' %}">
      {% csrf_token %}
      {{ form }}
    <input type="submit" class="btn-success" value="Send"/>
    </form>
    {% endblock %}

因为当方法为GET时，您没有实例化表单。此外，您需要将self参数更改为request

尝试以下方法：

def email(request):  # pass request for your view param, not self
    form = ContactForm()  # You should instantiate your form for GET method
    if request.method == 'POST':
        form = ContactForm(request.POST)
        # ...
    return render(request, 'Index-App/contact.html', {'form': form})

我的表单没有显示字段，我无法弄清楚原因
