Question

这是我的第一个Django项目，我无法在表单中获取值。我创建了一个UploadFileForm，在Views中实现了一些基本代码，并在urls.py中映射了url。当我尝试将输入发送到表单时，我的问题就出现了。即使我的表单已填满，也会给我一个错误，说明字段未填写。我已将问题缩小到＆＃39; form.is_valid＆＃39;功能。我的代码中是否缺少某些内容？

upload.html

<form action="{% url 'upload_file' %}" method="post">
    {% csrf_token %}
    {{ form.as_p }}
    {{ form.errors }}
    {{ form.non_field_errors }}
    <input type="submit" value="OK">
</form>

form.py

from django import forms

class UploadFileForm(forms.Form):
    title = forms.CharField(max_length=50)
    file = forms.FileField()

views.py

from django.shortcuts import render
from django.http import HttpResponseRedirect
from .forms import UploadFileForm

def success(request):
    return render(request, 'success.html')

def upload_file(request):
    if request.method == 'POST':
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            handle_uploaded_file(request.FILES['file'])
            return HttpResponseRedirect('success/')
    else:
        form = UploadFileForm()
    return render(request, 'upload.html', {'form': form})

def handle_uploaded_file(f):
    with open('uploaded.txt', 'wb+') as destination:
        for chunk in f.chunks():
            destination.write(chunk)

urls.py

from django.conf.urls import url
from django.views.generic import TemplateView
from . import views

urlpatterns = [
    url(r'^$', views.index, name='index'),
    url(r'^upload/success/', views.success, name='success'),
    url(r'^upload/$', views.upload_file, name='upload_file'),
]

即使填充了值，Django表也无法验证
