所以我已经完成我的register()表单，这是正常工作。我现在试图做我的login()表单，但是字段（username和password）没有显示出来，因为我无法在BoxesView()中将2个值添加到form_class。注册表单中的form_class已经有了一个值，所以我需要添加另一个值。说实话，我并不完全确定form_class是如何在这里工作的，或者如果可以添加另一个，所以如果有人能够解释这很好。这里是我的代码：如何在FormMixin中添加两个form_class？
views.py
class BoxesView(ListView, FormMixin):
template_name = 'polls.html' # extends base.html
form_class = UserRegistrationForm
def get_context_data(self, **kwargs):
context = super(BoxesView, self).get_context_data()
question_list = Question.objects.all().order_by('-date')
choice = Choice.objects.all()
context['question_list'] = question_list
context['choice'] = choice
q_list = []
returned_list = []
for i in question_list:
q_list.append(i)
for a, b in CATEGORY_CHOICES:
name = resolve(self.request.path_info).url_name
if b == name:
category = a
search = self.request.GET.get('search')
posts = Post.objects.all().filter(category=category).order_by('-date')
if search:
posts = posts.filter(
Q(title__icontains=search) |
Q(content__icontains=search)
)
else:
posts = Post.objects.all().filter(category=category).order_by('-date')
context['posts'] = posts
total = 0
for post in posts:
returned_list.append(post)
total += 1
if total == 4:
total = 0
for i in q_list:
returned_list.append(i)
q_list.remove(i)
break
paginator = Paginator(returned_list, 14)
page = self.request.GET.get('page')
try:
lst = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
lst = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
lst = paginator.page(paginator.num_pages)
context['lst'] = lst
return context

user.save()
return redirect('/')

return redirect('/')
