404找不到页面“GET / accounts / login /？next = / profile / HTTP / 1.1”404

Question

我的网址有些问题。我没有任何“帐户/”路线，但是当我想访问“登录/”时，我登录后应该将我重定向到我的个人资料......但它带我走这条路：“http://127.0.0.1:8000/accounts/login/?next=/profile/”

如果我发布了任何不必要的东西，我很抱歉：

forms.views（登录/注销）查看

from django.shortcuts import render, redirect,reverse

from django.utils.http import is_safe_url

    template_name = 'forms/login.html'
    success_url = '/profile/' 
def User_logout(request):
    if request.method == "POST":
        logout(request)
    return redirect(reverse('login'))   

登录表单：

class LoginForm(forms.Form):
email = forms.EmailField(label='email')
password = forms.CharField(widget=forms.PasswordInput)

def form_valid(self,form):
    request=self.request
    next_=request.GET.get('next')
    next_post=request.POST.get('next')
    redirect_path=next_ or next_post or None
    email=form.cleaned_data.get('email')
    password=form.cleaned_data.get('password')
    user=authenticate(username=email, password=password)
    if user is not None:
        login(request, user)
        try:
            del request.session['UserProfile.html']
        except:
            pass
        if is_safe_url(redirect_path, request.get_host()):
            return redirect(redirect_path)
        else:
            return redirect("login")
    return super(LoginView, self).form_invalid(form)

在你mainapp的urls.py中设置一个变量，如下所示

appname='mainapp'

现在在登录视图中添加以下内容

def get_success_url(self):
    return reverse('mainapp:profile')
