Django自定义登录页面 [英] Django custom login page

问题描述

我有一个自定义的Django登录页面.我想在用户名或密码字段为空时引发异常.我该怎么办?

I have a custom Django login page. I want to throw an exception when username or password fields are empty. How can I do that?

我的view.py登录方法:

My view.py log in method :

def user_login(request):
    context = RequestContext(request)
    if request.method == 'POST':
        # Gather the username and password provided by the user.
        # This information is obtained from the login form.
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(username=username, password=password)
        print("auth",str(authenticate(username=username, password=password)))

        if user:
            # Is the account active? It could have been disabled.
            if user.is_active:
                login(request, user)
                return HttpResponseRedirect('/')
        else:
            return HttpResponse("xxx.")
    else:
        # Bad login details were provided. So we can't log the user in.
        print ("Invalid login details: {0}, {1}".format(username, password))
        return HttpResponse("Invalid login details supplied.")
    else:
        return render_to_response('user/profile.html', {}, context)

我尝试了一下，但没有成功: 这是forms.py

I tried this and it didn't work: This is forms.py

def clean_username(self):
    username = self.cleaned_data.get('username')
    if not username:
        raise forms.ValidationError('username does not exist.')

推荐答案

您可以使用Django提供的登录视图.因此，您的login.html应该类似于该示例.

You can use login view, which is provided by Django. So your login.html should look like that example.

<form class="login" method="POST" action="/login/">

  {% csrf_token %}

  {{form.as_p}}

  <li><input type="submit" class="logBut" value="Log in"/></li>
  </form>

记住urls.py！

url(r'^login/$','django.contrib.auth.views.login', {'template_name': '/login.html'}),
