我需要一些帮助.我在使用pylint运行代码时收到一些警告,我需要解决这些问题.我在下面解释我的代码.

在这里,我需要关闭最大警告消息,以便评级上升.请做必要的帮助.
最佳答案 这是一个简单的修复.你的doc字符串放错了地方.他们看起来应该更像这样：
class Signup(View):
""" this class is used for user signup """
def get(self, request):
""" this class is used for user signup """
form = UserCreationForm()
return render(request, 'booking/signup.html', {'form': form})
def post(self, request):
""" this function used for post the sign up data """
form = UserCreationForm(request.POST)
if form.is_valid():
form.save()
return redirect('login')
E: 34,11: Instance of ‘AuthenticationForm’ has no ‘is_valid’ member (no-member)
至于这个,pylint显然是错误的(当然假设你的AuthenticationForm是form.Form的一个sublcass)
R: 28, 4: Method could be a function (no-self-use)
如果您对此感到疑惑,那么pylint认为get和post不应该是Signup的方法.那是因为你没有使用自身参数,它必须是类中任何方法的第一个参数.但是pylint再一次显然是错误的,因为基于类的视图就像这样工作.您可能想要为django自定义pylint安装.或者添加这个
def get(self, request): #pylint disable=no-self-use
