Django-方法的签名与类中基本方法的签名不匹配 [英] Django - Signature of method does not match signature of base method in class

问题描述

我正在学习Django，并且正在学习lynda.com课程.在其中的一门课程建设电子学习站点"中，具有以下代码:

I am learning Django and I am following a lynda.com course. In one of there courses "building an elearning site", the have the following code:

class CourseModuleUpdateView(TemplateResponseMixin, View):
    template_name = 'courses/manage/module/formset.html'
    course = None

    def get_formset(self, data=None):
        return ModuleFormSet(instance=self.course,
                             data=data)

    def dispatch(self, request, pk):
        self.course = get_object_or_404(Course, id=pk, owner=request.user)
        return super(CourseModuleUpdateView, self).dispatch(request, pk)

    def get(self, request, *args, **kwargs):
        formset = self.get_formset()
        return self.render_to_response({'course': self.course,
                                        'formset': formset})

    def post(self, request, *args, **kwargs):
        formset = self.get_formset(data=request.POST)
        if formset.is_valid():
            formset.save()
            return redirect('manage_course_list')
        return self.render_to_response({'course': self.course,
                                        'formset': formset})

但是我从以下位置收到来自PyCharm(我的IDE)的错误消息:

But I am getting an error message from PyCharm (my IDE) on:

def dispatch(self, request, pk):

错误是:

Signature of method 'CourseModuleUpdateView.dispatch()' does not match signature of base method in class 'View' less... (Ctrl+F1) 
This inspection detects inconsistencies in overriding method signatures.

我是否可以解决此问题并查看如何开始解决错误?Pycharm甚至想告诉我什么?

Is there a way for me to troubleshoot the issue and see how to begin fixing the error? What is Pycharm even trying to tell me??

我正在使用python 3和DJango 1.11

推荐答案

您正在覆盖签名为 def的父类 View 的方法 dispatch dispatch(self，request，* args，** kwargs):与您看到的不匹配.

You're overriding a method dispatch of the parent class View whose signature is def dispatch(self, request, *args, **kwargs): which you can see from yours does not match.

这里的签名意味着方法参数应与您要覆盖的父类方法匹配.

Signature here means that the method arguments should match with parent class method you're overriding.
