Python /\uuuu init\uuuu（）处的TypeError接受1个位置参数，但给出了2个位置参数

我从maxg203复制了这段代码 我又犯了一个错误，但我还是设法解决了，但到了这一次，我花了整整4个小时试图解决它，直到现在我都没能解决 我还是Django的初学者

My Models.py：

from django.db import models
from django.contrib.auth.models import User


class Post(models.Model):
    post = models.CharField(max_length=500)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)


class Friend(models.Model):
    users = models.ManyToManyField(User)
    current_user = models.ForeignKey(User, related_name='owner', null=True, on_delete=models.CASCADE)

    @classmethod
    def make_friend(cls, current_user, new_friend):
        friend, created = cls.objects.get_or_create(
            current_user=current_user
        )
        friend.users.add(new_friend)

    @classmethod
    def lose_friend(cls, current_user, new_friend):
        friend, created = cls.objects.get_or_create(
            current_user=current_user
        )
        friend.users.remove(new_friend)

my Views.py：

from django.views.generic import TemplateView
from django.shortcuts import render, redirect
from django.contrib.auth.models import User

from home.forms import HomeForm
from home.models import Post, Friend


class HomeView(TemplateView):
    template_name = 'home/home.html'

    def get(self, request):
        form = HomeForm()
        posts = Post.objects.all().order_by('-created')
        users = User.objects.exclude(id=request.user.id)
        friend = Friend.objects.filter(current_user=request.user)
        friends = friend.users.all()

        args = {
            'form': form, 'posts': posts, 'users': users, 'friends': friends
        }
        return render(request, self.template_name, args)

    def post(self, request):
        form = HomeForm(request.POST)
        if form.is_valid():
            post = form.save(commit=False)
            post.user = request.user
            post.save()

            text = form.cleaned_data['post']
            form = HomeForm()
            return redirect('home:home')

        args = {'form': form, 'text': text}
        return render(request, self.template_name, args)

def change_friends(request, operation, pk):
    friend = User.objects.get(pk=pk)
    if operation == 'add':
        Friend.make_friend(request.user, friend)
    elif operation == 'remove':
        Friend.lose_friend(request.user, friend)
    return redirect('home:home')

我的表格.py

from django import forms
from home.models import Post


class HomeForm(forms.ModelForm):
    post = forms.CharField(widget=forms.TextInput(
        attrs={
            'class': 'form-control',
            'placeholder': 'Write a post...'
        }
    ))

    class Meta:
        model = Post
        fields = ('post',)
My urls.py
from django.conf.urls import url
from home.views import HomeView
from . import views

urlpatterns = [
    url('', views.HomeView.as_view(), name='home'),
    url('connect/(?P<operation>.+)/(P<pk>\d+)/', views.change_friends, name='change_friends')
]

init（）接受1个位置参数，但给出了2个位置参数

最后，我通过将_as.view放在我的项目的主URL中来解决它
