django - 访问主页时 Django Rest 框架“NoReverseMatch at /”错误

问题描述

仅当我将参数添加到 RetrieveAPIView url 时，才会发生此错误，如下所示：

urlpatterns = [
    path('newgame/', newGame, name='newgame'),
    path('gameboard<int:pk>/', GameBoardView.as_view(), name='gameboard'),
    path('findgame/', findGame, name='findgame')
]

如果我使用有效 ID 访问游戏板 URL，一切正常，但如果我访问，http://127.0.0.1:8000/我会得到：

NoReverseMatch at /

Reverse for 'gameboard' with no arguments not found. 1 pattern(s) tried: ['api/gameboard(?P<pk>[0-9]+)/$']

Request Method:     GET
Request URL:    http://127.0.0.1:8000/
Django Version:     3.1.7
Exception Type:     NoReverseMatch
Exception Value:    

Reverse for 'gameboard' with no arguments not found. 1 pattern(s) tried: ['api/gameboard(?P<pk>[0-9]+)/$']

Exception Location:     /home/calvin/.local/share/virtualenvs/Online-Chess-UxyP2_C1/lib/python3.8/site-packages/django/urls/resolvers.py, line 685, in _reverse_with_prefix

Error during template rendering

In template /home/calvin/Online-Chess/chess/templates/base.html, error at line 0
Reverse for 'gameboard' with no arguments not found. 1 pattern(s) tried: ['api/gameboard(?P<pk>[0-9]+)/$']

如果我<int:pk>从游戏板 URL 中取出，一切都会再次运行。

这是视图：

class GameBoardView(generics.RetrieveUpdateAPIView):
    permission_classes = ([IsAuthenticated])
    serializer_class = GameBoardSerializer
    queryset = GameBoard.objects.all()

这是我的主要网址，以防万一：

urlpatterns = [
    path('', home, name="home"),
    path('<int:game_id>', game, name="game"),
    path('admin/', admin.site.urls),
    path('users/', include('users.urls')),
    path('api/', include('api.urls')),
    path('rest-auth/', include('rest_auth.urls'))
]

我从其他人那里发现的所有错误似乎都是在他们尝试访问他们的详细视图时出现的，但我的问题恰恰相反。这就像它正在尝试api/gameboard主页之前的网址......

感谢您的任何帮助。

编辑：添加主视图代码：

@login_required(login_url="login")
def home(request):
    return render(request, "home.html")

添加 home.html：

{% extends "base.html" %}
{% load static %}
{% load choosecolor %}
{% block content %}
