django rest url 中傳入參數 無法識別 404問題

Django

3.0.2

djangorestframework

3.11.0

在創建新的djaong_rest fram work項目的時候

啟動django項目報錯如下

D:\work\djc_wcapp\djc_wcapp\app\urls.py changed, reloading.

System check identified some issues:

urls.path().

url.py中的文件如下

"""djc_wcapp URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/3.0/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path,re_path
from app import views


urlpatterns = [
    path(r'^gamefile/(?P<gm_id>\d+)$', views.GameFileDBDeatailView.as_view()),  # 增刪改查
    path(r'^gamefile$',views.GameFileDBView.as_view()), #增刪改查
]

訪問對應的url

提示如下

原因：Django 2.0中的新path()語法不使用正則表達式.你想要的東西：

 url.py修改為re_path

from django.contrib import admin
from django.urls import path,re_path
from app import views


urlpatterns = [
    re_path(r'^gamefile/(?P<gm_id>\d+)$', views.GameFileDBDeatailView.as_view()),  # 增刪改查
    re_path(r'^gamefile$',views.GameFileDBView.as_view()), #增刪改查
]

 

Django 2.0中的新path()語法不使用正則表達式.你想要的東西：

 

path('<int:album_id>/', views.detail, name='detail'),

如果要使用正則表達式,可以使用re_path().

 

re_path(r'^(?P<album_id>[0-9])/$', views.detail, name='detail'),

舊的url()仍然有效,現在是re_path的別名,但將來可能會被棄用.

 

url(r'^(?P<album_id>[0-9])/$', views.detail, name='detail'),
