python - Django - 将新模型与他们自己的页面结合起来
问题描述
我已经设法在我的 Django 项目中设置了一个模型，并且可以在其中创建帖子并通过视图和模板显示这些帖子，但是，我似乎无法对我创建的新模型做同样的事情。我尝试像对初始模型所做的那样执行此操作，即设置自己的 html 文件，就像第一个一样，以及主项目文件夹中 urls.py 和 view.py 中的类似条目应用程序文件夹。
编辑以获取更多上下文：基本上，文章模型已使用模板 article_detail.html 和 article_list.html 设置，并且该模型中的所有条目都从管理应用程序中提取并且可以查看。我创建了另一个模型，进攻性，并且也想对文章条目做同样的事情，所以我尝试复制我所做的并将进攻性模型制作为自己的模板（offensive_detail.html 和进攻性列表.html:)。然而，这似乎没有奏效。在 base_template.html 上为 Offensive 创建链接不会去任何地方，它只是停留在同一页面上。不重定向到将显示攻击性文章列表的攻击性详细信息页面。
我的目的是让不同的类别与不同的模型保持一致，并将所有这些类别和相应的页面作为导航栏中的链接。
我不完全确定我哪里出错了，或者即使我接近正确。帮助将不胜感激。
app文件夹下的文件：
article_detail.html：

从主文件夹“网站”：

"""website URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/3.1/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'))

解决方案
您的网址似乎有点不同步。您已经包含了两次articles.urls 和两个匹配'r'^$' 的模式。
你有什么：
url(r'^admin/', admin.site.urls),
url(r'^articles/', include('articles.urls')),
url(r'^about/$', views.about),
url(r'^$', article_views.article_list, name="home"),
url(r'^offensive/', include('articles.urls')),
url(r'^$', article_views.offensive_list, name="offensive"),
我认为你可能想要的：
url(r'^admin/', admin.site.urls),
url(r'^articles/', include('articles.urls')),
url(r'^offensive/', include('offensive.urls')),
url(r'^about/$', views.about),
# pick one of the following that you want for the root url
# currently will match the first one.
url(r'^$', article_views.article_list, name="home"),
url(r'^$', article_views.offensive_list, name="offensive"),
或者如果只是模型分离，把它们合二为一？
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^articles/', views.article_list, name="article_list"),
url(r"^articles/(?P<slug>[\w-]+)/$", views.article_detail, name="article_detail"),
url(r'^offensive/', views.offensive_list, name="offensive_list"),
url(r"^offensive/(?P<slug>[\w-]+)/$", views.offensive_detail, name="offensive_detail"),
url(r'^about/$', views.about),
url(r'^$', views.about, name="home"),
]
此外，您可能希望使用较新的路径，而不是 url ( https://docs.djangoproject.com/en/3.1/topics/http/urls/#example )
