Django - 将新模型与他们自己的页面结合起来

Question

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，我似乎无法对新模型做同样的事情。已创建。我已经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。

编辑以获得更多上下文：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是从管理应用程序中提取的，并且是可见。我已经创建了另一个模型，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 创建一个链接不会去任何地方，它只是停留在同一页面上。不会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，或者即使我几乎是正确的。 非常感谢您的帮助。

Here is the folder structure of my project

app文件夹下的文件：

article_detail.html：

        <p>{{ article.body }}</p>
        <p>{{ article.date }}</p>
    </div>
</div>

{% endblock %}

article_list.html：

{% extends 'base_layout.html' %}

{% block content %}
    <h1>Articles List</h1>
    <div class="articles">
        {% for article in articles %}
           <div class="article">
            <h2><a href="{% url 'articles:detail' slug=article.slug %}">{{ article.title }}</a></h2>
            <p>{{ article.date }}</p>
           </div>
        {% endfor %}

Answer 1

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"),

我想你可能想要什么：

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"),
]

另外，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)
