我的 django 应用程序有问题。我的 base.html 模板可以在某些视图中解析，但不能在所有视图中解析并返回错误代码

我对 django 没有太多经验，但它似乎可以在视图彼此相距不太远时解析模板。

我的结构也很糟糕，但我不知道如何正确构建 django 网站。

登录文件（不起作用）：

<!--hovedside/templates/registration/login.html-->
{% extends "base.html" %}
{% block body %}
<h2>Login</h2>
<form method="POST">
    {% csrf_token %}
    {{form.as_p}}
    <input type="submit" value="Login"></input>
</form>
<a href="{% url  dashboard %}">Back to dashboard</a>
{% endblock body %}

仪表板文件（作品）：

<!--hovedside/templates/users/dashboard.html-->
{% extends "base.html" %}
{% block body %}
<div class="default-bodycontainer">
    <h1>Hello, {{ user.username|default:'Guest' }}!</h1>
</div>
{% endblock body %}

模板的文件结构：templates/base html templates/registration/login html templates/users/dashboard html

urls python 文件

from django.urls import path
from django.conf.urls import include, url
from . import views

app_name = "hovedside"
urlpatterns =[
    path("", views.index, name="index"),
    path("dashboard/", views.dashboard, name="dashboard"),
    #path("accounts/", include("django.contrib.auth.urls")),
    url(r"^accounts/", include("django.contrib.auth.urls")),
]

base.html 中的问题行：

<link rel="icon" href="{% static 'hovedside/img/favicon.ico' %}">

这只是 html 模板中带有 static 的第一行。[文件结构][1]

问题是您的登录模板。它试图使用名为dashboard而不是 string的变量的值"dashboard"。

<a href="{% url 'dashboard' %}">Back to dashboard</a>

回答：

<a href="{% url 'dashboard' %}">Back to dashboard</a>

正如@schillingt 指出的那样，我需要将其指向字符串仪表板。

其他问题：

这也提出了一个后来的问题，我认为这是因为我的结构，我需要链接到

{% url 'hovedside:dashboard' %}

然后，我需要将其添加到应用程序 hovedside 的 url 中，而不是添加到 mysite 应用程序中，因为包含的链接直接指向：

帐户/登录

代替

stemdirekte/帐户/登录

所以我需要将这些网址添加到这样的 mysite 网址中。 mysite/urls.py：

from django.contrib import admin
from django.urls import path, include


urlpatterns = [
    path('admin/', admin.site.urls),
    path("stemdirekte/", include("hovedside.urls")),
    path("hovedside/", include("hovedside.urls")),
    path("accounts/", include("django.contrib.auth.urls")),
]
