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并没有太多的经验，但是当视图之间的距离不太远时，它似乎可以解析模板。
我的结构也很糟糕，但是我不知道如何正确构建Django网站。
登录文件（无效）：
<!--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（有效）：
<!--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：模板/基本html模板/注册/登录html模板/用户/仪表板html
网址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")),
]
来自base.html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。它正在尝试使用名为dashboard而不是字符串的变量的值"dashboard"。
<a href="{% url 'dashboard' %}">Back to dashboard</a>
