django アプリケーションに問題があります。base.html テンプレートは特定のビューで解析できますが、すべてのビューでは解析できず、エラー コードが返されます。

私はdjangoの経験があまりありませんが、ビューが互いに離れすぎていない場合、テンプレートを解析できるようです。

私も非常に悪い構造を持っていますが、django Web サイトを適切に構造化する方法がわかりません。

ログインファイル (動作しません):

<!--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 %}

ダッシュボード ファイル (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 %}

テンプレートのファイル構造: templates/base html templates/registration/login html templates/users/dashboard html

URL Python ファイル

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 からの問題のある行:

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

これは、html テンプレートの static を含む最初の行にすぎません。[ファイル構造][1]

問題はログイン テンプレートです。dashboardstring ではなく、という名前の変数の値を使用しようとしています"dashboard"。

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