Django and Tailwind 'TemplateDoesNotExist' error

Question

我遵循本教程：https://www.ordinarycoders.com/blog/article/django-tailwind

我有一个名为"project"的django项目，其中有两个应用程序"app"one_answers"main"。我正在尝试加载'main>模板>main>home.html'。但是我得到了这个错误：

Internal Server Error: /

]

在我的main>urls.py：

from django.urls import path
from . import views
app_name = "main"   

urlpatterns = [
path("", views.homepage, name="homepage"),
]

在main>views.py我有

from django.shortcuts import render
# Create your views here.
def homepage(request):
return render(request = request, template_name="main/home.html")

我已经尝试将main的模板目录添加到settings.中的DIRS中。通过在我的项目中使用另一个Stack链接：Django:TemplateDoesNotExistat/home.html

但是我还没能打开html文件。

非常感谢您的帮助。感谢

嘿，更改settings.py中的这一行从这个

'DIRS': ['C:UsersKaijDocumentsdjangoTestsdjangoTailwind2envprojectmaintemplate'],

到这个

[BASE_DIR/ 'templates']

然后在main目录中创建一个名为templates的文件夹，并在该文件夹中创建另一个名为主的文件夹，这就是home.html所在的位置。所以像这个

project -> main -> templates -> home.html

在名为main的文件夹中，创建一个urls.py并添加这些行

from django.urls import path
from .views import some_view_name
urlpatterns = [
path('', some_view_name, name='home-view')
]

那么主要地->views.py将此行添加到

from django.shortcuts import render
def some_view_name(request):
return render(request, "main/home.html")

这对你来说应该是个问题。

你的目录结构应该像这个

project 
-> project
urls.py
...
-> main
->templates
-> main
-> home.html
manage.py
...

如果这解决了你的问题，请不要忘记接受它作为正确答案。
