我正在關注這個教程：https ://www.ordinarycoders.com/blog/article/django-tailwind
我有一個名為“project”的 Django 專案，其中有兩個應用程式“app”和“main”。我正在嘗試加載'main > template > main > home.html'。但我收到此錯誤：
Internal Server Error: /

在我的project>urls.py我有：
from django.contrib import admin
from django.urls import path, include #add include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include ('main.urls')), #add this
]
在我的main>urls.py 中：
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")
我嘗試將 main 的模板目錄添加到 settings.py 中的 DIRS 中，并遵循另一個堆疊鏈接： Django: TemplateDoesNotExist at / home.html in my project
但是我一直無法打開html檔案。
非常感謝任何幫助。謝謝
uj5u.com熱心網友回復：
嘿，settings.py
從這里改變你的這一行
'DIRS': ['C:\Users\Kaij\Documents\djangoTests\djangoTailwind2\env\project\main\template'],
對此
[BASE_DIR/ 'templates']
然后在您的main目錄中創建一個名為的檔案夾，templates并在該檔案夾中創建另一個名為 main 的檔案夾，這就是您home.html進入的位置。所以像這樣
project -> main -> templates -> home.html
在名為 main 的檔案夾中，創建一個urls.py并添加這些行
from django.urls import path
from .views import some_view_name
urlpatterns = [
path('', some_view_name, name='home-view')
]
然后在 main -> views.py 中將此行添加到
from django.shortcuts import render
def some_view_name(request):
return render(request, "main/home.html")
那應該是你的一些問題。
你的目錄結構應該像這樣
project
-> project
urls.py
...
-> main
->templates
-> main
-> home.html
manage.py
...
如果這解決了您的問題，請不要忘記接受它作為正確答案。
