在 heroku 上部署 DJANGO 应用程序时出现错误 500，除了索引之外的所有内容 带有索引的视图即使使用静态也能完美运行，但其他视图显示错误 500

问题描述

带有索引的视图即使使用静态也能完美运行，但其他视图显示错误 500

The code of my urls.py is next:

from django.contrib import admin
from django.urls import path,include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/',admin.site.urls),path('',include("home.urls",namespace="home")),path('api/',include("api.urls",namespace = "api")),] +static(settings.STATIC_URL,document_root=settings.STATIC_ROOT)

以及我的 urls 主文件夹（应用程序文件夹）中的那个

from django.urls import path
from django.contrib.auth import views as auth_views
from home import views
from django.conf import settings
from django.conf.urls.static import static
app_name="home"

urlpatterns=[

    path('VerItems/',views.VerItems,name="VerItems"),path('VerAutores/',views.VerAutores,name="VerAutores"),path('Agregarautor/',views.Agregarautor,name="Agregarautor"),path('AgregarItem/',views.AgregarItem,name="AgregarItem"),views.Index.as_view(),name="index"),]

最后。设置文件，我知道 BASEDIR 不是每个网站都应该显示的，但是如果我更改它，索引将不再起作用

我不认为问题是静态文件和相关的，因为我的索引显示得很好，但老实说不确定，我已经遇到这个问题好几个小时了，现在不知道该怎么办。也许我需要修改一些网址，但在网上找不到，所以...

这是views.py：
