title: OperationalError at /admin/todo/todo/ in Django
body: <p>I'm making a basic Todo app in Django.</p>
  
  <p>While going to the admin page and clicking on the Todo option:</p>
  
  <p><a href="https://i.stack.imgur.com/Mx9gw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Mx9gw.png" alt="The Todo option i have created"></a>  </p>
  
  <p>It gives me this error:</p>
  
  <p><a href="https://i.stack.imgur.com/afaGx.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/afaGx.png" alt="see the address bar"></a></p>
  
  <p>The "todo" string appears twice in the URL. </p>
  
  <p>I have already done the migrations thing and I have added the <code>todo.apps.TodoConfig</code> in the INSTALLED_APPS.</p>
  
  <p>Here is my code:</p>
  
  <p><strong>todo app urls.py</strong></p>
  
  <pre><code>from django.urls import path
  from todo import views
  
  urlpatterns = [
      path('', views.index),
      path('todo/', views.index,)
  ]`
  </code></pre>
  
  <p><strong>todo app views.py</strong> </p>
  
  <pre><code>from django.shortcuts import render
  from django.http import HttpResponse
  
  def index(request):
      return HttpResponse("Hello ")
  </code></pre>
  
  <p><strong>todo app models.py</strong></p>
  
  <pre><code>from django.db import models
  from datetime import datetime
  
  class Todo(models.Model):
      title = models.CharField(max_length = 200)
      text = models.TextField()
      created_at = models.DateTimeField(default=datetime.now)
      def __str__(self):
          return self.title
  </code></pre>
  
  <p><strong>todo app admin.py</strong></p>
  
  <pre><code>from django.contrib import admin
  from .models import Todo
  
  admin.site.register(Todo)
  </code></pre>
  
  <p><strong>The main project urls.py</strong></p>
  
  <pre><code>from django.contrib import admin
  from django.urls import path, include
  
  urlpatterns = [
      path('admin/', admin.site.urls),
      path('ToDoList/', include('ToDoList.urls')),
      path('Todo/', include('todo.urls')),
  
  ]
  </code></pre>
