Django my models aren't carrying over from file to file - django

Question

I am getting my menu items to display on the ListView page, but when I click on the link, none of the data displays properly.
Here is my menu-carousel.html
{% for item in object_list %}
<li>
<div class="impx-menu-page-item">
<div class="impx-menu-page-content">
<h4>{{ item.title }}</h4>
<div class="impx-menu-page-price">
<h5>${{ item.price }}</h5>
</div>
<p>{{ item.description }}</p>
</div>
</div>
</li>
{% endfor %}
And that works, now here is the broken part, when I got to /menu/1 or /menu/'whatever number'
<div class="container">
<div class="row">
<h3>{{ item.title }}</h3>
</div>
<div class="row">
<div class = "col-sm-12 col-md-4">
<img src="{{ item.image.url }}" height="300px" width="300px" class = "img img-responsive thumbnail"/>
</div>
<div class = "col-sm-12 col-md-4">
<h6>Price: ${{ item.price }}</h6>
<h6>Materials: {{ item.description }}</h6>
</div>
<div class = "col-sm-12 col-md-4">
<p>{{ item.description|safe|linebreaks }}</p><br /><br />
<hr />
<h5></h5>
</div>
<br><br>
</div>
</div>
This is what displays in my browser
<div class="container">
<div class="row">
<h3></h3>
</div>
<div class="row">
<div class = "col-sm-12 col-md-4">
<img src="" height="300px" width="300px" class = "img img-responsive thumbnail"/>
</div>
<div class = "col-sm-12 col-md-4">
<h6>Price: $</h6>
<h6>Materials: </h6>
</div>
<div class = "col-sm-12 col-md-4">
<p><p></p></p><br /><br />
<hr />
<h5></h5>
</div>
<br><br>
</div>
</div>
Here is my urls.py
from django.conf.urls import url, include
from django.views.generic import ListView, DetailView
from django.contrib import admin
from . import views
from home.models import Menu
urlpatterns = [
url(r'^$', views.home, name="home"),
url(r'^menu/$', ListView.as_view(
queryset=Menu.objects.all().order_by("-title")[:25],
template_name="menu-carousel.html")),
url(r'^menu/(?P<pk>\d+)/$', DetailView.as_view(
model = Menu,
template_name="menu-item.html")),
]
and here is my models.py
from django.db import models
from django.conf import settings
class Menu(models.Model):
title = models.CharField(max_length = 140)
price = models.IntegerField()
description = models.TextField()
image = models.ImageField(upload_to = 'media/' )
menu = models.CharField(max_length = 10)
def __str__(self):
return self.title

I suppose you've used the wrong context object name in DetailView template. More details by link:
https://docs.djangoproject.com/es/1.9/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_context_object_name
Try to display menu item id with {{menu.id}} instead of {{item.id}}. Also you can use django debug template to see all context objects.
