Django template won't display my model variants

Question

Sorry I'm new to Django and programming in general but I'm trying to call on variables from my model to be displayed on a specific page. I mapped my URLs to example.com/archive/book_slug and would like the details like title, author, ISBN, or whatever. I used the blog app to register my models in the admin page.

The problem occurs in my template when I go to the URL nothing gets displayed. I want the title of the book to appear in the header. Can anyone help please?

blog/models.py

from django.db import models

class Book_item(models.Model):
   book_title = models.CharField(max_length=255, blank=False)
   book_author = models.CharField(max_length=255)   
   book_publisher = models.CharField(max_length=255, blank=True)
   book_date_published = models.IntegerField(blank=True)
   book_isbn = models.IntegerField(blank=True)
   book_slug = models.SlugField(max_length=255, unique=True, blank=False,
                                primary_key=True)
   book_body = models.TextField(blank=True)

def __unicode__(self):
    return self.book_title

blog/views.py

from django.shortcuts import render, get_object_or_404
from blog.models import Book_item

# view for /achive/; template at archive.html
def archive_index(request):
    book_info = Book_item.objects.all()
    context = {'book_info' : book_info} 
    return render(request, 'blog/archive.html', context)

# view for /archive/book_title; 404 if no title; template at book_detail.html
def book_details(request, book_slug):
    bookdeets = Book_item.objects.filter(book_slug=book_slug)
    details = get_object_or_404(Book_item, book_slug=book_slug)
    context = {'details' : details, 'bookdeets' : bookdeets}
    return render(request, 'blog/book_detail.html', context)

blog/urls.py

from django.conf.urls import patterns, url
from blog import views

urlpatterns = patterns('',

    # archive index at /archive/                   
    url(r'^$', views.archive_index),

    # book deatils at /archive/book_title
    url(r'^(?P<book_slug>[\w-]+)/$', views.book_details),

 )

blog/book_detail.html

{% extends "base.html" %}

{% block title %}{{Book_item.book_title}}{% endblock %}

{% block headercontent %}
<h1>{{Book_item.book_title}}</h1>
{% endblock %}

Answer 1

try using your model name in lower case.

<h1>{{ book_item.book_title }}</h1>
