Django: OperationalError Нет такой таблицы

Я создаю довольно простое приложение, исследование, в моем проекте Django, который использует Django-CMS. (Это моя первая попытка наложения на проект/приложение.) Основная цель - хранить различные интеллектуальные активы (например, статью, книгу и т.д., Написанную исследователем).

Проблема заключается в том, что когда я указываю браузер на /research/, я получаю сообщение об ошибке, указывающее, что таблица "research_journal" не существует ( "нет такой таблицы" ).

Я использую Djnago 1.6.5 с базой данных sqlite3.

Глядя на python manage.py sql research, получаем:

BEGIN;
CREATE TABLE "research_researchbase" (
    "id" integer NOT NULL PRIMARY KEY,
    "pub_date" datetime NOT NULL,
    "authors" varchar(200) NOT NULL,
    "year" varchar(25) NOT NULL,
    "title" varchar(200) NOT NULL,
    "subtitle" varchar(200) NOT NULL,
    "image_id" integer NOT NULL REFERENCES "filer_image" ("file_ptr_id"),
    "link" varchar(200) NOT NULL
)
;
CREATE TABLE "research_journal" (
    "researchbase_ptr_id" integer NOT NULL PRIMARY KEY REFERENCES "research_researchbase" ("id"),
    "journal" varchar(200) NOT NULL,
    "abstract" text NOT NULL,
    "citation" varchar(200) NOT NULL
)
;
CREATE TABLE "research_encyclopedia_chapter" (
    "researchbase_ptr_id" integer NOT NULL PRIMARY KEY REFERENCES "research_researchbase" ("id"),
    "encyclopedia" varchar(200) NOT NULL,
    "publisher" varchar(200) NOT NULL,
    "summary" varchar(200) NOT NULL
)
;
CREATE TABLE "research_book" (
    "researchbase_ptr_id" integer NOT NULL PRIMARY KEY REFERENCES "research_researchbase" ("id"),
    "publisher" varchar(200) NOT NULL,
    "summary" varchar(200) NOT NULL
)
;

COMMIT;

Я запустил python manage.py migrate research и получил:

/Users/XXX/Documents/repos/sfs/env/lib/python2.7/site-packages/app_data/fields.py:2: DeprecationWarning: django.utils.simplejson is deprecated; use json instead.

Здесь models.py:

from django.db import models
from django.utils import timezone
from filer.fields.image import FilerImageField

import datetime

class ResearchBase(models.Model):
    pub_date = models.DateTimeField('date published')
    authors = models.CharField(max_length=200)
    year = models.CharField(max_length=25)
    title = models.CharField(max_length=200)
    subtitle = models.CharField(max_length=200, blank=True)
    image = FilerImageField()
    link = models.CharField(max_length=200, blank=True)

    def __unicode__(self):
        return self.title

    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)


class Journal(ResearchBase):
    journal = models.CharField(max_length=200)
    abstract = models.TextField()
    citation = models.CharField(max_length=200)


class Encyclopedia_Chapter(ResearchBase):
    encyclopedia = models.CharField(max_length=200)
    publisher = models.CharField(max_length=200)
    summary = models.CharField(max_length=200)


class Book(ResearchBase):
    publisher = models.CharField(max_length=200)
    summary = models.CharField(max_length=200)

Здесь my views.py(обратите внимание, что я передаю два объекта через рендеринг, игнорирую тот факт, что еще не включил класс Books во всей сделке):

from django.shortcuts import render, get_object_or_404
from django.http import HttpResponse, Http404
from django.template import RequestContext, loader

from research.models import Journal, Encyclopedia_Chapter, Book

def research_index(request):
    latest_journal_list = Journal.objects.order_by('-pub_date')[:5]
    latest_chapter_list = Encyclopedia_Chapter.objects.order_by('-pub_date')[:5]

    context = {
        'latest_journal_list': latest_journal_list,
        'latest_chapter_list': latest_chapter_list
    }

    return render(request, 'research/index.html', context)

def journal_detail(request, journal_id):
    journal = get_object_or_404(Journal, pk=journal_id)
    return render(request, 'research/journal_detail.html', {'journal': journal})

def chapter_detail(request, chapter_id):
    chapter = get_object_or_404(Encyclopedia_Chapter, pk=chapter_id)
    return render(request, 'research/chapter_detail.html', {'chapter': chapter})

Здесь приложение url.py:

from django.conf.urls import patterns, url

from research import views

urlpatterns = patterns('',
    url(r'^$', views.research_index, name='research'),
    url(r'^(?P<journal_id>\d+)/$', views.journal_detail, name='journal_detail'),
    url(r'^(?P<chapter_id>\d+)/$', views.chapter_detail, name='chapter_detail'),
)

Вот шаблон index.html:

{% extends 'research/base.html' %}

{% block research_content %}

<div class="container">
    <div class="row featurette">
        <h3 id="research">Peer-reviewed Journal Articles</h3>
        {% if latest_journal_list %}
            <ul id="research">
            {% for journal in latest_journal_list %}
                <li id="research">
                            <img src="{{ journal.image.url }}" id="research">
                            <h4>{{ journal.journal }}</h4>
                            <h5>{{ journal.title }}</h5>
                            <a href="{% url 'research:journal_detail' journal.id %}">Read More</a>
                        </li>
            {% endfor %}
            </ul>
        {% else %}
            <p>No journals are available.</p>
        {% endif %}
    </div>

    <div class="row featurette">
        <h3 id="research">Encyclopedia Chapters</h3>
        {% if latest_chapter_list %}
            <ul id="research">
            {% for chapter in latest_chapter_list %}
                <li id="research">
                            <img src="{{ chapter.image.url }}" id="research">
                            <h4>{{ chapter.journal }}</h4>
                            <h5>{{ chapter.title }}</h5>
                            <a href="{% url 'research:chapter_detail' chapter.id %}">Read More</a>
                        </li>
            {% endfor %}
            </ul>
        {% else %}
            <p>No encyclopedia chapters are available.</p>
        {% endif %}
    </div>
</div>

{% endblock %}

На всякий случай это важно, вот мой cms_app.py:

from cms.app_base import CMSApp
from cms.apphook_pool import apphook_pool
from django.utils.translation import ugettext_lazy as _


class ResearchApp(CMSApp):
    name = _("Research App")
    urls = ["research.urls"]
    app_name = "research"

apphook_pool.register(ResearchApp)

Мысли? Любая помощь будет принята с благодарностью.
