Getting Started with Tastypie: no such table: myapp_entry

Just like the title of the page says, I'm Getting Started with Tastypie by following the linked tutorial. But when I try to load

, I get HTTP 500 response, with this error message:

no such table: myapp_entry

When I look in sqlite3, indeed, there's no such table.

Here's how I followed the tutorial:

$ django-admin startproject mysite
$ cd mysite
$ django-admin startapp myapp

I created/edited
as specified in the tutorial, and added 'tastypie' to my

Note: It wasn't clear to me which
file to edit or create, so I edited the existing one in
. So now it looks like this:

from django.conf.urls import url, include
from myapp.api import EntryResource
from django.contrib import admin

entry_resource = EntryResource()

urlpatterns = [
url(r'^admin/', admin.site.urls),
# url(r'^blog/', include('myapp.urls')),
url(r'^api/', include(entry_resource.urls)),

I commented out the 'blog' line, because it caused the error ImportError: No module named 'myapp.urls'. I think this is the step I'm stuffing up, but when I tried putting the tutorial code in
instead, I got a 404 when I tried loading the page, and when I then tried adding
url(r'^blog/', include('myapp.urls'))
, I got a stack overflow. So I've gone back to the code as shown above.

To be clear, here's what my file structure looks like now:

$ find . -type f -not -name '*.pyc'

The one other change I made was adding a
subclass to my
class, so the first dozen lines look like this:

class Entry(models.Model):
user = models.ForeignKey(User)
pub_date = models.DateTimeField(default=now)
title = models.CharField(max_length=200)
slug = models.SlugField(null=True, blank=True)
body = models.TextField()

class Meta:
app_label = 'myapp'

# __unicode__() and save() as in the tutorial

If I don't do that, I get this in the console: RuntimeError: Model class myapp.models.Entry doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

Another thing I tried was
python manage.py migrate
. It found things to do, but this hasn't fixed this error.

Here's what I've got installed (in

  • Django (1.10)

  • django-tastypie (0.13.3)

  • PyYAML (3.12)

  • mysqlclient (1.3.10) (although I haven't actually set it up yet—I'm using the default sqlite3 setup for now)

I'm running Python 3.4.3, but I got exactly the same error using a quite similar setup in Python 2.7.6.

Finally, here's the full stack trace from that HTTP 500 page:

{"error_message": "no such table: myapp_entry", "traceback": "Traceback (most recent call last):

The above exception was the direct cause of the following exception:

Can anybody see what I'm doing wrong? Or does the tutorial not apply to these versions?

Answer Source

sqlite3.OperationalError: no such table: myapp_entry

For one, your project is using sqlite, not mysql. You should update your DATABASES setting.

Add myapp to your INSTALLED_APPS in your project settings.

Then, run ./manage.py migrate. After fixing INSTALLED_APPS Django should be able to find the app's Entry model and create the table for it.
