My code worked fine when it was all in one file. Now, I'm splitting up classes into different modules. The modules have been given the same name as the classes. Perhaps this is a problem, because MainPage is failing when it is loaded. Does it think that I'm trying to inherit from a module? Can module/class namespace collisions happen?
MainPage.py
import BaseHandler
from models import Item
from Utils import render
class MainPage(BaseHandler):
def body(self, CSIN=None): ##UnusedVariable
self.header('Store')
items = Item.all().order('name').fetch(10)
render('Views/table.html', self, {'items': items})
self.footer()
BaseHandler.py

It appears this can be solved by using
from BaseHandler import BaseHandler
Is it bad style to have the module and class name be the same?
Yes, module names share the same namespace as everything else, and, yes, Python thinks you are trying to inherit from a module.
Change:
class MainPage(BaseHandler):
to:
class MainPage(BaseHandler.BaseHandler):
and you should be good to go. That way, you're saying "please inherit from the BaseHandler class in the BaseHandler module".
Alternately, you could change:
import BaseHandler
to:
from BaseHandler import BaseHandler
First of all the filenames should be all lowercase. That's Python convention that helps to avoid confusion such as this, at least most of the time.
Next, your import from withing MainHandler.py is wrong. You are importing BaseHandler (the module) and referencing it as if it were a class. The class is actually BaseHandler.BaseHandler. You need to reference it as such.
Try that and it should work for you.

I have a query in a model's method definition:
'content_type_id': ContentType.objects.get_for_model(model).pk,
https://github.com/seperman/django-tagging/blob/develop/tagging/models.py#L107
And it raises "App registry is not ready yet".
Putting the line inside another independent function doesn't help either since it still gets called.
Django docs:
Executing database queries with the ORM at import time in models
modules will also trigger this exception. The ORM cannot function
properly until all models are available.
How can I make it lazy evaluate this line?
I thought about caching its results manually in a file by making a management command. And then reading the cached result but there should be a much better/cleaner solution(?)

django-tagging is being a little inconsiderate here.
TagField is a descriptor, meaning if you access YourModel.tags, it runs code which executes a database query.
It just so happens that django-mptt iterates over all the attributes of your MPTTModel classes during startup (before the app cache has loaded), so it happens to trigger this exception.
I don't know how you'd prevent that in django-tagging while maintaining the API (YourModel.tags has to get tags from somewhere). Issues like this are probably the reason why django-tagging is no longer maintained.
However, I'm the maintainer of django-mptt and I've committed a workaround. If you upgrade to the master version of mptt you should find it works now.
You are calling _get_usage before the app has been registered. Wherever you are calling it needs to be changed to a point where the app has been configured. Basically, if you need a model at import time you should use ready().
For example, if you had a signals.py you could do:
# in apps.py
class SomeAppConfig(AppConfig):
def ready(self):
from . import signals
or in your case:
# in apps.py
class SomeAppConfig(AppConfig):
def ready(self):
mgr = TagManager()
mgr._get_usage(#some_args)
As the docs state: ready() ... is called as soon as the registry is fully populated
i've just approached Google App Engine. I've joined a project without having a clue about how it work so i'm sorry if this question looks dumb.
My problem is that looking at the log, it says it cannot import ndb. I've looked up for that a bit and discovered this should be present by default in version 1.6.4 of the google app engine.
I've tried to import it from console and it doesn't work either. My installation of python and google app engine are clean, i did both today.
What should i do?
I'm working on windows with python 2.7 and google app engine 1.6.4.
This is the line of code giving me problems:

You need to import it like this:
from google.appengine.ext import ndb
If you just say import ndb you are missing out on some import path information. Don't be afraid to copy the code that is having trouble into your question. Often, that will provide the vital clue.
UPDATE:
WTForms is not included as part of the AppEngine SDK. You'll need to install it on your system.
from wtforms.ext.appengine.ndb import model_form
can't work. wtforms does not have a ndb package.
it should be:
from wtforms.ext.appengine.db import model_form
I have post here about which I learned later that gae has moved here.
Basically I tried django-nonrel example, replacing its django with django-1.3.1 since I coded my app on it but it gives some basic error like cannot find django.db.utils. Note that I have created symbolic link from django -> Django-1.3.1/django and hope its not the issue.
Bases upon replies if I try to use django-nonrel version in my app similar to sample app I get error as below as if its cannot find sqlite3 backend though it mentions as one option in its choices. Also again utils.py is not found.

what version of django is compatible with django-nonrel or do I have to do development using django-nonrel instead of Django-1.3.1 ?
As I read more on django-nonrel I feel that there are few modification needed to django code. Its not straight forward to just use the project as it is. I need to create abstract model super class and it does not support manytomanyfield which I use in my project.
I guess some one confirm these restriction then probably I can close this thread.

Regards,

You can't just replace the version of Django in nonrel. It's actually a fork of Django, with a number of customizations.
Django-1.3.1/Django's database models do not work on Google App Engine.
Django-nonrel implements a backend so that Django models will work on Google App Engine.
So if you want to use Django models, you must use Django-nonrel. Otherwise, you can use Django for templating/forms, but you need to use Google App Engine's db.Model or ndb.Model based models.
I copied my httplib2 directory into my GAE project, and now I'm getting the following error:
line 64, in <module> _ssl_wrap_socket = ssl.wrap_socket
Is this an issue with Google App Engine, or did I somehow install my httplib2 incorrectly?

AttributeError: 'module' object has no attribute 'wrap_socket'
Still having this issue. About the only thing I can think of that could possibly be causing this is my machine running Python 2.7; Is it possible that is causing the issue?
As a workaround:
Can you use Google App Engine SDK 1.4.3 (this looks like a 1.5.0 regression).
Or force httplib2 fallback on httplib.FakeSocket with:
import sys
sys.modules['ssl'] = None
import httplib2
A new issue has been filled there:
http://code.google.com/p/googleappengine/issues/detail?id=5064
It looks already fixed in httplib2 side:
http://code.google.com/p/httplib2/source/detail?r=cf721c1693a68e9438899be3d78acccae6ab0e30#
The AppEngine sandbox doesn't allow access to a sockets API, for an http library to work on GAE it would have to wrap urllib (which in turn wraps the url_fetch API).
EDIT Looks like httplib2 should work so I guess you just need to ensure your paths are setup correctly.
See this question
This Blog claims to fix the GAE issues. I haven't tried it yet, but sounds right.
I must be doing something stupid. I'm running this in Google App Engine:
class MainHandler(webapp.RequestHandler):
def render(self, template_name, template_data):
path = os.path.join(os.path.dirname(__file__), 'static/templates/%s.html' % template_name)
self.response.out.write(template.render(path, template_data)) # error here
def get(self):
self.response.out.write("hi")
def main():
application = webapp.WSGIApplication([('/', MainHandler)],
debug=True)
util.run_wsgi_app(application)
if __name__ == '__main__':
main()
This gives an error:

NameError: name 'self' is not defined
What am I doing wrong?
The exception is happening while the class is being defined, which means that your indentation is off. Tabs in Python are equivalent to 8 spaces, so if all the preceding lines are using tabs and your tabstop is set to 4 spaces then the indentation only looks correct.
Just in case someone happens upon this and is looking for a solution not having to do with indentation, this is a good reference for how / when to use self.
NameError: name 'self' is not defined
Most style guides for python, including the google style guide, recommend you use spaces instead of tabs... most text editors support this too. Helps you avoid mistakes like this.
