    <p>First, I would suggest you have a look at "<a href="http://sites.google.com/site/io/rapid-development-with-python-django-and-google-app-engine" rel="noreferrer">Rapid Development with Python, Django, and Google App Engine</a>"</p> <p>GvR describes a general/standard project layout on page 10 of his <a href="http://sites.google.com/site/io/rapid-development-with-python-django-and-google-app-engine/rapid_development_with_django_gae.pdf?attredirects=0" rel="noreferrer">slide presentation</a>. </p> <p>Here I'll post a slightly modified version of the layout/structure from that page. I pretty much follow this pattern myself. You also mentioned you had trouble with packages. Just make sure each of your sub folders has an __init__.py file. It's ok if its empty.</p> <h2>Boilerplate files</h2> <ul> <li>These hardly vary between projects</li> <li>app.yaml: direct all non-static requests to main.py </li> <li>main.py: initialize app and send it all requests </li> </ul> <h2>Project lay-out</h2> <ul> <li>static/*: static files; served directly by App Engine</li> <li>myapp/*.py: app-specific python code <ul> <li>views.py, models.py, tests.py, __init__.py, and more</li> </ul></li> <li>templates/*.html: templates (or myapp/templates/*.html)</li> </ul> <p>Here are some code examples that may help as well:</p> <h2>main.py</h2> <pre><code>import wsgiref.handlers from google.appengine.ext import webapp from myapp.views import * application = webapp.WSGIApplication([ ('/', IndexHandler), ('/foo', FooHandler) ], debug=True) def main(): wsgiref.handlers.CGIHandler().run(application) </code></pre> <h2>myapp/views.py</h2> <pre><code>import os import datetime import logging import time from google.appengine.api import urlfetch from google.appengine.ext.webapp import template from google.appengine.api import users from google.appengine.ext import webapp from models import * class IndexHandler(webapp.RequestHandler): def get(self): date = "foo" # Do some processing template_values = {'data': data } path = os.path.join(os.path.dirname(__file__) + '/../templates/', 'main.html') self.response.out.write(template.render(path, template_values)) class FooHandler(webapp.RequestHandler): def get(self): #logging.debug("start of handler") </code></pre> <h2>myapp/models.py</h2> <pre><code>from google.appengine.ext import db class SampleModel(db.Model): </code></pre> <p>I think this layout works great for new and relatively small to medium projects. For larger projects I would suggest breaking up the views and models to have their own sub-folders with something like:</p> <h2>Project lay-out</h2> <ul> <li>static/: static files; served directly by App Engine <ul> <li>js/*.js</li> <li>images/*.gif|png|jpg</li> <li>css/*.css</li> </ul></li> <li>myapp/: app structure <ul> <li>models/*.py</li> <li>views/*.py</li> <li>tests/*.py</li> <li>templates/*.html: templates</li> </ul></li> </ul>

    1. COOnce you get to 20 or 30 views, and a couple "views" that just handle posts and then redirect, do you break them out into separate files? Perhaps in myapp/views/view1.py, myapp/views/view2.py? Or that just my Java/C# background showing through?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
