    <p>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 <code>MainPage</code> is failing when it is loaded. Does it think that I'm trying to inherit from a module? Can module/class namespace collisions happen?</p> <p><strong>MainPage.py</strong></p> <pre><code>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() </code></pre> <p><strong>BaseHandler.py</strong></p> <pre><code>from google.appengine.ext import webapp from google.appengine.api import users from Utils import * # Controller class BaseHandler(webapp.RequestHandler): # ... continues ... </code></pre> <p><strong>Failure Traceback:</strong></p> <pre><code>Traceback (most recent call last): File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 3180, in _HandleRequest self._Dispatch(dispatcher, self.rfile, outfile, env_dict) File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 3123, in _Dispatch base_env_dict=env_dict) File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 515, in Dispatch base_env_dict=base_env_dict) File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 2382, in Dispatch self._module_dict) File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 2292, in ExecuteCGI reset_modules = exec_script(handler_path, cgi_path, hook) File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 2188, in ExecuteOrImportScript exec module_code in script_module.__dict__ File "C:\Users\odp\workspace\Store\src\Main.py", line 5, in &lt;module&gt; import MainPage File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 1267, in Decorate return func(self, *args, **kwargs) File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 1917, in load_module return self.FindAndLoadModule(submodule, fullname, search_path) File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 1267, in Decorate return func(self, *args, **kwargs) File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 1819, in FindAndLoadModule description) File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 1267, in Decorate return func(self, *args, **kwargs) File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 1770, in LoadModuleRestricted description) File "C:\Users\odp\workspace\Store\src\MainPage.py", line 10, in &lt;module&gt; class MainPage(BaseHandler): TypeError: Error when calling the metaclass bases module.__init__() takes at most 2 arguments (3 given) </code></pre> <p><strong>UPDATE</strong> I appear to have solved it. This import works much better:</p> <pre><code>from BaseHandler import BaseHandler </code></pre> <p>Is it bad style to have the module and class name be the same?</p>

    1. COIt's not bad style to have the module and class name be the same so long as the casing is distinct. In Python it is convention to have module names be all lower case, and class names to be CamelCase. I suggest you read the Python Style Guide (PEP 8) - http://www.python.org/dev/peps/pep-0008/. It is immensely helpful!

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.

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