    <p>I'm having problems with Webapp2. When I put handlers for URLs that point to different python files in the app.yaml I get the following error:</p> <pre><code>ERROR 2012-10-06 16:44:57,759 wsgi.py:203] Traceback (most recent call last): File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/runtime/wsgi.py", line 195, in Handle handler = _config_handle.add_wsgi_middleware(self._LoadHandler()) File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/runtime/wsgi.py", line 250, in _LoadHandler __import__(cumulative_path) ImportError: No module named application </code></pre> <p>My app.yaml:</p> <pre><code>application: [[app's name]] version: 1 runtime: python27 api_version: 1 threadsafe: yes inbound_services: - mail handlers: - url: /send script: email.application - url: /_ah/mail/update@sitdown-standup.appspotmail.com.* script: email.application - url: /.* script: SDSUmodels.application libraries: - name: webapp2 version: "2.5.1" </code></pre> <p>SDSUmodels.py ends with:</p> <pre><code>application = webapp2.WSGIApplication([('/info', MakeBasicInfo)], debug=True)` </code></pre> <p>and email.py ends with:</p> <pre><code>application = webapp2.WSGIApplication([('/request', Request_update), ('/send', Send_report), (Receive_email.mapping())], debug=True)` </code></pre> <p>When I remove these lines</p> <pre><code>- url: /send script: email.application </code></pre> <p>from app.yaml, the error stops, but this leaves me without a way to point a URL towards a particular file.</p> <p>I can see some alternative ways of handling this in <a href="https://stackoverflow.com/questions/11181957/how-to-organise-files-with-python27-app-engine-webapp2-framework">this question</a> but I was wondering why this approach isn't working. I've done this previously with the old webapp version in a different project and it's worked – details below.</p> <p>app.yaml:</p> <pre><code>application: [[other app's name]] version: 1 runtime: python api_version: 1 handlers: - url: /stylesheets static_dir: stylesheets - url: /twitter script: twitter.py - url: /_ah/mail/kindle@shelvdtracker.appspotmail.com.* script: kindle.py - url: /.* script: web.py inbound_services: - mail </code></pre> <p>twitter.py ends with:</p> <pre><code>application = webapp.WSGIApplication( [('/twitter', Process_new_DM)], debug=True) def main(): run_wsgi_app(application) if __name__ == "__main__": main() </code></pre>

    1. COThere is a stdlib library named [`email`](http://docs.python.org/library/email.html) already; perhaps you need to rename yours to prevent the wrong library being loaded?

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).
