    <p>I have post <a href="https://groups.google.com/forum/#!topic/google-appengine-python/zi_4jVcPxUo" rel="nofollow">here</a> about which I learned later that gae has moved here.</p> <p>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.</p> <p>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.</p> <p>--> --> --></p> <pre><code>Traceback (most recent call last): File "c:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 4143, in _HandleRequest self._Dispatch(dispatcher, self.rfile, outfile, env_dict) File "c:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 4049, in _Dispatch base_env_dict=env_dict) File "c:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 616, in Dispatch base_env_dict=base_env_dict) File "c:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 3120, in Dispatch self._module_dict) File "c:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 3024, 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 2887, in ExecuteOrImportScript exec module_code in script_module.__dict__ File "I:\learn\python\event\djangoappengine\main\main.py", line 97, in &lt;module&gt;

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. </p> <p>I guess some one confirm these restriction then probably I can close this thread.</p> <h2>March 28</h2> <p>I removed M2M from my app. It was very minor thing just commented out M2M field.

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).
