I have made this for my project and I do not see why you are using Openlayers
for this.
This has nothing to do with sqlalchemy.
off topic: Ext.form.Panel has no 'protocol' so I think you should extend
FormPanel to include that functionality. Ext.direct is the way to go for stuff
like this.
since 4.x is so much
better (consistant) , faster and more stable, I guess GeoExt is over a year
behind reality. If you use that try if you can wait for GeoExt2

Hi,
I am use to setup the collation in MySQL to ci_utf8 (Case Insensitive)
I would like the same behaviour on PostgreSQL.
I use Unicode (Or UnicodeText) as columntype
If I leave the Collation empty it defaults to C which means it looks at
bytecodes so it will NOT be case insensitive.
That is not going to work.
let me explain:
Polymorphic inheritance uses tables and discriminators and some logic somewhere
in the system. (As far as I can tell both SA and databases can do the job, i
have to look into that)
For each object there will be a table, including the base object.

Assuming you're talking about when the ORM establishes an instance from a
newly fetched row, you can use
to their needs. I find that the deeper I dive into SA, the
less examples are available, the harder it is to test functionality and
sometimes documentation gets more sparse.
