[PonyORM-list] Entity's modifications

[Vincent LE GOFF]

Hi everyone,

I'm eager to begin working with Pony ORM.  That sounds so simple 
compared to other ORMs I've seen.  However, I have a concern regarding 
entity's evolution.

I didn't see an automatic way to handle these type of modifications.  
For instance, what happens if we work with an entity, then decide to add 
a new field to it?  Or to change the type of a given field?  Or to 
remove one?  Performing specific updatess (called migrations in other 
ORMs) can be sometimes useful, too.  For instance, if we want to delete 
two fields but combining their old results in a single one.  Is there 
any way to do that using Pony ORM?

Thank you very much for your answer!

Happy hacking,

Vincent
