Hi, Sorry for the mass questions, i tried to concentrate these so as not to flood the mailing list :) : *How do i add a column to an existing table and *how is the migration Google SOC is going along (where is the code). *How do i do validation in SQLAlchemy in the database and outside. For example: putting regular expressions to check if a field is valid. when saving, or assigning and when flush() called, run a test on all objects assigned to session. *Another more complex example, do an atLeastOne-To-one relationship, i.e., verify when saving a user to users_table that it at least have one address. *In the database, how can you add conditions, i.e. in users_table schema users_table.field_a>users_table.field_b (postgresql can do that) *Does SQLAlchemy have a mechanism to deal with Schema like in postgresql, i.e., namespaces? For example LABranch.users_table *Using ORM, are there any security problems in serializing (pickling) a User() object (of users_table) and sending it to a client from the server?
