[Modeling-users] howto manage messy db updates

[Mario R. <ma...@ru...>]

Hi,

how do people handle updating an existing database (with
data) for changes in the model? The py code aspect is OK,
but how is the db updated? Does one have to mess around
in SQL on a change case-by-case basis, or is there a way to
"automate" this more? Such as a modeling-based script to
populate a completely new db (with new model) from the old
db? Assuming the model plays nicely, letting the framework
auto-handle all pk values and relationships, is such a tool
possible?
