Greetings, I would like to reference a model in another database. I see that the TODO list on MultipleDatabaseSupport in the code wiki has the following:
When validating models, warn user if a model references another model that is configured to use a different connection DONE I started this post to request help understanding why that would be a problem, but the process of composing this email made me focus on the question and come of with an answer. Now it seems kind of silly that it was a question, but I was trying to refactor my applicatio with the multiple-db-support. I'm going to go ahead and post this with my answer in case someone else has the same desire to reference a model in another database. Feel free to comment or not. Question: Why can't I reference a model in another database? Answer: The first database cannot maintain referential integrity with another database. It does not know how to connect to another database to ensure integrity is kept. So how do I do it? Business logic. First, have the one model keeps a reference to the primary key of the model in the other database. Second, ensure that the view takes care of the logic to create, update and delete the data using information from both databases. Thanks for helping me figure this out. ;-) Carlos Hanson --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
