Hello, I am trying to reflect the example from http://hg.sqlalchemy.org/sqlalchemy/file/04c17c7d88d6/examples/association/basic_association.py but with my own data structures.
I want to manage nutrients, nutrient values and nutrition lists. Therefore I have created a custom data type "weight" which helps me doing calculations with weights in different units. The relation between nutrients and nutrition lists is m:n, one list can have many nutrients and nutrients can be in many lists. The association table (nutrition values) stores the amount of a nutrient associated to one list. I think I got things working mostly, but flushing my data to the database breaks the program: http://paste.pocoo.org/show/253961/ >From what I understand from the message, there seems to be a problem with my custom data type. Maybe someone with more skill in sqlalchemy than me can shed some light on the matter ... Here's the full script http://paste.pocoo.org/show/253956/ Many thanks Frank -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
