[web2py:13642] Re: Indices/constraints and the DAL

[Timothy Farrell]

Fran what you're talking about is proper ON DELETE CASCADE functionality.  I've seen code to this effect in sql.py and it is mentioned on mentioned briefly on page 138 of the manual.  All you should have to do it setup your references appropriately. -tim Fran wrote: On Dec 16, 10:47 am, billf <billferr...@blueyonder.co.uk> wrote: Personally, I would vote to implement multi-column unique constraints so that data integrity can be specified completely using DAL syntax without the need for native SQL. I am at the stage of my app where I need to do a delete on an item which has records in many tables. I'd love a DAL-way of doing this without manually having to list each of the tables which may contain an associated record. (Since there's a large number of tables which could have such a record) I'm not sure what would be required to allow this?
