I didn't explain myself correctly. The SQLFORM.grid does not check for record changed during the edit. Which is a shame and I requested this feature in Github.
To overcome this limitation, I want to compare the selected row from the grid (when pressing the edit button) with the current record on disk. And I want to do this from inside the onvalidation function, because that is the only way to check before the edited record is saved. At least that I know of. The callbacks you mentioned don't seem to help with this. Or am I missing something? segunda-feira, 25 de Março de 2019 às 20:34:50 UTC, Dave S escreveu: > > > > On Monday, March 25, 2019 at 7:25:26 AM UTC-7, João Matos wrote: >> >> Hello, >> >> How can I access the rows that resulted from the query made by the >> SQLFORM.grid from the onvalidation function? >> >> Thanks, >> >> JM >> > > I don't think you can, because the function is called before the select() > or write() (but after the check for IN_DB()). > You are passed the form data. > > You may want instead the db callbacks: > <URL: > http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#callbacks-on-record-insert-delete-and-update > > > > /dps > > -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
