Hi, I have a sqlform with four tabs. There is a main form and 4 additional
tabs. In each tab there is one grid with a related table to the one in the
main form (1 to many relationship), and they are loaded gracefully using
the LOAD function and ajax.
In my first version, I used a separate function/view for each grid, they
are called by every LOAD command, and everything worked fine.
The next time I needed something like that, I thought that writing 4
functions/views for the grids was too redundant as each function was quite
similar to the other, and I only needed to change a few parameters (table
name, related field) and decided to create a single function with the
corresponding parameters to show the corresponding table in each tab/grid.
Everything seemed to work fine, but in my tests, I noticed that when I
created a new record in one of those tabs, and there was an automatic
reload of the grid (in grid mode), it always displayed the last grid loaded
in the initial load of the tabs. Pushing F5 and forcing an initial reload
of the multi-tabbed form, forced every grid to display properly.
Digging into SQLFORM.grid, I noticed a line:
referrer = session.get('_web2py_grid_referrer_' + formname, url())
That could explain why I'm always getting the last grid loaded in the
initial load of the multitabbed form. I would like to confirm this and ask
you if there would be any workaround not dependent on a session variable,
that for sure will cause concurrency issues.
Best regards and thankyou for this helpful group.
