Well, the simplest solution is to change the form method to GET:
<form action = "{{=URL('operations')}}" method = "GET" >
That will put the "table" variable in the URL query string, where it will
persist. However, with this method, the search feature won't work because
it uses the query string and doesn't preserve the existing query string.
If you want to use the session instead, you could do something like this
(leaving the form method set to "POST" in this case):
def operations():
if request.post_vars and 'table' in request.post_vars:
session.operations_table = request.post_vars.table
if not session.operations_table:
redirect(URL('default', 'action_to_select_operations_table'))
grid = SQLFORM.grid(db[session.operations_table], user_signature=False)
return locals()
When the form first posts to the operations action, the table name will be
stored in the session. If someone tries to access the URL without the table
name being stored in the session, it will redirect to the form where the
table can be selected.
