I created a view as you suggested. However, when I ran the view in
SQLForm.grid() I received a web2py error that the 'id' did not exist (which
is doesn't). As a hack to get around this, I manually created a column
named 'id' and hard-coded the value to '1' because my grid is display only
and no actions can be performed. This required an alias in my SQL, so I
gave it an alias exactly matching the name of the view. That was more
creative than I wanted to get but it works.
