Props to Richard Vezina for posting a similar technique. This is
built on his post
>From the book we know that, "Components' objects can be referenced via
their position, and helpers act as lists with respect to their
components."
A little archaeology in the source code tells us that SQLFORM.grid
emits a DIV object. When there's an index table involved, the DIV has
three components: a DIV, a DIV containing a TABLE and another DIV.
# first we get the grid
grid = SQLFORM.grid(query)
# examine the div at the top of the grid div
# for index lists, this div is of the class 'console',
# so look for 'console' near the start of the div
# there is CERTAINLY a better way to detect an index table, but
this works
if 'console' in str(grid[0])[0:35]:
## grid[1][0][1] is the DIV, TABLE and TBODY
## so we iterate over TRs in the table body
for row in grid[1][0][1]:
## TR acts like a list, so we use some Python list fu
row.insert(-1, 'foo')
return dict(grid=grid)
Done. Haven't cleaned up the table head yet, but it should be
similar.
