Hello,
I am trying to display a Field that has type 'blob' in a SQLFORM.grid. The
data is NOT user-uploaded, thus I cannot use the typical uploadfield +
request.download pattern. I am using blob because I need to store important
algorithm-generated data that is too large to fit in the 'text' field type.
I would like it to display a link to a handler.
I tried a simple test case model
db.define_table('blob_test',
Field('blob_field', 'blob', readable=True,
represent=lambda value, row: A('link',
_href=URL('handler', args=[row.id]))
)
)
#and in the controller:
def blob_grid():
response.view = 'generic.html'
grid = SQLFORM.grid(db.blob_test.id > 0)
return dict(grid=grid)
The result is that the controller does not display the link, and indeed the
entire column is overtaken by the default view/edit/delete buttons provided by
grid.

Interestingly, the appadmin display of the table does have the represent link
as intended.

How can I have this representation work for SQLFORM.grid? Thanks.
