No, it would only apply to the particular id field (not all id fields), and
since you can set the 'represent' attribute anywhere, you can do this only
for the particular SQLTABLE if desired. For example, in the controller that
creates the SQLTABLE:
def show_table():
db.mytable.id.represent = lambda id, row: etc.
table = SQLTABLE(...)
return dict(table=table)
This change doesn't affect requests for other functions -- it will only
take affect when this particular SQLTABLE is created. If you happen to need
a different 'represent' within the same action, you can simply redefine
db.mytable.id.represent as needed.
Note, this method is even more flexible than allowing linkto to return a
tuple, because it allows you to return any arbitrary output, including a
button element, or a link with special classes, or an onclick handler, etc.
