Hi,
Not sure if there is anybody else using it or trying it, but I
encounter this as a start, and hanged there for some time.
In order to help starter going easier, it'd be better to correct it.
Because SQLFORM class can not be modified, then just to correct the example
in the book.
I think the simple way is to change in display_form function:
FROM:
link = URL('list_records', args='db')
TO:
link = URL('list_records')
in list_records, strip the first prefix by dot-delimit:
like:
query = request.vars.query
To:
query = request.vars.query
query = ".".join(query.split(".")[1:])
I tried it work.
