Can't do a find_by_sql...returns '#'

Rails
1

Hello everyone, I’m trying to do a find_by_sql and every time my
results are only returned as a pound sign ‘#’. What does this mean?
Here is my query…

<%= Guestbook.find_by_sql “SELECT g.body from guestbooks g where
g.id=(SELECT max(g.id) from guestbooks g)” %>

I’m just trying to retrieve the last post in the guestbook to display
in a sidebar. No matter if I tried to calculate this in the Guestbook
model or in the view it returned #. I couldn’t even do a
Guestbook.find(:all). That just returned as many # signs as there were
db entries for the guestbooks table.

Any ideas?

Thanks,
-Jon

Generally the ‘#’ is generated when you try to print an object that
doesn’t know how to represent itself as a string.

Couple of pointers here.

try this…

<%= Guestbook.find(:first, :order=>‘id DESC’).body %>

This will print the body from the Guestbook entry with the highest id
number. Assuming that ‘body’ is a string or text column, it should
work fine.
