Hi list
First a brief disclaimer: I am still very new to rails and ruby both
[about 4 days to be exact] so please excuse me if this is an obvious
mistake. I thought I had got the use of validates... right until I tried
to use validates_uniqueness_of
My setup for testing: I have a simple users table in mysql with the
normal primary key ''id'' and a field
''username''
I include the line
validates_uniqueness_of :username, :message => ''That username is
already taken, please try again'' in the User class and try it out.
It does raise a validation message when I try and use an existing
username on either edit or new records but, and this is what has me
confused, it does it twice.
e.g. I get the error block at the top of the form using
<%= error_messages_for ''user'' %>
but it says there are two errors in the form and repeats the above error
message for both descriptions. Aside from that I only have the one
validation rule on this table at the moment.
Does anyone have any ideas what I may be doing wrong please or is this a
known problem. A quick scan through the list archives and I could not
see this covered [sorry if I missed an existing explanation]
Thanks
Huw
