I am starting to play with validations as I want to catch errors before
SQL rejects inserts to the table which are ugly when nulls are sent to
''Not Null'' columns, etc.
If I do something in my model like...
validates_format_of :first_name,
:with => /^\w+$/,
:message => "you moron, enter a name"
I still end up getting the trace window and not the output in the form
itself where I would expect it to display with a first line that reads:
<%= error_messages_for ''client'' %>
>From Agile book and from rails.rubyonrails.com, I can see that I can use
rescue_action_in_public(exception) but that seems to be for trapping
against not found pages.
How do I capture these errors and stay within my form and display my
'':message'' there?

Are you redirecting at the end of the action that would have the validation
error? That
tripped me up for a while.
I finally wound up putting the model object in the flash if there were errors.
In my
"add_comment" action, I have:
if @comment.save
flash[:notice] = ''Comment added.''
else
flash[:comment] = @comment
end
redirect_to :action => ''show'', :id => @proposal
And then I have to do this in the view:
<% @comment = @flash[:comment]
if(not @comment.nil?)
%>
<%= error_messages_for(:comment)%>
<% end %>
which seems annoying. I want to always redirect so that I never get the
form''s action url
let in the browser address bar.
Now, this may not actually be your problem and there could quite easily be a
cleaner
solution to this. But hopefully I''ll be right about the redirect and
that''ll at least get
you somewhere!

I''ve been having exactly the same problem, this works for me. There must be a cleaner way of doing this, but I''m over my blocker now so thanks! Mat.
