Rails - Jul 2008 - Looking for a framework to report user feedback and form errors

We''re building our first Rails app and looking for a consistent way to
provide feedback messages; things like success messages like "your
password changed successfully" or form errors with the form field
highlighted in red (you know).

I''ve read that Rails provides a framework for this but we''ve
diverged
in how we do this in our app and would to reign things in :)

Thanks!

Welcome in Rails and Ruby. For your question, ruby on rails handles all 
error messages depending to your wanted. Example :

you want form errors with highlighted messages, rails handles it in 
model, you can see validates function with :messages => "...." or

def validate
...
errors.add(:attribute, "cant be bla..bla..bla")
end

But if you want show notificatin after input data like "your password 
changed successfully", you can use flash[:notice]

in your view just call :

<% if flash[:notice] -%>
<%= flash[:notice] %>
<% end %>

for hightlighted error messages, in your view is just calling :

<%= error_messages_for ''model_name_1'',
''mode_name_2'' %>


i hope my description can help your problem, good luck.
