Error_messages_for?

Rails
1

Hi,

I can’t list error_messages in my Form ??, and all the formfields are
reset …(I think my redirect :back clean everything, formfield and
error_messages …), only my flash[:notice] is ok…

I would like to use the “error_messages_for” tag to add a simple red *
on my textfiled if a problem occurs …

thanks for help

here are the basics steps to check that password and confirm_password
are equal:

a form:

<%= form_tag :controller => “contact”, :action => “addClient” %>
<%= error_messages_for ‘client’ %>
…

<%= text_field "client", "login",:size => 10 %> <%= password_field "client", "password",:size => 10 %> <%= password_field "client", "confirm_password",:size => 10 %> ...

controller:

@client=Person.new(params)
if (@client.save)
redirect_to :action => “index”
else
flash[:notice] = “pb during registration !”
redirect_to :back
end

model:

I just define a validate method
def validate
errors.add(:password, “different password ! try again”) unless
:confirm_password == :password
end

Arnaud,

Yes the error messages are lost with redirect_to :back. Perhaps you
really want to just re-render the form. From your post, I don’t know
what action initially renders the form but if it is the
“renders_my_form_with_password” action in the same controller then
instead of redirect_to :back do

render :action=>‘renders_my_form_with_password’
