Thanks for the reply Michael!

I guess I have to do some coding, rather than trying to piece together other people’s work!

But I think I am understanding how to achieve some results with .invalid, based on your example. Needless to say, I’m new to CSS as well…

Thanks again!

Olia, displaying an error message is something you have to code yourself. There are just too many ways to do this and too many complications that I did not have a general solution when I wrote the validator script more than three years ago.

What you can get easily is some CSS styling for fields that have errors. See the example above.

You might be better off with another solution, however, none of the other validator scripts that I ever was aware of do everything you would want them to.

Hi Michael,
thank you for the plugin! I got it working as you described — the submit button is disabled if the form is invalid. But I am not sure how to make it display the appropriate error messages as the user types. I must be missing something basic, I am new to this, please advise!

thank you,
Olia

I’d have to see the place where stringify_keys! is called originally. There’s one place in my code (#add_class_name!) and although I don’t see how it might lead to an infinite recursion, you may try to comment it out.

I’ve just uploaded a new version fixing another problem with Rails 2.2.2 to Rubyforge, so please update your version before trying anything else.

Hi Michael, the instructions seemed st-fwd, however, I get the error on console while trying to fetch the page: Is there an issue with Rails/ActiveRecord2.2.2?

ActionView::TemplateError (stack level too deep) on line #23 of app/views/………rhtml:
23: 36, :class => ‘text’ %>

/Library/Ruby/Gems/1.8/gems/activesupport-2.2.2/lib/active_support/core_ext/hash/keys.rb:16:in `stringify_keys!’
/Library/Ruby/Gems/1.8/gems/activesupport-2.2.2/lib/active_support/core_ext/hash/keys.rb:15:in `each’
/Library/Ruby/Gems/1.8/gems/activesupport-2.2.2/lib/active_support/core_ext/hash/keys.rb:15:in `stringify_keys!’
…..

I get the error with or without adding html => {:class => ‘validated’} in form_for.
Any clue?

Wilton, I have no idea why RAILS_ROOT might not be defined in your case. I just created a fresh Rails 2.1 project (on Linux) and then

script/plugin install  svn://rubyforge.org/var/svn/clientsidevali/client_side_validation/trunk

and it worked.

Jose, if Form.Validator has no properties, than validator.js is not loaded from your page. Either the necessary script tag is missing or the script it refers to is not installed at the correct location.
