Rails 3: "uninitialized constant Formtastic::FormBuilder" error after deploying app on production server

I am trying to deploy my Rails3.0 application on production server. There was many troubles before, but all of them solved. And now I have another.

There is a passenger error page's text:

Error message: uninitialized constant Formtastic::FormBuilder

Exception class: NameError

Backtrace:

0 /home/ubuntu/.rvm/gems/ruby-1.9.2-p180@rails3.0/gems/client_side_validations-3.1.0/lib/client_side_validations/formtastic.rb 20 in `'

...

Google search results not helped me, and now I am here.

UPD: Also if i try to run WEBrick server there was the same error.

UPD: I try to comment "gem 'client_side_validation'" line in Gemfile, and error is disappeared. But now i cant use this gem.

I experience the same issue but not on the production, i got this error in the development after doing a:

bundle update

and then try to run my rspecs.

It seems that bundle update, installed client_side_validations 3.1.0 which seems to make problems ( ... not sure why, I don't have the time to analyze it atm), however using a fixed version in the Gemfile solved it:

gem 'client_side_validations', '3.0.5' 

hope it helps!

This happening because you have Formtastic 1.x installed. The 3.1.x version of ClientSideValidations expects Formtastic 2.

---

Check if you have formtastic gem installed.

Also run this on production machine

bundle install --deployment

As this will install all the gems to location which passenger can find. Sometimes, it happens that passenger can't find the gem paths.

---

I don't know if you have follow this process but i recomand you to wrap your passenger with your gemset and start with RVM for independent passenger mode

rvm wrapper ruby-1.9.2-p180@rails3.0 passenger

and for start for example like this :

rvm_path=$HOME/.rvm/ $HOME/.rvm/bin/rvm-shell '1.9.2-p180@rails3.0' -c \
    'cd /<your app PATH>/current/ && bundle exec passenger start -a 127.0.0.1 -p 3000 -d
