Hi

I am using rails 2.3.8 & ruby 1.3.7 & will_paginate 2.3.14

I have table name books. I am doing this code for pagination,

In book_controller

@@@@books = Book.paginate :page => params[:page], :per_page => 10@@@@

& in index.html.erb

@@@@@<%= will_paginate @books %>@@@@@

Also added in environment.rb file this line

@@@@@ require ‘will_paginate’@@@@@

After adding this when I am running “””ruby script/server””” then this error is coming

@@@@@ NoMethodError in StoreController#index

undefined method `paginate' for #<Class:0x4aaf448>

gem install will_paginate try again

I had install “will_paginate 2.3.14”

4

You're not - the stack traces show you are running rails 2.0.2, which may be part of the problem (eg config.gem was only added in 2.1)

You have both versions installed, which is ok. Have a look in config/environment.rb and you will find a line something like RAILS_GEM_VERSION = '2.3.8' unless defined? RAILS_GEM_VERSION If that does not say 2.3.8 then change it to that and, in ruby console do

rake rails:update

This will update the boot and so on to the latest version. Make sure that you have committed your source to your version control system (git or whatever) first so that you can see what has been changed.

Please don't top post, insert your reply at the appropriate place in the previous post. Another reader looking that this thread will ask what instructions you followed, if you had inserted your reply after my suggestions it would have been obvious.

Google can be very useful for this sort of problem. I googled for undefined method cache_template_extensions and the first link was for this error occurring after an upgrade. The solution for him was to remove the line from config/environment/development.rb

[...]

i had added in ENVIRNMENT.RB file

require 'will_paginate'

require is now out of obsolete, Instead use

  config.gem 'will_paginate'

in environment.rb inside the Initializer block.
