Will_paginate problem

Rails
1

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

RAILS_ROOT: C:/InstantRails-2.0-win_2/rails_apps/diligence

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)

rails (2.3.8, 2.0.2)

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

C:\InstantRails-2.0-win_2\rails_apps\pagination>gem list will_paginate

*** LOCAL GEMS ***

will_paginate (2.3.14)

C:\InstantRails-2.0-win_2\rails_apps\pagination>gem list ruby

I had made a fresh project of name “pagination”, table name is “lists”

  format.html # index.html.erb
  format.xml  { render :xml => @lists }
end

CODE in MODELS list.rb is below

class List < ActiveRecord::Base
cattr_reader :per_page
@@per_page = 2

end

CODE in VIEWS index.html.erb is below

Listing lists

<% @lists.each do |list| %>

<% end %>
Name Pin
<%=h list.name %> <%=h list.pin %> <%= link_to 'Show', list %> <%= link_to 'Edit', edit_list_path(list) %> <%= link_to 'Destroy', list, :confirm => 'Are you sure?', :method => :delete %>

<%= will_paginate @lists%>

<%= link_to ‘New list’, new_list_path %>

i had added in ENVIRNMENT.RB file

require ‘will_paginate’

C:\InstantRails-2.0-win_2\rails_apps\pagination>ruby script/server
=> Booting Mongrel
=> Rails 2.3.8 application starting on http://0.0.0.0:3000

require is now out of obsolete, Instead use

config.gem ‘will_paginate’

in environment.rb inside the Initializer block.
