Well, I added will_paginate to my application. Though when I attempt to
use I get an action controller error.
here is the app/controller/community_controller file I created:
class CommunityController < ApplicationController
helper :profile
def index
@title = "Community"
@letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".split("")
if params[:id]
@initial = params[:id]
@pages, specs = paginate(:specs,
:conditions => ["last_name LIKE ?",
@initial+"%"],
:order => "last_name, first_name")
@users = specs.collect { |spec| spec.user }
end
end
def browse
end
def search
if params[:q]
query = params[:q]
# First find the user hits...
@users = User.find_by_contents(query, :limit => :all)
# ...then the subhits.
specs = Spec.find_by_contents(query, :limit => :all)
faqs = Faq.find_by_contents(query, :limit => :all)
# Now combine into one list of distinct users sorted by last name.
hits = specs + faqs
@users.concat(hits.collect { |hit| hit.user }).uniq!
# Sort by last name (requires a spec for each user).
@users.each { |user| user.spec ||= Spec.new }
@users = @users.sort_by { |user| user.spec.last_name }
end
end
end
The message is:
NoMethodError in CommunityController#index
undefined method `paginate'' for #<CommunityController:0xb6bd4ba4>

Hello, I''m still new to Rails, but installed will_paginate yesterday with no problems. I believe pagination is a method from your model, not the controller. Thus @pages, specs = paginate(:specs, should become @pages, specs = Community.paginate(:specs, or whatever the model is. Hope this helps.

''specs'' or ''@users''? Kieran P wrote:> > @pages, specs = Community.paginate(:specs,you can not use it because :specs is different table name than of community. @pages, @specs = Spec.paginate :conditions => ["last_name LIKE ?", @initial+"%"], :order => "last_name, first_name", :page => params[:page] Reinhart http://teapoci.blogspot.com -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

hmmm.... now i understand what you want to do.
yes, of course your way is wrong. Try it :
@spec = Spec.find(:all, :conditions => ["last_name LIKE
?",@initial+"%"], :order => "last_name, first_name")
@user_collection = @spec.collect { |spec| spec.user }
@pages, @users = @user_collection.paginate :page => params[:page]
I read here:
http://github.com/mislav/will_paginate/tree/master/lib/will_paginate
This will_paginate support Array and Collection pagination or update
your pagination or copy those file to your
vendor\plugins\will_paginate\lib\will_paginate
or read it : http://www.devchix.com/2007/07/23/will_paginate-array/

I have solution with regular pagination (not will_paginate)
@spec = Spec.find(:all, :conditions => ["last_name LIKE
?",@initial+"%"], :order => "last_name, first_name")
@user_collection = @spec.collect { |spec| spec.user }
@pages, @users = paginate_collection @user_collection, :page =>
@params[:page]
private
def paginate_collection(collection, options = {})
default_options = {:per_page => 10, :page => 1}
options = default_options.merge options
pages = Paginator.new self, collection.size, options[:per_page],
options[:page]
first = pages.current.offset
last = [first + options[:per_page], collection.size].min
slice = collection[first...last]
return [pages, slice]
end
