Paginate trouble

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

Did you restart your server?

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.

When I change that it throws the error:

NameError in CommunityController#index

undefined local variable or method `spec’ for
#CommunityController:0xb6b0d504

It is confusing. because your ‘specs’ only can be accessed in controller
not in view. what is variable do you use for pagination? ‘specs’ or
@users’?

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]

I believe it is tied in with user.

This is the app/views/community/_user_table.rhtml file:

<% if @users and not @users.empty? %>

<% @users.each do |user| %> <% end %> <% if paginated? %> <% end %>
Name Age Gender Location
<%= link_to user.name, profile_for(user) %> <%= user.spec.age %> <%= user.spec.gender %> <%= user.spec.location %>
Pages: <%= pagination_links(@pages, :params => params) %>
<% end %>

If that helps answer your question.

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

Good LUcK,

Did you sort out this problem?
I’ve got the same error message!
