I can’t figure out how to use the pagination with an existing array of objects got from has_many associations. So, I have Enterprise model and Service model. Enterprise has_many :services. I’d like to show services for every enterprise; In my ServicesController in index action I do:
before_filter : find_client
def index
@services = @client.services
end

private
def find_client
@client = Client.find(:client_id)
end
How is it possible? If try to use like that:
@services = @client.services.paginate :page => params[:page], rder => ‘created_at’, :per_page => 20

I get:

NoMethodError in Enterprises#show

Showing app/views/enterprises/show.html.erb where line #21 raised:

undefined method `total_pages’ for #

Extracted source (around line #21):

18: “/services/service”,
19: :collection => @enterprise.services, :locals=> {:client => @enterprise} %>
20:

hey guys, nice post. i using rails to build a client which only consumes restful webservice with activeresource, so i deactivated activerecord. i’m getting an array of activeresource object limited by :page and :per_page an so on. if i try to call will_paginate @results in the view it gives me an NoMethodError. In the controller i’m using that WillPaginate::Collection.create(…) and it doesn’t complain. but if i activate activerecord everything works. how can i say will_paginate not to be dependent on activerecord do i really have to patch it myself?

Found it:

http://mislav.uniqpath.com/static/will_paginate/doc/

2.2.0, released 2008-04-07 API changes

Remove old, deprecated style of calling Array#paginate as “paginate(page, per_page)”.

If you want to specify :page, :per_page or :total_entries, use a parameter hash.

Am I the only one getting the exception: Wrong number of arguments (2 for 1) trying this:

@page_results = @posts.paginate(params[:current_page], params[:per_page])

Thanks!
