will_paginate gem problem

So I'm trying to use will_paginate-rails3 and its not working out here's what I have in my controller:

  def index
    @posts = Post.paginate(:page => params[:page], :per_page => 2 )

    respond_to do |format|
    format.html # index.html.erb
    format.xml  { render :xml => @posts }
  end
end

Gemfile: gem "will_paginate-rails3", '~> 3.0.pre'

posts/index.html.erb: <%= will_paginate @posts %>

NoMethodError: NoMethodError (undefined method `paginate' for #<Class:0x12c3438>):
  app/controllers/posts_controller.rb:5:in `index'

Rendered C:/Ruby/lib/ruby/gems/1.9.1/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/_trace.erb (0.0ms)
Rendered C:/Ruby/lib/ruby/gems/1.9.1/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (0.0ms)
Rendered C:/Ruby/lib/ruby/gems/1.9.1/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (15.6ms)

Bundle install says the gem is there:

Anybody know where I made my mistake? Thanks,

Matt

Try to delete the "all". I had the same problem, since I deleted the "all", it works now. My code used to look like this : .all.paginate :per_page => events_per_page, :page => params[:page] delete the "all" before paginate. Hope it works for you. :)

Try putting this in your Gemfile instead:

gem "will_paginate", "~> 3.0.pre2"

Try using

def index
    @posts = Post.all.paginate(:page => params[:page], :per_page => 2 )

    respond_to do |format|
    format.html # index.html.erb
    format.xml  { render :xml => @posts }
  end
end
