undefined method `paginate' for

Question

I am using Ruby on Rails 3.2.1 and Kaminari gem 0.13.0.

I have added gem 'kaminari' in my gemfile, then ran Bundle install.

In controller I have @posts = Post.order("name").page(params[:page])

In view:

<%= paginate @posts%>
        <% @posts.each{|posts| %>
            <h1 class="title"><%= link_to posts.title, posts %></h1>
                <p class="byline">Raksts izveidots: <%= posts.created_at.utc.strftime("%d.%m.%Y") %></p>
                <div class="entry">
                    <p><%= posts.content %></p>
                </div>
            <p class="meta"><a href="#" class="more">Read More</a> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <a href="#" class="comments">Comments</a> (33)</p>           
        <% } %>
        <%= paginate @posts%>

But in result I have undefined method 'paginate' for #<#<Class:0x3cf68b8>:0x2ab92b0>.

Anyone could help me?

 class PostsController < ApplicationController
    # GET /posts
    # GET /posts.json
    def index
      @posts = Post.order(:name).page(params[:page]).per(2)
      @posts = Post.order('posts.id DESC')


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

Just done it, but now I got another error. `undefined method 'current_page' for` — RydelHouse, Apr 07 '12 at 12:46
`undefined method 'current_page' for#` Extracted source (around line #5): `<%= paginate @posts%>` — RydelHouse, Apr 07 '12 at 12:54
You redefine paginated collection by `@posts = Post.order('posts.id DESC')`. Remove this line. — mikdiet, Apr 07 '12 at 13:29

def index
  @posts = Post.order(:name).page(params[:page]).per(2)

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

But how I can now order posts by created date? – RydelHouse Apr 07 '12 at 14:13
just pass multiple parameters to the order method like Post.order(:name,'id DESC').page(params[:page]).per(2) – alex Apr 07 '12 at 14:23

I think you can do:

@posts = Post.order(:name).page(params[:page]).per(2), order: 'post_id desc',
                                                         per_page: 10

Hope this helps.
