Question

I’m new in RoR, and I want to include pagination in my application.

Which is the best way to perform this task? Please suggest me. Is it possible to use will_paginate gem in rails 3.2.3 ?

If yes, in which method I should include:

Post.where(:published => true).paginate(:page => params[:page]).order('id DESC')  

Post.page(params[:page]).order('created_at DESC')    

Answer 1

Yes, it is possible to use will_paginate gem in rails 3.2.3 applications.

And the code will depends on what each action will perform.

The code below usually goes on a #index method, in your PostsController.

@posts = Post.where(:published => true).paginate(:page => params[:page]).order('id DESC')

So, in your posts/index.html.erb view file you can use the following code to display the pagination links:

<%= will_paginate @posts %>
