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 ?

如果是，我应该包括在哪种方法中:

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')    

推荐答案

是的，可以在 rails 3.2.3 应用程序中使用 will_paginate gem.

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

代码将取决于每个操作将执行的内容.

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

下面的代码通常使用 #index 方法，在您的 PostsController 中.

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

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

因此，在您的 posts/index.html.erb 视图文件中，您可以使用以下代码来显示分页链接:

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

<%= will_paginate @posts %>
