Question

I have an array @level1 which looks like this :

[[3.0, 4, 2], [2.0, 48, 3], [2.1, 56, 4], ............]

I want to apply pagination on this array such each page displays only a few rows at once. I tried this:

@temp1 = @level1.paginate(:page => params[:page])

But it throws the following error:

undefined method `paginate' for [[3.0, 4, 2], [2.0, 48, 3], [2.1, 56, 4]]:Array

How can I perform pagination on this using will_paginate?

Answer 1

Sure, you can use WillPaginate::Collection to construct arbitrary pagination across collections. Assuming an array called values:

@values = WillPaginate::Collection.create(current_page, per_page, values.length) do |pager|
  pager.replace values
end

You can then treat @values just like any other WillPaginate collection, including passing it to the will_paginate view helper.
