destination - Path to put pages in. Expects / in the end. Produced pages will have following path #{destination}pages/index.html, #{destination}pages/2.html

template - Path to the template. If you don't want to render template by itself pass ignore: true to extra arguments.

objects - Objects to paginate. You will have access to them inside the template as objects.

locals - If you have need any other variables inside the template, pass them allong as you normally would.

ignore - See template option description.

paginate(
  destination: '/',
  template: 'template.html',
  objects: objects,
  locals: { },
  ignore: true
)

Access from template

Inside template, iterate over per_page number of objects

  - paginator[:objects].each do |object|
    // render object 

  = previous_page_link
  = next_page_link

Helpers

Paginator provides a few helper methods:

• last_page_link
• previous_page_link
• next_page_link
• last_page_link
• pages They work like link_to helper and support same the arguments.

Here is a haml example with bootstrap styles:

- if pages.count > 1
  %ul.pagination
    - prev_link = previous_page_link text: '<', class: 'page-link'
    - next_link = next_page_link text: '>', class: 'page-link'

    %li.page-item{ class: ('disabled' if prev_link.blank?) }
      - if prev_link
        = prev_link
      - else
        .page-link <

    - pages do |page, destination|
      %li.page-item{ class: ('active' if page == paginator[:page]) }
        = link_to page, destination, class: 'page-link'

    %li.page-item{ class: ('disabled' if next_link.blank?) }
      - if next_link
        = next_link
      - else
        .page-link >
