Question

I’m very new to Ruby on Rails and learning while trying to fix some bugs on my company website. I’m trying to paginate a collection of records combined with a particular anchor, i.e. when user clicks on the next/previous page, the pagination happens and user lands on a particular section of the page. This is how my code looks at the moment:

view

<%= page_navigation_links @student_logs, :page %></p>

controller:

@student_logs.paginate(:page => params[:page], :per_page => 10)

application_helper

def page_navigation_links(pages, param_name=:page)

  will_paginate(pages, :class => 'pagination', :inner_window => 2, :outer_window => 0, :renderer => BootstrapHelper::LinkRenderer, :previous_label => '←'.html_safe, :next_label => '→'.html_safe, :param_name => param_name)

end

This works fine for my pagination, but I need to fit a reference to an ‘anchor id’ into this code, like Student Logs, so that when user navigates to a different page the browser navigates the user to the heading with id: “student_logs”.

I can’t figure out how to do this. Can anyone help?

Answer 1

I do not have direct experience with it. However, this link shows a way. I could not test but you can certainly do.

<%= will_paginate @posts, :params => {:anchor => i} %>

If this works, then you can utilize this way in your helper:

def page_navigation_links(pages, param_name=:page)
  will_paginate(pages, :params => {:anchor => "#ANCHOR"}, :class => 'pagination', :inner_window => 2, :outer_window => 0, :renderer => BootstrapHelper::LinkRenderer, :previous_label => '←'.html_safe, :next_label => '→'.html_safe, :param_name => param_name)
end

You can replace #ANCHOR as you need.
