I want to implement Ajax on my ruby on rails project. I currently use the will_paginate gem. Whenever I click for the next page, the whole page reloads, which I don't want to happen. How can I prevent this? I found a similar question but it didn't work for me. I guess it's because I am using Rails 5.2.2? I am not sure.
My index.html.erb looks like this:
<div class="row justify-content-center align-items-center">
<div class="page_info">
<h5><%= page_entries_info @imports %></h5>
</div>
</div>
<div class="row justify-content-center align-items-center">
<div class="page_info">
<h5><%= will_paginate @imports, :container => false %></h5>
</div>
</div>
Here is my code in my controller.rb:
class ImportsController < ApplicationController
def index
@imports = Import.all
@imports = Import.paginate(:page => params[:page], :per_page => 5)
end
To paginate with AJAX instead of a page refresh, you'll need to add a data-remote="true"
to all of the paginate links.
data-remote="true"
is a rails helper that will cause the server to interpret the request as JS instead of HTML.
First step, create a new helper:
module RemoteLinkPaginationHelper
class LinkRenderer < WillPaginate::ActionView::LinkRenderer
def link(text, target, attributes = {})
attributes['data-remote'] = true
super
end
end
end
Second, add a paginate
method to the application_helper.
module ApplicationHelper
def paginate(collection, params= {})
will_paginate collection, params.merge(:renderer => RemoteLinkPaginationHelper::LinkRenderer)
end
end
Then, you can replace this:
<div class="row justify-content-center align-items-center">
<div class="page_info">
<h5><%= will_paginate @imports, :container => false %></h5>
</div>
</div>
with this:
<div class="row justify-content-center align-items-center">
<div class="page_info">
<h5><%= paginate @imports, :container => false %></h5>
</div>
</div>
