Passing the selected value from select_tag to params without having a form_tag

I have this code:

<div class="export-buttons">
    <div class="row">
        <div class="col-lg-offset-4">
            <%= label_tag :year, "Any" %>
            <%= select_tag :year,options_for_select((2014..2040).map{|x| x.to_s}),name:"params[year]" %>

        </div>
    </div>
    <div class="row">
        <div class="col-lg-4 col-lg-offset-4">
            <%= link_to "Revenue summary", revenue_summary_path(format:"pdf"),class:"btn btn-bg btn-default", role:"button"  %>
        </div>
    </div>
    <div class="row">
        <div class="col-lg-4 col-lg-offset-4">
            <%= link_to "Fees summary", fees_summary_path(format:"pdf"),class:"btn btn-bg btn-default", role:"button"  %>
        </div>
    </div>
</div>

And I would like to pass the selected value in the select_tag to params. However I do not have a form_tag, hence there's no Submit button either.

Is there a way to "embed" it inside the params hash? Or do I need a form_tag for sure? In case of the latter, what would be the best approach, two submit-buttons + one path + if/else @controller?

If you really want to avoid form tags, which may seems logical too since you want to have multiple download links which would simply send out an additional parameter of select_tag to the backend. You can use javascript for same.

  • Instead of link_to , you can use a binding to a javascript function onclick of these links.
  • The binded function would execute the url and before that it would append the current value of select filter via javascript to the url.
