ransack proper filter of searches in association models

I have 2 models Universityand Course. There is a has_many through relationship between both.

I am using Ranstack for search queries on the University model as following:

<%= search_form_for @search do |f| %>
  <div class="field">
    <%= f.label :title_cont, "University name" %>
    <%= f.text_field :title_cont %>
  </div>
  <div class="field">
    <%= f.label :courses_course_type_in, "Course type" %>
    <%= f.select :courses_course_type_in,  Course.course_type.options, {} %>
  </div>
<% end %>

and in my controller i have:

@search = University.search(params[:q])
@universities = @search.result

The :courses_course_type_in is well understood in the query in the sense that i get only the universities that offer that specific type of courses(let's say graduate courses).

But in the other hand, when i come to display the courses, @universities.courses contains all courses of all the types available(graduate , undergrade, certificate, continuing education...).

Is there an easy way ( in ransack preferably ) to get only the wanted courses in @universities.courses ? (graduate in this case)

Thanks!

Did you try with :

<%= f.select :courses_course_type_eq,  Course.all.collect{|c| [c.course_type, c.course_type]} %>
