rails - display partial in another controllers view

I'm not sure why i can't get my index action to pass to my view. Basically i have a controller called "jobs" with a partial called "recent jobs" and i want to display that "recent jobs" partial in another contollers view called "static_pages".

I thought that all i would have to do is call the below in my static_pages/home.html.erb:

    <%= render partial: "jobs/recent_jobs" %>

but here's the error i get. apparently @jobs is nil.

ActionView::Template::Error (undefined method `each' for nil:NilClass):
2: <div class="homepage_recent_jobs">
3:   <div class="container">
4:       
5:     <% @jobs.each do |job| %>
6:       <% job.title %>
7:     <% end %>
8:

here's my partial in the jobs controller

    <div class="homepage_recent_jobs">
      <div class="container">

        <% @jobs.each do |job| %>
          <% job.title %>
        <% end %>
     </div>
   </div>

jobs index action

def index

  set_link_order_and_counters      

  @jobs = Job.all

  # calls scopes
  if params[:experience].present? 
    @jobs = @jobs.by_experience(params[:experience])
  end   

  if params[:num_days_past].present? 
    @jobs = @jobs.by_num_days_past(params[:num_days_past].to_i)
  end      


  @jobs = @jobs.paginate(page: params[:page], per_page: 5)
end

As you're working with @jobs, and rendering static_pages#home you need to define it first, you've defined it only in jobs#index, and that's why when the view is rendered the value is nil.

Adding @jobs in the proper controller should work:

class StaticPagesController < ApplicationController
  def home
    @jobs = Job.all
  end
end

And note with <%= render 'jobs/recent_jobs' %> Rails infers is a partial file, no need to use the partial option. Also to print the job's title you would need to use <%= %>.
