    copied!<p>I have a user class, which has_many resumes, each of which has many items. On my users/show page, I render multiple resumes, which is working. In my users_controller I have the following:</p> <pre><code>def show ... @resumes = @user.resumes.paginate(page: params[:page]) @resume = @user.resumes.build if user_signed_in? @resume_items = @user.res.paginate(page: params[:page]) @edu_items = @resume.edu.paginate(page: params[:page]) ... end </code></pre> <p>I defined the function res in my User model:</p> <pre><code>def res Resume.where("student_id = ?", id) end </code></pre> <p>And that worked quite well. However, I'm trying to do the same thing with the function edu in my Resume model:</p> <pre><code>def edu Education.where("resume_id = ?", id) end </code></pre> <p>but it's not working, @edu_items isn't being set to anything. Now I know it has to do with this method specifically, because if I change id to the id of a specific resume, that resume's items are rendered correctly, except across every resume. I know it's a simple fix, I've just been staring at it for way too long at this point and can't figure it out. Any advice would be amazing.</p> <p>EDIT: @makaroni4: Instead of having @educations = @user.educations, I'd rather keep the items from each resume separate. Is it possible to define a method like the educations one that will make @educations = @resume.educations?</p> <p>EDIT 2: I managed to get what I was trying to do to work, thanks for the advice. I solved it by doing away with the edu method altogether, and passing local variables to the partial:</p> <pre><code> &lt;%= render :partial =&gt; 'shared/edu', :as =&gt; :educations, :locals =&gt; {:resume_educations =&gt; resume_item.educations} %&gt; </code></pre> <p>shared/edu</p> <pre><code>&lt;% if resume_educations.any? %&gt; &lt;ol class="educations"&gt; &lt;%= render partial: 'shared/edu_item', collection: resume_educations %&gt; &lt;/ol&gt; &lt;%= will_paginate @educations %&gt; &lt;% end %&gt; </code></pre> <p>Probably not the cleanest solution, but it seems to work.</p>
