    <p>I'll start off with a bit of context to my question. I have a group of offices which each have reviewers associated with them. A reviewer can only be associated with one office. I want to create two select boxes. One lists all of the reviewers that are associated with the office I am viewing, the other lists all of the reviewers that are available (which is basically all of the reviewers that aren't already assigned to this office).</p> <p>The goal of the current reviewer's listbox is to set their office to nil when they are selected. The goal of the available reviewers listbox is to set their office to this office's id when they are selected. I'm not sure how to change only the reviewers' office_id when using a select box. </p> <p>Code-wise, what I have so far is this:</p> <p><strong>office_controller.rb</strong></p> <pre><code>def edit @office = Group.find params[:id] if params[:id] @current_reviewers = Reviewer.find_all_by_group_id(@office.id) @available_reviewers = Reviewer.where('group_id &lt;&gt; ?',[@office.id]) end def update ? end </code></pre> <p><strong>office/edit.html.erb</strong></p> <pre><code>&lt;% form_for(@office, :url =&gt; {:controller =&gt; :office, :action =&gt; :update, :id =&gt; @office.id}, :html =&gt; {}) do |f| %&gt; ... &lt;%= select_tag 'removedReviewers', options_from_collection_for_select(@current_reviewers, "id", "display_name"), :multiple =&gt; true %&gt; &lt;%= select_tag 'chosenReviewers', options_from_collection_for_select(@available_reviewers, "id", "display_name"), :multiple =&gt; true %&gt; ... &lt;% end %&gt; </code></pre> <p>Any suggestions would be greatly appreciated. Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
