    <p>If I have a situation where paramters aren't passed explicitly via the URL because there are some ajax elements on the one page, how do I access an ID for an object loaded much earlier....for instance. </p> <ol> <li>User selects client.id=1</li> <li>User selects, project.id=3</li> <li>User selects, stages.id=9</li> </ol> <p>But none of those IDs are passed through the URL. </p> <p>In that example, by the time the user reaches step 3, I would like to access the <code>client.id</code> in the Client controller....how do I do that ?</p> <p>If it were in the URL, I would just do <code>client = Client.find(params[:id])</code>, but if I do that now, by step 3, what gets returned as the ID parameter is the Stage ID - which is not what I want.</p> <p>This is what their actions in their respective controllers look like:</p> <pre><code>Client Step Action def step client = Client.find(params[:id]) projects = client.projects respond_to do |format| #format.html { redirect_to("/") } format.html { render :partial =&gt; "projects/show", :collection =&gt; projects, :as =&gt; :project, :layout =&gt; false, :status =&gt; :ok } end end Project Step Action def step project = Project.find(params[:id]) stages = project.stages respond_to do |format| format.html { render :partial =&gt; "stages/show", :collection =&gt; stages, :as =&gt; :stage, :layout =&gt; false, :status =&gt; :ok } end end Stage Step Action def step stage = Stage.find(params[:id]) uploads = stage.uploads respond_to do |format| format.html { render :partial =&gt; "uploads/show", :collection =&gt; uploads, :as =&gt; :upload, :layout =&gt; false, :status =&gt; :ok } end end </code></pre>

    2. COThat doesn't quite help me. I already have the form setup and all that good stuff. I just need to be able to get access to the ID in Step 1 and other steps.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
