    <p>I have a model <strong>students</strong>. in <em>studentsController</em> I select a collection of students. I want to attach a flag to the first and the last record. </p> <p>I'll display the list of students with a partial like this: <strong>students/_student</strong> and when a user clicks each student, they'll get a popup. </p> <p>I want to use the flag to determine whether this student is the first/last so that I can add a query parameter to the url. So for instance, the url will look like this when you hover over the first student: <strong>localhost:3000/student/1?location=first</strong></p> <p>When displaying though a partial, the collection is not present in the partial, and so I cannot just do a test like this: student.first?</p> <p>Any ideas? Thank you.</p> <p>[EDIT]. This was originally a reply to @neils, but I figured I'd put it out there: It works however I have another issue. Because I'm using an "auto-scroll" feature, which loads in more students as the user scrolls down the page ( 3 at a time), the "first" and "last" gets added to the first and third student of each row rather than the actual first and last of the collection. The way I do the auto-scroll: I use $.getScript to request the <strong>index.js.erb</strong> file. That file renders the <strong>students/_student</strong> like so: <em>render @students</em>, and attach to a container div. I render the url in that template (<strong>students/_student</strong>), so the params gets rendered every first/third time.</p>

    3. CO@Sush I'm not sure I understand what you mean. I will use params[:location] to get it back and figure out whether it's the first or last item. My problem is attaching the location params to the url in the first place. I need to figure when to attach it, and so I need to know which item is the first and which one is the last.

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.
