However, for more complex queries, you may need to craft a SQL statement manually. Specifically, you can use find_by_sql to search for any arbitrary SQL query, and this allows you to ask for virtually any type of information. For example, if a vehicle_model column existed in your Accident model, you could group by vehicle_model and run two aggregate functions: average age and average accident_count. This would give you an average owner age and an average number of accidents per vehicle, so you could get some idea whether, say, a Ford Explorer was a safer ride than a Honda CRX. (Of course, driver control would play a significant part, and hence the average age is a helpful statistic.) You can t use multiple aggregate functions with calculate, but you can with find_by_sql, like this:

<script type="text/javascript"> document.observe("dom:loaded", function() { $('container').select('li').each( function(li) { new Draggable(li); }); Droppables.add('drop_zone'); }); </script>

Now, we have all the necessary tools needed to populate Alanna s new blog with all of the content that she gave us. After a few short hours of entering her content into the system and formatting it as text using Textile, her page is up and running with the default theme (see Figure 9-14).

sql = "SELECT vehicle_model, AVG(age) as average_age, AVG(accident_count) AS average_accident_count FROM persons GROUP BY vehicle_model " Person.find_by_sql(sql).each do |row| puts "#{row.vehicle_model}, " << "avg. age: #{row.average_age}, " << "avg. accidents: #{row.average_accident_count}" end

Here, we re declaring our new ul as a droppable, but we re not providing an options argument. By default, this droppable will accept any draggable that is dropped onto it. Reload the page and drag an item from the left box to the right box. Nothing happens. You can drag the list items wherever you like, but you could do that already. Don t worry, this is by design. script.aculo.us does not make any assumptions about the purpose of the drag/drop operation, so it will only do what you tell it to do.

The output would look something like this:

There are two callbacks for droppables: onHover and onDrop. When a draggable is dragged over a compatible droppable (i.e., a droppable that would accept it), the onHover callback fires. When it is dropped onto a droppable, the onDrop callback fires. To illustrate this in the simplest way possible, let s add an onDrop callback to the preceding code:

So we ve got Alanna s site up and running from a content perspective, but let s do the customization to truly make it her site now and give it a visual flair that fits with what she needs. Fortunately, Typo comes with a great theme system that makes customizing surprisingly easy.

Droppables.add('drop_zone', { onDrop: function() { console.log("dropped!"); } });

Ford Explorer, avg. age: 43.010, avg. accidents: 0.400 Honda CRX, avg. age: 18.720, avg. accidents: 1.250 . . .

Now reload the page and try again. Make sure the Console tab of Firebug is visible so that you can see when messages are logged. You should see something like Figure 11-3.

The examples in 1 involved Transmegtech Studios, a hypothetical game development company. Now let s suppose Transmegtech Studios has merged with another small studio, J. Lee Games, and they want to analyze their combined base of game testers. Specifically, they want to answer two questions: How many players are at each salary rate Answering this question should give the merged companies a way to get a handle on their total beta-testing expenditures. This question can be answered with simple grouping in Active Record, so that will be tackled first. Which drink leads to the highest performance The Transmegtech people are having a dispute with the new personnel from J. Lee Games. The new testers and programmers drink Fresca, whereas the Transmegtech team prefers the Moxie energy drink. Both sides claim their drink is superior, and leads to higher productivity and mental agility. The management would like to know which drink leads to the highest performance, with the data broken down by wins per game. In the interests of fairness, they ve agreed to analyze data only from new titles developed by the joint company, so old data won t cloud the analysis. This question can be answered with a combination of grouping and aggregate functions, and that will be tackled second. For the examples in this chapter, you ll use the schema shown in Listing 2-1.
