Example text

If you’re willing to agree to the defaults, you generally have less code to write. The reason Rails does this comes back to the idea of less software. Less software means making fewer low-level decisions, which will make your life as a web developer a whole lot easier. And easier is a good thing. Don’t Repeat Yourself Rails is big on the DRY principle. DRY stands for don’t repeat yourself, a principle that states information in a system should be expressed in only one place. For example, consider database configuration parameters.

By separating concerns into different layers, changes to one of them don’t have an impact on the others, resulting in faster development cycles and easier maintenance. The MVC Cycle Although MVC comes in different flavors, control flow generally works as follows (see Figure 1-1): 1. The user interacts with the interface and triggers an event (for example, submits a registration form). 2. The controller receives the input from the interface (for example, the submitted form data). 3. The controller accesses the model, often updating it in some way (for example, by creating a new user with the form data).

It will even give you some information about your Ruby environment. Rails ships with a built-in, zero-configuration, pure Ruby web server that makes running your application in development mode incredibly easy. You start up the built-in web server using the server command in the script directory. To start the server now, enter the following command. $ ruby script/server => Booting WEBrick... 0 on port 3000. Don’t be alarmed by this all-zeros address. It simply means that the server is running locally on your machine.
