Ruby On Rails Lesson
Rails-Flavored Ruby
Grounded in examples from Chapter 3, this chapter explores some elements of Ruby important for Rails. Ruby is a big language, but fortunately the subset needed to be productive as a Rails developer is relatively small. Moreover, this subset is different from the usual approaches to learning Ruby, which is why, if your goal is making dynamic web applications, I recommend learning Rails first, picking up bits of Ruby along the way. To become a Rails expert, you need to understand Ruby more deeply, and this book gives you a good foundation for developing that expertise. As noted in Section 1.1.1, after finishing the Rails Tutorial I suggest reading a pure Ruby book such
as Beginning Ruby, The Well-Grounded Rubyist, or The Ruby Way.
This chapter covers a lot of material, and it’s OK not to get it all on the first pass. I’ll refer back to it frequently in future chapters.
Motivation
As we saw in the last chapter, it’s possible to develop the skeleton of a Rails application, and even start testing it, with essentially no knowledge of the underlying Ruby language. We did this by relying on the test code provided by the tutorial and addressing each error message until the test suite was passing. This situation can’t last forever, though, and we’ll open this chapter with an addition to the site that bring us face-to-face with our Ruby limitations
When we last saw our new application, we had just updated our mostly static pages to use Rails layouts to eliminate duplication in our views (Listing 4.1). Let’s focus on one particular line in Listing 4.1:
This uses the built-in Rails function stylesheet_link_tag (which you can read more about at the Rails API) to include application.css for all media types (including computer screens and printers). To an experienced Rails developer, this line looks simple, but there are at least four potentially confusing Ruby ideas: built-in Rails methods, method invocation with missing parentheses, symbols, and hashes. We’ll cover all of these ideas in this chapter.
