Join Kevin Skoglund for an in-depth discussion in this video Binding, part of Ruby: Files, Formats, Templates.
- [Instructor] In this movie we're going to learn…about a very cool feature with IRB called binding.…Binding is based on the idea that every Ruby object…stores its instance variables in a Binding object.…It's actually a class in Ruby called Binding.…We don't need to know much about the class,…we just need to know that it's used for the storage…of instance variables.…And we can access that Binding object…with a private instance method called binding.…Every Ruby object has one.…Where this is really powerful is that it allows us…to pass in the binding as an argument to ERB result.…
So ERB then receives this binding object,…which has a collection of instance variables…stored inside of it, and that gives our template…access to those instance variables…so that it can make use of them in the template.…Now this only works with instance variables,…it doesn't work with local variables…and it doesn't work with class variables.…And that makes instance variables a little bit special…when we're working with templating.…Let me show you a quick demo.…
