Join Kevin Skoglund for an in-depth discussion in this video Text helpers, part of Ruby on Rails 3 Essential Training.
Rails offers many helpers to assist us in performing common text manipulations.…In this movie, we'll look at a few of the most useful.…Since we don't have a reason to use all of these helpers in our application yet,…we're going to create a sort of sandbox page where we can demonstrate them all.…So I'm thinking that we'll create this sandbox page on the demo_controller.…So I'm just going to create a new action here and call it text_helpers.…It's not going to do anything in the action, but we are going to need a…new template for it.…So inside the demo folder of the views, I'm going to put in…text_helpers.html.erb.…
So this gives us a place where I can just paste in a lot of code that we can then look at.…You can pause the movie and copy it down, or just follow along with me.…First, I've got just a simple variable assignment.…text = a double quoted text string.…If I have these double quoted is significant, because I'm using some escape…characters in it and it's important.…To respect those escape characters, we need double quotes around it.…
