Class: TagList

Inherits:
Array
  • Object
show all
Defined in:
lib/tag_list.rb

Overview

Simple extension of Array. The reason we need this class is so that we can make form views play nicely with our tags.

For example, we can now write things like this in our form views:

form_for(@taggable_model) do |f|
  <div class="field">
    <%= f.label :tag_list %>
    <%= f.text_field :tag_list %>
  </div>
end

This will create a text field as we would expect, and will properly update our model’s tags when our model is being changed.
