Suppose you have a Model called Article that contains a text field and a format field.
You would like to use haml, textile or HTML to edit your Article from the admin interface.
create_table "articles", :force => true do |t| t.string "title" t.text "body" t.string "formatting_type", :limit => 20, :default => "HTML" end
app/models/article.rb
It’s quite simple. All you have to do is to add this helper in your application_helper.rb
def print_formated(type,text) case type when "HTML" text when "Plain Text" h text when "HAML" Haml::Engine.new(text).render when "Syntaxy" Syntaxi.line_number_method = 'none' Syntaxi.new(text).process when "Textile" RedCloth.new(text).to_html end end
In your views/articles/_form.haml add the select field.
= label :article, :formatting_type = select(:article, :formatting_type, Article::FORMATTING_TYPES.collect {|p| p }, { :include_blank => false })
Then in the Show view (articles/show.haml)
.article .title %h1 = h @article.title .body = print_formated(@article.formatting_type, @article.body)
that’s pretty much it.
