I've starting programming on ASP.NET MVC Framework a year ago. Recently. I've learning Ruby On Rails Framework There is "custom html helper" feature in ASP.NET MVC So I can create my own html helper 

<%= Html.MyOwnHtmlHelper() %>

I've learned that there is html helpers in Ruby such as

<% text_area %>

which render at html

I have a question. Can I create my own html helper for rendering my own html?

To create a new helper:

  1. choose a name for the helper file, for instance tags_helper.rb
  2. create the file in the /app/helpers directory

  3. create a module according to the file name. In this case

    module TagsHelper
end

  4. define your helper as method

    module TagsHelper
  def hello_world(name)
    "hello #{name}"
  end
end

Now you can use the hello_world helper method in your view.
