Question

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?

Answer 1

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.
