If you need extra functions in your view, you normally declare those inside a helper. For each controller, if there is a helper it is automatically loaded. For instance, if you have a PeopleController, in the app/helpers folder, there should be a people_helper.rb, and it should look like this module PeopleHelper def name #do something … Read more
Try this: def foo_list items content_tag :ul do items.collect {|item| concat(content_tag(:li, item))} end end

Braces define an anonymous function, called a block. Tokens between the pipe are the arguments of this block. The number of arguments required depends on how the block is used. Each time the block is evaluated, the method requiring the block will pass a value based on the object calling it. It’s the same as … Read more
I offer up my own explanation from this answer, slightly modified: “Blocks” in Ruby are not the same as the general programming terms “code block” or “block of code”. Pretend for a moment that the following (invalid) Ruby code actually worked: def add10( n ) puts “#{n} + 10 = #{n+10}” end def do_something_with_digits( method … Read more
