Call method from view

I want to call a method that i have implemented in the controller and
i don't know how to call it from the index.html.erb file.
Please help.

If you have utility methods you wish to call from views use the Rails
helper convention and put them in modules under app/helpers - you can
use the rails command line script to help you generate them if need


Can you explain what sort of function this is? What is it doing? The
answer to the best way to solve the problem depends on what the method


Because i am new to Rails, in need to understand better how rails
work.First i have created a controller and views of the controller in
netbeans.In controller i have the following code:

class SayController < ApplicationController

def hello // 'hello' is name of the view, inside 'hello' method i can
create other methods and call them ONLY from the hello.html.erb or
   @items=["item1","item2" ...] // i want to create an array and show
all the elements in hello.html.erb.


Please specify if the code is correct.Also in hello.html how i can
call the array or the method and show the content.

I suggest you work through some tutorials on Rails.
is good and free to use online. Make sure that the tutorial uses the
version of rails that you have installed. Also look through the Rails

Once you have worked right through a good tutorial then you will be
able answer most of your questions yourself.
