Hi,
I created the ArithmeticDisplayBean
class ArithmeticDisplayBean
attr_accessor :result
end
This is the controler
class RubyApplicationController < ApplicationController
@arithmeticDisplayBean
def arithmetic
if params[:paramaction] == ‘save’
arithmetic = Arithmetic.new
arithmeticDisplayBean = ArithmeticDisplayBean.new
arithmeticDisplayBean.result =
arithmetic.add(params[:num1].to_i,params[:num2].to_i)
end
end
end
How can I get the result from the arithmeticDisplayBean.result in the
view? Can anyone help?
you can use every instance variable you declare in the controller
instance in the view.
if you define result like this:
@result = arithmeticDisplayBean.result
the will display it if you write this:
<%= @result %>

This is an instance variable of the class, not the instance. It is
accessible through class methods, not instance methods. You should be
able
to remove this line.
def arithmetic
if params[:paramaction] == 'save'
arithmetic = Arithmetic.new
arithmeticDisplayBean = ArithmeticDisplayBean.new
This line
arithmeticDisplayBean = ArithmeticDisplayBean.new
loads your Bean into a local variable. Local variables are not
available in
your views. This should be
@arithmeticDisplayBean = ArithmeticDisplayBean.new
@arithmeticDisplayBean.result =
arithmetic.add(params[:num1].to_i,params[:num2].to_i)
end
end
end

If you use the instance variable then it will be available in your view.
Alternatively you can just stick the result into an instance array on
the
fly
@result = arithmeticDisplayBean.result =
arithmetic.add(params[:num1].to_i,params[
:num2].to_i)
