How to print the instance variables of a class with name and value?

I've got an ActiveModel class SupportCase which has certain instance variables (created with attr_accessor).

For a given object of that class, how I can print out the names of its instance variables as well as the values.

I've tried:

support_case.instance_variables.each { |a,b| puts "#{a} #{b}" }

support_case.instance_variables.each { |a| puts "#{a} #{support_case.send(a)}" }

The latter didn't work since it creates the call support_case.@var whereas it should be support_case.var. So I could strip the @ but there has to be some cleaner way of doinf what I want to do, right?

Thanks!

Thanks to Divya Sharma, I've found the method I was looking for:

#instance_variable_get

I used in the following way (regarding my question):

support_case.instance_variables.each { |ivar| puts "#{ivar}: #{support_case.instance_variable_get(ivar)}" }
