Question

Lets say we have some basic AR model.

class User < ActiveRecord::Base
  attr_accessible :firstname, :lastname, :email
end

...

some_helper_method(attrib)
  ...
def  

Now I would like to pass someuser.firstname to helper and I would like to get both the value and the attribute name, for example:

some_helper_method(someuser.firstname)
> "firstname: Joe" 

some_helper_method(someuser.lastname)
> "lastname: Doe" 

Answer 1

I am not sure what you are trying to do but here is a possible solution:

def some_helper_method(object, attr)
  "#{attr}: #{object.send(attr)}"
end

Now you can call the helper as follows:

some_helper_method(someuser, :firstname)
# => "firstname: Joe"
