Set Attribute Dynamically of Ruby Object

Question

How can I set an object attribute dynamically in Ruby e.g.

def set_property(obj, prop_name, prop_value)
    #need to do something like > obj.prop_name =          


        

Answer 1

Use send:

def set_property(obj, prop_name, prop_value)
    obj.send("#{prop_name}=",prop_value)
end
