Subject: assigning hash to attributes

Hi,

as i mentioned before, i'm pretty new to ruby. So i'm trying to optimize 
my code and learn the advantages of this nice language :).

What i'm trying this time is to pass a hash of parameters (passed by a 
HTML form i.e.) to an new Object and then automatically assign the 
values of this hash to the attributes of that object named like the keys 
of that hash.

After a lot of research and even more trail & error i ended up with this:

class Example

   def initialize ( params = {} )
       assign_params params unless params.nil?
   end

   def assign_params params
     params.each { | key, value | eval "@#{key} = '#{value}'" }
   end

end

At least, it works ;)
Are there any suggestions for smarter or more efficient ways to 
accomplish this? Escpecially the usage of eval() to assign variable 
variables seems pretty workedaround to me.

Thy for any hint :)
D.
