Problems with find(:all, :conditions)

I need find all people with "type" in 2,3,4,5...
so I wrote this find:

Person.find(:all, :conditions => ['type in (?)', "#{params[:types]}"]

and the params[:types] is an Array.

ActiveRecord generate this SQL:

select .... where type in ("12345")

But, I need this SQL instruction:

select .... where type in ("1", "2", "3", "4", "5" )

What is wrong?

thanks for your help.

Person.find(:all, :conditions => ['type in (?)', params[:types]])

If params[:types] is an Array, then don't force it to be a string by interpolating it yourself with "#{}".
