What version of Rails? I see a Railscast here from 2010 that has that very same
code, and no error. But it also has an initialize method hand-written into the
model:
def initialize(attributes = {})
attributes.each do |name, value|
send("#{name}=", value)
end
end
You might need something like that to "persist" the data long enough for your
controller to do something with it.
