string as attribute

as the first solution is impossible to do for various reasons

well there's always read_attribute (and remember that
foo.read_attribute(:bar) is the same as foo[:bar] )

I think rather than doing read_attribute, you should do

def get_value_for_column(attribute)
send(attribute)
end

because if you have

def something
    read_attribute(:first) + read_attribute(:second)
end

then get_value_for_column("something") would not work in case of read_attribute in get_value_for_column

Sort of depends what problem you are trying to use (eg send won't work
if you had a legacy schema with a column name that isn't a legal name
for a ruby method).

yeah you are right. Thanks for clarifying
