Having trouble with update_attributes() after member access

Rails
1

I’m having problems in a controller i am writing. i get this exception:
wrong number of arguments (1 for 0)

this does not work:

@voicemail_user = VoicemailUser.find(session[:asterisk][:user_id])

if (@voicemail_user.password == params[:pwd][:current])
  @voicemail_user.update_attributes({"password" =>

params[:pwd][:newpwd2]})
end

but this works:

@voicemail_user = VoicemailUser.find(session[:asterisk][:user_id])
@voicemail_user.update_attributes({"password" =>

params[:pwd][:newpwd2]})

What am i doing wrong?

OK, looks like i can’t edit my OP here (heh heh new to this forum).
I have a column called callback in my table. callback is a method that
is used by ActiveRecord and things go crazy when it is an attribute
also.

I tried adding these methods as a work around to alias the callback
column:

def callback_column=(value);
attributes[“callback”] = value;
end

def callback_column
attributes[“callback”]
end

but it doesn’t fix things like [“callback_column”] etc or when i do a
VoicemailUser.content_columns to iterate over the hash.

is there a general purpose fix to alias column names when they conflict
with rails?
