Hi
Thanks for your reply. My model code is
class User ActiveRecord::Base
acts_as_authentic
belongs_to :company
end
class Company ActiveRecord::Base
has_many :users
accepts_nested_attributes_for :users
end
My companies controller is
def new
@company = Company.new

Sounds like you do not have your associations defined correctly in your
model.
In your Buyer model you should have this line:
belongs_to :status
In your Status model you should have this line:
has_many :buyers
HTH,

That was it! Thank you
I am trying to get a file from the amazon bucket but it says string
contains null byte. any idea how to get the file to download like a
regular file? The file is there at the location.
f = Heypub.value @bucket
send_file( f , :type = FileExtns[ext]['mime'], :disposition =
'attachment')

I'm trying to wrap my head around what information is session specific
and what isn't.
If I do
User::x = 1
will User::x == 1 for all sessions on the same machine?
I think it is the same on the same, but I'd like confirmation.

Well as I understand when instance dies you could lose your static ip
and you can lose all your data on the instance?
So I also need to find another service to host the database.
But I understand that all those type of issues can be fixed by using
Rightscale or maybe
100 matches
