Another nooby question - I have these two models in my project:
class Invoice < ActiveRecord::Base
has_many :items
end
and
class Item < ActiveRecord::Base
belongs_to :invoice ,:foreign_key=>'invoice_number',:primary_key=>'invoice_number'
end
So in my controller, I want to add new item to the invoice by pressing a button which is binded to an action. The action will generate a form to let the client fill in the information about the item. I want to something like this in controller:
#invoice.items << Item.new
This operation might be wrong ,but the problem is , Rails tells me that there is undefine method 'items'. Does anybody could give me a hint on how to fix this?

Feedback for the Question:
Thank you for you guys helping me on this mass.I have solve the problem - I found a misspelling (missing 's'), and I have sorry for taking your time.
Thanks again
Did you create these models in your database and give Item an invoice_number?
rails g migration AddInvoiceNumberToItems invoice_number:integer
rake db:migrate

You're assigning the id to the parent setter, while you should use parent_id here.
Try changing:
#micropost.parent = params[ :parent_id]
to:
#micropost.parent_id = params[:parent_id]

That quick IRB experiement leads me to the conclusion that your variable json_infos is nil.
Are you sure you don't want docker_path = '/usr/bin/' (with the trailing slash)? Unless you have the directory /usr/bindocker ...

I'm new to Rails. I'm working with Devise and I'm getting this error when I try to sign in
uninitialized constant ActiveSupport::SecureRandom
I'm running Rails 3.2.8 and Devise 2.1.2
Let me know if you need to see anything else.

Try using SecureRandom instead of ActiveSupport::SecureRandom. ActiveSupport::SecureRandom was deprecated in Rails 3.1 and removed in Rails 3.2
May be you are using
Devise.friendly_token
Instead of this use:
SecureRandom.base64(15).tr('+/=', 'xyz')
It may work.

#Ryan Bigg - here's the stack trace. I'm not sure what happened, but I'm pretty sure its Will_paginate.
#mohamed.magdy - As far as I understand, Will_paginate broke when 3.1 was released but then was fixed later. I have got the new will_paginate version to work in 3.1, but it doesn't work in this show action for some reason.
