Hi,
I am trying to figure out why I am receiving the following error.  I am
following an Apple Developers Rail Application tutorial.

>> event.expenses.create(:vendor => vendor1, :amount =>75.00)
NameError: undefined local variable or method `vendor1' for
#<Object:0x389a0>
  from (irb):2


Here is what I have for the models


class Event < ActiveRecord::Base
  validates_presence_of :name
  validates_numericality_of :budget, :greater_than => 0.0

  has_many :expenses
  has_many :vendors, :through => :expenses
end


___________________

class Expense < ActiveRecord::Base
  belongs_to :event
  belongs_to :vendor
end

___________________

class Vendor < ActiveRecord::Base
  has_many :expenses
  has_many :events, :through => :expenses
end


I read another post where they had issues with Xcode not saving and
having to restart terminal.  I have done both and everything looks
right.
Thanks in advance for any help!

Link? The reason is you're using a temporary variable you haven't set
to any value before you're using it. You probably want a string
'vendor1' rather than vendor1 which is a temp variable.
