Ruby on Rails

Thanks Colin, here are the models and tables. Also to be sure went in to db console and verified the actual table names just in case something went awry. Also at bottom are the three rspec/shoulda errors. I have to be doing something wrong but if I am I don't see it.

class XpJurisdictionState < ActiveRecord::Base
  has_many :xp_jurisdiction_taxes
end

class XpJurisdictionTax < ActiveRecord::Base
  belongs_to :account_subcode
  belongs_to :xp_jurisdiction_states
end

  create_table "xp_jurisdiction_states", :force => true do |t|
    t.string   "state_code"
    t.string   "state"
    t.string   "billing_item"
    t.string   "billing_memo"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  create_table "xp_jurisdiction_taxes", :force => true do |t|
    t.integer  "xp_jurisdiction_state_id"
    t.integer  "account_subcode_id"
    t.decimal  "tax"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

public | xp_jurisdiction_states               | table    | postgres
 public | xp_jurisdiction_states_id_seq        | sequence | postgres
 public | xp_jurisdiction_taxes                | table    | postgres
 public | xp_jurisdiction_taxes_id_seq         | sequence | postgres


  1) AccountSubcode
     Failure/Error: it { should have_many(:xp_jurisdiction_taxes) }
     NameError:
       uninitialized constant AccountSubcode::XpJurisdictionTaxis
     # ./spec/models/account_subcode_spec.rb:16:in `block (2 levels) in <top (required)>'

  2) XpJurisdictionState
     Failure/Error: it { should have_many(:xp_jurisdiction_taxes) }
     NameError:
       uninitialized constant XpJurisdictionState::XpJurisdictionTaxis
     # ./spec/models/xp_jurisdiction_state_spec.rb:4:in `block (2 levels) in <top (required)>'

  3) XpJurisdictionTax
     Failure/Error: it { should belong_to(:xp_jurisdiction_states) }
       Expected XpJurisdictionTax to have a belongs_to association called xp_jurisdiction_states (XpJurisdictionTax does not have a xp_jurisdiction_states_id foreign key.)
