Может кто-нибудь сказать мне, что я сделал не так?
Я побежал script/generate model CityZipMSA city:string state:string zip:integer MSA:integer
А потом побежал rake db:migrate, и я получил следующую ошибку
(в / Users / MMyself / app_dev / property) грабли прерваны!Произошла ошибка, эта и все последующие миграции отменены:
неинициализированная константа CreateCityZipMsas
Мой файл миграции:
class CreateCityZipMSAs < ActiveRecord::Migration
def self.up
create_table :city_zip_msas do |t|
t.string :city
t.string :state
t.integer :zip
t.integer :MSA
t.timestamps
end
end
def self.down
drop_table :city_zip_msas
end
end
При запуске rake db:migrate --trace
Я получаю
