迁移错误

Question

我尝试运行数据库迁移，但出现以下错误

PG::UndefinedTable: ERROR:  relation "authie_sessions" does not exist

     

：ALTER TABLE＆＃34; authie_sessions＆＃34; ADD＆＃34; two_factored_at＆＃34; timestamp / home / levi / .rvm / gems / ruby​​-2.4.1 / gems / activerecord-5.1.5 / lib / active_record / connection_adapters / postgresql / database_statements.rb：73：in`async_exec＆＃39;

我的迁移文件是

class AddTwoFactorAuthFieldsToAuthie < ActiveRecord::Migration[4.2]
  def change
    add_column :authie_sessions, :two_factored_at, :datetime
    add_column :authie_sessions, :two_factored_ip, :string
    add_column :authie_sessions, :requests, :integer, :default => 0
    add_column :authie_sessions, :password_seen_at, :datetime
  end
end

我的database.yml是

default: &default
  adapter: postgresql
  encoding: utf8
  pool: 5
  username: postgres
  password: postgres
  database: staytus
  host: 127.0.0.1

production:
  <<: *default

development:
  <<: *default

test:
  <<: *default
  database: staytus_test

我正在使用postgresql

Answer 1

检查authie_sessions和staytus两个数据库中是否存在staytus_test表。
