我在Rails应用程序中注册时遇到一些问题,出现错误
“列电子邮件不是唯一的”
尽管我知道我以前从未使用过这个特定的电子邮件地址。我以为我还是要检查数据库,然后运行:
rails console -e=test
查看
Users.all
以查看保存了哪些记录。但是,不仅没有一个被保存,而且我得到了错误:**SQLite3::SQLException: no such table: users: SELECT "users".* FROM "users"
ActiveRecord::StatementInvalid: SQLite3::SQLException: no such table: users: SELECT "users".* FROM "users"**
但是在我的模式中,它清楚地说
create_table "users", force: true do |t|
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.string "current_sign_in_ip"
t.string "last_sign_in_ip"
t.datetime "created_at"
t.datetime "updated_at"
t.string "provider"
t.string "uid"
end
如果我继续尝试
db:migrate
或db:migrate RAILS_ENV=development
,则什么也不会发生。有什么建议吗?
编辑:运行
rails console
(不是-e = test)结果是:#<ActiveRecord::Relation [#<User id: 1, email: "", encrypted_password: "", reset_password_token: nil, reset_password_sent_at: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, created_at: "2014-09-22 14:03:39", updated_at: "2014-09-22 14:03:39", provider: nil, uid: nil>]>
最佳答案
看来您尚未在测试环境中创建数据库。跑:
rake db:create RAILS_ENV=test
rake db:migrate RAILS_ENV=test
那应该解决它
