我在第9章的ruby on rails教程，我在最後一分鐘遇到問題。一切正常在我的網頁上，但不是在heroku上。 下面是他說的步驟：ActiveRecord驗證失敗在Heroku上運行的種子
$ git push heroku
$ heroku pg:reset DATABASE
$ heroku run rake db:migrate
$ heroku run rake db:seed
$ heroku restart
當我運行rake db:seed
Running rake db:seed on radiant-peak-3596... up, run.3507
ActiveRecord::SchemaMigration Load (2.2ms) SELECT "schema_migrations".* FROM "schema_migrations"
(4.6ms) BEGIN
User Exists (8.1ms) SELECT 1 AS one FROM "users" WHERE LOWER("users"."email") = LOWER('[email protected]') LIMIT 1
(3.8ms) ROLLBACK

seed.rb
User.create!(name: "example user",
email: "[email protected]",
password: "foobar",
password_confirmation: "foobar",
admin: true)
99.times do |n|
name = Faker::Name.name
email = "example-#{n+1}@aol.org"
password = "password"
User.create!(name: name,
email: email,
password: password,
password_confirmation: password)
end
我已經安裝了寶石，它運行完美，但Heroku的是另一種案件。
謝謝！
你的seed.rb文件是什麼樣子的？你真的使用Faker作爲你的種子世代的一部分嗎？看起來像你正在對用戶example @ hotmail.com進行硬編碼。似乎不像faker會產生什麼 –
@LeoCorrea嗨！是的，它硬編碼！它看起來像這樣。 讓我編輯 –
我假設你的數據沒有被重置，或者你正在運行'rake db：seed'兩次。這就是你的種子失敗的原因，因爲你試圖創建硬編碼的用戶兩次，驗證失敗。 –
