Rake db：种子耙中止！ ActiveRecord :: RecordInvalid：验证失败：电子邮件已被采用

Question

我是OneMonth学习条形支付的初学者。现在，我正在学习如何创建产品表并为数据库创建种子。一切都一帆风顺，到目前为止，直到我跑耙分贝之后遇到一个问题：种子

大卫 - MBP-2：one_month_stripe_payments DKP $耙分贝：种子 耙中止！ ActiveRecord :: RecordInvalid：验证失败：电子邮件已被采用 /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/validations.rb： 79：在raise_record_invalid' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/validations.rb:43:in保存！' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/attribute_methods/dirty.rb:29:in save!' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/transactions.rb:291:in block in save！' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/transactions.rb:351:in block in with_transaction_returning_status' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/connection_adapters/abstract/database_statements.rb:213:in交易' /Users/DKP /中的区块。 rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/connection_adapters/abstract/transaction.rb：184：在within_new_transaction' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/connection_adapters/abstract/database_statements.rb:213:in交易' /Users/DKP/.rvm/gems/ruby -2.3.0@global/gems/activerecord-4.2.5/lib/active_record/transactions.rb：220：在transaction' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/transactions.rb:348:in with_transaction_returning_status' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/ activerecord-4.2.5/lib/active_record/transactions.rb：291：在save!' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/persistence.rb:51:in创建！' /Users/DKP/Desktop/one_month/one_month_stripe_payments/db/seeds.rb:8:in <top (required)>' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activesupport-4.2.5/lib/active_support/dependencies.rb:268:in load' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activesupport-4.2.5 /lib/active_support/dependencies.rb:268:in block in load' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activesupport-4.2.5/lib/active_support/dependencies.rb:240:in load_dependency' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activesupport-4.2.5/lib/active_support/dependencies.rb： 268：load' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/railties-4.2.5/lib/rails/engine.rb:547:in load_seed' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/tasks/database_tasks.rb:250:in load_seed' /Users/DKP/.rvm/gems/ruby-2.3.0@global/gems/activerecord-4.2.5/lib/active_record/railties/databases.rake:183:in block（2）水平）' /Users/DKP/.rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in eval' /Users/DKP/.rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in' 任务：TOP => db：seed （请参阅完整跟踪，通过使用 - 跟踪）

我试过rake db：reset，然后rake：db migrate，然后再次rake db：seed。但我仍然有同样的错误。

任何人都可以帮助我解决这个问题吗？我感觉卡住了，我不知道该怎么做。

非常感谢！

Answer 1

当你做rake db:reset，什么轨道是rake db:drop - >rake db:create - >rake db:migrate - >rake db:seed。

你不需要再次rake db:seed。

你可以通过做rails c检查你的控制台，看看你的种子数据是否已经在里面。 Product.all

Answer 2

'电子邮件已被采纳'意味着你有一个已经存在的电子邮件记录。

执行Rails控制台并检查记录是否存在。 如果没有，请执行rake db：drop - > rake db：create - > rake db：migrate - > rake db：seed。这将解决您的问题。
