我想删除一个生产数据库,以便重新开始。当我从Rails 4升级到Rails 5时,它现在会防止意外删除生产数据库。当我运行rake db:reset
时,它会显示以下错误消息。
/app# rake db:reset
ActiveRecord::SchemaMigration Load (1.8ms) SELECT "schema_migrations".* FROM "schema_migrations"
(1.6ms) SELECT "ar_internal_metadata"."value" FROM "ar_internal_metadata" WHERE "ar_internal_metadata"."key" = $1 [["key", :environment]]
ActiveRecord::SchemaMigration Load (0.2ms) SELECT "schema_migrations".* FROM "schema_migrations"
(0.3ms) SELECT "ar_internal_metadata"."value" FROM "ar_internal_metadata" WHERE "ar_internal_metadata"."key" = $1 [["key", :environment]]
ActiveRecord::SchemaMigration Load (0.3ms) SELECT "schema_migrations".* FROM "schema_migrations"
(0.2ms) SELECT "ar_internal_metadata"."value" FROM "ar_internal_metadata" WHERE "ar_internal_metadata"."key" = $1 [["key", :environment]]
rake aborted!
ActiveRecord::ProtectedEnvironmentError: You are attempting to run a destructive action against your 'production' database.
If you are sure you want to continue, run the same command with the environment variable:
DISABLE_DATABASE_ENVIRONMENT_CHECK=1
/usr/local/bundle/gems/activerecord-5.0.0.1/lib/active_record/tasks/database_tasks.rb:51:in `check_protected_environments!'
/usr/local/bundle/gems/activerecord-5.0.0.1/lib/active_record/railties/databases.rake:11:in `block (2 levels) in <top (required)>'
/usr/local/bundle/gems/rake-11.3.0/exe/rake:27:in `<top (required)>'
Tasks: TOP => db:reset => db:drop => db:check_protected_environments
(See full trace by running task with --trace)
它说我在命令中添加环境变量DISABLE_DATABASE_ENVIRONMENT_CHECK=1应该能够起作用,但事实上并没有。我运行它,但什么也没发生。
<606723-x9dh4:/app# DISABLE_DATABASE_ENVIRONMENT_CHECK=1 rake db:reset
ActiveRecord::SchemaMigration Load (1.6ms) SELECT "schema_migrations".* FROM "schema_migrations"
有人知道我做错了什么吗?感谢帮助!
更新:
我的服务器使用kubernetes部署。我猜测我无法重置数据库,因为服务器正在运行。
RAILS_ENV=production DISABLE_DATABASE_ENVIRONMENT_CHECK=1 bin/rails db:reset
