当运行bin / delayed_job启动时，postgres没有连接

Question

When I run bin/delayed_job start , I get the following errors:

Job ActiveJob::QueueAdapters::DelayedJobAdapter::JobWrapper (id=30) FAILED (0 prior attempts) with ActiveRecord::StatementInvalid: PG::ConnectionBad: PQconsumeInput() server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

PG::UnableToSend: no connection to the server

Answer 1

通过将以下内容添加到config/initializers/delayed_job.rb

ActiveRecord::Base.connection.reconnect!
