ActiveRecord::StatementInvalid: PG InFailedSqlTransaction

Question

I am trying to create an ActiveRecord Object.But I\'m getting this error while creating it.

(0.1ms)  ROLLBACK
ActiveRecord::StatementInvalid: PG::InFailedSql         


        

Answer 1

None of the other answers fix the root cause of the issue.

The problem is that when Postgres raises an exception, it poisons future transactions on the same connection.

The fix is to rollback the offending transaction:

begin
  ActiveRecord...do something...
rescue Exception => e
  puts "SQL error in #{ __method__ }"
  ActiveRecord::Base.connection.execute 'ROLLBACK'

  raise e
end

See reference.
