From 8569126c2e52cdde6dba2dd86c9a8e802b0c5e4c Mon Sep 17 00:00:00 2001 From: Claire Date: Wed, 7 Jul 2021 21:13:30 +0200 Subject: [PATCH] Fix upgrade path from 3.4.0 (#16465) 3.4.1 dropped account_stats.lock_version, but in a way breaking the usual upgrade path by requiring services to be reloaded after the post-migrations. Indeed, `self.locking_column = nil` was not enough for Rails to ignore the `lock_version` column when preparing statements on application load, resulting in some ActiveRecord queries (typically those involving `includes(:account_stat)`) erroring out with: ActiveRecord::StatementInvalid (PG::UndefinedColumn: ERROR: column account_stats.lock_version does not exist --- app/models/account_stat.rb | 1 + 1 file changed, 1 insertion(+) diff --git a/app/models/account_stat.rb b/app/models/account_stat.rb index 44da4f0d00..e702fa4a44 100644 --- a/app/models/account_stat.rb +++ b/app/models/account_stat.rb @@ -15,6 +15,7 @@ class AccountStat < ApplicationRecord self.locking_column = nil + self.ignored_columns = %w(lock_version) belongs_to :account, inverse_of: :account_stat
