How to lock multiple resources in RoR

Jul 27, 2024

When I tried to lock multiple records at one time, I noticed that the doc of Rails didn’t notice it.

ActiveRecord::Locking::Pessimistic

api.rubyonrails.org

accounts = Account.where(...)
account1 = accounts.detect { |account| ... }
account2 = accounts.detect { |account| ... }

I wanted to lock detected accounts without getting each one. However, I managed to do that in the project I’m belonging to.

How can we lock multiple records?

ActiveRecord::Base.transaction do
   locked_accounts = Account.where(
        id: ids,
      ).lock
   locked_accounts.save!
  end
end

We can do like this.
