Thank you very much, Rob ! I will add a unique index to Users#username column (I had one but without unique option).What about wrapping the call into transaction ? Will it be correct to call retry ? If I got it right, retry will take another call to
find_or_create by is really simple
def find_or_create_by(attributes, &block) find_by(attributes) || create(attributes, &block) end
I don't think you need any transaction here. If you hit retry - that's because there is a conflicting record.
if you retry find_or_create_by - then the find_by part will succeed (because there is a conflicting record.)
