Hi there,

This might be a stupid questions but I wanted to know what happens if two users edit some data at once and then both click submit at the same time, I assumed Rails handled requests one after the other and so someone would get an error message but is this correct?

Thanks

(Once one person has edited data I dont want it to be accessible or editable anymore)
