I have a before_save in my model

before saving the record to the database...I'd like to print out the autoincremented ID that will be inserted. My table has a column id in it.

I tried

before_save :printId

def printId
   puts "ID that will be inserted is: " + self.id
end

this does not work...

  • Where would you like such a printed statement to show up? in the console? in a view?

  • The question is: What do you need it for? If you need it beforehand for some reason, probably something is wrong with your application design or your understandings of ActiveRecord.

Try after_save.

  • As mentioned by Beerlington, the id is nil until save occurs.

The autoincrement ID does not exist for an ActiveRecord object until it has been saved. It's possible to get the next autoincrement ID for a table, but this doesn't guarantee that the ID will be given to your object when saved since another record may have been added in the meantime.
