Overriding id on create in ActiveRecord

Question

Is there any way of overriding a model\'s id value on create? Something like:

Post.create(:id => 10, :title => \'Test\')

would be ide

Answer 1

This case is a similar issue that was necessary overwrite the id with a kind of custom date :

# in app/models/calendar_block_group.rb
class CalendarBlockGroup < ActiveRecord::Base
...
 before_validation :parse_id

 def parse_id
    self.id = self.date.strftime('%d%m%Y')
 end
...
end

And then :

CalendarBlockGroup.create!(:date => Date.today)
# => #

Callbacks works fine.

Good Luck!.
