Hey all, I created a seed task:
def books! books = Book.where(:type_id => Type.find_by_name('Fiction')).order('id') books.each do |book| @books = 4.times.map do |i| subbook! "#{book.book_num}-#{i}".to_s, :book_state => BookState[:available].id, :book => book end end puts "log it: #{@books.is_a?(Array)}" #array of book objects courtesy of map end def subbook!(book_num, options = {}) defaults = { :book_num => book_num } Subbook.create!(defaults.merge(options)) end My problem is when I create a subbook record, whatever auto incremented primary key it gets, I want to also assign it to another field of the same record called 'sequence'. So if the primary key of the record is 23, then the sequence should also be 23. But the record is not created yet, so it doesnt have an id yet. I tried doing this in subbook model: belongs_to :book before_create :add_sequence def add_sequence self.sequence = self.id end But that didn't do anything at all when running the seed task. Any idea how to update another field with id of record before that record is saved to database?
