In my database the id for a field is 810. RoR thinks that it is 809. My log file (below) shows that just before the insert it grabs the next sequence value. I dont think it should do that. This causes problems further down the line when trying to access the Person object. Development Log file : "SQL (0.016000) select people_seq.nextval id from dual Person Create (0.015000) INSERT INTO people (title, weight, mothers_maiden_name, shoe_size, middlename, person_type, username, firstname, height, person_id, createdby, expired, name_string, surname) VALUES('Mr', '100', '', 10, 'T', null, null, 'T', '', :id, 'Chris Richards', 0, null, 'T')" My Code (standard generated code): def create_person @person = Person.new(params[:person]) if @person.save flash[:notice] = 'Person was successfully created.' ..... else ...... end end Its wierd, ive used rails for weeks with no problems. Any ideas?

This is what i have done to solve it, but it is totally wrong/stupid: Notice "@person.id+=1" if @person.save @person.id+=1 #!!!!! flash[:notice] = 'Person was successfully created.' ... else ... end This makes me feel dirty!! anyone any ideas wtf is going on?

I'm using Oracle. I get this error when i try to use the person object: "Couldn't find Person with ID=825.0" It actually has an id of 826 in the DB. Strange. Thanks, Chris

Strange. > Not an Oracle user myself, so I can't help that much, but it might be worth checking the column type of the id field. Other than that, not sure.

Hi Chris, I´ve done some tests with Oracle and it worked perfectly well. I did only a small trick to avoid getting that decimal point on the ID: on the view we use :id => doc.id.round. ´s 2006/3/21, Chris <email@example.com>:

Do you have a trigger on the table that also fetches the ID from the sequence when you're inserting records? If so, you might want to modify the trigger so that if the new ID is passed in, to use it, otherwise grab a value from the sequence, something like: create or modify trigger mytable_bi before insert on mytable for each row if :new.id is null then insert into mytable values (myseq.nextval, ...) else insert into mytable values (:new.id, ...) endif end

Thanks Corey, I'm using a legacy DB and a trigger existed that grabbed the next value from the sequence. I never thought of that!! Chris
