Insert new record in Oracle table with RoR

Hello all, it's part of my code on RoR ":

Case #1 Hello all, there is part of my code :       folder = Folder1.new()       folder.ID = @id       folder.CLIENT_NAME = @un       folder.TREE_NAME = @tn       folder.save()

when i test it on mySQL all work right, but when i try it with Oracle i got this error #NoMethodError (undefined method `ID=' for #<FolderTree:0x4bae7cc>).

Case #2 I try again with other RoR api method Folder1.create(:ID => @id, :CLIENT_NAME => @un, :TREE_NAME => @tn)

and again got error : #NoMethodError (undefined method `CLIENT_NAME=' for #<FolderTree:0x4baf6a4>)

Notes: 1. Field id not auto-increment (filled manually) 2. Folder1 it's model of folder table

It's exist table structure of folder1 model : { ID INTERGER CLIENT_NAME VARCHAR2(35 BYTE) NOT NULL, TREE_NAME VARCHAR2(35 BYTE) NOT NULL }

Does anybody know why is an error ? Or another path to insert new record.

Can you post the full class definition you have for Folder1? And FolderTree?

you use :ID instead of :id MySQL is not case sensitive (at least with it's column names) maybe oracle is?

same goes for :CLIENT_NAME etc
