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>).

I try again with other ruby method
Folder1.create(:ID => @id, :CLIENT_NAME => @un, :TREE_NAME => @tn)

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

Other actions (e.g. Folder1.find(:all,:conditions => "ID
='"+Id.to_s+"'")) works good.

Smb know why Oracle return error #NoMethodError

why u use upper case name as the field name?
Please use lower case and try again:
folder = Folder.new()
folder.id= @id
folder.client_name = @un
folder.tree_name = @tn
folder.save()

I use upper case, because fields names in db have upper case
(
ID INTEGER,
CLIENT_NAME VARCHAR2(35 BYTE) NOT NULL,
TREE_NAME VARCHAR2(35 BYTE) NOT NULL,
)
---
I try lower case and got error : undefined method `id=' for
#<FolderTree:0x54060b0>
---

Does anybody have solution of this problem ?

It has no relation to the character case of field names in db. You'd better
use lower case string for the function name in Ruby.

How is your db migration file (001_create_fold_trees.rb
) for the FoldTree model like?

it's conetns of 001_create_folder_trees.rb :
class CreateFolderTrees < ActiveRecord::Migration
def self.up
create_table :folder_trees do |t|
end
end

def self.down
drop_table :folder_trees
end
end

That's the problem. You need to define columns for the folder_trees table
like this:

*def self.up
create_table :folder_trees do |t|*
* t.column :client_name, :string*
* t.column :tree_name, :string
end
end*
**

*Then run rake task "rake db:migrate" to create the table in db.*

Table structure in DB already exist, like this:
{
CLIENT_NAME VARCHAR2(35 BYTE) NOT NULL,
TREE_NAME VARCHAR2(35 BYTE) NOT NULL
}

You can ask for help from the rails-talk mailing list [
