Can anyone help?What does the code for the "new" method in your controller say? I can only assume that @tblusers isn''t being set properly there, but if you post the method then we can help more. Thanks, David

Pretty easy to fix :-) David

I''m getting the following error and have checked and double checked all
my table and field names are correct. Only the field names have
uppercase letters in them. Where am I going wrong?

Hi Alana ~ Are you sure you have an object tblregisteredphone that has data? If that is one of your models, you need to create an instance of that model. Might try putting <%= debug tblregisteredphone %> in your view to see if the object is being created. I would need to see what the controller is doing to offer some more help. ~ Ben On 4/7/06, Alana <alana@c4l.co.uk> wrote:> > I''m getting the following error and have checked and double checked all > my table and field names are correct.

Hi Ben,
tblregisteredphone definitely has data in it. The model for it is as
follows:
class Tblregisteredphone < ActiveRecord::Base
belongs_to :tbluser,
set_primary_key(:TblRegisteredPhonesID)
end
The model for the table it is related to (tbluser) is as follows:
class Tbluser < ActiveRecord::Base
has_many :tblregisteredphones
set_primary_key(:TblUsersID)
end
Thanks for your help,
Alana

Hi, I created a test database using the conventional rails naming such as "id" for primary key and "tblname_id" for foreign keys. I then recreated the rails database for an existing database and had to use their primary and foreign key names. Since then, even though I have set the primary and foreign keys in the table models, I have been getting errors such as this no method error. Can anyone please help me with this?

You didn''t initialize Tblregisteredphone[tbluser_id]. What does your controller look like? -- Ray
Hi Ray,> Tblregisteredphone.tbluser is nil. > > You didn''t initialize Tblregisteredphone[tbluser_id]. > > What does your controller look like?My tblregisteredphone controller is as follows: class Tblregisteredphone < ActiveRecord::Base set_table_name "tblregisteredphones" belongs_to :tbluser, :foreign_key => "intUserID" set_primary_key(:TblRegisteredPhonesID) end "tbluser" has a primary key called "TblUsersID" and the foreign key in "tblregisteredphones" is called "intUserID".

We need to see your controller, and probably your data too. -- Ray
Sorry, the controller is as follows. What data do you need? class TblregisteredphoneController < ApplicationController layout "standard-layout" scaffold :tblregisteredphone def delete Tblregisteredphone.find(@params[''id'']).destroy redirect_to :action => ''list'' end def create @tblregisteredphone = Tblregisteredphone.new(@params[''tblregisteredphone'']) @tblregisteredphone.txtregisterdatetime = Time.now if @tblregisteredphone.save redirect_to :action => ''list'' else render_action ''new'' end end def new @tblregisteredphone = Tblregisteredphone.new @tbluser = Tbluser.find_all end def list @tbluser = @params[''tbluser''] @tblregisteredphones = Tblregisteredphone.find_all end def edit @tblregisteredphone = Tblregisteredphone.find(@params["id"]) @tbluser = Tbluser.find_all end end Alana -- Posted via http://www.ruby-forum.com/.

This line is in my view: <% @tblregisteredphones.each do |tblregisteredphone| %> Is this correct? 2. How do I initialize intUserID (the foreign key in tblregistered phones) and is this the correct naming convention? My tables are as follows: "tblusers" - primary key "TblUsersID" "tblregisteredphones" - primary key "TblRegisteredPhonesID" - foreign key "intUserID" 3. All of the entries have a non-null intUserID.

This could be because your registeredphones table doesn''t have a user_id column, or because you didn''t define a user_id method in your Registeredphone model. -- Ray
