Where can I define the method ''tbluser'' in this error?
NoMethodError in Tblregisteredphone#list
Showing app/views/tblregisteredphone/list.rhtml where line #23 raised:
undefined method `tbluser'' for #<Tblregisteredphone:0x375c778>

24: :action => "list",
25: :tbluser => "#{tblregisteredphone.tbluser.txtForename}"
%>
26: </td>
The tblregisteredphones model and controller are as follows:
Model:
class Tblregisteredphone < ActiveRecord::Base
set_table_name "tblregisteredphones"
belongs_to :user,
:foreign_key => "intUserID"
set_primary_key(:TblRegisteredPhonesID)
end
Controller:
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
Thank you,

It would help to see the model and schema for the user table, which is where the problem seems to be. I notice that you say "belongs_to :user" and then you try to reference tblregisteredphone.tbluser.txtForename, though. Shouldn''t it be tblregisteredphone.user.txtForename instead? Also, is the user table called users or tblusers, and how is it referred to in its model? You really should name things more consistently. It''s not a good sign when you''re confused by your own naming convention. If these are legacy tables and you''re aliasing them in the models to simpler names, you should pick one way to do it and stick to it throughout to prevent more problems like this, nu?

Hi Steve,
My mistake, it was meant to say "belongs_to :tbluser", which
I''ve
changed in the model and am now getting a slightly different error as
below.
NoMethodError in Tblregisteredphone#list
Showing app/views/tblregisteredphone/list.rhtml where line #23 raised:
You have a nil object when you didn''t expect it!
The error occured while evaluating nil.txtForename
Extracted source (around line #23):
20: </font>
21: </td>
22: <td>
23: <%= link_to tblregisteredphone.tbluser.txtForename,
24: :action => "list",
25: :tbluser => "#{tblregisteredphone.tbluser.txtForename}"
%>
26: </td>
The users table is called "tblusers" and the model is as follows:
class Tbluser < ActiveRecord::Base
set_table_name "tblusers"
has_many :tblregisteredphones
set_primary_key(:TblUsersID)
end
I am using legacy tables and am new to rails so am finding it difficult
to understand how the aliases work. Once I''ve set the aliases, can I
then refer to them everywhere else (controller and rhtml files) as as
the alias name? I had no problems creating this database as a test using
the normal rails naming conventions, but since using the legacy schema,
I have been unable to get it to work properly.
Thank you for your help, it is much appreciated.

As I''m new to rails and still learning my way, I''m not sure why the method is not defined or where it should be defined. My model is as follows: class Registeredphone < ActiveRecord::Base set_table_name "tblregisteredphones" set_primary_key "TblRegisteredPhonesID" belongs_to :user, :foreign_key => "intUserID" end Is this where I should be defining ''user_id''? The foreign key in this table (intUserID)is linked to the id in the user table (TblUserID) and has been aliased due to difficult naming conventions used in this legacy schema. Do I need to do more, or is this alias method correct?

ActiveRecord is expectinb your registered_phone table to contain a column named ''user_id''. It seems you are using ''intUserID'' to keep track of the relationship, so if you change ''user_id'' in your view to ''intUserID'', it should work.
