Custom Primary Key, Using Primary Key in Form gives "before_


#1

Hi guys,

I’ve got a problem here which i need help from the pro’s in this mailing
list

I have a legacy app where the User table has a custom structure where
“User_id” (username) is the primary key as well as the username used
to log in

User.rb (model)
class User < ActiveRecord::Base
set_table_name “cmf901”
set_primary_key “user_id”
end

Login Controller
class LoginController < ApplicationController
def login
@user = User.new
end
end

When creating a Login form (login.rhtml)
<%= start_form_tag :action => “process” %>
<%= text_field ‘user’, ‘user_id’, :MAXLENGTH =>“10” %>
<%= text_field ‘user’, ‘user_password’, :MAXLENGTH =>“20” %>
<%= submit_tag “Login” %>
<%= end_form_tag %>

I get an error

NoMethodError in Login#login

Showing app/views/login/login.rhtml where line #11 raised:

undefined method `user_id_before_type_cast’ for #User:0x3cb61e8

Extracted source (around line #11):

8:
9:


10: Username
11: <%= text_field ‘user’, ‘user_id’, :MAXLENGTH =>“10” %>
12:
13:
14: Password

All i want to do is use the standard rails way to create a login
form(used in Scaffold to create new/update) and do some authentication
