I'm basically just trying to validate the Users.state_id field. The Users table holds the FK to States as user.state_id, where there is a one-to-many between States and Users.
# state.rb: class State < ActiveRecord::Base has_many :users end
# user.rb: class User < ActiveRecord::Base ... belongs_to :state ... validates_presence_of :state_id validates_associated :state ... end
# user_controller.rb: class UserController < ApplicationController ... def signup ... @user = User.new(params[:user]) return unless request.post? @user.save! self.current_user = @user redirect_back_or_default(:controller => '/user', :action => 'index') flash[:notice] = "Thanks for signing up!" rescue ActiveRecord::RecordInvalid render :action => 'signup' end end
signup.rhtml: ... <%= error_messages_for :user %> <% form_for :user, :url => {:action => "signup" } do |f| -%> ... <%= f.collection_select :state_id, State.find_all, :id, :name, {:include_blank => true}, {:style => 'background-color: rgb(255, 255, 160);', :class => 'form-txt2'} %> ...
