Hi - Very new to RoR. I have looked around at different strategies
for handling shipping and billing addresses for an e-commerce
applications. What I am trying to do is to have a user registration
form where the user need to also fill out the default shipping
address. Ultimately, I would like for the users to be able to add
additional shipping address and billing addresses.
I am sort of going down the path outlined by ryanb's here and using
Single Table Inheritance where the shipping address and billing
address inherits from address class. Is this the best approach?
ryanb suggested something along the lines below:
Customer
has_many :addresses
has_many :orders
Address
belongs_to :customer
Order
belongs_to :customer
belongs_to :billing_address #...
belongs_to :shipping_address #...
Is this an instance where I need to use both STI and polymorphic
association?
Can someone walk through an example of what is needed to do this or a
strategy to accomplish this?
Here is what I have so far for the registration form:
************************************************
<% title "User Registration" %>
<div id="registration_leftcol">
<h1>Why Sign Up?</h1>
<ul>
<li>Faster checkout</li>
<li>Track your orders</li>
<li>View your order history</li>
<li>Receive email updates</li>
</ul>
<p>
<b>Already registered? <%= link_to 'Login here!', login_path %></
b>
</p>
</div>
<div id="registration_rightcol">
<h1>Your Info</h1>
<% form_for(@user) do |f| %>
<%= f.error_messages %>
<%= render :partial => 'form', :locals => { :f => f } %>
<%= render :partial => "addresses/address", :collection =>
@user.addresses %>
<p>
<%= image_submit_tag("/images/Register Button.jpg") %>
</p>
<% end %>
</div>
************************************************
I haven't created the order.rb model yet, but ryanb did suggest making
sure that...
"The billing_address_id column would go in the orders table. Same
with the shipping."
Is this the only table in the database that would contain this
column? Should they also exist in the address table or is this
handled by Rails through the type column? All so very confusing.
Here's my current code but I'm certain I'm missing some key concepts
here. I am providing some of the code below. Any help would be
greatly appreciated.
users_controller.rb
************************************************
class UsersController < ApplicationController
# GET /users
# GET /users.xml
before_filter :require_no_user, :only => [:new, :create]
before_filter :require_user, :only => [:show, :edit, :update]
@title = 'User Registration'
def index
@users = User.all
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @users }
end
end
# GET /users/1
# GET /users/1.xml
def show
#...@user = User.find(params[:id])
@user = @current_user
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @user }
end
end
# GET /users/new
# GET /users/new.xml
def new
@user = User.new
@user_session = UserSession.new
@user.addresses.build
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => @user }
end
end
# GET /users/1/edit
def edit
# @user = User.find(params[:id])
@user = @current_user
end
# POST /users
# POST /users.xml
def create
@user = User.new(params[:user])
respond_to do |format|
if @user.save
flash[:notice] = 'Registration successful.'
format.html { redirect_to(@user) }
format.xml { render :xml => @user, :status
=> :created, :location => @user }
else
format.html { render :action => "new" }
format.xml { render :xml => @user.errors, :status
=> :unprocessable_entity }
end
end
end
# PUT /users/1
# PUT /users/1.xml
def update
# @user = User.find(params[:id])
@user = @current_user
respond_to do |format|
if @user.update_attributes(params[:user])
flash[:notice] = 'Account was successfully updated.'
format.html { redirect_to(@user) }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => @user.errors, :status
=> :unprocessable_entity }
end
end
end
# DELETE /users/1
# DELETE /users/1.xml
def destroy
@user = User.find(params[:user])
@user.destroy
respond_to do |format|
format.html { redirect_to(users_url) }
format.xml { head :ok }
end
end
end
************************************************
user.rb model:
************************************************
class User < ActiveRecord::Base
acts_as_authentic
has_many :addresses
accepts_nested_attributes_for :addresses, :allow_destroy => true
def address_attributes=(address_attributes)
address_attributes.each do |attributes|
addresses.build(attributes)
end
end
How do I make the default registration address be the default
shipping_address? I am using address here but should it be
shipping_address? Should I use a hidden field to set the type and
modify the create section of the code?
