That’s what this post is for.

So on to the nitty gritty details.

Start with the RESTful Authentication Tutorial:

Follow the README to install, but READ THIS FIRST to fix the ExceptionLogger error Then follow these instructions to fix the OpenID plugin error Make sure you get your recaptcha keys for the config.yml, otherwise failed login attempts will bust your application. Fill out the config & database.yml files accordingly, run your database create & migrate rakes, fire up the server and make sure it looks good. Cool? Let’s move on: Define the objects Let’s begin by pointing out what, exactly, we’ll be building this application around: Galleries of Photos that Customers can order with a private Account provided to them by an Admin who can manage the galleries and review the Orders, which are also available to their respective customers. I will go through how to set up the following models like so:

• Galleries
  • has_many :photos
  • belongs_to :customer
  • title
  • acts_as_urlnameable (pretty URLs)
• Photos
  • belongs_to :gallery
  • paperclip attachment: image
• Customers
  • username, password, full name
• Orders
  • has_many :line_items
  • belongs_to :customer
• Line Items
  • belongs_to rder
  • quantity, size, price

So let’s build the Galleries first:

Then edit the Gallery model:

That’ll be fine for now. Let’s add the Photos model with paperclip image attached:

Now edit the Photo model as such:

You should read all about the paperclip gem if you need more info on this model. Basically, we’re telling it to allow image attachments to the Photo model. Customers can be the RESTful Authentication Tutorial User model, just need to add a couple things here:

Let’s worry about Orders and Line Items later. We’ll have to add a cart, too. I’ll cover it, but it is all derived from Agile Web Development with Ruby on Rails Third Edition

Run your rake db:migrate and confirm all is well. Delete the Galleries layout file so it uses the application layout.

Let’s go see http://localhost:3000/galleries and play around. Add a gallery and then go to edit it. This is where we’ll add SWFUpload. Follow Jim Neath’s advice for this.

You’ll want a photos controller:

The create method I use is:

I had no luck getting Jim Neath’s session fix working, so I put skip_before_filter :verify_authenticity_token in the Photos Controller. Bad? Yea, probably. I haven’t found a better way yet.

Add this code to app/views/galleries/edit.html.erb:

Which leads you to add the following partial: app/views/photos/_image.html.erb

We’ll worry about the destroy link later, let’s integrate swfupload. Download the latest copy of SWFUpload. Copy flash/swfupload.swf to public/flash (make directory first). Copy swfupload.js & upload.js (in Jim Neath’s demo app) to public/javascripts. Copy Jim Neath’s swfupload.css file to public/stylesheets. Copy Jim Neath’s images/icons folder to public/images.

Add this code to app/views/galleries/edit.html.erb:

Yep, a lot is going on there. Reload your galleries/edit page and see if it’s still working

Ok, so this gets you to a functioning online photo gallery. Up next will be adding user accounts, a shopping cart, ordering options, customers & paypal integration. Stay tuned!
