!  Customization

!  Extendable

!  Less Prerequisites

Override views

!   There are two ways to do this:

1.  Using Deface

Deface is a standalone Rails 3 library that enables you to customize Erb templates without needing to directly edit the underlying view file. Deface allows you to use standard CSS3 style selectors to target any element (including Ruby blocks), and perform an action against all the matching elements. Now the official repo is located at spree/deface.

2. Template replacement

Sometimes the customization required to a view are so substantial that using a Deface override seems impractical. Spree also supports the duplication of views within an application or extension that will completely replace the file of the same name in Spree.

Using Deface-Example

Using Deface-Example

If you wanted to insert some code just before the #registration div on the page you would define an override as follows:

Note: the :name key is important! 1.  Locate the override; 2.  Disable default overrides from Spree extensions;

Deface: locate overrides

Deface: disable overrides

Override controllers/models

!  Logic customization:

1. Extending Classes

2. Overriding Controller Action Responses

3. Product Images Styles

Extending Classes

!   Adding a custom method to the Product model: app/models/product_decorator.rb

Extending Classes

!   Adding a custom action to the ProductsController:

app/controllers/products_controller_decorator.rb

Magic: decorator

config/application.rb

Overriding Controller Action Responses ! respond_override

The respond_override method is used to customize the response from any action, and is built on top of Rails 3’s respond_with method.

Product Images

! Imagemagick

!   Paperclip

!   Image Model

Problems:

styles

Other Customizations

!   Asset Customization:

Through regular overriding.

!   Checkout Flow:

State machine allows you to hook transitions.

To add or remove steps to the checkout flow, you must re-define the entire checkout flow.
