Examples of RESTful API calls for E-commerce platforms

These examples are type 3 RESTful API requests and responses. The JSON-HAL specification is used to implement HATEOAS.

Some of the examples are based on my work as architect of the RESTful API at http://www.hautelook.com. All proprietary information has been removed.

# MOTIVATION:  As rails apps are growing, people are noticing the drawbacks
# of the ActiveRecord pattern.  Several apps I have seen, and several
# developers I have spoken to are looking towards other patterns for object
# persistence.  The major drawback with ActiveRecord is that the notion
# of the domain object is conflated with what it means to store/retrieve
# it in any given format (like sql, json, key/value, etc).
#
# This is an attempt to codify the Repository pattern in a way that would
# feel comfortable to beginner and seasoned Ruby developers alike.

# This simple lib help you to add state to a model without implementing boring functions for each state
# just add macro like "add_state 1, 'mystate'" to the definition of your ActiveRecord model
# this lib require a "state" field in the model
