## CouchRest::Model
CouchRest::Model is a module designed along the lines of DataMapper::Resource.
By subclassing, suddenly you get all sorts of powerful sugar, so that working
with CouchDB in your Rails or Merb app is no harder than working with the
standard SQL alternatives. See the CouchRest::Model documentation for an
example article class that illustrates usage.
CouchRest::Model will be removed from this package.
CouchRest::Model has been deprecated and replaced by CouchRest::ExtendedDocument

module CouchRest
# = CouchRest::Model - Document modeling, the CouchDB way
#
# CouchRest::Model provides an ORM-like interface for CouchDB documents. It
# avoids all usage of <tt>method_missing</tt>, and tries to strike a balance
# between usability and magic. See CouchRest::Model#view_by for
# documentation about the view-generation system.
#
# ==== Example
#
# This is an example class using CouchRest::Model. It is taken from the
# spec/couchrest/core/model_spec.rb file, which may be even more up to date
# than this example.
#
# class Article < CouchRest::Model
# use_database CouchRest.database!('http://127.0.0.1:5984/couchrest-model-test')
# unique_id :slug
#
# view_by :date, :descending => true
# view_by :user_id, :date
#
# view_by :tags,
# :map =>
# "function(doc) {
# if (doc['couchrest-type'] == 'Article' && doc.tags) {
# doc.tags.forEach(function(tag){
# emit(tag, 1);
# });
# }
# }",
# :reduce =>
# "function(keys, values, rereduce) {
# return sum(values);
# }"
#
# key_writer :date
# key_reader :slug, :created_at, :updated_at
# key_accessor :title, :tags
#
# timestamps!
#
# before(:create, :generate_slug_from_title)
# def generate_slug_from_title
# self['slug'] = title.downcase.gsub(/[^a-z0-9]/,'-').squeeze('-').gsub(/^\-|\-$/,'')
# end
# end
#
# ==== Examples of finding articles with these views:
#
# * All the articles by Barney published in the last 24 hours. Note that we
# use <tt>{}</tt> as a special value that sorts after all strings,
# numbers, and arrays.
#
# Article.by_user_id_and_date :startkey => ["barney", Time.now - 24 * 3600], :endkey => ["barney", {}]
#
# * The most recent 20 articles. Remember that the <tt>view_by :date</tt>
# has the default option <tt>:descending => true</tt>.
#
# Article.by_date :limit => 20
#
# * The raw CouchDB view reduce result for the custom <tt>:tags</tt> view.
# In this case we'll get a count of the number of articles tagged "ruby".
#
# Article.by_tags :key => "ruby", :reduce => true
#

#
# class Post < CouchRest::Model
#
# key_accessor :title, :body, :author
#
# cast :author, :as => 'Author'
#
# end
#
# post.author.class #=> Author
#
# Using the same example, if a Post should have many Comments, we
# would declare it like this:
#
# class Post < CouchRest::Model
#
# key_accessor :title, :body, :author, comments
#
# cast :author, :as => 'Author'
# cast :comments, :as => ['Comment']
#
# end
#
# post.author.class #=> Author
# post.comments.class #=> Array
# post.comments.first #=> Comment

# this can be used to enforce eg: uniq usernames. Note that this id
# must be globally unique across all document types which share a
# database, so if you'd like to scope uniqueness to this class, you
# should use the class name as part of the unique id.

end
# Define a CouchDB view. The name of the view will be the concatenation
# of <tt>by</tt> and the keys joined by <tt>_and_</tt>
#
# ==== Example views:
#
# class Post
# # view with default options
# # query with Post.by_date
# view_by :date, :descending => true
#
# # view with compound sort-keys
# # query with Post.by_user_id_and_date
# view_by :user_id, :date
#
# # view with custom map/reduce functions
# # query with Post.by_tags :reduce => true
# view_by :tags,
# :map =>
# "function(doc) {
# if (doc['couchrest-type'] == 'Post' && doc.tags) {
# doc.tags.forEach(function(tag){
# emit(doc.tag, 1);
# });
# }
# }",
# :reduce =>
# "function(keys, values, rereduce) {
# return sum(values);
# }"
# end
#
# <tt>view_by :date</tt> will create a view defined by this Javascript
# function:
#
# function(doc) {
# if (doc['couchrest-type'] == 'Post' && doc.date) {
# emit(doc.date, null);
# }
# }
#
# It can be queried by calling <tt>Post.by_date</tt> which accepts all
# valid options for CouchRest::Database#view. In addition, calling with
# the <tt>:raw => true</tt> option will return the view rows
# themselves. By default <tt>Post.by_date</tt> will return the
# documents included in the generated view.
#
# CouchRest::Database#view options can be applied at view definition
# time as defaults, and they will be curried and used at view query
# time. Or they can be overridden at query time.
#
# Custom views can be queried with <tt>:reduce => true</tt> to return
# reduce results. The default for custom views is to query with
# <tt>:reduce => false</tt>.
#
# Views are generated (on a per-model basis) lazily on first-access.
# This means that if you are deploying changes to a view, the views for
# that model won't be available until generation is complete. This can
# take some time with large databases. Strategies are in the works.
#
# To understand the capabilities of this view system more compeletly,
# it is recommended that you read the RSpec file at
# <tt>spec/core/model_spec.rb</tt>.
