 CouchRest Model is only properly tested on CouchDB version 1.0 or newer.
 
+*WARNING:* As of April 2011 and the release of version 1.1.0, the default model type key is 'type' instead of 'couchrest-type'. Simply updating your project will not work unless you migrate your data or set the configuration option in your initializers:

-    gem 'couchrest_model', :git => 'git://github.com/couchrest/couchrest_model.git'
+CouchRest Model is configured to work out the box with no configuration as long as your CouchDB instance is running on the default port (5984) on localhost. The default name of the database is either the name of your application as provided by the `Rails.application.class.to_s` call (with /application removed) or just 'couchrest' if none is available.
 
-### Setup
+The library will try to detect a configuration file at `config/couchdb.yml` from the Rails root or `Dir.pwd`. Here you can configuration your database connection in a Rails-like way:
 
-There is currently no standard way for telling CouchRest Model how it should access your database, this is something we're still working on. For the time being, the easiest way is to set a COUCHDB_DATABASE global variable to an instance of CouchRest Database, and call `use_database COUCHDB_DATABASE` in each model.

-    class Cat < CouchRest::Model::Base
-      property :name
-      property :birthday
-    end
+### Testing
 
-    @cat = Cat.new(:name => 'Felix', :birthday => 2.years.ago)
-    @cat.name        # 'Felix'
-    @cat.birthday.is_a?(Time)  # True!
-    @cat.save
-    @cat = Cat.find(@cat.id)
-    @cat.name        # 'Felix'
-    @cat.birthday.is_a?(Time)  # False!
-
-Properties create getters and setters similar to the following:
-
-    def name
-      read_attribute('name')
-    end
-
-    def name=(value)
-      write_attribute('name', value)
-    end
-
-Properties can also have a type which will be used for casting data retrieved from CouchDB when the attribute is set:
-
-    class Cat < CouchRest::Model::Base
-      property :name, String
-      property :last_fed_at, Time
-    end
-
-    @cat = Cat.new(:name => 'Felix', :last_fed_at => 10.minutes.ago)
-    @cat.last_fed_at.is_a?(Time)   # True!
-    @cat.save
-    @cat = Cat.find(@cat.id)
-    @cat.last_fed_at < 20.minutes.ago   # True!
-
-
-Boolean or TrueClass types will create a getter with question mark at the end:
-
-    class Cat < CouchRest::Model::Base
-      property :awake, TrueClass, :default => true
-    end
-
-    @cat.awake?   # true
-
-Adding the +:default+ option will ensure the attribute always has a value.
-
-A read-only property will only have a getter method, and its value is set when the document
-is read from the database. You can however update a read-only attribute using the `write_attribute` method:
-
-    class Cat < CouchRest::Model::Base
-      property :name, String
-      property :lives, Integer, :default => 9, :readonly => true  
-
-      def fall_off_balcony!
-        write_attribute(:lives, lives - 1)
-        save
-      end
-    end
-
-    @cat = Cat.new(:name => "Felix")
-    @cat.fall_off_balcony!
-    @cat.lives    # Now 8!
-
-Mass assigning attributes is also possible in a similar fashion to ActiveRecord:
-
-    @cat.attributes = { :name => "Felix" }
-    @cat.save
-
-Is the same as:
-
-    @cat.update_attributes(:name => "Felix")
-
-By default, attributes without a property will not be updated via the `#attributes=` method. This provents useless data being passed to database, for example from an HTML form. However, if you would like truely
-dynamic attributes, the `mass_assign_any_attribute` configuration option when set to true will 
-store everything you put into the `Base#attributes=` method.
-
-
-## Property Arrays
-
-An attribute may contain an array of data. CouchRest Model handles this, along
-with casting, by defining the class of the child attributes inside an Array:
-
-    class Cat < CouchRest::Model::Base
-      property :name, String
-      property :nicknames, [String]
-    end
-
-By default, the array will be ready to use from the moment the object as been instantiated:
-
-    @cat = Cat.new(:name => 'Fluffy')
-    @cat.nicknames << 'Buffy'
-
-    @cat.nicknames == ['Buffy']
-
-When anything other than a string is set as the class of a property, the array will be converted
-into special wrapper called a CastedArray. If the child objects respond to the `casted_by` method
-(such as those created with CastedModel, below) it will contain a reference to the parent.
-
-## Casted Models
-
-CouchRest Model allows you to take full advantage of CouchDB's ability to store complex 
-documents and retrieve them using the CastedModel module. Simply include the module in
-a Hash (or other model that responds to the [] and []= methods) and set any properties
-you'd like to use. For example:
-
-    class CatToy < Hash
-      include CouchRest::Model::CastedModel
-
-      property :name, String
-      property :purchased, Date
-    end
-
-    class Cat < CouchRest::Model::Base
-      property :name, String
-      property :toys, [CatToy]
-    end
-
-    @cat = Cat.new(:name => 'Felix', :toys => [{:name => 'mouse', :purchased => 1.month.ago}])
-    @cat.toys.first.class == CatToy
-    @cat.toys.first.name == 'mouse'
-
-Any hashes sent to the property will automatically be converted:
-
-    @cat.toys << {:name => 'catnip ball'}
-    @cat.toys.last.is_a?(CatToy) # True!
-
-To use your own classes they *must* be defined before the parent uses them otherwise 
-Ruby will bring up a missing constant error. To avoid this, or if you have a really simple array of data
-you'd like to model, CouchRest Model supports creating anonymous classes:
-
-    class Cat < CouchRest::Model::Base
-      property :name, String
-
-      property :toys do
-        property :name, String
-        property :rating, Integer
-      end
-    end
-
-    @cat = Cat.new(:name => 'Felix', :toys => [{:name => 'mouse', :rating => 3}, {:name => 'catnip ball', :rating => 5}])
-    @cat.toys.last.rating == 5
-    @cat.toys.last.name == 'catnip ball'
-
-Anonymous classes will *only* create arrays of objects. If you're more of the traditional type, a block parameter
-can be provided allowing you to use this variable before each method call inside the anonymous class. This is useful
-if you need to access variables outside of the block.
-
-## Views
-
-CouchDB views can be quite difficult to get grips with at first as they are quite different from what you'd expect with SQL queries in a normal Relational Database. Checkout some of the [CouchDB documentation on views](http://wiki.apache.org/couchdb/Introduction_to_CouchDB_views) to get to grips with the basics. The key is to remember that CouchDB will only generate indexes from which you can extract consecutive rows of data, filtering other than between two points in a data set is not possible.
-
-CouchRest Model has great support for views, and since version 1.1.0 we added support for a View objects that make accessing your data even easier. 
-
-### The Old Way
-
-Here's an example of adding a view to our Cat class:
-
-    class Cat < CouchRest::Model::Base
-      property :name, String
-      property :toys, [CatToy]
-
-      view_by :name
-    end
-
-The `view_by` method will create a view in the Cat's design document called "by_name". This will allow searches to be made for the Cat's name attribute. Calling `Cat.by_name` will send a query of to the database and return an array of all the Cat objects available. Internally, a map function is generated automatically and stored in CouchDB's design document for the current model, it'll look something like the following:
-
-    function(doc) {
-      if (doc['couchrest-type'] == 'Cat' && doc['name']) {
-        emit(doc.name, null);
-      }
-    }
-
-By default, a special view called `all` is created and added to all couchrest models that allows you access to all the documents in the database that match the model. By default, these will be ordered by each documents id field.
-
-It is also possible to create views of multiple keys, for example:
-
-    view_by :birthday, :name
-
-This will create an view of all the cats' birthdays and their names called `by_birthday_and_name`.
-
-Sometimes the automatically generate map function might not be sufficient for more complicated queries. To customize, add the :map and :reduce functions when creating the view:
-
-    view_by :tags,
-      :map =>
-        "function(doc) {
-          if (doc['model'] == 'Post' && doc.tags) {
-            doc.tags.forEach(function(tag){
-              emit(doc.tag, 1);
-            });
-          }
-        }",
-      :reduce =>
-        "function(keys, values, rereduce) {
-          return sum(values);
-        }"
-
-Calling a view will return document objects by default, to get access to the raw CouchDB result add the `:raw => true` option to get a hash instead. Custom views can also be queried with `:reduce => true` to return reduce results. The default is to query with `:reduce => false`.
- 
-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.
-
-### View Objects
-
-Since CouchRest Model 1.1.0 it is now possible to create views that return objects chainable objects, similar to those you'd find in the Sequel Ruby library or Rails 3's Arel. Heres an example of creating a few views:
-
-    class Post < CouchRest::Model::Base
-      property :title
-      property :body
-      property :posted_at, DateTime
-      property :tags, [String]
-
-      design do
-        view :by_title
-        view :by_posted_at_and_title
-        view :tag_list,
-          :map =>
-            "function(doc) {
-              if (doc['model'] == 'Post' && doc.tags) {
-                doc.tags.forEach(function(tag){
-                  emit(doc.tag, 1);
-                });
-              }
-            }",
-          :reduce =>
-            "function(keys, values, rereduce) {
-              return sum(values);
-            }"
-      end
-
-You'll see that this new syntax requires all views to be defined inside a design block. Unlike the old version, the keys to be used in a query are determined from the name of the view, not the other way round. Acessing data is the fun part:
-
-    # Prepare a query:
-    view = Post.by_posted_at_and_title.skip(5).limit(10)
-
-    # Fetch the results:
-    view.each do |post|
-      puts "Title: #{post.title}"
-    end
-
-    # Grab the CouchDB result information with the same object:
-    view.total_rows   => 10
-    view.offset       => 5
-
-    # Re-use and add new filters
-    filter = view.startkey([1.month.ago]).endkey([Date.current, {}])
-
-    # Fetch row results without the documents:
-    filter.rows.each do |row|
-      puts "Row value: #{row.value} Doc ID: #{row.id}"
-    end
-
-    # Lazily load documents (take last row from previous example):
-    row.doc      => Fetch last Post document from database
-
-    # Using reduced queries is also easy:
-    tag_usage = Post.tag_list.reduce.group_level(1)
-    tag_usage.rows.each do |row|
-      puts "Tag: #{row.key}  Uses: #{row.value}"
-    end
-
-#### Pagination
-
-The view objects have built in support for pagination based on the [kaminari](https://github.com/amatsuda/kaminari) gem. Methods are provided to match those required by the library to peform pagination.
-
-For your view to support paginating the results, it must use a reduce function that provides a total count of the documents in the result set. By default, auto-generated views include a reduce function that supports this.
-
-Use pagination as follows:
-
-    # Prepare a query:
-    @posts = Post.by_title.page(params[:page]).per(10)
-    
-    # In your view, with the kaminari gem loaded:
-    paginate @posts
-
-
-## Assocations
-
-Two types at the moment:
-
-    belongs_to :person
-
-    collection_of :tags
-
-This is a somewhat controvesial feature of CouchRest Model that some document database purists may cringe at. CouchDB does not yet povide many features to support relationships between documents but the fact of that matter is that its a very useful paradigm for modelling data systems.
-
-In the near future we hope to add support for a `has_many` relationship that takes of the _Linked Documents_ feature that arrived in CouchDB 0.11.
-
-### Belongs To
-
-Creates a property in the document with `_id` added to the end of the name of the foreign model with getter and setter methods to access the model. 
-
-Example:
-
-    class Cat < CouchRest::Model::Base
-      belongs_to :mother
-      property :name
-    end
-
-    kitty = Cat.new(:name => "Felix")
-    kitty.mother = Mother.find_by_name('Sophie')
-
-Providing a object to the setter, `mother` in the example will automagically update the `mother_id` attribute. Retrieving the data later is just as expected:
-
-    kitty = Cat.find_by_name "Felix"
-    kitty.mother.name == 'Sophie'
-
-Belongs_to accepts a few options to add a bit more felxibility:
-
-* `:class_name` - the camel case string name of the class used to load the model.
-* `:foreign_key` - the name of the property to use instead of the attribute name with `_id` on the end.
-* `:proxy` - a string that when evaluated provides a proxy model that responds to `#get`.
-
-The last option, `:proxy` is a feature currently in testing that allows objects to be loaded from a proxy class, such as `ClassProxy`. For example:
-
-    class Invoice < CouchRest::Model::Base
-      attr_accessor :company
-      belongs_to :project, :proxy => 'self.company.projects'
-    end
-
-A project instance in this scenario would need to be loaded by calling `#get(project_id)` on `self.company.projects` in the scope of an instance of the Invoice. We hope to document and work on this powerful feature in the near future.
-
-
-### Collection Of
-
-A collection_of relationship is much like belongs_to except that rather than just one foreign key, an array of foreign keys can be stored. This is one of the great features of a document database. This relationship uses a proxy object to automatically update two arrays; one containing the objects being used, and a second with the foreign keys used to the find them.
-
-The best example of this in use is with Labels:
-
-    class Invoice < CouchRest::Model::Base
-      collection_of :labels
-    end
-
-    invoice = Invoice.new
-    invoice.labels << Label.get('xyz')
-    invoice.labels << Label.get('abc')
-
-    invoice.labels.map{|l| l.name} # produces ['xyz', 'abc']
-
-See the belongs_to relationship for the options that can be used. Note that this isn't especially efficient, a `get` is performed for each model in the array. As with a has_many relationship, we hope to be able to take advantage of the Linked Documents feature to avoid multiple requests.
-
-
-## Validations
-
-CouchRest Model automatically includes the new ActiveModel validations, so they should work just as the traditional Rails validations. For more details, please see the ActiveModel::Validations documentation.
-
-CouchRest Model adds the possibility to check the uniqueness of attributes using the `validates_uniqueness_of` class method, for example:
-
-    class Person < CouchRest::Model::Base
-      property :title, String
-     
-      validates_uniqueness_of :title
-    end
-
-The uniqueness validation creates a new view for the attribute or uses one that already exists. You can
-specify a different view using the `:view` option, useful for when the `unique_id` is specified and
-you'd like to avoid the typical RestClient Conflict error:
-
-    unique_id :code
-    validates_uniqueness_of :code, :view => 'all'
-
-Given that the uniqueness check performs a request to the database, it is also possible to include a `:proxy` parameter. This allows you to call a method on the document and provide an alternate proxy object.
-
-Examples:
-
-    # Same as not including proxy:
-    validates_uniqueness_of :title, :proxy => 'class'
-    
-    # Person#company.people provides a proxy object for people
-    validates_uniqueness_of :title, :proxy => 'company.people'
-
-
-A really interesting use of `:proxy` and `:view` together could be where you'd like to ensure the ID is unique between several types of document. For example:
-
-    class Product < CouchRest::Model::Base
-      property :code
-
-      validates_uniqueness_of :code, :view => 'by_product_code'
-
-      view_by :product_code, :map => "
-        function(doc) {
-          if (doc['couchrest-type'] == 'Product' || doc['couchrest-type'] == 'Project') {
-            emit(doc['code']);
-          }
-        }
-      "
-    end
-
-    class Project < CouchRest::Model::Base
-      property :code
-
-      validates_uniqueness_of :code, :view => 'by_product_code', :proxy => 'Product'
-    end
-
-Pretty cool!
-
-
-## Configuration
-
-CouchRest Model supports a few configuration options. These can be set either for the whole Model code
-base or for a specific model of your chosing. To configure globally, provide something similar to the 
-following in your projects loading code:
-
-    CouchRest::Model::Base.configure do |config|
-      config.mass_assign_any_attribute = true
-      config.model_type_key = 'couchrest-type'
-    end
-
-To set for a specific model:
-
-   class Cat < CouchRest::Model::Base
-     mass_assign_any_attribute true
-   end
-
-Options currently avilable are:
-
- * `mass_assign_any_attribute` - false by default, when true any attribute may be updated via the update_attributes or attributes= methods.
- * `model_type_key` - 'couchrest-type' by default, is the name of property that holds the class name of each CouchRest Model.
-
-
-## Notable Issues
-
-None at the moment...
-
-
-## Testing
-
-The most complete documentation is the spec/ directory. To validate your CouchRest install, from the project root directory run `rake`, or `autotest` (requires RSpec and optionally ZenTest for autotest support).
