If your project is still running Rails 2.3, you'll have to continue using ExtendedDocument as
it is not possible to load ActiveModel into programs that do not use ActiveSupport 3.0.
CouchRest Model only supports CouchDB 0.10.0 or newer.
CouchRest Model is only tested on CouchDB 1.0.0 or newer.
## Install
### From Gem
### Gem
CouchRest Model depends on Rails 3's ActiveModel which has not yet been released. You'll need to add
`--pre` to the end of the gem install until the dependencies are stable:
$ sudo gem install couchrest_model --pre

## Properties
Only attributes with a property definition will be stored be CouchRest Model (as opposed
to a normal CouchRest Document which will store everything). To help prevent confusion,
a property should be considered as the definition of an attribute. An attribute must be associated
with a property, but a property may not have any attributes associated if none have been set.
A property is the definition of an attribute, it describes what the attribute is called, how it should
be type casted and other options such as the default value. These replace your typical
`add_column` methods found in relational database migrations.
Attributes with a property definition will have setter and getter methods defined for them. Any other attibute
can be set in the same way you'd update a Hash, this funcionality is inherited from CouchRest Documents.
In its simplest form, a property
will only create a getter and setter passing all attribute data directly to the database. Assuming the attribute
provided responds to `to_json`, there will not be any problems saving it, but when loading the
data back it will either be a string, number, array, or hash:
Here are a few examples of the way properties are used:

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.

TODO: Document properly!
This is a somewhat controvesial feature of CouchRest Model that some document database purists may fringe 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.

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:
CouchRestModel::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
CouchRest Model uses active_support for some of its internals. Ensure you have a stable active support gem installed
or at least 3.0.0.beta4.
None at the moment...
JSON gem versions 1.4.X are kown to cause problems with stack overflows and general badness. Version 1.2.4 appears to work fine.
## Ruby on Rails
CouchRest Model is compatible with rails and provides some ActiveRecord-like methods.

[http://github.com/hpoydar/couchrest-rails](http://github.com/hpoydar/couchrest-rails) is great

CouchRest Model and the original CouchRest ExtendedDocument do not share the same namespace,
as such you should not have any problems using them both at the same time. This might
help with migrations.

== Next Version
* Major enhancements
* Dirty Tracking via ActiveModel
* ActiveModel Attribute Methods support
* Support for configuration module and "model_type_key" option for overriding model's type key
* Added "mass_assign_any_attribute" configuration option to allow setting anything via the attribute= method.
* Minor enhancements
* Fixing find("") issue (thanks epochwolf)
* Altered protected attributes so that hash provided to #attributes= is not modified
* Altering typecasting for floats to better handle commas and points
* Fixing the lame pagination bug where database url (and pass!!) were included in view requests (Thanks James Hayton)
Notes:
* 2010-10-22 @samlown:
* ActiveModel Attribute support was added but has now been removed due to major performance issues.
Until these have been resolved (if possible?!) they should not be included. See the
'active_model_attrs' if you'd like to test.
