## Assocations
|

Two types at the moment:
|

|
||||
belongs_to :person

collection_of :tags

## 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.
|
||||
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'
|
||||
|
||||
|
||||
|
||||
## Notable Issues
|
||||
|
||||
CouchRest Model uses active_support for some of its internals. Ensure you have a stable active support gem installed
