kriss-associated_records_on_steroids

Plugin allowing to auto build and validate associated records and merge validation errors

== Examples

If you want automatically build specified associated recrods when new record is initialized you can use auto_build:

class Bar < ActiveRecord::Base belongs_to :foo end

class Foo < ActiveRecord::Base has_one :bar set_associated_records_to_auto_build :bar end

foo = Foo.new foo.bar # => #Bar:0x...

You can also validate associated record in easy way:

class Person < ActiveRecord::Base has_one :address validates_presence_of :name validates_associated_record :address delegate :street, :street=, :city, :city=, :state, :state=, :zip, :zip=, :to => :address end

class Address < ActiveRecord::Base validates_presence_of :street, :city, :state, :zip end

joe = Person.new joe.valid? # => false

joe.errors.on(:name) # => "can't be blank" joe.errors.on(:street) # => "can't be blank" joe.errors.on(:city) # => "can't be blank" joe.errors.on(:state) # => "can't be blank" joe.errors.on(:zip) # => "can't be blank"

And of course merging errors in not associated records:

class Person < ActiveRecord::Base validates_presence_of :name end

class Address < ActiveRecord::Base validates_presence_of :street, :city, :state, :zip end

joe = Person.new joe.valid? # => false address = Address.new address.valid? # => false

joe.errors.merge address.errors joe.errors.on(:name) # => "can't be blank" joe.errors.on(:street) # => "can't be blank" joe.errors.on(:city) # => "can't be blank" joe.errors.on(:state) # => "can't be blank" joe.errors.on(:zip) # => "can't be blank"

Enjoy!
