Instance Method Details

#read_attribute_for_validation(attr) ⇒ Object

Overrides the default ActiveModel behaviour since we need to handle validations of relations slightly different than just calling the getter.

Examples:

Read the value.

person.read_attribute_for_validation(:addresses)

Parameters:

  • attr (Symbol) —

    The name of the field or relation.

Returns:

  • (Object) —

    The value of the field or the relation.

Since:

  • 2.0.0.rc.1

def read_attribute_for_validation(attr)
  if relations[attr.to_s]
    send(attr, false, :eager => true)
  else
    send(attr)
  end
end

#valid?(context = nil) ⇒ true, false

Determine if the document is valid.

Examples:

Is the document valid?

person.valid?

Is the document valid in a context?

person.valid?(:create)

Parameters:

  • context (Symbol) (defaults to: nil) —

    The optional validation context.

Returns:

  • (true, false) —

    True if valid, false if not.

Since:

  • 2.0.0.rc.6

def valid?(context = nil)
  super context ? context : (new? ? :create : :update)
end

#validated? ⇒ true, false

Used to prevent infinite loops in associated validations.

Examples:

Is the document validated?

document.validated?

Returns:

  • (true, false) —

    Has the document already been validated?

Since:

  • 2.0.0.rc.2
