Makes sure a class gets all the methods when it includes Resource
Note that including this module into an anonymous class will leave the model descendant tracking mechanism with no possibility to reliably track the anonymous model across code reloads. This means that {DataMapper::DescendantSet} will currently leak memory in scenarios where anonymous models are reloaded multiple times (as is the case in dm-rails development mode for example).

Public Instance Methods
Compares two Resources to allow them to be sorted
@param [Resource] other
The other Resource to compare with
@return [Integer]
Return 0 if Resources should be sorted as the same, -1 if the other Resource should be after self, and 1 if the other Resource should be before self
@api public
# File lib/dm-core/resource.rb, line 505 def <=>(other) model = self.model unless other.kind_of?(model.base_model) raise ArgumentError, "Cannot compare a #{other.class} instance with a #{model} instance" end model.default_order(repository_name).each do |direction| cmp = direction.get(self) <=> direction.get(other) return cmp if cmp.nonzero? end 0 end
Compares another Resource for equivalency
Resource is equivalent to other
if
they are the same object (identical object_id) or all of their attribute
are equivalent
@param [Resource] other
the other Resource to compare with
@return [Boolean]
true if they are equivalent, false if not
@api public
# File lib/dm-core/resource.rb, line 488 def ==(other) return true if equal?(other) return false unless other.kind_of?(Resource) && model.base_model.equal?(other.model.base_model) cmp?(other, :==) end
Checks if an attribute has unsaved changes
@param [Symbol] name
name of attribute to check for unsaved changes
@return [Boolean]
true if attribute has unsaved changes
@api semipublic
# File lib/dm-core/resource.rb, line 600 def attribute_dirty?(name) dirty_attributes.key?(properties[name]) end
Returns the value of the attribute.
Do not read from instance variables directly, but use this method. This method handles lazy loading the attribute and returning of defaults if nessesary.
@example
class Foo include DataMapper::Resource property :first_name, String property :last_name, String def full_name "#{attribute_get(:first_name)} #{attribute_get(:last_name)}" end # using the shorter syntax def name_for_address_book "#{last_name}, #{first_name}" end end
@param [Symbol] name

@return [Object]
the value stored at that given attribute (nil if none, and default if necessary)
@api public
# File lib/dm-core/resource.rb, line 239 def attribute_get(name) property = properties[name] persistence_state.get(property) if property end
Checks if an attribute has been loaded from the repository
@example
class Foo include DataMapper::Resource property :name, String property :description, Text, :lazy => false end Foo.new.attribute_loaded?(:description) #=> false

@return [Boolean]
true if ivar +name+ has been loaded
@api private
# File lib/dm-core/resource.rb, line 587 def attribute_loaded?(name) properties[name].loaded?(self) end
Sets the value of the attribute and marks the attribute as dirty if it has been changed so that it may be saved. Do not set from instance variables directly, but use this method. This method handles the lazy loading the property and returning of defaults if nessesary.
@example
class Foo include DataMapper::Resource property :first_name, String property :last_name, String def full_name(name) name = name.split(' ') attribute_set(:first_name, name[0]) attribute_set(:last_name, name[1]) end # using the shorter syntax def name_from_address_book(name) name = name.split(', ') first_name = name[1] last_name = name[0] end end

Reloads association and all child association
This is accomplished by resetting the Resource key to it's original value, and then removing all the ivars for properties and relationships. On the next access of those ivars, the resource will eager load what it needs. While this is more of a lazy reload, it should result in more consistent behavior since no cached results will remain from the initial load.
