module Sequel::Plugins::TacticalEagerLoading::InstanceMethods

Attributes

retrieved_by[RW]

The dataset that retrieved this object, set if the object was reteived via Sequel::Dataset#all.

retrieved_with[RW]

All model objects retrieved with this object, set if the object was reteived via Sequel::Dataset#all.

Public Instance Methods

marshallable!() click to toggle source

Remove #retrieved_by and #retrieved_with when marshalling. #retrieved_by contains unmarshallable objects, and #retrieved_with can be very large and is not helpful without retrieved_by.

Calls superclass method
# File lib/sequel/plugins/tactical_eager_loading.rb, line 83
def marshallable!
  @retrieved_by = nil
  @retrieved_with = nil

end

Private Instance Methods

load_associated_objects(opts, dynamic_opts=OPTS, &block) click to toggle source

If there the association is not in the associations cache and the object was reteived via Sequel::Dataset#all, eagerly load the association for all model objects retrieved with the current object.

Calls superclass method
# File lib/sequel/plugins/tactical_eager_loading.rb, line 94

      # This can happen if class table inheritance is used and the association
      # is only defined in a subclass.  This particular instance can use the
      # association, but it can't be eagerly loaded as the parent class doesn't
      # have access to the association, and that's the class doing the eager loading.
