module Sequel::Plugins::TacticalEagerLoading::InstanceMethods
Attributes
retrieved_by[RW]
The dataset that retrieved this object, set if the object was reteived via Dataset#all
.
retrieved_with[RW]
All model objects retrieved with this object, set if the object was reteived via 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 139 def marshallable! 140 @retrieved_by = nil 141 @retrieved_with = nil 142 super 143 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 Dataset#all
, eagerly load the association for all model objects retrieved with the current object.
Calls superclass method
