The keys in the associated model‘s table related to this association
# File lib/sequel/model/associations.rb, line 973 973: def associated_object_keys 974: self[:keys] 975: end
one_to_many associations can only have associated objects if none of the :keys options have a nil value.

one_to_many and one_to_one associations can be clones
# File lib/sequel/model/associations.rb, line 984 984: def cloneable?(ref) 985: ref[:type] == :one_to_many || ref[:type] == :one_to_one 986: end
Default foreign key name symbol for key in associated table that points to current table‘s primary key.
# File lib/sequel/model/associations.rb, line 990 990: def default_key 991: 992: "#{underscore(demodulize(self[:model].name))}_id" 993: end

Handle silent failure of add/remove methods if raise_on_save_failure is false.

The hash key to use for the eager loading predicate (left side of IN (1, 2, 3))
# File lib/sequel/model/associations.rb, line 1007 1007: def predicate_key 1008: cached_fetch(:predicate_key){qualify_assoc(self[:key])} 1009: end
The column in the current table that the key in the associated table references.
# File lib/sequel/model/associations.rb, line 1013 1013: def primary_key 1014: self[:primary_key] 1015: end
primary_key qualified by the current table

Whether the reciprocal of this association returns an array of objects instead of a single object, false for a one_to_many association.
# File lib/sequel/model/associations.rb, line 1024 1024: def reciprocal_array? 1025: false 1026: end
Destroying one_to_many associated objects automatically deletes the foreign key.
# File lib/sequel/model/associations.rb, line 1029 1029: def remove_before_destroy? 1030: false 1031: end
The one_to_many association needs to check that an object to be removed already is associated.
# File lib/sequel/model/associations.rb, line 1034 1034: def remove_should_check_existing? 1035: true 1036: end
