The keys in the associated model‘s table related to this association
# File lib/sequel/model/associations.rb, line 900 900: def associated_object_keys 901: self[:keys] 902: end
one_to_many associations can only have associated objects if none of the :keys options have a nil value.
# File lib/sequel/model/associations.rb, line 906 906: def can_have_associated_objects?(obj) 907: !self[:primary_keys].any?{|k| obj.get_column_value(k).nil?} 908: end
one_to_many and one_to_one associations can be clones
# File lib/sequel/model/associations.rb, line 911 911: def cloneable?(ref) 912: ref[:type] == :one_to_many || ref[:type] == :one_to_one 913: 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 917 917: def default_key 918: 919: "#{underscore(demodulize(self[:model].name))}_id" 920: end
Handle silent failure of add/remove methods if raise_on_save_failure is false.
# File lib/sequel/model/associations.rb, line 922 922: def handle_silent_modification_failure? 923: self[:raise_on_save_failure] == false 924: end
The hash key to use for the eager loading predicate (left side of IN (1, 2, 3))
# File lib/sequel/model/associations.rb, line 927 927: def predicate_key 928: cached_fetch(:predicate_key){qualify_assoc(self[:key])} 929: end
The column in the current table that the key in the associated table references.
# File lib/sequel/model/associations.rb, line 933 933: def primary_key 934: self[:primary_key] 935: end
primary_key qualified by the current table
# File lib/sequel/model/associations.rb, line 938 938: def qualified_primary_key 939: cached_fetch(:qualified_primary_key){qualify_cur(primary_key)} 940: end
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 944 944: def reciprocal_array? 945: false 946: end
Destroying one_to_many associated objects automatically deletes the foreign key.
# File lib/sequel/model/associations.rb, line 949 949: def remove_before_destroy? 950: false 951: 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 954 954: def remove_should_check_existing? 955: true 956: end
