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.

[Source]

     # 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

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # 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))

[Source]

     # 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.

[Source]

     # File lib/sequel/model/associations.rb, line 933
933:         def primary_key
934:           self[:primary_key]
935:         end
qualified_key()

Alias for predicate_key

primary_key qualified by the current table

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # File lib/sequel/model/associations.rb, line 954
954:         def remove_should_check_existing?
955:           true
956:         end

One to many associations set the reciprocal to self when loading associated records.

[Source]

     # File lib/sequel/model/associations.rb, line 959
959:         def set_reciprocal_to_self?
960:           true
961:         end
