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.

[Source]

     # File lib/sequel/model/associations.rb, line 979
979:         def can_have_associated_objects?(obj)
980:           !self[:primary_keys].any?{|k| obj.get_column_value(k).nil?}
981:         end

one_to_many and one_to_one associations can be clones

[Source]

     # 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

     # File lib/sequel/model/associations.rb, line 997
997:         def finalize_settings
998:           FINALIZE_SETTINGS
999:         end

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

      # File lib/sequel/model/associations.rb, line 1002
1002:         def handle_silent_modification_failure?
1003:           self[:raise_on_save_failure] == false
1004:         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 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.

[Source]

      # File lib/sequel/model/associations.rb, line 1013
1013:         def primary_key
1014:           self[:primary_key]
1015:         end
qualified_key()

Alias for predicate_key

primary_key qualified by the current table

[Source]

      # File lib/sequel/model/associations.rb, line 1018
1018:         def qualified_primary_key
1019:           cached_fetch(:qualified_primary_key){qualify_cur(primary_key)}
1020:         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 1024
1024:         def reciprocal_array?
1025:           false
1026:         end

Destroying one_to_many associated objects automatically deletes the foreign key.

[Source]

      # 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.

[Source]

      # File lib/sequel/model/associations.rb, line 1034
1034:         def remove_should_check_existing?
1035:           true
1036:         end

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

[Source]

      # File lib/sequel/model/associations.rb, line 1039
1039:         def set_reciprocal_to_self?
1040:           true
1041:         end
