associated_object_keys()

The keys in the associated model’s table related to this association

[show source] 
     # File lib/sequel/model/associations.rb
1032 def associated_object_keys
1033   self[:keys]
1034 end
can_have_associated_objects?(obj)

one_to_many associations can only have associated objects if none of the :keys options have a nil value.

[show source] 
     # File lib/sequel/model/associations.rb
1038 def can_have_associated_objects?(obj)
1039   !self[:primary_keys].any?{|k| obj.get_column_value(k).nil?}
1040 end
cloneable?(ref)

one_to_many and one_to_one associations can be clones

[show source] 
     # File lib/sequel/model/associations.rb
1043 def cloneable?(ref)
1044   ref[:type] == :one_to_many || ref[:type] == :one_to_one
1045 end
default_key()

Default foreign key name symbol for key in associated table that points to current table’s primary key.

[show source] 
     # File lib/sequel/model/associations.rb
1049 def default_key
1050   :"#{underscore(demodulize(self[:model].name))}_id"

1058 end
handle_silent_modification_failure?()

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

[show source] 
     # File lib/sequel/model/associations.rb
1061 def handle_silent_modification_failure?
1062   self[:raise_on_save_failure] == false
1063 end
predicate_key()

The hash key to use for the eager loading predicate (left side of IN (1, 2, 3))

[show source] 
     # File lib/sequel/model/associations.rb
1066 def predicate_key
1067   cached_fetch(:predicate_key){qualify_assoc(self[:key])}
1068 end
primary_key()

The column in the current table that the key in the associated table references.

[show source] 
     # File lib/sequel/model/associations.rb
1072 def primary_key
1073   self[:primary_key]
1074 end
qualified_primary_key()

primary_key qualified by the current table

[show source] 
     # File lib/sequel/model/associations.rb
1077 def qualified_primary_key
1078   cached_fetch(:qualified_primary_key){qualify_cur(primary_key)}
1079 end
reciprocal_array?()

Whether the reciprocal of this association returns an array of objects instead of a single object, false for a one_to_many association.

[show source] 
     # File lib/sequel/model/associations.rb
1083 def reciprocal_array?
1084   false
1085 end
remove_before_destroy?()

Destroying one_to_many associated objects automatically deletes the foreign key.

[show source] 
     # File lib/sequel/model/associations.rb
1088 def remove_before_destroy?
1089   false
1090 end
remove_should_check_existing?()

The one_to_many association needs to check that an object to be removed already is associated.

[show source] 
     # File lib/sequel/model/associations.rb
1093 def remove_should_check_existing?
1094   true
1095 end
set_reciprocal_to_self?()

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