can_have_associated_objects?(obj) click to toggle source

many_to_pg_array associations can have associated objects as long as they have a primary key.

# File lib/sequel/plugins/pg_array_associations.rb, line 96
def can_have_associated_objects?(obj)

# File lib/sequel/plugins/pg_array_associations.rb, line 102
def default_key
  :"#{underscore(demodulize(self[:model].name))}_ids"
end

def eager_graph_limit_strategy(_)
  :ruby if self[:limit]
end
eager_limit_strategy() click to toggle source

predicate_key() click to toggle source

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

# File lib/sequel/plugins/pg_array_associations.rb, line 129
def predicate_key
  cached_fetch(:predicate_key){qualify_assoc(self[:key_column])}
end
primary_key() click to toggle source

# File lib/sequel/plugins/pg_array_associations.rb, line 135
def primary_key
