QueryFactory¶
- This class builds and executes a Cypher query, using information from the graph objects to determine
- whether they need to be created simultaneously. It keeps the rel instance from being responsible for inspecting the nodes or talking with Shared::QueryFactory.
Constants¶
- NODE_SYMBOLS
Methods¶
- #build!
TODO: This feels like it should also wrap the rel, but that is handled in Neo4j::ActiveRel::Persistence at the moment. Builds and executes the query using the objects giving during init. It holds the process:
- Execute node callbacks if needed
- Create and execute the query
- Mix the query response into the unpersisted objects given during init
def build! node_before_callbacks! do res = query_factory(rel, rel_id, iterative_query).query.unwrapped.return(*unpersisted_return_ids).first node_symbols.each { |n| wrap!(send(n), res, n) } @unwrapped_rel = res.send(rel_id) end end
- #from_node
Returns the value of attribute from_node
def from_node @from_node end
#initialize
def initialize(from_node, to_node, rel) @from_node = from_node @to_node = to_node @rel = rel end
- #rel
Returns the value of attribute rel
def rel @rel end
- #to_node
Returns the value of attribute to_node
def to_node @to_node end
- #unwrapped_rel
Returns the value of attribute unwrapped_rel
def unwrapped_rel @unwrapped_rel end
