I need to delete all relationships between all nodes. Is there any way to delete all relationships in the neo4j graph? Note that I am using ruby bindings - the neography gem. There is no info about that in the wiki of the gem. I've also tried to find a way to do it in the neo4j documentation without any result.
我需要删除所有节点之间的所有关系。有没有办法删除neo4j图中的所有关系？请注意，我正在使用ruby绑定 - neography gem。在gem的wiki中没有关于它的信息。我也试图在neo4j文档中找到一种方法，没有任何结果。
Neo4j version is 1.7.2.

in cypher:
在密码中：
deleting all relationships:
删除所有关系：
start r=relationship(*) delete r;
creating all relationships between all nodes, i'd assume:
创建所有节点之间的所有关系，我假设：
start n=node(*),m=node(*) create unique n-[r:RELTYPE]-m;
but you rather dont want to have too many vertices, since it collapse on low memory (at least in my case i got 1mil vertices and 1gb ram)
但你宁愿不要有太多顶点，因为它在低内存上崩溃（至少在我的情况下我有1mil顶点和1gb ram）
