在ArangoDB中的两个文档之间添加边

Question

It should be easy operation but I can't find how to achieve this. I have two documents from different collections and now I want to link them using new Edge from existing collection. I'm trying to use edge-collection.save function like this: edge-collection.save(FOR s IN Sy FILTER s._key=403560128,FOR i IN Im FILTER i._key=353031872, points) but it doesn't work. How can I do this?

Answer 1

edge-collection.save() does not expect AQL statements as you are trying to insert. It is expecting raw _id attributes for from and to and as a thir parameter a JSON Object containing additional data for the edge. To store the edge described in your example you can execute the following command:

edge-collection.save("Sy/403560128", "Im/353031872", points); ^^^^^ ^^^^^ ^^^^ sourceId targetId JSON
