Edges API
CRUD operations
The API for documents and edges have been unified in ArangoDB 3.0. The CRUD operations for documents and edges are now handled by the same endpoint at
/_api/document. For CRUD operations there is no distinction anymore between documents and edges API-wise.That means CRUD operations concerning edges need to be sent to the HTTP endpoint
/_api/documentinstead of/_api/edge. Sending requests to/_api/edgewill result in an HTTP 404 error in 3.0. The following methods are available at/_api/documentfor documents and edge:
- HTTP POST: insert new document or edge
- HTTP GET: fetch an existing document or edge
- HTTP PUT: replace an existing document or edge
- HTTP PATCH: partially update an existing document or edge
- HTTP DELETE: remove an existing document or edge
When completely replacing an edge via HTTP PUT please note that the replacing edge data now needs to contain the
_fromand_toattributes for the edge. Previous versions of ArangoDB did not require sending_fromand_towhen replacing edges, as_fromand_tovalues were immutable for existing edges.The _from and _to attributes of edges now also need to be present inside the edges objects sent to the server:
curl -X POST \ --data '{"value":1,"_from":"myVertexCollection/1","_to":"myVertexCollection/2"}' \ "http://127.0.0.1:8529/_api/document?collection=myEdgeCollection"Previous versions of ArangoDB required the _from and _to attributes of edges be sent separately in URL parameter from and to:
curl -X POST \ --data '{"value":1}' \ "http://127.0.0.1:8529/_api/edge?collection=e&from=myVertexCollection/1&to=myVertexCollection/2"

I am using node js server side. | I want to store value in edgeCollection whenever We are storing any value in an particular collection.
It was working in AurangoDB 2.8 version but getting issue in Arango3.2. Error are as below.
{ error: true, code: 404, errorNum: 404, errorMessage: 'unknown path \'/_api/edge?collection=offerCollection&from=userCollection%2FnhRJ2VYARet5AepC4vOMuO5Nm4F1BG&to=serviceCollection%2F4863\'' }, rawBody: '{"error":true,"code":404,"errorNum":404,"errorMessage":"unknown path \'/_api/edge?collection=offerCollection&from=userCollection%2FnhRJ2VYARet5AepC4vOMuO5Nm4F1BG&to=serviceCollection%2F4863\'"}' } }
