failed to relate: Unable to save document error

[TobiEiss]

I cant persist a new entry into a edge-collection.
The result of a debug-session: we get 404 from http-rest-arango-endpoint.

I get the same error with the "relate-example" (README).

Hello @TobiEiss , I will check this. Thanks fro report. Which Arangodb version are you using? and wich aranGO version?

[TobiEiss]

@diegogub arango version 3.1.1

And i found the Problem:

• The request-link is wrong (was right in an older version).

A little (dirty) workaround:
instead of (README-example):

// Relate documents
s.DB("test").Col("ed").Relate(d1.Id,d2.Id,map[string]interface{}{ "is" : "friend" })

use:

edge := map[string]interface{}{}
edge["is"] = d1.ID
edge["friend"] = d2.ID
err := s.DB("test").Col("ed").Save(edge)

AND change in collection.go (line 135)
if col.Type == 2 || col.Type == 3 {

(newest arangodb version, with master and v2 branch of aranGO)

[TobiEiss]

Ah, okay. My workaround is for master-branch

[stefanwuthrich]

for me it did not work on master and v2 branch
