Ok so i got the dgraph setup in an AWS test instance and ratel working fine connecting to it.
I wrote a simple python script and referred to the easiest example i can find :slight_smile:

from pydgraph.client import DgraphClient

g_Host = “13.250.197.28”

def AddData () :

dg_client = DgraphClient(g_Host, 8080)

response = dg_client.query("""mutation
    {
        set
        {
            <alice> <name> \"Alice\" .
            <greg> <name> \"Greg\" .
            <alice> <follows> <greg> .
        }
    }

    query
    {
        me(_xid_: alice)
        {
            follows
            {
                name _xid_
            }
        }
    }
    """)

print(response)

if name == “main” :
AddData()

—> But it gave an error and i do not know how to proceed from here

grpc.framework.interfaces.face.face.AbortionError: AbortionError(code=StatusCode.UNAVAILABLE, details="")

This example would not work as query and mutation need to be separate operations.

There is a pending PR for pydgraph at Add Dgraph v1 support and make the interface compatible with other clients by gpahal · Pull Request #21 · dgraph-io/pydgraph · GitHub which should be merged soon by @gpahal. The PR would also add examples.

The example are taken from :
https://docs.dgraph.io/v0.8.3/clients/

Update on docs would be useful for new comers.

Sure, once the PR is merged we will update the docs here as well.
