E   Edge

Select edges from your graph to begin traversal. 
E<Type>(edge_id)

​
Example 1: Selecting a follows edge by ID

QUERY GetFollowEdge (edge_id: ID) =>
    follow_edge <- E<Follows>(edge_id)
    RETURN follow_edge

QUERY CreateUser (name: String, age: U8, email: String) =>
    user <- AddN<User>({
        name: name,
        age: age,
        email: email
    })
    RETURN user

QUERY CreateRelationships (user1_id: ID, user2_id: ID) =>
    follows <- AddE<Follows>::From(user1_id)::To(user2_id)
    RETURN follows


from helix.client import Client

client = Client(local=True, port=6969)

alice = client.query("CreateUser", {
    "name": "Alice",
    "age": 25,
    "email": "alice@example.com",
})
alice_id = alice[0]["user"]["id"]

bob = client.query("CreateUser", {
    "name": "Bob",
    "age": 28,
    "email": "bob@example.com",
})
bob_id = bob[0]["user"]["id"]

follows = client.query("CreateRelationships", {
    "user1_id": alice_id,
    "user2_id": bob_id,
})
edge_id = follows[0]["follows"]["id"]

result = client.query("GetFollowEdge", {"edge_id": edge_id})
print(result)

​
Example 2: Selecting all follows edges

QUERY GetAllFollows () =>
    follows <- E<Follows>
    RETURN follows

from helix.client import Client

client = Client(local=True, port=6969)

result = client.query("GetAllFollows")
print(result)
