Usage

Python client

Connect to a server

Connect to local host

from terminusdb_client import WOQLClient

client = WOQLClient("http://127.0.0.1:6363/")
client.connect()

Connect to TerminusX

check documentation for TerminusX about how to add the API token to the environment variable

from terminusdb_client import WOQLClient

team="MyTeam"
client = WOQLClient(f"https://dashboard.terminusdb.com/{team}/")
client.connect(team="MyTeam", use_token=True)

Create a database

client.create_database("MyDatabase")

Create a schema

from terminusdb_client.woqlschema import WOQLSchema, DocumentTemplate, RandomKey

my_schema = WOQLSchema()

class Pet(DocumentTemplate):
    _schema = my_schema
    name: str
    species: str
    age: int
    weight: float

my_schema.commit(client)

my_dog = Pet(name="Honda", species="Huskey", age=3, weight=21.1)
my_cat = Pet(name="Tiger", species="Bengal cat", age=5, weight=4.5)
client.insert_document([my_dog, my_cat])

Get back all documents

print(list(client.get_all_documents()))

[{'@id': 'Pet/b5edacf854e34fe79c228a91e2af45fb', '@type': 'Pet', 'age': 5, 'name': 'Tiger', 'species': 'Bengal cat', 'weight': 4.5}, {'@id': 'Pet/cdbe3f6d49394b38b952ae315309256d', '@type': 'Pet', 'age': 3, 'name': 'Honda', 'species': 'Huskey', 'weight': 21.1}]

Get a specific document

print(list(client.query_document({"@type":"Pet", "age":5})))

[{'@id': 'Pet/145eb73966d14a1394f7cd5576d7d0b8', '@type': 'Pet', 'age': 5, 'name': 'Tiger', 'species': 'Bengal cat', 'weight': 4.5}]

Delete a database

client.delete_database("MyDatabase")

Scaffolding CLI tool

$terminusdb importcsv grades.csv --na=error
0it [00:00, ?it/s]
Schema object Grades created with grades.csv inserted into database.
schema.py is updated with mydb schema.
1it [00:00,  1.00it/s]
Records in grades.csv inserted as type Grades into database with Lexical ids.

Get documents with query

terminusdb alldocs --type Grades -q grade="B-"
[{'@id': 'Grades/Android_Electric_087-65-4321_42.0_23.0_36.0_45.0_47.0_B-', '@type': 'Grades', 'final': 47.0, 'first_name': 'Electric', 'grade': 'B-', 'last_name': 'Android', 'ssn': '087-65-4321', 'test1': 42.0, 'test2': 23.0, 'test3': 36.0, 'test4': 45.0}, {'@id': 'Grades/Elephant_Ima_456-71-9012_45.0_1.0_78.0_88.0_77.0_B-', '@type': 'Grades', 'final': 77.0, 'first_name': 'Ima', 'grade': 'B-', 'last_name': 'Elephant', 'ssn': '456-71-9012', 'test1': 45.0, 'test2': 1.0, 'test3': 78.0, 'test4': 88.0}, {'@id': 'Grades/Franklin_Benny_234-56-2890_50.0_1.0_90.0_80.0_90.0_B-', '@type': 'Grades', 'final': 90.0, 'first_name': 'Benny', 'grade': 'B-', 'last_name': 'Franklin', 'ssn': '234-56-2890', 'test1': 50.0, 'test2': 1.0, 'test3': 90.0, 'test4': 80.0}]
