ceramicsdk 0.1.3

This Ceramic client implements the payload building, encoding, and signing needed to interact with the Ceramic Network. It currently supports ModelInstanceDocument and OrbisDB.

Ceramic and OrbisDB Python Client

These Orbis and Ceramic clients implements the payload building, encoding, and signing needed to interact with the Ceramic Network. It currently supports ModelInstanceDocument.

Features

• Implements payload building, encoding, and signing for Ceramic interactions
• Currently supports ModelInstanceDocument

Install the library using pip

pip3 install ceramicsdk

Instantiating a Client

You can use the Orbis Studio or run a local or self-hosted OrbisDB Instance to locate and configure your context ID, environment ID, and node endpoints (used below).

This README will utilize this data model as the input example.

First, generate a Decentralized Identifier (DID) using a DID library.

from ceramicsdk import OrbisDB

# using an existing data model example
table = "kjzl6hvfrbw6c6adsnzvbyr6itmf0igfy25xu0mqzei2pe2xw1hlusqyuknb9ky"

# using an existing context id
context = "<your-context-here>"

# dedicated orbis and ceramic endpoints 
o_endpoint = "<your-endpoint-here>"
c_endpoint = "<your-endpoint-here>"

# create a private key
privkey = os.urandom(32).hex()

# creating a client
db = OrbisDB(c_endpoint, o_endpoint, context, table, privkey)

Creating a Row

# input content must conform to data model used
doc = db.add_row({
    page: "/home",
    address: "0x8071f6F971B438f7c0EA72C950430EE7655faBCe",
    customer_user_id: 3,
    timestamp: "2024-09-25T15:06:14.957719+00:00"
})

Reading Data

env_id = "<your-env-id-here>"

# select rows without any filters
docs = orbis.read(env_id)

# using a defined query
q = 'SELECT * FROM kjzl6hvfrbw6c6adsnzvbyr6itmf0igfy25xu0mqzei2pe2xw1hlusqyuknb9ky as table WHERE table.customer_user_id = 3'
queried_rows = db.query(env_id, q)

Updating Data

# add a filter to select specific row
filters={"customer_user_id": 3}

# new content to replace the old
new_content={"customer_user_id": 2}

updated_rows = db.update_rows(env_id, filters, new_content)
