Usage examples

Fetch a groq query

import urequests
from usanity import query_request

sensor_id = "temperature-xyz"

# Fetch the sensor from the dataset using groq (https://groq.dev/)
url, headers = query_request(
    "*[_type == 'sensor' && _id == $id]",
    variables={"id": sensor_id},
    # Get your own project and dataset at https://www.sanity.io/get-started/create-project
    project_id="<your project id>",
    dataset="<your dataset>",
    # API version to use - see https://www.sanity.io/docs/api-versioning for more info
    api_version="2023-03-10",
    # A token with read access (optional for public datasets)
    token="<token>",
    # use the API CDN (https://www.sanity.io/docs/api-cdn)
    use_cdn=True
)
# Use urequests to perform the actual http request for us
res = urequests.get(url, headers=headers)
sensors = res.json['result']

print(sensors)

Mutate a document

import urequests
from usanity import mutate_request
from usanity.mutations import (
    create_if_not_exists,
    patch,
    patch_set,
    set_if_missing,
    unset,
    insert,
)

sensor_document_id = 'temperature-xyz'

# Get the sensor value (e.g. read from PIN)
sensor_value = read_sensor()

mutations = [
    create_if_not_exists({
        "_id": sensor_document_id,
        "_type": "sensor"
    }),
    # set the current value
    patch(sensor_document_id, patch_set("value", sensor_value)),
    # make sure we have a history array
    patch(sensor_document_id, set_if_missing("history", [])),
    # prepend the sensor value to the history array
    patch(sensor_document_id, insert("history", "before", 0, [
        {"timestamp": ntptime.time(), "value": sensor_value}
    ])),
]

url, headers, body = mutate_request(
    mutations,
    # Get your own project and dataset at https://www.sanity.io/get-started/create-project
    project_id="<your project id>",
    dataset="<your dataset>",
    # API version to use - see https://www.sanity.io/docs/api-versioning for more info
    api_version="2023-03-10",
    # Required for writes - create your own write-token at https://www.sanity.io/manage/project/<your-projectid>/api
    token="<token>",
)

# Use urequests to perform the actual http request for us
res = urequests.post(url, json=body, headers=headers)

# Print the response
print(res.json)
