Pypgrest
A Python client for interacting with PostgREST APIs.
Installation
$ pip install pypgrest
Quick start
>>> from pypgrest import Postgrest
>>> client = Postgrest("https://api.tacos.com", token="secretsalsa")
# See postgrest docs for supported query params
>>> params = {
"select" : "name,tortilla,cost",
"tortilla" : "is.corn",
"limit" : 100,
"order": "name"
}
# Supported methods are select, insert, update, upsert, and delete
>>> client.select(resource="menu", params=params, pagination=True, headers=None)
# [{ "name" : "al pastor", "tortilla" : "corn", "cost" : "2.01" }, ... ]
>>> payload = [{ "id" : 23, "cost" : "2.25" }, { "id" : 26, "cost" : "1.25" }]
>>> pgrest.upsert(payload)
# [{ "id" : 23, "cost" : "2.25", "name" : "al pastor", ... }, ... ]
# You can inspect the response object at `self.res`:
>>> client.res.status_code
# 201Headers
The client is initialized with Content-Type=application/json and (if you supply a token) Authorization headers. You can supply additional headers on construction, or per request.
>>> client = Postgrest(
"https://api.tacos.com",
token="secretsalsa",
headers={"Prefer": "return=representation"}
)
>>> client.headers
# {"Content-Type": 'application/json', 'Authorization': 'Bearer secretsalsa', 'Prefer': 'return=representation'}
>>> client.insert(
resource="menu",
data={"id": 5, "name": "barbacoa"},
headers={"Prefer": "return=headers-only"}
)Limits and pagination
By default, the client will paginate requests until all records have been retrieved. You can supply a limit param to limit the number of results returned by select.
You can disable pagination with pagination=False, in which case the record limit will be capped by your API's max-rows setting.
Development
We use Github Actions to publish to PyPI. The workflows are defined in .github/workflows.
Any commit/merge to the dev branch will trigger a PyPI publication to the knackpy-dev package. Any release on the master branch will trigger publication to the knackpy package on PyPI. Note that PyPI publications will fail if don’t bump the version number in setup.py.
