v1.0 Pins API

This package currently only supports one operation with the official pins 1.0 API, Reading a pinned csv from RStudio Connect.

The legacy API for this package is still available. See below for more details.

Reading a pin on RStudio Connect

import the appropriate sub-module.

import pins.connect as pc

Then use the pin_read() function to read csv data pinned to Connect directly into a pandas dataframe.

pc.pin_read("<CONNECT_SERVER_URL>", "<CONNECT_API_KEY>", "<USER_NAME/PIN_NAME>")

Alternatively, you can return a dict of the pin metadata, by using the meta_only=True parameter.

For instance:

>>> pc.pin_read("https://connect.example.com.rstudio.com/rsc", 
... os.getenv("CONNECT_API_KEY"), 
... "mark.sellors/palmer_penguins",
... meta_only=True)
{'file': 'palmer_penguins.csv', 'file_size': '17299', 
'pin_hash': '809e9def88e78114', 'type': 'csv',
'title': "'palmer_penguins: a pinned 344 x 8 data frame'",
'description': '~', 'created': '20211029T120018Z', 'api_version': '1.0'}

Here's a complete example:

>>> import os
>>> import pins.connect as pc
>>> pc.pin_read("https://colorado.rstudio.com/rsc", 
... os.getenv("COLORADO_API_KEY"), "mark.sellors/palmer_penguins")

• pin_name (str): name of pin, only alphanumeric and underscores
• pretty_pin_name (str): display name of pin
• connect_server (str): RStudio Connect server address e.g. https://connect.example.com/
• api_key (str): API key of a user on RStudio Connect

Returns:

• Url of content

Get data from a python pin on RStudio Connect

pin_get_rsconnect(url, api_key):

Parameters:

• url (str) content solo URL on Connect (NOT dashboard URL)
• api_key (str): API key of a user on RStudio Connect

Returns:

• JSON version of pin

Try it out

import panads
import pins

mydata = {'col1': [1, 2], 'col2': [3, 4]}
df = pd.DataFrame(data=mydata)

# pin the data to connect
pin = pins.pin_rsconnect(
    data = df, 
    pin_name = "my_pin_7788", 
    pretty_pin_name = "Python Pin", 
    connect_server = connect_server, 
    api_key = api_key
)

# retrieve the pinned data
