Pyrtable: Python framework for interfacing with Airtable
========================================================

Pyrtable is a Python 3 library to interface with `Airtable <https://airtable.com>`_\ 's REST API.

There are other Python projects to deal with Airtable. However, most of them basically offer a thin layer to ease authentication and filtering – at the end, the programmer still has to manually deal with JSON encoding/decoding, pagination, request rate limits, and so on.

Pyrtable is a high-level, ORM-like library that hides all these details. It performs automatic mapping between Airtable records and Python objects, allowing CRUD operations while aiming to be intuitive and fun. Programmers used to `Django <https://www.djangoproject.com>`_ will find many similarities and will (hopefully) be able to interface with Airtable bases in just a couple of minutes.

What does it look like?
-----------------------

Ok, let's have a taste of how one can define a class that maps onto records of a table:

.. code-block:: python

   import enum
   from pyrtable.record import BaseRecord
   from pyrtable.fields import StringField, DateField, SingleSelectionField, \
           SingleRecordLinkField, MultipleRecordLinkField

   class Role(enum.Enum):
       DEVELOPER = 'Developer'
       MANAGER = 'Manager'
       CEO = 'C.E.O.'

   class EmployeeRecord(BaseRecord):
       class Meta:
           # Open “Help > API documentation” in Airtable and search for a line
           # starting with “The ID of this base is XXX”.
           base_id = 'appABCDE12345'
           table_id = 'Employees'

       @classmethod
       def get_api_key(cls):
           # The API key can be generated in you Airtable Account page. 
           # DO NOT COMMIT THIS STRING!
           return 'keyABCDE12345'

       name = StringField('Name')
       birth_date = DateField('Birth date')
       office = SingleRecordLinkField('Office', linked_class='OfficeRecord')
       projects = MultipleRecordLinkField(
               'Allocated in projects', linked_class='ProjectRecord')
       role = SingleSelectionField('Role', choices=Role)

After that, common operations are pretty simple:

.. code-block:: python

   # Iterating over all records
   for employee in EmployeeRecord.objects.all():
       print("%s is currently working on %d project(s)" % (
           employee.name, len(employee.projects)))

   # Filtering
   for employee in EmployeeRecord.objects.filter(
           birth_date__gte=datetime.datetime(2001, 1, 1)):
       print("%s was born in this century!" % employee.name)

   # Creating, updating and deleting a record
   new_employee = EmployeeRecord(
       name='John Doe',
       birth_date=datetime.date(1980, 5, 10),
       role=Role.DEVELOPER)
   new_employee.save()

   new_employee.role = Role.MANAGER
   new_employee.save()

   new_employee.delete()

Notice that we don't deal with Airtable column or table names once record classes are defined.

Beyond the basics
-----------------

Keep in mind that Airtable is *not* a database system and is not really designed for tasks that need changing tons of data. In fact, only fetch (list) operations are batched – insert/update/delete operations are limited to a single record per request, and Airtable imposes a 5 requests per second limit even for paid accounts. You will need a full minute to update 300 records!

That said, Pyrtable will respect that limit. In fact, it will track dirty fields to avoid unnecessary server requests and will render ``.save()`` calls as no-ops for unchanged objects. That also works with multiple threads, so the following pattern can be used to update and/or create several records:

.. code-block:: python

   from concurrent.futures.thread import ThreadPoolExecutor

   all_records = list(EmployeeRecord.objects.all())

   # Do operations that change some records here
   # No need to keep track of which records were changed

   with ThreadPoolExecutor(max_workers=10) as executor:
       for record in all_records:
           executor.submit(record.save)

Or, if you want a really nice `tqdm <https://tqdm.github.io>`_ progress bar:

.. code-block:: python

   from tqdm import tqdm

   with ThreadPoolExecutor(max_workers=10) as executor:
       for _ in tqdm(executor.map(lambda record: record.save(), all_records),
                     total=len(all_records), dynamic_ncols=True, unit='',
                     desc='Updating Airtable records'):
           pass

Pyrtable also has some extra tools to cache data and read authentication keys from external JSON/YAML files check out the ``APIKeyFromSecretsFileMixin`` mixin class. Remember to never commit sensitive data to your repository, as Airtable authentication allows **full R/W access to all your bases** with a single API key!

Compatibility
-------------

Pyrtable is compatible with Python 3.7 and 3.8. Previous 3.x versions may or may not work. Python 2.x is not supported at all.
