mitol-django-google-sheets-deferrals 2026.4.2

Library to handle Deferral requests using Google Sheets integrations in Django

mitol-django-google-sheets-deferrals

This is the Open Learning Django Google Sheets library for handling deferral requests over Google Sheets

Setup

Before you begin setting up this library make sure you set up mitol-django-google-sheets first. Follow the instructions here.

Once you have mitol-django-google-sheets installed, then:

pip install mitol-django-google-sheets-deferrals

In settings.py

INSTALLED_APPS = [
    ...
    "mitol.google_sheets_deferrals.apps.GoogleSheetsDeferralsApp",
]

MITOL_GOOGLE_SHEETS_DEFERRALS_PLUGINS = [
    "ecommerce.plugins.DeferralPlugin"
]

In ecommerce/plugins.py

from mitol.google_sheets_deferrals.hooks import hookimpl

class DeferralPlugin:
    @hookimpl
    def deferrals_process_request(deferral_request: DeferralRequestRow) -> DeferralResult:
        # TODO: look up the user/enrollment
        # TODO: unenroll user from and enroll to

Create your google sheets folder

The structure of the folder should look as the following:

1. Spreadsheet that contains sheets with 'Deferral Form Responses' and the 'Deferrals' sheets, that is being processed.
2. Request Form

Ask a developer for a template folder to copy this structure.

Add settings to your app

Set MITOL_GOOGLE_SHEETS_DEFERRALS_REQUEST_WORKSHEET_ID in your .env file. It is required.

Some settings have default values, which you might need to update, if your sheet is different.

Description of settings (in addition to the ones described in mitol-django-google-sheets):

• MITOL_GOOGLE_SHEETS_DEFERRALS_REQUEST_WORKSHEET_ID

  The IDs of the refund and deferral sheets in the change of enrollment spreadsheet. These can be found by opening the spreadsheet, selecting the "Refunds" or "Deferrals" worksheets, and copying down the gid value in the URL.

  Example: https://docs.google.com/spreadsheets/d/<MITOL_GOOGLE_SHEETS_ENROLLMENT_CHANGE_SHEET_ID>/edit#gid=<MITOL_GOOGLE_SHEETS_DEFERRALS_REQUEST_WORKSHEET_ID>

• MITOL_GOOGLE_SHEETS_DEFERRALS_PROCESSOR_COL

  The zero-based index of the deferral change sheet column that contains the user that processed the row

• MITOL_GOOGLE_SHEETS_DEFERRALS_COMPLETED_DATE_COL

  The zero-based index of the deferral change sheet column that contains the row completion date

• MITOL_GOOGLE_SHEETS_DEFERRALS_ERROR_COL

  The zero-based index of the deferral change sheet column that contains row processing error messages

• MITOL_GOOGLE_SHEETS_DEFERRALS_SKIP_ROW_COL

  The zero-based index of the deferral change sheet column that indicates whether the row should be skipped

• MITOL_GOOGLE_SHEETS_DEFERRALS_FIRST_ROW

  The first row (as it appears in the spreadsheet) of data that our scripts should consider processing in the deferral request spreadsheet

Usage

To processing your google sheet with deferral requests simply add:

deferral_request_handler = DeferralRequestHandler()
results = deferral_request_handler.process_sheet()

Here are two main ways that we are currently getting our Google Sheets Deferrals processed:

1. Run a management command. For example: ./manage.py process_deferral_requests -i "<spreadsheet id>"
2. Set up a scheduled celery task. For example:

from mitol.google_sheets_deferrals.api import DeferralRequestHandler
from main.celery import app

@app.task
def process_deferral_requests():
    """
    Task to process deferral requests from Google sheets
    """
    deferral_request_handler = DeferralRequestHandler()
    if not deferral_request_handler.is_configured():
        log.warning("MITOL_GOOGLE_SHEETS_* are not set")
        return
    deferral_request_handler.process_sheet()
