Cascade inserting for Notion Database Automation (as log)

Notion Cascade Insert

Installing

! pip install notion_cascade_insert

How to use

Building blocks

This package is built to emulate the Notion Automation function but with one to many relation. I built this to track the transactions (hence the log) that involves calculating in case where there is an big object that map to many other objects, like when you have a recipe and you want to get the ingredients, or when you have a lists of guests and you want to get their details… This helps you manage the ammoun of stuff that relate to that big object.

There are 4 of the pipelines:

1. TriggerDB: monitors a database for status changes
2. JunctionDB: looks up related items and amounts
3. LogDB: writes transaction logs
4. AutoLogger: orchestrates the flow

We can than use them to connect to Notion Webhook and create the functions that we want.

Example

Let’s say we’re building a Bakery Inventory management database, and we want our Production Plan database to automatically log the used ingredients in a recipe that we want to make. This is a one-to-many behavior, which Notion don’t support at the momment. For this, we would do something like:

from notion_cascade_insert.core import TriggerDB, JunctionDB, LogDB, AutoLogger
from notion_cascade_insert.webhook import NotionWebhook 
from fastapi import FastAPI, Request 
from notion_client import Client 
import os

notion = Client(auth=os.getenv("NOTION_TOKEN"))

trigger = TriggerDB(os.getenv("PRODUCTION_PLAN_DB_ID"), notion, "Status", "Recipes", "Batches to make")
junction = JunctionDB(os.getenv("RECIPE_INGREDIENTS_DB_ID"), notion, "Recipes", "Ingredient Inventory", "Amount per batch")
log = LogDB(os.getenv("INGREDIENT_TRANSACTION_DB"), notion, "Ingredient", "Amount", "Production Plan", "Reason")
db_logger = AutoLogger(trigger, junction, log, "In Process", -1)

This will create your Ingredient Logger! Then you can set up your server like so:

app = FastAPI()

@app.post("/webhook")
async def webhook(request: Request):
    hook = NotionWebhook(await request.json())
    if hook.parent_db_id == os.getenv("PRODUCTION_PLAN_DB_ID"):
        if hook.type == 'page.created': return {"result": db_logger.process(hook.entity_id)}
    return {"status": "received"}
