Disclaimer: This project is absolutely not meant to be a very pretty piece of code. This is only used for connecting ean code's to picnic id's. And it works. Also I'm in no way related to Picnic.
In this Repo you can find several scripts used by me to automate the Picnic - Grocy workflow. In my home a barcode scanner connected to a Raspberry Pi running the pi_canner.py scipt hangs above my main garbage bin. Everytime a product is diposed the barcode scanner removes a set amount from the Grocy stock. (My stock and products are mainly kept inside Grocy.)

Picnic sadly doesn't use ean code's in their app. So with this 'easy' tool I add all my items from my order in my basket and start scanning everything that is not yet known with a cheap barcode scanner. It's not ideal, but especialy the 'hunting mode' is very nice to use.
I'm using a MySQL database, containing 1 table named products that contains 6 columns:
| picnic_id | ean_code | description | quantity | price | jumbo_product |
|---|---|---|---|---|---|
| 10467828 | 8715817023754 | Aubergine | 1 stuk | 55 | NULL |
| 90006124 | 8718868261359 | Bio pastinaken | 400 gram | 139 | NULL |
The jumbo_product column is a bool that is only set to 1 when the product is a Jumbo product (I order from both Picnic and Jumbo, but Jumbo just uses the ean code so no need to store a diferent code.)
Create a venv using python3 -m venv ./venv
To activate the venv run source venv/bin/activate
Install the latests required packaged using pip install -r requirements.txt
rename .env.example to .env and fill in all the fields
Install virtualenv using pip install virtualenv
Create a venv using virtualenv --python C:\Path\To\Python\python.exe venv
To activate the venv run .\venv\Scripts\activate
Install the latests required packaged using pip install -r requirements.txt
rename .env.example to .env and fill in all the fields
When adding new packaged you should always update the requirements.txt file so the next developer can use this file to update their venv. You should use pip freeze > requirements.txt for convenience.
When you completed the above steps, just run the program using python index.py
This will fetch the Picnic API and save your current cart to a json file. This way you don't have to make a request to the Picnic API everytime, even when you stop the programm. When answering n it will assume the file is already present. So when running it for the first time: answer y
When enabled it will search on the Jumbo site for every product before asking you to select the product from your Picnic cart. WATCH OUT: When adding the product using the Jumbo product, you can't enter a Picnic id anymore. You should only use this when the product you're scanning is not for sale in the Picnic app
Only available when answering yes on the Jumbo site question This is used when wanting to quickly add procuts that are found on the Jumbo site. In my case I ran this on my PC and just scanned all Jumbo related prodcts I could find. DOES NOT ADD TO STOCK, ONLY USED TO CONVERT EAN TO NAME + INFO.
Only available when answering no on the Jumbo site question This is my ✨Favorite mode✨ This mode will just ask you to scan a certain product, so when you own a wireless scanner like I do, this is a amazing way of adding the products to the DB. It's like a egg hunt, but for ean codes 🥚
