This script generates QR codes from text content (e.g., URLs, product IDs) stored in a SeaTable column and saves the resulting images back into an image column. You can control whether existing QR codes should be overwritten.

from seatable_api import Base, context
import qrcode
from io import BytesIO

base = Base(context.api_token, context.server_url)
base.auth()

TABLE_NAME = "Table1"
TEXT_COLUMN = "URL"
IMAGE_COLUMN = "QR Code"
OVERWRITE = False

rows = base.list_rows(TABLE_NAME)
for row in rows:
    text = row.get(TEXT_COLUMN)
    existing = row.get(IMAGE_COLUMN)
    if not text or (existing and not OVERWRITE):
        continue

    qr = qrcode.QRCode(version=2, error_correction=qrcode.constants.ERROR_CORRECT_M, box_size=10, border=4)
    qr.add_data(text)
    qr.make(fit=True)
    img = qr.make_image(fill_color="black", back_color="white")

    buf = BytesIO()
    img.save(buf, format='PNG')
    buf.seek(0)

    info = base.upload_bytes_file(str(text) + '.png', buf.read(), file_type='image')
    base.update_row(TABLE_NAME, row['_id'], {IMAGE_COLUMN: [info.get('url')]})

print("QR codes generated.")

Set OVERWRITE = True if you want to regenerate existing QR codes. Adjust TEXT_COLUMN and IMAGE_COLUMN to match your column names.
