Data is already in binary in db. Making more test when pydal retrieve the blob data from the db is only getting just a part of the information.
When in print the rows after the select i get a small sample like this: images = cherry_db(cherry_db.image.node_id == i['node_id']).select(cherry_db.image.node_id, cherry_db.image.png) for m in images: print(m['png’]) b'<\xd1\x88\x1c4l\x04\x84\xce 0\x13\xc6\x01\r\xdd\xd0' Cheers -- Sent from Canary (https://canarymail.io) > On martes, may. 18, 2021 at 1:51 p. m., Kevin Keller <[email protected] > (mailto:[email protected])> wrote: > I think you have to convert the image file to binary data before saving tad > blob etc..? > > https://pynative.com/python-mysql-blob-insert-retrieve-file-image-as-a-blob-in-mysql/ > > > > On Tue, May 18, 2021, 19:04 Chris <[email protected] > (mailto:[email protected])> wrote: > > Hi, i’m trying to read images from a existing sqlite db.
