[request] need read only access to locked database

[thiswillbeyourgithub]

For reference : I'm using some more naive code :

from ankipandas import Collection, find_db
from shutil import copy
from pathlib import Path

original_db = find_db(user=profile_name)  # profile name supplied by user, None to use the first found
Path.mkdir(Path("cache"), exist_ok=True)  # create cache folder
temp_db = copy(original_db, f"cache/{deckname.replace(' ', '_')}")  # copying database to cache

col = Collection(path=temp_db)  # load ankipandas on the temporary directory

I'll use this in the future but I think it's still a very valuable feature to implement (for example with an argument like read_only=True)

Thanks a lot for being so reactive and helpful last time, it was very useful and I'm really appreciative of it.

Have a nice day!

Hi @thiswillbeyourgithub AnnA looks really cool!

How about a quick & dirty approach: You can probably simply copy the database file to a temporary directory and open that. This will basically give you read only access.
So something like this (not tested at all, from top of my head):

from pathlib import Path
import shutil
import tmpfile
import ankipandas as ap
db_path = ap.paths.find_db()
with tempfile.TemporaryDirectory() as tmpdirname:
    new_loc = Path(tempdirname) / db_path.name
    shutil.copy(db_path, new_loc)
    col = ap.Collection(new_loc)
    # do your stuff with the collection
# Copy will get deleted

Thanks a bunch, I thought about doing this but was not sure about how to create temporary file on all platforms.

Thanks a lot!

Sure, let me know if it works!

I'll try to, but I won't try it for quite some time. Don't wait for me :)
