Flask before_request CannotSendRequest

[lthon09]

This error is often raised at times when I connect too fast and frequently, if I remove the before_request, the app works fine. I have already followed #270, it works fine if I comment out it. Any solutions?

[jnsougata]

what's the issue you are having? any tracebacks? some code of of before_request maybe... and most importantly does that takes a long time to finish that thing?

[lthon09]

no, it shouldnt take long, since its only a base check. the traceback is:

heres the code btw:

@_app.before_request # TODO: fix
def before_request():
    if app.get("maintenance")["value"]:
        return render_template("error.html", code=503, name="Undergoing Maintenance", message="We're on maintenance, come back later!"), 503

show the section where you call the deta code

[lthon09]

from modules.functions import get_env
from deta import Deta, _Base

def get_db(name : str) -> _Base:
    return Deta(get_env("db_key")).Base(name)

app = get_db("app")

users = get_db("users")

communities = get_db("communities")
posts = get_db("posts")

invite_codes = get_db("invite_codes")

action_logs = get_db("action_logs")
error_logs = get_db("error_logs")

here it is

[abdelhai]

you need to to call get_db inside a method/route/functions. otherwise you're defying the purpose of putting the initiation code in a function in the first place. example:

def my_route1():
    db1 = get_db("db1")

def my_route2():
    db1 = get_db("db1")

[lthon09]

ahh, ok. ty!
