Python flask session not getting stored in generator function
I am streaming output to the frontend using a generator in one of my flask routes and storing a value in a session variable like this:
@bp.route('/stream', methods=['GET', 'POST'])
@login_required
def stream():
def generate():
if request.method == "POST":
...
...
# trying to store a variable to use in another function
session['testing'] = "testing"
return Response(stream_with_context(generate()), mimetype='text/html')
I want to use this variable in another function like this:
@bp.route('/other_func', methods=['GET', 'POST'])
def other_func():
...
...
# trying to recieve it here
testing = session.get('testing')
print(testing) # this value is 'None'
Any variable I store in the generator function results to None
.
How can I get around this?
python-3.x session flask

Do you have secret key set in your flask app config ?

@DinkoPehar yes, it's in myinit.py
, this used to work before, after adding the generator function it stopped working, does the generator function somehow affect the session from being stored?

just before yoursession['testing'] = "testing"

Are you sure that generate function is executing that part in if statement ? Part request.method == 'POST' ?

@DinkoPehar I think that's what it is too, since the generator doesn't store the values and just iterates through it once, I believe my session is getting cleared out after the function is done. Trying to think of a way around this...
