Using dcc.Interval trigger invocation of auth_function on set interval #153
Description
I have a dcc.Interval defined in one of my pages and BasicAuth for authentication with an auth_func. After I login, the auth_func is invoked on each interval. Is this behavior expected? If it is, what can I check in the auth_func to skip my credentials checking (avoid db/api call) when it is called in the interval?
auth_func
def authorization_function(username, password):
print("Calling Auth: {}".format(datetime.now()))
if (username == "hello") and (password == "world"):
return True
else:
return False

from dash import html, dcc, register_page, callback, Output, Input
from datetime import datetime
register_page(__name__, path_template="/user/<user_id>/public")
def layout(user_id: str):
return [
html.H1(f"User {user_id} (authenticated only)"),
html.Div("Members-only information"),
html.Div(id="interval-holder"),
dcc.Interval(id="interval-component", interval=3000),
]
@callback(
Output("interval-holder", "children"),
Input("interval-component", "n_intervals"),
)
def interval_update(n_intervals):
return "Now is {}".format(datetime.now())
