Re: Flask 2 request POST nützen
Verfasst: Sonntag 23. Juni 2019, 17:18
Im Moment weiß ich gar nicht, was Du falsch machst, denn alles was zu tun ist, habe ich bereits gesagt. Ein komplett lauffähiges Beispiel, wäre jetzt ganz praktisch.
Wie kann ich jetzt dafür sorgen das auf last_selected nur dann zurückgeriffen wird wenn der andere Wert geändert wird? Also last_selected last soll nur benutzt werden wenn ich die mess_id ändere.
Code: Alles auswählen
@app.route('/dashboard/<id>', methods=['GET', 'POST'])
def dashboard(id):
mess_id = request.form.get('mess_id', 1)
last = request.form.get('last,', request.form.get('last_selected', 'tag'))
plots_date = []
if last == 'tag':
ask_length = 96
elif last == 'woche':
ask_length = 672
elif last == 'monat':
ask_length = 2880
else:
ask_length = 96
if 'date' in request.form:
ask_length = 96
start_date = request.form.get('start_date', "2018-01-01_00:00")
end_date = request.form.get('end_date', "2019-01-01_00:00")
plots_date = [
make_plot(mess_id, quantity, ask_length, start_date, end_date)
for quantity in PLOTS
]
plots = [
make_plot(mess_id, quantity, ask_length, None, None)
for quantity in PLOTS
]
