Django - statische Datei vom Server öffnen

Question

Ich habe sorgfältig documentation und mehrere Diskussionen im Zusammenhang mit dem Thema gelesen, kann aber immer noch nicht herausfinden, wo der Dollar aufhört. Ich möchte nur eine statische Datei in Django-Ansicht öffnen, einige Inhalte in sie schreiben und es

f = open('/static/egais_files/temp.txt', 'w') 

Methode zu speichern.

Meine Einstellungen:

"""

wie alles Sieht aus dem entspricht, was Dokumentation sagt. Hilf mir bitte ! Wo ist der Fehler ???

Answer 1

Um eine Datei zu öffnen, müssen Sie den Pfad der Datei an open übergeben. Sie übergeben die URL.

Es sollte so aussehen:

f = open(os.path.join(STATIC_ROOT,'egais_files/temp.txt'), 'w') 

Answer 2

In der Anfangscodeschnipsel Sie versuchen, eine Datei zu öffnen für in einem Unterverzeichnis aus dem Stammverzeichnis des Dateisystems zu schreiben. Sie müssen zwei Dinge sicherstellen. Der erste ist, dass Sie an den richtigen Ort schreiben. Wahrscheinlich müssen Sie die open-Anweisung in etwas mit einem absoluten Pfad ändern. Sie müssen außerdem sicherstellen, dass STATIC_ROOT/egais_files vorhanden ist, bevor Sie versuchen, die Datei zu erstellen. Für Python 3:

import os 
import os.path 
from django.conf import settings 

os.makedirs(os.path.join(settings.STATIC_ROOT,'egais_files'), exist_ok=True) 
f = open(os.path.join(settings.STATIC_ROOT,'egais_files','temp.txt'), 'w') 

Für Python 2:

import errno 
import os 
import os.path 
from django.conf import settings 

try: 
    os.makedirs(os.path.join(settings.STATIC_ROOT,'egais_files')) 
except OSError as xcpt: 
    if rcpt.errno == errno.EEXIST: 
     pass 
    else: 
     raise 

f = open(os.path.join(settings.STATIC_ROOT,'egais_files','temp.txt'), 'w')
