Question

我正在建立一个网站，人们应该可以添加带图片的小插件。所有图片都会转到同一目录。所以我需要重命名图片，这样就不会有任何重写或冲突。

当我向网站添加添加时，它会自动增加add_id。我想将此add_id用于图片名称。

def allowed_file(filename):
return '.' in filename and \
       filename.rsplit('.', 1)[1].lower() in ALLOWED_EXTENSIONS

@app.route('/aufgeben', methods=['GET', 'POST'])
def upload_file():
if request.method == 'POST':
    titel = request.form['titel']
    beschreibung = request.form['beschreibung']
    kategorie = request.form['kategorie']
    # check if the post request has the file part
    if 'file' not in request.files:
        flash('No file part')
        return redirect(request.url)
    file = request.files['file']
    # if user does not select file, browser also
    # submit a empty part without filename
    if file.filename == '':
        flash('No selected file')
        return redirect(request.url)
    if file and allowed_file(file.filename):
        filename = secure_filename(file.filename)
        file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
    # Anzeigeninhalt in DB eintragen
    cursor = g.con.cursor()
    cursor.execute('insert into anzeigen (titel, beschreibung, kategorie) values (%s, %s, %s)',
                   (titel, beschreibung, kategorie))
    g.con.commit()
    cursor.close()
    flash("Anzeige aufgegeben.")
return render_template('aufgeben.html',)

感谢您的帮助。也许有人有更好的想法如何解决这个问题？
