Question

我试图将图像上传到系统上的文件夹并为其提供唯一标识符。这样每个成员都可以拥有自己的个人资料图片。我在分配ID时遇到问题，并且不确定我是否正确地进行了此操作。另外，将图像放在SQLalchemy数据库中还是只放在文件夹中会更好吗？

@main.route("/upload", methods=['GET', 'POST'])
@login_required
def upload():
    if request.method == 'POST':
        file = request.files['file']
        if file and allowed_file(file.filename):
            filename = secure_filename(file.filename)
            rec = file(filename=filename, user=g.user.id)
            rec.store()
            file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
            return redirect(url_for('.home'))
    return """
    <!doctype html>
    <title>Upload new File</title>
    <h1>Upload new File</h1>
    <form action="" method=post enctype=multipart/form-data>
      <p><input type=file name=file>
         <input type=submit value=Upload>
    </form>
    <p>%s</p>
    """ % "<br>".join(os.listdir(app.config['UPLOAD_FOLDER'],))

我的错误：文件＆＃34; /home/ed/Development/Python/social/app/main/views.py"，第253行，上传 rec = file（filename = filename，user = g.user.id） TypeError：＆＃39; FileStorage＆＃39;对象不可调用

编写文件的正确方法是：

file = request.files['file']
if file and allowed_file(file.filename):
    filename = secure_filename(file.filename)
    file.save(os.path.join(app.config['UPLOAD_FOLDER'], actual_filename))

要使用此功能，您的配置中应该有UPLOAD_FOLDER。
