Store Image in Mysql datatabse using flask

问题

I'm trying to get this image from an html form and store it in the database. I'm not sure what I'm doing wrong. I want to be able to save the image in a blob field in the database. see my code.I'm using flask. The problem here is, I'm not able to store the image in the database.

   @app.route('/upload', methods=["POST"])
    def get_images():
        if request.method == "POST":
            file = request.files['imagename']
            file.save(file.filename)

            newFile = file.read()

            c, conn = connection()


            c.execute('''
                         INSERT INTO ImageTable( PHT_Image)
                         VALUES(%s)''',
                      [newFile1])
            conn.commit()

回答1:

I would strongly suggest saving file on disk and string path of that file into database. For eg:

APP_IMAGES = os.path.join(APP_ROOT, 'images/')

class RegistrationForm(Form):
    myImage = FileField('Choose Image file')

@app.route('/register/', methods=["GET","POST"])
def register_page():
    try:
        form = RegistrationForm(CombinedMultiDict((request.files, request.form)))
        filename = 'None'
        if request.method == "POST"):
            filename = secure_filename(form.avatar.data.filename)
            form.myImage.data.save(APP_IMAGES + filename)
            dbu = DatabaseUtility(db)
            dbu.RunCommand("INSERT INTO users (avatar) VALUES (%s)",thwart(filename)))
                dbu.Commit()
                dbu.Disconnect()
                flash("Done!")

    except Exception as e:
        return(str(e))
