Answer 1

that's my solution, it can work in my website:

@main.route('/upload', methods=['GET', 'POST'])
def upload_avatar():
    if request.method == 'POST':
        file = request.files['file']
        if file and allowed_file(file.filename):
            current_user.avatar_local = file.read()
            db.session.add(current_user)
            db.session.commit()
            return redirect(url_for('main.user_page', username=current_user.username))
    return render_template('upload_avatar.html', user=current_user)

using Flask,Flask-Alchemy to handle database.

{% block edit_avatar  %}
    

      

         
    
{% endblock %}

that's html file.you can embed it in you html.
