问题 As a proof-of-concept I need to create a HTTP server which on GET request should start continuous stream of non-encoded/non-compressed audio data - WAV, PCM16. Let's assume the audio data are chunks of 4096 randomly generated mono audio samples @44.1kHz sampling rate. What should I put in the HTTP response header in order to browser on the other end start a player in its UI for the user to listen in realtime? I was reading about "Transfer-Encoding: chunked", "multipart", mimetype="audio/xwav"

问题 I am using WTForms in conjunction with Flask and I would like to integrate the Bootstrap Form Validation for errors in my form.

问题 I'm developing a web app using Flask, SQLAlchemy and WTForms. I would like to get my choices in a SelectField from a query through my DB. With more details. my_query = my_table.query.with_entities(My_Entities).all() Result [(u'1',), (u'2',), (u'3',)] My class class MyForm(Form): My_Var = SelectField(choices=RIGHT_HERE) Is there any way ? 回答1: In this situation what you can do is use the extensions that are in WTForms. What you do is import the QuerySelectField that you need: from wtforms.ext
