TypeError: Unicode-objects and buffer interface
Hi all,
I read the warning that Python 3 support is higly experimental and that
feedback is welcome.
So here's a thing i came accross :-)
I'm writing a Flask application which used to work fine with python 3.4 and
these packages:
alembic==0.8.2itsdangerous==0.24
blinker==1.4 Jinja2==2.8
click==5.1Mako==1.0.2
configobj==5.0.6 Markdown==2.6.2

Flask==0.10.1 passlib==1.6.5
Flask-Admin==1.3.0pbr==1.8.0
flask-appconfig==0.11.0 psycopg2==2.6.1
Flask-Bootstrap==3.3.5.6 py-bcrypt==0.4
Flask-Login==0.2.11 python-editor==0.4
Flask-Mail==0.9.1 six==1.9.0

Flask-WTF==0.12 virtualenv==1.11.6
inflect==0.2.5Werkzeug==0.10.4
wheel==0.24.0
WTForms==2.0.2
I use a little start-script for developing which looks like this:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from myapp import app
app.debug = True
print(__name__)
if __name__ == '__main__':
app.run(host='0.0.0.0',debug=True)
Everything works fine.
Now i wanted to use more up-to-date packages (but Python is still version
3.4):

Re: TypeError: Unicode-objects and buffer interface
Hi,
This was a regression in the newly released Werkzeug 0.11 for Python 3
users. I just pushed out a new version 0.11.1 that fixes this. Note
that host needs to be a string and not bytes on Python 3 so you should
remove the `b` prefix.
Regards,
Armin
