Update Context in Odoo Controller (request.env.context)

Question

I want to update request context,

request.env.context

At the moment I got this dictionary

{'lang': u'en_US', 'tz': False, 'uid': 21}

I wanna update lang key, and expected output of

request.env.context
{'lang': 'de_DE', 'tz': False, 'uid': 21}

Any idea how.

Answer 1

context = request.env.context.copy()
context.update({'lang': u'en_CA'})
request.env.context = context
