How to get 'requests' object in custom function in django

Question

I have created one library file where I have created one function suppose :

def myfunc(param1):
    ----
    --- do something
    ----

Now If I require requests object (to get details of user or something like that), How can I get requests object without passing parameter in my function.

Note : As of now I am adding requests in my parameters (shown as below) but is there any other method as If I am calling this function to any other function I might not have requests object.

def myfunc(requests,param1):
    ----
    --- do something
    ----

Answer 1

I have get solution that I can install a middleware like TLSRequestMiddleware where we need to install :

pip install django-tls

and then,

# settings.py
MIDDLEWARE_CLASSES = (
    'tls.TLSRequestMiddleware',
    ...
)

In case in django version 1.10, you update package as :

try:
    from threading import local
except ImportError:
    from django.utils._threading_local import local

_thread_locals = local()

def get_current_request():
    return getattr(_thread_locals, 'request', None)

def get_current_user():
    request = get_current_request()
    if request:
        return getattr(request, 'user', None)

class ThreadLocalMiddleware(object):
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        _thread_locals.request = request
        return self.get_response(request)

Also there is option like

pip install django-crum

and then,

# settings.py
MIDDLEWARE_CLASSES = (
     'crum.CurrentRequestUserMiddleware',
    ...
)

I hope this will help !
