class YourView(FormView): form_class = YourForm ... def get_form_kwargs(self): kwargs = super(YourView, self).get_form_kwargs() kwargs['user'] = self.request.user return kwargs
In other scenario, initiate form with passing known argument
def some_view(request): form = YourForm(request.POST, user=request.user)
django: how to access current request user in ModelForm?, you need to have a __init__ method in the model form class, and you access the request or other parameters from the arguments of the __init__ method, then you need to call the super constructor to new up the form class. and then you set the queryset of the required field. To add to @EAMann's answer, you need to wrap your wp_get_current_user() call (or any call that tries to access a function defined within pluggable.php) within the 'plugins_loaded' action.
f = MyForm(user=request.user) // where you are calling the form in the view
and the constructor will look like:
class MyForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.user = kwargs.pop('user',None) super(MyForm, self).__init__(*args, **kwargs)

from __future__ import absolute_import, division, print_function try: from threading import local except ImportError: from django.utils._threading_local import local _thread_locals = local() def get_current_request(): """ returns the request object for this thread """ return getattr(_thread_locals, "request", None) def get_current_user(): """ returns the current user, if exist, otherwise returns None """ request = get_current_request() if request: return getattr(request, "user", None) class ThreadLocalMiddleware(object): """ Simple middleware that adds the request object in thread local stor age.""" def process_request(self, request): _thread_locals.request = request def process_response(self, request, response): if hasattr(_thread_locals, 'request'): del _thread_locals.request return response
Then, config your setting file:
MIDDLEWARE = [ ... 'YOUR_PROJECT_NAME.middleware.ThreadLocalMiddleware', ]
Use the function get_current_user() anywhere you want to get curent user. Example models.py:

- You have to pass the user to the form obviously -
kwargs.pop('user',None)will not automagically insert
userin kwargs if it's not been passed.
- This is a link only answer. Please take (at least) the parts that are required for a minimal working opy from the link and add it to your answer in case the link might become broken in the future.
- You should give proper attribution (at least the link to where you got this antipattern recipe from) - but it's really an antipattern, Django has been specifically designed to properly decouple the domain from the request/response cycle so your domain code doesn't NEED a request to work (which is the RightThing(tm) to do).
