            ...

    form = AuthenticationForm()

    args = {}
    args.update(csrf(request))
    args['form']= AuthenticationForm()

    return render_to_response('ownsite/access_ownsite.html', args)#accounts/login.html
def my_view(request):

You are using the same form for both register and login. Set different names for the forms in the template context.

Hmm I forget about it but I change names on form_l and form_r and effect is the same, I had also info

C:\Python34\lib\site-packages\django\template\defaulttags.py:66: UserWarning: A {% csrf_token %} was used in a template, but the context did not provide the value. This is usually cause

It's a good idea to use render() instead of render_to_response(), see https://docs.djangoproject.com/en/1.8/topics/http/shortcuts/#render. That will fix the issue with the CSRF token. render() takes the request as the first argument, and uses a RequestContext. This is needed to run the context processors, which add the csrf_token to the template.

You should send both forms to the context, as in:


args['form_login'] = AuthenticationForm()
args['form_register'] = UserCreationForm()

And change the template to the appropriate form names. Also, change {% if user.is_authenticated == False %} to {% if not user.is_authenticated %}.
