here want insert data directly table ,if person click on http://127.0.0.1:8000/

but throws below error thoughts ??

exception type: valueerror @ / exception value: cannot assign "u'x'": "working.w_name" must "profile" instance.

i thought saying wanted inject values form?

in case, it's clear (see it's better comments), need pass in profile instance working object did in form clean method in other post.

def index(request):    try:         profile = profile.objects.get(pk='x')    except profile.doesnotexist:        assert false # or whatever wish    obj=working()    obj.w_name= profile    obj.monday=1    obj.tuesday=2    obj.wednesday =3    obj.save()    return http.httpresponse('added')
