I’m creating a django based web app and I have used Auth > User model (without any customization except password hiding) and for user detail I have created another model ChangeShift. and model based form.
Case 1: When I am using alluser = ShiftChange.objects.all() I'm able to see all the data available in ShiftChange model.
Case 2: Now I want that when user is logging, he should be able to see data related to his name and I'm using this:
def retrieve_view(request):
# alluser = ShiftChange.objects.all()
alluser = ShiftChange.objects.filter(ShiftChange.ldap_id == request.user.username)
return render(request, 'apple/shift2.html', {'alluser': alluser})
For this code I am getting error:
cannot unpack non-iterable bool object

TypeError: cannot unpack non-iterable bool object
The line:
alluser = ShiftChange.objects.filter(
ShiftChange.ldap_id == request.user.username)
is the error. The part ShiftChange.ldap_id == request.user.username is an expression that evaluates to True or False, and then your code becomes equivalent to
alluser = ShiftChange.objects.filter(True)
or
alluser = ShiftChange.objects.filter(False)
and that is probably not what you want.
Try using a single = sign and use a valid left side kwarg (because ShiftChange.ldap_id with the dot in the middle is not valid here). So your code may end up similar to this:
alluser = ShiftChange.objects.filter(ldap_id=request.user.username)
