AttributeError: 'bytes' object has no attribute - django

Question

I have a class in which I am checking user permissions, and depending on them, I return a list of results from models. Here is what I have:
from AnnualLeave.models import Leaves, RejectedLeaves, Employee
class GetLeaves:
def get_results(request):
try:
if request.user.groups.filter(name__in=['SuperAdmin']).exists():
return Leaves.objects.all()
elif request.user.groups.filter(name__in=['Admin']).exists():
return Leaves.objects.filter(employee_id=Employee.objects.get(manager_id=request.user.pk))
else:
messages.error(request, "You are not allowed on this page")
return render(request, 'users/home.html')
except (Leaves.DoesNotExist, Employee.DoesNotExist):
return []
def process_results(request):
leave_request = []
for leave in GetLeaves.get_results(request):
content = {'emp_id': leave.employee_id,
'emp_name': Employee.objects.get(user_id=leave.employee_id).user.get_full_name(),
'start_date': leave.start_date,
'end_date': leave.end_date,
'reason': leave.get_reason_display(),
'description': leave.description,
}
....
leave_request.append(content)
return leave_request
And then I'm calling process_results function in TemplateView like this:
class ProcessLeaveRequest(TemplateView):
template_name = 'LMSAdmin/process_leave_request.html'
def get(self, request, *args, **kwargs):
return render(request, self.template_name, {'leave_requests': GetLeaves.process_results(request)})
Here is a traceback of error:
Internal Server Error: /lms_admin/upcomingleaves/

AttributeError: 'bytes' object has no attribute 'employee_id'
From what I can see, it is reading the entire webpage with the request parameter in functions. Like the get_results function is not returning a list, but the entire webpage. I do not understand why this is happening because it was working fine before without any changes.

Answer 1

You should not return a HttpRequest from get_results. Instead raise a PermissionDenied error.
else:
from django.core.exceptions import PermissionDenied
messages.error(request, "You are not allowed on this page")
raise PermissionDenied
If you want to redirect to a different page, handle that in the view. You can capture the PermissionDenied and return the redirect.
