Django:The QuerySet value for an exact lookup must be limited to one result using slicing

I am working on a project where admin can assign team to manager. But it is not working and i have no idea how it will work. Because it is raising an error saying "The QuerySet value for an exact lookup must be limited to one result using slicing."

Here is my model.py

class manager(models.Model):
name = models.CharField(max_length= 500)
designation = models.CharField(max_length= 500)
user = models.ForeignKey(User,on_delete=models.CASCADE)
class Meta:
    permissions = [
        ("edit_task", "can edit the task"),
here is my views.py file for the teams of manager
@login_required (login_url= 'have the url where it will go')
@permission_required('have the permission that is assigned by me')
def supervisor(request):
return render(request, 'manager/index-3.html')
def supervisor_team(request):
print(request.user.email)
email=request.user.email
obj= Create_Team.objects.filter(status='Accept', 
managers=manager.objects.filter(user__email=email))
return render(request, "manager/accept_team.html", {"object": obj})
here is my template
<div class="body table-responsive">
                        <table class="table table-hover">
                            <thead>
                                    <th>S No.</th>
                                    <th>COMPANY NAME</th>
                                    <th>TEAM MEMBER</th>
                                    <th>EMAIL</th>
                            </thead>
                            <tbody>
                                    {%for object in team%}
                                        <form id="form_id" method="POST" action = "#">
                                            {% csrf_token %}
                                    <th scope="row"> {{ forloop.counter }}</th>
                                    <td>{{object.company_name}}</td>
                                    <td>{{object.team_member}}</td>
                                    <td>{{object.email}}</td>
                                {% endfor %}
                            </tbody>
                        </table>
I have no idea where i am wrong.
                Please share your Create_Team model. I guess you are passing queryset of manager but need to pass one instance of manager`

obj= Create_Team.objects.filter(status='Accept', 
managers=manager.objects.filter(user__email=email))
if you want to filter by one manager you have to use get instead of filter:
obj= Create_Team.objects.filter(status='Accept', 
managers=manager.objects.get(user__email=email))
But if you want to filter by several managers you need to use __in:
obj= Create_Team.objects.filter(status='Accept', 
managers__in=manager.objects.filter(user__email=email))
Also you are passing {"object": obj}) to template but in templare you are trying to iterate over team. So change it to pass team variable:
return render(request, "manager/accept_team.html", {"team": obj})
                yes it works for me but i have an another problem that the teams is not showing in the UI

                So please add your template as well here. And print obj before rendering in order to check if it's empty or not.
