Show data from specific table in my view django - django

Question

I want only the requests from the Hospital.
How can I achieve this?
Example:
User from Hospital
class CustomUser(AbstractBaseUser, PermissionsMixin):
email = models.EmailField(_('email address'), unique=True)
FKbelongs_to = models.ForeignKey('HospitalViewRoleForUsers', on_delete = models.CASCADE, null=True, blank=True)
Hospital Model
class HospitalViewRoleForUsers(models.Model):
RequestsFromLab = models.ForeignKey('request', on_delete=models.PROTECT)
Requests from the Hospital
FKHospitalRequests = models.ForeignKey('HospitalViewRoleForUsers', on_delete = models.PROTECT)
user_request = models.ForeignKey('customuser', on_delete= models.PROTECT)
In my View I need to validate which Hospital the user belongs to and,
Pass only the request information from that hospital to my user view.
The user view that I am trying to build
def Get_UserRequestByHospital(request, pk):
user = request.user
items = requests.objects.filter(FKHospitalRequests = 1).values_list('id', flat = True)
return render(request, 'user_profile/list-user-request.html', {'items': items})
In Jupyter testing data it appears like this
user_hospital2 = requests.objects.filter(FKHospitalRequests = 1).values_list('id', flat = True)
<QuerySet [1]>
As we can see, Jupyter returns the request id. Which is linked to the Hospital. But, I am confused and I need help thinking on a solution. I am new to Django, so. I suppose I need to pass the PK to the view, and then, create a filter to check if PK is equal to FK from the Hospital Request? But, also, How I know this user belongs to the Hospital? Thank you. I am really lost and I am new to Django.
-- Edit: Users from the same hospital can see others users requests.

Answer 1

I solved by doing this:
In my view of requests I added a FK to check if is equal to the User FK.
With this method I can make only users from Hospital 1, to see the requests of Hospital 1.
def Get_UserRequest(request, FKbelongs_to_id):
user = request.user
if CustomUser.objects.filter(FKbelongs_to_id = FKbelongs_to_id):
items = requests.objects.filter(FKHospitalRequests_id = FKbelongs_to_id)
else:
return HttpResponseNotAllowed("Not Allowed")
