Django Import Export, Filter ForeignKey objects connected to users

[Gianmaria Di Fronzo]

I'm building an import excel files system for every leads whit import export library. In the Website each user must be able to import his leads and make sure that they are viewed only by him. In all other cases I filtered the "organisation" field linked to a UserProfile model through the views.py. But now I don't know how to filter the field organisation for a specific user.At the moment I can import the excel files from the template but leaving the organisation field blank. Help me please I'm desperate

Models.py

class Lead(models.Model): 

nome = models.CharField(max_length=20)

 cognome = models.CharField(max_length=20)

 luogo=models.CharField(max_length=50, blank=True, null=True, choices=region_list) città=models.CharField(max_length=20) email = models.EmailField() 

phone_number = models.CharField(max_length=20)

 description = models.TextField() 

 agent = models.ForeignKey("Agent", null=True, blank=True, on_delete=models.SET_NULL) 

category = models.ForeignKey("Category", related_name="leads", null=True, blank=True, on_delete=models.SET_NULL) chance=models.ForeignKey("Chance",related_name="chance", null=True, blank=True, on_delete=models.CASCADE) 

profile_picture = models.ImageField(null=True, blank=True, upload_to="profile_pictures/") converted_date = models.DateTimeField(null=True, blank=True) 

date_added = models.DateTimeField(auto_now_add=True) 

organisation = models.ForeignKey(UserProfile, on_delete=models.CASCADE,null=True, blank=True) 

 objects = LeadManager() 

age = models.IntegerField(default=0) def __str__(self): return f"{self.nome} {self.cognome}" 

 class User(AbstractUser): 

is_organisor = models.BooleanField(default=True)

 is_agent = models.BooleanField(default=False)

 class UserProfile(models.Model): 

  user = models.OneToOneField(User, on_delete=models.CASCADE)

 def __str__(self): return self.user.username

Views.py

def simple_upload(request):

  if request.method == 'POST': 

 Lead_resource = LeadResource()

 dataset = Dataset() 

 newdoc = request.FILES['myfile'] 

 imported_data = dataset.load(newdoc.read(),format='xlsx') 

  #print(imported_data) 

  for data in imported_data: 

 value = Lead( data[0], data[2],#nome data[3],#cognome data[5],#luogo data[7],#città data[8],#email data[9],#numero telefono data[11],#desc ) value.save() 

 result = Lead_resource.import_data(dataset, dry_run=True) # Test the data import if not result.has_errors(): 

 Lead_resource.import_data(dataset,dry_run=False) # Actually import now return render(request, 'input.html')

Resources.py

class LeadResource(resources.ModelResource):
