How i can to pass parameter to model method in django template?

Question

Hi everyone i have a question about django template and models method include function parameter.

example code in models.py

class Item(models.Model):
     name = models.CharField(max_length=30)
     price = models.IntegerField()
     owner = models.ForeignKey('User',on_delete=models.CASCADE)

     def get_something(self,requestuser): # <-- pass request.user here
         // calculate something here 
         return "output"

in views.py

def assets(request):
     return render(request, 'index.html', {'items':Item.objects.filter(owner=request.user)})

in template

{% for item in items %}
   <h1>{{item.name}}</h1>
   <h2>{{item.price}}</h2>
   <h2>{{item.get_something(request.user) }}</h2> <!-- How to inject request.user to get_something Here -->
{% endfor %}

I found out what was my problem finally: We have a cache for our apis, and that prevented the react query to make a new request. so I sent a param to the api when I'm calling it as below:

    const res = await api.get_vouchers({ orderby: 'created_at desc', top: '50', cache: false });
