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 %}

You can use a custom tag for that case. Check this . I also had to build it for my project as I had to send arguments from template to my model's method. I created a folder in my app called templatetags and inside that folder was my __init__.py and myTags.py :

from django import template

register = template.Library()

@register.simple_tag
def call_method(obj, method_name, *args):
    method = getattr(obj, method_name)
    return method(*args)

then in template first I import my tags then I use my custom tag:

{% load myTags %}


{% call_method model 'method' argument1 argument2 argument3... %}
