How to define a relationship object for a model in django?

Question

Django

There are two models:

from django.db import models

class Category_item(models.Model):
  name_category = models.CharField('Название категории', max_length=100)

class Item(models.Model):
  name = models.CharField('Название пункта', max_length=100)
  description = models.TextField('Описание пункта')
  Category_item = models.ForeignKey(Category_item, on_delete=models.CASCADE, null=True, blank=True)

Let's say, given that Category_item has the blank=True attribute, I haven't defined the link, and now I need to define it without the admin panel, through some function.
I will be grateful for any answer
