I am working on Django project I receive the following error:

ValueError at / The 'image' attribute has no file associated with it.

models.py:

from django.contrib.auth.models import User
from django.db import models

# Create your models here.
class Category(models.Model):
    name = models.CharField(max_length=255)

    class Meta:
        ordering = ('name',)
        verbose_name_plural = 'Categories'

    def __str__(self):
        return self.name

class Item(models.Model):
    Category = models.ForeignKey(Category, related_name='items', on_delete=models.CASCADE)
    name = models.CharField(max_length=255)
    description =models.TextField(blank=True, null=True)
    price = models.FloatField()
    image = models.ImageField(upload_to='item_images', blank=True, null=True)
    is_sold = models.BooleanField(default=False)
    created_by = models.ForeignKey(User, related_name='items', on_delete=models.CASCADE)
    created_at = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.name

html

    
        

            
{{ item.name }}
            
Price: {{ item.price }}
  
        
 

Error during template rendering.

How can I handle this error?
