Форма не проходит валидацию django

Форма не проходит валидацию и на html странице пишет ошибку "This field is required."

forms.py:

class PostCreateForm(forms.ModelForm):
    class Meta:
        model = Image
        fields =('image','title', 'description')

models.py:

class Image(models.Model):

    slug = models.SlugField(max_length=200, blank=True)

    image = models.ImageField(upload_to='images/%Y/%m/%d/')
    description = models.TextField(blank=True)
    created = models.DateField(auto_now_add=True, db_index=True)
    users_like = models.ManyToManyField(settings.AUTH_USER_MODEL, related_name='images_liked', blank=True)

    def __str__(self):
