How to save uploaded image url in database from Django?

[PrateekG]

Try this:

class Brand(models.Model):

    name = models.CharField(max_length=60)
    description = models.TextField(blank=True, null=True)
    image_url = forms.CharField(widget=forms.HiddenInput())
    created_at = models.DateTimeField(auto_now_add=True, editable=False)
    updated_at = models.DateTimeField(auto_now=True)

    @property
    def logo(self, folder):
        logo_name_with_ext = '{}{}'.format(self.name, '.png')
        self.image_url = '{}/{}'.format(IMAGE_PATH, os.path.join(folder, logo_name_with_ext))
        return mark_safe('<img src="{}" height="20" />'.format(logo_url))

    class Meta:
        managed = False
        db_table = 'brand'

    def __str__(self):
        return self.name


new_brand = Brand()
new_brand.name = "Brand Name"
new_brand.description = "Brand Description"
html_img_tag = new_brand.logo('brand')
new_brand.save()

I am unable to understand the relationship between image_url and logo here-

new_brand = Brand()
new_brand.name = "Brand Name"
new_brand.description = "Brand Description"
html_img_tag = new_brand.logo('brand')
new_brand.save()

And if I add below line-

image_url = forms.CharField(widget=forms.HiddenInput())

It says

Error:
unresolved reference 'forms'

Once I change it to models, it says

Error:
AttributeError: module 'django.db.models' has no attribute 'HiddenInput'

For workaroung I movedd your changes in my forms.py as below-

class BrandForm(forms.ModelForm):
    logo = forms.ImageField(required=False)
    image_url = forms.CharField(widget=forms.HiddenInput())

    class Meta:
        model = Brand
        fields = '__all__'

    def clean_logo(self):
        valid_extensions = ['.png', '.jpg', '.jpeg']
        name = self.cleaned_data.get('name')
        logo = self.cleaned_data.get('logo')

        if logo:
            image_processor = ImageProcessor(logo)
            image_url = image_processor.upload(name, 'brand', valid_extensions)
            new_brand = Brand()
            new_brand.image_url = image_url
            new_brand.save()
        print('image_url is',image_url)
        return logo

But when I click on the save button, it says

Error:
Please correct the error below

Neither in server nor in log file there is any error.
