Linking an Image detection Project to Django

Hi,

I am working on a colour detection project and I am trying to link it to my Django Project, but I don't know where to start.

In my Django project, I have a Post CreateView where users can upload images.

Here is the function that I am trying to link the colours in the image to Post.colors but I don't know how to make it generated directly once the image is uploaded

Here is the models.py:

```

class Post(models.Model):

    title = models.TextField(max_length=100)

    design = models.ImageField(

        blank=False, null=True, upload_to='new designs')

    date_posted = models.DateTimeField(default=timezone.now)

    colors= models.TextField(max_length=10,blank=True, null=True)

    def __str__(self):

        return self.title

    def imagecolors(self, *args, **kwargs):

        img = Image.open(self.design)

        size = w, h = img.size

        data = img.load()

        colors = []

        for x in range(w):

            for y in range(h):

                color = data[x, y]

                hex_color_lower = ''.join([hex(c)[2:].rjust(2, '0') for c in color])

                hex_color = hex_color_lower.upper()

                colors.append(hex_color)

        total = w * h

        color_hex = []

        color_count = []

        color_percent = []

        df = pd.DataFrame()

        for color, count in Counter(colors).items():

            percent = count / total * \

                      100  # Do not make it int. Majority of colors are < 1%, unless you want >= 1%

            if percent > 1:

                color_hex.append(color)

                color_count.append(count)

                color_percent.append(percent)

            Post.colors=color_hex

            print(Post.colors)

```

with the above it showing none in the template:

```

{{ post.colors }}

```
