      #img = make_square(img, 1080, 1080)
      img.save(self.image.path)

creat-post.html

{% extends "home/base.html" %}
{% load crispy_forms_tags %}
{% block content %}
   <div>
      <form method="POST">
         <fieldset>
            <legend >Creat Post</legend>
            {% csrf_token %}
            {{ form|crispy }}
         </fieldset>
         <button class="btn btn-primary" type="submit">Post</button>
      </form>

   </div>
{% endblock %}

So I created a creatview to add create new post. However when I go to the link and add photo then hit submit, it gives me as I haven't uploaded an image.

However, I am able to add images to a new Post from the admin normally.
