Save only specific fields in form

Using Django Forms & APIs
1

I have the following form:

class PostForm(forms.ModelForm):
    class Meta:
        model = Post
        fields = ['title', 'main_image', 'related_to']

post method in views class

    def post(self, request, pk):
        form=PostForm(instance=self.post,data=request.POST,files=request.FILES)
        if form.is_valid():
            form.save()
        else:
            print(form.errors)
        return redirect('post_detail_change', self.post.id)

and in template

<form action="" method="post" enctype="multipart/form-data">
            {{contact.title}}
            {% csrf_token %}
 </form>
<form action="" method="post" enctype="multipart/form-data">
            {{contact.main_image}}
            {% csrf_token %}
</form>
<form action="" method="post" enctype="multipart/form-data">
            {{contact.related_to}}
            {% csrf_token %}
</form>

and i have a js code that sends a post request when any of the 3 forms are changed.

for (let i=0; i < forms.length; i++) {
    forms[i].addEventListener('change', function (e) { 
    this.submit()
    })
}

So, my problem is that i trying to save, for example, ‘main_image’ field, it fails because it reques ‘title’ field. How can i handle it?

You’re trying to use one Django form for three different HTML forms.

You likely either need to create three different Django forms, or change your submission process to submit the selected element as a JSONish or RESTish submission identifying the field being updated and the new value for that field.
