Django admin - add more controls to the field

The goal is to add custom input and a button to Django admin panel. It is described on the image (marked with green):

enter image description here

The problem is that Django admin uses database to display its stuff. Inline components doesn't fit here, because the rest of the rows don't have these controls.

Try this:

from django.contrib.auth import forms
import datetime

class AddDaysForm(forms.ModelForm):
    add_extra_days_to_subscription_expiry = forms.IntegerField(required=False)

    class Meta:
        fields = '__all__'

    def __init__(self, *args, **kwargs):
        instance = kwargs.get('instance')
        if instance:
            self.base_fields['add_extra_days_to_subscription_expiry'] = 0
        forms.ModelForm.__init__(self, *args, **kwargs)

class SubscriptionAdmin(admin.ModelAdmin)
    form = AddDaysForm
    list_display = ('id', 'domain', 'domain_created',)

    def save_model(self, request, obj, form, change):
        if form.cleaned_data['add_extra_days_to_subscription_expiry'] != 0:
            obj.subscription_expire = obj.subscription_expire + datetime.timedelta(days=form.cleaned_data['add_extra_days_to_subscription_expiry'])
            obj.save()

With this solution, you simply enter a number and then hit save via the admin, and it will add it for you. When the form reloads, it will reset back to 0 so that you can enter a new value. Note, that it also accounts for when the form is saved from the default '0' value.
