Hi, I've done something similar just recently where I generate a "key" field in a ModelAdmin to display in django admin.
> from django import forms > from django.contrib import admin class MyForm(forms.ModelForm): > key = forms.CharField(max_length=256) > def __init__(self, *args, **kwargs): > super(MyForm, self).__init__(*args, **kwargs) > self.fields['key'].initial = self.instance.key > > class MyModelAdmin(admin.ModelAdmin): > form = MyForm > def save(self, request, obj, form, change): > # save > if "key" in self.form.cleaned_data: > del self.form.cleaned_data['key'] > super(MyModelAdmin, self).__init__(request, obj, form, change) > admin.site.register(MyModel, MyModelAdmin) In the save method of MyModelAdmin you can do your logic that you have mentioned.
