Hi
I read your requirement, and I think you are trying to run some logic when a model object is being saved. Signals is the best way to do this.
I have implemented Signals in many of my Django projects. So, I can fulfill your requirement in the least amount of time. I can show you my most recent project in case you want.
100% satisfaction guaranteed. You can pay me only if you are satisfied.
Thanks
Sai Shiva
