Is there any example I can read to do the same thing? I want to email M2M content after an instance save. I thought a post_save should be raised when M2M field table update is completed. Is there any way to make a method call after that? -- Alessandro Ronchi Skype: aronchi http://www.alessandroronchi.net SOASI Soc.Coop. - www.soasi.com Sviluppo Software e Sistemi Open Source Sede: Via Poggiali 2/bis, 47100 Forlì (FC) Tel.: +39 0543 798985 - Fax: +39 0543 579928 Rispetta l'ambiente: se non ti è necessario, non stampare questa mail --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
