Plugins Developement | Create instance with ManyToMany fields

[AVariot]

Hi !

Actually my plugins is using model.ManyToMany fields. When i want to create a new objects i have 'ManyRelatedManager' object has no attribute 'pk'. I think i need to rewrite the save methode but it doesn't work.

If i do that : " def save(self, commit=True, *args, **kwargs):
facture = super(FactureForm, self).save(commit=False, *args, **kwargs)
facture.date_facture = self.cleaned_data.get('date_facture')
facture.numero_facture = self.cleaned_data.get('numero_facture')
facture.commande = self.cleaned_data.get('commande')
return facture" i got this : "Operation failed due to object-level permissions violation"

Someone could help me, and tell me how can i rewrite the save methode (if it's that what i need)

Thank you
