Question

class ServiceInline(admin.TabularInline):
    model = Service

class PlanAdmin(admin.ModelAdmin):
    inlines = [ServiceInline]

class ServiceAdmin(admin.ModelAdmin):   
    def save_model(self, request, obj, form, change):
        instance = form.save(commit = False)
        if not instance.created_at and not instance.modified_at:
           instance.created_by = request.user
        instance.modified_by = request.user
        instance.save()        
        form.save_m2m()
        return instance

I have overrided the save_model(self, request, obj, form, change): method of Service class in it’s admin class. But this overrided method is not getting called when a Service object added via Inline (Plan’s page). Any suggestions?

Answer 1

Rather than using the save_model function in the admin, which I don’t think is going to work, what about the following:

class PlanAdmin(admin.ModelAdmin):
    # ...
    def save_model(self, request, obj, form, change):
        instance = form.save(commit=False)
        instance.last_updated_by = request.user
        instance.save()

class Service(models.Model):
    # ...
    created_by = models.ForeignKey(User, blank=True)

    def save(self, *args, **kwargs):
        self.created_by = self.plan.last_updated_by
        super(Service, self).save(*args, **kwargs)
