How to save two models with a parent and child relationship simultaneously

Hi everyone,

I have 2 models(Riskassessment and Goal) that have a many to one relationships. I use a form for the riskassessment and a formset within that form for the goal. I wonder how to get the pk of the current riskassessment(the parent) into the formset(child) and be able to save both (formset and form) with one submit.
I haven’t add the jquery yet as I am still worry about saving the 2 objects
Please can you help me.
Here follow my files

class Customer(models.Model):
    first_name = models.CharField(max_length=100)

    communication_aids = models.BooleanField(editable=True, default=False)

Thank you

This is covered by the Saving objects in the formset section of the docs. You might also want to review the save() method on forms.
