[Answer]-Django foreign key is not set and hence unable to save form

I’m assuming you do not want to display the product field on the form, so you should exclude it from the form so the validation will pass:

class ResourceForm(forms.ModelForm):
    resource = forms.MultipleChoiceField(choices=ProductResource.CHOICES, widget = forms.CheckboxSelectMultiple)
    class Meta:
        model = ProductResource
        exclude = ['product']

Then in the view, just set the product manually after calling is_valid(). Just be sure to pass commit=False on the form.save() so that it will not actually save to the database until after you set the product. For example

...
saved_publication = publications_form.save()

resource_form = ResourceForm(request.POST)
if resource_form.is_valid():
    resource = resource_form.save(commit=False)
    resource.product = saved_publication
    resource.save()
