Question

    precursor = models.ManyToManyField(Precursor)

class ReportAdmin(admin.ModelAdmin):
    def formfield_for_manytomany(self, db_field, requ         


        

Answer 1

Assuming you're after the Report instance being edited by the ReportAdmin, try this:

class ReportAdmin(admin.ModelAdmin):
    def get_object(self, request, object_id):
        # Hook obj for use in formfield_for_manytomany
        self.obj = super(ReportAdmin, self).get_object(request, object_id)
        print "Got object:", self.obj
        return self.obj

    def formfield_for_manytomany(self, db_field, request, **kwargs):
        if db_field.name == "r_precursor" and getattr(self, 'obj', None):
            kwargs["queryset"] = Precursor.objects.filter(
                ops_area=self.obj.ops_area)
        return super(ReportAdmin, self).formfield_for_manytomany(
            db_field, request, **kwargs)
