Problem with safedelete implementation


I am new on this forum and very, very new user of Django so hope you will be uncensorious

I need to implement the safedelete application ( for my project but I should have miss something in the documentation because I did non manage tu use it correctly

I will expose you briefly my problem
I have 2 classes BiologyAssessment and BiologyExam linked with a foreignKey: a biologicalassessment is linked with multiple biologicalexam

When I delete a biologicalassessment, I want related biologicalexamn to be 'delete' (but soft delete)
When I delete a biologicalexam, I want biologicalexam to be delete (soft delete)

I have implemented in my project but unfortunetly, when I delete a biologicalexam, the linked biologicalasessment is also delete
I have try different to use _safedelete_policy = SOFT_DELETE for my BiologicalExam class but it does not chage anything

could you help me ?

class BiologicalAssessment(SafeDeleteModel):

    _safedelete_policy = SOFT_DELETE_CASCADE
    ide = models.AutoField(primary_key=True)
    vis_ref = models.ForeignKey(Visite, verbose_name='Visite', related_name='bilan', on_delete=models.CASCADE)
    bio_prv_dat = models.DateField("Date de prélèvement")

class BiologicalExam(SafeDeleteModel):

    _safedelete_policy = SOFT_DELETE_CASCADE
    ide = models.AutoField(primary_key=True)
    bio_ref = models.ForeignKey(BiologicalAssessment, verbose_name='Bilans', related_name='examen', on_delete=models.CASCADE)
    bio_exa_cod = models.CharField("Type d'examen", max_length=3)
    bio_exa_val = models.FloatField("Résultat de l'examen")
    bio_exa_uni = models.CharField("Unité", max_length=50)
    bio_exa_val_inf = models.FloatField("Limite inférieure")
    bio_exa_val_sup = models.FloatField("Limite supérieure")
