get foreign key from model

I want to get pk from model.

model.py

class Produit(models.Model):
    ref=models.CharField(max_length=100, default='',primary_key=True)
    marq=models.CharField(max_length=100, default='')
    nomp=models.CharField(max_length=100, default='')
    qte = models.IntegerField(default=0)
    codecateg=models.ForeignKey(categorie, on_delete=models.CASCADE)

class categorie(models.Model):
    codecateg=models.CharField(max_length=100, default='' , primary_key=True)
    nomcat=models.CharField(max_length=30, default='' )

views.py

def edit_prod(request , id = None):
    ins = get_object_or_404(Produit,ref=id)
    datedit = {'ins': ins}
    return render(request, 'produit/modal_prode.html',datedit )

When I want to get ins.codecateg I get categorie object.

In 'produit/modal_prode.html' you are sending Produit object, so ins is the object, and when you do ins.codecateg it will get the categorie object associated with it, but if you wnat to get the categorie pk you would have to

<h4>{{ ins.codecateg.pk }}</h4>

in html.
