在Django的管理面板中添加逻辑

Question

I have two models, the second model is FK from my first model like this:

class Model0(models.Model):
    work = models.FloatField(blank=True, null = True)

class Model1(models.Model):
    class Meta:
    unique_together = (('lat', 'lng'),)
    lng = models.FloatField(blank=True, null=True)
    lat = models.FloatField(blank=True, null=True)

class Model2(models.Model):
    idWork    = models.ForeignKey('Model0', on_delete=models.CASCADE)
    idSTFolio = models.OneToOneField('Model1', on_delete=models.CASCADE)

I use admin panel to add my data, I need that when I add a second (Model0, Model1) with others values to Model1, in my Model2 this association was created automatically like this:

for example:

Model2 : (Model0, Model1)

Id 1 : (1.5, (2.5, 3.0)) , 1.5 is 'Work' from Model0 and (2.5, 3.0) lat and lng in Model1

I need something like this...in this moment I create other Model1 with these values (2.5, 4.0), so like lat: 2.5 has already been added in Model2 I need that in my Model2 add other row like this automatically :

Id 1 : (1.5, (2.5, 3.0)) Id 2 : (1.5, (2.5, 4.0))

Any idea if it is possible to modify the admin panel for what I need? In this moment I must add this association in my Model2 page in admin panel, but It not is my idea.

I just googled for multi-level inlines and found django-nested-inline package .

It seems promising to me for your purpose. I have found this in many stackoverflow answers as well:

I have never tried this package but I think, this will work for you. Please let me know if it works for you.
