If you actually are inside the profile create view, the profile probably
does not have an id yet and thats why the url lookup is failing. The ID
will be created on first save of the object.

Well, is it actually named profile inside the view? Rather than the default
original? Check if the name is right and your profile is named profile in
the template.

which one of your calls to detail are failing?

<a href="{% url 'student:detail' profile.id %}">

or

reverse('student:detail', kwargs={'pk': self.pk})

?


if its the second one, try with args=[self.pk]

Post by a***@gmail.com
Yes it is named profile.

Well, is it actually named profile inside the view? Rather than the
default original? Check if the name is right and your profile is named
profile in the template.

Post by a***@gmail.com
The profile already have an id. Just wanted to add to an existing profile
in the db with generic view.

If you actually are inside the profile create view, the profile probably
does not have an id yet and thats why the url lookup is failing. The ID
will be created on first save of the object.

which one of your calls to detail are failing?<a href="{% url 'student:detail' profile.id %}">orreverse('student:detail', kwargs={'pk': self.pk})?
if its the second one, try with args=[self.pk]

Well, is it actually named profile inside the view? Rather than the default original? Check if the name is right and your profile is named profile in the template.

The profile already have an id. Just wanted to add to an existing profile in the db with generic view.

If you actually are inside the profile create view, the profile probably does not have an id yet and thats why the url lookup is failing. The ID will be created on first save of the object.
