If that field has unique values, probably you can use that fileld as primary
key.

Hello
In django admin, I have a model with a model fiel "tech_number" which must be
unique across the table. If I do not check the uniqueness, it raises a Django
integrity error. According to the documentation it sounds normal.
I checked the uniqueness of the" tech_number" in the clean of the model form.
but now it raises a validation error even in the change form. In fact it should
ask if I needs to erase the existing one.
What did I miss?
