is there another REGEX way (or another way) to ensure that a model class field would be unique? (it is not a key, or at least not declared as a key, is shoulb be a simple CharField)
Thanks

Of course, you should have an id tag, which is always unique, because it's a primary key. However, certain fields may also need to be unique, because certain fields may need to be unique without any repetition. So, to make a field unique in Django is very basic. You just set the unique attribute to true.
app_label is used when you have models in a place in which django doesn't know to which app they belong.
unique=True sets the field to be unique i.e. once entered a value in a field, the same value can not be entered in any other instance of that model in any manner. It is generally used for fields like Roll Number, Employee Id, etc which should be unique.
What is SlugField in Django? It is a way of generating a valid URL, generally using data already obtained. For instance, using the title of an article to generate a URL. Let's assume our blog have a post with the title 'The Django book by Geeksforgeeks' with primary key id= 2.
The normal way to make a single field unique is to use the unique argument to the field constructor.

If you need to make this unique on more than one field, have a look at: unique-together
