[Fixed]-Why are my model restrictions ignored?

✅

  1. The empty value of a CharField is the empty string ''.

  2. You do not actually set the code field. What your are actually doing is setting the id.

    >>> co = Code("1234567891011")
>>> co.id
"1234567891011"

    Try:

    co = Code(code="1234567891011")
co.save()

    or, if you really do not want to use keyword arguments:

    co = Code(None, "1234567891011")

    It will raise an exception if you use a database that enforces length constraints (some databases, e.g. SQLite, don’t).
