Becareful using int() or Decimal() for validation storing in Charfield Django

So, we have CharField() as model field in Django. Then we want to validate input into number only.
Usually, we using obj.is_digit() to validate.

Common mistake happen when we using int() to convert string input.

2
value = "0123123123"
int(value)

Will return

1
"123123123"

So becareful when using int() or Decimal() for converting value with leading zero
