Question

I know that with a regular string you can do x.len() to get the length of it, but a Django model TextField doesn’t seem to want that. I have found and looked at the model field reference. How do I get the length of a text field in Django? Help and examples appreciated.

Answer 1

Try len(obj.your_field). This should give you what you want because the result it going to be a an object of the corresponding data type (both TextField fields and CharField fields will be strings). Here is a quick example based on the docs:

from django.db import models

class Person(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)

 person = Person.objects.get(pk=1)

 len(person.first_name)

Also, there is no ‘string’.len() method in python unless you have added it somehow.
