django-postgres-unlimited-varchar 1.1.2

A tiny app adding support unlimited varchar fields (no specified max length) in Django/Postgres.

Usage:

from django.db import models
from django_postgres_unlimited_varchar import UnlimitedCharField

class Person(models.Model):
    name = UnlimitedCharField()
    ...

Why?

Out of the box, Django has two fields for text:

• CharField, which is for single-line text, and has a required maximum length (the max_length argument). In the database, this creates a field of type varchar(LENGTH).

• TextField, which is for multi-line text, and has no maximum length. In the database, this creates a field of type text.

Clearly missing is a third type: single-line, no max length. Postgres supports this as the varchar type (note the lack of a length).

This field adds that type. AFAIK there isn’t any performance hit in using this, so it’s suitable for any situation where there isn’t a clear required max length.
