 1 | A tiny app adding support unlimited ``varchar`` fields (no specified max length) in Django/Postgres.
 2 | 
 3 | Usage::
 4 | 
 5 |     from django.db import models
 6 |     from django_postgres_unlimited_varchar import UnlimitedCharField
 7 | 
 8 |     class Person(models.Model):
 9 |         name = UnlimitedCharField()
10 |         ...
11 | 
12 | Why?
13 | 
14 | Out of the box, Django has two fields for text:
15 | 
16 | * ``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)``.
17 | * ``TextField``, which is for multi-line text, and has no maximum length. In the database, this creates a field of type ``text``.
18 | 
19 | Clearly missing is a third type: single-line, no max length. Postgres supports this as the ``varchar`` type (note the lack of a length).
20 | 
21 | 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.
