The Python AztecGlyph package is a useful tool for generating unique and secure IDs and keys in the form of 64-bit UUIDs. The AztecGlyph class represents UUIDs that are immutable, hashable, and can be used as dictionary keys. Converting an AztecGlyph object to a string using str() yields a base58-encoded string (URL-safe) that is 11 characters long.
The AztecGlyph class constructor accepts four possible forms of arguments: a string (base58 encoded), a bytes object, an integer, a hexadecimal string, or the values for counter, content type, and timestamp.
The AztecGlyph UUID is divided into three parts: timestamp (41 bits), counter (11 bits), and content type (12 bits).
Property | Bits | Min | Max | description |
---|---|---|---|---|
Timestamp | 41 | 1577836800000 | 3776860055551 | The timestamp is the number of milliseconds elapsed since January 1, 2020. |
Counter | 11 | 0 | 2047 | The counter is a number incremented each time a new AztecGlyph is created and reset to 0 each time the timestamp is incremented. |
Content Type | 12 | 0 | 4095 | The content type is used to identify the type of data stored in the AztecGlyph. |
To use this package, you should have Python 3.x installed. You can install the package using pip:
pip install aztecglyph
from aztecglyph import AztecGlyph
# Create a new AztecGlyph from a base58-encoded string (11111111111 to jpXCZedGfVQ)
glyph1 = AztecGlyph(s=base58_string)
# Create a new AztecGlyph from a bytes object
# (b'\x00\x00\x00\x00\x00\x00\x00\x00' to b'\xff\xff\xff\xff\xff\xff\xff\xff')
glyph2 = AztecGlyph(b=byte_object)
# Create a new AztecGlyph from an integer (0 to 18446744073709551615)
glyph3 = AztecGlyph(i=integer_value)
# Create a new AztecGlyph from a hexadecimal string
glyph4 = AztecGlyph(h=hex_string)
# Create a new AztecGlyph with specific counter, content type, and timestamp values
glyph5 = AztecGlyph(counter=counter_value, content_type=content_type_value, now=timestamp_value)
The AztecGlyph class objects have several read-only attributes and methods:
Name | Return Type | Description |
---|---|---|
glyph.content_type |
int | Content Type ID |
glyph.str |
str | String 11 characters |
glyph.int |
int | Integer |
glyph.bytes |
bytes | Bytes object |
glyph.hex |
str | Hexadecimal string |
glyph.timestamp |
datetime | Timestamp |
glyph.datetime |
datetime | Datetime |
glyph.counter |
int | Counter |
AztecGlyph
objects can be compared using standard comparison operators such as==, <, <=, >, and >=`. For example:
# Equality check
if glyph1 == glyph2:
print("glyph1 is equal to glyph2")
# Less than check
if glyph1 < glyph2:
print("glyph1 is less than glyph2")
# Greater than or equal to check
if glyph1 >= glyph2:
print("glyph1 is greater than or equal to glyph2")
AztecGlyphField is a Django extension that enables seamless integration of the AztecGlyph library with Django models for generating unique and reliable 64-bit identifiers.
- Inherits from Django's Field class for easy integration with Django models.
- Generates a unique AztecGlyph UUID for each new model instance.
- Automatically detects ContentType.
- Automatically detects the current timestamp and resets the counter if the timestamp changes.
- One Counter per ContentType per Timestamp.
- Requires Python 3.8 or higher, Django 2.2 or higher, and AztecGlyph 1.0.0 or higher.
To use AztecGlyphField, include it in your models.py file:
from aztecglyph.extensions.django import AztecGlyphField
from django.db import models
class MyModel(models.Model):
id = AztecGlyphField(primary_key=True)
Then, use it like any other Django model field:
my_object = MyModel()
my_object.save()
print(my_object.id) # Output: 326ZtZ1QLEJ
