TChoice - Lightweight implementation of Django-like `TextChoices` and `IntegerChoices`.

TChoice

Lightweight implementation of Django-like TextChoices and IntegerChoices for Python applications.

Problem Statement

When working with FastAPI or other frameworks, it's often useful to have enumerations with labels for better readability and usability in models, forms, and APIs. While Django provides TextChoices and IntegerChoices for this purpose, they are tightly coupled to the Django framework. tchoice offers a standalone solution, allowing you to use similar functionality without requiring Django.

Installation

Install the package via pip:

pip install tchoice

How to Use

Defining Choices

You can define your choices using TextChoices or IntegerChoices:

from tchoice import TextChoices, IntegerChoices

class ColorChoices(TextChoices):
    RED = "red", "Red Color"
    GREEN = "green", "Green Color"
    BLUE = "blue", "Blue Color"

class SizeChoices(IntegerChoices):
    SMALL = 1, "Small Size"
    MEDIUM = 2, "Medium Size"
    LARGE = 3, "Large Size"

Accessing Labels and Values

print(ColorChoices.RED)          # Output: red
print(ColorChoices.RED.label)    # Output: Red Color

print(SizeChoices.SMALL)         # Output: 1
print(SizeChoices.SMALL.label)   # Output: Small Size

Using Choices in Models

For FastAPI and Pydantic:

from pydantic import BaseModel
from tchoice import TextChoices

class ColorChoices(TextChoices):
    RED = "red", "Red Color"
    GREEN = "green", "Green Color"
    BLUE = "blue", "Blue Color"

class Item(BaseModel):
    name: str
    color: ColorChoices

# Example usage
item = Item(name="Example Item", color=ColorChoices.RED)
print(item.color)           # Output: red
print(item.color.label)     # Output: Red Color
