Django Chunked Field

This project provides a custom Django field, ChunkedTextField, designed to handle large text data by splitting it into manageable chunks for storage in a separate database table. Unlike traditional text fields, which may face size limitations in certain database systems, ChunkedTextField bypasses these constraints while seamlessly integrating with Django's ORM. It works transparently with serializers, admin interfaces, and other ORM features, allowing developers to store and retrieve large text data without changing their application logic. The field is particularly useful in applications requiring efficient management of text data exceeding database limits, ensuring scalability and ease of use.

Features

• Store large text data exceeding database field size limits.
• Seamlessly integrates with Django's admin and ORM.
• Customizable truncation for admin display.

Installation

1. Install the package using pip:

   pip install django-chunked-field
   

2. Add chunked_field to your INSTALLED_APPS in your Django settings:

   INSTALLED_APPS = [
       ...
       'chunked_field',
   ]
   

3. Run the migrations to create the necessary database tables:

   python manage.py migrate
   

Usage

Defining a Model

To use the ChunkedTextField, define it in your model as follows:

from django.db import models
from chunked_field.fields import ChunkedTextField


class MyModel(models.Model):
   large_text = ChunkedTextField(truncate_length=100, chunk_size=4000)

Admin Integration

To display the DataChunk model in the Django admin, register it in admin.py:

from django.contrib import admin
from chunked_field.models import DataChunk


@admin.register(DataChunk)
class DataChunkAdmin(admin.ModelAdmin):
   list_display = ('content_type', 'object_id', 'field_name', 'sequence')
   list_filter = ('content_type', 'field_name')
   search_fields = ('content',)

Signal Handlers

The ChunkedTextField automatically handles the chunking and reassembly of data using Django signals. You do not need to manually manage these operations.
