Django Redis ORM library that gives redis easy-to-use objects with fields and speeds a development up

For one project, I needed to work with redis, but redis-py provides a minimum level of work with redis. I didn't find any Django-like ORM for redis, so I wrote library python-redis-orm (PyPI) and this library is port to Django.

Working with this library, you are expected:

• Fully works in 2021
• Django-like architecture
• Easy adaptation to your needs
• Adequate informational messages and error messages
• Built-in RedisRoot class that stores specified models, with:
  • redis_instance setting - your redis connection (from redis-py)
  • prefix setting - prefix of this RedisRoot to be stored in redis
  • ignore_deserialization_errors setting - do not raise errors, while deserealizing data
  • save_consistency setting - show structure-first data
  • economy setting - to not return full data and save some requests (usually, speeds up your app on 80%)
• 10 built-in types of fields:
  • RedisField - base class for nesting
  • RedisString - string
  • RedisNumber - int or float
  • RedisId - instances IDs
  • RedisDateTime - for work with date and time, via python datetime
  • RedisForeignKey - for links to other redis models
  • RedisDjangoForeignKey - for links to other Django models
  • RedisJson - for data, that can be JSONed
  • RedisList - list
  • RedisDict - dict
• All fields supports:
  • Automatically serialization
  • Automatically deserialization
  • TTL (Time To Live) setting
  • Default values
  • Providing functions to default values
  • Allow null values setting
  • Choices
• Built-in RedisModel class, with:
  • All fields that you want
  • TTL (Time To Live), applies if no ttl on field
• CRUD (Create Read Update Delete), in our variation: save, get, filter, order, update, delete:
  • example_instance = ExampleModel(example_field='example_data').save() - to create an instance and get its data dict
  • filtered_example_instances = redis_root.get(ExampleModel, example_field='example_data') - to get all ExampleModel instances with example_field filter and get its data dict
  • ordered_instances = redis_root.order(filtered_example_instances, '-id') - to get ordered filtered_example_instances by id ('-' for reverse)
  • updated_example_instances = redis_root.update(ExampleModel, ordered_instances, example_field='another_example_data') - to update all ordered_instances example_field with value 'another_example_data' and get its data dict
  • redis_root.delete(ExampleModel, updated_example_instances) - to delete updated_example_instances

Installation

pip install django-redis-orm

Here is PyPI

Add "django_redis_orm" to your INSTALLED_APPS setting like this::

INSTALLED_APPS = [
    ...
    'django_redis_orm',
]
