Introduction
PantherDB is a Simple, FileBase and Document Oriented database that you can use in your projects.
Features:
- Document Oriented
- Easy to use
- Written in pure Python +3.11 based on standard type hints
- Handle Database Encryption
Usage
Database:
-
Create a database:
db: PantherDB = PantherDB('database.pdb')
-
Create an encrypted database:
from cryptography.fernet import Fernet key = Fernet.generate_key() # Should be static (You should not generate new key on every run) db: PantherDB = PantherDB('database.pdb', secret_key=key)
-
Access to a collection:
user_collection: PantherCollection = db.collection('User')
-
Delete a collection:
db.collection('User').drop()
Create:
-
Insert document:
user: PantherDocument = db.collection('User').insert_one(first_name='Ali', last_name='Rn')
Get:
-
Find first document:
user: PantherDocument = db.collection('User').find_one(first_name='Ali', last_name='Rn')
or
user: PantherDocument = db.collection('User').find_one()
-
Find documents:
user: PantherDocument = db.collection('User').find(last_name='Rn')
-
All documents:
users: list[PantherDocument] = db.collection('User').all()
-
Count documents:
users_count: int = db.collection('User').count(first_name='Ali')
Update:
-
Update documents:
user: PantherDocument = db.collection('User').get(first_name='Ali', last_name='Rn') user.update(name='Saba')
-
Find and Update one:
_filter = {'first_name': 'Ali', 'last_name': 'Rn'} is_updated: bool = db.collection('User').update_one(_filter, first_name='Saba')
-
Filter and Update many:
_filter = {'first_name': 'Ali'} updated_count: int = db.collection('User').update_many(_filter, first_name='Saba')
Delete:
-
Delete documents:
user: PantherDocument = db.collection('User').first(first_name='Ali', last_name='Rn') user.delete()
-
Filter and Delete documents:
is_deleted: bool = db.collection('User').delete_one(first_name='Ali', last_name='Rn')
-
Filter and Delete many:
deleted_count: int = db.collection('User').delete_many(last_name='Rn')
