What is that all about?

  1. We want to write the best code.
  2. We need the best patterns and techniques for this.
  3. We use PyAssimilator and save lots of time.
  4. We use PyAssimilator and write the best code.
  5. We use PyAssimilator and use the best patterns.
  6. We use PyAssimilator and have no dependencies in our code.
  7. We use PyAssimilator and can switch one database to another in a matter of seconds.
  8. We learn PyAssimilator once and use it forever!
  9. And most importantly, we make Python projects better!

Code comparison

Before PyAssimilator:

# BAD CODE :(

def create_user(username: str, email: str):
    # NO PATTERNS!
    # ONLY ONE DATABASE CHOICE!
    new_user = User(username=username, email=email, balance=0) # DEPENDENCY!
    session = db_session()  # DEPENDENCY!
    session.add(new_user)
    session.commit()  # NO ACID TRANSACTIONS!
    return new_user

After:

# GOOD CODE :)

def create_user(username: str, email: str, uow: UnitOfWork):
    # BEST DDD PATTERNS
    # PATTERN SUBSTITUTION/MULTIPLE DATABASES AT ONCE

    with uow:   # ACID TRANSACTIONS IN ANY DATABASE
        new_user = uow.repository.save(
            username=username,  # NO MODEL DEPENDENCIES
            email=email,
            balance=0,
        )
        uow.commit()    # AUTO ROLLBACK

    return new_user

So, do I really need it?

If you want to spend less time writing your code, but write better code - then you must use PyAssimilator. It can be hard to start if you have no experience with good code, so you can watch creator's video tutorials.

Our vision

Make Python the best programming language for enterprise development and use all of its dynamic capabilities to write things that other languages can't even comprehend!

  • Pattern substitution(switch databases easily) ✔️
  • Event-based apps(in development) 🛠️
  • 45% of all Python projects use PyAssimilator 🛠️
  • Independent code(in development) 🛠️
  • Adaptive patterns(in development) 🛠️
  • Automatic code improvements(in development) 🛠️
  • Decentralized code management(in development) 🛠️

If you want to help with any of those things - be free to contribute to the project. Remember, you never do anything for free - and that will not be the case either.

Types of patterns

These are different use cases for the patterns implemented:

  • Database - patterns for database/data layer interactions.
  • Events(in development) - projects with events or event-driven architecture.
  • Unidentified - patterns that are useful for different purposes.

Available providers

Providers are different patterns for external modules like SQLAlchemy or FastAPI.

  • Alchemy(Database, Events) - patterns for SQLAlchemy for both database and events.
  • Kafka(Events) - patterns in Kafka related to events.
  • Internal(Database, Events) - internal is the type of provider that saves everything in memory(dict, list and all the tools within your app).
  • Redis(Database, Events) - redis_ allows us to work with Redis memory database.
  • MongoDB(Database) - mongo allows us to work with MongoDB database.

py_assimilator's Issues

CRUD Service Update Issues

assimilator/core/services/crud.py", line 37, in update
obj.dict.update(update_obj.dict)

Raises an AttributeError: 'NoneType' object has no attribute 'dict'

Because:
line 33: update_obj = self.uow.repository.update() returns a 'NoneType' object that has no attribute 'dict'

Problem with SQLAlchemy 2 DeclarativeBase model imports

Problem with SQLAlchemy 2 DeclarativeBase model imports

There is a new class for DeclarativeBase models in SQLAlchemy 2. The problem is in AlchemyRepository querying. If the model import is different from the one in the Repository creation, then SQLAlchemy adds another SQL table selection to the query. That results in big overheads and possible sql errors.

Example:

SELECT * FROM users, users WHERE users.id = 1

However, the query should be:

SELECT * FROM users WHERE users.id = 1
