Decoupling Python Code: Implementing the Unit of Work and Repository Pattern |

Decoupling Python Code Implementing the Unit of Work and Repository PatternThe repository and unit of work architectural patterns are utilised to create loosely coupled abstractions between the data access and business logic layers Implementing these patterns helps insulate your application from changes facilitates automated unit testing or test driven development TDD and makes it easier to manage and maintain over time When introducing an architectural pattern a cost benefit analysis should be performed Repositories are an excellent example of this they add low level complexity but reduce high level complexity meaning each domain object will need its own repository class In return a simple interface over the data access layer is provided A concrete implementation would look something like this Concrete Implementation of the Repository and Unit of Work Architectural Patterns Repository PatternThe repository is a layer that sits between the business logic of the application and the data storage and is responsible for retrieving and storing data Every repository will have two methods add to store an object and get by id id int to retrieve a stored object by its ID I prefer to use generics since implementation logic is mostly the same and prevents code duplication Generic Repository Interface This implementation uses an Account model class with a username and password field Since Account is a domain model it requires a repository Repositories can have a variety of unique methods to query the backend For example IAccountRepository has an additional method get all to return all accounts Concrete AccountRepository Implementation The AccountRepository is loosely coupled to SQLAlchemy s Session class through the use of Dependency Injection via its constructor and inherits the IAccountRepository interface This is important because let s say a future feature requires a NoSQL backend database It can be easily implemented by passing the NoSQL database context into a repository class and implementing the interface without any change to high level modules Unit of Work PatternThe unit of work implementation is responsible for managing the changes made to a set of objects It tracks the changes made to these objects and when asked can commit or roll back the changes as a single transaction Put simply it ensures that multiple repositories share a single database context That way when a unit of work is committed all related changes will be coordinated and saved Interface for the UnitOfWork Pattern The IUnitOfWork interface provides access to the AccountsRepository through its public account attribute The enter magic method retrieves a session normally from a session factory For example SQLAlchemy has sessionmaker The exit magic method handles rolling back any changes and closing the session Concrete UnitOfWork Implementation For demonstration purposes let s assume there s a requirement to get the sum of all account balances This can be easily implemented by using the UnitOfWork class calling the AccountRepository get all method and adding each account s balance together Implement to get the Sum Of All Account Balances In summary the unit of work and repository design pattern are powerful techniques for decoupling code in Python These patterns provide a modular reusable approach to organizing code that promotes maintainability and testability and helps developers build more robust and flexible applications by separating concerns Thus these patterns are excellent choices for anyone looking to write clean decoupled and maintainable code in Python Thanks for reading You can find me on Linkedin or Github if you want to connect with me References Architecture Patterns with Python Enabling Test Driven Development Domain Driven Design and Event Driven MicroservicesImplementing the Repository and Unit of Work Patterns in an ASP NET MVC Application |

Samsung x s Galaxy Watch hits a new low of plus the rest of the week x s best tech dealsIt s a bit of a slow week for tech deals but we ve still found a handful of good prices on gadgets and gear we like For instance Samsung s Galaxy Watch our preferred smartwatch for Android users is down to a new low of while Apple s iPad Air is off its MSRP at Sony is running a sale on PS and PS exclusive games and a handful of recommended SSDs and microSD cards are down to their best prices to date Here are the best tech deals from this week that you can still get today Samsung Galaxy Watch The mm version of Samsung s Galaxy Watch is on sale for which is only about to less than its typical street price in recent months but still represents an all time low We gave the Galaxy Watch a review score of last year and it s currently the best for Android users pick in our guide to the best smartwatches Its battery life could be better but we dig its durable minimalist design crisp display and capable health tracking Samsung s One UI interface is easy enough to navigate as well and the company says it ll support the watch with software updates through PlayStation first party game saleSony has kicked off a sale on several of its own PS and PS games The discounts are available at multiple retailers including Amazon Walmart GameStop Best Buy and Sony s PlayStation Direct shop Among the highlights the racing sim Gran Turismo nbsp is down to which is above its all time low but still a discount for those looking to try out its new AI opponents or VR support The PS version is down to The PS remake of The Last of Us nbsp is off for those enjoying its TV adaptation while both the original PS remaster and the brutal sequel are available for Beyond that the lush open world game Horizon Forbidden West nbsp is down to a low of or for the PS copy which includes a free PS upgrade The friendly action game Ratchet amp Clank Rift Apart the haunting roguelike Returnal nbsp and the remade PS classic Demon s Souls are each Marvel s Spider Man Miles Morales nbsp and the remastered dual pack Uncharted Legacy of Thieves Collection are down to and both God of War and the idiosyncratic Death Stranding are available for There are more deals apart from those but either way Sony says this sale will run through March Anker ChargerAnker s Charger is a W USB C charger with a highly compact design that should be suitable for travel It only has one port but it has enough power to charge most phones tablets and even some laptops at their maximum rate The device is back down to at Amazon which is a price we ve seen a few times before but still comes in below the charger s typical going rate This deal is also available at Anker s online store but you ll need to use the code WSDOOUANO at checkout there Samsung Evo Select microSD cardSamsung s Evo Select is a U V rated microSD card that should be more than fast enough for K video on a GoPro or game storage on a Nintendo Switch or Steam Deck It s also backed by a year limited warranty The GB and GB versions of the card are still available for and respectively both of which match the lowest prices we ve tracked nbsp Samsung Pro SSDIn other Samsung storage deals the TB version of company s Pro SSD is available for an all time low of That s about below the drive s average going rate in recent months If you need more space the TB model is also on sale for a low of Not everyone needs to pay up for a high performing NVMe drive like this but for higher performing builds or expanding the storage of a PlayStation it ll work well If you do buy for a PS just make sure you pair the drive with a heatsink first You can also buy a version of this SSD with an integrated heatsink for to more depending on how much capacity you need You ll also want to make sure the SSD s firmware is up to date Various users have reported higher than usual failure rates with specific Samsung drives including the TB Pro here but the company looks to have fixed the issue with a recent update nbsp Crucial MX SSD TB You wouldn t buy a inch SATA SSD like the Crucial MX for fast storage performance on a new PC but if you re looking to upgrade an older computer that came with a slower HDD installed by default it can still provide a noticeable boost The MX itself is the top SATA pick in our guide to the best SSDs and right now its TB model is on sale for an all time low of Typically the drive retails closer to If you need more space the TB model is down to while the TB model is available for Those prices are and off the two models respective all time lows Apple iPad AirApple s iPad Air is back down to at Amazon which is more than its all time low but still roughly below its typical street price and below Apple s MSRP You should see the full discount at checkout We gave this inch tablet a review score of last year and we generally consider it the best iPad for most people While it lacks the Hz refresh rate or top end M chip of the iPad Pro it still gets you a modern design more than enough power the usual ish hours of battery life and support for Apple s best accessories all at a more affordable price nbsp Bose Portable Smart SpeakerWe highlight the aptly named Bose Portable Smart Speaker in our guide to the best portable Bluetooth speakers and right now the device is down to That s more than its all time low but still about below its typical street price and below Bose s MSRP While there are certainly cheaper options out there this wireless speaker still gets you a travel friendly IPX rated design complete with a built in carrying handle impressive bass for its size AirPlay functionality and support for both Alexa and the Google Assistant Think of it like a smaller rival to the Sonos Move Bose rates the speaker s battery life at up to hours too though that will be lower if you regularly stream over WiFi nbsp Beats Fit ProBeats rolled out a handful of new finishes for its workout friendly Fit Pro earphones this week and a couple of them ーthe coral pink and volt yellow colorways ーare already on sale for That s off Beats MSRP We ve seen prior versions of the Fit Pro drop as low as so this deal isn t an all time low but if you like the look of these colors specifically you can save a few bucks all the same The Fit Pro themselves are the best for workouts pick in our best wireless earbuds guide and earned a review score of back in late While their active noise cancellation can t match what you d get from Apple s AirPods Pro they pack many of that pair s conveniences in a sportier design Follow EngadgetDeals on Twitter and subscribe to the Engadget Deals newsletter for the latest tech deals and buying advice |
