Specification

Description

This sub package contains Gorm implementation of the database interfaces.

Structure and Organisation

Here is quick overview of the contents of this pacakge:

  • README: Current file which is aimed towards developers who wish to use and modify the database functionality.

  • generic_repository: This file implements the methods of GenericRepository interface.

  • generic_entity_repository: This file implements the methods of GenericEntityRepository interface.

  • deployment: This file contains implementation of DeploymentRequestFlat interface.

  • elk_stats: This file contains implementation of RequestTracker interface.

  • firecracker: This file contains implementation of VirtualMachine interface.

  • machine: This file contains implementation of interfaces defined in machine.go.

  • utils: This file contains utility functions with respect to Gorm implementation.

All files with *_test.go naming convention contain unit tests with respect to the specific implementation.

Functionality

GenericRepository

NewGenericRepository

  • signature: NewGenericRepository[T repositories.ModelType](db *gorm.DB) -> repositories.GenericRepository[T]

  • input: Gorm Database object

  • output: Repository of type db.gorm.GenericRepositoryGORM

NewGenericRepository function creates a new instance of GenericRepositoryGORM struct. It initializes and returns a repository with the provided GORM database.

Interface Methods

See db package readme for methods of GenericRepository interface.

GenericEntityRepository

NewGenericEntityRepository

  • signature: NewGenericEntityRepository[T repositories.ModelType](db *gorm.DB) -> repositories.GenericEntityRepository[T]

  • input #1: Gorm Database object

  • output: Repository of type db.gorm.GenericEntityRepositoryGORM

NewGenericEntityRepository creates a new instance of GenericEntityRepositoryGORM struct. It initializes and returns a repository with the provided GORM database.

Interface Methods

See db package readme for methods of GenericEntityRepository interface.

Data Types

  • db.gorm.GenericRepositoryGORM: This is a generic repository implementation using GORM as an ORM.

type GenericRepositoryGORM[T repositories.ModelType] struct {
	db *gorm.DB
}

  • db.gorm.GenericEntityRepositoryGORM: This is a generic single entity repository implementation using GORM as an ORM

type GenericEntityRepositoryGORM[T repositories.ModelType] struct {
	db *gorm.DB // db is the GORM database instance.
}

For other data types refer to db package readme.

Testing

Refer to *_test.go files for unit tests of different functionalities.
