repository-pattern

问题 I'm really struggling with this & would appreciate some help please. I'm learning Android Kotlin & building an app that displays a list of walking routes (downloaded from the cloud) in a RecyclerView &, when a route is selected I want to display all details of the route - a simple Master-Detail app. Since, I'm learning I also want to try and use best practice. I have most of it working fine using a Room database & a Repository. The database is correctly populated and the RecyclerView displays

问题 I have implemented EntityFramework pattern along with Repository and Unit Of Work. The implementation is similar to Code Project Repository Example, however I need an enhancement for the Unit Of Work. The unit of work public class GenericUnitOfWork : IDisposable { // Initialization code public Dictionary<Type, object> repositories = new Dictionary<Type, object>(); public IRepository<T> Repository<T>() where T : class { if (repositories.Keys.Contains(typeof(T)) == true) { return repositories

问题 I have a sample project in which I experiment with different technologies. I have the following setup: Spring Boot 2.3.4.RELEASE Flyway 7.0.1 Testcontainers 1.15.0-rc2 Junit 5.7.0 How can I test the Repository layer with testcontainer-junit5? Example of code I have now for CompanyRepositoryTest.java : @ExtendWith(SpringExtension.class) @Testcontainers public class CompanyRepositoryTest { @Autowired private CompanyRepository companyRepository; @Container public MySQLContainer mysqlContainer =

问题 Take this simple, contrived example: UserRepository.GetAllUsers(); UserRepository.GetUserById(); Inevitably, I will have more complex "queries", such as: //returns users where active=true, deleted=false, and confirmed = true GetActiveUsers(); I'm having trouble determining where the responsibility of the repository ends. GetActiveUsers() represents a simple "query". Does it belong in the repository ? How about something that involves a bit of logic, such as: //activate the user, set the

Improve this question I have created a simple Web API that interfaces with a MySQL Database. I am old school and like using SqlConnection/SqlCommand classes to interact with the database, no ORM/no EF. I have created a MySQL DbContext so that I can use DI to inject the MySQL specifics and

问题 I recently got aware of repository pattern. I am quite new to this pattern and tried to shift my code in this patter. I am using Node js and Sequelize ORM with Sqlite database. Following route is working router.get('/listquestions',(req,res)=>{ Question.findAll({ attributes: ['id','title'], include: [{ model:Lecture, attributes: ['id','videoname','coursecode'], }] }).then((questions) => { if(questions){ console.log(JSON.stringify(questions)); res.render('pages/questionslist', {data:questions}
