Question

这是我的代码，我想从存储库方法中创建API。

这是我代码的Entity表：

public partial class Course
{
    public int ID { get; set; }
    public string Name { get; set; }
    public int DepartmentID { get; set; }
    [ForeignKey("DepartmentID")]
    public virtual Department  Department { get; set; }

    public int GradeLevelsID { get; set; }
    [ForeignKey("GradeLevelsID")]
    public virtual GradeLevels GradeLevels { get; set; }

    // Navigation 
    public virtual ICollection<Units> Units { get; set; }
 }

根据方法，我需要一些输出：

为特定的年级创建课程
获取年级课程

获取课程的所有单元我在IRepository中为以下条件编写了代码

Public interface ICourseRepository
{
    Task<Course> GetAllCourseByGradeLevleId(int id)
    Task<Course> UpdateCoursetAsync(int Id);
    Task<Action> CreateCourseAsync(Course Course);
    Task<Course> DeleteCourseAsync(int Id);
}

存储库方法如下：

public class CountryRepository : ICourseRepository
{
    public Task<Action> CreateCourseAsync(Course Course)
    {
        throw new NotImplementedException();
    }

    public Task<Course> DeleteCourseAsync(int Id)
    {
        throw new NotImplementedException();
    }

    public Task<Course> GetAllCourseByGradeLevleId(int id)
    {
        throw new NotImplementedException();
    }

    public Task<Course> UpdateCoursetAsync(int Id)
    {
        throw new NotImplementedException();
    }

我的问题是我无法编写返回类型方法，也无法从关系表中获取数据，也无法针对这种情况编写POST和PUT api。

这是我的控制器类：

[Route("api/[controller]")]
    [ApiController]
    public class CourseController : ControllerBase
    {

        private readonly ICourseRepository _courseRespository;
        public CourseController(ICourseRepository courseRespository)
        {
            _courseRespository = courseRespository;
        }


        [HttpGet]
        public async Task<IEnumerable<Course>> Get()
        {
            return await _courseRespository.GetAllCourseAsync();
        }


        public async Task<ActionResult<Course>> GetId(int id)
        {
            var result = await _courseRespository.GetAllCourseByIdAsync(id);
            if (result == null)
            {
                return NotFound();
            }
            return result;
        }


        [HttpPost]
        public async Task<ActionResult> Post(Course course)
        {
            // _courseRespository.CreateCourseAsync();
            // await _courseRespository.SaveChangesAsync();
            return CreatedAtAction("GetId", new { id = course.ID }, course);
        }

在这种情况下如何编写PUT和POST。

尝试使用如下代码，

[Route("Course")]
public class CountryRepository : ICourseRepository
{
    [Route("~/users/Create")]
    [ResponseType(typeof(Course))]
    [HttpPost]
    public async Task<Action> CreateCourseAsync(Course Course)
    {
        return Request.CreateResponse(HttpStatusCode.OK, resultObj);
    }
}
