如何在C＃REST API中同时将数据插入两个DB

Question

当前，我有2个控制器和两个不同的表，当我使用PostMan时，它会插入到bar表中，但当我重定向它时，它不会插入到Users表中，而是要求更多的值，以便可以将该对象放置到Bars表中再次。 '

namespace UrLocal.Controllers
{

    [ApiController]
    [Route("api/[controller]")]
    public class BarsController : ControllerBase
    {
        private readonly UrLocalContext _db;

        public BarsController(UrLocalContext db)
        {
            _db = db;
        }

        // Action Methods
        // GET: api/values
        [HttpGet]
        public IActionResult GetBars()
        {
            return Ok(_db.bars.ToList());

        }


        // POST api/values
        [HttpPost]
        public async Task<IActionResult> AddBar([FromBody] Bars objBars)
        {
            if (!ModelState.IsValid)
            {
                return new JsonResult("Error While Creating New Bar");
            }
            _db.Add(objBars);
            await _db.SaveChangesAsync();

            return new JsonResult("Bar inserted successfully");
        }

        // PUT api/values/5
        [HttpPut("{id}")]
        public async Task<IActionResult> UpdateBar([FromRoute] int id, [FromBody] Bars objBars)
        {
            if (objBars ==null || id != objBars.barId)
            {
                return new JsonResult("This Bar cannot be updated");
            }
            else
            {
                _db.bars.Update(objBars);
                await _db.SaveChangesAsync();

                return new JsonResult("Bar has been updated");
            }
        }

        // DELETE api/values/5
        [HttpDelete("{id}")]
        public async Task<IActionResult> DeleteBar([FromRoute]int id)
        {
            var findBar = await _db.bars.FindAsync(id);
            if (findBar == null) return NotFound();
            else
            {
                _db.bars.Remove(findBar);
                await _db.SaveChangesAsync();

                return new JsonResult("Bar Was Removed Successfully");
            }
        }
    }
}

namespace UrLocal.Controllers
{

    [ApiController]
    [Route("api/[controller]")]
    public class UsersController : ControllerBase
    {
        private readonly UrLocalContext _db;

        public UsersController(UrLocalContext db)
        {
            _db = db;
        }

        // Action Methods
        // GET: api/values
        [HttpGet]
        public IActionResult GetUsers()
        {
            return Ok(_db.users.ToList());
        }


        // POST api/values
        [HttpPost]
        public async Task<IActionResult> AddUsers([FromBody] Users objUsers)
        {
            if (!ModelState.IsValid)
            {
                return new JsonResult("Error While Creating New User");
            }
            _db.users.Add(objUsers);
            await _db.SaveChangesAsync();

            return new JsonResult("User inserted successfully");
        }

        // PUT api/values/5
        [HttpPut("{id}")]
        public async Task<IActionResult> UpdateUser([FromRoute] int id, [FromBody] Users objUser)
        {
            if (objUser == null || id != objUser.userId)
            {
                return new JsonResult("This User cannot be updated");
            }
            else
            {
                _db.users.Update(objUser);
                await _db.SaveChangesAsync();

                return new JsonResult("User has been updated");
            }
        }

        // DELETE api/values/5
        [HttpDelete("{id}")]
        public async Task<IActionResult> DeleteUser([FromRoute]int id)
        {
            var findUser = await _db.users.FindAsync(id);
            if (findUser == null) return NotFound();
            else
            {
                _db.users.Remove(findUser);
                await _db.SaveChangesAsync();

                return new JsonResult("User Was Removed Successfully");
            }
        }
    }
}

对于我检查的问题可能是什么，我感到非常困惑，因为我正在将其输入到正确的表中，并且一切都正确，但是似乎所有这些都继续想要将值输入到bars表中。

我也知道连接是可以的，因为我可以“获取”它会返回一个空的JSON文件，但是每当我尝试发布时，它都不起作用
