问题描述
当实体框架接收到来自soap ui 的post 请求形式的输入时,它应该将数据记录或多条数据记录(行)插入到BdpMigrationList 表中并返回一个确认。使用 sccafold 命令将 BdpMigrationList 添加到实体。
型号:
public class BDPHMMigModel
{
public string CmNo { get; set; }
public DateTime CmDate { get; set; }
public string Ipact { get; set; }
public string Site { get; set; }
public string Version { get; set; }
public string Circuit { get; set; }
public string Customer { get; set; }
public string SourceDevice { get; set; }
public string SourceInterface { get; set; }
public string SourceInterfaceLag { get; set; }
public string DestDevice { get; set; }
public string DestInterface { get; set; }
public string DestInterfaceLag { get; set; }
public int Id { get; set; }
}
这是我的数据访问层代码:还请推荐我应该在 DAL 代码中使用哪种类类型。
public async Task<int> AddBdpHmMigData(BdpMigrationList migrationList)
{
var context = new IpReservationContext();
object newcircuit = new BdpMigrationList
{
CmNo = migrationList.CmNo,CmDate = migrationList.CmDate,Ipact = migrationList.Ipact,Site = migrationList.Site,Version = migrationList.Version,Circuit = migrationList.Circuit,Customer = migrationList.Customer,SourceDevice = migrationList.sourceDevice,SourceInterface = migrationList.sourceInterface,SourceInterfaceLag = migrationList.sourceInterfaceLag,DestDevice = migrationList.DestDevice,DestInterface = migrationList.DestInterface,DestInterfaceLag = migrationList.DestInterfaceLag
};
context.Add(newcircuit);
context.SaveChanges();
}
控制器:
[HttpPost]
public async Task<IActionResult> AddBdpHmMigData([FromBody]BDPHMMigModel model)
{
if (ModelState.IsValid)
{
try
{
var miglistID = await BdpHmDao.AddBdpHmMigData(model);
if (miglistID > 0)
{
return Ok(miglistID);
}
else
{
return NotFound();
}
}
catch (Exception)
{
return BadRequest();
}
}
return BadRequest();
实体中的 BdpMigrationList 类:
[Table("BDP_Migration_List")]
public partial class BdpMigrationList
{
[required]
[Column("CM_No")]
[StringLength(50)]
public string CmNo { get; set; }
[Column("CM_date",TypeName = "datetime")]
public DateTime CmDate { get; set; }
[Column("IPACT")]
[StringLength(50)]
public string Ipact { get; set; }
[StringLength(10)]
public string Site { get; set; }
[StringLength(10)]
public string Version { get; set; }
[required]
[StringLength(60)]
public string Circuit { get; set; }
[StringLength(150)]
public string Customer { get; set; }
[Column("Source_Device")]
[StringLength(50)]
public string SourceDevice { get; set; }
[Column("Source_Interface")]
[StringLength(50)]
public string SourceInterface { get; set; }
[Column("Source_Interface_Lag")]
[StringLength(50)]
public string SourceInterfaceLag { get; set; }
[Column("Dest_Device")]
[StringLength(50)]
public string DestDevice { get; set; }
[Column("Dest_Interface")]
[StringLength(50)]
public string DestInterface { get; set; }
[Column("Dest_Interface_Lag")]
[StringLength(50)]
public string DestInterfaceLag { get; set; }
[Key]
[Column("ID")]
public int Id { get; set; }
}
数据库上下文:
public partial class IpReservationContext : DbContext
{
public IpReservationContext()
{
}
public IpReservationContext(DbContextOptions<IpReservationContext> options)
: base(options)
{
}
public virtual DbSet<BdpMigrationList> BdpMigrationList { get; set; }
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<BdpMigrationList>(entity =>
{
entity.Property(e => e.Circuit).IsUnicode(false);
entity.Property(e => e.CmNo).IsUnicode(false);
entity.Property(e => e.Customer).IsUnicode(false);
entity.Property(e => e.DestDevice).IsUnicode(false);
entity.Property(e => e.DestInterface).IsUnicode(false);
entity.Property(e => e.DestInterfaceLag).IsUnicode(false);
entity.Property(e => e.Ipact).IsUnicode(false);
entity.Property(e => e.Site).IsUnicode(false);
entity.Property(e => e.sourceDevice).IsUnicode(false);
entity.Property(e => e.sourceInterface).IsUnicode(false);
entity.Property(e => e.sourceInterfaceLag).IsUnicode(false);
});
OnModelCreatingPartial(modelBuilder);
}
partial void OnModelCreatingPartial(ModelBuilder modelBuilder);
}
出现以下错误:
-

解决方法
试试这个代码:
修复您的控制器代码:
using ... Data Access layer name space
....
......
var bdp=new bdpHmDao();
var miglistID = await bdp.AddBdpHmMigData(model);
修复您的操作代码
public async Task<int> AddBdpHmMigData(BDPHMMigModel model)
{
using (var context = new IpReservationContext())
{
var newcircuit = BdpMigrationList
{
CmNo = model.CmNo,CmDate = model.CmDate,Ipact = model.Ipact,Site = model.Site,Version = model.Version,Circuit = model.Circuit,Customer = model.Customer,SourceDevice = model.SourceDevice,SourceInterface = model.SourceInterface,SourceInterfaceLag = model.SourceInterfaceLag,DestDevice = model.DestDevice,DestInterface = model.DestInterface,DestInterfaceLag = model.DestInterfaceLag
};
context.Set<BdpMigrationList>().Add(newcircuit);
return await context.SaveChangesAsync();
}
}
