DeleteByIdAsync(dynamic id) 问题 返回
liftlei 发布于2020/12/18
使用SimpleClient 的 DeleteByIdAsync(dynamic id)时发生以下错误：
System.AggregateException: One or more errors occurred. ('int' does not contain a definition for 'GetAwaiter')
---> Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'int' does not contain a definition for 'GetAwaiter'
at CallSite.Target(Closure , CallSite , Object )
at System.Dynamic.UpdateDelegates.UpdateAndExecute1[T0,TRet](CallSite site, T0 arg0)
at SqlSugar.SimpleClient`1.DeleteByIdAsync(Object id)
--- End of inner exception stack trace ---
at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions)
at System.Threading.Tasks.Task`1.GetResultCore(Boolean waitCompletionNotification)
at System.Threading.Tasks.Task`1.get_Result()
源码如下：
[HttpPost, Route("delete")]
public async Task<IActionResult> Delete([FromForm] string id)
{
if (string.IsNullOrEmpty(id))
{
return Fail("ID 不能为空");
}
return Result(await _printTemplateService.DeleteByIdAsync(id));
}

2020/12/18看一下initkey是不是配置的attribute，在看一下实体是不是配有主键

SimpleClient.DeleteByIdAsync 这个方法确实有问题你先用
public virtual async Task<bool> DeleteByIdsAsync(dynamic[] ids) 先用这个代替

@fate stay night：大佬，都没错
=============================
var config = new ConnectionConfig()
{
ConnectionString = _options.DefaultConnection,
DbType = dbType,
IsAutoCloseConnection = true,
ConfigureExternalServices = new ConfigureExternalServices()
{
DataInfoCacheService = cacheService
},
MoreSettings = new ConnMoreSettings()
{
IsAutoRemoveDataCache = true,
DefaultCacheDurationInSeconds = 1800
},
InitKeyType = InitKeyType.Attribute
};
====================================
[SugarTable("print_template")]
public class PrintTemplate
{
[SugarColumn(IsPrimaryKey = true, IsIdentity = true)]
public int Id { get; set; }

现在改成这样用：
[HttpPost, Route("delete")]
public async Task<IActionResult> Delete(PrintTemplate model)
{
if (model == null)
{
return Fail("参数不能为空");
}
return Result(await _printTemplateService.DeleteAsync(model));
}
