如何在不获取以下内容的情况下仅比较DateTime对象的时间

错误:

An exception of type 'System.NotSupportedException' occurred in mscorlib.dll but was not handled in user code Additional information: The specified type member 'TimeOfDay' is not supported in LINQ to Entities. Only initializers, entity members, and entity navigation properties are supported.

我的代码:

var date = DateTime.Parse(query.DueTime);
entities = entities.Where(r => r.DueTime.TimeOfDay.Equals(date.TimeOfDay));

这能张贴到服务器departments是null

JavaScrtipt代码:

var departments = [{ DepartmentName : "Name", DepartmentId : 1}];
Restangular.all('records/StartNewDate').post(departments);

Web Api控制器

public HttpResponseMessage StartNewDate(DepartmentViewModel[] departments)
{
  ....
  ....
}

服务器模型

public class DepartmentViewModel
{
    public int DepartmentId { get; set; }
    public string DepartmentName { get; set; }
}

我试图运行以下代码

var $ = require('gulp-load-plugins')({ lazy: true }); // fetches gulp plugins

gulp.task('wiredep', function () {
     var wiredep = require('wiredep').stream;

    return gulp
    .src(config.index)
    .pipe(wiredep(config.wiredepDefaultOptions))      //wiredep injection configuration
    .pipe($.inject(gulp.src(config.js)))              //custom js files configuation
    .pipe(gulp.dest(config.client))
});



/* inject bower and other injections */
   gulp.task('inject', ['styles-compile', 'wiredep'], function () {
     return gulp
       .src(config.index)
       .pipe($.inject(gulp.src(config.css)))
       .pipe(gulp.dest(config.client))
});

//如果我评论以下一行 .pipe($.inject(gulp.src(config.css)))

然后我的.js文件会被注入,否则他们不会,从我的理解这个注入并行发生.

我究竟做错了什么？

当它发送到MVC控制器时,如何将JavaScript字符串"5:00 PM"转换为DateTime或TimeSpan.我在用

自举timepicker

 // usage      
 <script type="text/javascript">
        $('#timepicker1').timepicker();
 </script>

Javascript负载

{
  Skip: 0
  Status: []
  Take: 15
  DueTime: "1:00 PM" // keep in mind that this is a string
}

服务器对象就像是

class TimeSheet
{
   public TimeSpan DueTime;
}

我在我的机器上安装了SQL Server Express,我只能使用SSMS连接到.\SqlExpress.如何更改它以使其成为.？

我想为SQLExpress执行此操作,这与在此处找到的答案不同" SQL Server,将命名实例转换为默认实例？ "

我ruby 2.4.2p198 (2017-09-14 revision 59899) [x86_64-darwin16]使用rbenv 安装了版本,并使用以下版本安装了railsRails 5.1.4

通过创建新的应用程序后 rails new my-app

我尝试运行时遇到了跟随错误 bundle

是否有一种更为红宝石的惯用方法来处理检查数据库是否有5条记录,然后使用if语句,是否应该在过滤器或任何类型的验证中完成？

saved_count = Model.where(is_active: true).count
if saved_count == MAX_SAVED
  return {error: 'Cannot save more than 5 records'}
end

当我尝试使用此连接字符串连接到 Mongo 实例时

mongodb://root:password@localhost:27017/

但是，当我尝试在连接字符串中指定数据库名称时，一切正常

IE mongodb://root:password@localhost:27017/storefont

我收到以下错误MongoDB Connection Error: MongoNetworkError: failed to connect to server [localhost:27017] on first connect [MongoError: Authentication failed.

示例:我不确定"部分"的含义.

section.status-dropdown
{
   /* style would go here */
}
