Boris's questions

 public class User : IdentityUser<int>
 {
     public string FullName { get; set; }

     [Required]
     public int DepartmentId { get; set; }
     public Department Department { get; set; }

     [Required]
     public int PositionId { get; set; }
     public Position Position { get; set; }
 }


 public class Department
 {
     public int Id { get; set; }
     public string Name { get; set; }
     public string? UniqueNumber { get; set; }
 }

public class Position
{
    public int Id { get; set; }
    public string Title { get; set; }
}

现在，如果我删除与用户相关联的部门，该部门也会与用户或职位一起被删除。

这种情况该怎么办？如果职位或部门与用户有关联，则禁止删除，或者建立多对多关系。请告诉我解决这个问题的最佳方法。

大家好。默认颜色为“initialColor”：“#8e44ad”。是否可以做一些事情，如果数据库已经有颜色 @Model.Color !="" 那么它是从那里获取的，否则默认设置为 '#8e44ad' 视图

大家好。如何将颜色代码传递给控制器​​？我想将颜色存储在数据库中，然后以某种方式使用它，从数据库中获取指定的颜色。存储在字符串中的决定可能不太正确，如果有人告诉我更好的解决方案，我将不胜感激

大家好你们好。我正在设置sql server。但它已经有了一个基础。

文档描述了如何设置model和tempdb数据库，现在的值是：

我可以在 tempdb 中进行这些更改吗？主基地会不会有问题？主基地 500gb

Select session_id,
wait_type,
wait_duration_ms,
blocking_session_id,
resource_description,
        ResourceType = Case

            End

为什么迁移是空的？为什么没有创建字段？

第一次一切似乎都很好，然后我钝化了一些东西并删除了迁移文件夹。让我们创建新的，它们是空的

    <add name="DataContext" connectionString="Server=RDA-1; User ID=sa; Password=XNj<kz; Database = TestBase;"

Password=XNj<kz 包含字符“<”，C# 表示关闭标签。但我没有打开它。在此标记中写入密码的正确方法是什么？

大家好。请告诉我该怎么做

  <button class="login100-form-btn" id="btn">
      <!-- <a href="~/Home/Register" class="txt1">
          123
      </a>-->
      @Html.ActionLink("More information", "Register")
   </button>

页面上的按钮。我想点击按钮进入注册页面。

<script type="text/javascript">
        $(document).ready(function () {
            $('#btn').on('click', function () {
                var btn = $(this);
                btn.button('loading');
                $.ajax({
                    type: 'POST',
                    async: true,
                    cache: false,
                    url: '@Html.ActionLink("register", "Register")',
                    success: function (data) {
                        btn.button('reset');
                        $('.alert').css('display', 'block').text(data.title);
                    }
                });
            });
        });
</script>

由于某种原因，它不起作用。我一试。

<!-- <a href="~/Home/Register" class="txt1">
              123
</a>-->

这就是它的工作原理。但是你必须戳链接而不是按钮。你很容易错过。选项不太好

整个问题是这个代码一般是加载和缓存的。原件出自哪里？我找不到了。请告诉我遇到过类似情况的人如何找到要修复的正确代码。我一直在寻找一个星期，但无法弄清楚。

当您将鼠标悬停在菜单上时，它会向左或向右滑动。我想修复它，我不明白菜单样式或 Js 或 CSS 来自哪里。虽然我检查了所有的 CSS。当悬停在很远的距离时，它全部移出，结果不明白是什么。https://easy-moving.ca
