列名无效。不知道为什么？

Question

最近我将DateofBirth添加到表中。在本地，它的工作正常。我还更新了客户端的数据库和实体数据模型。但是出现了错误。

列名称“DateofBirth”无效。描述：执行当前Web请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。

异常详细信息：System.Data.SqlClient.SqlException：无效的列名称'DateofBirth'。

Answer 1

该列不存在于表中，您必须运行迁移或使用其他方法更新客户数据库

Answer 2

基于堆栈跟踪，我怀疑您已在配置类中将AutomaticMigrationsEnabled设置为false。要解决此问题，您需要手动创建新的迁移文件。您可以在Nuget包管理器控制台中创建运行Add-Migration命令的新迁移。

Here is a tutorial on how to create a new migration script.
