在 Devart 实体框架中添加视图之间的关系

发布于 2025-01-07 10:18:41 字数 715 浏览 0 评论 0原文

我想在 EF 中的视图之间建立关系。我正在按照这篇文章在 xml 文件中修改它。 http://smehrozalam.wordpress.com/2009/08/12/entity-framework-creating-a-model-using-views-instead-of-tables/。

我收到错误，

Custom tool error: Multiplicity is not valid in Role 'VIEW' in relationship 'FK_'. Because the Dependent Role refers to the key properties, the upper bound of the multiplicity of the Dependent Role must be 1.

我不确定我是否走在正确的道路上。

这样做的主要目标是通过 oData 使用该实体，并链接到视图中的 Id。我没有直接使用这些表，因为该表有 ID，我希望将名称发送回客户端。这种关系应该向孩子提供详细信息。

如果还有其他方法可以实现这一点，请帮忙！！

提前致谢

I want to have a relation between views in EF. I am following this post to modify it in the xml file.

I am getting error,

Custom tool error: Multiplicity is not valid in Role 'VIEW' in relationship 'FK_'. Because the Dependent Role refers to the key properties, the upper bound of the multiplicity of the Dependent Role must be 1.

I am not really sure if I am going the right path.

The main goal of doing this is to use this entity over oData, and have links to the Ids in the view. I am not using the tables directly, because the table has Ids and I want the names to be sent back to the client. The relationship should give the child details.

If there is any other way to achieve this, please help!!

Thanks in Advance
