实体类型< class>不是当前上下文模型的一部分 [英] The entity type <class> is not part of the model for the current context
本文介绍了实体类型< class>不是当前上下文模型的一部分的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是一个MODEL的第一种方法。我已经进行了广泛的研究，没有提出答案。我已经尝试了以下链接中的所有建议：
这些是我已经研究的链接，所以请不要回答----
EF 4.1 Code First error - 实体类型SomeType不是当前上下文的模型的一部分
实体类型不是模型的一部分，EF 5

我已经尝试解决问题：
1）检查的数据库 - 两个查询正确返回数据。
select * from vwWorkOrderHeader
select * from vwCompanyHeader
2）从EDMX删除WorkOrderHeader，然后从数据库重新创建它。
3）取出DBContext，确保服务查询不是有趣的事情。这样可以正确地返回对象，所以这意味着它是在上下文级别或以下。
4）通过这两个测试，确保它们使用相同的方法建立上下文 - Thy do。
4）通过这两个测试，确保他们使用相同的方法来构建存储库 - Thy do。
5）唯一的区别是DatabaseContext的以下功能：
公共重载函数[ Set（T as Class）（）As System.Data.Entity.IDbSet（Of T）实现Interfaces.IDatabaseContext.Set
返回MyBase.Set（Of T）（）
结束函数
WorkOrderHeader代码在MyBase.Set（Of T）（）
{System.Data.Entity.DbSet（Of Insight.Model.WorkOrderHeader）} System.Data.Entity.DbSet（Insight.Model。 WorkOrderHeader）
CompanyHeader代码在手表中具有以下内容MyBase.Set（Of T）（）
{SELECT [Extent1]。[Name] AS [Name]，[Extent1] 。[活动] AS [活动]，[Extent1]。[创建者] AS [创建者]，[Extent1]。[创建] AS [创建]，[Extent1]。[修饰符] AS [修饰符]，[Extent1] [名称] AS [名称]，[vwCompanyHeader]。[ID] AS [ID] AS [ID] [创建者] AS [创建者]，[vwCompanyHeader]。[创建] AS [创建]，[vwCompanyHeader]。[修饰符] AS [修饰符]，[vwCompanyHeader]。[修改] AS [修改] FROM [dbo]。[vwCompanyHeader] AS [vwCompanyHeader]）AS [Extent1]} System.Data.Entity.DbSet（Insight.Model.CompanyHeader）pre>
我完全失去了这一个，进入我第三天工作同样的问题。我希望对这个问题的一些新鲜的眼睛可能会看到一个错误，我已经提出或指出我在测试我没有想到的问题的方向。
更新：
我删除了服务代码，以确保它是DBContext中的东西。我把这个服务从公式中分离出来，这样只有存储库被使用，并且都使用相同的DatabaseContext，所以它不能与连接字符串有关。我验证了在Insight_Model / EntityContainer中的模型浏览器中：Insight_Entities / Entity Sets / WorkOrderHeaders存在，InsightModel / Entity Types / WorkOrderHeader中存在。几乎看起来好像DatabaseContext甚至没有试图查询实体集的概念模型。
解决方案After 3（ 4）天（取决于你如何查看日子，我分开几天，当我睡觉，而不一定当太阳下降/出来），我找到答案。在上面的EDMX文件中，我有一个名为LeadTakenDate的列，在WorkOrderHeader类中，我使用了字段名称LeadTaken。这是我的一个愚蠢的错误。
这可能如何受益？以下是我如何解决问题：
首先，我通过MOQing部分将问题解决到一个区域，看看问题所在的兔子洞有多远。一旦我想出了DatabaseContext中的问题，我写了一个创建一个工作和非工作用例的测试用例。这样就分离了这个问题，并允许我测试理论来更快地修复它。在尝试使用EF 5.x持久性无知poco生成器之前，我尝试了一千种不同的东西。我注释掉了我在WorkOrderHeader类中的所有代码，并复制了生成的代码。重新运行我的测试，并且他们工作，所以我开始取消注释我的属性，并注释掉生成的代码，然后重新运行我的测试，直到我打到相应的属性。 p>
错误信息足够让人很难麻烦拍摄。
This is a MODEL first approach. I have already researched this extensiely and have not come up with an answer. I have tried all the suggestions at the following links:
This appears to be the same problem but with no resolution The entity type <classname> is not part of the model for the current context
These are the links I have already researched so please don't answer as duplicate of ---- EF 4.1 Code First error - The entity type SomeType is not part of the model for the current context The entity type is not part of the model, EF 5

1) Checked database - Both queries return data correctly. select * from vwWorkOrderHeader select * from vwCompanyHeader
2) Deleted WorkOrderHeader from the EDMX then recreated it from database.
3) MOQed out the DBContext to make sure that it isn't the service query doing something funny. This correctly returns the object, so it means that it is something at the context level or below.
4) Stepped through both tests to ensure that they use the same method of building the context - Thy do.
4) Stepped through both tests to ensure that they use the same method of building the repository - Thy do.
5) The only difference is during the following Function of DatabaseContext:
Public Overloads Function [Set](Of T As Class)() As System.Data.Entity.IDbSet(Of T) Implements Interfaces.IDatabaseContext.Set Return MyBase.Set(Of T)() End FunctionThe WorkOrderHeader code has the following in the watch for MyBase.Set(Of T)()
{System.Data.Entity.DbSet(Of Insight.Model.WorkOrderHeader)} System.Data.Entity.DbSet(Of Insight.Model.WorkOrderHeader)The CompanyHeader code has the following in the watch for MyBase.Set(Of T)()
{SELECT [Extent1].[Name] AS [Name], [Extent1].[Active] AS [Active], [Extent1].[Creator] AS [Creator], [Extent1].[Created] AS [Created], [Extent1].[Modifier] AS [Modifier], [Extent1].[Modified] AS [Modified], [Extent1].[ID] AS [ID] FROM (SELECT [vwCompanyHeader].[ID] AS [ID], [vwCompanyHeader].[Name] AS [Name], [vwCompanyHeader].[Active] AS [Active], [vwCompanyHeader].[Creator] AS [Creator], [vwCompanyHeader].[Created] AS [Created], [vwCompanyHeader].[Modifier] AS [Modifier], [vwCompanyHeader].[Modified] AS [Modified] FROM [dbo].[vwCompanyHeader] AS [vwCompanyHeader]) AS [Extent1]} System.Data.Entity.DbSet(Of Insight.Model.CompanyHeader)I am at a complete loss on this one and am entering my 3rd day of working on the same problem. I am hoping that some fresh eyes on the problem might see an error that I have made or point me in a direction of testing the problem that I have not thought of.
UPDATE:
I removed the service code to ensure it was something in the DBContext. I have isolated the service out of the equation so that only the repositories are being used and they are all using the same DatabaseContext, so it can't be anything related to the connection string. I verified that in the Model Browser under Insight_Model/EntityContainer:Insight_Entities/Entity Sets/WorkOrderHeaders exists and that under Insight_Model/Entity Types/WorkOrderHeader exists. It almost appears as though the DatabaseContext isn't even attempting to query the conceptual model for the entity set.
解决方案After 3 (4) days (depending on how you view days, I separate days by when I sleep and not necessarily when the sun goes down/comes up), I found the answer. In the EDMX file above, I have a column named LeadTakenDate, in the WorkOrderHeader class, I used the field name LeadTaken. This was a stupid error on my part.
How can this benefit you possibly? Here is how I resolved the problem:
First I isolated the problem to exactly one area by MOQing out parts to see how far down the rabbit hole the problem was. Once I figured out the problem was in the DatabaseContext, I wrote a test case that created a working and a non working use case. This isolated the problem and allowed me to test theories to fix it quicker. I tried a thousand different things before trying to use the EF 5.x persistance ignorant poco generator. I commented out all of my code in the WorkOrderHeader class and copied the generated code in. Reran my tests and they worked, so I started uncommenting my properties and commenting out the generated code then rerunning my test until I hit the appropriate property.
The error message is cryptic enough that is can be very difficult to trouble shoot.
