[英]My web app doesn't find my database when published
I created a simple web app with Visual Studio 2012, using MVC3 and published it on Azure. 我使用Visual Studio 2012创建了一个简单的Web应用程序,使用MVC3并在Azure上发布。
When I run it locally, everything works fine. 当我在本地运行它时,一切正常。 But when I publish, one page where there is a table that use a db I created don't load.
但是当我发布时,一个页面中有一个使用我创建的数据库的表不会加载。 The error message is enormous, but start like this:
错误消息是巨大的,但是从这样开始:
Exception Details: System.ComponentModel.Win32Exception: The system cannot find the file specified
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Stack Trace:
[Win32Exception (0x80004005): The system cannot find the file specified]
[SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 52 - Unable to locate a Local Database Runtime installation. Verify that SQL Server Express is properly installed and that the Local Database Runtime feature is enabled.)]
System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction) +5296071
System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj, Boolean callerHasConnectionLock, Boolean asyncClose) +558
And go on and on. 然后继续。
There are three tables, one is the Default that is created by Visual Studio on its Web App sample. 有三个表,一个是Visual Studio在其Web App示例上创建的Default。 The other two I created on my own, and neither of them works when published (run perfectly fine when local).
我自己创建的另外两个,在发布时都不起作用(在本地时运行完全正常)。
I assuming the problem is on the Connection Strings, if there is anything more I should present here, please ask: 我假设问题出现在连接字符串上,如果我还有更多内容,请询问:
<connectionStrings>
<add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-Porta-comprimidos-20130503163319;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-Porta-comprimidos-20130503163319.mdf" />
<add name="RemedioDBContext"
connectionString="Data Source=|DataDirectory|\MeuPortaComprimidosDB.sdf"
providerName="System.Data.SqlClient"/>
<add name="RemedioTempDBContext"
connectionString=""
providerName="System.Data.SqlClient"/>
Can anyone, please, help me? 谁能帮帮我吗? I researched it a lot and have no idea how to handle it (yes, I am new into this).
我研究了很多,不知道如何处理它(是的,我是新手)。
Your connection strings
are settings the data source to LocalDb
which is not installed by default on Windows Azure machines and you cannot use it (unless you install it). 您的
connection strings
是将数据源设置为LocalDb
设置,默认情况下,Windows Azure计算机上未安装该数据源,您无法使用它(除非您安装它)。
You have to migrate your database to Windows Azure SQL
and change your connection string
accordingly. 您必须将数据库迁移到
Windows Azure SQL
并相应地更改connection string
。
