Commented Issue: error using audit tracking -conn string not set. [8714]

giannik — Wed, 01 May 2013 19:21:08 GMT

Hello,
I'm using the modules feature and enabled ''Allow audit tracking'' to audit changes on records.

I am using this code to get the audit records of a model instanse

```
const string cnnstr = @"metadata=~\Modules\company.data.Sys.EFDAL\Data.csdl|~\Modules\company.data.Sys.EFDAL\Data.ssdl|~\Modules\company.data.Sys.EFDAL\Data.msl;provider=System.Data.SqlClient;provider connection string='server = 127.0.0.1,1433\sqlexpress;database = companydata;uid = sa;pwd = 123'";

var startup = new ContextStartup("sa");

using (var db = new company.data.Module1.EFDAL.dataEntities(startup, cnnstr))
{
var record = db.ChildItem.FirstOrDefault();

if (record != null)
{
var auditrecs= record.GetAuditRecords().ToList();
}
}
```

As you can see i am passing in the connection string directly to the db context.

When it gets to line : record.GetAuditRecords() an error is caused :''Null reference object'' and i cannot get the audit records.
I've pinpointed the problem at this line of code :

```
var s = System.Configuration.ConfigurationManager.ConnectionStrings["dataEntities"].ConnectionString;
```

inside file : company.data.Module1.EFDAL\dataEntities.Generated.cs.

It seems that it is assuming connection string will be in the config file (which it isnot because i am passing it by code) and since it doesnt find it it blows.

Could'nt find a way to get around it. I think that the audit record classes need to be aware of the db context that is calling them in order to use the same connection string.

Hope this can be fixed as this is one of the best features of nhydrate , for me.

see attached model file for example

Thanks

This will be addressed in the next version in that an instance will read the connection string of its parent context. Also the context will have ConnectionString property. And finally the static audit methods will have an overload to pass in a connection string.

Commented Issue: Unhandled exception in GetPagedResults [8649]

codetools — Mon, 25 Mar 2013 15:21:22 GMT

I think that some form of error handling for EntityException in item.Count() may be needed here:

```
public static IEnumerable<T> GetPagedResults<TKey>(
this System.Data.Objects.ObjectSet<T> item,
System.Linq.Expressions.Expression<Func<T, bool>> where,
System.Linq.Expressions.Expression<Func<T, TKey>> orderBy,
bool orderAscending,
nHydrate.EFCore.DataAccess.Paging paging)
{
var index = paging.PageIndex;
var rpp = paging.RecordsperPage;
if (index < 1) index = 1;
if (rpp < 1) rpp = 1;

paging.RecordCount = item.Count(where);
paging.PageCount = paging.RecordCount / rpp;
if ((paging.RecordCount % rpp) != 0) paging.PageCount++;

var q = item.Where(where);

if (orderAscending)
q = q.OrderBy(orderBy);
else
q = q.OrderByDescending(orderBy);

return q.Skip((index - 1) * rpp)
.Take(rpp)
.ToList();

}
```

Would you please post the error your received? This might help me with this issue.

Created Issue: Possible problem with inherited entities in ORMMap [8614]

betaphreak — Fri, 08 Mar 2013 15:25:06 GMT

Based on your AcmeSales sample I have been writing some ASP.NET stuff by hand. Everything's nice and smooth until I get to the following situation where the DataBind() method in ORMMap.cs triggers the following code in one of the .Generated.cs from the Item.aspx of an entity that has others inheriting from it.

```
object nHydrate.EFCore.DataAccess.IReadOnlyBusinessObject.GetValue(System.Enum field, object defaultValue)
{
if (field.GetType() != typeof(FieldNameConstants))
throw new Exception("The '" + field.GetType().ReflectedType.ToString() + ".FieldNameConstants' value is not valid. The field parameter must be of type '" + this.GetType().ToString() + ".FieldNameConstants'.");
return this.GetValue((FieldNameConstants)field, defaultValue);
}

```
It seems the FieldNameConstants of the base entity is not ok here and it should be the one in the entity that inherits from this. I don't understand why its implemented this way since I am browsing the details of the base entity.

Is this intentional?

Best regards

Closed Issue: Issue with VS2012 installed breaking VS2010 [8409]

codetools — Sat, 16 Feb 2013 15:16:01 GMT

Woe is me.

I was working happily with VS2010 Pro (SP1) running my project with an nHydrate model in it. So I thought it would be good to install VS2012 Pro on my development PC.

However, no code changes after installing VS2012, I fired up the VS2010 project in VS2010. When it tries to open the connection, I get the following stack trace:

System.Data.MappingException occurred
HResult=-2146232032
Message=Schema specified is not valid. Errors:

Clearly VS2012 has done some patching with Entity Framework. I though these could live side by side.

I have tried resetting my devstudio settings with devenv /resetsettings which didn't work. Next I tried re-applying SP1. Which also didn't work.

Not too sure what to do next. I think I'm gonna uninstall VS2012 - drastic measures.

Anyone had this issue?

When you install VS 2012 it installer EF 4.1. There is a big issue with this in one condition. If you have a stored procedure with no fields (return) EF blows up. I see your proc returns a result. Please ensure that your model has at least one defined field in the model stored procedure object.

It is the latest version I am using.

1. I've installed VS2012 on a clean Windows 8 Pro N 64-bit install with SQL 2012 Enterprise.
2. I've downloaded nHydrate and installed the February release (5.1.2.117).
3. I've removed the references to the old nHydrate files in my solution and added new nHydrate.EFCore.dll.
4. I backed up and restored the database from my Windows 7 install to Windows 8.

I am getting exactly the same exception as I first mentioned.

I am unsure if it may be the actual stored procedure. Here is the content from SQL Server:

```
USE [WMS_UAT]
GO
/****** Object: StoredProcedure [dbo].[up_GetNextUniqueReportNumber] Script Date: 12/02/2013 22:38:59 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[up_GetNextUniqueReportNumber]
(
@contract_id int = null,
@type varchar(10) = null
)
AS

BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

DECLARE @Result INT

-- either insert or update depending upon type (inpsection/repair)
IF EXISTS(SELECT * FROM [dbo].[unique_report_number] WHERE [contract_id] = @contract_id AND [type] = @type)
BEGIN
UPDATE [dbo].[unique_report_number] WITH (ROWLOCK, UPDLOCK)
SET @Result = [unique_number] = [unique_number] + 1
WHERE [contract_id] = @contract_id AND [type] = @type
END
ELSE
BEGIN
INSERT INTO [dbo].[unique_report_number]
([contract_id]
,[type]
,[unique_number])
VALUES
(@contract_id
,@type
,1)

-- first row, so unique number is 1
SET @Result = 1
END

-- all done so return result
RETURN @Result

END

```

I sorted my new issue out. Had to create a new nHydrate diagram, import database, then manually edit the new .nhydrate and .diagram files.

.nhydrate - copy and replace the entities, storedProcedure, and relationFields nodes from the old file to the new. Change the GUID for nHydrateModel Id to the same in the old file.

.diagram - copy and replace nestedChildShapes node from the old file to the new. Change nHydrateModelMoniker Id to the GUID in the old file.

Hi Chris,

Will try and get round to putting VS2012 alongside VS2010 again on Windows 7. Still working solely on 2010 with the 5+ line. I've got 2012 on a separate partition on Windows 8 but under pressure at minute as I am mid project on things. Will try and keep you posted.

However, I just installed Febuary 3rd release and I can't open my existing model now. Will investigate this further. I did have to uninstall November release first from Programs and Features.

Cheers,

Andez

Please tell me are you using nHydrate 4.1 or the 5+ line? There is an issue with the old 4.1 line if the .NET framework 4.5 is installed. This is not an issue using the 5+ line. Would you send some more information? If you have specific data or information to send you can reach me at chrisd@nhydrate.org.

Closed Issue: VS2012 support? [8328]

codetools — Wed, 06 Feb 2013 02:48:03 GMT

Hi,

I installed a new machine with Windows 7, Visual Studio 2012 Ultimate and nHydrate version 5.1.2.112.
When I try to add a new item to a project the nHydrate model template does not appear.
When I open an old VS2010 project and I doubleclick the .nhydrate file in the solution explorer it opens in the XML editor.

I also tried on a machine with Windows 8, Visual Studio 2012 and nHydrate version 5.1.2.112 with the same result. In VS2010 everything worked fine.

Do I have to take extra steps to make it work in VS2012?

Thx,

Jan.

Closed Issue: Default value of column improperly applied to entity constructor. [8536]

codetools — Sat, 02 Feb 2013 14:02:04 GMT

We have a number of default values in our existing database that use the 'newsequentialid' function. When importing those tables, the 'newsequentialid' value is set as the default value of the field. When EF code is generated, an improper constructor is created that sets the private member _guid to an invalid value:

ctor()
_guid = new Guid("newsequentialid")

Here's a script that sets the default constraint on a field in my table:
ALTER TABLE [dbo].[mytable] ADD CONSTRAINT [DF_MyTable_Guid] DEFAULT (newsequentialid()) FOR [Guid]

As a workaround, I've modified my model XML file(s) to replace the 'default="newsequentialid"' string with 'default=""' to remove the default altogether.
Comments: This functionality will be in the next version.

codetools — Sat, 02 Feb 2013 14:01:08 GMT

This functionality will be in the next version. The SQL keyword 'newsequentialid' will be supported as a default and generated properly as well as imported from an existing database. Please look for this in the next release.

Commented Issue: views and stored procs in models does not work when enabling modules [8475]

giannik — Sat, 29 Dec 2012 08:24:02 GMT

I have attached a sample project (in vs 2010) which uses modules feature and creates a view and stored proc model.
When i try to execute the view and stored proc model from a client app i get these errors :
For view : {"Invalid object name 'dbo.OperationExt'."}
for stored proc : {"Could not find stored procedure 'dbo.OperationExtSp'."}
I suspect the same might happen for function models but i have'nt tried it out.
Thanks
