MVC :: Linq And C# Update Foreign Table

Jul 17, 2010

I have tables two tables, the "book" and the "author", a book can have many authors and vice versa, so there is an intermediate table called "book_author" with two columns as foreign key for those two primary keys

book_author
book_id
author_id

I'm trying to edit the book details and also its author using the entity date model, The controller class method

[Code]....

The HTML edit form

[Code]....

I can only update the book table, but not author that the book has or the book_author, I'm new to asp.net, I can't easily find a tutorial on this issue, I think the logic is to delete the author of the book first and then add the author for that book, but I don't know exactly about that linq and C# code. Can show me? I can only update the book table, but not author that the book has or the book_author, I'm new to asp.net, I can't easily find a tutorial on this issue, I think the logic is to delete the author of the book first and then add the author for that book, but I don't know exactly about that linq and C# code.

Select Query In LINQ Based On Foreign Table

Mar 2, 2011

I have 2 Tables , OrderDetails and Requests In my LINQ to SQL dbml file. OrderDetailsID is a foreign key in Requests Table. I want to write the query to get the sum of UnitCost from OrderDetails based on OrderId. And If there is a row in Requests Table for each OrderDetailsID, and the Requests.Last.RequestType="Refund" I want to reduce the total refund amount from the main sum otherwise If there is no row based on OrderDetailsID, add to sum. Here is the way I implement that. I am looking to prevent using "For each".

iRefund = (From od1 In dc.OrderDetails _
Where od1.OrderID =1 _
Select od1.UnitCost).Sum
Dim objOrderDetails = (From od1 In dc.OrderDetails _
Where od1.OrderID =1 _
Select od1)
For Each OrderDetail As ORM.Entities.OrderDetail In objOrderDetails
If Not OrderDetail.Requests Is Nothing Then
IF OrderDetail.Requests.Last.RequestType="Refund" Then
iRefund -= OrderDetail.UnitCost
End If
End If
Next

Add A Foreign Key From A Table In Another Database Connection?

Jan 21, 2011

I have set up a ASP.net MVC application which uses the default forms authentication. It uses the ASPNETDB.mdf like shown here:

I then set up another database connection which is similar to the NerdDinner.mdf file above.

I have a post that belongs to a user. It has a UserId value which needs to be a foreign key to the information in ASPNETDB.mdf. When I go to add a foreign key, I can only see information with regards to the table I made. How do I go about doing this?

Dynamic Data Foreign Key Table Display Name?

Nov 26, 2010

I have these two tables in my diagram:

the 1st:
PAR_TipiDocumento with
idTipoDocumento PK
idClasseDocumento
[...]

the 2nd:
PAR_ClassiDocumento with
idClasseDocumento PK
[...]

and a foreing key FK_PAR_TipiDocumento_PAR_ClassiDocumento from PAR_TipiDocumento.idClasseDocumentoto PAR_ClassiDocumento.idClasseDocumento.

This is my .cs code for the metadata:

[MetadataType(typeof(PAR_TipiDocumento_Metadata))]
[DisplayName("Tipi Documento")]
public partial class PAR_TipiDocumento[code]....

The problem is that in the Dynamic Data generated pages I correctly see all the display names "Tipi Documento" except for the header row of the PAR_ClassiDocumento table where I have "PAR_TipiDocumentos" (the plural generated by LINQ to SQL). The values under this column are correctly rendered as links to the PAR_TipiDocumento table with the right display name ("View Tipi Documento").

How can I change the Display Name of that "PAR_TipiDocumentos"?

Security :: Link Aspnet_users To Table With UserID As Foreign Key?

Aug 10, 2010

Perhaps this is a simpler VS9 question, but I want to link a SQLServer table with additional user data to the standard SQLServer membership table using the GUID userID as a foreign key. I go into design mode of my table, right-click on relationships, and click add in the dialog. but the left hand column shows me only the tables in my database. How do I get it to show the tables in the ASPNETDB.MDF database? I went through the tutorial (http://www.asp.net/learn/security/tutorial-08-cs.aspx), but it seems to magically appear in there without explanation.
