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?

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

Apr 8, 2010

I have set up Membership and Roles and can create users and login using the ASp Login control. However I need to associate users with customers (in a Customers table in the database) and display content according to the customer that the user belongs to. Is the best way of doing this to create a foreign key field in the aspnet_Users table relating back to Customers table which would have to be updated manually after creating the user or is there a better way?

DataSource Controls :: Adding New Field To A Table Mapped In LINQ?

May 25, 2010

I have a table added to a dbml file in my website. The website is already deployed to Live server. Now I have been instructed to a add a new field to the table. The field will be defaulted as getdate().

I don't plan to modify my dbml file for this change since the filed holds a default value. Will it cause any issue(performance related or any other). I am sure that I will not have to use the newly added field in the website. I am new to LINQ.

What is the best way to handle following situation? A dropdown(for master table) is optional in a particular form. But, In database table the field is constrained with foreign key. If user don't select from dropdown then It creates problem because of foreign key. One solution is to create default option in master table and use it in case of blank selection. but in dropdown, we need to handle this to show on top. Is it perfect solution?

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"?
