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?

I have a app that records some jobs and those jobs can have notes attached therefore i connected the table with a foreign key, my notes to a Job.

in the details view of the job i allow the user to view the jobs by sending the id and fulling all the notes that match the id in the index view for the notes table. in the list of notes i have a action link to create a new note, here i sent also the id of the job to the create action of the control and try to insert that intot he note JobId to make the reference. I get this error and the note is not created. the note creats from code but not via the note controller creat action.

i get this - An error occurred while updating the entries. See the inner exception for details. below is the create action in the note controller

public ActionResult Create(int id)

{
// var newnote = db.Jobs.Include("StatusNotes").Single(j => j.JobId == id);[code]...

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?

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"?

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

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.

MVC :: Creating Table Records With Foreign Key Constraints / Separate Controllers?

Oct 3, 2010

I have multiple tables that are all linked back to a central table with foreign keys. I want to be able to create a new record in table 2, but I'm having trouble because I don't know how to create a new instance of table 2's record while referencing the ID of the record it will be tied to.

EXAMPLE:

Database: Collection
Table: Collection Field 1: id Field 2: name
Table: Book Field 1: collectionId Field 2: id Field 3: name

Now, I don't want to be able to create a book without setting it's collectionID, but I can't figure out how this should be divided in the controllers/views.

Should Book have a controller separate from Collection, or should the Collection controller have a createBook method, separate from it's own create method?

I want to call the createBook method (from it's own controller, or the Collection controller) from the Collection Details view.

When I invoke the create method of Book, how do I create a new Book that is instantiated with the collectionId set from the details view of the Collection item that was listed in the details view?

I should point out, I'm using the entity framework for my model, and I'm definitely new to this.
