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


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


The HTML edit form


I can only update the book table, but not author that the book has or the book_author, I'm new to, 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?

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.


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.

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

I am trying to use the TableApapterManager.UpdateAll to insert values to master and child table. I had set the relation to cascade for update in the dataset and the HierarchicalUpdate to true. But stil when I run TableApapterManager.UpdateAll(dataset), I get a foriegn key violation error. Following is the code I used:

int ID;
DAL.Datasets.dsMembers.MembersRow rwMem = m_dsMembers.Members.NewMembersRow();
rwMem.u_name = mem.Name;
DAL.Datasets.dsMembers.MemPhonesRow rwmemphn = null;
rwmemphn = m_dsMembers.MemPhones.NewMemPhonesRow();
rwmemphn.u_memberid = ID;
rwmemphn.u_phn = "test";
return ID;

The error I get is "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_MemPhones_Members". The conflict occurred in database "Family", table "dbo.Members", column 'i_memeberid'.
The statement has been terminated."

Insert Records In My Webapp Into A Simple Sql-db-table.?

Dec 28, 2010

I need to insert records in my webapp into a simple sql-db-table. The thing is, that the user chooses the position of every new record to insert. If I take an integer index, and the user want to insert an object between the 3rd and the 4th object, it is not possible, because 3.5 is no integer-value. An index of real could be the solution. Probably a litte complicated, as soon as a new object needs to be inserted between 3.45 and 3.89 (example).

If you know an easier approach for inserting records at any position by having the ability to sort by the initially choosen order (index?)
