Entities In 'SqlServerContext.Foos' Participate In The 'FK_Foos_Bahs' Relationship

Mar 24, 2011

I keep getting the following error message when i try to save a poco entity, using Entity Framework as the OR/M :-

Entities in 'SqlServerContext.Foos' participate in the 'FK_Foos_Bahs' relationship. 0 related 'Bah' were found. 1 'Bah' is expected.

the error message makes sense -- but that is NOT what I modeled :( (or am trying to model). It's saying that if I wish to save a Foo, then I need 1 instance of a Bah. A Foo can exist without a Bah. The relationship should be 1 <-> 0-or-1 .. not 1 <-> 1.

C# - Order A List Of Entities Based On A Field From A Separate Entity With A Relationship

Mar 6, 2011

I'm using Entity Framework for my object-relational mapping, and jqGrid for my grid.

I have an Employee entity, that contains a ContactID field. I have a Contact entity that contains fields FirstName and LastName.

I want to display a list of Employees in a grid, and give the user the ability to sort by FirstName and LastName.

Here's what I have right now:

public JsonResult GridData(string sidx, string sord, int page, int rows)
{
var pageIndex = Convert.ToInt32(page) - 1;
var pageSize = rows;
var totalRecords = GetAllEmployees().Count();
var totalPages = (int)Math.Ceiling(totalRecords / (float)pageSize);
IQueryable<Employee> employees = GetAllEmployees().
OrderBy(sidx + " " + sord).
Skip(pageIndex * pageSize).
Take(pageSize).ToArray();
}

As you can see, this only gives me the ability to sort by fields in the Employee entity, so I can't sort by FirstName and LastName.

How can I modify this to accomplish that?

ADO.NET :: EF4 Entities / Create Entities, For Instance, That Only Contains Contact Details Of Client Table?

Nov 16, 2010

I have a datamodel with a couple of tables. One of my tables have about 40 fields (I know that is a lot, but we have to keep the structure in place as we are upgrading a classic ASP project to MVC). Some of my Actions only updates 1 or 2 fields in my table.

Is there a way to create Entities, for instance, that only contains the contact details of the client table, and not any other details, and then another entity that contains only the address details. I don't want to submit the entire row when I only update telephone details, or the client's picture.

In future we want to build iphone applications and WPF applications based on the services.

Relationship Between Razor And Aspx?

Feb 26, 2011

There have been several similiar questions but I am still confused. Take the following code as example:

<% Html.RenderAction("partial"); %>

@{Html.RenderAction("partial");}

the aspx page runs well but Razor throw an error: "No route in the route table matches the supplied values." And even this is wrong, too.

Html.RenderAction("partial");

So why? What's the "@" really mean? What's the difference or relationship between aspx and cshtml?

How To Use Persistence To Maintain State / Relationship

Nov 29, 2010

I have to create a very simple database driven website ( for a project ) with basic features like a login system, etc. I have completed most of the basic tasks required, but there is one section that is asking me to 'Use persistence to maintain state/relationship'.

I have read a few articles and videos about persistence but I don't understand its benefits and why and how it should be used. Can anyone point me towards a site that explains how to implement state persistence in a simple way. I don't need anything advanced just a very simple way of integrating this into a very simple site to say its been done.

Writing To A Relationship Based Table?

Feb 15, 2010

I think I'm just after advice on best practice with this! I have a database which has 2 tables. The first table has ID, Name, Address and the second table has ID and JobType. Table 02 can list multiple types of JobType so we could have

Table01:

1. D Smith. Address01
2. S.Jones. Address02

Table02

1. Accounts
1. Sales Ledger
1. Chartered Accountant
2. IT
2. Web Design
2. Graphic Design
2. 1st line support

A join gets them together and all works perfectly.However, the content will be updated when some one fills in a web form. Do get the form to send results to both tables, I assume I have to open the database twice or can I open it once and open each table one at a time? I know I could practice this and not ask the question but I am interested to know what is the most efficient way. I would also need to know what ID to use. So when I populate Table02 it uses the correct ID from Table01. At the moment Table01 ID field is incremented automatically. Would you suggest I always assign the ID myself, or would I need to query the database, find out what ID number is currently in use and then increment it by 1 and assign the new number to an ID variable which then populates the Table's Field? In which case, am I opening the database again or trying to perform all 2/3 stages in one go?

Relationship Between Assemblies, Namespaces And Classes?

Apr 13, 2010

I'm trying to understand the relationship between assemblies, namespaces and classes. Can anyone help explain or point me to a usefule link?

1. I understand that an assembly is typicall a dll or an exe (perhaps other files also). Does each project compilation produce only 1 dll? Or is the number of DLL dictated by something completely different?

2. I read each assembly can contain multiple classes. Asingle assembly can contain classes for multiple namespaces, and asingle namespace can span multiple assemblies.

MVC :: Change Sort Order Of Relationship?

Feb 10, 2010

I have 2 tables with a relationship by EmployeeID (Employee, Cases)

The relationship name is Purchases (ie employee->Purchases), and iterating through it gives each row in order by date (entry order perhaps?).

There could be thousands of rows, so I want to present this collection in reverse date order.

Would I have to define a provider or repository to call instead of just Employee->Purchases?

SQL Reporting :: Return The Results Of A 1 To Many Relationship?

Aug 31, 2010

A co-worker of mine just came back from a SQL Server Reporting Services class (we are using SQL Server 2005). In that class they were told that if they had a one to many relationship that they would have to flatten the results into one row of the resultset in order to show the 'many' portion of the relationship. For example, my company has two tables:Jobs Notes/Memo'sor each Job we can have 0 or more Notes/Memo's.According to my co-worker the Report Server must have each of the Notes/Memo's in one row of the resultset. That we therefore have to flatten the list of Notes into Note1, Note2, Note3...etc fields.Is this correct? How would I handle a situation where I didn't know how many Notes there were?

ADO.NET :: (MS - SQL) 2 Tables - Set The Relationship One To One Via The Dmbl But Nullable?

I have 2 objects, that can exist seperately - lets say man and woman, neither needs to know about the other. But once they get get "married" it can only be married to each other. In other words, I'm trying to create 2 tables, 1 table has a FK to the other, that is NULLABLE. When i try to set the relationship to 1-to-1 via the dmbl, it wont let me - which makes sense. Ultimate i want to

Is this even possible? If i do a one-to-many - how can i make it act this way? At the business layer? create a partial class and override stuff?

Security :: Relationship Between Roles And Functionality?

Oct 18, 2010

We have an ASP.NET web application that has been around for over 4 years now. The web app uses ASP.NET role management with a custom role provider. The custom role provider connects to a database which includes tables for Users, User Groups, and Roles, with a table linking roles to user groups.

Over the years the application has grown in functionality and roles have been added. We now have around 30 roles and there is a complaint that it's not clear (due to lack of documentation, bad naming or whatever) what functionality a particular role gives a user.

Is there guidance on how to make the relationship between roles and functionality more transparent? list out the application functionality in another table and create a relationship between Role and Functionality. The application security would then be programmed against the items in the Functionality table, and the relationships between role and functionality could be maintained through a UI.

To me this approach doesn't quite fit with the concepts behind ASP.NET role based security. All the framework code methods refer to roles, e.g. "RoleProvider.IsUserInRole(string username, string roleName)" and:

<authorization>
<allow roles="members" />
</authorization>
