ADO.NET :: How To Update Domain Service From Entity Data Model

Oct 5, 2010

I'm using Entity data model to reflect my database and I generate Domain service from my Entity data model.I understand that if I have changes in my database, I can just choose "Update Model from Database", but there is no "Update Domain service from Model" option available.How should maintain my domain service? I'm not going to delete away it and regenerate it whenever there are some changes, right?

ADO.NET :: Entity Model - Update Model From DB And The Assembly Reference Seems To Be Missing?

Jan 10, 2011

I made a few changes to the DB in SQL server management studio then right clicked on the .edmx doc to get it to update. That seemed to work fine but when i compiled the app everything that referenced the EF seems to be broken.The Error list now contains the below error for all classes that used it.

The type or namespace name '' could not be found (are you missing a using directive or an assembly reference?)

Update Doesn't Work In ADO.net Entity Data Model?

Jul 10, 2010

I use ADO.net Entity Data model for work with database.

In my program, I want to update a record of user table, so I use the code below to do this.

In this function I send changed user info and then overwrite the information with the current user information.

After I run objUser = _user; and then call objContext.SaveChanges(); to save the changes.

But when I do this, the changes are not persisted to the database. I use this code for another programs but in this case the code does not work!

public void Update(tbLiUser _user)
{
LinkContext objContext = this.Context;
tbLiUser objUser = objContext.tbLiUsers.First(u => u.tluId == _user.tluId);
objContext.Attach(objUser);
objUser = _user;
objContext.SaveChanges();
}

Entity Framework 4 - Update Database Schema From Model. Without Wiping The Table Data?

Jun 29, 2010

I'm working on a new project where I have the luxury of working from a Model to Database approach using Entity Framework 4.

The project I'm working on is taking an agile approach where different phases will be rolled out over time.

Will the Model First approach work in my case? I noticed when you "Generate Database from Model" it recreates the entire schema from scratch which will obviously wipe all the data that is in the db. I was hoping for a more "Update Database from Model" approach where the db would just be altered to reflect the changes rather than recreated

Mvc Custom Model Binding In An Update Entity Scenario?

May 18, 2010

I have a question about model binding. Imagine you have an existing database entity displayed in a form and you'd like to edit some details, some properties eg createddate etc are not bound to the form, during model binding, these properties are not assigned to the model as they are not on the http post data or querystrong etc, hence their properties are null. In my controller method for update , Id just like to do

public ActionResult Update( Entity ent)
{
//Save changes to db
}

but as some properties are null in ent, they override the existing database fields which are not part of the form post data, What is the correct way to handle this? Ive tried hidden fields to hold the data, but model binding does not seem to assign hidden fields to the model.

MVC :: Using Data From Multiple Entity Framework4 Model Entity Objects In MVC2 Controller?

Sep 29, 2010

getting data from multiple Entities models into an MVC controller. Most of the examples I have seen for using EF in an MVC2 app only use a single entitiy.

I have just started using MVC2 in C# using the Entity Framework models (CIOps.model) created from an SQL database. I can create the controller and views using single tables of the model in MVC2, but I just cannot get my head around how to get data from multiple entity tables into the controller (similar to joins in T-SQL). I have included an example below of the controller code that works with a single entity table, tbl_tours (tbl_tour in DB).

Could someone please illustrate how this code would be changed to include additional columns from FK tables in addition to tbl_tours columns. E.g. the clients name from the tbl_clients, the coordinators name from the tbl_employees, and costs from tbl_costs entities? Is it possible to do this directly using the EF model entities/classes that are already created and not use LINQ, POCO, Repositories, etc.? The FK relationships are already in the EF models. I have included the whole controller code, but I just need a few examples of how to join the multiple entities, not rewrite every CRUD function function in the controller. I think this will get me over the hump in using EF in an MVC2 App. Also ignore the fact I am using the home controller, this will change in the application.

MVC :: View Model To Convert To Domain Model?

May 4, 2010

Say I got a domain model as follows: (and my repository expect an instance of this object)

[Code]....

And a view model (which my views are based on)

[Code]....

At the moment I got it like this and have my controller action manually create a new Person object from the PersonModel object before passing it on to the repository, which does not feel right.

So I tried to have PersonModel inherit from Person and pass that to the repository (also tried casting the PersonModel to a Person object first), but that don't work out.

What's the right way to have PersonModel automatically cast to Person? I want to keep this logic as my current structure allow me to keep things really loosely coupled, with the repository layer not having a clue how it's being used.

ADO.NET :: Entity Data Model - How To Use

Feb 16, 2011

I program in ASP.NET for a while now. My applications uses always the DataSet. Some told me that Entity Data Model is the DataSet for LINQ. Now I want to try to working with it I have some questions but can't find the answers. I hope someone can. When I build an application I use the 3-tier structure. So Presentation-layer, Business-layer and the Data-layer. Normally I had some classes in the Data layer with specific methods to interact with the DataSet. When I read the table or something I create an object for the business layer.

With the Entity Data Model it seems a little bit confusing. If I read a table (for example Company) the edmx has created an class already. So is the edmx a replacement for the Data-layer and also for the Business layer? Is the edmx also a good use for multi-user application or is a connected application better?

Exporting Entity Framework 4 Data Model To Entity Framework 3.5?

Oct 25, 2010

Is there a way to export a EF 4.0 Data Model to EF 3.5?

I looked around and found that we are not able to access EF 4.0 from a ASP.Net 3.5 project here: [URL]

Our project is the 1st to go to .Net 4.0 using Entity Framework and we (the team) were wondering if there was a way for the other projects that "might" need to access our data that are still using the .Net 3.5 framework.

Share Entity Data Model Amongst Layers?

May 17, 2010

How can I share the auto-generated entity data model (generated object classes) amongst all layers of my C# web app whilst only granting query access in the data layer? This uses the typical 3 layer approach: data, business, presentation.

My data layer returns an IEnumerable<T> to my business layer, but I cannot return type T to the presentation layer because I do not want the presentation layer to know of the existence of the data layer - which is where the entity framework auto-generated my classes.

It was recommended to have a seperate layer with just the data model, but I'm unsure how to seperate the data model from the query functionality the entity framework provides.

ADO.NET :: Creating An Entity Data Model Filtered On A Session Variables (C#)

Nov 1, 2010

I'm trying to customize correct displaying of dropdownlists so information shown in comboboxes is relevant to the kind of user logged on (maintaining referential integrity at data level)

e.g.: I have a user already logged on and depending on his profile I'd like to display to this user only the portion of the database that he would be allowed to see. That would mean that he might have acces to an specific subset of data, e.g.: businesstype = "3", loging level = "2", etc.

Is there a way of creating an Ado.Net Entity Data Model filtered on a Session variables as to maintain proper referential integrity at data level?
