Entity Framework 4 - Extending Context Of One Edmx File To A Context Of Another Edmx File?
Oct 14, 2010My Question is can we extend one context to another in Entity Framework 4. Following is the problem background.
I am using EF4 for developing a Web-Application. My Web Application has 3 projects.
One project is for storing candidate CV information.
Another project is for storing customer information.
Final project is called CORE. this CORE contains a edmx file that should be extended by CV and CRM.
As an example email address table can be shared by both customer (CRM) and CV. To share one table with another, we should be able to extend one context (CV context) with other context (customer context). Could some one having experience using Entity Framework share your experience with me to find whether this is possible.
We have 3 edmx files in three class libraries:
Person class library(Core) with core.edmx-Basic details related to a person(name, email) CV Class library with CV.edmx wich have CV related data(Experiance,skills) Customer Relationship management system(CRM) which have customer data(sales data...)
Then we want to use core class library edmx file(Core.edmx) with cv.edmx (basically cv tables should be able to use tables from core tables) . Same way we want to use the core.edmx with CRM.edmx for the 3 rd project
MVC :: Can Include Multiple Edmx Or Single Edmx When Designing The Model
Oct 22, 2010I recently started explore MVC and just tried some samples around, i.e. MvcMusicStore.
As the sample DB in MvcMusicStore is quite small, I am wondering how should I design the edmx/entity for a bigger database, let say for an enterprise application, which has more than 20 tables as in AdventureWorks?
Thus, the question is should I include all in one edmx/entity or I should include multiple edmx/entities when I designing the model?
C# - Difference Between .edmx File And Creating An Entities.cs File?
Mar 15, 2011I have looked at two of Microsoft's tutorials for MVC. In one tutorial they are creating a .edmx file to handle the Entity Framework in order to execute Linq queries. In another tutorial they made a class called "MusicStoreEntities.cs" here is the code:
using System.Data.Entity;
namespace MvcMusicStore.Models
{
public class MusicStoreEntities : DbContext
{
public DbSet<Album> Albums { get; set; }
public DbSet<Genre> Genres { get; set; }
public DbSet<Artist> Artists { get; set; }
public DbSet<Cart> Carts { get; set; }
public DbSet<Order> Orders { get; set; }
public DbSet<OrderDetail> OrderDetails { get; set; }
}
}
And the tutorial creates an instance of this class and starts doing Linq queries as well. What are the differences between these 2 methods? and how can I make DbSet objects in a .edmx file?
Web Forms :: Dynamic Meta Tags And Aspx Files?
Dec 8, 20101 - I am trying to create on the fly dynamic meta tags: keywords and description (possibly others later). I have managed to do so however when I view the source page I find the meta tags at the end of the Head tag and everything else is before them like reference to JS files and CSS files. I want them to be right after the title tag and then everything else is listed after them: css, js, javascript functions, etc.
2 - I am also trying to create dynamic ASPX pages. Meaning for example: I have a client who has a dynamic website that consists of 3 pages: home page, about page and contact page. He wants to add more pages to his website in the CMS software I created for him. He wants to add History.aspx page for example which is simply created using an editor (no fancy coding like gallery, products, news, etc) but when he hits the save button, I want the new page to be saved as a stand alone page and I want the navigation menu to be updated to the new links which one of them would be history.aspx. I don't want the page to be displayed as page.aspx?Id=history. I want it to have its own name. How can this be possible especially when it is not compiled and I want to add other aspx features such as the caching feature like:
<%@
OutputCache
Duration="3"
VaryByParam="none" %>=

ADO.NET :: Extend A Project With New Edmx File?
Oct 13, 2010We are using entity framework and we have two projects with two different edmx files. We need to keep both tables in same database and we want to extend funtionalities of one project by the other one. Is there a way to extend edmx files or is there a better solution for this?

View 4 RepliesHow To Specify Metadata Location In Connection String When Using An Edmx File
Jan 29, 2010I have a web project with a data model defined in an edmx file. The connection string starts like this:
metadata=res://*/;
This has worked fine for a while. But somebody else working on the project created a dll that also uses the entity framework and added it to the bin folder. Now when I try to create my connection there is an error loading the metadata.
Aside from totally changing the way one or both of us is doing things, I wonder if the problem can be fixed if my connection string can be changed to only look for the metadata defined in my edmx file. The problem is, for the life of me I can't find the right syntax to do this. The metadata is embedded in the output assembly, so there are no physical metadata files to point to. How exactly should I specify the metadata location in the connection string?
Transforming Entity Framework EDMX File With XSLT?
Aug 30, 2010I would like to make some changes to my EF4 edmx file without modifying the file itself, mainly so I don't loose all my changes if I regenerate the model from the database. I'm familiar with XSL and have seen references made to using it in conjunction with the edmx file. This sounds like a great solution, however I can't seem to find any documentation on how to actually set this up. Do you reference the style sheet from the edmx file or do you configure it to look at the template and then load the edmx file in somehow?
Clarification:
Specifically what I'm trying to do is modify the model so that several of the views act as tables with relations within the model, see here: http://blogs.msdn.com/b/alexj/archive/2009/09/01/tip-34-how-to-work-with-updatable-views.aspx
The issue I'll have in using that method is if I need to update the database and regenerate the model I'll have to go back and make all of those changes again, I was hoping there was a way to use xslt to make those changes to the views so they would not be removed when the model is regenerated.
ADO.NET :: Adding Or Removing Result Columns From Edmx File?
Nov 29, 2010I have a stroed procedure which is mapped in myEDMX file under EntityContainer >>Function Imports. When I add or remove a column from the stored procedure, I am not able to remove the old columns from the model. I right click on the stored procedure in Model browser and got to Edit Function Import. The return type is complex.
I select "get column information" and get the updated return fields but can not update the collection. It will work if I click on "Create New Complex Type" but it will generate a new name for the collection and the old collection is still in the mode. I even tried deleting and adding the stored procedures and can not get it to work. I can only edit the edmx.cs and the XML to remove it but there is got to be a better way.
ADO.NET :: Bring Back The Table Deleted From Edmx File?
Dec 29, 2010I need to add a table to a .edmx file. Earlier I had added that table, say, Table A to the edmx file. Since keys were not set, I had to delete it. Then in order to bring back the altered Table A to the file, I right clicked the file and clicked the option 'Update Model from Database'. But I couldn't find the table I deleted from the edmx file. It is there in the database. how can I bring the table back to the edmx file.
View 1 RepliesADO.NET :: Adding A New Table (entity) To The Already Created Model (edmx) File?
Mar 22, 2011I am building an application using Asp.Net 4.0 and Entity framework 4.
I have already created the model class (edmx) file using the Database-First method of the Entity framework.
Now I am almost nearning the end of the application. I have realised I need to add one more table to my database.
How do I add the newly created table to the model class (edmx) file.
If I again regenerate the model class, similar to what I did the first time i.e using the Database-First approach, will my current application be affected.
Will the already in use data like tables, relationships and views be affected in anyway.
Do I have to follow this approach everytime I need to add a new table to the entity model class.

MVC :: Get Rid Of All The Extra Code To Use Auto-scaffolding And Meta Data?
Apr 16, 2010I am using the Html.DisplayFor() and Html.EditorFor() helper methods to auto-scaffold a Display view and Edit view for a Municipality entity.
My Application layer is used to retrieve a Municipality class:
[Code]....
For the Display view this entity is mapped to a DisplayMunicipality class containing Display meta data:
[Code]....
For the Edit view this entity is mapped to an EditMunicipality class containing Edit meta data:
[Code]....
This works fine but it requires a lot of extra code, not only the code mentioned above but also all kinds of conversions inside my controller.
Is it possible to put the meta data in the Municipality class that is returned from the Application layer? In that case I need some mechanism to specify that a property should be shown in the Display view or Edit view.

View 1 RepliesSQL Server :: Any Difference With Meta Info And Binary Data In Same Table?
Dec 15, 2010I have a site where users can save images together with a couple of info fields about the image. The images are stored as binary data in the same table as the rest of the image info. So far pretty standard.
Now, the users should be able to upload a document, describing the image in more detail, along with the rest of the image and its' info.
Size ~2MB per document.
My question is: Should I store this document (binary data) in the same table as the rest of the images or should I create a new table holding only the documents. There would of course be an id reference in the image table to the document in the document table.
I have a search function joining a couple of tables, including the image table, when searching for images. I need to know if there's a difference in efficiency between these two solutions.
I always fetch the document data separately but if I don't win anything in having the documents in a separate table I'll just put it with the rest of the image info.
I'm asking this since I don't really know how SQL Server handle tables when joing and searching in them.
I have about 10´000 users with a maximum of 10 images per user. (ASP.NET - SQL Server)
(I'm not asking if I should store documents in the database, but how ;)
Example:
columns in imageTable - id, title, dateAdded, image (binary data), document (binary data)
Searching for items from a specific user I would join the userTable and the imageTable and select title where image id equals user id.
So, will there be any difference in the performance if the document is in the imageTable or in an own table?
