I need to know is there any way to separate the classes automatically created by Entity framework. I can not use POCO template. because I have restriction to use framework 4.0 for time being.
I am having VS 2008 Framework 3.5
Do I have any service packs which gives me POCO.
I have this small piece of code
var idObjects = Spring.Context.Support.ContextRegistry.GetContext()
.GetObjectsOfType(typeof (ICustomInterfaceThatDoesSomething));
foreach (ICustomInterfaceThatDoesSomething icitds in idObjects.Values)
icitds.DoSomething();
Is there a way i can avoid this by having spring.net automatically inject the singletons to a property i declare, like an array of ICustomInterfaceThatDoesSomething?
The only reason i want something like this is because i want to kill the .dll dependency on the project and this is the single point of usage.

View 5 RepliesI am using EF4 with POCO entities and having problems to update an existing item. In a webbapp I have an ajax function fetching an entity object from the database through EF4. Then i make some changes to it and when I try to update the record in the database I call the Attach-method but it is not saved. I guess this has something do with that I am not in the same context anymore...so my question is how to make an update of a previously fetched record if the context which was used to fetch record is disposed?

View 2 RepliesAnyone know of a simple tool to quickly create POCO classes based on an existing database?
I am just looking to create the POCO classes that could be used with any ORM that supports it so my interface and model can remain independent.
I have an interesting problem with a WCF Service I am creating. As background fodder my solultion uses MVC 3 RC2 as the web interface. I am developing the solution as an N-Tier application using the Entity Framework 4.0 with POCO Self Tracking Entities, repository and unit of work approach. I am using the STE's more as an advanced POCO since STE do not seem to play well as of yet in the real world as they were meant to and since they do seem to give me better interfacing with the DB through my layers still. Additionally, I am incorporating WCF into the solution as the backend for the models based on info I am reading and the fact that I will need to also access these services via a windows service app on the client computers.
So, I have a datastore which includes my edm and the repositories. The POCO STEs are generated in a separate layer in what I have called my Domain Models. Within my domain area I also have a Core app holding my utilities. I am currently incorporating an additional domain element as a WCF service using the RESTful template. This WCF will be servicing both my MVC controllers and a Windows Service app on the client computers.
Now, on to the problem: Within this solution I have an Entity Set of People (or Person?). Within that Entity set I have a chain of inherited entities as follows Person->User->StaffMember->Provider where Provider is the resultant child. Within my WCF I have a ProviderService, a StaffMemberService and a UserService. In each of these Services one of my OperationContracts is a Get(string id) amongst others. the Get(String id) contract is the one that is causing me problems. Within that Get(String id) contract I do the following for the User:
[Code]....
and for the Provider:
[Code]....
Now, what has gotten me completely confused is that the Provider one works like a charm. But if I use the UserService to call the User of the same Id (Since User is a base class for Provider, this should work) I get an error saying it was a bad service call. (The ProviderService, as stated works and returns all the correct data). When I debug it, the UserService Get(String id) function actually works as expected up to and through the return statement (ie the user variable actually contains all the proper data that I would expect on the call). It is only after the return that I get the web page giving me that error and points me to the help page for the service. (I am using the browser to view the results at this point only). </P><P>I am assuming it has something to do with serialization? But why is it displaying the derived class with all expected data, which yes does include the data not being displayed as a user data, I am calling the data using the same UserId. I am not expecting someone to inspect my code, but to be a traffic cop and point me in the direction I need to look.
I have POCO's in a separate project and now I need Self Tracking Entities. Does anyone know if I need to generate new POCO's that are self tracking and they will replace my current POCO's? Or, do I setup self tracking entities in addition to my current POCO's?

View 1 RepliesI do need a working ASP.NET C# code to replace characters in a string.
My following code works fine but in case of input "a" it gives me an output as "678d", but in case of input "c" the output is correct as it is i.e. "8d"... Here it automatically replaces the rest values too. I can see the code is executing in a step by step process... This results me to get an overloaded output.
{
StringBuilder builder = new StringBuilder();
builder.Replace("a", "6b");
builder.Replace("b", "7c");
builder.Replace("c", "8d");
return builder.ToString();
}
Now, I do need to replace "a" as just "6b" and it should not load the rest values.
I am looking for a solid tutorial on using the Entity Framework with POCO (ie. not using the designer) using MySQL as the back-end. I am looking for something that is semi-in-depth covering stuff like attributes (like how to map a database table/field name to a class/field name that is different). Also I am looking for C#, not VB. Does anyone know of any such tutorials?

Currently im using EF and using its datacontext directly in all of my actions, but since i started reading about loose coupling and testability im thinking that thats not the best way to go. Im trying to understand all the pro's and con's before i start refactor all my current code.
Problem 1:
Considering that every entity needs its own repository, and thus has to setup its own connection to a datasource (lets assume a database using EF), wouldnt that give alot of overhead if i need data from 5 different entities on a single page?
Problem 2:
What im seeing aswell in all the examples which i found online is that most people (even people like shanselman) implement the repository pattern using the entity classes which are generated by either LINQ or EF, doesn't this defeat the purpose of repository pattern with regards to loose coupling? On the other hand, what is the alternative, using POCO classes in combination with for example AutoMapper? (this scares me a little) Im hoping that a few people can shed some light on this, because im a bit confused at the moment if the repository pattern is the right choice for a website.
I am doing some url redirections in a project that I am currently working on. I am new to web development and was wondering what the best practise was to remove any illegal path characters, such as ' ? etc.I'm hoping I don't have to resort to manually replacing each character with their encoded urls.I have tried UrlEncode and HTMLEncode, but UrlEncode doesn't cater for the ? and HTMLEncode doesn't cater for 'E.G. If I was to use the following:
Dim name As String = "Dave's gone, why?"
Dim url As String = String.Format("~/books/{0}/{1}/default.aspx", bookID, name)
Response.Redirect(url)
I've tried wrapping url like this:Dim encodedUrl As String = Server.UrlEncode(url)AndDim encodedUrl As String = Server.HTMLEncode(url)

View 1 RepliesI want to prompt the user before allowing them to save a record. So let's assume I have the following button defined in the markup:
<asp:Button ID="btnSave" runat="server" OnClick="btnSave_Click"></asp:Button>
To force a prompt with normal javascript, I could wire the OnClick event for my save button to be something like this (I could do this in Page_Load):
btnSave.Attributes.Add("onclick",
"return confirm('are you sure you want to save?');");
The confirm call will block until the user actually presses on of the Yes/No buttons, which is the behavior I want. If the user presses 'Yes', then my btnSave_OnClick method would be called.
For the jquery dialog that is the equivalent, I tried something like this (see below). But the problem is that unlike javascript confirm(), it's going to get all the way through this function (displayYesNoAlert) and then proceed into my btnSave_OnClick method on the C# side. I need a way to make it "block", until the user presses the Yes or No button, and then return true or false so the btnSave_OnClick will be called or not called depending on the user's answer.
Currently, I just gave up and went with javascript's confirm, I just wondered if there was a way to do it.
[code]...
I'm a new user of ASP.NET MVC and I'm trying to replicate the ListView control from WebForms in an AJAX-y manner. Take the following as an example:
[Code]....
The "ItemTemplate", "EditItemTemplate", and "InsertItemTemplate" replacements are implemented as Partial Views, so the view for this page looks something like this:
[Code]....
The edit/update flow is very simple. The user clicks the "edit" button, an AJAX request is made to get the "EditItemTemplate", and the contents of that row are replaced with the "EditItemTemplate". When the user clicks "Update" in the edit row, the form is submitted via AJAX and the resulting content replaces the "EditItemTemplate".
The part I'm not sure how to deal with is the InsertItemTemplate. When the user submits the insert form, I need two partial views to be returned: one to replace the InsertItemTemplate (clear the form or show any validation errors), and one to insert into the table as a new record (ItemTemplate). I'm not sure what to do about this...the only options I've come up with are:
Make 2 Ajax requests -- one to insert the item and get the ItemTemplate for the new item and another to get a clean InsertItemTemplate Make 1 Ajax request for JSON -- render the ItemTemplate and InsertItemTemplates into strings and then put them into a JSON object that can be analyzed client-side (ex: { itemtemplate: "<tr>...</tr>", insertitemtemplate: "<tr>...</tr>" }) Make 1 Ajax request for the ItemTemplate and then manually clear the InsertItemTemplate form client-side (removing any form entries and validation elements)
None of these options really seem that great to me...especially #1 (because of a second AJAX request) and #3 (because it keeps my solution from being easily reused on other "ListView replacements" due to the need to manually clear the form). #2 is somewhat acceptable but still kind of hacky because rendering partial views to strings and then sending them in JSON isn't easy to do and ends up being a bit of a hack.
Is there a way to effectively have two "browsers" on one page without using framesets?My wording may be a bit confusing there, so here is what I'm trying to achieve...Let's say I have a web page that has an asp:textbox and an asp:button. The user types any URL they want (let's usewww.asp.net as an example) into the text box and clicks the button.I then want to load that URL (www.asp.net) into a control, or something, on the page so that I can show that page's content (I do not want to load it into a separate page or replace the current page). I want to specify the placement and size of the control on my page. I also want to be able to access the page source of the content that's been loaded into the control from my code-behind.I know that "some" of this can be achieved using framesets but not all, and as I understand it, framesets are on the way out and I shouldn't use them anyway.
View 7 RepliesI was wondering if anyone can point me in the right direction? I have a POCO model and I am using Code First CTP. In my application, I set the database to be recreated whenever the model changes.
I would like to write custom functionality to access the model (POCO) metadata same way as EF sees it and use that to generate some source files (using T4). I would like to access the processed model not having to worry about finding properties that hold primary keys or any other conventions (implicit or not). What is the way to go about it?
I want to put POCO object to Velocity cache. How can I serializable ICollection to Velocity cache, or exclude ICollection from serialization?
I got this exception
Type 'System.Collections.Generic.ICollection`1[Model.Collection]' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute. See the Microsoft .NET Framework documentation for other supported types.
