New Post: Error message in Part 8

KenBool1982 — Mon, 13 May 2013 14:10:50 GMT

I'm trying to get through part 8 of the MvcMusicStore.

I've done all the required coding but when I click the 'Add To Cart' button, I get an error message:

NullReferenceException was unhandled by user code
Object reference not set to an instance of an object.

In the debugger it's saying the error is in index.cshtml (views\shoppingCart) line 53, col 6 ch 6.

Seems to be having issues with the "@foreach (var item in Model.CartItems)

Wondering if anyone can shed anylight on the situation.. have had a look at the completed code and it's exactly the same as what's in there.

Thanks.

P.S. Error isn't in Part 10.. is in fact PART 8!!

New Post: Getting error when trying to add StoreManagerController

chickenlips — Thu, 09 May 2013 04:15:13 GMT

Hey guys, I'm experiencing a different error than everyone else. I have a feeling it has something to do with my version of SQL server installed. It basically says the following:

System.Data.Entity.Edm.EdmEntityType: : EntityType 'Album' has no key defined. Define the key for this EntityType.
System.Data.Entity.Edm.EdmEntityType: EntityType: EntitySet 'Albums' is based on type 'Album' that has no keys defined.

So did I miss a step in the tutorial somewhere?

I already tried all the other suggestions. It does seem to generate the MusicStoreDBContext connection string when trying to create the controller, even when throwing the error. So I delete the connection string and try again and get the same error as above. Any ideas?

I had a very similar issue while trying to create the StoreManagerController. The error I got was: "Unable to retrieve metadata for model object MvcMusicStore.Models.Album. Object reference not set to an instance of an object."

What I noticed is that the following line in the web.config files wasn't properly resolved:

<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

So I went ahead and re-installed the EntityFramework from the Package Manager Console by typing Install-Package EntityFramework, and that solved the problem.

Note: I was following the Music Store tutorial with MVC 4.

its work for me..
just delete <add name="MusicStoreEntities" connectionString="Data Source=|DataDirectory|MvcMusicStore.sdf" providerName="System.Data.SqlServerCe.4.0" /> or make this become a comment, and you can make StoreManagerController.

OK - I am not sure why this is, but I found a workaround for this issue and I thought I would post it for you mnlia in case you are still having trouble. Go to your web.config file and locate the following line of code that you added in one of the earlier tutorial steps: <add name="MusicStoreEntities" connectionString="Data Source=|DataDirectory|MvcMusicStore.sdf" providerName="System.Data.SqlServerCe.4.0" /> Delete it or comment it out and build the project - then create the StoreManagerController and it should work without issue. Once the controller and all the associated files have been created, then you can add your connection string back to the web.config file. I am not sure why this connection string existing is causing this error, but this will allow you to finish the tutorial.

Yes! It's works!!!

Hi.
I added the new 'add' tag but I'm having exactly the same issue. What do I need to do to fix this? Thank you.

Doesn't work for me unfortunately. After commenting out the DB Connection string, I receive the following message:

"Could not load type 'MyMusicStore.Models.Album' from assembly [...]"

Anyone else having this issue?

Also does anybody know the reasons for these two problems?

I'll just try continuing without the scaffolding...

In MvcMusicStore-Assets folder,data is another folder where data file are present.but i can not attach that data file in my database.That's why i can not use edit albums in admin section.
How can I solve this?

New Post: HTTPPost Variations

raspunkle — Sat, 30 Mar 2013 00:10:29 GMT

This due to how Method Overload works and how it is evaluated by de CLR.

public ActionResult Delete(Model id);

[HttpPost]
public ActionResult Delete(Model id);

The above is what you want to avoid. The basic rule is that when overloading, the implicit agreement is that the signatures of both need to be different from each other. For instance, by having different arguments:

public ActionResult Delete();

[HttpPost]
public ActionResult Delete(Model id);

Though, chances are that your functionality demands the same arguments. The workaround is to rename one of the methods, and annotate a custom action name. So in this case a POST request which is fired at app/controller/delete/ is actually properly interpreted by the CLR. ASP Scaffolding takes that into account and automatically appends an actionname annotation.

[HttpPost, ActionName("Delete")]
public ActionResult DeleteConfirmed(Model id)

Hi,

This context seems like a great use case to learn modern Web programming.

I'm a teacher and I'd like to create a PHP version of it, to show students the differences in implementation and similarities in concepts between the two environments.

However, I can't manage to open the completed Visual Studio solution for version 3.0b, despite having VS 2010 SP1 and ASP.NET MVC 4 installed. It may be a language problem (I'm french). I know I could follow the entire tutorial : I'll do it asap.

Is there a demo version of MVC Music Store online somewhere, so that I can at least see it in action ?

Thanks in advance for any answer. Regards,
Baptiste
