The name 'nodes' does not exist in the current context

Umbraco 8

Umbraco 8
Hello,

I'm re creating a website from Umbraco 7 to 8 and coming across an issue;

I'm getting the following error;

The name 'nodes' does not exist in the current context
```
 @foreach(var item in nodes.Skip((page-1)*pageSize).Take(pageSize))
    {
```
Has something changed?

Thanks

Hi Matt

This depends on what nodes is. Can you show some more code?

Hello,

This is the complete code;

@inherits Umbraco.Web.Mvc.UmbracoViewPage<ContentModels.News>
@using ContentModels = Umbraco.Web.PublishedModels;
@{
    Layout = "master.cshtml";
}


int pageSize = 3; // How many items per page
int page; // The page we are viewing

/* Set up parameters */

if (!int.TryParse(Request.QueryString["page"], out page))
{
    page = 1;
}

/* This is your basic query to select the nodes you want */

var nodes = Model.Content.Children.Where(x => x.DocumentTypeAlias == "blogItem").OrderBy("CreateDate desc");

int totalNodes = nodes.Count();
int totalPages = (int)Math.Ceiling((double)totalNodes / (double)pageSize);

/* Bounds checking */

if (page > totalPages)
{
    page = totalPages;
}
else if (page < 1)
{
    page = 1;
}

}

Thanks. There is no dynamic access to your content anymore, and some other parts have been moved around, so your var nodes line should read

var nodes = Model.Children.Where(x => x.ContentType.Alias == "blogItem").OrderByDescending(x => x.CreateDate);

Hello,

Thanks for the heads up, for some reason that line didnt want to display any content. Just a blank page.

I used the Query builder and got it working with this line;
```
var nodes = Umbraco.Content(Guid.Parse("fac06b19-ab57-40f8-bd84-ce8e97ebce96")).Children("newsItem").Where(x => x.IsVisible());
```
My understanding as well is that we cant use @item.GetPropertyValue("blogTeaser") either so I've changed it to the following @Model.Value("blogTeaser") but nothing renders.

Any help would be great, seems there are quite alot of changes in Umbraco 8

Thanks
