Umbraco 8 Root Site Logo URL issues....

Using Umbraco And Getting Started

Umbraco 8

Umbraco 8... What am I doing wrong?!?!?! The IF line works now but the lines that follow fail... I can not figure out what is happening. Everything I read says

@Model.Content.Value("pageTitle")
@Model.Content.Value<string>("pageTitle")

How do I do that from Root?

var home = Model.Content.Root(); var homePg = (HomePage)Model.Content.Root();

Neither work the only one that compiled with the IF statement was

string.IsNullOrEmpty(homePg.Value<IPublishedContent>("siteLogo").Url)

This FAILS:

string.IsNullOrEmpty(homePg.Value("siteLogo").Url)

WHY???? I still can not fix the line:

Error:

Compiler Error Message: CS1503: Argument 1: cannot convert from 'method group' to 'object'

Source Error:

Line 41: {
Line 42:     <div class="nav-link--home">
Line 43:         <img class="logo-image" src="@homePg.Value<IPublishedContent>("siteLogo").Url()"  >
Line 44:     </div>
Line 45: }

Partial Macro View:

@inherits Umbraco.Web.Macros.PartialViewMacroPage
@using Umbraco.Web

@{  
    var home = Model.Content.Root(); 
    var homePg = (HomePage)Model.Content.Root();
    var homepageSelected = @Model.Content.Id == home.Id ? " class=\"nav-link active\"" : " class=\"nav-link\"";
}

@if (homePg.Value<IPublishedContent>("siteLogo")  != null && !string.IsNullOrEmpty(homePg.Value<IPublishedContent>("siteLogo").Url))
{
    <div class="nav-link--home">
        <img class="logo-image" src="@homePg.Value<IPublishedContent>("siteLogo").Url"  >
    </div>
}

In Umbraco 8 .Content has been removed.

So your code should be:

@{ 
var homePg = Model.Root();
var homepageSelected = Model.Id == homePg.Id;
var homeNav = homepageSelected ? class=\"nav-link active\"" : " class=\"nav-link\"";
}

then

@if(homepageSelected){
 // do something if on the homepage
}

and to output the CSS class would be:

<img src="#" @homeNav />

No there is more code in the file that is just the section that errors. The homepageSelected is used in a different context.

I just realized it did not post correctly.

Here is the issue: The below line fails:

 <img class="logo-image" src="@homePg.Value<IPublishedContent>("siteLogo").Url"  >

Error: Compiler Error Message: CS1503: Argument 1: cannot convert from 'method group' to 'object'

This works however:

   @if (homePg.Value("siteLogo")  != null && !string.IsNullOrEmpty(homePg.Value<IPublishedContent>("siteLogo").Url))

I don't understand why the IF statement can use:

homePg.Value<IPublishedContent>("siteLogo").Url

And not error out but the IMG tag can not. I tryed many options for the IF statement until I finally got that working so I thought I had the solution but that solution did not fix the IMG tag. It makes no sense to me!

The siteLogo property could be of type (if allow multiple is selected)<IEnumerable<IPublishedContent>>, this is a group / list of IPublishedContent, so you need to return the first one, see below:

 var logoUrl = homePg.Value<IEnumerable<IPublishedContent>>("siteLogo").FirstOrDefault()?.Url;

The Line still errors with the SAME error:

Compiler Error Message: CS1503: Argument 1: cannot convert from 'method group' to 'object'

Line 41: {
Line 42:     <div class="nav-link--home">
Line 43:         <img class="logo-image" src="@homePg.Value<IEnumerable<IPublishedContent>>("siteLogo").FirstOrDefault()?.Url"  >
Line 44:     </div>
Line 45: }

Also what is the equivalent of:

@Model.Value("title")

To:

Model.Content.Root();

Ok, the issue is you are using a PartialViewPageMacro... which works differently to UmbracoViewPage.

@inherits Umbraco.Web.Macros.PartialViewMacroPage
@using Umbraco.Web
@using Umbraco.Web.PublishedModels
@using Umbraco.Core.Models.PublishedContent

@{
    var home = Model.Content.Root();
    var homePg = (HomePage)Model.Content.Root();
    var homepageSelected = @Model.Content.Id == home.Id ? " class=\"nav-link active\"" : " class=\"nav-link\"";
}

@if (homePg.Value<IPublishedContent>("siteLogo") != null && !string.IsNullOrEmpty(homePg.Value<IPublishedContent>("siteLogo").Url))
{
    <div class="nav-link--home">
        <img class="logo-image" src="@(homePg.Value<IPublishedContent>("siteLogo").Url)">
    </div>
}

The problem is you needed brackets around your code when you retrieve the logo url, as the razor rendering engine was assuming the first " was the close of the src.

That finally worked. Umbraco 8 is killing me I don't understand why everything is accessed different.

I think I would save years of many developers life if someone could document just one simple page:

How to access the Root OR the actual CurrentPage Model properties... i.e.

Model.Value<double>("amount")
Model.Value<IHtmlString>("bodyContent")
Model.Value("bodyContent")
Model.Content.Value<IPublishedContent>("image")
Model.Value<IEnumerable<IPublishedContent>>("sliders")

FROM each of these:

Umbraco.Web.Macros.PartialViewMacroPage
umbraco.MacroEngines.DynamicNodeContext
System.Web.Mvc.WebViewPage
Umbraco.Web.Mvc.UmbracoTemplatePage
Umbraco.Web.Mvc.UmbracoViewPage
Umbraco.Web.Mvc.UmbracoViewPage<Model>
UmbracoViewPage<dynamic>

Because they are Not the same and I can't figure out how to take a code snippet from one page type and use it in a different page type... I don't know why there is not some helper conversion for this?!?!?!?! Accessing them should be some how consistent from each type in my opinion.

If I had a mapping equivalent, for Umbraco 8 it would prevent MANY grey hairs!!! It would need to include examples of both Root as well as CurrentPage Models.

Whoever could document that would be pure genius!
