I'm not sure that qualifies as an answer to the question? Even creating a property with a different name in this scenario wouldn't result in the issue OP has being resolved. It seems he even wrote:

If I rename the property to something else, for example: FindMetaDescription, I can't seem to reach that property in my view via @Model.GetProperty("findMetaDescription").

So renaming won't work.

I missed that part ;)

Hi,

It seems you are trying to invoke the properties as if they are value on the published content. They are not, they are properties created in your code, and need to be called like Model.[Property], in this case @Model.FindMetaDescription() or @Model.MetaDescription depending on what you implement.

HTH :)

Hi,

The objects your are working with are exposed as IPublishedContent. You are creating a new property on a different type.

Starting with Seocontrols:

You have implemented a property, named like a method. This only exists on the Seocontrols class. In order to use the property, you need to make sure your content inherits from Seocontrols, otherwise you get the error you mention:

CS1061  'IPublishedContent' does not contain a definition for 'FindMetaDescription' and no accessible extension method 'FindMetaDescription'

In the error message, you will also find another solution to this.

Normally you will never get content that it the type of your composition, Seocontrols, but rather something that implements the Seocontrols, as defined in ISeocontrols.

You could then create an extension method, to allow this:

public static class PublishedContentExentions{
    public static string GetMetaDescription(this IPublishedContent content){
        //find description
    }
}

in the method, you can then check if the content implements ISeocontrols:

    public static string GetMetaDescription(this IPublishedContent content){
         if(content is ISeocontrols seocontrols){
           return seocontrols.MetaDescription;
         }
        return null;
    }

You can also add more checks, matching other types:

    public static string GetMetaDescription(this IPublishedContent content){
         if(content is ICategory category){
           return category.CategoryDescription;
         }
         if(content is ISeocontrols seocontrols){
           return seocontrols.MetaDescription;
         }
        return null;
    }

HTH :)

Hi,

I'm in a similar situation here where to be able to call the custom "FindMetaDescription" string that was just added I needed to extend the interface ISeoControls, like such:

public partial interface ISeoControls : IPublishedContent
{
    string FindMetaDescription { get; }
}

This made reaching the property possible, but opened up new issues where I am now getting the following errors:

'CountryPage' does not implement interface member 'ISeoControls.FindMetaDescription'
'Search' does not implement interface member 'ISeoControls.FindMetaDescription'

Unfortunately there is no way to generate this new property in the generated models from umbraco as it will just overwrite this on build. Any suggestions? :p

This is why extension method where invented :)

haha indeed, but for the sake of broadening our knowledge a bit, let us say I want to do this without implementing extension methods (in the way you do in your example) I feel like it should be possible by just extending the partials from umbracos generated files.

You can, but you need just need to implement the interface as the error says. In your CountryPage class you need to create a FindMetaDescription property with a getter, and the same in Search class.

In the corresponding generated.cs ? I will try it out and see if I can get it working :)

Ahh okay, makes more sense now that you say it tbh. I tried implementing directly into the generated and it actually worked (not being overwritten) but it jump straight into the generated GetMetaDescription() method, so extending the other classes would make more sense to make it point to the correct method.

Will update shortly :p

Heyo,

Finally solved it!

public partial class CountryPage : IPublishedContent, ISeoControls
    {
        public string FindMetaDescription 
        { 
            get 
            {
                SeoControls test = new SeoControls(this);
                return test.FindMetaDescription; 
            } 
        }
   }

and then in the SeoControls:

public partial class SeoControls : PublishedContentModel, ISeoControls
    {
        public string FindMetaDescription
        {
            get
            {
                if (String.IsNullOrWhiteSpace(GetMetaDescription(this)))
                {
                    var test = 
                    (string)this.AncestorOrSelf().GetProperty("ingress").Value();
                    if (test.Length > 0)
                    {
                        var finalIngress = test.Length <= 250 ? test : test.Substring(0, 
                                                     250);
                        var pattern = @"\(.*?\)";
                        var final = Regex.Replace(finalIngress, pattern, " ");
                        var finalString = final + "...";
                        return finalString;
                    }
                    return "";
                }
                else
                {
                    return GetMetaDescription(this);
                }
            }
        }
    }

Thanks for all the help along the way to this solution, much appreciated! :)
