Error in sample code

[telljimmy]

The last part of this page shows sample for showing first 100 characters of an article (Fig 42). This is throwing an error saying @item.ArticleContents is not found.

This is the page with issues: https://github.com/umbraco/UmbracoDocs/edit/master/Tutorials/Creating-Basic-Site/Articles-Parent-and-Article-Items.md

Hi @telljimmy Are you sure you have created the Article Content property as mentioned in this image: And can you make sure that you have the same field "alias" (the pad lock text).

[telljimmy]

Sorry for the late reply. I used Article Content instead of Article Contents. But its the same in both document type and in the Macro Partial. So hope it should have worked. images below. Thanks

[telljimmy]

the error is \Views\MacroPartials\listArticles.cshtml(23): error CS1061: 'Umbraco.Core.Models.IPublishedContent' does not contain a definition for 'ArticleContent' and no extension method 'ArticleContent' accepting a first argument of type 'Umbraco.Core.Models.IPublishedContent' could be found (are you missing a using directive or an assembly reference?)" string

To the team: It has to do with the modelsbuilder. We should take some time to validate whether that this tutorials has issues with the new modelsbuilder features.

Hi @telljimmy I am sure that if you do @(Umbraco.Truncate(item.GetPropertyValue<string>("articleContent"), 100) ... it will work.

I also hit this issue when following the tutorial and using the sample code, using GetPropertyValue and casting to a string resolves this. I'm running v7.12.3

Also getting same error here.

I think you might be using the dynamic model (Model.Content) you will need to use the typed model (Model.TypedContent) for this extension method to work

[castlino]

@Jeavon yeah i think you are right, For anyone who's getting the same problem, try below

@Umbraco.Truncate(@Umbraco.Field(item, "articleContents"), 100)

[jmayntzhusen]

I have updated the sample to @(Umbraco.Truncate(item.GetPropertyValue<string>("articleContent"), 100)

Thanks for reporting the issue, will close it now 🙂
