U4-7751 - The template markup generated can be incorrect - based on casing which causes YSOD

Tags: ModelsBuilder

Relates to: U4-7747

Example, create a doc type:


the markup generated is:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

which is wrong, the class name is 'TEst'

The models builder gets the class name as:

ClrName = contentType.Alias.ToCleanString(CleanStringType.ConvertCase | CleanStringType.PascalCase)

BUT then it is possible to change that name via attributes. So although the alias is "foo", the class name could be "Bar". The ''only'' proper way to know the class name associated to an alias is by querying the published content model factory.

The right way to do it is to modify the IPublishedContentModelFactory interface to add the

Type GetModelType(string contentTypeAlias);

method - because only the factory knows about the type. If we don't want to change that interface ''now'' for compatibility reasons, there is an ugly way to do it that would work with the built-in factory - but probably not with any other factory. And Ditto has its own factory.
