Context is null in GlassMapperConfigurator

Question

I'm trying to access Sitecore 10.2 model fields using Glass.Mapper.Sc.92 version 5.8, and registered all Glass.Mapper services in GlassMapperConfigurator class. However facing the "Context is null" issue.

Created another class to register the controller

public class GlassCustomConfigurator: IServicesConfigurator
{
    public void Configure(IServiceCollection serviceCollection)
    {
        serviceCollection.AddTransient<FooterController>();
    }
}

Controller code:

public class FooterController : Controller
{
    private readonly IMvcContext _mvcContext;

    public FooterController(IMvcContext mvcContext)
    {
        _mvcContext = mvcContext;
    }
    public ActionResult Footer()
    {
        var model = _mvcContext.GetContextItem<FooterModel>();
        return View(model);
    }
}

GlassCustom.config to register the services

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
    <sitecore>
        <services>
            <configurator type="Test.GlassCustomConfigurator, Test" />
            <configurator type="Test.GlassMapperConfigurator, Test" />
        </services>
    </sitecore>
</configuration>

Any idea how can I fix this issue?

Answer 1

Glass.Mapper.Sc requires a set of configuration files to be deployed to Sitecore:

https://github.com/mikeedwards83/Glass.Mapper/tree/master/Source/Glass.Mapper.Sc/App_Config/Include/Glass

Before the move the packageReferences, these config files would automatically be added and deployed to your Sitecore solution.

Now you will need to manually add them to your Visual Studio solution to ensure they are correctly deployed.

Answer 2

Try something like this maybe:

serviceCollection.AddScoped(_ => CreateSitecoreContextService());

and CreateSitecoreContextService method:

private static ISitecoreService CreateSitecoreContextService()
{
  var sitecoreServiceThunk = Get<Func<Database, ISitecoreService>>();
  return sitecoreServiceThunk(Sitecore.Context.Database);
}
