    Hangfire Umbraco Context Access

    Followed this guide to update content via hangfire:

    https://cultiv.nl/blog/using-hangfire-to-update-umbraco-content/

    I have hangfire installed and running successfully, unfortunatly I cannot seem to access the umbraco context on a hangfire job, everything I have read indicates you can just inject it in and off you go.

    But doing this:

    public void ManipulateContent(PerformContext context)
{
    using var _ = _umbracoContextFactory.EnsureUmbracoContext();
    using var serviceScope = _serviceProvider.CreateScope();

    var query = serviceScope.ServiceProvider.GetRequiredService<IPublishedContentQuery>();
    var rootNode = query.ContentAtRoot().FirstOrDefault();

    if (rootNode == null) return;

    context.WriteLine($"Root node - Id: {rootNode.Id} | Name: {rootNode.Name}");
}

    The rootNode is always null. I am a bit stumped, anyone got any tips on direction?

    Hi,

    I don't know if this will, help you, but I use a class which contains my Hangfir Jobs.

    public partial class ScheduledJobs
{
    private readonly IContentService _contentService;
    private readonly ILogger<ScheduledJobs> _logger;
    private readonly IUmbracoContextFactory _umbracoContextFactory;

    public ScheduledJobs(IUmbracoContextFactory umbracoContextFactory, IContentService contentservice, ILogger<ScheduledJobs> logger)
    {
        _contentService = contentservice;
        _umbracoContextFactory = umbracoContextFactory;
        _logger = logger;
    }

    [AutomaticRetry(Attempts = 2)]
    [JobDisplayName("Synchronise Products")]
    public void SyncProducts(PerformContext hangfire)
    {
        using (var cref = _umbracoContextFactory.EnsureUmbracoContext())
        {
            //get the Id for the shop
            Guid parentGuid;
            var home = _contentService.GetRootContent().Where(x => x.ContentType.Alias == "home").First();
            var children = _contentService.GetPagedChildren(home.Id, 0, 100, out var totalrec);
            if (children != null)
            {
                parentGuid = children.First(x => x.ContentType.Alias == "shop").Key;
            }
            else
            {
                _logger.LogError("Error retreiving Product Parent Page {Alias}", "shop");
                return;
            }

            var shop = _contentService.GetById(parentGuid);

           ..... code shortened for example.
        }
    }
}

    The jobs are added using a dashboard and API controller, example below

        public class HangfireJobsController : UmbracoApiController 
    {
        private readonly ILogger<ScheduledJobs.ScheduledJobs> _logger;
        private readonly IContentService _contentService;
        private readonly IUmbracoContextFactory _umbracoContextFactory;

        public HangfireJobsController( ILogger<ScheduledJobs.ScheduledJobs> logger, IContentService contentService, IUmbracoContextFactory umbracoContextFactory)
        {
            _logger = logger;
            _contentService = contentService;
            _umbracoContextFactory = umbracoContextFactory;

        }

        public JsonResult SyncProducts(string Cron = "00 01 * * *")
        {

            new ScheduledJobs.ScheduledJobs(_umbracoContextFactory, _contentService, _logger).SyncProducts(null);
            RecurringJob.AddOrUpdate<ScheduledJobs.ScheduledJobs>(x => x.SyncProducts(null), Cron);

            return new JsonResult("OK");

        }
}
