Custom fields or metadata to link jobId to some custom value

question
1

Is there any way to add custom fields saying project owner and project id so I can keep track of which jobs have been done for particular project. I am trying to make it so that if you are looking at the project detail page the progress bar will be displayed even you refresh the browser.

Using a IClientFilter, you can add parameters to the job.

 public class HangfireJobDecorator : IClientFilter
    {
        private readonly IMyService _service;
        public HangfireJobDecorator (IMyService service)
        {
            _service = service;
        }

        public void OnCreating(CreatingContext filterContext)
        {
            filterContext.SetJobParameter("MyValue", _service.GetMyValue());
        }

        public void OnCreated(CreatedContext filterContext) {  }
    }

You’ll add this filter where you setup hangfire in your application.

GlobalJobFilters.Filters.Add(new HangfireJobDecorator(new MyService))

This is only suitable if you are able to add your wanted parameters in a generic way.
If you need to set parameters when you queue the job, you can use the storage connection:

JobStorage.Current.GetConnection().SetJobParameter(jobId, "foo", someLocalVariable);

The question, though, is if this is really what you want. This will store parameters on the job, that you can get hold of inside the job through the PerformContext-parameter of your background job method. It might be that you want things the other way around - that instead of storing project details on the job, you want to store background job id in the project…

It that is the case, you should do exactly that: store the jobid that is returned from the Enqueue-call, and later fetch the status of that job:

JobStorage.Current.GetConnection().GetStateData(jobId)

Thanks. This is what I was looking for. I am going to save the project id in JobParam table
