How to enable module in Orchard migration?

Question

I want to enable a specific module in a migration but the module is not enabled immediately.

The issue here seems to be the state of the module, it is set to Rising in table Orchard_Settings_ShellFeatureStateRecord. In this case I cannot enable the module manually in Admin anymore, I need to restart the web server after the migration has been executed to get the module to state Up.

The migration code looks like

public class Migration: Orchard.Data.Migration.DataMigrationImpl
{
  // public
    public Migration(Orchard.Environment.Features.IFeatureManager aFeatureManager)
    {
      mFeatureManager = aFeatureManager;
    }

    ...

    public int UpdateFrom1()
    {
      System.Collections.Generic.Dictionary<string, Orchard.Environment.Extensions.Models.FeatureDescriptor> lFeatures =
        mFeatureManager.GetAvailableFeatures().ToDictionary(m => m.Id, m => m);

      if (lFeatures.ContainsKey("Orchard.Taxonomies"))
        mFeatureManager.EnableFeatures(new string[] {"Orchard.Taxonomies"}, true);

      ...
    }

  // private
    private readonly Orchard.Environment.Features.IFeatureManager mFeatureManager;
}

I also tried using IModuleManager, did not work. Then I tried enabling another simple feature like Orchard.Alias.UI, did not work either.

Is this intended behavior or what might be wrong in the code?

Answer 1

If your feature has a dependency on taxonomies, enabling it will also enable taxonomies. You don't need to do anything else. That is, unless the dependency is something new that you're adding with the new version. In that case, I'd probably display a warning asking the user to enable it, and I'd make the code resilient to taxonomies not being enabled (which is a good idea no matter what)
