hirb.yml fields spec ignored when class name is "Task"

[pdobb]

This seems odd... so please let me know if you'd like me to try anything further to help debug. I've set up several custom field sets for several classes and they all work great, except for the one that I've defined for my Task class.

A very simplified example from my hirb.yml file:

:output:
  Task:
    :options:
      :fields:
        - id

Now I load a fresh Rails console and do:

Task.all

The output is a table that shows every column in my tasks table, instead of just the id column.

Now... my Task class is a superclass for a few other Task types (e.g. SubscribeTask). Let's try this on the console:

SubscribeTask.all

Nope. Same table that's showing all columns. But that's OK -- I expected that. I'm just saying to lead into my next discovery.

Recently, I tried changing my hirb.yml to use one of the subclass names like this:

:output:
  SubscribeTask:
    :options:
      :fields:
        - id

Now I load a fresh Rails console and do:

SubscribeTask.all

The output is a table that shows just the id column as I was expecting.

So what is it about the class name "Task" that is causing hirb to not render the table with my configured columns?

Thanks so much for your help!

P.S. I've observed this in Ruby 1.8.7, Rails 3.0.5 (also Rails 2.3.9)

Seems odd but there's not much I can do without your code or specific errors. Have you tried a vanilla rails app with just those two models copied over? If so, is it up on github?

If you want to make sure hirb works with Task, you can always:

 puts Hirb::Helpers::AutoTable.render(Task.all, :fields => [:id])

Yes, now I have and now I do. Here you go: https://github.com/pdobb/hirb_test

Thanks again!

Ok. Now I understand the issue. You're doing Task.all but you're not getting back task objects. You're getting back SubscribeTask objects. Your configuration only supported Task objects. To have Task all and its subclasses receive the configuration, add the :ancestor option:

:output:
  Task:
    :ancestor: true
    :options:
      :fields:
       - id

Brilliant! That's exactly what I needed and makes sense even. Thanks very much!
