I've searched around but haven't found an answer, but I'm also not sure what terms to search for, so please point me to similar questions if you know of any.

Scenario: I have posts. I have an admin side and a public side. I want a single post displayed on the public side front page.

On the admin side, on the posts index page, I would like to be able to select a radio button next to the post I want displayed on the front page. My guess is I would need a form, radio buttons for each of the posts, and an update button. But that's as far as I'm able to get on my own.

I've looked into virtual attributes, but I don't think that's what I need, or is it? What's a good way to accomplish what I need?

Thanks in advance everyone.

You could add a "public" field to your posts model, and access it via a checkbox on the edit post form. In your controller on a create or update, check to see if the public field is true, if so then you'll need to run something like Post.update_all(['public = ?', false], ['id != ?', current_post_id]) in order to revert any existing public posts back to private.

Alternatively, you could create a simple model for AppData (:id => :integer, :key => :string, :value => :string) and store the id of the currently selected public post on a row in that table. To keep it simple, you'll want to serialize the :value field in your model. In this case, you would use just an unattached checkbox_tag in your view and capture that value from the params hash. If it's checked, then you'll need to update the AppData row with the new id.
