Ruby on Rails - Separate Edit Pages

I'm currently trying to add a privacy page to allow my users to modify their privacy settings. I'm using rails-settings to store those settings but creating a layout and updating them is causing me issues.

I created a new page privacy.html.erb, and have it rendering a new partial _privacy.html_erb. The problem is that I cannot simply map the values as if they were just columns.

As in, I can't do <%= f.text_field :name %> as the settings structure is different.

// user.rb has settings stored in this manner.

has_settings do |s|
    s.key :global, :defaults => { :visibility => PRIVACY_ANYONE }
end

Which can be easily gotten through this call.

return settings(:global).visibility
> returns PRIVACY_ANYONE 

So, instead of using form_for, I could instead use form_tag and manually add each field and values. But that sounds like a hacky solution.

And how do I go about saving/updating these values?

Within routes, I've added two routes to get the edit page, and have a post, which does call the correct UserController methods, but the post seems to clear the user so I can't do anything.

// routes.rb

resources :users do
    get 'privacy'
    post 'privacy' => 'users#privacysave'
end

• What would be the best way to handle this case?
• Should I move away from rails-settings and just add another table?
• And how do I update those values?
