Peek::Select

Peek into any collection in your app.

Things this peek view provides:

• Present options from a collection as a select list
• Run a piece of JavaScript code when an option is selected

An example use would be to list subdomains served by an application and switch between them when a new option is selected, as in Usage below.

Add this line to your application's Gemfile:

gem 'peek-select'

And then execute:

$ bundle

Or install it yourself as:

$ gem install peek-select

Add something like the following to your config/initializers/peek.rb:

Peek.into Peek::Views::Select,
  collection: lambda { Site.order(:subdomain).pluck(:name, :subdomain) },
  selected: lambda { |controller| controller.current_site.subdomain },
  onchange: "window.location.hostname=" \
    "window.location.hostname.replace(/^[^.]*\.?(?=mysite.com)/," \
    "this.value+'.');"

The options are:

• collection - A collection or lambda returning a collection suitable for passing to options_for_select. Defaults to the empty array.
• selected - The value in collection that should be selected.
• onchange - JavaScript for the <select> element's onchange attribute.
• name - String used to generate the <select> element's name and id attributes. The value used is peek-select-#{@name}
