Rails - Creating a select tag from a object hash

Question

I need to create a select box from the values available in a Hash.

For instance, I have a \'thing\' and the \'thing\' has a variety of status fields:

1 =

Just as Schrockwell has said:

Hash.each |a| returns an array of the form a = [key, value], so for the hash @status_fields you can write:

<%= collection_select('thing', 'status', @status_fields, :first, :last) %>

Alternatively, if you'd like the key to show up in the select list and the value point to the select list value, then:

<%= collection_select('thing', 'status', @status_fields, :last, :first) %>

This will select the option given by thing.status or nothing if nil is returned

If you want to just create any selection not tied to an object use

<%= select_tag('name', options_from_collection_for_select(@status_fields, :first, :last, '2')) %>

where '2' is the index of the desired selection
