In my Rails form I have a field for selecting a person's rate/hour. I would like this to display in my form as a collection_select dropdown with select options of the format:

$1.00 per hour

$1.25 per hour

$1.50 per hour

etc.

Currently I have a rate field t.decimal "rate"

And my form (I'm using simple form) that currently just displays numbers with two decimal places: 

<%= f.input :rate, label:false, collection: (0..100).step(0.25).map{ |n| number_with_precision(n, precision: 2) }, input_html: {class: "rate-select", min: '0'}  %>

What would be my best way of displaying the select dropdown in my desired format above with currency, and 'per hour' surrounding the rate but only saving the rate as a decimal? For now the currency doesn't need to be selected or stored so basically I'm just looking to extract the numerical portion of the select options.

You can do so by passing a 2D array to collection option. E.g.

collection: [['$1.00 per hour', 1.00], ['$1.25 per hour', 1.25]]

Where each subarray represents the text and value of an option, accordingly.
