Use hash as source for collection_check_boxes

Question

I have the following hash:

FIELD_LIST = {
  -1 => 'User',
  -2 => 'Duration',
  -3 => 'Price',
  -4 => 'Invoiced'
}

I want to use this with collection_check_boxes.

The manual says:

The parameters: value_method and: text_method are methods to be called for each member of the collection.

So I tried this:

= f.collection_check_boxes TimesheetReport::FIELD_LIST, [0], [1], :input_html => { :class => 'checkbox' }

But this is giving me an error.

How can a hash be used as input to create checkboxes?

Actually, it is possible. A hash is technically a collection of objects. You can do something like this:

= f.collection_check_boxes :field_name, TimesheetReport::FIELD_LIST, :first, :last, :input_html => { :class => 'checkbox' }

Replace with the :field_name

actual name of your attribute where you want to store this data. It should work.
