Searching on an Enum Field with Ransack

Question

I've got a table, 'jobs' with a enum field 'status'. status has the following enum set:

enum status: [ :draft, :active, :archived ]

using ransack, how do I filter the table for, say, all active records?

Answer 1

You can declare own ransacker in model like this:

ransacker :status, formatter: proc {|v| statuses[v]} do |parent|
  parent.table[:status]
end

Then You can use default ransack syntax _eq to check equality like this:

Model.ransack(status_eq: 'active').result

Edit: If column name doesn't change you can skip block of code:

ransacker :status, formatter: proc {|v| statuses[v]}

Answer 2

This is something I use in my views for enums and ransack:

<%= f.select :status_eq, Model.statuses.to_a.map { |w| [w[0].humanize, w[1]] },
                         {:include_blank => true} %>
