A syntax for tables

module Admin::TicketsHelper
  def admin_tickets_table(tickets)
    Tabular.build(tickets) do |table|
      # If we're simply adding a few columns where the header would be the
      # humanized attribute name and the row would contain the attribute `.to_s`
      # then we can use the simple `#columns` method.
      table.columns :id, :title

      # If the column has custom logic for row values, we can use the `#column`
      # method to define it
      table.column :milestone do |ticket, milestone|
        milestone ? milestone.name : "Backlog"
      end

      # Tables frequently have action links in the rightmost column. Here's how
      # we could achieve that. Since we're in a helper we have all the Rails
      # view helpers available to us.
      table.column "Actions" do |ticket|
        link_to "Edit", edit_admin_ticket_path(ticket)
      end
    end
