Overview

Rather than using a Ransack Search object behind the form, as we do in many other places here we use a custom form object. This is mainly because we have a drop down of (virtual) statues, where each maps to a scope on Admission, where we want the selected ‘status’ to result in its associated scope being called. Ransack doesn’t handle this, not surprisingly. So we have this thin form object around Ransack and do some pre-processing on the Status attribute (see #status_scope).

def status_dropdown_options
  [
    ["Currently admitted", :currently_admitted],
    ["Discharged but missing summary", :discharged_but_missing_a_summary]
  ]
end

#status_scope ⇒ Object

If a status was selected in the drop down, map this to a ransack way of saying “call this scope on Admission”, which is to pass the following (note the true which indicates the scope should be used):

{ name_of_scope: true }

def status_scope
  return {} if status.blank?

  { status.to_sym => true }
end

#submit ⇒ Object

Pass our simple form attributes to Ransack - we lean on Ransack to do querying so as to avoid unnecessary code here, though the magic obfuscates things a little…
