# 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).
class AdmissionSearchForm
include ActiveModel::Model
include Virtus::Model
attribute :hospital_unit_id, Integer
attribute :hospital_ward_id, Integer
attribute :status, String
attribute :term, String
# 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...
def submit
@search ||= begin
options = {
hospital_ward_hospital_unit_id_eq: hospital_unit_id,

end
# 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 }
