nested form in activeadmin empties values on submit before validation

I have a has_many relationship between Trials and TrialSlots. This is the app/models/trial.rb:

class Trial < ActiveRecord::Base
  validates :title, :start_date, :trial_duration, :subjects_count, presence: true
  has_many :trial_slots
  accepts_nested_attributes_for :trial_slots
end

I want to be able to add and edit TrialSlots from the edit form of a Trial, hence I added this to app/admin/trial.rb

  form do |f|
    # […] some basic inputs skipped for brevity

    f.has_many :trial_slots do |trial_slot|
      f.inputs "Slots" do
        trial_slot.input :start_time, as: :time_picker
        trial_slot.input :end_time, as: :time_picker
      end

    end

    f.actions
  end

Since I'm using Rails4 I already had to add:

  controller do
    def permitted_params
      params.permit(trial: [ :start_date, :trial_duration, :title,
                    :break_duration, :subjects_count, :reward, :location,
                    :agency_name, :agency_address, :contact_name,
                    :contact_email, :contact_phone, trial_slots_attributes: [:start_date, :end_date] ],
                   )
    end
  end

The direct attributes of a Trial are saved as expected. But the attributes of the trial slots are somehow emptied before validation (:start_date and :end_date are both required, thus failing to save). Why?

UPDATE:

I worked around the problem by allowing every parameters.

  controller do
    def permitted_params
      params.permit!
    end
  end

In this specific case, this is reasonable since it's all inside of /admin. However I still wonder how to get this working without the workaround.

Your form has start_time and end_time, while your params permit start_date and end_date. If the code you posted above is correct, that'll likely be your problem.
