strong parameters for active admin

[sutherland007]

Update the active admin file (notice the comments in the code).
here is my example:

ActiveAdmin.register Survey::Survey do
  permit_params :name, :attempts_number, :description, :finished, :active #mandatory for rails 4 and newer versions of active admin
  menu :label => I18n.t("surveys")

  filter  :name,
          :as => :select,
          :collection => proc {
              Survey::Survey.select("distinct(name)").collect { |c|
                [c.name, c.name]
              }
          }
  filter :active #,
         #:as => :select,
         #:collection => ["true", "false"]
         # no needed activeadmin detects a boolean as yes or not automatically

  filter :created_at

  index do
    column :name
    column :description
    column :active
    column :attempts_number
    column :finished
    column :created_at
    actions #default_actions
  end

  form do |f|
    f.inputs I18n.t("survey_details") do
      f.input  :name
      f.input  :description
      f.input  :active #, :as => :select, :collection => ["true", "false"] no needed activeadmin detects a boolean input as checkbox
      f.input  :attempts_number
    end
    f.inputs I18n.t("questions") do
      f.has_many :questions do |q|
        q.input :text
        q.has_many :options do |a|
          a.input  :text
          a.input  :correct
        end
      end
    end
    f.actions #buttons
  end

end

There is another thing, the questions are not saving correctly, you can create a survey but when you save it, the questions were not saved, or when you try to save the survey a validation says " Survey without questions cannot be activated" in the active field and the questions that you've made, disappeared

I'm using active admin 1.0.0 pre 4
Rails 4.2.6
Ruby 2.20
the gsurvey gem "survey", "~> 0.1"

i've solved it by adding this in the paramaters:
permit_params :name, :description, :active, :attempts_number, :questions_attributes => [:survey_id, :text], :options_attributes => [:question_id, :weight, :text, :correct]
please consider my solution for rails 4 support and activeadmin newer versions.
