Answer 1

Поскольку родитель может подать заявку на финансирование только для одного ребенка за один раз, разрешите ему выбрать, какой ребенок в форме финансирования, и передать: child_id как часть параметров финансирования в действие FundingsController # create.

fundings_controller.rb:

def create
  @funding = Funding.new(funding_params)

  if @funding.save
    flash[:success] = "Thankyou for submitting"
    redirect_to funding_path(@funding)
  else 
    render 'new'
  end
end

application_controller.rb

def current_user
  @current_user ||= Family.find(session[:family_id]) if session[:family_id]
end

def parent_user
  @parent_user ||= Parent.find(session[:family_id]) if session[:family_id]
end

def current_children
  puts session[:family_id]
  @current_children ||= Child.where(:parent_id => parent_user.id) if session[:family_id]
end
helper_method :current_children

Answer 2

Глядя на ваши модели, это должно быть частью таблиц базы данных.

|Family |Parent    |Child      |Funding   |Organisation  |
|-------+----------+-----------+----------+--------------|
|id     | id       | id        |id        |id            |
|-------+----------+-----------+----------+--------------|
|       |family_id |parent_id  |child_id  |founding_id   |

Я вижу проблему в том, что при создании нового финансирования вы можете добавить только одного ребенка.Но вы получили коллекцию, тогда вы ограничены 1, чтобы она заработала.

Но вы добавляете только первого дочернего элемента, выбранного для current_user (.limit(1)).

Что вам нужно сделать, этодля каждого из детей, принадлежащих родителям, принадлежащим к current_user (находится в «Семье»), необходимо создать новое финансирование.

Но код сильно меняется.Удалите .limit(1), чтобы получить всю коллекцию детей, отсканируйте коллекцию и создайте финансирование для каждого ребенка.

Но я думаю, что для этого вам нужно создать новое действие в другом контроллере.

Или, но я не знаю вашей цели, рассмотрите возможность использования другой ассоциации, например has_and_belongs_to_many между Child и Funding.
