But I'm adding the vacancies 'manually' in table vacancy. My controller: def create @hr_curriculum_generic = HrCurriculumGeneric.new(params[:hr_curriculum_generic]) # Tabela CandidatosxVagas unless params[:vacancy_ids].nil? @vacancies_ids = params[:vacancy_ids] -- my form: @vacancies_ids.each do |vacancy_id| # Armazena os id do curriculum, vaga e do cargo na tabela CandidatosxVagas @candidates_vacancies = CandidatesVacancy.new <% @vacancies =

I'm developing a small application in Ruby-On-Rails. I want to hide a div in an html.erb file until a link is clicked. What is the simplest way to do this?

I want to manually precompile some assets in my dev environment (to check the content of the compiled js and css files) from the command line.
