Ror Create and Update

Asked

Guys, I’m developing a system in ROR and I have a news table in the bank, and there is a column featured and every time the admin register another news as featured even if there is already one in the bank, the controller has to remove the one that was already highlighted and put this new one. NOTE: The highlighted field is Boolean so it will only change from "true" to "false".

Controller

def create
    # @notice = Notice.new(notice_params)
    featured = params[:notice][:featured]
    category = params[:notice][:category_id]
    user = current_user.secretary.prefecture.county_id
      if featured = 1
        @notice = Notice.where(county_id: user, category_id: category,  featured: true)
        if @notice.present?
          @notice = Notice.find(@notice.id).update(featured: false) rescue nil
        end
      end
 end

  • and what is your doubt? what is wrong?

  • Hello Ricardo, thank you so much for asking, but I’ve already solved. I wanted to feature a headline and if there ever was one featured in the same category it would remove the headline from the one that already existed and add the new headline.

After much trying I managed to run. Thank you!

  def create
  featured = params[:notice][:featured]
  puts featured
  category = params[:notice][:category_id]
  user = current_user.secretary.prefecture.county_id

    if featured.to_s == "1"
      puts "destaque selecionado, buscando destaque ativo"
      @n = Notice.where(county_id: user, category_id: category,  featured: true)
      # b = @n
      puts "Registo encontrado ", @n.ids
      if [email protected]?
        puts "A busca n foi vazia"
        a = @n.where(id: @n.ids).update(featured: false)
        puts "O registo ", @n.ids, " foi alterado"
      end
    end
    @notice = Notice.new(notice_params)
    @notice.county_id = user
      respond_to do |format|
      if @notice.save
          format.html { redirect_to action: :index}
          format.json { render :show, status: :created, location: @notice }
        # format.html { redirect_to @notice, notice: 'Notice was successfully created.' }
        # format.json { render :show, status: :created, location: @notice }
        else
          format.html { redirect_to action: :index}
          format.json { render :show, status: :created, location: @notice }
        # format.html { render :new }
        # format.json { render json: @notice.errors, status: :unprocessable_entity }
        end
      end
  end
