Question

我使用了邪恶的宝石作为我的形式。当用户上传照片时，他们可以在与..../steps/picture相同的页面上看到。在图片页面，用户可以破坏图片。当用户点击我希望他们重定向到步骤/图片页面，但无论我尝试什么，我都会得到错误。船和图片相关但不是嵌套路线。

这是我的图片控制器#destroy操作;

def destroy

@picture = @boat.pictures.find(params[:id])
if @picture.destroy
 ######SOMETHING GOES HERE#########
  flash[:notice] = "Successfully destroyed picture."
else
  render json: { message: @picture.errors.full_messages.join(',') }
end

端

#boat_steps控制器;

class BoatStepsController < ApplicationController
    include Wicked::Wizard


    before_action :logged_in_user
    steps :model, :pricing, :description, :features, :picture

    def show
        @boat = current_user.boats.last
    case step
    when :picture
        @picture = @boat.pictures.new
        @pictures = @boat.pictures.all
    end
        render_wizard

    end

    def update
        @boat = current_user.boats.last
        @boat.update(boat_params)
        case step
    when :picture
        @picture.update(picture_params)

    end

        render_wizard @boat


    end


private

    def finish_wizard_path
        new_boat_picture_path(@boat, @picture)
    end



    def boat_params
      params.require(:boat).permit(......)
    end

    def picture_params
      params.require(:picture).permit(......)
    end


end

Answer 1

对于邪恶的向导，在rake routes上没有显示的视图上有可用的路径助手。

尝试redirect_to wizard_path(:picture)

您可以在此处找到有关视图可用的恶意助手的更多信息：https://github.com/schneems/wicked#quick-reference

这些帮助程序将在使用render_wizard呈现的视图上可用。在向导之外，该步骤将作为RESTful路由的:id传递。要在图片上重定向到boat_steps / show，请尝试redirect_to boat_step_path(id: :picture)。生成的网址应为/boat_steps/picture。

删除操作后的邪恶redirect_to
