嵌套模型邪恶，呈现页面

我有嵌套模型，船has_many :pictures，图片belongs_to :boat。用户创建了一艘船后，我使用了邪恶的宝石来制作步骤。最后一步是图片步骤，用户可以拖动图片等等。它可以保存而不会出现问题。但是，当用户放下图片时，它会再次保存并呈现页面（jQuery），以显示添加的内容，因此用户可以在此处销毁图片。嵌套模型邪恶，呈现页面

但是，它呈现与空图片的页面，但是当我检查它保存的数据库。所以这可能是因为boat_steps #show的行动。但我找不到。由于图片页面不属于步骤完成向导路径为图片。但我想改变它。我刷新页面的原因是我无法完成图片jquery。这是dropzonejs，但如果我在代码中留下评论。我可以从数据库中删除照片，但它粘在屏幕上。

这里是boat_steps controller

class BoatStepsController < ApplicationController 
    include Wicked::Wizard 


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

    def show #PROBABLY I SHOULD CHANGE HERE 
     @boat = current_user.boats.last 
     @picture = @boat.pictures.new 
     render_wizard 
    end 

    def update 
     @boat = current_user.boats.last 
     @picture = @boat.pictures.new 
     case steps 
      when :picture 
       @picture.update(picture_params) 
       render_wizard @picture 
      else 
      @boat.update(boat_params) 
      render_wizard @boat 
     end 

    end 


private 

    def finish_wizard_path 
     new_boat_picture_path(@boat, @picture)

    end 

    def picture_params 
     params.require(:picture).permit(:name, :brand_id, :image) 
    end 


end

这里是picture.html.erb

EDIT 1：

这里画面控制器

class PicturesController < ApplicationController 
    before_action :logged_in_user 
    before_filter :load_parent 



    def new 
    @picture = @boat.pictures.new 
    @pictures = @boat.pictures.all 
    end 

    def show 
    @picture = @boat.pictures.find(params[:id]) 
    end 


    def create 

    @picture = @boat.pictures.new(picture_params) 

    if @picture.save 
    render json: { message: "success", fileID: @picture.id, boatID: @boat.id }, :status => 200 

    else 
     render json: { error: @picture.errors.full_messages.join(',')}, :status => 400 

    end 

    end 


    def edit 
    @picture = Picture.find(params[:id]) 
    end 

    def update 
    @picture = @boat.pictures.find(params[:id]) 

    if @picture.update_attributes(picture_params) 
     flash[:notice] = "Successfully updated picture." 
     render 'index' 
    else 
     render 'edit' 
    end 
    end 

    def destroy 

    @picture = @boat.pictures.find(params[:id]) 
    if @picture.destroy 
    #render json: { message: "File deleted from server" } 
     redirect_to new_boat_picture_path(@boat, @picture) 
     flash[:notice] = "Successfully destroyed picture." 
    else 
     render json: { message: @picture.errors.full_messages.join(',') } 
    end 
    #flash[:notice] = "Successfully destroyed picture." 
    #redirect_to new_boat_picture_path(@boat, @picture) 
    #redirect_to boat_pictures_path(@boat) 
    #redirect_to boat_path(@boat) 
    end 




    private 

    def picture_params 
     params.require(:picture).permit(:name, :image) 
    end 

    def load_parent 
    @boat = Boat.find(params[:boat_id]) 
    end 





end

编辑2：

新演出的动作是;

def show 
     @boat = current_user.boats.last 
     @picture = @boat.pictures.new 
     @pictures = @boat.pictures.all 

     render_wizard 

    end

但是当我降落在....boat_steps/picture URL，它显示了一些空的照片，而不用行不通的。这是为什么？
