尝试使用dropzone保存一组图像而不进行迭代。我切换到迭代图像并尝试保存循环。但铁轨随地吐痰

有人暗示这种问题吗?
答案 0 :(得分:0)
您的问题缺乏有关模型和关系的信息。 凭借如此少的知识,我只是在猜测。 试试这个:
@product = current_vitrine.products.build(params[:product])
if @product.save
if params[:images] && params[:images][:ifoto]
params[:images][:ifoto].values.each do |ifoto|
@product.images.create(ifoto: ifoto)
end
end
end
format.json { render :nothing => true }
