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在循环中。但铁轨随地吐痰Rails如何在迭代上构建
ActiveRecord :: StatementInvalid at/products ================================= ==========> SQLite3 :: ConstraintException:NOT NULL约束失败: images.product_id:INSERT INTO“images”(“created_at”,“ifoto”, “product_data_id”,“product_id”,“ updated_at“)VALUES(?,?,?,?,?) app/controllers/products_controller.rb,214行 ----------------------- -------------------------
ruby 209 210 if params[:images] && params[:images][:ifoto] 211 params[:images][:ifoto].values.each do |ifoto| 212 213 @image.ifoto = ifoto > 214 @image.save 215 216 217 end 218 render :nothing => true 219
App backtrace ------------- - app/controllers/products_controller.rb :214:在block (3 levels) in create' - app/controllers/products_controller.rb:211:in

这里是悬浮窗代码
format.json do
@product = current_vitrine.products.build(params[:product])
@image = @product.images.build(params[:images])
if params[:images] && params[:images][:ifoto]
params[:images][:ifoto].values.each do |ifoto|
@image.ifoto = ifoto
@image.save
end
render :nothing => true
end
end
有人有一个提示这类问题?
非常感谢你! – japalow
