问题描述
从反应到后端的数据流还可以,我有204状态代码。在控制台中,我看到图像参数被检测到。
在2020-09-13 17:25:50 +0200开始对:: 1进行POST“ /培训” (0.1ms)选择sqlite_version(*) 由TrainingController#create处理为HTML 参数:{“ description” =>“ test”,“ image” =>“ data:image / png ...(长消息)
最后我看到这些操作
(0.1ms) begin transaction
↳ app/controllers/training_controller.rb:20:in `create'
Training Create (0.2ms) INSERT INTO "trainings" ("description","image","created_at","updated_at") VALUES (?,?,?) [["description","test"],["image",nil],["created_at","2020-09-13 15:25:50.715990"],["updated_at","2020-09-13 15:25:50.715990"]]
↳ app/controllers/training_controller.rb:20:in `create'
(3.9ms) commit transaction
↳ app/controllers/training_controller.rb:20:in `create'
No template found for TrainingController#create,rendering head :no_content
Completed 204 No Content in 10ms (ActiveRecord: 4.2ms | Allocations: 4126)
现在我们看到我们的对象图像为零,我不知道为什么。 这是我的训练控制器和图片上传器
-
训练控制器
class TrainingController
before_action :set_training,only: [:show,:edit,:update] def index @training = Training.all Training.order("created_at DESC") render json: @training end def show end def new @training = Training.new end def create training = Training.new(training_params) training.save end def edit end def update @training.update_attributes(training_params) end private def training_params params.require(:training).permit(:description,:image) end def set_training @training = Training.find(params[:id]) end
结束
- ImageUploader
attr_accessor :description,:image
storage :file
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
end
what is bad?
