As you can see i try to upload multiple images, controller is such:
class CarPhotosController < ApplicationController
before_action :set_car_photo, only: [:show, :edit, :update, :destroy]
def new
@car_photo = CarPhoto.new
end
def create
#binding.pry
@car_photo = CarPhoto.new(car_photo: car_photo_params[:car_photo].first)
#binding.pry
#@car_photo.user_id = current_user.id
respond_to do |format|
if @car_photo.save #&& user_signed_in?
format.html { redirect_to @car_photo, notice: 'Photo was successfully created.' }
format.json { data = {id: @car_photo.id, thumb: view_context.image_tag(@car_photo.car_photo.url(:thumb))}
render json: data, status: :created, location: @car_photo }
else
format.html { render action: "new" }
format.json { render json: @car_photo.errors, status: :unprocessable_entity }
end
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_car_photo
@car_photo = CarPhoto.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def car_photo_params
params.require(:car_photo).permit(:car_photo, {:car_photo => []})
end
end
and when i submit some image in chrome log i see, that server return such json:
{"id":31,"thumb":"\u003Cimg alt=\"1\" src=\"/system/car_photos/car_photos/000/000/031/thumb/1.jpg?1394785415\" /\u003E"}
and in db i see that it is saved, but why in view i get :
Error Empty file upload result
what i do wrong? and how to solve it?
