레일 및 Carrierewave : belongs_to 모델로 이미지 (하드 코딩 된) 문자열을 NULL로 저장 하시겠습니까?

Question

하드 코딩 된 문자열이 서버에서 어떻게 NULL이 될 수 있습니까? 나는 같은 접근법으로 다른 접근법으로 그것을 저장하려고 노력했다. Carrierwave에서 nginx, mysql, react 및 rails 5로 도커를 실행 중입니다.

create_table "galleries", force: :cascade, options: "ENGINE=InnoDB DEFAULT CHARSET=utf8" do |t| 
    t.string "name" 
    t.text  "description", limit: 65535 
    t.datetime "created_at",    null: false 
    t.datetime "updated_at",    null: false 
end 

create_table "gallery_images", force: :cascade, options: "ENGINE=InnoDB DEFAULT CHARSET=utf8" do |t| 
    t.integer "gallery_id" 
    t.string "image" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false

class ImageForm extends React.Component { 
    return (

    has_many :gallery_images 
    accepts_nested_attributes_for :gallery_images

class GalleryImage < ApplicationRecord 
    mount_uploader :image, ImageUploader 
    belongs_to :gallery 
end 

# POST /galleries 
def create 
    @gallery = Gallery.new(gallery_params) 
    logger.debug(params[:gallery_images]['image'][0])  
    if @gallery.save 
    @gallery_images = GalleryImage.create!(gallery_id: @gallery.id, image: "5_star.png")  
    redirect_to @gallery, notice: 'Gallery was successfully created.' 
    else 
    render :new 
end 
def gallery_params 
    params.require(:gallery).permit(:name, :description, gallery_images_attributes: [:id, :gallery_id, :image]) 
end

Answer 1

형식을 camelcase로 변경하여 해결했습니다. enctype -> encType accept-charset -> acceptCharset입니다. 두 번째로 값을 바꿀 수있는 방법을 아직 모르겠다.
