NameError：未初始化的常量Plaqueorder :: ShrineImageUploader在Rails上使用Shrine 2.8时5.1.4

Question

无论我做什么，我都无法使Shrine正常工作，我使用的是最简单的设置。

分贝/ schema.rb

create_table "plaqueorders", force: :cascade do |t| 
    ... 
    t.text "image_data" 
    ... 

初始化/ shrine.rb

require 'shrine' 
require 'shrine/storage/file_system' 

Shrine.storages = { 
cache: Shrine::Storage::FileSystem.new('public', prefix: 'uploads/cache'), 
store: Shrine::Storage::FileSystem.new('public', prefix: 'uploads/store'), 
} 

Shrine.plugin :activerecord 
Shrine.plugin :cached_attachment_data # for forms 

上传/ image_uploader.rb

class ShrineImageUploader < Shrine 
end 

个型号/ plaqueorder.rb

class Plaqueorder < ApplicationRecord 
    belongs_to :user 
    validates :plaque_type, presence: true 
    include ShrineImageUploader[:image] 
end 

Answer 1

韦尔普，下手，似乎image_uploader.rb定义ShrineImageUploader。我会认为该文件将被命名为shrine_image_uploader.rb或该班级将被命名为ImageUploader。

否则，您的命名不匹配。
