在验证文件大小上缺少载波转换

Question

我尝试这个https://gist.github.com/chrisbloom7/1009861来验证载波上的文件大小

1. 我创建了lib/file_size_validator.rb
2. 我把一些翻译文件yml (wrong_size, size_too_small,size_too_big, number.human.storage_units.units.mb)
3. 把require 'file_size_validator'放到我的模型中
重启服务器

没有什么是被忽视的

但是当我尝试上传24MB大小的视频时，我得到了错误:

I18n::MissingTranslationData in VideosController#create
translation missing: id.number.human.storage_units.units.mb
lib/file_size_validator.rb:51:in `block in validate_each'
lib/file_size_validator.rb:42:in `each'
lib/file_size_validator.rb:42:in `validate_each'
app/controllers/videos_controller.rb:67:in `create'

id.yml是这样的:

id:
  errors:
    messages:
      wrong_size: "is the wrong size (should be %{file_size})"
      size_too_small: "is too small (should be at least %{file_size})"
      size_too_big: "is too big (should be at most %{file_size})
  number:
    human:  
      storage_units:
         format: "%n %u"
      units:
         byte:
           one: "Byte"
           other: "Bytes"
         kb: "KB"
         mb: "MB"
         gb: "GB"
         tb: "TB"

这里是video.rb

require 'file_size_validator'
class video < ActiveRecord::Base
mount_uploader :file, VideoUploader
before_save :update_file_attributes, :validatefile
before_update :update_file_attributes
validates :file,
  presence: true,
  :file_size => { 
      :maximum => 20.megabytes.to_i 
    }

videos_controller.rb第67行

@video = Video.create(params[:video])

你能帮我纠正我的步骤和代码吗?

谢谢

您的翻译文件中有嵌套错误。应该是

id:
  errors:
    messages:
      wrong_size: "is the wrong size (should be %{file_size})"
      size_too_small: "is too small (should be at least %{file_size})"
      size_too_big: "is too big (should be at most %{file_size})
  number:
    human:  
      storage_units:
        format: "%n %u"
        units:
           byte:
             one: "Byte"
             other: "Bytes"
           kb: "KB"
           mb: "MB"
           gb: "GB"
           tb: "TB"
