无法填充种子文件中的数据

问题描述

我正在尝试通过命令seed_fu使用gem acts-as-taggable-on和rails db:seed_fu来填充数据。
但出现错误NameError: uninitialized constant SeedFu :: Runner :: Tagging.
如何正确填充数据？
如果有人知道，请告诉我。

显示错误
NameError: uninitialized constant SeedFu::Runner::Tagging

会发生什么
您可以使用seed_fu将行为可标记的数据（标记表和标记表）填充到数据库中。

操作环境

• MacOS：Mojave
• Ruby：2.5.7
• 路轨：5.1.7
• 行为可标记：6.5.0
• seed_fu：2.3.9

我的代码

• lib / tasks / seed_fu_gen.rake

namespace :seed_fu_gen do
  desc "back up datas to folder."
  task all: :environment do |_t|
  :
  :
    # tagging.rb
    taggings = ActsAsTaggableOn::Tagging.all
    SeedFu::Writer.write("db/fixtures/tagging.rb",class_name: "Tagging",seed_type: :seed_once) do |writer|
      taggings.each do |tgg|
        writer << tgg.attributes.except("created_at","updated_at")
      end
    end

    # tag.rb
    tags = ActsAsTaggableOn::Tag.all
    SeedFu::Writer.write("db/fixtures/tag.rb",class_name: "Tag",seed_type: :seed_once) do |writer|
      tags.each do |tg|
        writer << tg.attributes.except("created_at","updated_at")
      end
    end
  :
  :
  end
end
