我使用gemfile devise在Rails上进行了登录功能。 然后，我尝试使用gemfile伪造器在seed.rb中创建伪数据，但出现以下错误消息。 请告诉我如何解决。

Rails 6.0.0 设计4.7.1 造假者2.7.0

obj->flat<Type>().data()

#seeds.rb

50.times do
  user=User.new(
    name: Faker::Internet.user_name,email: Faker::Internet.email,password: Faker::Internet.password
  )
end
user.save!

users = User.order(:created_at).take(6)
20.times do
  content = Faker::Lorem.sentence(5)
  users.each { |user| user.diaries.create!(content: body) }
end

@RomanAlekseiev @Sravan 非常感谢

我更改了代码和零件更正。 但是相反，我收到以下错误消息。 请告诉我如何解决。
