无法使用附件 gem 上传种子数据“对象的未定义方法 `photos_urls='”

Question

我正在尝试为我的 Photoshoot 模型上传种子数据，该模型由多个 for url 组成，如下所示：

10.times {
  urls = [
    'http://lorempixel.com/400/400/',
    'http://lorempixel.com/400/400/',
    'http://lorempixel.com/400/400/',
    'http://lorempixel.com/400/400/',
    'http://lorempixel.com/400/400/',
    'http://lorempixel.com/400/400/',
    'http://lorempixel.com/400/400/',
    'http://lorempixel.com/400/400/'
  ]
  time = Faker::Time.between(DateTime.now - 1, DateTime.now + 3)
  photoshoot = Photoshoot.new( user_id: Faker::Number.between(1, 19), photograph_id: Faker::Number.between(1, 19), start_time: time, end_time: time + Faker::Number.between(1, 2).hours, message: Faker::TheFreshPrinceOfBelAir.quote )
  photoshoot.save!
  photoshoot.photo_urls = urls
}

但我在种子中收到以下错误消息：

NoMethodError:

的未定义方法 `photos_urls='

我的模型如下：

class Photoshoot < ApplicationRecord
  has_attachment :photos, maximum: 20
  belongs_to :photograph
  belongs_to :user
end

Answer 1

添加附件路径

has_attached_file :photo,
:styles => {
:thumb=> "",
:small  => ""},
:path => "uploads/:class/:attachment/:id_partition/:style/:basename.:extension",
:url => "uploads/:class/:attachment/:id/:style/:basename.:extension"
