Ruby on rails 4 在factory gril中定义数组时出现错误

我在a reporter中的rails 4电子邮件迁移中使用了

t.text:emails，array:true，default:[]，null:false

。在这里，我用以下代码验证每个条目

  validates_each :emails do |record, attr, value|
    value.each do |email|
      record.errors.add attr, I18n.t('reporter.error.not_valid_email', email: email) if (email =~ EMAIL_VALIDATION_REGEXP) == nil
    end
  end

当我创建AM类的实例时，我得到了以下错误

  1) Reporter budget, receipt and member interaction testing the remaining_promise_for_whole_budget_title method for overview of all available budgets
     Failure/Error: @reporter = FactoryGirl.create(:reporter)
     NoMethodError:
       undefined method `each' for "[\"lkajsdf@gmail.com\"]":String
     # ./app/models/reporter.rb:6:in `block in <class:Reporter>'
     # /Users/malik/.rvm/gems/ruby-2.2.1@maalify/gems/activemodel-4.2.0/lib/active_model/validator.rb:179:in `call'

这是解决办法。让它在块中。

Stll获取

失败/错误：ap@reporter.valid？NoMethodError:未定义“[\”的方法“each”lkajsdf@gmail.com\“]”：字符串

FactoryGirl.define do
  factory :reporter do

    name "MyReport"
    donations %W(1 2)
    tanzeems "MyString"
    interval "28"
    emails ["lkajsdf@gmail.com"]
  end
end

FactoryGirl.define do
  factory :reporter do
