Question

我刚刚开始使用FactoryGirls用于Ruby和Rails，我不明白为什么当我尝试运行测试时FactoryGirl给我这个错误：

> Failures:

>   1) Staffroom should create a valid staffroom from factory girl
>      Failure/Error: staffroom.should be_valid
>      NoMethodError:

>        ./app/models/location.rb:83:in `location_lookup'

>        ./spec/models/staffroom_spec.rb:52:in `block (2 levels) in <top (required)>'
>        -e:1:in `<main>'

这是我在spec / models / staffroom_spec.rb中的代码：

describe Staffroom do
  it 'should create a valid staffroom from factory girl' do

    staffroom = build_stubbed(:group_staffroom)
    staffroom.should be_valid

    staffroom = build_stubbed(:industry_staffroom)
    staffroom.should be_valid

    staffroom = build_stubbed(:company_staffroom)
    staffroom.should be_valid
  end
end

我在spec / factories / staffrooms.rb中的代码：

FactoryGirl.define do
    factory :staffroom do

        name { Faker::Company.name }

        location 'NEW YORK, NY, 13123'

        factory :industry_staffroom do
            staffroom_type 'Industry'
        end

        factory :company_staffroom do
            staffroom_type 'Company'
        end

    end
end

我想我只是对于为什么FactoryGirl会在models / location.rb下查看？任何帮助将不胜感激。

编辑：这是location.rb第97行的代码：

94  def self.interpret_location_string(location_string)
95    not_defined_loc = Location.where(city: "SYDNEY*").first
96
97    unless not_defined_loc.location == location_string

感谢。

Answer 1

在构建Location.interpret_location_string时会调用

Staffroom，而第95行的查询似乎没有返回Location个对象。在访问其属性之前，您应该检查是否有对象。

FactoryGirls - NoMethodError：nil的未定义方法`location'：NilClass
