我对 GraphQL 和 Apollo 非常陌生，我不明白下面的“aliasEmail”字段有什么问题。当我将此添加到查询时，我收到此错误消息。当我从查询中删除它时，一切正常。它在 'types.graphql' 中有很好的定义，只是一个简单的字符串字段。

error: Error writing result to store for query:
  query getCompanyForAliasEmailEditForm($companyId: ID) {

      aliasEmail
      telMobile

}

我对测试 (Rspec) 模型与 null: false 在某些属性上感到困惑：

当使用这些属性之一创建新实例时，新的 instance.valid? 返回 true 但如果我尝试保存它，它会在 ActiveRecord::NotNullViolation 上返回错误消息。我知道它通过了“模型验证”，但在“数据库验证”中失败。那么测试我的模型的正确方法是什么？

RSpec.describe BusinessSetting, type: :model do
  # before :each do
  #   @business_setting = FactoryGirl.create(:business_setting)
  # end

  it "has a valid factory" do
    expect(FactoryGirl.create(:business_setting)).to be_valid
  end

  it "is invalid without a business_id" do
    expect(FactoryGirl.create(:business_setting, business_id: 
nil)).not_to be_valid
  end 

  it "is invalid without a bot_token" do
    expect(FactoryGirl.build(:business_setting, bot_token: nil)).to 
raise_error
  end  
end

Failures:

  1) BusinessSetting is invalid without a business_id

Failure/Error: expect(FactoryGirl.create(:business_setting, business_id: nil)).to raise_error

 ActiveRecord::NotNullViolation:
   Mysql2::Error: Field 'business_id' doesn't …

它必须非常简单,但我无法弄清楚这个"$"究竟是什么意思.谢谢
