Rspec & ShouldaMatchers 与 class_name

Question

我收到以下错误：

1) Admin should belong to hospital
 Failure/Error: it {should belong_to(:hospital).with_foreign_key('medical_facility_id')  }
   Expected Admin to have a belongs_to association called hospital ()

与：

#admin_spec.rb
  it {should belong_to(:hospital).with_foreign_key('medical_facility_id')  }

型号是：

class Admin < ActiveRecord::Base
  belongs_to :hospital
end

class Hospital < MedicalFacility
end

在schema.rb中：

create_table "admins", force: :cascade do |t|
    t.integer  "user_id",             null: false
    t.string   "role",                null: false
    t.integer  "medical_facility_id"
    t.datetime "created_at",          null: false
    t.datetime "updated_at",          null: false
end

如何正确编写该模型的测试？也许我应该补充 `class_name:"MedicalFacility" 到 Admin 模型？

Answer 1

告诉 Rails 你的外键：

class Admin < ActiveRecord::Base
  belongs_to :hospital, foreign_key 'medical_facility_id'
end
