我正在尝试运行非常基本的规格测试,但测试失败,并显示错误“名称已被占用”。
更新属于具有许多角色的用户。
用户模型
# == Schema Information
#
# Table name: users
#
# id :integer not null, primary key
# email :string default(""), not null
#
FactoryGirl.define do
factory :user_engineer, class: User do
id 1
email '[email protected]'
roles {[FactoryGirl.create(:engineer)]}
end
end
角色模型
# == Schema Information
#
# Table name: roles
#
# id :integer not null, primary key
# name :string
# description :text
#
FactoryGirl.define do
factory :engineer, class: Role do
id 3
name 'Engineer'
description 'He is the chosen one'
end
end
更新模型
# == Schema Information
#
# Table name: updates
#
# id :integer not null, primary key
# content :text
# user_id :integer
# ticket_id :integer
#
FactoryGirl.define do
factory :update do
content "This is a test update"
association :user, factory: :user_engineer
end
end
update_spec.rb
require 'rails_helper'
RSpec.describe Update, type: :model do
let(:update){ FactoryGirl.create :update }
it { expect(update).to be_valid }
end
这是错误:
Update
example at ./spec/models/update_spec.rb:19 (FAILED - 1)
Failures:
1) Update
Failure/Error: roles {[FactoryGirl.create(:engineer)]}
ActiveRecord::RecordInvalid:
Validation failed: Name has already been taken
我如何通过测试?
编辑:通过添加建议的序列行,运行后出现以下错误RAILS_ENV=test rake db:drop
:
1) Update
Failure/Error: roles {[FactoryGirl.create(:engineer)]}
ActiveRecord::RecordNotUnique:
PG::UniqueViolation: ERROR: duplicate key value violates unique constraint "roles_pkey"
DETAIL: Key (id)=(3) already exists.
: INSERT INTO "roles" ("id", "name", "description", "created_at", "updated_at") VALUES ($1, $2, $3, $4, $5) RETURNING "id"
从错误中可以很明显地看出,您对属性进行了uniq验证name
,因此应该使用sequence
技术。
FactoryGirl.define do
factory :engineer, class: Role do
id 3
sequence(:name) { |n| "Engineer-#{n}" }
description 'He is the chosen one'
end
end
