我有一个同时使用关联和枚举属性的模型。
class ProjectItem < ActiveRecord::Base
belongs_to :project
enum status: {open: 0, pending: 1, completed: 2}
当我对具有关联的模型的创建操作运行测试时,我使用build(:model_name).attributes
,如下所示:
it "creates a new ProjectItem" do
expect {
post :create, document_project_item: build(:project_item).attributes
}.to change(ProjectItem, :count).by(1)
end
这是失败的,我找到了this issue thread that explains why it doesn't work。根据评论,我能够确定在具有enum
属性但没有关联的表格上,按预期方式使用attributes_for(:model_name)
。
问题主题似乎没有建议解决方法,但我承认我不了解FactoryGirl方法在幕后所做的100%。这是工厂:
factory :project_item do
project
name { Faker::Company.bs }
description { Faker::Lorem.paragraph }
status :open
due { Faker::Date.between(2.days.ago, 10.days.from_now) }
sequence(:position) {|n| n }
completed_at { Faker::Date.between(1.year.ago, Date.today) }
end
我也尝试在status
中放入一个整数,但我得到了同样的错误:
Failure/Error: post :create, project_item: build(:project_item).attributes
ArgumentError:
'0' is not a valid status
答案 0 :(得分:1)
我对其他解决方案持开放态度,但这是我提出的解决方法。
let(:project_attributes) { build(:project_item).attributes.merge(status: 'pending') }
it "creates a new ProjectItem" do
expect {
post :create, project_id: project.id, project_item: project_attributes
}.to change(ProjectItem, :count).by(1)
end
答案 1 :(得分:0)
必须在现有工厂调用中添加.merge
是一场噩梦。
您在工厂需要的是
status 'open'
