我无法弄清楚如何修复RSpec错误。 我的应用是这样的。 有3个型号，CompanyBag，CompanyBagTarget，Company。 CompanyBag是一组公司。 CompanyBagTarget是CompanyBag和Company之间的关联表。 可能是，CompanyBagTarget与相应的公司不匹配。
现在，RSpec错误就在这里。
1) CompanyBagsController POST #create creates a new ComapnyBag
Failure/Error: t.save!

2) CompanyBagsController POST #create creates a new ComapnyBagTarget
Failure/Error: t.save!

接下来是模型的定义。
class CompanyBag < ApplicationRecord
has_many :targets, class_name: "CompanyBagTarget"
def update_targets!(company_ids:)
destroy_targets
company_ids.reverse.each_with_index do |id, idex|
t = CompanyBagTarget.new
t.company_bag_id = self.id
t.company_id = id
t.display_order = idex
t.save!
end
end
class CompanyBagTarget < ApplicationRecord
belongs_to :company_target
接下来，这是控制器。
def create
@bag = CompanyBag.new(bag_params)
@target_ids = params[:company_bag][:target_ids].split(",").map{|n| n.split("_")[0].to_i}
if bag_params[:banner].present?
filename = upload_image
@bag.banner = filename
end
if @bag.save
@bag.update_targets!(company_ids: @target_ids)
redirect_to action: 'index'
else
flash[:alert] = @bag.errors.messages.values[0][0]
@target_ids = params[:company_bag][:target_ids]
render 'new'
end
end
最后，这是控制器的规格。
require 'rails_helper'
RSpec.describe CompanyBagsController, type: :controller do
login_admin
let(:user) { @admin }
let(:company_bag) { FactoryGirl.create(:some_company_bag) }
let(:company_bag_target) { {target_ids: "1_インテリジェンステスト株式会社,21_>グローバルウォーカーズ株式会社,33_株式会社コーデセブン"} }
let(:companies) { FactoryGirl.create(:companies) }
let(:valid_attributes) {
{
label: 1,
banner: "https://s3-ap-northeast-1.amazonaws.com/eiicon.prd.contents/image/bags/6dbd5b5b-f242-4e4a-bcd3-de3edc9ae08d.png",
title: "test title",
description: "test title",
target_ids: "1_インテリジェンステスト株式会社,21_グローバルウォーカーズ株>式会社,33_株式会社コーデセブン"
}
}
describe 'POST #create' do
it 'creates a new ComapnyBag' do
expect{
post :create, params: {company_bag: valid_attributes}, session: valid_session
}.to change(CompanyBag, :count).by(1)
end
it 'creates a new ComapnyBagTarget' do
expect{
post :create, params: {company_bag: valid_attributes}, session: valid_session
}.to change(CompanyBagTarget, :count).by(1)
end
请任何人。提前谢谢。
[附录] 接下来，这是工厂。
FactoryGirl.define do
factory :some_company_bag, class: CompanyBag do
label "some label"
banner "https://s3-ap-northeast-1.amazonaws.com/eiicon.prd.contents/image/bags/6dbd5b5b-f242-4e4a-bcd3-de3edc9ae08d.png"
title "Best Company Title Ever!!"
description "Some says description"
html_description "Html desc"
html_keyword "Html Kw"
end
factory :companies, class: Company do
name "複数テスト会社"
name_kana "フクスウテストカイシャ"
premium_status "free"
pr_status_id 0
is_valid 1
after(:create) do |c|
c.staff << FactoryGirl.create(:staff, company_id: c.id)
end
end
end
表格。
create_table "company_bag_targets", primary_key: ["company_bag_id", "company_id"], force: :cascade, options: "ENGINE=InnoDB DEFAULT CHARSET=utf8mb4" do |t|
t.integer "company_bag_id", null: false
