我正试图编写一个控制器规范，用于创建带有购买行项目的购买。使用我给它的所有属性创建了购买，但是没有创建购买行项目。下面是我的代码:
factories.rb
FactoryGirl.define do
factory :purchase do |f|
f.sequence(:po_number) { |n| "0000-00#{n}" }
f.sequence(:ship_to) { |n| "Test Corp#{n}"}
f.sequence(:ship_via) {|n| "Test Delivery#{n}" }
f.sequence(:terms) {|n| "My terms#{n}" }
f.sequence(:qa_requirements) {|n| "Requirment#{n}" }
f.sequence(:justification) {|n| "Justification#{n}" }
f.become_part_of_delivered_product true
f.immediately_delivered_to_stc_client false
f.remain_for_contract_at_stc_as_gov_prop false
f.consumed_in_job_requirements true
f.used_in_repair_of_gov_prop false
f.is_gov_prop_in_possession_of_stc false
f.sequence(:required) {|n| "2011-10-0#{n}" }
f.prd_number_id { |n| n.association(:prd_number).id }
# f.order_for_id { |o| o.association(:user) }
f.submitted_by_id { |s| s.association(:submitted_by).id }
# f.ordered_for_date { Time.now.to_s }
f.submitted_by_date { Time.now.to_s }
f.quality_system_classification_id { |q| q.association(:quality_system_classification).id }
f.after_create { |c| Factory(:purchase_line_item, purchase: c) }
end
factory :purchase_line_item do |f|
f.sequence(:item_description) {|n| "Desc#{n}" }
f.unit_price "100.00"
f.qty "40"
f.sequence(:charge_number) {|n| "000-00#{n}" }
end
end
PurchaseLineItem.rb
belongs_to :purchase
validates_presence_of :item_description,
:unit_price,
:qty,
:charge_number
Purchase.rb
belongs_to :authorized_signers
belongs_to :vendor
belongs_to :purchase_type
belongs_to :quality_system_classfication
belongs_to :order_by, :class_name => "User", :foreign_key => "order_by_id"
belongs_to :submitted_by, :class_name => "User", :foreign_key => "submitted_by_id"
belongs_to :approved_by, :class_name => "User", :foreign_key => "approved_by_id"
belongs_to :purchased_by, :class_name => "User", :foreign_key => "purchased_by_id"
has_many :purchase_line_items
has_many :audits
accepts_nested_attributes_for :purchase_line_items, :allow_destroy => true
validates_presence_of :required,
:ship_to,
:ship_via,
:terms,
:quality_system_classification_id,
:prd_number_id
购买控制器
load_and_authorize_resource
def new
@purchase = Purchase.new
1.times { @purchase.purchase_line_items.build }
end
def create
@purchase = Purchase.new(params[:purchase])
@purchase.without_auditing do
if @purchase.save
flash[:notice] = "Successfully created purchase."
redirect_to @purchase
else
render action: 'new'
end
end
end
PurchaseController规范
require 'spec_helper'
describe PurchasesController do
login_user
describe "POST create" do
before(:each) do
@ability.can :create, Purchase
end
it "should pass the params to purchase" do
purchase = Factory(:purchase)
post :create, purchase: purchase.attributes.except("id")
assigns(:purchase).po_number.should == purchase.po_number
end
it "should pass the params to purchase_line_items" do
purchase = Factory(:purchase)
post :create, purchase: purchase.attributes, purchase_line_items_attributes: purchase.purchase_line_items.first.attributes
assigns(:purchase).purchase_line_items.first.unit_price.should == purchase.unit_price
end
end
end
Thanks in advance
在Rails 4下，这种通用性不适合我:
post :create, purchase: { attributes: p, purchase_line_items_attributes: [pl] }
下面是我发现的一个通用的风格，可以满足这个职位:create…为Rails 4更新。注意:valid_session可能不完全像我存根一样工作，但是你得到了DRY的想法;)
describe PurchasesController do
def valid_session
controller.stub!(:authorize).and_return(User)
end
describe 'POST :create' do
before do
purchase = FactoryGirl.build(:purchase).attributes
purchase_line_item = { purchase_line_items_attributes: { "#{rand(903814893)}" => FactoryGirl.build(:purchase_line_item).attributes } }
@valid_attributes = purchase.merge(purchase_line_item)
end
context "with valid params" do
before(:each) do
post :create, { purchase: @valid_attributes }, valid_session
end
it "assigns a newly created purchase as @purchase" do
assigns(:purchase).should be_a(Purchase)
end
it "saves a newly created purchase" do
assigns(:purchase).should be_persisted
end
it "redirects to the created purchase" do
response.should redirect_to(Purchase.last)
end
end
context "with invalid params" do
before do
Purchase.any_instance.stub(:save).and_return(false)
post :create, { purchase: @valid_attributes }, valid_session
end
it "assigns a newly created but unsaved purchase as @purchase" do
assigns(:purchase).should be_a_new(Purchase)
end
it "re-renders the :new template" do
response.should render_template("new")
end
it "returns http success" do
response.should be_success
end
end
end
end
在Rails 4中，如果将控制器设置为使用:
params.require(:purchase).permit(...)
并从模型中删除attr_accessible，然后您不必担心使用attributes.except(...)进行过滤。
明白了。我改变了一些东西，但问题是语法。在PurchasesController Spec中，我将代码更改为:
describe PurchasesController do
login_user
render_views
before(:each) do
@purchase = Factory(:purchase)
end
describe "POST create" do
before(:each) do
@ability.can :create, Purchase
end
it "should pass the params to purchase" do
i = @purchase.id
p = @purchase.attributes.except('id', 'created_at', 'updated_at')
pl = @purchase.purchase_line_items.first.attributes.except('id', 'purchase_id', 'created_at', 'updated_at')
post :create, purchase: { attributes: p, purchase_line_items_attributes: [pl] }
assigns(:purchase).attributes.except('id', 'created_at', 'updated_at').should == p
assigns(:purchase).purchase_line_items.first.attributes.except('id', 'purchase_id', 'created_at', 'updated_at').should == pl
end
end
end
语法需要从:
post :create, purchase: purchase.attributes, purchase_line_items_attributes: purchase.purchase_line_items.first.attributes
:
post :create, purchase: { attributes: p, purchase_line_items_attributes: [pl] }
现在一切正常!
