ruby on rails - Factory Girl Nested Associations -


i have several rails models nested relationship using has_one through, , no matter how seem structure factorygirl factories can't relationship correctly setup.

models

class user < activerecord::base     has_one :subscription     has_one :plan, through: :subscription     has_one :usage_limit, through: :plan end  class subscription < activerecord::base     belongs_to :plan     belongs_to :user end  class plan < activerecord::base     has_many :subscriptions     belongs_to :usage_limit     has_many :users, through: :subscriptions end  class usagelimit < activerecord::base     has_one :plan end

no matter how structure factories, seem end users plan not being equal subscription plan, or can't setup usage_limit due "it goes through more 1 other association". i've tried using callbacks no luck, got idea how can factory these models , relationships?

factorygirl.define     factory :plan         name                    "test plan 1"         price                   19.99         active                  true         usage_limit     end   factorygirl.define     factory :subscription         active_subscription     true         on_trial_period         false         coupon_used             false         free_account            false         plan         user          after(:create) |s|             s.user.subscription = s             # s.user.plan = s.plan         end     end end  factorygirl.define     factory :usage_limit         keywords_per_month      2         discoveries_per_month   2         keywords_per_discovery  5     end end  factorygirl.define     factory :user         email                  "user@example.com"         password               "password"         password_confirmation  "password"         plan          after(:create) |user|           # user.subscription = factorygirl.build(:subscription, :user => user, :plan => user.plan)           # user.usage_limit = user.plan.usage_limit         end     end end

i'd able let!(:user) { factorygirl.build(:user) } , have of correct relationships created.

you need create instead of build. should work:

factorygirl.define   factory :user     after(:create) |user|       user.subscription = factorygirl.create(:subscription)     end   end    factory :plan     usage_limit   end    factory :subscription     plan   end    factory :usage_limit   end end  require 'rails_helper'  describe user   let(:user) { factorygirl.create(:user) }    "has subscription"     expect(user.subscription).to_not be_nil   end    "has plan"     expect(user.plan).to_not be_nil     expect(user.plan).to eq user.subscription.plan   end    "has usage limit"     expect(user.usage_limit).to_not be_nil     expect(user.usage_limit).to eq user.plan.usage_limit   end  end

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
