FactoryGirl issues with associations in Rspec/Rails - ruby-on-rails

Question

Here is the method I am testing:
class User < ActiveRecord::Base
has_many :sports, :through => :user_sports, order: "user_sports.created_at", class_name: "Sport"
has_many :user_sports
def primary_sport
return nil if user_sports.blank?
user_sports.primary_only.first.sport
end
end
User Factory;
FactoryGirl.define do
sequence(:email) do |n|
"user#{n}#example.com"
end
factory :user do
email
first_name Faker::Name.first_name
last_name Faker::Name.last_name
password "password"
password_confirmation "password"
agreed_to_age_requirements true
username "testing123"
state "AL"
city_id 201
school_id 20935
handedness "Left"
customer_id { "#{rand(1000)}" }
sports {[create(:sport)]}
after(:create) do |user, elevator|
user.subscriptions << create(:subscription)
user.roles << create(:role)
end
end
factory :athlete, class: "Athlete", parent: :user do
type "Athlete"
recruit_year "2016"
end
end
Here is my test:
require 'spec_helper'
describe User do
describe "associations" do
it { should have_and_belong_to_many(:roles) }
it { should belong_to(:account_type) }
it { should belong_to(:primary_sport).class_name("Sport") }
it { should belong_to(:school) }
it { should belong_to(:city) }
it { should belong_to(:hometown) }
it { should have_many(:social_actions) }
it { should have_one(:invitation) }
it { should have_many(:authorizations) }
it { should belong_to(:user_type) }
it { should have_and_belong_to_many(:positions).class_name "SportPosition" }
it { should have_many(:sports).through(:user_sports) }
it { should have_many(:user_sports) }
it { should have_many :contributorships }
it { should have_many(:managed_athletes).through(:contributorships) }
it { should have_and_belong_to_many(:subscriptions) }
end
describe "nested attributes" do
it { should accept_nested_attributes_for(:user_sports) }
it { should accept_nested_attributes_for(:subscriptions) }
end
describe "validations" do
it { should validate_presence_of(:email) }
it { should validate_uniqueness_of(:email) }
it { should allow_value("test#test.com").for(:email) }
it { should_not allow_value("test.com").for(:email) }
end
describe "instance methods" do
before :each do
#user = create(:user, sports: [])
#school_admin_role = create(:role, name: "School Admin")
#contributor_role = create(:role, name: "Contributor")
end
describe "#my_athletes_path" do
it "returns a school admin path if the user has the role of School Admin" do
#user.roles << #school_admin_role
#user.my_athletes_path.should eq school_admin_athletes_path
end
it "returns a school admin path if the user has the role of Contributor" do
#user.roles << #contributor_role
#user.my_athletes_path.should eq contributor_dashboard_path
end
it "returns nil if the user has no Contributor or School Admin role" do
#user.my_athletes_path.should be_nil
end
end
describe "#first_time_login?" do
it "will evalute true if the user has logged in only once" do
#user.sign_in_count = 1
#user.save
#user.first_time_login?.should be_true
end
end
describe "#confirmation_required?" do
it "returns false" do
#user.confirmation_required?.should be_false
end
end
describe "#primary_sport", focus: true do
context "when user has no primary sport" do
it "returns nil" do
#user.primary_sport.should be_nil
end
end
context "when user has a primary sport" do
it "returns sport object" do
#user.sports << create(:sport)
#user.primary_sport.should eq #user.sports.first
end
end
end
end
end
This is the error I am receiving:
Failure/Error: #user.primary_sport.should eq #user.sports.first
NoMethodError:
undefined method sport for nil:NilClass
This is because when the user_sport association is created in the User Factory, the primary column is being set to false. Not sure how to fix this. Any help is greatly appreciated! Also, sorry for the ignorance on the TDD front, Im a newb

Answer 1

Couldn't you just add the following to your after(:create) block in the User factory:
us = user.user_sports.first
us.primary = true
us.save
That would ensure the association gets the primary flag.
