[英]Rails SystemStackError (stack level too deep) in actionpack
[英]Rails SystemStackError: stack level too deep
我正在測試我的應用程序(Rails 5)與rspec capybara和工廠女孩我有以下錯誤...我不知道發生了什么...我是非常新的rspec我希望你能幫助我:)謝謝你
Randomized with seed 41137
An error occurred in a `before(:suite)` hook.
Failure/Error: FactoryGirl.lint
SystemStackError:
stack level too deep
你會在下面找到我的代碼:
factories.rb
FactoryGirl.define do
factory :event do
name {Faker::Friends.character}
total_price 50
participant
end
factory :participant do
first_name { Faker::Name.first_name }
salary 900
event
end
end
event.rb
class Event < ApplicationRecord
has_many :participants, inverse_of: :event
validates :participants, presence: true
validates :name, presence: true, length: {minimum: 2}
validates :total_price, presence: true
accepts_nested_attributes_for :participants, reject_if: :all_blank, allow_destroy: true
def total_salary
all_salary = []
participants.each do |participant|
all_salary << participant.salary
end
return @total_salary = all_salary.inject(0,:+)
end
end
event_spec.rb
require 'rails_helper'
describe Event do
it { should have_many(:participants) }
it { should validate_presence_of(:participants) }
it { should validate_presence_of(:name) }
it { should validate_presence_of(:total_price) }
describe "#total_salary" do
it "should return the total salary of the participants" do
partcipant_1 = create(:participant, salary: 2000)
partcipant_2 = create(:participant, salary: 3000)
expect(partcipant_1.salary + partcipant_2.salary).to eq(5000)
end
end
end
在我的參與者模型中,我必須添加optional: true
belongs_to :event, option: true
所以fabriciofreitag建議很好:)
我們來看看你的工廠:
FactoryGirl.define do
factory :event do
name {Faker::Friends.character}
total_price 50
participant
end
factory :participant do
first_name { Faker::Name.first_name }
salary 900
event
end
end
在這種情況下,事件的創建將創建一個參與者,該參與者將創建一個將創建參與者的事件。 等等,在無限循環中(堆棧級別太深)。
也許你可以把它改成這樣的東西:
FactoryGirl.define do
factory :event do
name {Faker::Friends.character}
total_price 50
participants { create_list(:participant, 3, event: self) }
end
factory :participant do
first_name { Faker::Name.first_name }
salary 900
end
end
