对 ruby、rails 和单元测试来说非常新，所以欢迎任何额外的反馈！
我正在为名为#assign_campaign 的基于 ActiveRecord 的模型（联系人）编写 rspec 单元测试。ContactCampaign 是将联系人映射到营销活动的关联。这里的想法是，当一个活动被分配时，该联系人的所有其他活动都会被停用，分配的活动会被激活。
测试失败，因为它声称已分配活动的状态为 nil 且不是“活动”（或“非活动”）。
似乎归结为，在campaign_id 属性上匹配的“where”似乎不会返回相同的对象，就像我遍历contact_campaigns 并在campaign_id 上进行匹配一样。
例如
contact.contact_campaigns.where(campaign_id: campaign_to_be_assigned.id).first.inspect
得到我：
<ContactCampaign id：6，contact_id：1，campaign_id：1，状态：nil，created_at：“2013-09-11 23:40:07”，updated_at：“2013-09-11 23:40:07”，current_position： 1>
object_id 为：70199917191760
尽管
contact.contact_campaigns.each do |x|
if x.campaign_id == campaign_to_be_assigned.id
puts x.inspect
end
end
得到我：
<ContactCampaign id：6，contact_id：1，campaign_id：1，状态：“活动”，created_at：“2013-09-11 23:40:07”，updated_at：“2013-09-11 23:40:08”，当前位置：1>
object_id 为：70199940110940
这里发生了什么？这是 ActiveRecord 失败、FactoryGirl 失败还是简单的 Ruby 失败？;p
如果我从以下位置重写assign_campaign：
current_contact_campaign = contact_campaigns.where(campaign_id: campaign_id).first
current_contact_campaign.activate
current_contact_campaign.set_current_position(starting_position) unless
starting_position == 0
至：
contact_campaigns.each do |x|
if x.campaign_id == campaign_id
x.activate
x.set_current_position(starting_position) unless
starting_position == 0
end
end
然后一切都很开心，但我想知道发生了什么。
Rspec 测试：
it "assign_campaign assigns a campaign, creates a new campaign task,
note and deactivates other contact campaigns, one was active previously" do
# not checking the note portion right now
contact = FactoryGirl.create(:contact, user: user)
campaign_to_be_assigned = FactoryGirl.create(:campaign)
campaign_to_be_assigned.messages << FactoryGirl.create(:message)
5.times do |i|
contact.campaigns << FactoryGirl.create(:campaign)
end
contact.deactivate_contact_campaigns
# Randomly activates one of the generated campaigns
contact.contact_campaigns[rand(4)].activate
contact.assign_campaign(campaign_to_be_assigned.id)
contact.contact_campaigns.each do |x|
if x.campaign_id == campaign_to_be_assigned.id
x.status.should == 'active'
else
x.status.should == 'inactive'
end
end
end
正在测试的方法：
def assign_campaign(campaign_id=nil, starting_position = 0, opts = {})
if email_is_valid || campaign_id == nil
if !campaign_id.blank?
campaign = Campaign.find(campaign_id)
deactivate_contact_campaigns
campaigns << campaign if !campaigns.include? campaign
current_contact_campaign = contact_campaigns.where(campaign_id: campaign_id).first
current_contact_campaign.activate
current_contact_campaign.set_current_position(starting_position) unless
starting_position == 0
notes.create(user_id: user.id, body: "Assigned #{name} to " +
campaign.description, group: "system",
created_at: (opts[:assign_time] ? opts[:assign_time] : Time.now))
create_new_campaign_task(opts[:user_id],
(starting_position == 0 ? 0 : (starting_position - 1)))
return true
else
notes.create(user_id: user.id,
body: "Unassigned #{name} from campaign", group: "system",
created_at: (opts[:assign_time] ? opts[:assign_time] : Time.now)) if
contact_campaigns.where(status: 'active').size > 0
deactivate_contact_campaigns
end
else
return false
end
end
