Rails中的rspec模型测试：方法可行，但测试无法通过

Question

I have two models Indicator belongs_to Privacy.

In indicator I wrote a method to return the proper name of the privacy setting

def privacy
    Privacy.find(privacy_tag_id).content
end

That works in rails console. If I create an Indicator and then run Indicator.privacy I get back "red" or "green" or whatever. But I can't get my rspec to pass. Here is the test

describe "indicator" do
    it "should return a human named when asked for its privacy level" do
        @privacy = PrivacyTag.create(:content => "Secret")
        @ind = Indicator.new(:content => 'test',
                             :privacy_tag_id => @privacy.id)
        @ind.privacy.should == "Secret"
    end
end

When I run the test I get this message:

Failures:

  1) indicator should return a human named when asked for its privacy level
     Failure/Error: @ind.privacy.should_equal "Secret"
     ActiveRecord::RecordNotFound:
       Couldn't find PrivacyTag without an ID
     # ./app/models/indicator.rb:13:in `privacy'
     # ./spec/models/indicator_model_spec.rb:9:in `block (2 levels) in <top (required)>'

What am I doing wrong in my test? Any ideas?

Answer 1

I would suspect that the Privacy object isn't being created. Try calling create! instead of create . If it raises an exception, then that means that your Privacy model has some validations in it.

It would've been super helpful to have seen your models in the first place.
