Factory Girl and has_one

Here's my models :

Class Audition
  belongs_to :video
end

Class Video
  has_one :audition
end

and my factories :

Factory.define :video do |v|
  v.filename  {Sham.filename}
 开发者_StackOverflow v.video_url {Sham.url}
end

Factory.define :audition do |a|
  a.video     {|a| a.association(:video)}
  a.label     {Sham.label}
end

How could I create a video factory that have an audition,

I mean, be able to :

v = Factory.create(:video)
v.audition # I'd like this to be not nil !

Because I have an observer on my video that try to access the audition from the video object

I tried several things but I always end with a stack level too deep or audition nil.

Do you have an idea ?

Thanks, Mike

If that's the case I would add the association into the other factory:

Factory.define :video do |v|
  v.filename                        {Sham.filename}
  v.video_url                       {Sham.url}
  v.audition                        {|v| v.association(:audition)}
end

Then you can do

v = Factory(:video) # This will now have an audition
a = v.audition # This should not be nil

and

a = Factory(:audition) # An audition without a video, if that's possible?

You can also override any association as needed when you create the factory in your tests, i.e:

v = Factory(:video, :audition => Factory(:audition))
v = Factory(:video, :audition => nil)

Hope what I've said makes sense and is true lol. Let us know how you get on.

In 2020 the answer is to use traits with after create actions on one of the factories, e.g.

    trait :with_audition do
      after :create do |video|
        create(:audition, video: video)
      end
    end
