FactoryGirl - can't write unknown attribute, and undefined method `name'

I’m trying to create a photo factory that’s in a many to one association with gallery. And I’m getting two errors, depending on how I specify the association between those two models.

Here’s the models:

Photo

belongs_to :gallery, class_name: “SevenGallery::Gallery”

``

Gallery

has_many :photos, class_name: “SevenGallery::Photo”, foreign_key: “seven_gallery_gallery_id”, dependent: :destroy

``

And the migrations

create_table :seven_gallery_galleries do |t|
t.string :title
t.timestamps null: false
end

create_table :seven_gallery_photos do |t|
   t.string :caption
   t.string :image
   t.references :seven_gallery_gallery, index: true
   t.timestamps null: false
 end

 add_foreign_key :seven_gallery_photos, :seven_gallery_galleries, on_delete: :cascade

``

Now Here’s my factories:

Gallery:

FactoryGirl.define do
factory :gallery, class: ‘SevenGallery::Gallery’ do
title “an event gallery”
factory :gallery_with_photos do
after(:build) do |gallery|
gallery.photos << FactoryGirl.create(:photo_one, seven_gallery_gallery_id: gallery)
gallery.photos << FactoryGirl.create(:photo_two, seven_gallery_gallery_id: gallery)
gallery.photos << FactoryGirl.create(:photo_three, seven_gallery_gallery_id: gallery)
end
end
end
end

``

And Photo:

FactoryGirl.define do
factory :photo, class: “SevenGallery::Photo” do

 factory :photo_one do
 end

 factory :photo_two do
 end

 factory :photo_three do
 end

 factory :photo_with_gallery do
  gallery
 end
  end
end

``

And here’s the controller spec that generates the error:

it “changes is_main to true in self and false in rest” do
photo_one = FactoryGirl.create(:photo_with_gallery)
expect(photo_one.gallery).to be_a SevenGallery::Gallery
end

``

Whenever I run the test I get this error:

Failure/Error: photo_one = FactoryGirl.create(:photo_with_gallery)
ActiveModel::MissingAttributeError:
can’t write unknown attribute gallery_id
# ./spec/controllers/seven_gallery/photos_controller_spec.rb:

``

When I change the association part to be:

factory :photo_with_gallery do
association :gallery, factory: gallery
end

``

I get this error:

Failure/Error: photo_one = FactoryGirl.create(:photo_with_gallery)
NoMethodError:
undefined method `name’ for :photo_with_gallery:Symbol
# ./spec/controllers/seven_gallery/photos_controller_spec.rb:8

``

Any help would ne appreciated. Thanks.

I tried whipping up an app with your code, the controller test passes fine for me, see if it works for you and compare.

I can see the only difference is that in my case there’s namespace in front of the table names and FK. But in yours there’s none since it’s a normal app.
But is this the cause ?

In short, yes. See this lovely article; notice the conspicuous absence of any talk of changing table names:
http://blog.makandra.com/2014/12/organizing-large-rails-projects-with-namespaces/

Are you sure about this ? If so, is there a way to make it working without changing table names ?

you could try, in the model, self.table_name = “seven_gallery_photos” etc.

https://github.com/chrislerum/factory setting table_name seems to be the sweet spot, working now

This is really driving me insane. I’ve something very similar to your sample Here. I’ve specified table names inside models. But still the error occurs. Would you mind taking a look at it ? Thank you a lot so far for your time.
