After chapter 7, 12 tests fail

[enilsen16]

After spending a few hours troubleshooting, I'm stuck. I followed along with the book except to change the class level embed: :ids to embed on association. I even tried cloning this repo down and I still have these errors. Am I missing something @kurenn?

[kurenn]

@enilsen16 can you give me more details about the rspec version you are running, I'm running specs from chapter 8 and they are running fine.

[enilsen16]

I'm using rspec 3.2.1. rspec 2.x.x was giving me errors and depreciations with rails 4.2.1.
I had similar issues using active_model_serializers 0.8.0 and rails 4.2.1.

my entire gemfile:

source 'https://rubygems.org'

gem 'active_model_serializers', git: 'https://github.com/rails-api/active_model_serializers.git'
gem 'coffee-rails', '~> 4.1.0'
gem 'compass-rails'
gem 'devise'
gem 'font-awesome-rails'
gem 'furatto'
gem 'jquery-rails'
gem 'rails', '4.2.1'
gem 'sabisu_rails', github: 'IcaliaLabs/sabisu-rails', branch: 'master'
gem 'sass-rails', '~> 5.0'
gem 'sdoc', '~> 0.4.0', group: :doc
gem 'simple_form'
gem 'uglifier', '>= 1.3.0'

group :development do
  gem 'sqlite3'
end

group :development, :test do
  gem 'byebug'
  gem 'factory_girl_rails'
  gem 'ffaker'
  gem 'spring'
  gem 'web-console', '~> 2.0'
end

group :test do
  gem 'rspec-collection_matchers'
  gem 'rspec-rails'
  gem 'shoulda-matchers'
end

The repository can be found here: https://github.com/enilsen16/rails-devise-api

Any idea what's up?

[kurenn]

I cannot reproduce the error, I cloned your repo and ran all the tests, and they all work. What are you doing exactly?

[enilsen16]

@kurenn Hmm... ok

git pull for the lastest code and then try. There should be 72 examples...

I really appreciate your help troubleshooting 😄

[kurenn]

Did it worked?

[enilsen16]

No I still have these errors. I'll run through chapter 7 again, just to make sure I did everything right.

[florentferry]

I reproduce the error with your cloned repo, and I have similar issue. If you change your active_model_serializers to 0.8.3, all tests are passing.

gem 'active_model_serializers', '0.8.3'

[kurenn]

@enilsen16 try @florentferry solution and let me know how it goes!

[enilsen16]

@florentferry @kurenn Is it a syntax issue then with 'active_model_serializers', '0.10.0'?

Now that I am using an older version everything passes.

[florentferry]

No, the problem comes from the gem itself and/or dependencies with Rails 4.2 and RSpec 3. I check in active_model_serializers and find 0.8.3 works well with this stack.

[pedrovcenteno]

Hi,
I'm not an expert but at GitHub's page for active_model_serializers says:

This [version 0.10.0] is not backward compatible with 0.9.0 or 0.8.0.

[pedrovcenteno]

I was having the same problems and after having changed active_model_serializers to 0.8.3, as your suggestion, solved them.

I has caused problems on PRAX too: its Linux process was crashing. It's ok now.

Having read the console RSpec's output of the tests, it seems the version of active_model_serializers I had before caused some infinite loop and crashed. The output, may it be important:

~/projects/marketplaceapi$ bundle exec rspec spec/controllers/api/v1/products_controller_spec.rb

I have exactly the same thing as @pedrovcenteno . Reading the DEPRECATION WARNING:
"The use of .embed method on a Serializer will be soon removed, as this should have a global scope and not a class scope."

I wonder then : does it still a good solution to use the embed ids and the old version of the gem or should we use something different such as the 'meta attribute' solution suggested by @kurenn in Box 7.2 ?

[kurenn]

@RobinCaroff I would say it's fine as long you don't update to version 0.10, otherwise it will cause problems.

It is a good solution, the only thing with version 0.10 is that uses the new JSON API standard http://jsonapi.org/ but at the end of the day you choose how you want to structure the JSON response.

[AdamYang121]

Hi, I just solve the problem, it's just the change of GET request syntax. You don't need rollback to old version active_model_serializers.
Try this:
get :show, params: { id: @product.id }
instead of
get :show, id: @product.id

Hope it is helpful. Good luck.

[kurenn]

@RobinCaroff can you try with @AdamYang121's solution?

[shogmar]

I was having the same problems and after having changed active_model_serializers to 0.8.3, as your suggestion, solved them. But I have a version of rails 6, ruby 2.6.5.

[kurenn]

@shogmar Were you able to keep moving forward?

[shogmar]

@shogmar Were you able to keep moving forward?

Yes, I changed the version to 0.8.3

[kurenn]

Glad to read it!
