Devise.stub(:friendly_token).and_return("auniquetoken123") warning

I'm getting this warning for the line above in user_spec.rb:
Using stub from rspec-mocks' old :should syntax without explicitly enabling the syntax is deprecated ...

How can I get rid of it?

Thanks

Making an API request from outside sabisu

I've used your app to make similar API for myself. Thank you! It looks very promising.

If I am trying to make a request to the API outside of sabisu what URL should I hit? I've deployed my application using AWS and can make requests through sabisu just fine. When I'm trying to make a request from somewhere else though I don't know what URL to make it through to just get JSON responses.

Finished chapter 9 - Don't know how to generate correct URL so see user's order

I am using this URL which is probably not the correct one since is not including authorizatio.
Don't know how to generate the right one:

http://api.marketplaceapi.dev/users/1/orders

{"errors":"Not authenticated"}

Finished chapter 9 - How API explorer can be used to see orders?

I am trying an URL similar to that used for Products:
http://localhost:3000/sabisu_rails/explorer?explorer%5Bresource%5D=orders
The error I am getting is: NoMethodError in SabisuRails::Explorer#index
Showing .../sabisu_rails/explorer/index.html.erb where line #36 raised:

undefined method `attributes' for #<EnoughProductsValidator:0x007ffe5da72930 @options={}>
def required_attributes
@required_attributes ||= resource_class.validators.map(&:attributes).flatten.uniq
end

Use SSL for sabisu-rails

I'd recommend using:

'sabisu_rails', git: "https://github.com/icaliaLabs/sabisu-rails"

NameError in SabisuRails::Explorer#index

Not sure if this issue should be opened within here or SabisuRails:

During the course of the book, after I do this step within sabisu_rails.rb:

config.base_api_uri = "api.marketplace.dev"

I get the following error when I visit http://localhost:3000/sabisu_rails/explorer :

I do not see the API Explorer in Figure 3.2.

Here is my gemfile setup:

Chapter 9.1.1 : Extending the Placement model

In Chapter 9.1.1 : Extending the Placement model, we should extend the Placement model with a decrement_product_quantity! but we can't commit our changes without testing before, but test fails.

require 'spec_helper'

describe Placement do
  .
  .
  .
  it { should respond_to :quantity }
  .
  .
  .
  describe "#decrement_product_quantity!" do
    it "decreases the product quantity by the placement quantity" do
      product = placement.product # placement doesn't have a product
      expect{placement.decrement_product_quantity!}.to change{product.quantity}.by(-placement.quantity)
    end
  end
end

product is nil because we don't set a product to placement so launching the test complains about undefined method 'quantity' for nil:NilClass.

In Chapter 8 : Listing 8.4, we write this Placement specs :

require 'spec_helper'

describe Placement do
  let(:placement) { FactoryGirl.build :placement }
  subject { placement }

  it { should respond_to :order_id }
  it { should respond_to :product_id }

  it { should belong_to :order }
  it { should belong_to :product }
end

We don't touch at this spec before Listing 9.2. So placement doesn't receive a product.

Solution

describe Placement do
 let(:product) { FactoryGirl.create(:product, quantity: 4) }
 let(:placement) { FactoryGirl.create(:placement, product_id: product.id, quantity: 2) }
end

Now, product is define. It responds to quantity. And test pass.

Solution 2

Modify the factory placement works too. When we generate the model, the factory placement generated by FactoryGirl sets to nil each attribute.

FactoryGirl.define do
 factory :placement do
  order
  product
  quantity 1
 end
end

Sabisu Rails Browser Interface - how can be used to create, update, delete user

I am at the end of chapter 6. Everything works well, all tests are green. Here is the question. How I can use the Sabisu browser interface http://localhost:3000/sabisu_rails/explorer to delete, or update, or create an user? Im selecting DELETE instead of GET, I am entering the user id 2 and press Enter and no user is deleted. Also I am getting the message:
{
"errors": "Not authenticated"
}

undefined method `valid_password?' for false:FalseClass

When using postman to create a session, I'm getting undefined methodvalid_password?' for false:FalseClass`.

Here is my sessions_controller.rb

class Api::V1::SessionsController < ApplicationController
  respond_to :json

  def create
    user_password = params[:session][:password]
    user_email = params[:session][:email]
    user = user_email.present? && User.find_by(email: user_email)

    if user.valid_password? user_password
      sign_in user, store: false
      user.generate_authentication_token!
      user.save
      render json: user, status: 200, location: [:api, user]
    else
      render json: { errors: 'Invalid email or password' }, status: 422
    end
  end

  def destroy
    user = User.find_by(auth_token: params[:id])
    user.generate_authentication_token!
    user.save
    head 204
  end

end

After adding embed :ids to user_serializer.rb

class UserSerializer < ActiveModel::Serializer
embed :ids
attributes :id, :email, :created_at, :updated_at, :auth_token

has_many :products
end

Two problems arise. the depreciated embed ids attribute is causing 10 test related to the user model to fail

DEPRECATION WARNING: ** Notice: embed is deprecated. **
The use of .embed method on a Serializer will be soon removed, as this should have a global scope and not a class scope.
Please use the global .setup method instead:
ActiveModel::Serializer.setup do |config|

end

Showing full backtrace because every line was filtered out.
See docs for RSpec::Configuration#backtrace_exclusion_patterns and
RSpec::Configuration#backtrace_inclusion_patterns for more information.

I created a active_model_serializers.rb with the configuration included, but it didn't make a difference.

After chapter 7, 12 tests fail

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?

Chapter 3: Undefined mixing display-flex

Hi kurenn, i am following your APIs on Rails tutorial, and when i try to get sabisu-rails index view, i get a undefined mixing 'display-flex' error, reading your past answers, changed the version of compass-rails to 1.1.7 and now it works, so i suggest to include that on your book because now the version installed if we don't especify it is the 2.0.0 and this generates the error

Put/Patch #Update - Chapter 3 #28

I'm using rails 4.2 ruby 2.2 & mongoid and encountering a strange error when following your tutorial - section 3.2.3 (Updating users - I use recruiter class instead).

It looks like it failed to update email however it passed when I tweak it to update other information such as first name (see the screenshot).

Below are my API controller & Routes

Any thoughts & suggestions will be very appreciated!!!

Don't set the user_id manually

In Chapter 6, you set the user_id manually.

 post :create, { user_id: user.id, product: @product_attributes }

This should automatically be set using the current_user attribute in the controller.

respond_with error

Chapter 7 - Show code changes to users_controller_spec.rb file when serializing

It would be nice to see at a quick glance what changes to the users_controller_spec.rb were made at the start of Chapter Seven. However, you do get a better understanding of the code by needing to closely compare the code in chapter seven to that in chapter six.

404 error with sending a request to API

I have been successful to send a POST from my test iOS app to the Session controller and able to get the Authorization in return. However, I have been running into issue when sending a GET method to my Rails API. The routing seems not to be an issue as it works with cURL and Postman.

undefined method `stub' for Authenticable - Chapter 5.

chapter 3 : Error Api Routing

when i'm trying to access sabisu_rails/explorer, i had this error
Connection refused - connect(2) for "api.marketplaceapi.dev" port 80

i had move the project market_place_api to marketplaceapi folder. But the error is keep coming.

What we really testing in this piece of code?

I really don't understand the meaning of this code.

Listing 5.11: Authenticable authenticate with token method (spec/controllers/concerns/authenticable_spec.rb)

describe Authenticable do
  .
  .
  .
  describe "#authenticate_with_token" do
    before do
      @user = FactoryGirl.create :user
      authentication.stub(:current_user).and_return(nil)
      response.stub(:response_code).and_return(401)
      response.stub(:body).and_return({"errors" => "Not authenticated"}.to_json)

      expect(json_response[:errors]).to eql "Not authenticated"
    end

    it {  should respond_with 401 }
  end
end

Explain, please:

1. Why we don't ever call our testable method #authenticate_with_token ?
2. As I understand, we only stubbing response object and check if stubbing was made perfecty? What is the sense?
3. If I change this line

authentication.stub(:current_user).and_return(nil)

into this

authentication.stub(:current_user).and_return(@user)

all tests also should be passing. WTF?

Thanks.

some small flaws in the text

API requires CORS?

Hi,
I finished the whole way of this tutorial and now I'm trying to use it.

For the moment, and although all specs were successful, in Sabisu Explorer I just can use some simple GET ops for users (users/:id; users/orders;products;products/:id). Postman does not work at all (why?) No POST is allowed.

I'm not being able to create new users (which only requires email and password) and so I cannot get the session code to access the API funcs.

I'm building a Ember UI and it fails to. The errors are explicit relating XMLHttpRequest : No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access. The response had HTTP status code 404.
After some research on the web, I made the conclusion that I'm facing a CORS related issue.

What is the role of the API here? How can it handle this requirement?

Does anyone have similar problems?

ch6: 20.times { FactoryGirl.create :product }

Hi, I reached the end of Chapter 6, everything went well up to the point to fill DB with products with
20.times { FactoryGirl.create :product }
I'm getting an error as below

I did:
change gemfile to have factory_girl_rails and ffaker in :development, then
bundle install, then
20.times { FactoryGirl.create :product }

I got:

2.2.0 :001 > 20.times { FactoryGirl.create :product }
(0.2ms) begin transaction
User Exists (0.3ms) SELECT 1 AS one FROM "users" WHERE "users"."auth_token" = '' LIMIT 1
User Exists (0.2ms) SELECT 1 AS one FROM "users" WHERE "users"."email" = '[email protected]' LIMIT 1
(0.1ms) rollback transaction
ActiveRecord::RecordInvalid: Validation failed: Auth token has already been taken

Can anyone help here,please?

Pedro

When trying to run the tests, invalid option: --no-fail-fast

I cloned the project, run bundle install and as I say in the title, can't run the tests:

$ bundle exec rspec
invalid option: --no-fail-fast

Please use --help for a listing of valid options

Any idea why?

Chapter 6 - Included Controller code in Spec

Listing 6.16

The destroy spec code is missing.

You have a code snippet (see below) for spec/controllers/api/v1/products_controller.rb but I'm guessing you mean controllers/api/v1/products_controller.rb.

Hence, the (1) destroy spec needs to be added to chapter 6 and the (2) controller code snippet needs to be retitled from spec to app.

def destroy
  product = current_user.products.find(params[:id])
  product.destroy
  head 204
end

Quick note: I'm curious if you recommend adding a failing test to the destroy spec (see below):

describe "DELETE #destroy" do
  before(:each) do
    @user = FactoryGirl.create :user
    @product = FactoryGirl.create :product, user: @user
    api_authorization_header @user.auth_token 
    delete :destroy, { user_id: @user.id, id: @product.id }
  end

  it { should respond_with 204 }
end

And add the related code in the controller so that it gives a 422 if it's unable to destroy a resource.

if @product.destroy
   render nothing: true, status: 204
else
  render json: @product.errors, status: 422
end

Security about auth_token attribute

How do I send the auth_token only on SessionsController requests? Do I need to cread a User Serializer specifically for SessionsController?

Chapter 3: uninitialized constant ApiConstraints (NameError)

Hello,

After bundle install, and then doing rails g devise:install, i get this error (screenshot attached)
Do you know why this would be happening?

How to set up headers for a GET or POST authenticated request?

This is more of a question out of ignorance, but if I have a before_action :authenticate_with_token! on this project, can someone tell me how I'd properly set up the headers in sabisu or curl to have GET or POST request that works?

I have tried the header:
Authorization : key

And that doesn't seem to be enough. Thanks so much!

Test cases failing

def current_user
@current_user ||= User.find_by(auth_token: request.headers['Authorization'])
end

when i check, request.headers['Authorization'] equals null and all my test cases fail. What am I doing wrong?

I don't know if I'm missing something. I have triple checked the code compared to the guide. My repo is at https://github.com/jorgemoya/achiever_api/tree/698dd4adc31f65b3d9cce48fdbd1d9ff546303d8.

Chapter 6 - Rspec-rails should be "group :development, :test"

In the end of Chapter 6, the 'rspec-rails' gem is in "group :test". I'd recommend adding it to "group :development, :test" so that it works for rake tasks and generators.

See: https://github.com/rspec/rspec-rails#installation

Chap 6: no implicit conversion of Symbol into Integer

The products_controller_spec.rb (I used different class name: event) failed with the error below.
no implicit conversion of Symbol into Integer

accessing the api

not sure if this is the right place for this, but I'm having an issue. everything is done, tests are passing, and i deployed it to heroku. When it's actually on production, what would the address be? according to the development structure of accessing the app via http://api.repo_name.dev/, the heroku equivalent should be https://api.heroku_name.herokuapp.com right?

On development, if I go into my browser and type http://api.marketplaceapi.dev/products i get a json response. However if I make a curl request to https://api.heroku_name.herokuapp.com/products I get Heroku | No such app.

with the api subdomain set, would you know how to go about accessing the endpoints in production?

I found the solution here:
http://stackoverflow.com/questions/28786439/undefined-method-response-for-nilnilclass-rspec-test

and the solution is to had:
subject { authentication }

as below:
...
let(:authentication) { Authentication.new }
subject { authentication }
describe '#current_user' do
...

This solved my problem (why is something I cannot say at this moment...)
