Estes são os arquivos principais do projeto em ruby on rails:
 
routes.rb:
 
Rails.application.routes.draw do root to: 'recipes#index' resources :recipes resources :recipe_types end  
recipe_type.rb:
 
class RecipeType < ApplicationRecord has_many :recipes end recipe.rb:
 
class Recipe < ApplicationRecord validates :title, :recipe_type, :cuisine, :difficulty, :cook_time, :ingredients, :cook_method, presence: true belongs_to :recipe_type def cook_time_min "#{cook_time} minutos" end end  
create_recipes.rb:

Passo o seguinte comando rspec especificamente em visitor_visit_homepage_spec.rb linha 11:
 
:~/workspace/cookbook_parte7$ rspec ./spec/features/visitor_visit_homepage_spec.rb:11 Run options: include {:locations=>{"./spec/features/visitor_visit_homepage_spec.rb"=>[11]}} Visitor visit homepage and view recipe (FAILED - 1) Failures: 1) Visitor visit homepage and view recipe Failure/Error: recipe = Recipe.create(title: 'Bolo de cenoura', difficulty: 'Médio', recipe_type: recipe_type, cuisine: 'Brasileira', cook_time: 50, ingredients: 'Farinha, açucar, cenoura', cook_method: 'Cozinhe a cenoura, corte em pedaços pequenos, misture com o restante dos ingredientes') ActiveModel::MissingAttributeError: can't write unknown attribute `recipe_type_id` # ./spec/features/visitor_visit_homepage_spec.rb:14:in `block (2 levels) in <top (required)>' Finished in 0.04808 seconds (files took 1.72 seconds to load) 1 example, 1 failure Failed examples: rspec ./spec/features/visitor_visit_homepage_spec.rb:11 # Visitor visit homepage and view recipe   E depois de fazer as mudanças nos arquivos recipe.rb e create_recipe.rb, executei o seguinte comando novamente:
$ rails db:migrate RAILS_ENV=test
 
Ao baixar o repositório na máquina, dei os seguintes comandos:
 
$ rails generate migration RemoveRecipe_typeToRecipe recipe_type:string
$ rails db:migrate RAILSENV=test
$ rails generate model recipe_type name:string
$ rails db:migrate RAILS_ENV=test
 
Modifiquei os arquivos recipetype.rb e createrecipe_type.rb conforme mencionado acima e passei o mesmo rails db:migrate mencionado.
 
Não estou entendendo o por que do erro, os relacionamentos entre as tabelas não estão feitos?
 
Estou partipando do processo seletivo da Locaweb, e faltam 4 desafios para concluir a entrega dos desafios e o prazo vai até 28/10/2019.
 
Aguardo por um comentário, dica ou sugestão.
 
Obrigado,
 
Marcelino
 

Configuro a pasta do projeto da seguinte forma:

Por favor, preciso de ajuda da comunidade Ruby. Sou recém chegado na linguagem Ruby e no framework Rails. Estou participando da Campus Code e não consigo progredir em um desafio proposto no treinamento. O repositório do projeto baixei em minha máquina virtual VMware com Ubuntu 18.04 e nele consta o projeto em Ruby on Rails e os testes para passar com rspec. Eis os arquivos sensíveis para concluir o projeto: 
 
home_controller.rb:
class HomeController < ApplicationController def page @recipes = Recipe.all end end page.html.erb:
<% if recipes == [] %> <h1>CookBook</h1> <p>Bem-vindo ao maior livro de receitas online</p> <% else %> <% @recipes.each do |recipe| %> <h1><%= recipe.title %></h1> <li><%= recipe.recipe_type %></li> <li><%= recipe.cuisine %></li> <li><%= recipe.difficulty %></li> <li><%= recipe.cook_time %> minutos</li> <% end %> <% end %> recipe.rb:
class Recipe < ApplicationRecord end routes.rb:
Rails.application.routes.draw do root to: 'home#page' resources :recipe end  
E esse é o arquivo de testes visitor_visit_homepage_spec.rb:
