ActionView::Template::Error: undefined local variable or method `recipes'

Recommended Posts

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:

 

require 'rails_helper'

feature 'Visitor visit homepage' do
  scenario 'successfully' do
    visit root_path

    expect(page).to have_css('h1', text: 'CookBook')
    expect(page).to have_css('p', text: 'Bem-vindo ao maior livro de receitas'\
                                        ' online')
  end

  scenario 'and view recipe' do
    #cria os dados necessários
    recipe = Recipe.create(title: 'Bolo de cenoura', recipe_type: 'Sobremesa',
                           cuisine: 'Brasileira', difficulty: 'Médio',
                           cook_time: 60)

    # simula a ação do usuário
    visit root_path

    # expectativas do usuário após a ação
    expect(page).to have_css('h1', text: recipe.title)
    expect(page).to have_css('li', text: recipe.recipe_type)
    expect(page).to have_css('li', text: recipe.cuisine)
    expect(page).to have_css('li', text: recipe.difficulty)
    expect(page).to have_css('li', text: "#{recipe.cook_time} minutos")
  end

  scenario 'and view recipes list' do
    #cria os dados necessários
    recipe = Recipe.create(title: 'Bolo de cenoura', recipe_type: 'Sobremesa',
                           cuisine: 'Brasileira', difficulty: 'Médio',
                           cook_time: 60)

    another_recipe = Recipe.create(title: 'Feijoada',
                                   recipe_type: 'Prato Principal',
                                   cuisine: 'Brasileira', difficulty: 'Difícil',
                                   cook_time: 90)

    # simula a ação do usuário
    visit root_path

    # expectativas do usuário após a ação
    expect(page).to have_css('h1', text: recipe.title)
    expect(page).to have_css('li', text: recipe.recipe_type)
    expect(page).to have_css('li', text: recipe.cuisine)
    expect(page).to have_css('li', text: recipe.difficulty)
    expect(page).to have_css('li', text: "#{recipe.cook_time} minutos")

    expect(page).to have_css('h1', text: another_recipe.title)
    expect(page).to have_css('li', text: another_recipe.recipe_type)
    expect(page).to have_css('li', text: another_recipe.cuisine)
    expect(page).to have_css('li', text: another_recipe.difficulty)
    expect(page).to have_css('li', text: "#{another_recipe.cook_time} minutos")
  end
end

Passo o comando rspec na pasta do projeto:

E para criar a model recipe na linha do terminal e executar a migration criada em db/migrations:

 

$ rails generate model recipe title:string recipe_type:string cuisine:string difficulty:string cook_time:string
      invoke  active_record
      create    db/migrate/20191016221038_create_recipes.rb
      create    app/models/recipe.rb
      invoke    rspec
      create      spec/models/recipe_spec.rb
$ rspec
Migrations are pending. To resolve this issue, run:

        bin/rails db:migrate RAILS_ENV=test

$ cd bin
$ rails db:migrate RAILS_ENV=test== 20191016221038 CreateRecipes: migrating ====================================
-- create_table(:recipes)
   -> 0.0029s
== 20191016221038 CreateRecipes: migrated (0.0035s) ===========================

O que pode ser alterado nos códigos do projeto que eu não saiba?

 

Aguardo sua resposta.

 

Obrigado,

 

Marcelino

      Passo o seguinte comando rspec especificamente em visitor_visit_homepage_spec.rb linha 11:

      $ 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.

      Onde tem ? na sintaxe, eu não sei o que por e em "textodehref" deve ir:
      recipe.title
      E adicionei os campos ingredientes e cook_method como segue:

      1) Como implementar link_to no arquivo de controller; 2) Como referenciar o objeto recipe de @recipe para detalhar a receita em index.html.erb.
      Pago R$ 30,00 por desafio resolvido por alguém que se manifestar para me ajudar a solucioná-lo(s).
      Aguardo retorno.
      Obrigado,
      Marcelino
