Can't write unknown attribute `recipe_type_id`

1

When downloading the repository on the machine, I gave the following commands:

$ rails generate migration RemoveRecipe_ *typeToRecipe recipe_* type:string

$ rails db:migrate RAILS *ENV=test*

*$ rails generate model recipe_* type name:string

$ rails db:migrate RAILS_ENV=test

I modified the recipe_type.rb and createrecipe_type.rb files as mentioned below and passed the same rails db: migrate mentioned.

These are the main ruby on rails project files:

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_recipe.rb:

class CreateRecipes < ActiveRecord::Migration[5.2]

  create_table :recipe_types do |t|
    t.string :name
    t.timestamps
  end

  def change
    create_table :recipes do |t|
      t.string :title
      t.string :recipe_type
      t.string :cuisine
      t.string :difficulty
      t.integer :cook_time
      t.belongs_to :recipe_type      
      t.timestamps
    end
  end
end

create_recipe_type.rb:

class CreateRecipeTypes < ActiveRecord::Migration[5.2]
  def change
    create_table :recipe_types do |t|
      t.string :name

      t.timestamps
    end

    create_table :recipes do |t|
      t.string :title
      t.string :recipe_type
      t.string :cuisine
      t.string :difficulty
      t.integer :cook_time
      t.belongs_to :recipe_type
      t.datetime :published_at
      t.timestamps
    end
  end
end

recipes_controllers.rb:

class RecipesController < ApplicationController
  def index
    @recipes = Recipe.all
  end

  def show
    @recipe = Recipe.find(params[:id])
  end

  def new
    @recipe = Recipe.new
  end

  def create
    @recipe = Recipe.new(recipe_params)
    if @recipe.save
      redirect_to @recipe
    else
      flash[:alert] = 'Você deve informar todos os dados da receita'
      render :new
    end
  end

  def edit
    @recipe = Recipe.find(params[:id])
  end

  def update
    @recipe = Recipe.find(params[:id])
    if @recipe.update(recipe_params)
      redirect_to @recipe
    else
      flash[:alert] = 'Você deve informar todos os dados da receita'
      render :edit
    end
  end

  private

  def recipe_params
    params.require(:recipe).permit(:title, :recipe_type, :cuisine, :difficulty,
                                   :cook_time, :ingredients, :cook_method)
  end
end

index.html.erb:

<h1>CookBook</h1>
<p>Bem-vindo ao maior livro de receitas online</p>

<%= link_to 'Enviar uma receita', new_recipe_path %>

<% @recipes.each do |recipe| %>
  <h1><%= link_to recipe.title, recipe %></h1>
  <ul>
    <li><%= recipe.recipe_type %></li>
    <li><%= recipe.cuisine %></li>
    <li><%= recipe.difficulty %></li>
    <li><%= recipe.cook_time_min %></li>
  </ul>
<% end %>

I pass the following rspec command specifically on visitor_visit_homepage_spec.rb line 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]}}

  and view recipe (FAILED - 1)

Failed examples:

rspec ./spec/features/visitor_visit_homepage_spec.rb:11 # Visitor visit homepage and view recipe

And after making changes to the recipe.rb and create_recipe.rb files, I ran the following command again:

$ rails db:migrate RAILS_ENV=test

I don’t understand why the error, relationships between the tables are not made?

I am participating in Locaweb’s selection process, and there are 4 challenges left to complete the delivery of the challenges and the deadline is 28/10/2019.

I look forward to a comment, tip or suggestion.

Thanks,
