Ruby on Rails ActiveRecord::Enum
Ruby on Rails Vamos adicionar uma migration para a role
rails g migration AddRoleToUsers
Ruby on Rails Altere a migration add_column :users, :role, :integer,
: default => 0
Ruby on Rails Adicione ao Model User enum role: [:normal_user,
:admin]
Ruby on Rails Rode a migration e teste um a
criação de um novo user
Ruby on Rails Ajuste a visualização dos usuários
Ruby on Rails Faça testes no rails console
Ruby on Rails Pundit
Ruby on Rails Adicione ao Gemfile... gem ‘pundit’
Ruby on Rails Rode o bundle install
Ruby on Rails Inclua o Pundit no ApplicationController class ApplicationController
< ActionController::Base include Pundit protect_from_forgery end
Ruby on Rails Instale o pundit na aplicação rails g
pundit:install
Ruby on Rails Após a instalação o pundit irá criar
a pasta app/policies
Ruby on Rails Crie uma nova política para o model
User rails g pundit:policy user
Ruby on Rails Index Customer Products Usuários Autenticados (normal_user, admin)
Addresses ControlUsers Usuários Autenticados (admin)
Ruby on Rails Teste o controller control_user def index …
authorize @user end
Ruby on Rails Crie o método para testar se o
usuário é admin def index? user.admin? end
Ruby on Rails Ajustando mensagens de erro rescue_from Pundit::NotAuthorizedError, with:
:user_not_authorized private def user_not_authorized flash[:alert] = "Você não tem permissão para fazer esta ação." redirect_to(request.referrer || root_path) end
Ruby on Rails Agora façamos o mesmo para o model
Address rails g pundit:policy address
Ruby on Rails Testando na View <% if policy(@address).index? %>
... <% end %>
Ruby on Rails Crie o método para testar se o
usuário é admin def index? user.admin? end
Ruby on Rails Obrigado!
