#Tasks Project ##Simple tasks application ###Built following tutorial on nettuts

1. rails new tasks -T to build rails project without testing framework (most rail devs prefer Rspec)
2. add gems to Gemfile group :test, :development do gem 'turn' # pretty printing gem 'rspec-rails' gem 'capybara' # assistant, simulates user gem 'guard-rspec' # automatically runs tests gem 'ruby_gntp' # notification on mac end NOTE: add notification :off to Guardfile to get rid of growl errors
3. run bundle install
4. rails g < what generators available?
5. rails g rspec:install
6. guard init rspec < initialize guard with rspec
7. guard < start guard
8. rails g integration_test tasks
9. go to requests/spec/tasks_spec.rb
10. remove default test inside describe "GET /tasks" do
11. add: it "display some tasks" do visit tasks_path end
12. add: config.include Capybara::DSL to line 12 on spec/spec_helper.rb
13. add resource route in config/routes (creates CRUD/REST): resources :tasks
14. on requests/spec/tasks_spec.rb add: page.should have_content 'go to bed'
15. add tasks controller > rails g controller Tasks index
16. add root :to =>"Tasks#index" to routes.rb to make this default
17. initialize model: rails g model Task task:string [use singular, Active Record can use Task.all for example. task:string is column, no need for primary key, rails does this automatically]
18. rake db:migrate
19. rails console to test db
20. Task.create :task => 'Go to the store'; Task.all, Task.find
21. Add @task = Task.create :task => 'go to bed' to tasks_spec.rb to test creating new entry
22. Remove turn altogether (uninstall gem + remove from gemfile)
23. Create instance variable in tasks_controller index action
24. In views/tasks/index.html.erb:

<% for task in @tasks %>
• <%= task.task %>
<% end %>

current_path.should == root_path page.should have_content 'go to work'

save_and_open_page # opens page in browser in this state 27. Add gem 'launchy' # enables save_and_open_page 28. Add form on tasks/index.html.erb <%= form_for Task.new do |f| %> <%= f.label :task %> <%= f.text_field :task %> <%= f.submit %> <% end %> 29. Create new action in tasks controller def create Task.create params[:task] redirect_to :back end 30. Change tasks_spec to current_path.should == tasks_path 31. Update tasks_spec:

require 'spec_helper'

describe "Tasks" do before do @task = Task.create :task => 'go to bed' end

describe "GET /tasks" do it "display some tasks" do

    visit tasks_path
    page.should have_content 'go to bed'

  end

  it "creates a new task" do
    visit tasks_path
    fill_in 'Task', :with => 'go to work'
    click_button 'Create Task'

    current_path.should == tasks_path
    page.should have_content 'go to work'

    # save_and_open_page # opens page in browser in this state

  end

end

describe "PUT /tasks" do it "edits a task" do visit tasks_path click_link 'Edit'

  current_path.should == edit_task_path(@task)

  # page.should have_content 'go to bed'
  find_field('Task').value.should == 'go to bed'

  fill_in 'Task', :with => 'updated task'
  click_button 'Update Task'

  current_path.should == tasks_path

  page.should have_content 'updated task'

end

end end 32. Add Edit link to index.html: | <%= link_to 'Edit', edit_task_path(task) %> 33. Move form code from index.html.erb to partial at form.html.erb 34. Put <%= render 'form' %> in both index and edit views 35. Use instance variable @task to replace Task.new in partial, add it to index action (already added to edit) 36. Add update to controller: def update task = Task.find params[:id] if task.update_attributes params[:task] redirect_to tasks_path else redirect_to :back end 37. Validation: add validates :task, presence: true to models/task.rb 38. Error handling: in application layout <% flash.each do |name, message| %>

<%= content_tag :div, message, :id => "flash_#{name}" %> <% end %> 39. In tasks controller: def update task = Task.find params[:id] if task.update_attributes params[:task] redirect_to tasks_path, :notice => 'Your task was updated.' else redirect_to :back, :notice => 'There was an error updating your task.' end 40. To delete

def destroy if Task.destroy params[:id] redirect_to :back, :notice => 'Task has been deleted' else redirect_to :back, :notice => 'There has been an error' end end
