Taks

1. Create a new project rails new
2. Scaffold a resource Project with a name and a description as a string
3. Validates the presence of name
4. Generate a controller StaticPages with an action home
5. Change the content of the new action to Welcome all
6. Prevent the destroy action for Project model (through the routes)
7. Set StaticPages#home as the root of the web app
8. Add (manually) a new action to the StaticPages called privacy and accesible via /privacy
9. Add (manually) a new action to the StaticPages called terms and accesible via /legal
10. Add a route to access StaticPages#terms (Create on last step) via /legal-terms
11. Add (manually) a new action to the StaticPages called location and accesible via /location
12. Change the action StaticPages#location to render a view map when we try to access /location?view=map
13. Generate a migration adding the field rating as a float to the model Project
14. Add a validation to Project model to accept only rating values between 1 and 5 included.
15. Generate a model Todo with a label as a string and a project as a references
16. Look into the new model file to see what was generated
17. Look into the schema file and look what was generated
18. Validates the presence of label
19. Test within the rails console
20. Pretend to scaffold the controller
21. Find the right arguments to skip the existing model files
22. Add a has_many relation in Project to show all its related Todo
23. Restrict the access to Todo#index in the routing file
24. Display the todos of a Project in the Project#index endpoint
25. Generate a migration to add priority attribute to Todo as a integer
26. Declare this field as an enum in Todo model with the possible values of :high, :medium, :low
27. Add the class method total to Project in order to get Project.total returning the amount of projects in the data base
28. Add the class method total to Todo in order to get Todo.total returning the amount of todos in the data base
29. The sentence We currently have n todos within n projects to the home page. Both n should refer to the newly created class methods and todos and projects should plurialize according to the amount.
30. Do training (1) listed below if you need a refresh of the points we went trough.
31. Scaffold a resource Task with fields done as a boolean, label as a string, todo as a reference

35. Test done is false at creation
36. Test Task gets deleted when we delete parent Todo
37. Test project exists (has_one through)
38. Test Task gets deleted when we delete parent Project
39. Generate a mailer ProjectMailer with notify_admin sending an email saying New project NAME was created. Accese HERE where NAME is the name of the project and HERE is a url to the project.
40. Call the mailer from project#create when the creation is a success
41. Add a method open_tasks to Todo returning the current open tasks in it
42. Add a method open_tasks to Todo returning a booblean regarding if it still has open tasks
43. Change the destroy method of todo to raise an StandardError when we try to delete a Todo with open tasks

8. Scaffold Label ressource which has a label, and a color
9. Validate the label is present
10. Validate the color is in the format #FFF or #FFFFFF. F being an hecadecimal value 0-9A-Fa-F
11. a Label can be part of many projects a Project can have many labels (use has_and_belongs_to_many relation)
12. Add a column Labels in the index view of Projects showing the amount of labels related to the Project
13. List all labels related to the Project in the show view of Projects
14. The background of a label cell should be the color defined in the label
