Create a rating system

[OnyJ]

Why ? To get an opinion of the provided massage from the employees. This system ensures to have a good quality service from the masseur and confidence from companies.

How

• [ ] Create the Rating model. In the console : rails g model Rating rating:integer
• [ ] Edit the generated migration. Add the following lines of code : t.belongs_to :masseur, index: true, and t.belongs_to :employee, index: true
• [ ] Edit the generated model. Add these lines : validates :rating, presence: true, belongs_to :masseur, belongs_to :employee
• [ ] In the MasseurProfile model, add the following code :

  def average_rate
  total=0
  @masseur.ratings.each do |rating|
  total = total + rating
  end
  average_rate_result = total / @masseur.ratings.count
  # Get a rounded result
  average_rate_result %= '%.2f'
  end

Test the system in console :

>> rails console --sandbox
>> Masseur.create(email: "test@example.com", password: "123456", password_confirmation: "123456")

# Then create MasseurProfile : take the ID of the last created masseur
>> Masseur.last
>> MasseurProfile.create(masseur_id: the_id_of_the_last_created, first_name: "toto", last_name: "test", description: "Text written to fill the description attribute text text text", authorized: true)

# Do the same steps to create the Employee 
# 1. Employee.create(...)
# 2. EmployeeProfile.create(...)

# Test the Rating system : 
# Create multiple employees :
>> Rating.create(employee_profile: Employee.last, masseur_profile: Masseur.last, rating: 4)
>> Rating.create(employee_profile: Employee.last, masseur_profile: Masseur.last, rating: 2)
>> Rating.create(employee_profile: Employee.last, masseur_profile: Masseur.last, rating: 3)

# Calculate rating :
>> MasseurProfile.last.average_rate

# You should have this result : `3`.

Must Have A functionnal rating system to allow employees rating masseurs.

Votre système ne marchera pas bien ainsi conçu.

A reprendre.

On a pensé à différents moyens de le faire mais on voulait t'en parler pour définir comment on allait procéder (via la prochaine conférence).
