Model Validation


    

  • Validations are used to ensure that only valid data is saved into your database.
    • 



Types of Validation


    

  • Database constriants: database-dependent, testing and maintenance difficult
    • 

  • Client-side validation: unreliable, immediate feedback on the client-side
    • 

  • Controller-level validation: difficult to test and maintain, controller should  be slim
    • 



Method Trigger Model Validation


    

  • create and create!
    • 

  • save and save!
    •
