Model validation

Hi,

I don’t understand the validate method inside the model objet, when
using the fields are always empty ?

class Personne < ActiveRecord::Base
set_table_name ‘personnes’

has_many :emails

protected

def validate
    if nom = ""
        errors.add( "nom", "Le nom ne peut pas etre vide" )
    end
    if prenom = ""
        errors.add( "prenom", "Le prenom ne peut pas etre vide" )
    end
end

end

Thank you for your help

def validate
    if nom = ""
        errors.add( "nom", "Le nom ne peut pas etre vide" )
    end
    if prenom = ""
        errors.add( "prenom", "Le prenom ne peut pas etre vide" )
    end
end

You are setting nom equal to blank by using nom = “”. Instead, write
nom == “” to compare nom to blank. Of course you’ll do the same with
prenom.

Hey Alex,

you can use the method “validates_presence_of” to validate the fields
in blank:

class Personne < ActiveRecord::Base
set_table_name ‘personnes’

has_many :emails

validates_presence_of :nom, :message => "Le nom ne peut pas etre

vide"
validates_presence_of :prenom, :message => “Le prenom ne peut pas
etre vide”
end

I hope I help you.

Thank you a lot !

No comment about the = and ==, this is the result of working being
tired…
