Rails Validation for Username and Email -

Rails Validation for Username and Email -

i have next validation rules username , email.

validates :username, presence: {:message => "please take username.", on: :update}, uniqueness: {:message => "username exisits. please select different one."}, length: {in: 3..15, :message => "username should 3-5 characters long", :allow_blank => true} validates :email, presence: {:message => "please come in email address."}, uniqueness: {:message => "email address exisits. please login!"} validate :email_regex def email_regex if email.present? , not email.match(/\a[^@\s]+@([^@.\s]+\.)+[^@.\s]+\z/) errors.add :email, "please come in valid email address." end end

for username: not want allow other - little letters, dot, numbers.

do need write different validate message email_regex or there simplied version can utilize appending exisiting rules comma ','

you can utilize like:

validates :username, format: { with: /\a([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i}

add comma separate alternative format existing validation username. 1 more thing missed, dummy regex, need apply per purpose.
