How to add custom errors to the User errors collection?

Question

How can I add errors to the User model manually?

Is it just @user.errors << \"some text goes here\" ?

Answer 1

WARNING

If you just add errors in a separate method (not in a validation), then by default when you call .valid? or .save those errors will be automatically cleared. So you may want to use validation contexts instead.

Answer 2

 @user.errors.add(:email, "Not valid")

If you don't want to use any attributes, then in your model

 @user.errors[:base] << "This person is invalid because ..."

Answer 3

try this:

errors.add(:base, "#{user.full_name} has errors here!")

Answer 4

Use the errors.add method

Example:

@user.errors.add(:name, "wasn't filled in")
