Rails-Devise：检查用户是否可以登录

Question

I use devise to deal with Session.

I need to check if a user is validate by admin before sign in.

I added a boolean field in my model 'is_validated'.

How can I check this field before sign_in a user ?

Answer 1

You need to overwrite the active_for_authentication? function of devise. Basically you place your extra condition in that method and only if that method is true one can log in.

You can find more details here: https://github.com/plataformatec/devise/wiki/How-To:-Customize-user-account-status-validation-when-logging-in

Answer 2

Overwrite the active_for_authentication? method in your model

Like this .......

class Your_model

  def active_for_authentication?
    super && is_validated?
  end

end

This returns true if user is validated.
