I got some problem with OmniAuth FaceBook login into my webapp.
Tell me please, what should i edit to fix this error? Check the code.
Error in the browser:
undefined method `to_a' for "Name Surname":String
User.rb:
def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
x = auth.info.name.to_a
user.name = x[0]
user.surname = x[1]
user.login = auth.info.uid
user.email = auth.info.email
user.password = Devise.friendly_token[0,20]
end
end
Omniauth_callback_controller.rb :
def facebook
if request.env["omniauth.auth"].info.email.blank?
redirect_to "/users/auth/facebook?auth_type=rerequest&scope=email"
end
#user = User.from_omniauth(request.env["omniauth.auth"])
if #user.persisted?
sign_in_and_redirect #user, :event => :authentication #this will throw if #user is not activated
set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
else
session["devise.facebook_data"] = request.env["omniauth.auth"]
if(#user.surname.nil?)
redirect_to new_profile_path
else
redirect_to my_profile_path
end
end
end
devise.rb :
config.omniauth :facebook, '*********', '*********', {:client_options => {:ssl => {:verify => false}}}

Answer 1

name is a string and you are trying to convert it to array
x = auth.info.name.to_a
use split instead
x = auth.info.name.split
#=> ['Name', 'Surname']

Answer 2

You can make use of OmniAuth first_name and last_name:
Update your devise.rb:
config.omniauth :facebook, '*********', '*********', info_fields: 'email, first_name, last_name', {:client_options => {:ssl => {:verify => false}}}
and your user.rb:
def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
user.name = auth.info.first_name
user.surname = auth.info.last_name
user.login = auth.info.uid
user.email = auth.info.email
user.password = Devise.friendly_token[0,20]
end
end

Answer 3

your user.rb should be like this
def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
x = auth.info.name.split
if x.count > 1
user.name = x[0]
user.surname = x[1]
else
user.name = x[0]
end
user.login = auth.info.uid
user.email = auth.info.email
user.password = Devise.friendly_token[0,20]
end
end
But I would suggest to store in a single field, because name can be of more than two words so it would become difficult to identify name and surname.
