Rails Facebook Omniauth get user address

Question

I'm tryig to get the user address from facebook with Omniauth but did not work.

i added their address on update callback after login.

If i removed their address from omniauth the app did not update their address.

Someone have any idea how to get their address and why the app did not edit and update their address after the login?

thank's

def omniauth_callback
    auth_hash = request.env['omniauth.auth']



    user = User.find_by_uid(auth_hash[:uid])
    if user.nil? && auth_hash[:info][:email]
      user = User.find_by_email(auth_hash[:info][:email])
    end

    if user.nil?
      email_domain = ''
      email_domain = '@facebook.com' if auth_hash[:provider] == 'facebook'
      user = User.new(email: auth_hash[:info][:email] || auth_hash[:info][:nickname] + email_domain, name: auth_hash[:info][:first_name] || '', surname: auth_hash[:info][:last_name] || '', gender: 'I')

      user.password_digest = ''
      user.save!(validate: false)
    end

    user.update_attribute(:login_at, Time.zone.now)
    user.update_attribute(:address)
    user.update_attribute(:neighborhood)
     user.update_attribute(:postal_code)
    user.update_attribute(:ip_address, request.remote_ip)
    user.update_attribute(:provider, auth_hash[:provider])
    user.update_attribute(:uid, auth_hash[:uid])
    user.update_attribute(:oauth_token, auth_hash[:credentials][:token])
    user.update_attribute(:oauth_expires_at, Time.at(auth_hash[:credentials][:expires_at]))

    cookies[:auth_token] = { value: user.oauth_token, expires: user.oauth_expires_at}
    redirect_to root_url
  end

One reason your code will not work is because this

user.update_attribute(:address)

Doesn't do anything - except raise an error. You have to pass a value into update_attribute as well as specify the field.

Also as @mysmallidea points out, you'd be better advised to use update as that will allow you to update multiple fields in one database action.

If present, the address data will be within the auth_hash. So I suggest that you first work out the structure of that hash. In your development environment, add the following:

Rails.logger.info auth_hash.inspect

That will output the current auth_hash to logs/development.log. Use that to determine where in the hash the address data is. You'll then be able to do something like:

user.update address: auth_hash[:info][:address]

However, you may find that the address is not included in the data returned by the facebook oauth system. In which case you will need to return to their documentation to see if this is possible.
