google_contacts_api - undefined method `get' for #<String:0x007fce71ad54e8> Did you mean? gem

Question

I'm working to use the google_contacts_api: https://github.com/aliang/google_contacts_api

I have the following code in user.rb:

google_contacts_user = GoogleContactsApi::User.new(self.authentications.first.token)
@x = google_contacts_user.contacts

self.authentications.first.token is the token stored via omniauth-google-oauth2.

Problem is, this is erring:

undefined method `get' for #<String:0x007fce71ad54e8> Did you mean? gem

What am I doing wrong?

Answer 1

First install oauth2

 gem install oauth2

And then create an Oauth2AccessToken instance from the token string

 oauth2_object = OAuth2::AccessToken.new(self.authentications.first.token)

Now it should be possible to use this Oauth2AccessToken with the GoogleContacts gem:

 GoogleContactsApi::User.new(oauth2_object)

I'm basing this on the gem's docs

You need to pass to the GoogleContactsApi::User constructor one of the following two objects:

an OAuth::AccessToken from the oauth-ruby gem an OAuth2::AccessToken from the oauth2 gem
