Question

I have omniauth set up correctly and I am able to parse several other provider responses, including some of the attributes for a YouTube user but I am not able to get the YouTube user’s link to their channel. Here is what the response looks like, I am trying to get the link on the last line:

--- !ruby/hash:OmniAuth::AuthHash
provider: youtube
uid: http://gdata.youtube.com/feeds/api/users/DLjkduRouoiweRktkkl
info: !ruby/hash:OmniAuth::AuthHash::InfoHash

  last_name: User

      .

      .

I can get to things like “nickname” at the top by doing this in my user model:

def add_omniauth(auth)
  user.name = auth["info"]["nickname"]
end

But how on earth do I get to that URL at the very bottom? I tried:

user.link = auth["extra"]["user_hash"]["link"]["href"]

but to no avail. As a rails and ruby newbie, I appreciate the help.

Okay, so as it turns out, link: in the youtube response is an array. You can tell because it isn’t listed as a hash next to it. I learned that after speaking with a friend of mine over here. So in order to get that link at the bottom of the response:

self.url = auth["extra"]["user_hash"]["link"].first["href"]
