Undefined method `OAuth' when making HTTP request to Twitter api - ruby-on-rails

Question

I'm getting the following OAuth error when trying to make a request to the Twitter streaming api:
"#NoMethodError: undefined method `OAuth' for #TwitterMoment:0x007fa081d821f0"
def query
authorisation_header = OAuth oauth_consumer_key=ENV["oauth_consumer_key"], oauth_nonce=ENV["oauth_nonce"], oauth_signature=ENV["oauth_signature"], oauth_signature_method=ENV["oauth_signature_method"], oauth_timestamp=ENV["oauth_timestamp"], oauth_token=ENV["oauth_token"], oauth_version=ENV["oauth_version"]
response = HTTParty.get("https://stream.twitter.com/1.1/statuses/filter.json?locations=-#{#bounds}", headers: {"Authorization" => authorisation_header})
end
OAuth is included in my gemfile.
Any ideas would be very much appreciated! This is my first Stack Overflow question :)

Answer 1

You're using OAuth here as a function/method, but that method doesn't exist. There's no def OAuth(...) anywhere in the oauth gem, so it explodes and gives you that NoMethodError.
Judging from the Header example at the bottom of this question, I think you've confused the header string for Ruby code.
Instead, you either need to make the string yourself (a bit annoying to do safely), or use the OAuth gem's methods (API) to do so.
Here's an example from the OAuth github repo:
consumer = OAuth::Consumer.new(
options[:consumer_key],
options[:consumer_secret],
:site => "http://query.yahooapis.com"
)
access_token = OAuth::AccessToken.new(consumer)
response = access_token.request(
:get,
"/v1/yql?q=#{OAuth::Helper.escape(query)}&format=json"
)
rsp = JSON.parse(response.body)
pp rsp
This example may work for you (I'm not able to test it locally here, sorry):
def query
consumer = OAuth::Consumer.new(
ENV["oauth_consumer_key"],
ENV["oauth_consumer_token"],
site: "https://stream.twitter.com"
)
access_token = OAuth::AccessToken.new(consumer)
response = access_token.request(
:get,
"/1.1/statuses/filter.json?locations=-#{OAuth::Helper.escape(#bounds)}"
)
response = JSON.parse(response.body)
pp response # Just a bit of debug printing for the moment; remove this later.
response
end
An addendum:
Usually I might have directed you to use an existing Twitter client gem, such as https://github.com/sferik/twitter, but in this case it looks like they haven't implemented the Moments API yet.
