Whatever that I try to do is generating the error message below:
/home/diogodalla/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/activesupport-5.1.4/lib/active_support/dependencies.rb:292:in `require': Could not load 'active_record/connection_adapters/sqlite3_adapter'. Make sure that the adapter in config/database.yml is valid. If you use an adapter other than 'mysql2', 'postgresql' or 'sqlite3' add the necessary adapter gem to the Gemfile. (LoadError)
I'm using PG on my gemFile, I don't know why it keep looking for sqlite3.

Where do you install libraries ? Try following procedure before running Rails, please.
Remove local libraries and re-install
$ rm -rf ./vendor/bundle
$ bundle install --path ./vendor/bundle
$ bundle exec rails server
I am still quite fresh to Ruby, and especially testing in Ruby. Hopefully the code is not a trainwreck :) I am having issues using any_instance with the Twitter gem, while it works fine on my own classes.
This is (what I believe) the relevant code
require 'twitter'
require 'minitest/unit'
require 'mocha/mini_test'
omitting for brevity....
args = { id: 573536452149182464, id_str: 73536452149182464, text: 'This is an initial tweet from the user'}
initial_tweet = ::Twitter::Tweet.new(args)
::Twitter::REST::Timelines.any_instance.stubs(:user_timeline).returns(initial_tweet)
The code produces the following error:
Minitest::UnexpectedError: NoMethodError: undefined method `any_instance|' for Twitter::REST::Timelines:Module
Are principles to stubbing gems different, am I approaching it wrong?
EDIT: I have added the entire code for the two classes below.

I have written a small Sinatra script to fetch 2 tweets of a user and display 10 retweeters in the descending order of their no. of followers:
Puzzle/puzzle.rb
require 'twitter'
require 'json'
require 'sinatra'
#require 'haml'
client = Twitter::REST::Client.new do |config|
config.consumer_key = ""
config.consumer_secret = ""
config.access_token = ""
config.access_token_secret = ""
end
set :server, 'webrick'
set :haml, :format => :html5
get '/' do
content_type :json
arr = []
retweeters = client.retweeters_of(429627812459593728)
retweeters.each do |retweeter|
ob = {}
ob[:name] = retweeter.name
ob[:followers_count] = retweeter.followers_count
arr.push(ob)
end
# remove the duplicates and sort on the users with the most followers,
sorted_influencers = arr.sort_by { |hsh| hsh[:followers_count] }
sorted_influencers.reverse!
sorted_influencers[0..9].to_s
end
I am trying to handle rate limits.
How to cache the json output to avoid rate limit exceeding?
Assuming you keep your very simple scenario, you could use a small custom class to store the information and provide thread-safe methods (it is not clear from your question where your problem exactly resides, but this one problem will arise anyway):
require 'json'
require 'sinatra'
require 'date'
require 'thread'
require 'twitter'
set :server, 'webrick'
set :haml, :format => :html5
class MyCache
def initialize()
#mutex = Mutex.new
#last_update = DateTime.new # by default, -4732 BC
#client = Twitter::REST::Client.new do |config|
config.consumer_key = ""
config.consumer_secret = ""
config.access_token = ""
config.access_token_secret = ""
end
end
def get_cache
#mutex.synchronize do
if DateTime.now - #last_update > 10.0 / (3600 * 24)
#last_update = DateTime.now
arr = []
retweeters = #client.retweeters_of(429627812459593728)
retweeters.each do |retweeter|
ob = {}
ob[:name] = retweeter.name
ob[:followers_count] = retweeter.followers_count
arr.push(ob)
end
# remove the duplicates and sort on the users with the most followers,
sorted_influencers = arr.sort_by { |hsh| hsh[:followers_count] }
sorted_influencers.reverse!
#cache = sorted_influencers[0..9].to_s
end
#cache
end
end
end
my_cache = MyCache.new
get '/' do
content_type :json
my_cache.get_cache
end
This version now includes everything needed. I use the #client to store the instance of the twitter client (I suppose it's reusable), also note how the whole code is inside the if statement, and at last we update #cache. If you are unfamiliar with Ruby, the value of a block is determined by its last expression, so when I write #cache alone it is as if I had written return #cache.
I'm trying to configure the debuglevel for active-record logger from a YAML configuration file but get the following error, how could i do this other than using a number in the YAML ?
sample.rb:30 warning: toplevel constant LEVEL referenced by Logger::LEVEL
"DEBUG"
ArgumentError: comparison of Fixnum with String failed
here is the sample.rb
require 'java'
require 'active_record'
require 'activerecord-jdbc-adapter'
require 'yaml'
require 'logger'
def get_jar_path
if __FILE__[/.+\.jar!/] #in case run from JAR
scriptpath = __FILE__[/(.*)\/.+\.jar!/]
$1[6..-1]
else #in case run with jRuby
'..'
end
end
def load_config
path = "#{get_jar_path}/#{File.basename(__FILE__, ".*")}.configuration.yml"
p path
$conf = YAML::load_file(path)
end
load_config
LEVEL = $conf['debug_level'] #string 'DEBUG' from configuration file
$log = Logger.new( "#{get_jar_path}/log_#{Time.now.strftime("%Y%m%d")}.txt", 'monthly' )
ActiveRecord::Base.logger = $log
ActiveRecord::Base.logger.level = Logger::DEBUG #works
ActiveRecord::Base.logger.level = Logger::LEVEL #doesn't work
p ActiveRecord::Base.logger.level
$log.info "start #{__FILE__}"
The available log levels are: :debug, :info, :warn, :error, :fatal,
and :unknown, corresponding to the log level numbers from 0 up to 5
respectively.
http://guides.rubyonrails.org/debugging_rails_applications.html
require 'logger'
puts Logger::DEBUG
--output:--
0
str = "DEBUG"
puts Logger.const_get(str)
--output:--
0
So you should do something like:
level = $conf['debug_level'] #string 'DEBUG' from configuration file
$log = Logger.new( "#{get_jar_path}/log_#{Time.now.strftime("%Y%m%d")}.txt", 'monthly' )
ActiveRecord::Base.logger = $log
ActiveRecord::Base.logger.level = Logger.const_get(level)
I'm not sure why you thought defining a constant, LEVEL, in the current scope would make that constant appear in the Logger scope, so that you could write Logger::LEVEL. You essentially did this:
MYCONST = "hello"
module SomeModule
SOMECONST = "goodbye"
end
You can write:
puts MYCONST #=>hello
..and you can write:
puts SomeModule::SOMECONST #goodbye
..but you cannot write:
puts SomeModule::MYCONST
--output:--
1.rb:10:in `<main>': uninitialized constant SomeModule::MYCONST (NameError)
This is the Sinatra code that I wrote. All gems exist, the ruby files compiles perfectly but when i go to localhost:4567/ the sinatra app doesnt run. It takes me to the 'Sinatra doesnt know this ditty' page. What mistake am i making here? Is it a syntax issue? I've posted the main ruby file's code here others are just haml files thats all.
require 'bundler'
Bundler.setup(:default)

As you have a modular app do you need to require "sinatra/base" rather than "sinatra"? See here
See Serving a Modular App and add the line run! if app_file == $0 at the end of the class. Also see DavB's answer.
