I have 2 files in a directory:
user.rb
class User
def initialize
#token = SECRETS_DATA.fetch('token')
#client = Slack::Client.new token: #token
end
def get_user(userid)
userinfo = #client.users_info(user: userid)['user']['profile']['email']
userinfo.split('#').first
end
end
In a sep file bot.rb I have:
require_relative 'user'
User.new.get_user(id)
However this is giving me:
uninitialized constant Slack::Client (NameError)
Ive tried using require user which gives me - require': cannot load such file -- user (LoadError)
Tried require ./user which gives me the original error message.
You need to use Slack::Web::Client here. So the final code in user.rb looks like as follows..
require 'slack-ruby-client'
class User
def initialize
#token = SECRETS_DATA.fetch('token')
#client = Slack::Web::Client.new token: #token
end
def get_user(userid)
userinfo = #client.users_info(user: userid)['user']['profile']['email']
userinfo.split('#').first
end
end
Ohhh, Please don't forget to run gem install slack-ruby-client
If want we can use RealTimeClient in the same way.

try adding
require 'slack-ruby-client'

When I run rails c, I can call the following class and the method works:
test = SlackService::BoardGameNotifier
test.create_alert("test")
>>method works
I'm trying to set this up in rspec like this:
require 'spec_helper'
require 'slack-notifier'
RSpec.describe SlackService::BoardGameNotifier do
describe '#notify' do
#notifier = SlackService::BoardGameNotifier
it 'pings Slack' do
error = nil
message = "test"
expect(notifier).to receive(:ping).with(message)
notifier.send_message()
end
end
end
But I keep getting the error:
NameError:
uninitialized constant SlackService
Does this have to do with how I set up the module?
My current setup:
slack_service/board_game_notifier.rb
module SlackService
class BoardGameNotifier < BaseNotifier
WEBHOOK_URL = Rails.configuration.x.slack.url
DEFAULT_OPTIONS = {
channel: "board-games-channel",
text: "board games alert",
username: "bot",
}
def create_alert(message)
message #testing
end
end
end
slack_service/base_notifier.rb
module SlackService
class BaseNotifier
include Singleton
def initialize
webhook_url = self.class::WEBHOOK_URL
options = self.class::DEFAULT_OPTIONS
#notifier = Slack::Notifier.new(webhook_url, options)
end
def self.send_message
message = instance.create_alert("test")
instance.notify(message)
end
def notify(message)
#notifier.post blocks: message
end
end
end
Add this to your spec_helper.rb
# spec_helper.rb
ENV["RAILS_ENV"] ||= "test"
require File.expand_path("../config/environment", __dir__)
When running RSpec, Rails doesn't automatically boot up, and therefore doesn't automatically load all the libraries.
Also, I'd suggest creating a .rspec in your app's root folder with the following lines so that spec_helper is automatically loaded for all your RSpec tests:
# .rspec
--format documentation
--color
--require spec_helper
I would use the described_class from Rspec
require 'spec_helper'
require 'slack-notifier'
RSpec.describe ::SlackService::BoardGameNotifier do
describe '#notify' do
it 'pings Slack' do
error = nil
message = "test"
expect(described_class).to receive(:ping).with(message)
notifier.send_message()
end
end
end
I have some experience of Selenium in Python and Cucumber/Watir/RSpec in Ruby, and can write scripts that execute successfully, but they aren't using classes, so I am trying to learn more about classes and splitting the scripts up in to pageobejcts.
I found this example to learn from: http://watir.com/guides/page-objects/ so copied the script and made some minor edits as you'll see below.
I'm using SublimeText 3.x with Ruby 2.4.x on Win10, so you know what tools I'm using.
I put the whole script in to a single .rb file (the only differences are that I replaced the URL and the elements to enter the username and password) and tried to execute it and get the following error:
C:/selenium/ruby/lotw/lotwlogin.rb:3:in `<main>': uninitialized constant Site (NameError).
I added the top line (required 'watir') line and it made no difference to the error encountered.
So I have in lotwlogin.rb essentilly the structure and syntax of the original script with custom elements. However, the core structure is reporting an error and I don't know what to do about it.
Here is my script:
require 'watir'
site = Site.new(Watir::Browser.new :chrome) # was :firefox but that no longer works since FF63
login_page = site.login_page.open
user_page = login_page.login_as "testuser", "testpassword" # dummy user and password for now
user_page.should be_logged_in
class BrowserContainer
def initialize(browser)
#browser = browser
end
end
class Site < BrowserContainer
def login_page
#login_page = LoginPage.new(#browser)
end
def user_page
#user_page = UserPage.new(#browser)
end
def close
#browser.close
end
end
class LoginPage < BrowserContainer
URL = "https://lotw.arrl.org/lotw/login"
def open
#browser.goto URL
##browser.window.maximize
self # no idea what this is for
end
def login_as(user, pass)
user_field.set user
password_field.set pass
login_button.click
next_page = UserPage.new(#browser)
Watir::Wait.until { next_page.loaded? }
next_page
end
private
def user_field
#browser.text_field(:name => "login")
end
def password_field
#browser.text_field(:name => "password")
end
def login_button
#browser.button(:value => "Log On")
end
end # LoginPage
class UserPage < BrowserContainer
def logged_in?
logged_in_element.exists?
end
def loaded?
#browser.h3 == "Welcome to Your Logbook of the World User Account Home Page"
end
private
def logged_in_element
#browser.div(:text => "Log off")
end
end # UserPage
Any assistance how to not get the Site error would be appreciated.
Thanks
Mike
You define class Site only a few lines below. But at that point, it's not yet known.
Move this logic to after all class definitions:
site = Site.new(Watir::Browser.new :chrome) # was :firefox but that no longer works since FF63
login_page = site.login_page.open
user_page = login_page.login_as "testuser", "testpassword" # dummy user and password for now
user_page.should be_logged_in
I have a module and class in a file lib/crawler/page-crawler.rb that looks like this:
require 'oga'
require 'net/http'
require 'pry'
module YPCrawler
class PageCrawler
attr_accessor :url
def initialize(url)
#url = url
end
def get_page_listings
body = Net::HTTP.get(URI.parse(#url))
document = Oga.parse_html(body)
document.css('div.result')
end
newpage = PageCrawler.new "http://www.someurl"
#listings = newpage.get_page_listings
#listings.each do |listing|
bizname = YPCrawler::ListingCrawler.new listing['id']
end
end
end
Then I have another module & class in another file lib/crawler/listing-crawler.rb that looks like this:
require 'oga'
require 'pry'
module YPCrawler
class ListingCrawler
def initialize(id)
#id = id
end
def extract_busines_name
binding.pry
end
end
end
However, when I try to run this script ruby lib/yp-crawler.rb which executes the page-crawler.rb file above and works without the YPCrawler call, I get this error:
/lib/crawler/page-crawler.rb:23:in `block in <class:PageCrawler>': uninitialized constant YPCrawler::ListingCrawler (NameError)
The issue is on this line:
bizname = YPCrawler::ListingCrawler.new listing['id']
So how do I call that other from within my iterator in my page-crawler.rb?
Edit 1
When I just do `ListingCrawler.new listing['id'], I get the following error:
uninitialized constant YPCrawler::PageCrawler::ListingCrawler (NameError)
Edit 2
Here is the directory structure of my project:
Edit 3
My yp-crawler.rb looks like this:
require_relative "yp-crawler/version"
require_relative "crawler/page-crawler"
require_relative "crawler/listing-crawler"
module YPCrawler
end
In your yp-crawler.rb file, based on the structure that you posted, you should have something like:
require 'yp-crawler/version'
require 'crawler/listing-crawler'
require 'crawler/page-crawler'
Try this, in your yp-crawler.rb add the line:
Dir["#{File.dirname(__FILE__)}/crawler/**/*.rb"].each { |file| load(file) }
That should automatically include all files in your /crawler directory at runtime. Might want to do the same for the other directories.
Let me know if that helps :)
https://github.com/oscardelben/firebase-ruby
How do I use firebase across methods and not locally as shown in the examples? Ex: #firebase, See the paste at --
http://bpaste.net/show/501b6a67c8d4
or --
require 'sinatra'
require 'firebase'
require 'bundler'
Bundler.require
# Configure database
configure do
#base_uri = 'https://veriyo.firebaseio.com/'
#firebase = Firebase::Client.new(#base_uri)
end
# Display homepage
get '/' do
erb :index
end
post '/search' do
#username = params["username"]
redirect to("/user/#{#username}")
end
get '/user/:username' do
response = #firebase.push("todos", { :name => #username })
'hello'
end
The #firebase variable's attributes aren't accessible there -- #<NoMethodError: undefined methodpush' for nil:NilClass>`
Set them as constants:
FB_Base_uri = 'https://veriyo.firebaseio.com/'
FB_Firebase = Firebase::Client.new(FB_Base_uri)
In Sinatra, I'm unable to create global variables which are assigned values only once in the application lifetime. Am I missing something? My simplified code looks like this:
require 'rubygems' if RUBY_VERSION < "1.9"
require 'sinatra/base'
class WebApp < Sinatra::Base
#a = 1
before do
#b = 2
end
get '/' do
puts #a, #b
"#{#a}, #{#b}"
end
end
WebApp.run!
This results in
nil
2
in the terminal and ,2 in the browser.
If I try to put #a = 1 in the initialize method, I'm getting an error in the WebApp.run! line.
I feel I'm missing something because if I can't have global variables, then how can I load large data during application instantiation?
before do seems to get called every time there is a request from the client side.
class WebApp < Sinatra::Base
configure do
set :my_config_property, 'hello world'
end
get '/' do
"#{settings.my_config_property}"
end
end
Beware that if you use Shotgun, or some other Rack runner tool that reloads the code on each request the value will be recreated each time and it will look as if it's not assigned only once. Run in production mode to disable reloading and you will see that it's only assigned on the first request (you can do this with for example rackup --env production config.ru).
I ran into a similar issue, I was trying to initialize an instance variable #a using the initialize method but kept receiving an exception every time:
class MyApp < Sinatra::Application
def initialize
#a = 1
end
get '/' do
puts #a
'inside get'
end
end
I finally decided to look into the Sinatra code for initialize:
# File 'lib/sinatra/base.rb', line 877
def initialize(app = nil)
super()
#app = app
#template_cache = Tilt::Cache.new
yield self if block_given?
end
Looks like it does some necessary bootstrapping and I needed to call super().
def initialize
super()
#a = 1
end
This seemed to fix my issue and everything worked as expected.
Another option:
helpers do
def a
a ||= 1
end
end
Building on Theo's accepted solution, it is also possible to do:
class App < Sinatra::Application
set :blabla, ''
namespace '/b' do
get '/baby' do
# do something where bouh is assigned a value
settings.blabla = 'bouh'
end
end
namespace '/z'
get '/human' do
# settings.blabla is available here with newly assigned value
end
end
end
You could use OpenStruct.
require 'rubygems'
require 'sinatra'
require 'ostruct'
configure do
Struct = OpenStruct.new(
:foo => 'bar'
)
end
get '/' do
"#{Struct.foo}" # => bar
end
You can even use the Struct class in views and other loaded files.
