Running this example
https://cloud.google.com/vision/docs/face-tutorial?hl=zh-tw
by rails on 'google-cloud-vision', '~> 0.31.0'
got the error
uninitialized constant Google::Cloud::Vision::ImageAnnotator
here's the code
require "google/cloud/vision"
project_id = 'xxxxxx'
vision = Google::Cloud::Vision.new project: project_id
image_annotator = Google::Cloud::Vision::ImageAnnotator.new
Did you added google-cloud-ruby gem in your Gemfile and other google related authentication details into your ruby project.
It turns out that the error was caused because I haven't use the latest version of gcloud-vision(0.32.x)
the way to do what I wanna do in gcloud-vision(0.31.0) is
image = vision.image "path/to/face.jpg"
face = image.face
instead of using class
Google::Cloud::Vision::ImageAnnotator
I'm using gem 'youtube-dl.rb'.
From irb, I can get full result, about video, but at the rails 4.2 - I can't.
irb
require 'youtube-dl.rb'
a = YoutubeDL.get "https://www.youtube.com/watch?v=5dsGWM5XGdg", {skip_download: true}
Result https://pastebin.com/9SLbs5GF (With a lot of data).
rails c
require 'youtube-dl.rb'
a = YoutubeDL.get "https://www.youtube.com/watch?v=5dsGWM5XGdg", {skip_download: true}
Result from rails console have only this:
=> #<YoutubeDL::Video:0x007fbc29de1498 #url="https://www.youtube.com/watch?v=5dsGWM5XGdg", #options=#<YoutubeDL::Options:0x007fbc29de1448 #store={:skip_download=>true}>, #download_options=#<YoutubeDL::Options:0x007fbc29de1150 #store={:color=>false, :progress=>false, :skip_download=>true}>, #last_download_output="[youtube] 5dsGWM5XGdg: Downloading webpage\n[youtube] 5dsGWM5XGdg: Downloading video info webpage\n[youtube] 5dsGWM5XGdg: Extracting video information\n[youtube] 5dsGWM5XGdg: Downloading MPD manifest\n">
How I Can get the same result for RoR?
Try to check youtube-dl.rb version inside your rails app and inside your machine enviro
I've been using the message_bus gem for a few months as a more simplified alternative to a websocket solution. The default MessageBus.callbackIntervalis too wide, so I want to narrow it. I've done this successfully in my development env. However, when deploying to production it seems that the second line below is ignored:
MessageBus.start();
MessageBus.callbackInterval = 1800; # this should change the interval frequency, but it doesn't
MessageBus.subscribe("/some_id", function(status) {
// work
});
Any idea how I could debug this?
I haven't personally encountered this problem before, but like with many JavaScript libraries/files in Rails it is probably something in the assets pipeline.
Are you certain that you included JavaScript required for message bus to work in your view with:
<script src="message-bus.js" type="text/javascript"></script>
and in assets
//= require message-bus
If you're using a Ruby version of this gem, you can always try to set this using Ruby instead of JavaScript.
client = MessageBus::Client.new('http://127.0.0.1/8000') #port is optional
#you should be able to do
client.callbackInterval = 1800
#after that you should be able to do
client.subscribe('/message') do |payload|
# Do stuff
end

I wanted to use this angular-number-picker plugin in my rails project.
I downloaded the .min.js file and the .js file and put the in the plugins folder. Then I also included the js in
/global_plugins.js
//= require global/plugins/angular-number-picker/angular-number-picker.min.js
and then I also inject it to the dependency of my app
/app.js
var app = angular.module('fotograft', ['ngResource', 'angular-loading-bar', 'cgBusy', 'ngFileUpload', 'MessageCenterModule', 'rails', 'Devise', 'google.places', 'ui.sortable','checklist-model',
'textAngular', 'angularMoment', '720kb.socialshare', 'ngSanitize', '720kb.tooltips', 'angular-md5', 'angularUtils.directives.dirPagination', 'infinite-scroll', 'datatables', 'datatables.bootstrap',
'ngResource', 'frapontillo.bootstrap-switch', 'angular-bootstrap-select','angular-number-picker', 'angular-bootstrap-select.extra', 'ngTextTruncate', 'chart.js', 'timer', 'siyfion.sfTypeahead'])
The problem is when I tried to load any page, the page will not respond. So I tried to view the console and debug, the error was that
Error: [$injector:modulerr] http://errors.angularjs.org/1.3.16/$injector/modulerr?
I truncated the rest of the error messages, because they are kind of long and look gibberish.
So, I would like to ask what am I missing here? I saw from the author's webpage that I need to include the src to the plugin in the html page, but I have no idea which page I should include it in.
Appreciate it if any rails and angularJS developer can help me out here. Thank you very much.
If you double check the link in the source code you provided, it looks like the module name that you have to register is supposed to be angularNumberPicker instead of angular-number-picker.
So you want your app.js module registry to look like this:
var app = angular.module('fotograft', ['ngResource', 'angular-loading-bar', 'cgBusy', 'ngFileUpload', 'MessageCenterModule', 'rails', 'Devise', 'google.places', 'ui.sortable','checklist-model',
'textAngular', 'angularMoment', '720kb.socialshare', 'ngSanitize', '720kb.tooltips', 'angular-md5', 'angularUtils.directives.dirPagination', 'infinite-scroll', 'datatables', 'datatables.bootstrap',
'ngResource', 'frapontillo.bootstrap-switch', 'angular-bootstrap-select','angularNumberPicker', 'angular-bootstrap-select.extra', 'ngTextTruncate', 'chart.js', 'timer', 'siyfion.sfTypeahead']);

You can do it with Nokogiri gem and xml/ json file.
For exmaple:
require 'watir-webdriver'
require 'nokogiri'
browser = Watir::Browser.new :firefox
doc = Nokogiri::XML(File.open('your_file.xml'))
url = doc.at('//url').text
browser.goto(url)
And you must have xml like this:
<url>http://google.com</url>
