| Capistrano 3.0 Rails 5.0.0 database custom task Posted: 01 Jan 2017 07:05 AM PST I have deployed a Rails app on an Ubuntu server with Capistrano. However I am trying to run a custom task I had created and is in 'lib/tasks'. I tried to make it work by executing cap production db:views As if it was a custom task, but obviously it did not worked cap aborted! Don't know how to build task 'db:views' The file is sql_views.rake, this task is for create views in the database namespace :db do desc "Update and create SQL views" task :views => :environment do Dir["#{Rails.root}/db/sql_views/*.sql"].each do |file_name| STDERR.puts "Applying the SQL view at #{file_name}" source_file = File.new(file_name, 'r') if source_file and (sql_content = source_file.read) ActiveRecord::Base.transaction do # Each statement ends with a semicolon followed by a newline. sql_lines = sql_content.split(/;[ \t]*$/) if sql_lines.respond_to?(:each) sql_lines.each do |line| ActiveRecord::Base.connection.execute "#{line};" end end end # transaction end end # Dir.each end # task end

| Ruby extra all attribute from img tag Posted: 01 Jan 2017 06:09 AM PST I was trying to use nokogiri to turn this line <img class="img-responsive" src="img/logologo.png" alt="">
to <%= image_tag('img/logologo.png', :class => 'img-responsive', :alt => '') %>
Here is my code # a = <img class="img-responsive" src="img/logologo.png" alt="" width="256" height="256"> page = Nokogiri::HTML(a) img = page.css('img')[0] src = "" alt = "" class_atr = "" src = img['src'] if img['src'].present? alt = img['alt'] if img['alt'].present? class_atr = img['class'] if img['class'].present? result = "<%= image_tag(\'" + src + '\', :class => \'' + class_atr + '\', :alt => \'' + alt + '\')%>'
This is kind of like hard code, is there a way I can extra all attribute name and its volume? Maybe the image tag may contain height or width, how do I extra all attribute automatically and make it into erb style? |

It does not allow me to click it and navigate to the correct page. If I remove the <a> tags, it works but I need the <a> because its have the correct class associated with it to style the button. The above code is styled correctly but when trying to click it it does not link to the right page. |
| Asynchronously log every request for current_user Posted: 01 Jan 2017 04:16 AM PST I'm tracking last web session when a user is logged in. I plan to put this in a background job, and trigger it in ApplicationController since it will be for almost every request. I currently set current_user in a before_action: def current_user if session[:user_id] @current_user ||= User.find(session[:user_id]) end end
The trigger in an after_action: def log_session WebSessionJob.perform_later(current_user) if current_user.present? end

| Making column in Database cannot be done Posted: 01 Jan 2017 03:59 AM PST Making column in Database cannot be done in my app. I did 'rails g model userdata' and 'rake db:migrate' ,so I could create create_table(:userdata) and could get below file. class CreateUserdata < ActiveRecord::Migration def change create_table :userdata do |t| t.string :name t.text :image t.timestamps null: false end end end
Furthermore,I did 'rake db:migrate',in Sequel Pro userdata table could be made but name&image column could not be made.What should I do to make name&image column? In schema.rb,I wrote ActiveRecord::Schema.define(version: 20170101073143) do create_table "userdata", force: :cascade do |t| t.datetime "created_at", null: false t.datetime "updated_at", null: false end end

| Deployment issue with Elasticsearch and Sidekiq using Redis on Heroku Rails 5 Posted: 01 Jan 2017 02:52 AM PST Problem: my search queries using Elasticsearch with Sidekiq to process background jobs are not working. Search feature is working in localhost but not in production on Heroku. WHY? Damn it. Thoughts: Should I upgrade to Professional Dyno? On Heroku Dashboard, I have exceeded Memory Usage for Hobby dyno or are there any other ways to lower it? (Max: 734 MB, Average: 397 MB) Was my sidekiq.rb configured correctly? Is it normal to have such high memory usage for Sidekiq background processing? (hmm, everything looks normal and decent except for memory usage) Attempts: I googled a lot, and I have seen how other people implemented initializer/sidekiq.rb and followed. No success. Followed doc from Sidekiq Wiki(https ://github.com/mperham/sidekiq/wiki/Using-Redis) (sorry... I can only put two links rn since I'm new) and Julianee's Guide (http: //julianee.com/rails-sidekiq-and-heroku/) but did not work. There were more bugs along the way but I fixed them all. However, I am NOT sure about this one... I've been stuck. Hopefully, if you have better understanding in backend, please teach me THE WAY...:) The error I got before(I followed Julianee's Guide and got it. Later, I changed it back to Sidekiq Wiki. )... 2017-01-01T09:23:11.150280+00:00 heroku[web.1]: Process running mem=530M(103.5%) 2017-01-01T09:23:11.150280+00:00 heroku[web.1]: Error R14 (Memory quota exceeded) 2017-01-01T09:23:16.091264+00:00 app[worker.1]: D, [2017-01- 01T09:23:16.091146 #4] DEBUG -- : Delayed::Backend::ActiveRecord::Job Load (2.8ms) UPDATE "delayed_jobs" SET locked_at = '2017-01-01 09:23:16.087535', locked_by = 'host:aa0b7e74-6cb0-4548-b002-dec01f0bb60a pid:4' WHERE id IN (SELECT "delayed_jobs"."id" FROM "delayed_jobs" WHERE ((run_at <= '2017-01-01 09:23:16.086816' AND (locked_at IS NULL OR locked_at < '2017-01-01 05:23:16.086898') OR locked_by = 'host:aa0b7e74-6cb0-4548-b002- dec01f0bb60a pid:4') AND failed_at IS NULL) ORDER BY priority ASC, run_at ASC LIMIT 1 FOR UPDATE) RETURNING *

I will add more pictures of some parts of my code if you need more information... As I said, I can only add two links/photos in this post for now... Thank you all, hope you learn something or decide to help me out, and Happy New Year :) I won't stop debugging. |
| Find and update a collection in JSONB Posted: 01 Jan 2017 02:51 AM PST I have a Rails 5.0 app with a JSONB column called data, which contains an array of hashes: [ {'event': 'web_session', 'user_id': 1, 'count': 13}, {'event': 'web_session', 'user_id': 2, 'count': 10}, {'event': 'web_session', 'user_id': 3, 'count': 42} ]
How would I update one of the hashes, e.g. matching 'user_id': 2, with a different count value? Is this the most efficient way (I'd potentially have ~1 million hashes): h = data.find {|h| h['user_id'] == 2} h['count'] = 43 save

| Rails Active Admin form display based on checked booleans? Posted: 01 Jan 2017 12:29 AM PST I've got a simple Active Admin form that is displaying a lot of form fields, but only some of the form fields will be needed if a boolean is checked on that record.

| AngularJS ng-change does not work when get request with Ruby on Rails 5 Posted: 01 Jan 2017 06:31 AM PST I'm using ... - Ruby on Rails 5
- AngularJS 1.3.20
- Chrome or FireFox Browser
It seems ng-change event does not work, when I request get method like link from other page. But when I user POST request to next page, it works. When I change select box value, onchange event is not happen. I expect ng-change should reach changeHandler function in sample.js and console.log("ChangeHandler!!!") show up. In addition, I use Ruby on Rails application template. So ng-app and ng-controller is same as index1.html and index2.html. ** Additional Info I tried Chrome ng-inspector for AngularJS Tool. But There is no angular panel shown up. But once reload same page, it shows up. What happend? index1.html.erb <html lang="ja" ng-app="MyApp"> <body ng-controller="MyController"> <!-- For GET Method Request --> <div> <%= link_to 'Index2', sample_index2_path %> </div> <!-- For POST Method Request --> <div> <%= form_tag sample_index2_path do %> <%= button_tag "Click" %> <% end %> </div> </body> </html>
index2.html.erb <html lang="ja" ng-app="MyApp"> <body ng-controller="MyController"> <div> <form> <select id="eventTest" ng-model="eventTest" ng-change="changeHandler()"> <option value="1">AAA</option> <option value="2">BBB</option> <option value="3">CCC</option> </select> </form> </div> </body> </html>
sample.js angular.module('MyApp',[]) .controller("MyController", ['$scope', function($scope) { $scope.eventTest; $scope.changeHandler = function () { console.log("ChangeHandler!!!"); }; }]);
This works only POST, or Get and reload Browser. There are any difference between output HTML source code GET and POST. I'm stack over 3 days. Please let me know and advice for me. |

| Rake task to fetch current price and update object attribute Posted: 31 Dec 2016 11:15 PM PST I have a Portfolio model and am currently running rake tasks to fetch updated price data from Yahoo Finance API, updating the amounts for the Portfolios and create a new Valuation object that takes a snapshot of each portfolio and their values. A Portfolio has_many Positions that store tickers and their prices. Positions has a has_many association to Movements that act as buy/sell actions and add/subtract from a Portfolio's amount. The Portfolio methods I'm using to fetch updated price data and update my portfolio amount are: def new_price_data price_array = [] if !positions.empty? positions.each do |pos| price = YAHOO_CLIENT.quotes([pos.ticker], [:last_trade_price]).first price = price['last_trade_price'].to_f price = price * pos.quantity price_array << price end else price_array << 0 end price_array end def calculate_amount price = self.new_price_data.inject(&:+) price end def update_portfolio_amount update_attribute(:amount, self.calculate_amount.round(2)) end
In my rake file I have an update_price task in the valuation namespace: desc "Retrieve real-time price data" task update_price: :environment do Portfolio.all.each do |portfolio| portfolio.update_portfolio_amount end end
When I run the body of the task (Portfolio.all.each...) it runs on all my Portfolio objects. For some reason it doesn't run when I schedule it in my cron tab with whenever. every 1.day, :at => '1:55 am' do rake "valuation:update_price", :environment => 'development' end
My other rake task that is simply creating a new Valuation object on all Portfolios and taking a snapshot of their values for a given day works fine. I've tested this using rake valuation:update_price. There is a message saying Running via Spring preloader in process 23522
but when I check my Portfolios my rails console, they haven't updated. I'm not sure where my error is? |
| On rails configuration, use systematically the latest installed version of Ruby Posted: 01 Jan 2017 05:08 AM PST Since when I execute "bundle install" I get the message error: Gem::InstallError: devise requires Ruby version >= 2.1.0. An error occurred while installing devise (4.2.0), and Bundler cannot continue.
Which is the simplest way, to put as a default version, the last one (ruby 2.3.3 that I already installed), as it seems that I still use the old version, as indicated on Rails configuration  Through my different searches on google, I couldn't manage to find a simple solution; As I will not use anymore the old versions, a solution like RVM seems too complicated, my wish is just to use the latest installed version of Ruby, as the default version on Rails PS: I am on windows Many thanks |
| Missing Cookbooks with chef kitchen Posted: 01 Jan 2017 12:47 AM PST Trying to setup a rails app using chef but getting Missing Cookbooks error.

Questions - I am able to fix the error but I don't understand "why" this error occurred.I think this is related to
chef_repo_path but don't really understand it. so if can explain or point to relevant docs? - Should I be vendoring the cookbooks into
./cookbooks instead of ./cookbooks/chef_rails/berks-cookbooks/. if yes, then how do I make berks vendor do that? - After development, For uploading to github. should include the vendored cookbooks in the repo as well? Planning to use these cookbooks with Chef Server to setup server for rails.

| CKEditor: how to use drop down menu with options Posted: 01 Jan 2017 01:24 AM PST I implemented CKEditor in my Ruby on Rails app and now I could format text and use links: CKEditor: how to get clcikable links Can I use CKEditor to get drop down menu with options? For ex. User provides 4 pictures with numbers: # 1,2,3,4 for each of them and he or she would like to know what is the best pictures? Pictures are downloading separately and this downloading is not connected with CKEditor. Users using CKEditor, should use drop down menu to check which picture(#1 or 2 or 3 or 4) they like the most. If, for ex. more users choose #3, then #3 picture is considered the best one. I think that need to use html to get drop down menu and programming tools (loop, conditions) to estimate what picture is the best. Is it possible to get drop down menu with the checked choice to inform users what pictures is the best(got more voters), and if so, how to accomplish this task? thanks. |

| Rails Ajax 'Uphold/Like' Button doesn't work Posted: 01 Jan 2017 03:36 AM PST I can't figure out why my 'Uphold(Like)' button doesn't work. My app is a kind of Q&A web site, named 'KnowledgeSprout'. And I appended 'like' feature, named 'uphold', like StackOverFlow's useful button. The code are below. It look like counting up is working, but the image can't turn to red dynamically. UpholdController.rb class UpholdsController < ApplicationController def create @uphold = Uphold.create(user_id: current_user.id, knowledge_sprout_id: param s[:knowledge_sprout_id], answer_id: params[:answer_id], review_id: params[:revie w_id], product_review_id: params[:product_review_id]) @knowledge_sprouts = KnowledgeSprout.find(params[:knowledge_sprout_id]) end end
And KnowledgeSproutController.rb class KnowledgeSproutsController < ApplicationController def show @knowledge_sprout = KnowledgeSprout.find_by(id: params[:id]) @q = Restaurant.ransack(params[:q]) if params[:q].present? @restaurants = @q.result(distinct: true).page(params[:page]) end @answers = Answer.where(ks_id: params[:id]) @answer = Answer.new ahoy.track "ks_show", id: params[:id] end end
Here's knowledege_sprout.html.slim .upholds = render partial: "uphold", locals: {knowledge_sprout: @knowledge_sprout}

| Calculating a simple decimal in rails console using postgresql Posted: 31 Dec 2016 04:01 PM PST Ok...I think I'm missing something very obvious here but haven't been able to google myself through this solution. I have two simple rails methods that calculate the number of up votes and down votes. They will always return a fraction because i'm trying to show a percentage (up_vote_count / votal_vote_count). I open the rails console and run the following: y = @somespecificrecord
then... y.up_vote_count
This returns 1 as is expected y.down_vote_count
This returns 1 as is expected y.total_vote_count
This returns 2 as is expected. However, when I run in the console... y.up_vote_count / y.total_vote_count This returns 0 when it should return .50. I've been reading about floats/integers/decimals, etc and I do see this in the schema on the model i'm working from: t.float "value", default: 0.0
Is this my problem?...and if so what do I have to do to allow myself to do a simple formula like the one above in rails console that will return the correct decimal rounded to 2 digits (i.e, .50 in this case above). I don't know if I want to run any migrations to change data types because this is a gem (& as a beginner I tend to stay away from customizing code from any gems I'm using). Is there another way? something small i'm missing hopefully? UPDATE: I'm learning decimals are slower than floats also, so is there any way to accomplish this with continuing to use t.float "value", default: 0.0 thanks for any help. |
| ActionCable issues on app upgraded to Rails 5 Posted: 31 Dec 2016 04:04 PM PST ActionCable is not working on my app that I just upgraded to Rails 5.0.1. I generated a channel with rails g channel. When I run the server I don't see any line in the log that indicates ActionCable is doing anything. On the client side I get App is not defined I created a new app with rails new and ActionCable works fine in it. I compared all the relevant files in and they look the same in both apps. Are there some gems that I need to install in my upgraded app that would be installed by default in a new Rails 5 app? I checked and I have actioncable. |
