| Rails absolute time from reference + french "ago" string Posted: 12 Jun 2016 06:56 AM PDT I need to reimport some data that was exported using the "ago" stringification helper, in French. I have a reference Time/DateTime date at which the import was done, and from there I need to substract this "time ago" difference to find the absolute time. Eg IMPORT_DATE = Time.parse('Sat, 11 Jun 2016 15:15:19 CEST +02:00') parse_relative_time(from: IMPORT_DATE, ago: 'Il y a 5j') # 'Il y a 5j" = "5d ago" # => Should output sthing like Sat, 6 Jun 2016 (DateTime object) parse_relative_time(from: IMPORT_DATE, ago: 'Il y a 1 mois') # 'Il y a 5j" = "1 month ago" # => 11 May 2016 (it's not big deal if it's 10 or 11 or 12 because of months with odd numbers, just need something approximate)

| Slow activerecord/postgres query not utilizing index Posted: 12 Jun 2016 07:01 AM PDT I have a Messages table with user_id field (string). A query for total unique users is extremely slow with over a million records. Message.where(created_at: start_date..end_date).select(:user_id).distinct(:user_id).count => (120145.6ms) SELECT DISTINCT COUNT(DISTINCT "messages"."user_id") FROM "messages" WHERE ("messages"."created_at" BETWEEN '2016-05-14 04:00:00.000000' AND '2016-06-13 03:59:59.999000')
I have indexes on user_id & created_at, but postgres doesn't seem to use them: Schema add_index "messages", ["user_id"], name: "index_messages_on_user_id", using: :btree add_index "messages", ["created_at"], name: "index_messages_on_created_at", using: :btree
PG Explain QUERY PLAN ----------------------------------------------------------------------------------------------------------------------------------------------------------------- HashAggregate (cost=56111.04..56291.89 rows=18085 width=29) Group Key: user_id -> Seq Scan on messages (cost=0.00..52215.65 rows=1558153 width=29) Filter: ((created_at >= '2016-05-14 04:00:00'::timestamp without time zone) AND (created_at <= '2016-06-13 03:59:59.999'::timestamp without time zone)) (4 rows)
Why are the indexes not used? Any tips for speeding up the query? |

| Rails default model translation files for my language Posted: 12 Jun 2016 05:20 AM PDT Where can I find the translation files used by Rails to translate model-related interpolated strings for my language ? The Rails documentation has some information there, but this is all blabla and what I really want is the default file used by Rails that outputs the default messages I can see. And I'm not talking about model/attributes translation, I also already do that, but what I want is to be able to copy the fr.yml file that contains all the structure for messages. For example the translation My email cannot be blank Mon email doit être rempli(e) # fr translation
Where can I find the (LATEST) files that define "%{attribute} cannot be blank" "%{attribute} doit être rempli(e)"
So that I can redefine them to (for example) "You have to fill %{attribute}" "Vous devez remplir le champ %{attribute}"
I don't even understand where those translations are/where to look at them. I18n ? ActiveModel ? ActiveSupport ? ActiveRecord/Mongoid ? I really want to copy the whole file, because I need to make sure no untranslated strings go through. I am using Rails 5 and Mongoid Edge. BONUS : I'd also like to generate some sample translations based on what my models look like, is there some kind of framework/script that crawls the models, and print an example of every string that can appear given the validations in place, etc. ? |
| How to solve n+1 query issue with includes - Rails Posted: 12 Jun 2016 05:39 AM PDT I'm using the bullet gem to find out what n+1 query problems my app has, and it turns out I have 3 issues: user: Rashed N+1 Query detected Sale => [:shop] Add to your finder: :includes => [:shop] user: Rashed N+1 Query detected Shop => [:malls] Add to your finder: :includes => [:malls] user: Rashed N+1 Query detected Shop => [:categories] Add to your finder: :includes => [:categories] The problem is i'm not really sure how to go about solving the problem using includes because of how my models are associated with eachother. I have 4 models, Sale, Shop, Mall, and Category. These are the associations for my models: class Shop < ActiveRecord::Base has_many :categorizations has_many :categories, :through => :categorizations has_many :mall_shops has_many :malls, :through => :mall_shops has_many :sales, dependent: :destroy end class Sale < ActiveRecord::Base belongs_to :shop end class Mall < ActiveRecord::Base has_many :mall_shops has_many :shops, :through => :mall_shops has_many :sales, :through => :shops end class Category < ActiveRecord::Base has_many :categorizations has_many :shops, :through => :categorizations has_many :sales, :through => :shops end
In my Sale index page, im displaying all the Sales records, and each sale record belongs to a shop, and each shop has many categories and many malls. For every Sale record displayed im iterating through all the malls and categories that that Sale's Shop belong to (for filtering purposes). This is the relevant code in my Sale index page: <% @sales.each do |sale| %> <div class="<% sale.shop.malls.each do |m| %> mall<%= m.id %><% end %><% sale.shop.categories.each do |c| %> category<%= c.id %><% end %>"> . . end
And my Sale's Controller: class SalesController < ApplicationController def index @malls = Mall.all.order('name ASC') @categories = Category.all.order('category_type ASC') @shops = Shop.all @sales = Sale.where('offer_end >= ?', Date.today).order('offer_end ASC') end end
So what would be the best way to solve the n+1 query issue I have? to get a better idea of my app this is the website im building: www.shopwatchkw.com |
| Rails String in View with whitespaces Posted: 12 Jun 2016 05:39 AM PDT I'm trying to show a string with xml content (correct with whitespaces etc.) in a rails view. My Controller action read a xml file and put this content into a string. For example @xml_content = " <main> <children> <a> </a> <b> </b> </children> </main> "
Then I get this string from my controller and want to show this xml content in a view. <%= @xml_content %>
But when I print this string in the view all whitespaces get lost and I get something like this: <main><children><a></a><b></b></children></main>
Printing the same string in the console with "puts @xml_content" create the correct output. What can I do to show this xml content with all whitespaces in the view? EDIT: Controller: @file = File.open(@xml_device_description.get_file_path) @xml_content = Nokogiri::XML @file

| I need to create two objects in same form (rails) Posted: 12 Jun 2016 04:52 AM PDT so please imagine a form for a car reservation, the form contains both some client information(name, age, city..) and also the reservation informations(start_date, end_date...). So obviously, i need to create in the same form a client first, based on the informations and then the reservation which is related to the created client: class Client < ActiveRecord::Base has_many :reservations end
. class Reservation < ActiveRecord::Base belongs_to :client belongs_to :voiture end
Here is what i did until now(bad way). The reservation informations start with f.text_field, and the client informations only with text_field(very bad way yes :( ) <%= form_for([@voiture, @voiture.reservations.new]) do |f| %> <div class="row"> <div class="col-md-12 price_tag"> <span><%= @voiture.price %>Dhs</span> <span class="pull-right">Par jour</span> </div> </div> <div class="row"> <div class="col-md-6"> <label>Nom</label> <%= text_field :nom, readonly: 'true', placeholder: 'Nom', class: 'form-control' %> </div> <div class="col-md-6"> <label>Prenom</label> <%= text_field :prenom, readonly: 'true', placeholder: 'Prenom', class: 'form-control', disabled: 'true' %> </div> </div> <div class="row"> <div class="col-md-6"> <label>CIN</label> <%= text_field :cin, readonly: 'true', placeholder: 'CIN', class: 'form-control' %> </div> <div class="col-md-6"> <label>Age</label> <%= text_field :age, readonly: 'true', placeholder: 'Age', class: 'form-control', disabled: 'true' %> </div> </div> <div class="row"> <div class="col-md-6"> <label>Ville</label> <%= text_field :ville, readonly: 'true', placeholder: 'Ville', class: 'form-control' %> </div> <div class="col-md-6"> <label>Télephone</label> <%= text_field :telephone, readonly: 'true', placeholder: 'Telephone', class: 'form-control', disabled: 'true' %> </div> </div> <div class="row"> <div class="col-md-6"> <label>Email</label> <%= text_field :email, readonly: 'true', placeholder: 'Email', class: 'form-control' %> </div> </div> <div class="row"> <div class="col-md-6"> <label>Check In</label> <%= f.text_field :start_date, readonly: 'true', placeholder: 'Start Date', class: 'form-control' %> </div> <div class="col-md-6"> <label>Check Out</label> <%= f.text_field :end_date, readonly: 'true', placeholder: 'End Date', class: 'form-control', disabled: 'true' %> </div> </div> <%= f.hidden_field :voiture_id, value: @voiture.id %> <%= f.hidden_field :prix, value: @voiture.prix %> <%= f.hidden_field :total, id: 'reservation_total' %> <%= f.submit "Book Now", id:"btn_book", class: "btn btn-primary wide", disabled: 'true' %>

| Rails deploy to subdomain x or y depending on environment variables Posted: 12 Jun 2016 04:01 AM PDT I have a Rails website mounted on an autoscaling AWS EC2 group, with Passenger/Apache. The deployment is done using Capistrano, I am getting the list of all the servers and deploying to each of them from a bastion host. I need to be able to switch the subdomain I want to release to using environment variables, eg I should be able to deploy either to www.mysite.com or prod.mysite.com, by simply setting an environment variable. This is done on the Rails/Capistrano side. I am using capistrano_env to pull the deploy host and do something like env.add 'HOST', deploy_host The problem is about URLs redirections. My apache file specifies the valid hosts as serverName + alias (www, prod), however ideally, the client would be redirected to only www or prod depending on which site he has typed in his browser. Here is my current vHost file on port 80 (port 443 is fine) <VirtualHost *:80> ServerName "www.example.com" ServerAlias "production.example.com" DocumentRoot "/var/www/mysite/current/public/" Redirect "/" "https://production.example.com/" </VirtualHost>
The most important problem that needs to be tackled here: Redirect "/" "https://production.example.com/"
The redirection should be done to either https://www or https://prod depending on the URL typed in the client's browser (if the user types http://www, he will currently be redirected to https://prod which is bad) I was wondering how to best tackle the problem - Using mod_rewrite ? I've heard bad things about that...
- Rails app redirection ? Basically if the app was deployed to www, then environment HOST variable will contain
https://www.example.com so maybe we can intercept every request and redirect if the request host is different from the Rails routing side. What do you think ? I am not using deployment solutions like Chef for lack of time/existing code, but I am definitely considering to switch to something like that when there's time. In the meantime I need to find not-so-dirty hacks, that still lets me deploy with one command. |
| AngularJS routing with Rails Posted: 12 Jun 2016 03:55 AM PDT I begin to use AngularJS with my Rails application but when i tried to implement my route providers with Angular, it's not working and Rails view is displayed instead of my template. routes.rb : root 'tutorials#index'

| Bootstrap flash alert CSS not working correctly in mobile screen Posted: 12 Jun 2016 04:22 AM PDT I am currently building a Rails app. In my app, I show flash message using Bootstrap's CSS on alert. I am not fully using Bootstrap's CSS but adding only related to alert in my app due to overlap in CSS. CSS for flash works fine for normal desktop screen. It's position is centered and fixed. Image below: 
However, when I populate the flash on mobile screen (lesser than 500px), then it is off-centered to left no matter what I do. Image below:  I am confused why this is happening. Just like the descktop screen, I would like to fix the position of flash in mobile screen and always populate on a same place. Following is the view code I have for the flash <div id="flash-message-wrapper"> <% flash.each do |type, message| %> <div class="alert <%= alert_class_for(type) %> alert-dismissible fade in"> <button type="button" class="close" data-dismiss="alert"> <span aria-hidden="true">×</span> <span class="sr-only">Close</span> </button> <%= message %> <% end %> </div>
The CSS for this code is : .alert { padding: 15px; margin-bottom: 20px; border: 1px solid transparent; border-radius: 4px; } .alert h4 { margin-top: 0; color: inherit; } .alert .alert-link { font-weight: bold; } .alert > p, .alert > ul { margin-bottom: 0; } .alert > p + p { margin-top: 5px; } .alert-dismissable, .alert-dismissible { padding-right: 35px; } .alert-dismissable .close, .alert-dismissible .close { position: relative; top: -2px; right: -21px; color: inherit; } .alert-success { color: #3c763d; background-color: #dff0d8; border-color: #d6e9c6; } .alert-success hr { border-top-color: #c9e2b3; } .alert-success .alert-link { color: #2b542c; } .alert-info { color: #31708f; background-color: #d9edf7; border-color: #bce8f1; } .alert-info hr { border-top-color: #a6e1ec; } .alert-info .alert-link { color: #245269; } .alert-warning { color: #8a6d3b; background-color: #fcf8e3; border-color: #faebcc; } .alert-warning hr { border-top-color: #f7e1b5; } .alert-warning .alert-link { color: #66512c; } .alert-danger { color: #a94442; background-color: #f2dede; border-color: #ebccd1; } .alert-danger hr { border-top-color: #e4b9c0; } .alert-danger .alert-link { color: #843534; } .fade { opacity: 0; -webkit-transition: opacity .15s linear; -o-transition: opacity .15s linear; transition: opacity .15s linear; } .fade.in { opacity: 1; } .close { float: right; font-size: 21px; font-weight: bold; line-height: 1; color: #000; text-shadow: 0 1px 0 #fff; filter: alpha(opacity=20); opacity: .2; } .close:hover, .close:focus { color: #000; text-decoration: none; cursor: pointer; filter: alpha(opacity=50); opacity: .5; } button.close { -webkit-appearance: none; padding: 0; cursor: pointer; background: transparent; border: 0; } .sr-only { position: absolute; width: 1px; height: 1px; padding: 0; margin: -1px; overflow: hidden; clip: rect(0, 0, 0, 0); border: 0; } .sr-only-focusable:active, .sr-only-focusable:focus { position: static; width: auto; height: auto; margin: 0; overflow: visible; clip: auto; } #flash-message-wrapper { position: fixed; top: 50px; left: 50%; margin-left: -250px; width: 600px; } @media (max-width: 500px) { #flash-message-wrapper { position: fixed; top: 50px; right: 50%; margin-right: -250px; width: 300px; } }

| Rspec and Draper : unitialized constant on class name Posted: 12 Jun 2016 03:16 AM PDT On Rails 4 when I execute rspec tests for a decorator I got the following error : /app/spec/decorators/my_decorator_spec.rb:3:in `<top (required)>': uninitialized constant MyDecorator (NameError)
I'm surely missing something but I don't know what. I generate the decorator rails g decorator My
A spec/my_decorator_spec.rb file is generated, with the content : require 'spec_helper' describe MyDecorator do end
Then I test rspec spec/decorators/my_decorator_spec.rb
I didn't add anything in application.rb or spec_helper.rb. The decorator itself works correctly. EDIT It's weirder than I expected. When I test all rspec files, tests inside my decorator spec file are correctly executed. It works : rspec spec/
It doesn't : rspec spec/decorators rspec spec/decorators/my_decorator_spec.rb

| Missing params when save to postgres table column Posted: 12 Jun 2016 04:54 AM PDT All was well before changing my db schema Before: ... t.string :skills, :string ...

Why the "W", in Wordpress is chopped off? Where is "Spree Commerce"? Do I need to add something else on the index column? My controller has the standard permit :skills and nothing in model project.rb |

| Masonry Leaving Whitespaces/Gaps Posted: 12 Jun 2016 02:10 AM PDT Working with masonry.js, it is being populated by rails but is leaving gaps all over the place, I tried two layouts and the pictures and corresponding codes are below.How may I get rid of the gaps indicated by the red arrows.Research states that it may not pack all the way and I should use packery however I've seen examples of masonry filling entire websites like here Example Layout 1  Layout 1 code HTML <div id="restaurants"> <%@restaurant.each do |f| %> <div class="box"> <%= image_tag f.thumbnail.url(:medium)%> </div> <% end %> </div>
Javascript $(window).load(function(){ $('#restaurants').masonry({ itemSelector: '.box', gutter: 0, columnWidth: 1 }); });
CSS .box { height: 320px; width: 320px; margin: 0; }
Layout 2 (which I prefer more) 
All the code remains the same except the css which is just .box { margin: 0; }

The below is what I have so far. <!DOCTYPE html> <html lang="en"> <body> <div class="centered"> <canvas id="drawing_canvas"></canvas> <div id="status_label">loading...</div> </div> <script src="assets/javascripts/p2.min.js"></script> <script src="assets/javascripts/wheel.js"></script>

In console, I see Error: GET [domain]/assets/javascripts/p2.min.js or whatever way I try to load in the javascript (same for the other script following) And looking at resources, from developer tools, I see that those resources somehow don't exist. I've tried reading Rails tutorials and stuff, but I can't seem to find a solution (as for JS being broken, I've tested the JS with just a regular HTML page and it spawned it correctly. Copying that HTML page into the erb somehow creates problems) |

| Shopify API - How can i update product order on Smart Collection with thousands of products? Posted: 12 Jun 2016 12:33 AM PDT I am using Shopify's Ruby Gem to organize Smart Collections in a product store. Essentially I am trying to do a nightly update to the product order on these collections (their sort order is set to manual). The goal is to sort products based on sales data, but also put out of stock items at the end of the list. I managed to write a script that works well on most collections: @scs = ShopifyAPI::SmartCollection.find(:all,params: {limit: 250}) @scs.each do |sc| sc.order(products: @products_in_order) sc.save end
Unfortunately if the collection is larger than a couple hundred products, the URI becomes too long and I get this error: ActiveResource::ClientError: Failed. Response code = 414. Response message = Request-URI Too Large. Is there any way to update product order on large smart collections in an efficient way? Some of my collections have upwards of 1000 products, and I do not want to have to update each "collect" individually as I will be running this script on a daily basis. Any advice is appreciated. |

| Querying a rails db column Posted: 12 Jun 2016 02:31 AM PDT I'm looking for a similar way to query the database like this but struggling how to go about what I want. I'm not just looking for the answer, I also seek where do you find the methods to use. I have searched for postgres db query, rails db query but nothing shows up that matches what I want, or even close. foo = "a,b,c,d" b.bar #=> "b,d,a,f,z" Code shorten for the B Class. B.where('bar like ?', "%#{foo}")
I know that returns nothing. I want if any of foo's value is included in b.bar column, then return it. If foo = "a", I would get a result but foo can have more than one values. Im using Ruby 2.2.5. Rails 5. DB: PostgreSQL Will upgrade to Ruby 2.3 if code is much simple. |
