| Reduce the execution time of jobs of sidekiq Posted: 25 Mar 2016 06:59 AM PDT I am currently working on an app which involves syncing of contacts on rails server. I am using redis server and sidekiq for performing contact syncing in the background. My database is mongodb and I am using mongoid gem as ORM. Workflow is a follows: - Contacts on the phone are passed to the rails server through app and then on the rails server, it is queued in the redis server.
- Now cron job triggers sidekiq which connects to redis and completes the job.
One Job of sidekiq is as follows: - it has array of contacts(size upto 3000).
- It has to process each of these contacts. By processing I mean make insert queries to DB.
Now the problem is that sidekiq takes insane amount of time to complete the job. On average it takes 50-70 sec to complete the job. Following are the relevant files sidekiq.yml # Sample configuration file for Sidekiq. # Options here can still be overridden by cmd line args. # sidekiq -C config.yml :verbose: true :concurrency: 5 :logfile: ./log/sidekiq.log :pidfile: ./tmp/pids/sidekiq.pid :queues: - [new_wall, 1]#6 - [contact_wall, 1]#7 - [email, 1]#5 - [gcm_chat, 1]#5 - [contact_address, 1]#7 - [backlog_contact_address, 5] - [comment, 7] - [default, 5]

How can I speed up the processing of jobs? I tried with permutation of increasing concurrency of sidekiq in sidekiq.yml and pool of mongoid.yml, but no help. How do whatsApp and other messaging apps deal with contact syncing? If some other info is required, please ask. Thanks. |

| redirect_to an instance variable does not work in Rails 4 Posted: 25 Mar 2016 07:00 AM PDT I'm completely new to Rails. Just started from *http://guides.rubyonrails.org/getting_started.html While trying I'm stuck with redirect_to problem like below error - NoMethodError in SwversionsController#create undefined method `sw_versions_url' for #<SwversionsController:0xa38d158> Rails.root: C:/Sites/edisonprojectmanagement Application Trace | Framework Trace | Full Trace app/controllers/swversions_controller.rb:19:in `create'*
This error occurs after clicking submit button. I found the model is working fine and data is saved in my postgresql database. I think problem is with my redirect_to method. My SwVersionsController code looks like - class SwversionsController < ApplicationController def index end def show @swversion = SwVersion.find(params[:id]) end def new end def create @swversion = SwVersion.new(swversion_params) @swversion.save redirect_to @swversion end private def swversion_params params.require(:swversion).permit(:sw_version, :description) end end

| Creating a tram timetable with ruby on rails Posted: 25 Mar 2016 06:35 AM PDT I am trying to create an application which lists tram times for a station to the next. I have been given large amounts of data in an excel spreadsheet. The data consists of Lines (EAST, WEST, NORTH, SOUTH). Each of these lines include a list of stops(stations). Each of the stations consist of a massive list of times from day to night. The system should take a look at current time and render out all lines, stations and times based on many different queries (mainly searching start to end stations). The excel table is laid out for only ONE line like: Station 1 07:00 07:30 08:50 ... Station 2 07:15 07:45 08:55 ... Station 3 07:18 08:00 09:05 ...
think of the stations as stops. The distance between the first journey from Station 1 to Station 2 is 15 minutes. Then the next tram from station1 starts at 7:30. There are many of these excel documents represented as lines. I am using mongoid in rails so my models are like: class Line include Mongoid::Document include Mongoid::Timestamps embeds_many :stations field :line, type: String end class Route include Mongoid::Document include Mongoid::Timestamps embedded_in :station field :time, type: Time end class Station include Mongoid::Document include Mongoid::Timestamps embeds_many :routes embedded_in :line, inverse_of: :stations field :name, type: String end
A line has many stations, a station belongs to line. A Station has many routes,a route belongs to station. I know I can import the excel data as it is large but i am having a little difficulty trying to work with these models. How would I be able to store this data is this way and later query based on my requirement or would I have to create my model like line1, line 2, line 3. or am I right? |
| ruby on rails regexp or ends_with Posted: 25 Mar 2016 06:58 AM PDT I'm trying to prevent users from overdoing certain actions. My problem is that I don't know what the best way is to check if the path of the action matches with what I define in the YAML file. As I see it could be either regex or something like ends_with method. At the moment I have the following half ready code. I'm not sure if I should define the paths in the YAML the way I currently do and also not sure if I call a proper comparison in rack_attack.rb. Could somebody help me out and explaining me why his/her recommended solution is the best here? YAML: logins_ip: limit: 5 period: 30 path: /users/sign_in post_comment_creation: limit: 5 period: 45 # Full route is /posts/:post_id/post_comments but post_id not required # since I wanna prevent users from commenting more than 5/45sec to all the # posts. Yet I may could use some regex that matches any number. path: /post_comments messages_creation: limit: 10 period: 10 # Here I need this exact route since I wanna prevent users from # messaging more than 10/10sec in a given conversation path: conversations/:conversation_id/messages default: period: 60 limit: 10 method: POST

| How to pass data-attribute from a button to it's corresponding modal Posted: 25 Mar 2016 06:37 AM PDT In my rails app, I have a view with some images. <div class="item-images"> <div class="row"> <% @user_item.user_item_images.each_with_index do |image, index| %> <% if (index + 1) % 5 == 0 %> </div><div class="row"> <% end %> <div class="image-container"> <a class="fancybox" rel="group" href="<%= image.picture.large.url %>"><img class="img-thumbnail img-circle" src="<%= image.picture.thumb.url %>" alt="" /></a> <% if @user.eql?(current_user) && @user_item.primary_image_id != image.id %> <button class="btn btn-xs btn-danger delete-image" data-id="<%= image.id %>" data-toggle="modal" data-target="#delete-image-modal"> <i class="fa fa-trash-o fa-lg"></i> </button> <% if @user_item.primary_image_id != image.id %> <button class="btn btn-xs btn-info make-primary" data-id="<%= image.id %>" data-toggle="modal" data-target="#make-primary-modal"> <i class="fa fa-thumb-tack fa-lg"></i> </button> <% end %> <% end %> </div> <% end %>
As you can see I have two buttons associated with each image. The corresponding modals: <!-- Delete Image Modal --> <div id="delete-image-modal" class="modal" tabindex="-1" role="dialog" aria-labelledby="delete-image" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button> <h4 id="delete-image">Are you sure you want to delete this image?</h4> </div> <div class="modal-footer"> <button class="btn btn-default" data-dismiss="modal" aria-hidden="true">Cancel</button> <%= link_to 'Delete', '', method: :delete, :class => 'btn btn-danger' %> </div> </div> </div> </div> <!-- Make Primary Modal --> <div id="make-primary-modal" class="modal" tabindex="-1" role="dialog" aria-labelledby="make-primary" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button> <h4 id="make-primary">Are you sure you want to make this the primary image for your item?</h4> </div> <div class="modal-footer"> <button class="btn btn-default" data-dismiss="modal" aria-hidden="true">Cancel</button> <%= link_to 'Make Primary', make_primary_path(????), :class => 'btn btn-info' %> </div> </div> </div> </div>
The make_primary_path brings us to a controller action which changes an attribute of the modal's associated image: def make_primary @user_item = UserItemImage.find(params[:user_item_image_id]).user_item @user_item.update_attributes(primary_image_id: params[:id]) flash[:notice] = "primary image set" redirect_to :back end
The route for this action: get 'user_item_images/:user_item_image_id/make_primary', to: 'user_item_images#make_primary', as: :make_primary
My problem is generating the link in the "Make Primary Modal". How do I get the data-id from the button and use that in the link_to helper? |

| Use RSpec let(:foo) across examples Posted: 25 Mar 2016 04:56 AM PDT I'm using let(:foo) { create_foo() } inside my tests. create_foo is a test helper that does some fairly time expensive setup. So everytime a test is run, foo is created, and that takes some time. However, the foo object itself does not change, I just want to unit test methods on that object, one by one, seperated into single tests. So, is there a RSpec equivalent of let to share the variable across multiple examples, but keep the nice things like lazy loading (if foo isn't needed) and also the automatic method definition of foo so that it can be used in shared examples, without referencing it with a @foo? Or do I have to simply define a def foo create_foo() end

| rspec and apartment gem - switching subdomain host in feature spec Posted: 25 Mar 2016 04:11 AM PDT For the last several hours i have been fighting with rspec feature test. I am using apartment gem for subdomains . User can create account with subdomain field. Then he is redirected to http://user_subdomain.lvh.me/admin. This work very well in my development database. Problem comes from my feature rspec test. Below is my code scenario 'User can sign up' do visit root_path click_link 'Create account' fill_in 'Email', with: 'test@test.com' fill_in 'Subdomain', with: 'test' fill_in 'Password', with: 'test1234' fill_in 'Confirm Password', with: 'test1234' click_button 'Create' Capybara.app_host = "http://test.lvh.me" Capybara.always_include_port = true expect(page).to have_content('Hello from the dashboard.', wait: 5) Apartment::Tenant.drop('gabinettttt') end
This gave me this error: ActionController::RoutingError: No route matches [GET] "/admin"
I know that this problem comes from Capybara switching host and only happen inside my test database. What is the proper way to test sign up user with subdomain? |

I referred Rails 4 Devise 3.1.1 ActionController::UnknownFormat in Devise::RegistrationsController#new and found the idea to remove the resource_name and it seems to work. However, i cant understand why. Thanx in Advance |

| Rails, Installed Gem version and Gemfile.lock version Posted: 25 Mar 2016 05:07 AM PDT I have a problem. Gemfile.lock is always committed if bundle is updated. And today, when I deploy web application, I see this error message, Could not find jwt-1.5.3 in any of the sources
jwt-1.5.2 is installed in deployed server at shared gem path.
I think bundle install new jwt-1.5.3 gem because the specified version (1.5.3) in Gemfile.lock and installed version (1.5.2) is not equal. Why cannot bundle install jwt gem? Should bundle install that gem if Could not find jwt-1.5.3? |
| ngFileUpload with rails Posted: 25 Mar 2016 04:38 AM PDT I wanted to upload file when i submit the form. I am using ngFileUpload at the front end and server is on rails. Following is the code the i have written : <form name="form" ng-submit="submit()"> <input type="text" ng-model="data.username"/> <input type="text" ng-model="data.address"> <input type="file" id="map" ngf-select ng-model="data.map" name="file" accept="image/*" ngf-max-size="2MB" ngf-model-invalid="errorFile"> </form>
On form submit, i could see the data(on browser console) object containing all the values(including the object of map/image). But when i check on server side, map is showed as {} i.e empty object. Could someone help me resolve the same. |
| Print \n as actual newline in terminal Posted: 25 Mar 2016 02:44 AM PDT In my RSpec email tests I render some text views with newlines: class MyMailer < ActionMailer::Base def email1 @foo = "Hello" @bar = "World" mail(to: "test@example.com", subject: "Foobar") end end
This is the view email1.text.erb <%= @foo %> <%= @bar %>
And this is my test: it 'renders output' do body = MyMailer.email1.body puts body end
When I print the email body in terminal, ruby returns \n instead of an actual newline: Hello\n\nWorld
For debugging purpose it would be nice to have the actual newlines instead of \n printed in my terminal. Is there a way to do this? |
| Rails 4 - Heroku - production errors Posted: 25 Mar 2016 02:14 AM PDT I'm new to coding and learning on the go. I find it difficult to decipher what the heroku logs are telling me.

| How can I dynamically determine which column is passed to friendly_id in order to watch it for changes? Posted: 25 Mar 2016 12:42 AM PDT I'm using the very useful option: # config/initializers/friendly_id.rb # ... config.use Module.new { def should_generate_new_friendly_id? slug.blank? end }
The issue is that I use friendly_id on 3 or 4 different models for which the attribute to watch for a change is differrent. For some it's name, others title. Is there a way to dynamically retrieve the attribute symbol that was passed to friendly_id :title, use: :slugged to prevent this being necessary in models? # app/models/foo.rb class Foo < ActiveRecord::Base # ... friendly_id :title, use: :slugged def should_generate_new_friendly_id? super || title_changed? end end
``` Ideally I'm looking for something like: # config/initializers/friendly_id.rb # ... config.use Module.new { def should_generate_new_friendly_id? slug.blank? || friendly_id_attribute_changed? end }
Can this be achieved? |
