| rails csv import ram consumption issue postgres Posted: 19 Aug 2016 07:37 AM PDT I have implemented the CSV import in my rails app. Now the issue is ram consumption is too high. The total no. of records in my CSV is around 3600 and my ram consumption is going around 600MB - 800MB and it doesn't even get flushed after coming out of the import method. I can see similar issue in roo issue list https://github.com/roo-rb/roo/issues/179 I am working on Rails 4.2.6 Ruby 2.2.4 code: data = CSV.foreach(file.path, headers: true) data.each do |row| Model.create(row ....) ......... end
Initially my ram consumption is: GetProcessMem:0x7fd3083b2a30 @mb=204.52734375
Before getting out of the method: GetProcessMem:0x7fd30ae1a7a0 @mb=289.60546875
After completing and redirecting to home page: GetProcessMem:0x7fd2fb3913d8 @mb=629.61328125
With this much ram consumption, I cannot deploy it on heroku. This consumed ram doesn't even gets cleaned up, have to restart my server for it. Anyone up with a solution or any alternative way to import csv. |

| Model Structure & has_many Association Migrations Posted: 19 Aug 2016 07:22 AM PDT I'm trying to set up models in such a way that Users can create Lessons and then other users can sign up for them. Right now my models are set up like this: class Lesson < ApplicationRecord belongs_to :teacher, class_name: 'User' has_many :students, class_name: 'User' end class User < ApplicationRecord has_many :lessons has_many :students, :through => :lessons end
I want to be able to access the users signed up for a lesson by @lesson.students for example. I'd also like to be able to get all the lessons that a student is participating in (can't really see how I'd do this with my current set up). Are my model associations right for how I'd like to use them? If so, how can I create the migrations to add the necessary references to my database models? |
| How can I get a mixed hash of has_many relationships Posted: 19 Aug 2016 06:55 AM PDT The User table has_many posts, seeds & areas. I'm trying to get these all in the same array so I can loop through them ordered by the date they were created. I have seen .reflect_on_association which appears to do this.. however I have more has_many associations which I don't want to be in the array. Any thoughts on the best way to do this? I'm trying to avoid getting them all separately like: posts = user.posts seeds = user.seeds areas = user.areas Hash... posts, seeds, areas
Can I do something like: posts_seeds_areas = user.reflect_on_association(:has_many, {Post, Seed, Area})
Is what I'm suggesting possible? |

| Rails 5 crash in .erb file but only when running on server Posted: 19 Aug 2016 06:29 AM PDT so i have this code in my erb file: <% a = ["Apple","Orange","Banana","Carrot","Turnip","Rabbit","Lion"] %> <% arr = @things.where(:active => 1).sort_by{|el| a.index(el[:name])}%> <% for product in arr %>
and its crashing on line 2 with this error: comparison of Fixnum with nil failed
I replaced it with this: <% arr = @things.sort_by{|el| a.index(el[:name])}%>
and its still crashing... when i change the entire code block with this: <% for thing in @things %>
the crash goes away. its odd because it runs fine locally. |
| Alter regex markup to not separate float numbers (like 2.0) Posted: 19 Aug 2016 07:31 AM PDT I was looking for a solution to a regex problem in Rails I had and an answer on a separate question lead me 90% of the path to the answer. Basically, what I would like to do is to have a ruby/rails script that will format a messy text in terms of capitalizing every letter after a "./,/!/?". This code by "Mark S" ng = Nokogiri::HTML.fragment("<p>hello, how are you? oh, that's nice! i am glad you are fine. i am too.<br />i am glad to have met you.</p>") ng.traverse{|n| (n.content = n.content.gsub(/(.*?)([\.|\!|\?])/) { " #{$1.strip.capitalize}#{$2}" }.strip) if n.text?} ng.to_s
The only issue I have with this code, and it is a big issue, is that the code adds a space in between float numbers like "2.0", making a text like: there is a cat in the hat.it has a 2.0 inch tail! isn't that awesome?!I think so.
Become There is a cat i the hat. It has a 2. 0 inch tail! Isn't that awesome?! I think so.
where I obviously want it to be: There is a cat i the hat. It has a 2.0 inch tail! Isn't that awesome?! I think so.
Any suggestions on how to alter this text, for example so that any "." will be ignored by this code? |
| Get custom value in view hook Posted: 19 Aug 2016 07:15 AM PDT I added a custom value in the user form in my redmine. It's a boolean value (a checkbox). My custom value's id is 8 I'm trying to get it's value in a view hook (view_issues_show_description_bottom) So with this code in my hook class : cv = CustomValue.where('custom_field_id = 8').first context[:cv] = cv
And this code in my .view file <% if cv.value == "1" %>
At the beginning it worked, but then after that i added other fields, and it's not working anymore. I guess there is a better way to get the custom value from the current user ? I'm a complete beginner with ruby so i really don't know how to fix this. Thx a lot |

| Mirroring Heroku Timeout parameters in local development app Posted: 19 Aug 2016 05:39 AM PDT I have a rails app that compiles a large set of PDF reports by making calls to salesforce database. As it's run once in a blue moon I'm hoping I can sneak this in on the Free Tier and convince the holders of purse-strings to upgrade to hobby once I can demonstrate it. Currently the app works in production but fails (pretty sure it's a h12) after a consistent interval when in production on Heroku. This will be because I haven't got around to implementing the heavy lifting as a background-job/delayed-job yet, will follow along here and here. I'm new to the background job API, so ideally I'd like to be able to set up RSpec tests and prod around myself with my development app set up to mirror production constraints of the heroku app. So, questions: - Should I be trying this? Mirroring production constraints in my development app seems like a good way to learn and test this stuff locally... but I have an itching idea they're separate for a reason and I'm violating some boundary or missing a more obvious solution (test on production... but locally?)
- How best to mirror the Heroku production constraints (ideally I'd want to be able to test locally if a process seems to be regularly outstripping a Rack or Puma timeout window or worse going over memory limits (I have some pretty heavy objects in there!) and fail in a comparable way so I can work on how to handle/mitigate such failures.
- I presume this problem is more universal (constraints of production server differ from dev) than just cos I want to generate PDFs whilst being a cheapskate on Heroku's free tier... does anyone have any good recommendations/reading on best pratice for testing and minimising failures when pushing to production? (I've already run into precompiling assets fun, I'm sure there's other landmines out there somewhere...)
Many thanks! |
| RabbitMQ Timeout::Error: IO timeout when reading 7 bytes Posted: 19 Aug 2016 06:46 AM PDT I use Ubuntu14.04, Rail 5, RabbitMQ (server 3.6.5), Bunny 2.5.1 I implemented Rabbit to servise, and tried to test it. I wrote next ruby script: def rabbit_test s_time = Time.current 10_000.times do |n| Mq::RabbitService.new('test_queue').publish(n.to_s) end p "###############################" p "RabbirMQ Diff: #{Time.current - s_time}" p "###############################" end
where Mq::RabbitService service include initialize Bunny, connection, creating queue etc it other terminal I run Mq::RabbitService.new('test_queue').subscribe
for start it works good, but I can push ONLY 827 messages (I don't know why exactly 837, but it is constantly same number). After that my publisher raise error: [8] pry(main)> rabbit_test E, [2016-08-19T15:17:02.445820 #6409] ERROR -- #<Bunny::Session:0x6fb39858 oleg@192.168.1.67:5672, vhost=/, addresses=[192.168.1.67:5672]>: Got an exception when receiving data: IO timeout when reading 7 bytes (Timeout::Error) Timeout::Error: IO timeout when reading 7 bytes from /home/oleg/.rvm/gems/ruby-2.3.1/gems/bunny-2.5.1/lib/bunny/cruby/socket.rb:52:in `rescue in read_fully'
Also I've tried: add new user with admin privileges, tried add IP instead localhost address (like 192.168.0.11) result the same. EDITED I use my service for RabbitMQ connection Mq::RabbitService gist BUT def rabbit_test s_time = Time.current 1_000.times do |n| connection = Bunny.new(host: '192.168.1.67', port: 5672, user: 'oleg', password: '111111').start channel = connection.create_channel channel.queue('queue_name', auto_delete: true) exchange = channel.default_exchange exchange.publish(n.to_s, routing_key: 'queue_name') channel.close end p "###############################" p "RabbirMQ Diff: #{Time.current - s_time}" p "###############################" end
doesn't work too Maybe someone know what I do wrong? Thanks |
| Michael Hartl Rails Tutorial 4, micropost Partial and instance variables Posted: 19 Aug 2016 07:22 AM PDT following his tutorial, the home page from Static-Pages Controller renders a partial_form: <%= render 'shared/micropost_form' %>
StaticPagesController.rb def home @micropost = current_user.microposts.build #for the form_form @feed_items = current_user.feed.paginate(page: params[:page]) end
Then, in the MicropostController.rb, an action for the partial micropost_form is declared: class MicropostsController < ApplicationController def create @micropost = current_user.microposts.build(micropost_params) if @micropost.save flash[:success] = "Micropost created!" redirect_to root_url else @feed_items = [] render 'static_pages/home' end end end
Notice how, if micropost_form success, it gets redirected static_pages's index view, but, if failed, it renders static_pages home view (which also keeps the params in the form, so the user doesn't have to writype all the data), BUT, it needs to initialize static_pages's home controller instance variables (namely, feed_items). Now, suppose StaticPages Controller's home has a long list of complex instances variables, how can MicropostController render (to keep form data upon failure) static_pages/home without creating that many instance variables? note: this question is related to my previous one,but I wanted to understand this basic example before. |
| Rails 5 enum inside model's Concerns generates NameError: uninitialized constant Posted: 19 Aug 2016 06:44 AM PDT Rails 5 here. I tried without luck to load a concern inside my User model (devise model). The include Levelable works without any problem on other models. Do I have to configure a special config/helper/initializer regarding this special model to make it work? Model concern Levelable is used by models User and Client #models/concerns/levelable.rb require 'active_support/concern' module Levelable extend ActiveSupport::Concern included do enum level: { beginner: 0, intermediate: 1, advanced: 2, very_advanced: 3 } end end
And the model (shortened for readability) #models/user.rb class User < ApplicationRecord # Include default devise modules. Others available are: # :confirmable, :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :confirmable include Levelable acts_as_messageable end
This setup result is a: NameError: uninitialized constant User::Levelable Same error happens on Client model so I guess something is not working with my concerns load. I already tried to autoload the path inside config/application.rb without any change. I can not figure out how to make the load of the Concerns works, any help would be great. Thank you ! |

| How to combining two search parameters in Rails Posted: 19 Aug 2016 04:34 AM PDT I am just getting into Rails and want to preform a simple search FROM destination TO destination. I have the basic search functionality working and connected to the database but when I choose FROM and TWO the output is combined and I get all transports FROM the specific text and all transports TO the specific text. I want to filter them and only have the ones that go FROM TO. Here is what I have so far. class Transport < ApplicationRecord def self.searchfrom(searchfrom) where("strtloc LIKE ?", "%#{searchfrom}%") end def self.searchto(searchto) where("endloc LIKE ?", "%#{searchto}%") end end
I basically want to add AND in between the two parameters but I am stuck. This is my transports_controller.rb if params[:searchfrom] @transports = Transport.searchfrom(params[:searchfrom]) else @transports = Transport.all end if params[:searchto] @transports = Transport.searchto(params[:searchto]) else @transports = Transport.all end
I also want the ability to only select FROM. So I cant really do a simple AND statement. But one at a time. Any help apreciated! |
| how to do form_for with dynamic, multi-level hash? Posted: 19 Aug 2016 04:48 AM PDT I have a class with dynamic content. I initialize it in the new method in the controller: def new @person = Person.new(:info => {:first_name => "Joe", :last_name => "Smith"}) end
Now, disregard the fact that I'm manually coordinating the structure of :info between my controller and form (I have a meta configuration stored in another class, I'm simplifying this to seek abstract help), how do I set up a field for first_name and last_name? This fails: <%= form_for @person do |f| %> <% f.text_field :info[:first_name] %> <% end %>
It fails with no implicit conversion of Symbol into Integer

| Rails - Asking for permission for access to specific infos from User in Oauth provider server? Posted: 19 Aug 2016 04:15 AM PDT I have an idea that I am working on and it requires to have my own Opro (oauth provider) server set up. I followed this article which is great and explains clearly. - https://www.sitepoint.com/authenticate-all-the-things-with-opro-the-basics/ Once the user logs in the opro server, they are asked that a particular application is trying to access info and what type of permission user wants to give to app, i.e. to read or write that data. I want user to be able to select what info application can use. For example, user logs in opro server, they are shown like "Application wants to access your email, contact number, address", each of the attributes as individual checkbox. So I may want to share my email but not other infos. I tick mark just email and proceed ahead and the application works with that. (It would be great if I could make this work not just with user's attributes but across relationships). Please let me know if I am not clear. |

| Simple form not submitting to database Posted: 19 Aug 2016 04:15 AM PDT I'm building a simple online shop for practice and want to track order histories, at the moment I'm getting the user to submit but the shipping address and order history, later I'll upgrade order history to be a hidden field. The problem is that I can't get the simple form to submit anything to my database. My form looks like this: <p class="text-center"> congratulations your order is almost complete, please fill out the form below to place your order or <%= link_to "browse other products.", root_path %> </p> <%= simple_form_for @placeorder, html: { multipart: true } do |f| %> <%= f.error_notification %> <div class="form-inputs" > <%= f.input :shipping_address, label: false, placeholder: 'Shipping address', input_html: { class: 'input-lg', required: true } %> <%= f.input :order_history, label: false, placeholder: 'order_history', input_html: { class: 'input-lg', required: true } %> </div> <div class="form-actions"> <%= f.button :submit, "Confirm order" %> </div> <% end %>
My place order controller looks like this: class PlaceOrdersController < ApplicationController def new current_order.order_items.each do |order_item| @last_item_name = order_item.product.name end @placeorder = PlaceOrder.new @order = current_order.order_items end def create @placeorder = PlaceOrder.create(place_order_params) p "HELLO #{@placeorder}" if @placeorder.save flash[:success] = "You've made your order" redirect_to root_path else flash[:alert] = "Something went wrong, check the form and submit your order again" render :new end end private def place_order_params params.require(:place_order).permit(:shipping_address, :order_history) end end
My routes.rb looks like this: Rails.application.routes.draw do resources :products resources :checkout resources :place_orders resource :cart, only: [:show] resources :order_items, only: [:create, :update, :destroy], defaults: { format: 'js' } root to: "products#index" devise_for :users, :controllers => { registrations: 'registrations' } end
I have other forms that are working fine and they look the same. Any help would be greatly appreciated. |

| Get all included Active Record objects of collection Posted: 19 Aug 2016 03:54 AM PDT Is there any way of getting all objects, included in Active Relation query? Something like this: def index @items = Item.all.includes(:comments) @comments = @items.comments // No such method for AR Collection :( end
The obvious way to get all the items in this case is: @comments = @items.map(&:comments).flatten.uniq
Thanks to using .includes(:comments) there should be no N+1 queries, but I worry about the performance of this code. Are there any built-in or more effective ways of getting all included records of collection? |
| Rails - Flexslider, flexAnimate dynamically Posted: 19 Aug 2016 03:18 AM PDT I am using flexslider as; <div class="car-detail-slideshow2" data-target="#modalFillIn" data-toggle="modal" id="car_popup_pictures"> <% @car.pictures[0..1].each_with_index do |p1, i| %> <div class= "car-show-pop col-sm-6 no-padding cursor-pointer" data-index= "<%= i %>"> <%= image_tag p1.image_url(:slider).to_s %> </div> <% end %> <% @car.pictures[2..4].each_with_index do |p2, i| %> <div class= "car-show-pop col-sm-4 no-padding col-sm-height cursor-pointer" data-index= "<%= i + 2 %>"> <%= image_tag p2.image_url(:slider).to_s %> </div> <% end %> </div>
which creates pictures and their indexes, when I click I would like flexslider to open from the data-index. So far I tried to add it to start function on click of the div no luck Flexslider works, but it starts from the index of 0, does not matter, which data-index I pressed. How can I fix this? <script type="text/javascript"> $(function(){ $('#modalFillIn').on('shown.bs.modal', function () { $('#carousel2').flexslider({ animation: "slide", controlNav: false, animationLoop: false, slideshow: false, itemWidth: 110, itemMargin: 5, directionNav: false, asNavFor: '#slider' }); $('#slider').flexslider({ animation: "fade", controlNav: false, animationLoop: false, slideshow: false, touch: true, keyboard: true, sync: "#carousel2",s start: function(slider){ $('body').removeClass('loading'); $('.car-show-pop').click(function(event){ event.preventDefault(); var pos = parseInt($(this).data('index'), 10); slider.flexAnimate(pos, true); }); } }); }); }); </script>

| Determine which link (on same page) was used? Posted: 19 Aug 2016 02:42 AM PDT I have a page with two links to an introduction/registration page. We want to show different content based on which link the user uses. They appear in different contexts on the same page, and we would like to tailor the message on the registration page to that context. For SEO purposes I was told not to change the URL. I'm using rails. Since the incoming user will have the same referrer regardless of which link was clicked, what is the best way to know which link was used to get to my page? Is it possible in a practical way without altering the URL? |
