| Storing chart data in database Posted: 24 Dec 2016 07:06 AM PST I have a web app (Rails) that I want to use to create chart. For now what I do is : - Upload the file containing my data to display
- Store this file and associate it to a model Sample
- When I want to view this Sample I extract the data from the file previously uploaded and create the chart using ChartJS
But I don't really like this solution because the charts are recreated every time, and most of all I want to be able to do some statistics over the time on my charts data and if I keep them into file, it's difficult... Each sample is about ~1000 rows, so it seems "not conventional" to store 1000 new rows every time I create a sample ?
Today I have : Sample ..... id : int ..... attachment : txt file containing the data
Is it OK to change it to : Sample ..... id : int ..... attachment : txt file containing the data ..... chart_data_id : associated ChartData ChartData ..... id : int ..... x : int ..... y : int
I hope I'm clear with my explanations... For example, in my database I would have one Sample whiwh has_many ChartData : Sample(id: 1, attachment: my_file, chart_id: 10) ChartData(id: 10, x: 0, y: 1) ChartData(id: 10, x: 3, y: 2) ChartData(id: 10, x: 5, y: 7) .....

| Why can't I upload a file larger than 1MB to S3 with carrierwave and fog-aws? Posted: 24 Dec 2016 06:56 AM PST I have implemented a file upload for my rails app using carrierwave, S3 and fog-aws. It works well in my local development environment regardless of file size. But when deployed to AWS, file uploads < 1MB succeed, anything > 1MB has resulted in a ERR_CONNECTION_RESET in Chrome and 'The connection was reset' in Firefox. The following is the gems I used. gem 'carrierwave', '~> 1.0' gem 'fog-aws', '~> 1.1'
The following is my carrierwave.rb CarrierWave.configure do |config| config.fog_provider = 'fog/aws' config.fog_credentials = { provider: "AWS", aws_access_key_id: ENV["S3_KEY"], aws_secret_access_key: ENV["S3_SECRET"], region: ENV["S3_REGION"] } config.fog_directory = ENV["S3_BUCKET"] end
The following is my uploader. class AttachmentUploader < CarrierWave::Uploader::Base storage :fog def store_dir "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}" end end

| text classification predefined categories with documents with Omnicat-bayes Posted: 24 Dec 2016 06:35 AM PST I'm using omnicat-bayes to analyse documents (text-classification). With this gem I'm able to create categories and "feed" those with documents. Currently the categories have enough documents in order to be "good enough" to recognize new documents in what category they should be placed in. Now in my Documents controller under the create action are a few steps. - Creating a new Bayes instance
- Creating the categories that will be used
- Taking the pre-documents to train the categories
- Actually training the categories
(all of those steps are under the run_all function) The create action: def create @document = Document.new(document_params) @document.case_id = @case.id if @document.save run_all # Running the classify function on reden aanmelding classify_one = @bayes.classify(@document.reden_aanmelding) document_category = classify_one.to_hash[:top_score_key] # Updating the document category by the top key returned by Bayes @document.update_attribute(:category, document_category) finding_required_records # Training Cees Buddy with the document that got saved @bayes.train(document_category, @document.reden_aanmelding) redirect_to case_path(@case) else render :new end end
Inside the @document.save run_all function (I know this isn't really best practice) I'm creating the four steps named above. Now after the create function is finished the Bayes instance is gone and the AI is now "stupid" again so to speak. My question is: what would a proper place be and how can I accomplish this to create the new instance, new categories and feed them with documents out of my database. Would a singleton be interesting here? |

| EmberJs Data Goes Null to Server Posted: 24 Dec 2016 05:20 AM PST I am building a toy app and wanted to work with a simple 1:many relationship. My car model "hasMany comments" & my comments "belongsTo car".I want a comment to be created from cars/car route.So i didn't created a route for comments/new.For a quick trial i have added a button that has "saveComment" action. <button type="submit" {{action 'saveComment' model}}>Submit</button>
!!! I am passing the model(which refers to current Car object) because in my action i want to read it's id and set it to comments car_id. And here is the correspanding route file model(params){ return this.store.findRecord('car', params.car_id); }, actions: { saveComment(model){ let car = this.store.peekRecord('car', model.id), let newComment = this.store.createRecord('comment'{ car: car, body: 'Some filler text! ', }); car.get('comments').pushObject('newComment'); newComment.save(); }
The problem is, my (let the route be cars/10) current template includes the newly generated comment with the proper body, however when i inspect it, belongsTo relationship looks empty.Since car_id goes null, after a reload, new generated comments disappeares.(not from the database tho, it is saved succesfully without a car relationship).What should i do to get this comments.car saved?

| Rails - render :layout => false on new action Posted: 24 Dec 2016 05:23 AM PST I am using render :layout => false for my new action. All works fine, until I submit the form with validation errors. The create action calls render :new and I see the form, with the bullets outlining the errors. The issue is that the form now renders with application layout and seems to be ignoring the render :layout => false. From what I can tell I believe this is because I am not actually redirecting to :new, just rendering the :new view whilst still in the create action. I cant add render :layout => false to the create action, because rails only allows one render per action. Is there a way to get the form with validation errors to not use the application layout? I still want the bullets with the validation errors. |
| Why is initializing variables so important? Posted: 24 Dec 2016 06:31 AM PST Please can someone explain to me, why NOT initializing first_idx and last_idx causes the code not to run?? When I run it I get this error "undefined local variable or method last_idx". I know that the advice is to always initialize the variables, but I don't understand why. After all first_idx and last_idx will ALWAYS get a value inside the loop because the argument letter is always present in the string (in this particular problem). I'd really appreciate some (simple) insight. Thank you! P.S, I also know that the problem is easily solved using #index and #rindex in Ruby, but I'm not allowed to solve it using straightforward methods. def find_for_letter(string, letter) first_idx = nil 0.upto(string.length - 1) do |idx1| if string[idx1] == letter first_idx = idx1 break end end last_idx = nil (string.length - 1).downto(0) do |idx2| if string[idx2] == letter last_idx = idx2 break end end if last_idx == first_idx return [first_idx] else return [first_idx, last_idx] end end def first_last_indices(word) h = {} word.chars.each do |char| h[char] = find_for_letter(word, char) end h end

| Rails Single Table Inheritance with dynamically defined classes Posted: 24 Dec 2016 03:24 AM PST In using Rails STI (Single Table Inheritance), I have defined a model named Poi (point of interest). Our app's requirement dictate that subclasses of Poi (like Restaurant, Club, etc) must be created in an Admin::Categories view (where it has a class_name string input field), so that an Admin should be able to create a new subclass at anytime without needing a programmer to open a new ruby file with an empty (useless) subclass and re-deploy the app. At the same time, IF in the future we want to specify different behavior (either instance/class methods) for a subclass of Poi, we can just create that ruby file, but that should be an option and not mandatory. The same goes for a different form with different fields for that subclass: we just need to setup a partial_name_for_form instance method in that subclass that returns a string with the partial name and the views will render that accordingly. If none is found, the default Poi views are rendered. Since Rails raises an error if you try to instanciate a new Poi object with 'type' attribute that doesn't match a subclass of Poi (so the subclass MUST be previously defined), we came up with the following solution for dynamically creating the Poi subclasses based on class_name: An after_create hook in model Category that defines the new class immediately using this code: Object.const_set(category.class_name, Class.new(Poi)) A require_dependency call in model Poi file (because it's in the autoload path) to require the ruby files for the subclasses we have eventually created hardcoded subclasses (only if the file exists): Category.all.each do |category|
require_dependency category.class_name.underscore if File.exist (File.join("app","models","pois","#{category.class_name.underscore}.rb"))
end
- An initializer that defines all remaining classes (by 'remaining' I mean other subclasses that don't still have their own ruby file defining them) using the same code in #1, but checking
if Object.const_defined? category.class_name first (because the ones defined by require_dependency don't need to be re-defined). Even tough all this complexity made we almost regret using STI in the first place, it was working fine - in development. But in production environment, after the creation of a new category providing class_name, the Class doesn't get defined, because when trying to create a new Poi with that subclass is raising an error uninitialized constant. I confirmed in Rails console in Production environment that the after_create hook IS working, because the class is being defined there. My wild guess is that because we use Unicorn, this bug could be related to the forking of the application code, but I have no clue how to proceed. |

| prawn bounding box get remaining height Posted: 24 Dec 2016 03:21 AM PST I have been following this stack answer for content overflow, Controlling content flow with Prawn from one column to another, The problem i face is, i cannot get the current position of the cursor inside the bounding box. So that i could do calculation to get the remaining height in bounding box and set it to the next text box, currently it overflows the bounding box. bounding_box([175, starting_y - 240], :width => 30.mm, :height => 67.5.mm) do transparent(1) { stroke_bounds } indent 5,5 do column_box([0, cursor], columns: 1, width: bounds.width) do text "#{cursor}" text "XS", align: :center, inline_format: :true text "XS", align: :center, inline_format: :true text 'XS', align: :center, inline_format: :true text 'aaaa', align: :left text "<b> asda </b>: #{sec_call}", inline_format: true end column_box([0, cursor], columns: 5, width: bounds.width, height: 0.27.cm) do image open('https://image.freepik.com/icones-gratis/t-shirt-no-cabide_318-84568.png'), width: 0.27.cm image open('https://image.freepik.com/icones-gratis/t-shirt-no-cabide_318-84568.png'), width: 0.27.cm end column_box([0, cursor], columns: 1, width: bounds.width) do text "#{care_instr.upcase}" text "#{imported_for}" text "CA 17897" text "FABRIQUE EN CHINE/ HECHO EN" text "CHINA" end # span(bounds.width, position: :left) do # text_box "#{care_instr.upcase}", at: [180, cursor], overflow: :truncate, :width => 25.mm # text_box "#{imported_for}", at: [180, cursor-45], overflow: :truncate, :width => 25.mm # end span(bounds.width, position: :left) do text_to_write = text_box text_to_write, at: [180, cursor], overflow: :truncate, :width => 25.mm, :height => 50.5.mm end end end
text_to_write is a long text which needs to be carried to next column which is working fine, sometimes the "#{sec_call}" value increaes so the text to write overlaps/overflows the table, so i need to dynamically change the height so it flows correctly to next column. Whenever i print cursor inside bounding box it says 0.0, the bounding box height is static and its position also is there any way to calculate the remaining space inside bounding box from current position |

But when I start my server, got this error: /home/zeus/RubymineProjects/rshop/lib/walletone/walletonemiddleware.rb:1:in `<top (required)>': uninitialized constant Walletone (NameError) from /home/zeus/RubymineProjects/rshop/config/application.rb:3:in `require_relative' from /home/zeus/RubymineProjects/rshop/config/application.rb:3:in `<top (required)>' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/railties-5.0.0.1/lib/rails/commands/commands_tasks.rb:88:in `require' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/railties-5.0.0.1/lib/rails/commands/commands_tasks.rb:88:in `block in server' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/railties-5.0.0.1/lib/rails/commands/commands_tasks.rb:85:in `tap' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/railties-5.0.0.1/lib/rails/commands/commands_tasks.rb:85:in `server' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/railties-5.0.0.1/lib/rails/commands/commands_tasks.rb:49:in `run_command!' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/railties-5.0.0.1/lib/rails/commands.rb:18:in `<top (required)>' from /home/zeus/RubymineProjects/rshop/bin/rails:9:in `require' from /home/zeus/RubymineProjects/rshop/bin/rails:9:in `<top (required)>' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/spring-2.0.0/lib/spring/client/rails.rb:28:in `load' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/spring-2.0.0/lib/spring/client/rails.rb:28:in `call' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/spring-2.0.0/lib/spring/client/command.rb:7:in `call' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/spring-2.0.0/lib/spring/client.rb:30:in `run' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/spring-2.0.0/bin/spring:49:in `<top (required)>' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/spring-2.0.0/lib/spring/binstub.rb:31:in `load' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/spring-2.0.0/lib/spring/binstub.rb:31:in `<top (required)>' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:68:in `require' from /home/zeus/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:68:in `require' from /home/zeus/RubymineProjects/rshop/bin/spring:14:in `<top (required)>' from bin/rails:3:in `load' from bin/rails:3:in `<main>'
What I have to include to add Walletone namespace ? |
| belongs_to more than one associated record Posted: 24 Dec 2016 12:21 AM PST Sorry for this nooby question. Reading this here : guides.rugyonrails It says that the belongs_to association is appropriate when each book can be assigned to exactly one author. But what is the best practice if a book can have several authors? I need a table Books and a table Authors, where Books can have 1 to 10 authors. Thanks ! |
| Simple referral system in rails Posted: 24 Dec 2016 06:21 AM PST I'm making a very simple referral system, but the issue I'm seeing is that I need to make two different calls to the DB with a single submit action and I'm not sure how to do that. The general idea for the system is as follows: - A visitor subscribes to the mailing list and receives an email with a referral link with some kind of query string parameter identifying them (e.g. www.domain.com?referrer_id=1)
- When another visitor uses this referral link and signs up, I store a) the new subscriber's email address, and b) the referral information
This would be stored in two tables: subscribers table with | id | email | referrer |referrals table with | id | subscriber_id | referrals |, where referrals is the number of times a subscriber has referred other subscribers Again, I'm wondering how to make two calls -- one for the new subscriber and one for the referral information -- with a single submit action. Or, if that's not the best approach, how to do this using best practices. |
| Whats a good ruby IDE with rails? [on hold] Posted: 23 Dec 2016 11:46 PM PST I am looking to learn ruby on rails. Actually I have to learn it for my internship. So I was looking into some IDEs and so far I learned that cloud 9 is good but it asks me for my credit card info even for the free version. Any good free IDE for ruby and ruby on rails? Or should I just get cloud 9? Thank you for your time. |
| Rails - how to delete duplicate cookies across subdomains? Posted: 23 Dec 2016 10:44 PM PST Since I wanted to start supporting cross subdomain logins on my website. So I changed my session store config from MyApp::Application.config.session_store :cookie_store, key: '_my_app_session'
to MyApp::Application.config.session_store :cookie_store, key: '_my_app_session', domain: '.local.host', # I'm using *.local.host for 127.0.0.1 tld_length: 2
After that, uses got 2 cookies with same name as list below, which caused uses could be logged out. I was using Devise, and it only delete _my_app_session under .local.host. So the user was kept signed in. Name Value Domain _my_app_session abc www.local.host _my_app_session xyz .local.host
How can I delete both of the cookies? |
| How to pass default filter into Filterrific get Posted: 23 Dec 2016 10:14 PM PST I finally got my filterrific get working and its a great gem, if not a little complex for a noob like me. My original index page was filtering the active records based on those nearby to the user like this: def index location_ids = Location.near([session[:latitude], session[:longitude]], 50, order: '').pluck(:id) @vendor_locations = VendorLocation.includes(:location).where(location_id: location_ids) @appointments = Appointment.includes(:vendor). where(vendor_id: @vendor_locations.select(:vendor_id)) end
So this pulls in all of the Appointments with Vendors in the area, but how do I pass this over to the Filterrific search: @filterrific = initialize_filterrific( params[:filterrific], select_options:{ sorted_by: Appointment.options_for_sorted_by, with_service_id: Service.options_for_select }, ) or return @appointments = @filterrific.find.page(params[:page]) respond_to do |format| format.html format.js end
It seems like the Filterrerrific is loading ALL of the appointments by default, but I want to limit to the ones nearby. What am I missing? |
| Parsing XML HTTParty response Posted: 23 Dec 2016 10:06 PM PST I was getting data from an api using HTTParty. I managed to get back the XML response, and it looks like HTTParty has made that xml response into Ruby. How can I navigate through the hashes and get the data I need? For instance, say I wanted the "Name", which is "29TH AVENUE STN/ARBUTUS". The API key works fine, since I am getting a response back. Just not too sure how I can navigate through and get the data I want, and to put it into my view. index.html.erb: <% @courses.each do |course| %> <%= course %> <% end %>
HTTparty response: ["Route", { "RouteNo" => "016", "Name" => "29TH AVENUE STN/ARBUTUS ", "OperatingCompany" => "CMBC", "Patterns" => { "Pattern" => [{ "PatternNo" => "E5TP", "Destination" => "29TH AVE STN", "RouteMap" => { "Href" => "http://nb.translink.ca/geodata/trip/016-E5TP.kmz" }, "Direction" => "EAST" }, { "PatternNo" => "EB1", "Destination" => "29TH AVE STN", "RouteMap" => { "Href" => "http://nb.translink.ca/geodata/trip/016-EB1.kmz" }, "Direction" => "EAST" }, { "PatternNo" => "EB5", "Destination" => "29TH AVE STN", "RouteMap" => { "Href" => "http://nb.translink.ca/geodata/trip/016-EB5.kmz" }, "Direction" => "EAST" }] } }]
Model for getting the response class Checker include HTTParty base_uri 'http://api.translink.ca/rttiapi/v1/routes' default_params apikey: "[my proper api key]" format :xml def self.for term get("", query: {stopNo: term})["Routes"]["Route"]["RouteNo"] end end
Controller for the Model class TimesController < ApplicationController def index @search_term = '51048' @courses = Checker.for(@search_term) end end
