| no implicit conversion of Symbol into Integer - working with param from URL Posted: 09 Jul 2016 07:12 AM PDT Trying to convert a param included in the the URL into an integer, to operate with it within a Controller - The format of the URL is like http://localhost:3000/charges?data=149&email=email@gmail.com The charges_controller.rb looks like: class ChargesController < ApplicationController protect_from_forgery with: :null_session def new end def create @amount = {} @amount = params [:**data**][:email].map(&:to_i) @amount.save customer = Stripe::Customer.create( :email => params[:stripeEmail], :source => params[:stripeToken] ) charge = Stripe::Charge.create( :customer => customer.id, :amount => @amount, :description => 'Rails Stripe customer', :currency => 'eur' ) rescue Stripe::CardError => e flash[:error] = e.message redirect_to new_charge_path end end
And the params I can see in better_errors screen detect already the 'data' amount: {"stripeToken"=>"asdfasdf", "stripeTokenType"=>"card", "stripeEmail"=>"email@gmail.com", **"data"=>"149"**, "email"=>"email@gmail.com", "action"=>"create", "controller"=>"charges"}
In the live shell in better errors if I do params[:data].to_i it returns 149, but if I include it directly in the controller like: @amount = {} @amount = params [:data].to_i[:email] @amount.save
it returns undefined method `to_i' for [:data]:Array Tried also mapping them like: @amount = params [:data][:email].map(&:to_i),same result "no implicit conversion of Symbol into Integer" |
| SocketError at /sidekiq/ getaddrinfo: nodename nor servname provided, or not known Posted: 09 Jul 2016 07:01 AM PDT I'm a novice Rails dev building an app connected to redis + sidekiq. I must have some configuration error, but I'm not sure what exactly it is. Below, I'll write about what exactly confuses me here: Upon running rails s, I get the following error: 2016-07-09 08:55:46 - SocketError - getaddrinfo: nodename nor servname provided, or not known: /Users/rohitrekhi/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/redis-3.3.0/lib/redis/connection/ruby.rb:177:in `getaddrinfo' /Users/rohitrekhi/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/redis-3.3.0/lib/redis/connection/ruby.rb:177:in `connect' /Users/rohitrekhi/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/redis-3.3.0/lib/redis/connection/ruby.rb:260:in `connect' /Users/rohitrekhi/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/redis-3.3.0/lib/redis/client.rb:336:in `establish_connection'
So I figured it must be a redis connection error. When I ping redis to see if connection goes through, it shows the following: $ redis-cli ping => PONG
So if the redis connection goes through, maybe it's a Sidekiq issue? I implemented the Sidekiq web interface via Sinatra, and got the following error when I tried to view it: SocketError at /sidekiq/ getaddrinfo: nodename nor servname provided, or not known
So now I'm guessing the error is actually via Sidekiq, but I'm not sure where I dropped the ball via configurations on the host/server/sockets. Any ideas what exactly is causing this and if it's an error with Sidekiq or redis? This is my initializer file for sidekiq in config/initializers/sidekiq.rb: Sidekiq.configure_server do |config| config.redis = { url: 'redis://redis.example.com:6379/12', network_timeout: 5 } end Sidekiq.configure_client do |config| config.redis = { url: 'redis://redis.example.com:6379/12', network_timeout: 5 } end
And this is my config/initializer/redis.rb: $redis = Redis.new(:host => 'localhost', :port => 6379)
I've also opened three terminal windows turning on the redis server, sidekiq, and my rails server. Thanks in advance! |
| ActiveRecord feature proposal: find_unique_by Posted: 09 Jul 2016 06:51 AM PDT I have sent the following message to the Rails Core mailing list and got no reply. I assume there was no interest in this feature and/or there is something wrong with the following code. If you can provide any feedback, I'd appreciate it very much. I'm not asking a specific question, I'm asking for your opinion on the following feature proposal and the suggested implementation. -- I used MongoDB before PostreSQL with an ODM called MongoEngine, which has a method for retrieving single results from the DB. It is similar to ActiveRecord find_by! as it raises an exception if no matching records are found. The difference is, it also raises an exception if more than one record matched the query. I've been looking for a similar feature in ActiveRecord but haven't found any so far. I'm currently using the following workaround, which works with chained where methods, def ensure_unique # Ensures an Active Record query returns a *single* record, or raise exception # Usage: MyModel.where(foo: 'bar').where(baz: 'qux).ensure_unique if self.many? raise ActiveRecord::RecordNotUnique, 'More than one record matched criteria. A single match was expected.' elsif self.empty? raise ActiveRecord::RecordNotFound, 'No matching records were found. A single match was expected.' else # The where method always returns a collection, even when only one record is found. # We want to return a single item. return self.first end end
It could also be implemented as a query method (such as find_by!). However, I'd have to look further into it and find a way to support queries involving "AND" logic, such as chaining multiple where methods. def find_unique_by!(*args) # Ensures an Active Record query returns a *single* record, or raise exception # Usage: MyModel.find_unique_by(foo: 'bar') result = where(*args) if result.many? raise ActiveRecord::RecordNotUnique, 'More than one record matched criteria. A single match was expected.' elsif result.empty? raise ActiveRecord::RecordNotFound, 'No matching records were found. A single match was expected.' else return result.first end end
One use case would be scenarios where you don't have control over the data being inserted in the database (you are working with a legacy DB or a DB managed outside your organization), so you are unable to ensure records are unique. Any feedback will be greatly appreciated. |
| Rails - Update Counter Variable when a user shows up as a search result Posted: 09 Jul 2016 06:33 AM PDT When searching for students and showing results, I want to be able to update a field in the student_metric table to show how many times a student has shown up in search results. However, every time i run the show routine i get a undefined method `id' for nil:NilClass. Why wont it find the link between the search_student and student_metric table? searches controller def show @search = current_user.searches.find_by(id: params[:id]) @search.search_students.each do |c| c.student_metric.searchinclusions += 1 end end
search model class Search < ActiveRecord::Base belongs_to :user def search_students students = StudentProfile.all students = students.where(["name LIKE ?", "%#{name}%"]) if name.present? return students end end

| How does one use the new "rails new myapp --api" with a client-side JavaScript framework? Posted: 09 Jul 2016 06:25 AM PDT I apologize if this is a stupid question, but I don't understand the fundamentals of using JSON in accordance with a JavaScript framework in Rails 5.0: Rails is not only a great choice when you want to build a full-stack application that uses server-side rendering of HTML templates, but also a great companion for the new crop of client-side JavaScript or native applications that just needs the backend to speak JSON. We've made this even clearer now with the new –api mode. If you create a new Rails application using rails new backend --api, you'll get a slimmed down skeleton and configuration that assumes you'll be working with JSON, not HTML. React seems to be favored by many, so I want to learn how to use it with a Rails backend. To build the hashes I'm leaning toward using Jbuilder. My main confusion is how to build a layout without an .html.erb view. If I only have two files, one .json.jbuilder, one .js.jsx — how do I call the React components? Or does every controller method need three corresponding views? Or am I just missing the point of --api entirely? |

What i realized is that My os causes that (Darwin aka. Mac OSX is the valid os) Is my guess right? If yes, is there any way to install the platform on Ubuntu? If not, how can i correct this error? Thank you in advance! |

| Flexible CMS for custom Web-Project Posted: 09 Jul 2016 02:53 AM PDT I am starting new project, and I am hesitating between choosing correct CMS and underlying technology. I will use item as an abstract term, it is something like an order. My project is not standard blog or e-commerce site. It will have custom features like map of items, live tracking of items, notification about new item. - Live tracking of items on the map
- List of items with autoupdate when new item is added
- User personal account with the history of items, list current items.
- Feedback system
- User roles
- Items priorities
It would be easy to create using only framework, but in my case I need to have admin panel to control items, and of course security should be taken into consideration. Because reinventing the wheel will lead to security issues. I have used some CMS but they seem unsuitable for my goals. And what about language, I used PHP in a lot of projects, once used Ruby On Rails, Ruby is greatly structured language, but as far as I know it has performance issue comparing with PHP Please suggest the right technology or at least share you experience of using flexible CMS. |

| How to code a unit conversion Posted: 09 Jul 2016 02:11 AM PDT I have a scenario where a user can enter a quantity, a "from unit" and a "to unit" and I wish the app to display the quantity converted. I am using RoR and Postgres. For example: if the user entered 1000 grams to kilograms the app would return 1 kg if the user entered 12 eggs to dozen the app would return 1 dozen if the user entered 250 millilitres to litres the app would return .25 litres I had thought of using two simple tables being: Units: ====== Unit_id | Unit_name 1 | Grams 2 | Kilograms 3 | Eggs 4 | Dozen 5 | Millilitres 6 | Litres 7 | Millimetres 8 | Centimetres 9 | Meters Conversions: ============ Conversion_id | From_unit_id | To_unit_id | Multiplier 1 | 1 | 2 | 1000 2 | 3 | 4 | 12 3 | 5 | 6 | 1000 4 | 7 | 8 | 10 5 | 8 | 9 | 100
Whilst this works it has a couple of flaws that I have been unable to resolve: 1) The conversion only works one way. Meaning that without repeating the logic I can convert from Grams to Kilograms but not Kilograms to Grams. 2) The conversion is single step only. Meaning I can convert from millimetres to centimetres and centimetres to metres but I cannot convert from millimetres to metres. Point (1) above can be resolved by duplicating every conversion with the inverse logic and point (2) can be resolved by including every conversion combination however this doesn't feel right. Is there a better way of approaching this problem? |

| Issue regarding ajax search rails Posted: 08 Jul 2016 10:58 PM PDT I tried to built my search with Ajax and I have added remote: true , and respond_ to block in the controller and I created the partial _xvaziri.html.erb and finally index.js.erb. But I am not getting the desired results for the Ajax search. Please refer the images as shown below; 
In the above image when I searched for "cash" then I get rendering multiple times in the terminal.

| rails assets precompile error with a js with variable definitions with a -. works on one computer and in other not Posted: 09 Jul 2016 04:17 AM PDT I'm running RAILS_ENV=production bundle exec rake assets:precompile and getting this error ...somefile.js ExecJS::ProgramError: Unexpected token: operator (-) (line: 3, col: 9, pos: 11)

I guess the problem is because the variable name includes a -. However using the same ruby version on local computer with same command, it's able to process correctly without the error: On my local computer: RAILS_ENV=production bundle exec rake assets:precompile`
And it was able to process the offending file without problems, and generated this file: public/assets/js/some=file-68c9a5f2e1f2216c5d3d2b9fcd7741155113425f7f46f18187ad5b98e1a11092.js $ ruby -v ruby 2.2.1p85 $ gem list | grep js execjs (2.5.2)

the controller action I have set up is: def shipment if request.headers['Content-Type'] == 'application/json' data = JSON.parse(request.body.read) x = JSON.parse(request.body.read)["fulfillment"]["order_number"] y = JSON.parse(request.body.read)["fulfillment"]["tracking_number"] puts x puts y render nothing: true else # application/x-www-form-urlencodedw data = params.as_json x = JSON.parse(request.body.read)["fulfillment"]["order_number"] y = JSON.parse(request.body.read)["fulfillment"]["tracking_number"] puts x puts y render nothing: true end end
this throws an error: JSON::ParserError: A JSON text must at least contain two octets! But if I remove one of the x or y variables from each conditional it parses the correct value i am looking for ( the tracking number or order number). So as long as I only parse 1 value it works. I don't understand why. Here is the link to the ship hero apiary for the Webhook Shipment URL documentation. Any help would be greatly appreciated. |
| Gemfile is not using the specified ruby version Posted: 08 Jul 2016 09:41 PM PDT I'm making a project and when I run a generate command I get the following error: fullpath: /Users/adamgoldberg/shopify-sinatra-app/theappearsystemcontrol6 Your Ruby version is 2.3.1, but your Gemfile specified 2.2.2 Bundler::RubyVersionMismatch: Your Ruby version is 2.3.1, but your Gemfile specified 2.2.2 /Users/adamgoldberg/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/bundler-1.12.5/lib/bundler/definition.rb:417:in `validate_ruby!' /Users/adamgoldberg/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/bundler-1.12.5/lib/bundler.rb:91:in `setup' /Users/adamgoldberg/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/bundler-1.12.5/lib/bundler/setup.rb:19:in `<top (required)>' /Users/adamgoldberg/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' /Users/adamgoldberg/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'bundler: failed to load command: rake (/Users/adamgoldberg/.rbenv/versions/2.3.1/bin/rake)
I have to use ruby version 2.3.1 for my project so I have attempted changing my Gemfile version. my gemfile now contains this: ruby "~> 2.3"
I have tried all sorts of commands so that the Gemfile recognises that I want to use a different ruby version. I have tried: bundle update bundle install gem bundle install rbenv rehash
even my Gemfile.lock says it is using 2.3.1: RUBY VERSION ruby 2.3.1p112
I have even deleted the project and started again. Please help
An update: I deleted the project and restarted. here are the exact steps I took from my home directory ruby -v: #2.3.1 git clone https://github.com/kevinhughes27/shopify-sinatra-app.git gem install shopify-sinatra-app shopify-sinatra-app-generator new myshop
and the same error as above appeared: Your Ruby version is 2.3.1, but your Gemfile specified 2.2.2
My Gemfile looks like this: source 'https://rubygems.org' gemspec
it's practically empty... I haven't even specified the ruby version I then ran bundle install bundle update
still the same error appears. I then specified in my Gemspect the ruby version and it now looks like this: source 'https://rubygems.org' ruby "2.3.1" gemspec
but still the same error appears |

| Rails User has_many completions through lessons: Boolean Controller and Routes Posted: 08 Jul 2016 06:28 PM PDT Ok, I'm a novice rails developer and I've been thinking about this project all day and I'm not exactly sure how to do it and was looking for some clarification on the Controller, Routes and button logic portion of this project. I understand the model layout. I think. The basic functional description goes as follows:
User views a video lesson and then clicks a button to mark the lesson as completed after viewing the video and then is redirected to the next video lesson (assuming they're in order by lesson_id). Button colors changes to indicate the lesson has been viewed and the Completions table gets updated to indicated that the lesson has been completed (boolean). Here's the overview of my models: User has_many :completions has_many :completed_steps, through: :completions, source: :lesson Lesson has_many :completions has_many :completed_by, through: :completions, source: :user Completions belongs_to :user belongs_to :lesson
My Completions Table looks like this: t.integer "user_id" t.integer "lesson_id" t.boolean "completed_step" t.string "completed_by"
So I'm guessing I need to add a Completions Controller and implement a method whereby the completed_step boolean gets updated as well as the appropriate user_id, lesson_id and maybe the completed_by as well (although I view that one as optional) get updated?? Here's what I don't know and it doesn't seem terribly straightforward. The controller logic... CompletionsController or LessonsController?? def complete_lesson what goes in here? end
And then the routes.rb logic?? match '/completions/complete_lesson' => 'completions#complete_lesson', as: 'lesson_complete'
Then the button will look something like this then I guess?? <% if current_user.completed_steps.include? @lesson %> <% if @lesson.next %> <%= button_to "Completed", lesson_path(@lesson.next), class: "btn btn-success btn-lg" %> <% end %> <% else %> <%= button_to "Mark this Lesson as Complete", lesson_complete_path(@lesson), method: :put, class: "btn btn-warning btn-lg" %> <% end %>

| how to get key in ruby on rails .each loop Posted: 08 Jul 2016 06:38 PM PDT In laravel I am use to being able to access the key in a loop. In rails I cannot find answer to how to get that from the loop. Standard loop like so <% @subjects.each do |subject| %> <div class="col-md-6 subjectColumn"> <div class="subjectBox subjectBox-<%= key %>"> <h2><%= subject.title.capitalize %><h2> <p><%= subject.description %></p> <a href="/subjects/<%= subject.id %>">View courses<i class="fa fa-angle-right"></i></a></h2> </div> </div> <% end %>
I want to add the integer for the key in the code above. I have tried... <% @subjects.keys.each do |key, subject|
...and other various things I found here and elsewhere but nothing worked. The above code created an error. Most of the things I found just did not give any number. Any help with this would be greatly appreciated. I feel I probably just have not got the syntax quite correct or something. |
| Call controller action when user clicks on a table cell Posted: 08 Jul 2016 05:01 PM PDT I have a table in my view. How do I call a controller action ("update") when the listener clicks on table cell. I also need to send arguments to the controller. Does this need AJAX? |
| wrong username/ password error-handling using httparty Posted: 08 Jul 2016 08:32 PM PDT I am creating a local gem utilizing httparty to connect to specific website to get auth token. I was able to get the program to fetch auth_token when I entered the correct email and password. However, if I put the wrong email/password, it returns: NameError: uninitialized constant Gemname::InvalidStudentCodeError require 'httparty' class Gemname include HTTParty def initialize(email, password) response = self.class.post("https://www.website.io/api/v1/sessions", body: {"email": email, "password": password}) #####error-handler##### if StandardError puts "invalid email/pass" end ####################### @auth_token = response["auth_token"] end end
It seems like most errors are categorized under standard error. The idea is to run from irb Gemname.new('email', 'wrong-password'), it would return "Wrong email/password". How should I handle the error to display the proper message? Edit: I tried these codes on initialize: if StandardError "error" end
I also tried created on lib folder, a folder named gemname -> error.rb error.rb: class InvalidStudentCodeError < StandardError def initialize(msg="invalid email or password") super(msg) end end
and on initialize: raise InvalidStudentCodeError.new() if response.code == 401

| fields_for doesn't save object sin rails Posted: 09 Jul 2016 04:16 AM PDT Im interested why does my nested form in RoR doesnt save child objects :( For now, it just save the Parent (Printer) value and makes the child(Color) disappear on second render (error)! What Am I doing wrong? Parent model class Printer < ActiveRecord::Base belongs_to :user validates :user_id, presence: true validates :model, presence: true has_many :colors, dependent: :destroy accepts_nested_attributes_for :colors end
Child model class Color < ActiveRecord::Base belongs_to :printer validates :color, presence: true end
View (new.html.erb) <%= form_for @printer do |p|%> <%= p.text_field :model %> <%= p.fields_for :colors do |color|%> <%= color.text_field :color%> <% end %> <%= p.submit "Add"%> <% end %>
And controller def create @printer = current_user.printers.build(printer_params) if @printer.save redirect_to @current_user else render 'new' end end def new @printer = Printer.new @printer.colors.build end private def printer_params params.require(:printer).permit(:model) end
Edit: This one helps private def printer_params params.require(:printer).permit(:model, colors_attributes: [:color]) end
