| How to create a Javascript stubbed object during Rspec feature specs? Posted: 08 Jul 2016 08:42 AM PDT I have some current feature specs in rspec that currently test some javascript functionality. In those libraries, I am using Modernizr to detect primarily just touchevents. Since I am using Poltergeist and PhantomJS, Modernizr.touchevents always returns true even though I would prefer for it to return false to run other conditionals. Is there a way to explicitly stub out Modernizr.touchevents or just Modernizr all together? I have tried the following: Modernizr.touchevents = falseModernizr.touchevents = {}Modernizr = {}- Do not include the modernizr library during tests, however my tests fail because I am expecting Modernizr to be there.
Even if its not Modernizr, how do you stub out javascript libraries especially if you don't care about its functionality at the moment of testing. Thanks |
| How to change href in HAML if statement Posted: 08 Jul 2016 08:53 AM PDT I have 2 different paths that my workList holds, and they both path to the same place. I want them to path differently. Here's my code: %table.table-base.table-striped.table-hover{:id => "work-list-table"} %tbody - @work_list.each do |workList| //there are two items in this object %tr{:id => workList.id,href: duplicate_claims_work_lists_path, :style => "cursor:pointer", :onclick=>"workListTrActions(this)"} -if workList.work_list_name == "Provider Payments" //href = provider_payments_work_lists_path %td %ul.custom-ul %li %h4 =workList.work_list_name
As you can see, the two items I have both path to duplicate_claims_work_lists_path. I want to change the href to path to provider_payments_work_lists_path. Can I change it in the if statement? |

| HAML code - need help in changing particular column to editable column ; Ruby on Rails Posted: 08 Jul 2016 08:29 AM PDT I want to make the particular 'HC' column to editable column. so that if i make changes in the existing data, the new data should get saved directly into my database. ( Just like double click the particular data the it should goes to editable mode and when i click outside it gets saved or making the entire 'HC' column to editable column and having a common button to save the data.) Can anyone please help me on this. Below is my Haml code. %thead %tr %th= sortable_column t("formtastic.labels.organization.city_town"), :column => "City/town" - if view_zone %th= sortable_column t("formtastic.labels.organization.Zone"), :column => "Zone" %th.number= sortable_column t("formtastic.labels.organization.HC"), :column => "HC", :direction => :desc %th.number= sortable_column t("formtastic.labels.organization.%_of_HC"), :column => "%_of_HC", :direction => :desc %th.number= sortable_column t("formtastic.labels.organization.Overall_%"), :column => "Overall_%", :direction => :desc - if current_user.admin? %th

| Is there a Gem to preprocess ruby code and find errors that would occur runtime? Posted: 08 Jul 2016 08:49 AM PDT We have huge code base and we are generating issues that would have been caught at compile time in type languages such as Java but we are not catching them until runtime in Ruby. This is bad since we generate bugs that most of the time are typos or refactoring that leaves some invalid code. Example: def mysuperfunc # some code goes here # this was a valid call but not anymore since enforcesecurity # signature changed @system.enforcesecurity end
I mean, IDEs can do it but some guys use ATOM or sublime, so we need something to "compile" and report that kind of issues so they don't reach deployment. What have you been using? This is generating a little percentage of our bug reports, but since we are forced to produce at a ridiculous pace we don't have 100% code coverage. If there is no tool to help, I'll just make sure everybody uses and IDE and run the reports with tools such as Rubymine. Our stack includes, rspec, minitest, SimpleCov. We enforce code reviews, multistack deployments (dev, qa, pre-prod, sandbox, prod). And still some issues are reaching higher level and makes us programmers look bad. I'm not looking of magic, just a little automation that might help a bit. |

| Unequally interleave two ruby arrays Posted: 08 Jul 2016 08:40 AM PDT I'd like to interleave two arrays without exactly alternating them. For example, given: a = [1,2,3,4,5,6,7,8,9] b = ['a','b','c']
I'd like to receive f = [1,2,'a',3,4,'b',5,6,'c',7,8,9] as the output. I want one element from b for every two elements in a. A solution appears to be: a = [1,2,3,4,5,6,7,8,9] b = ['a','b','c'] even, odd = a.partition.each_with_index{ |_, i| i.even? } res = even.zip(odd,b) res = res.flatten.reject(&:blank?) #=> [1, 2, "a", 3, 4, "b", 5, 6, "c", 7, 8, 9]

| Redcarpet Custom Markdown Parser class. How to render partial in Helper class as a response Posted: 08 Jul 2016 06:47 AM PDT I created a custom markdown parser class for Redcarpet because there is some custom syntax I want to parse on my blog. I want the image parser to return a whole HTML structure. It would be tedious to maintain this html (say 20 lines of divs with classes and static text) inside a Ruby string, which is why I tried to extract this into a partial. The image method below parses the markdown syntax and then passes the title, image link and html classes to the partial. My question is how I can make this work. I've tried render which doesn't render to the response body and render_to_string which doesn't work either as the returned string seems to be nil. If there is another way to extract HTML/ERB code from my ruby code then let me know. I really don't want to hack HTML code inside a string variable. CustomerMarkdownParser class inside application_helper.rb class CustomMarkdownParser < Redcarpet::Render::HTML include ActionView::Helpers::UrlHelper include ActionView::Helpers::AssetTagHelper include AbstractController::Rendering def parse_media_link(link) # parsing code end #  #  #  #  def image(link, title, alt_text) size = nil klass = nil if nil != (parse = parse_media_link(link)) puts parse image = Image.find_by_id(parse[:id]) || Image.find_by_slug(parse[:id]) caption_text = "" link = "" if image klass = parse[:class] if klass.match(/right|left/) # use smaller image version for left/right floating images link = image.file_url(:small) else link = image.file_url(:post) end caption_text = parse[:alt_text] image.caption ||= parse[:alt_text] image.save end end # I have a partial called post_image that contains #the image HTML code I want this method to return. render_to_string 'application/post_image', locals: {url: link, caption: caption_text, class: klass} end
EDIT 1: I have heard of the render_anywhere gem, but it seems really dodgy to add a whole gem just to achieve this simple task. |

| NameError in Devise::SessionsController#create undefined local variable or method `controller_path' for #<Devise::SessionsController Posted: 08 Jul 2016 06:47 AM PDT I'm working on a rails app that had basic user auth functionality via devise gem. Sign in was working fine, but I realized now that I sign up it throws me the following error: ActionController::UrlGenerationError in Devise::SessionsController#create No route matches {:action=>"show", :controller=>"controllers"} missing required keys: [:id]
I didn't create a controller named Controllers, and the error refers to Devise, so I figured something is wrong with the way I'm passing user details into the Devise controller/ with the way I'm handling routes. So I looked into my config/routes.rb and I saw the following line: resources :controllers
I have no recollection of adding this line. It's possible that I was debugging something a while ago and threw this line in there but from what I saw in the devise wiki nothing like this should have been auto-generated. So when I deleted that line, signing in then threw the following error: NameError in Devise::SessionsController#create undefined local variable or method `controller_path' for #<Devise::SessionsController:0x007fe6b6cd6730> Did you mean? controller_name
Here is my Controller controller: class ControllersController < ApplicationController before_action :set_controller, only: [:show, :edit, :update, :destroy] # GET /controllers # GET /controllers.json def index @controllers = Controller.all end # GET /controllers/1 # GET /controllers/1.json def show end # GET /controllers/new def new @controller = Controller.new end # GET /controllers/1/edit def edit end # POST /controllers # POST /controllers.json def create @controller = Controller.new(controller_params) respond_to do |format| if @controller.save format.html { redirect_to @controller, notice: 'Controller was successfully created.' } format.json { render :show, status: :created, location: @controller } else format.html { render :new } format.json { render json: @controller.errors, status: :unprocessable_entity } end end end # PATCH/PUT /controllers/1 # PATCH/PUT /controllers/1.json def update respond_to do |format| if @controller.update(controller_params) format.html { redirect_to @controller, notice: 'Controller was successfully updated.' } format.json { render :show, status: :ok, location: @controller } else format.html { render :edit } format.json { render json: @controller.errors, status: :unprocessable_entity } end end end # DELETE /controllers/1 # DELETE /controllers/1.json def destroy @controller.destroy respond_to do |format| format.html { redirect_to controllers_url, notice: 'Controller was successfully destroyed.' } format.json { head :no_content } end end private # Use callbacks to share common setup or constraints between actions. def set_controller @controller = Controller.find(params[:id]) end end
I haven't overridden Devise's Controller method at all, but it seems that Devise requires resources :controller? I'm not sure I fully understand the problem here. But does anyone know what I can do to fix this? |
| Practical usage of Hadoop in project Posted: 08 Jul 2016 06:23 AM PDT I'm going to use Hadoop in my new project. The project concept is like on the following image:  User has device which produces some data (logs). User can get data from device as a file and upload it to web app/hadoop. I'm going to build web app using Ruby on Rails. I know some basics of Hadoop (HDFS, Mappers, Reducers), but I don't know how to use Hadoop in practical way. The project is now only a concept, because I would like to get some tips first and then adjust project's components to collected tips. My major considerations are about: - Web app should be stored on the same location as Hadoop? (the same server/cloud/service provider)
- How to upload files? Can be in the web app form to upload files? Or is it better to create desktop application to upload file (possible file size: 100MB - 1GB)?
- If it would be desktop application, it's better to send data directly to Hadoop or somehow through web application?
- Can you point me some useful framework/tool/API/resources for uploading from external resources (my web app or desktop application)?
- How to use in right way the Hadoop data? Let's assume that user's file comes to Hadoop. I know that I can run Mappers and Reducers on this file what produces output file (or puts some data to HBase - I'm right?). To get this data I need proper output file or get some "SELECT" from HBase, am I right? Does Hadoop contain any trigger to send info to external web app when job is done?
I appreciate every hint in this topic. |
| Cloning a gem to a local file isn't detecting my changes Posted: 08 Jul 2016 06:46 AM PDT I need to make changed to the Twitter gem, so I cloned it to a local folder, then changed my bundle file like so: gem 'twitter', :path => '~/code/twitter-ruby'
I added a new method, and ran a test that simply calls the method, to start off with. But I get an error of undefined method. In other words, it hasn't detected my changes. I tried commenting out a whole file, ran my other tests and those all worked, as though the file were still there. In my project I'm still importing as require 'twitter'. I've tried running bundle update twitter, I've tried removing it from the bundle, I've tried increasing the version number (which it does detect, and updates to the most recent version), I've tried committing my changes to GIT.

| before_action with "or" statement Posted: 08 Jul 2016 07:13 AM PDT I have several different user types within my application. I was trying to do something like this when accessing a controller; class Admins::ProgrammesController < ApplicationController # only allow entry if the user is one of these types. before_action :authenticate_admin! || :authenticate_super_admin! || :authenticate_programme_leader! || :authenticate_caseworker! def index end
To check the users type is allowed to access this controller. Alas, that does not seem to be right. Rails only pays attention to the first before_action argument - checks if the user is admin. So my spec does not pass if user is caseworker for example. How can I achieve this in a similar way? UPDATE As requested, more code.. This is my failing spec; RSpec.describe Admins::ProgrammesController, :type => :controller do context 'authenticated user' do before :each do @user = FactoryGirl.create :caseworker sign_in @user end describe 'GET index' do it 'responds with a 200 OK status code' do get :index expect(response).to have_http_status(:success) end end end end
I am 100% confident that the Casework type user is being created. Here is the factory; FactoryGirl.define do factory :caseworker, class: 'Users::Caseworker' do email { "me@example.com" } password { "password" } end end
Here is the relevant lines from the routes file; Rails.application.routes.draw do devise_for :users, controllers: {sessions: 'users/sessions'}, skip: :registrations devise_for :admins, class_name: 'Users::Admin' devise_for :caseworker, class_name: 'Users::Caseworker' devise_for :cardholder, class_name: 'Users::Cardholder' devise_for :programme_leader, class_name: 'Users::ProgrammeLeader' devise_for :super_admin, class_name: 'Users::SuperAdmin' scope module: 'admins' do # this is the route in question... resources :programmes, only: [:index, :show, :new]

But what is the most performant way to write a test for this? subject(:ability){ Ability.new(current_user) } let(:current_user){ nil } let(:other_user){ nil } owned_house = House.create(user_id: current_user.id) other_house = House.create(user_id: other_user.id) is_expected.to have_abilities( :manage, Address.new(house_id: owned_house.id) ) is_expected.to not_have_abilities( :manage, Address.new(house_id: other_house.id) )
Is there a better way to do this that does not require House to be written to the database? |
