| How can I return the highest "valued" element -- per "name" -- in an Array? Posted: 30 Jun 2016 07:27 AM PDT I've read a lot of posts about finding the highest-valued objects in arrays using max and max_by, but my situation is another level deeper, and I can't find any references on how to do it. I have an experimental Rails app in which I am attempting to convert a legacy .NET/SQL application. The (simplified) model looks like Overlay -> Calibration <- Parameter. In a single data set, I will have, say, 20K Calibrations, but about 3,000-4,000 of these are versioned duplicates by Parameter name, and I need only the highest-versioned Parameter by each name. Further complicating matters is that the version lives on the Overlay. (I know this seems crazy, but this models our reality.) In pure SQL, we add the following to a query to create a virtual table: n = ROW_NUMBER() OVER (PARTITION BY Parameters.Designation ORDER BY Overlays.Version DESC)
And then select the entries where n = 1. I can order the array like this: ordered_calibrations = mainline_calibrations.sort do |e, f| [f.parameter.Designation, f.overlay.Version] <=> [e.parameter.Designation, e.overlay.Version] || 1 end
I get this kind of result: C_SCR_trc_NH3SensCln_SCRT1_Thd 160 C_SCR_trc_NH3SensCln_SCRT1_Thd 87 C_SCR_trc_NH3Sen_DewPtHiThd_Tbl 310 C_SCR_trc_NH3Sen_DewPtHiThd_Tbl 160 C_SCR_trc_NH3Sen_DewPtHiThd_Tbl 87
So I'm wondering if there is a way, using Ruby's Enumerable built-in methods, to loop over the sorted array, and only return the highest-versioned elements per name. HUGE bonus points if I could feed an integer to this method's block, and only return the highest-versioned elements UP TO that version number ("160" would return just the second and fourth entries, above). The alternative to this is that I could somehow implement the ROW_NUMBER() OVER in ActiveRecord, but that seems much more difficult to try. And, of course, I could write code to deal with this, but I'm quite certain it would be orders of magnitude slower than figuring out the right Enumerable function, if it exists. (Also, to be clear, it's trivial to do .find_by_sql() and create the same result set as in the legacy application -- it's even fast -- but I'm trying to drag all the related objects along for the ride, which you really can't do with that method.) |

| Why Capybara feature tests don't wait? Posted: 30 Jun 2016 07:35 AM PDT I have a small trouble with my tests suite: when I run spec which the checking ajax action on the page, sometimes I get random error Failure/Error: expect(page).to have_content 'DHH'
This error shows very rarely (about 1/100), but this very confused me. I decided this a 'race condition' cause, and I add this config in my spec/rails_helper.rb Capybara.default_max_wait_time = 10
but this is don't help for me, and I decided add timestamps it 'adds new DHH', js: true do find('#modal_new_dhh').click fill_in('name', with: 'DHH') p 'click button' p Time.now.strftime('%H:%M:%S.%L') click_button('Submit') p 'checking content' p Time.now.strftime('%H:%M:%S.%L') expect(page).to have_content 'DHH' p 'after checking content' p Time.now.strftime('%H:%M:%S.%L') end
and see that "click button" "17:34:43.083" "before checking content" "17:34:43.127" "after checking content" "17:34:43.213"
why Capybara don't wait after click button? sorry for my bad English |
| How do I generate a temporary page like confirmation page in rails? Posted: 30 Jun 2016 06:41 AM PDT I am using devise and want to redirect users to a confirmation page upon signup, this is what I am doing right now: users/registrations_controller.html.erb class Users::RegistrationsController < Devise::RegistrationsController def confirm_email end private def after_inactive_sign_up_path_for(resource) users_confirmyouremail_path end end
config/routes.rb devise_scope :user do get 'users/confirmyouremail' => 'users/registrations#confirm_email' end
I have no problem with redirecting the page after signup. However, I think it is quite weird that anyone can visit the page with url like `host.com/confirmyouremail' and see the confirmation page. Are there any ways I can write a route that will use random code that is allow only for one time visit? Thanks in advance. |

| Validate model without associated models Posted: 30 Jun 2016 07:13 AM PDT I have a model user that has_one business At certain times I want to validate user on its own without taking into account business. At the moment if user.business.valid? is false
this will make user.valid? also false even if the user record on its own is valid. If in user.rb I do has_one :business, :validate => false it will not take business into account when validating user, but it will then always do it, which is what I dont want. What is the syntax to call the validation on user without taking the business association into account? If I do user.business(validate: false).valid? it will ignore the validation on business and user. The above will be true even if user is invalid. Any ideas? Update: Validations: user.rb
validates :first_name, presence: true
business.rb
validates :name, presence: true

| Rails/SQL: find statistics about a belongs_to relation Posted: 30 Jun 2016 06:13 AM PDT I have the following models class Project has_many :contributions end class Contributor has_many :contributions end class Contribution belongs_to :contributor belongs_to :project end
I'm trying to find how many contributors contributed in how many projects and sort by number of projects contributed to. Example: - Person 1 made contribution to Project 1 - Person 1 made contribution to Project 2 - Person 2 made contribution to Project 1 - Person 2 made contribution to Project 3 - Person 2 made contribution to Project 4 - Person 3 made contribution to Project 4 - Person 3 made contribution to Project 5
In this case - Person 1 made 2 contributions in 2 seperate projects. - Person 2 made 3 contributions in 3 seperate projects. - Person 3 made 2 contributions in 2 seperate projects.
which means - 2 people made 2 contributions - 1 person made 3 contributions
Result is: { 2 => 2, 1 => 3 } Here is what I did: Contributor.joins(:contributions).order("count(contributions.id) asc").group("contributor.id").count
This gives me how many contributions by each contributor, but not what I'm looking for. |

I've tried using gem 'resque-scheduler', '~> 2.5.5' with no luck (saw that recommended somewhere on Google). Also tried supplying the Github path with no luck. Not sure if it's relevant, but my Gemfile has a hyphen and the error has an underscore. Does that have anything to do with it? This is what my Gemfile looks like: source 'https://rubygems.org' gem 'rails' gem 'postgresql' gem 'haml' # Base-62 conversion library gem 'radix62' # Generated views will default to haml gem 'haml-rails' gem 'resque' gem 'resque-scheduler' gem 'activeadmin', github: 'activeadmin' gem 'activeresource' group :development do gem 'pry-rails' end # Gems used only for assets and not required # in production environments by default. group :assets do gem 'sass-rails' gem 'coffee-rails' gem 'therubyracer', :platforms => :ruby gem 'uglifier' end gem 'jquery-rails'

| Testing pessimistic locking with Rails Posted: 30 Jun 2016 04:29 AM PDT To get a better understanding of pessimist locking (with InnoDB), I tried to run this code in my Rails application: Thread.new do Account.transaction do account = Account.lock(true).first account.balance += 250 account.save! end end Thread.new do Account.transaction do account = Account.lock(true).first account.balance += 500 account.save! end end
It actually works, account.balance then contains 750, then 1500 on the next hit. Without locking, it just takes the last thread into consideration and the result is 500. Is that a dumb test to try out the difference between locking or not? I think I understand the principle of pessimist locking, but not sure though. |

| Funding source in transfer request using DwollaV2 in rails application Posted: 30 Jun 2016 03:44 AM PDT I'm trying to implement money transactions by user's email in my rails application using DwollaV2. The problem is I don't really understand from the documentation what has to be a funding source in the request body and always getting error "Funding source not found". Steps I'm performing: - Create Dwolla client with key & secret
- Get code from Auth
- Exchange code for a token, here's how it looks:
# access_token="LQPX..."refresh_token="jjLS..." expires_in=3590 scope="send|fundings" account_id="3481..."> 4.Create request body: id = token.account_id email = test@gmail.com request_body = { _links: { destination: { email: "mailto:#{email}" }, source: { href: "https://api.dwolla.com/funding-sources/#{id}" } }, amount: { currency: 'USD', value: amount.to_s } }
5. Perform POST request: token.post 'transfers', request_body
Would be grateful for any help or suggestions. |

| Rails web application need to send Desktop Notification targeted to its registered user Posted: 30 Jun 2016 03:13 AM PDT Ruby 2.3.0 Rails 4.2.6 In my web application I need to send Desktop Notifications to a target user when a particular task is assigned to him. Use-case goes like following: Let's assume following users are available in the system: - System Admin (admin@example.com)
- John (john@example.com)
- Peter (peter@example.com)
Let's assume system-admin has created following tasks Task 1) Book an appointment with Bank executive Task 2) Book a flight to New York Now system-admin assigns Task 2) to Peter and Task 1) to John Now there are two scenarios: Scenario 1) - Users are using the web-application live i.e. they are logged-in. In this case when system-admin assigns the Task 2) to Peter, Peter should receive a Desktop Notification saying You are assigned this task probably with a link to the task. Clicking the link to the task takes Peter to the Task Details page which might contain more details about the task. Similar should be the behaviour when Task 1) is assigned to John by system-admin. Scenario 2) - Users are offline In this case when system-admin assigns the Task 2) to Peter and Task 1) to John both of them should see the Desktop Notification when they log-in to the web-application. I don't know how much feasible the Scenario 2) is and whether it is possible to implement it or not. I have no idea about how to implement Desktop Notifications. This is my first attempt and hence clueless. I tried to search the web for possible solutions but I ended up on following libraries: and some more article links. But all of these focused on how to create and display a Notification. But none of them was convincing enough in guiding me to implement my use-case. Hence decided to seek help from the SO community. I also found an app Noti and which has published a Ruby gem and a tutorial about implementing Desktop Notifications in a Rails app with Noti. Going through it seems like Noti is what can help me out in my case but Noti can work only when my web application users install Noti's native desktop application on their machine. Thus I am reluctant in pursuing it and am finding for out-of-the-box alternatives. So can I please get the guidance from the community on my requirement I have mentioned above and what tools or libraries can help me achieve my goal. Thanks. |
| Missing method notifications belongs_to has_many Posted: 30 Jun 2016 03:08 AM PDT I'm having a lot of trouble getting associations to work in Rails 4.2.2. I have a project and this project can have lots of notifications. What I would like to have is that I can add notifications with: @project.notifications.build(icon: "icon.jpg", text: "lorem ipsum")
So I have added belongs_to to the Notification model I've created, which you can see below: class Notification < ActiveRecord::Base belongs_to :project validates :icon, presence: true validates :text, presence: true, length: { maximum:75 } validates :project_id, presence: true enum status: {green: 1, orange: 2, red: 3, dark_grey: 4, light_grey:5} end
And added the has_many association to the Project model: class Project < ActiveRecord::Base belongs_to :user has_many :notifcations before_save :set_start_date validates :name, presence: true, length: {maximum: 255} validates :website, presence: true WEBSITE_REGEX = /\A(?:(?:https?|http):\/\/)(?:\S+(?::\S*)?@)?(?:(?!10(?:\.\d{1,3}){3})(?!127(?:\.\d{1,3}){3})(?!169\.254(?:\.\d{1,3}){2})(?!192\.168(?:\.\d{1,3}){2})(?!172\.(?:1[6-9]|2\d|3[0-1])(?:\.\d{1,3}){2})(?:[1-9]\d?|1\d\d|2[01]\d|22[0-3])(?:\.(?:1?\d{1,2}|2[0-4]\d|25[0-5])){2}(?:\.(?:[1-9]\d?|1\d\d|2[0-4]\d|25[0-4]))|(?:(?:[a-z\u00a1-\uffff0-9]+-?)*[a-z\u00a1-\uffff0-9]+)(?:\.(?:[a-z\u00a1-\uffff0-9]+-?)*[a-z\u00a1-\uffff0-9]+)*(?:\.(?:[a-z\u00a1-\uffff]{2,})))(?::\d{2,5})?(?:\/[^\s]*)?\z/i validates :website, format: { with: WEBSITE_REGEX }, if: 'website.present?' validates :industry, presence: true validates :user_id, presence: true end
But when I open de rails console and go enter the following: project = Project.last #returns project project.notifications.build(icon: "icon.jpg", text: "lorem ipsum")
I get the following error: NoMethodError: undefined method `notifications' for #<Project:0x00000005916ef0> Did you mean? notifcations
