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.

HABTM multi "and" query Posted: 30 Jun 2016 06:35 AM PDT I have Article and Tag records with HABTM relation. I need to filter Article by array of tags with "and" query. With tags below, I need every "Salami" and "Pizza" that are expired. tags = ["Salami", "Pizza", "Expired"] // items could be any number from 1..n I came up with following but this returns every "Salami" and "Pizza" which aren't expired. This also return every items expired which aren't Salami nor Pizza def tags_query render status: 200, json: Article.includes(:tags).where('tags.name' => params[:tags] ) end

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 Using rails5.0.0.rc1

Can't access css and js from public folder in development mode in Rails 4.2.6 Posted: 30 Jun 2016 06:02 AM PDT My issue is almost the same as this one. I couldn't access my css and js which are under public folder in development mode. This is how I mentioned in layout: <link rel="stylesheet" href="/college/css/bootstrap.css"> <link rel="stylesheet" href="/college/css/main.css"> <%= javascript_include_tag "application" %> <script src="/college/js/admin.js"></script> <script src="/college/bootstrap.min.js"></script> I have tried adding config.serve_static_files = true in development.rb file, but no use. Also there is no error listed in the logs. What might be the mistake?

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.

Ruby on Rails, using activerecord to get all records that have a specified field containing a string in my array Posted: 30 Jun 2016 06:00 AM PDT So i know i can do something like this Model.Where('field LIKE ?','%mystring%') to get all records containing my string inside my specified field. But is there to make it check through an array of strings rather than a single string ?

ruby mongomapper multiple belongs_to on same model Posted: 30 Jun 2016 05:42 AM PDT I have a situations where i need to have a model (message) belonging to two entities which are independent document in each other(sender and receiver). I am currently starting our new app development on ROR and i have already gone through the comparison between mongoid and mongomapper according their use cases, pros and cons. i have settled on mongomapper. I am deciding data models for mongodb and came down to a situation where i need to have a model associated with two other entity. class Sender include MongoMapper::Document many :messages end Class Reciever include MongoMapper::Document many: messages end Class Messages include MongoMapper::Document belongs_to: Sender belongs_to: Reciever End Will this kind of relationship is supported in mongomapper as i have heard that mongomapper is well maintained by community and lot of quirks while working with associations. I am new to ROR. Any help is appreciated

Detect ngrok from Rails Posted: 30 Jun 2016 04:42 AM PDT I am using ngrok in order to test my Rails application integration with PayPal. Since my application works with subdomains, I would like to detect when call is made from ngrok so I can apply a different behaviour. Is there any way to configure ngrok to pass some information so I can detect the call comes from there? Or any other way to know that ngrok stands behind the call?

Upgrade Rails 3.2 to 4.2 -> cannot load such file -- resque_scheduler/tasks Posted: 30 Jun 2016 04:36 AM PDT I'm trying to upgrade my Rails 3.2 project to Rails 4.2, including all of my dependencies in my Gemfile.

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.

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: Users are using the web-application live i.e. they are logged-in. Users are offline. 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: HTML5-Desktop-Notifications - This looks like Deprecated notify.js notification.js 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

How can I repeat a POST request in Rails? Posted: 29 Jun 2016 08:23 AM PDT I have some error-handling code that sometimes needs to do some stuff and then re-try the current request. This works fine when it's a GET request, but not otherwise. In other words, I can't redirect_to request.path when request.post? is true. Is there some way I can take the current request object, be it GET, POST, PATCH, or whatever, and just restart it?

Accessing value of select_tag in Controller Posted: 29 Jun 2016 08:16 AM PDT I am having trouble accessing a value of select_tag in my controller. I have the following select_tag in my view: = select_tag "yessir", options_for_select([ ["No Teardown Time","0"],["15 Minutes", "15"], ["30 Minutes", "30"], ["45 Minutes", "45"], ["60 Minutes", "60"], ["75 Minutes", "75"], ["90 Minutes","90"], ["105 Minutes", "105"],["120 Minutes","120"]], @event.teardown_time), {:prompt => 'Teardown Time'} And I try to access it in my controller like such: a = params["yessir"] I have also tried a = params[:yessir] But in either case I keep on getting undefined local variable or method `params' for #. Any suggestions? Cheers~

Capistrano 3 does not restart my rails app after deployment Posted: 29 Jun 2016 08:14 AM PDT I use the following deploy.rb : # config valid only for current version of Capistrano lock '3.4.0' set :application, '*****' set :rails_env, 'production' set :repo_url, 'admin@test.*******.***:/srv/outils/repos/*****' set :scm, :git namespace :deploy do after :restart, :clear_cache do on roles(:web), in: :groups, limit: 3, wait: 10 do # Here we can do anything such as: # within release_path do # execute :rake, 'cache:clear' # end end end #after 'deploy:publishing', 'deploy:restart' end after 'deploy:publishing', 'deploy:restart' It correctly deploy the app but does not restart it. What should i modify to make it restart? There is no message, error or otherwise, about the restart.

Rails instance object valivate Posted: 29 Jun 2016 08:26 AM PDT I was trying to practice Rspec, but seems I was confused about some rails part. Here is Zombie.rb class Zombie < ActiveRecord::Base validates :name, presence: true has_many :tweets def hungry? true end end It seems when I create a Zombie instance, it will check the name attribute. So, I wrote these Rspec code. it 'should not be hungry after eating' do @zombie = Zombie.create @zombie.should_not be_valid @zombie.hungry?.should be_truthy end Why it will pass? If the @zombie is not valid, why @zombie.hungry? will still return true

MultiJson Oj as a default instead of json_pure in Rails 4? Posted: 29 Jun 2016 08:08 AM PDT Is there a way to force Rails 4.2.5 to use MultiJson with Oj by default? I have it in Gemfile and running MultiJson.engine in the console shows MultiJson::Adapters::Oj. But on one page I'm getting following error related to encoding and it is using json_pure instead of MultiJson: /gems/ruby-2.3.1@report/gems/json_pure-1.8.3/lib/json/common.rb:223:in 'encode'

Rails partial for collection, only display certain things for first element Posted: 29 Jun 2016 08:07 AM PDT I have a collection of elements I'm rendering in a partial, but I only want to display a certain element with the very first element. My specific instance is displaying email addresses but I only want the email icon to show once next to the first instance (similar to how the Android Contacts app does). I have a very "hacky" solution that uses instance variables in the view, which is not a good practice. But I'm struggling to find a cleaner way to implement what I want. The controller: @email_addresses = EmailAddress.order(:primary) # primary is a boolean value The partial: # views/email_addresses/_email_address.html.erb <div class="email-address"> <% unless @email_icon_displayed <% @email_icon_displayed = true %> <div class="email-address-icon"> <span class="icon email"></span> </div> <% end %> <div class="email-address-value"> <%= email_address.value %> </div> </div> Calling partial in view: <%= render partial: "email_addresses/email_address", collection: @email_addresses %> This works properly and only displays the email icon for the first element, but instance variables in the view seems like a bad idea.

Require an OS package in capistrano Posted: 29 Jun 2016 08:13 AM PDT I need to verify that an OS package is installed after deploying using capistrano (it's a rails project, in case it matters). I'd like to support the major linux distros and OS X. Fortunately, the name of the package is the same on all platforms. I've thought adding a capistrano task, something like (untested code): %w(yum apt-get brew).each do |manager| path = `which #{manager}`.chomp if path && path.size > 0 `#{path} install -y #{PKG}` return end end Inspired by this question. Is there a better way? I've thought checking uname, but it doesn't always have the distro, just "Linux". I also thought using lsb_release or listing files in /etc/*-release, but not all distros support it (e.g. centos).

Model evaluates to nil if declared within 'if' block Posted: 29 Jun 2016 08:12 AM PDT I have a rails app that has a model chart, and a chart has a datasource. A datasource may have many datapoints. In my chart create method I have the following line: @chart = Chart.new(chart_params) @chart.datasource = Datasource.find_by_id(2) @chart.save This works fine - although it's not what I'm trying to do. What I'm trying to do is the following: if @chart.id == 2 @chart.datasource = Datasource.find_by_id(2) @chart.save end When I do that, however, I get NoMethodError in Charts#show undefined method 'datapoints' for nil:NilClass The error in my Charts#show is generated starting with: <% @chart.datasource.datapoints.each do |c| %> dates.push( "<%= c.date %>" ) counts.push( <%= c.count %> ) <% end %> Remember, this works perfectly fine if I hard-code the datasource id outside of an if block, wondering what could be causing this.

Devise sign_in resource works even without importing module Posted: 29 Jun 2016 07:39 AM PDT So, I was customizing devise in a custom sign up page which required me to sign_in a user after creating the account along with some other operations.

Conflicting View Logic Posted: 29 Jun 2016 07:56 AM PDT I have a show page where I need to both show the student's units and create a unit for them. However an error is being incurred when trying to do both. In my controller def show @student = Student.find(params[:id]) @unit = @student.units.build @units = @student.units end In my view <%= simple_form_for @unit, url: student_units_path(@student) %> # form... <% end %> <% @units.each do |unit| %> <tr> <td><%= unit.course %></td> <td><%= unit.mailing_date.strftime('%m/%d/%y') %></td> </tr> <% end %> The unit.course call works and any call that is only the first child of unit, however when I call a second method on unit I get this error: undefined method `strftime' for nil:NilClass despite knowing that the unit exists, hence the first call working

Rails cache Permission Denied when cache is very large Posted: 29 Jun 2016 07:08 AM PDT My app uses extensive rails caching, and all the cache keys are created and used by the same application, which has full rights to the cache folder. However, occasionally when the cache gets particularly large (large uptick in use within the cache expiration window), I start getting permissions errors when accessing the cache fragments using Rails.cache.fetch: Permission denied @ unlink_internal Clearing the cache "fixes" the problem, until it gets large again. Is there a theoretical limit to the size such a cache can be, or could there be some other cause?

Rails Active Record Omitting Where Clause Posted: 29 Jun 2016 08:19 AM PDT I have an Active Record query that sits inside of a gem. Database used is postgres. Client.where(date:@date,client:@business_id) The gem uses a get request to pull this data. When there are too many values in @business_id, the URI is too long. Gem does not have post requests. Workaround: The business problem is when all the @business_id get passed to the app. I could have an "all" button, that triggers all the client values to show. I would need to ignore the client:@business_id part of the query. How could I construct the query so that when all of the @business_id need to be passed, it ignores the client:@business_id part of the query?

Seed Database with Data for Each User Posted: 29 Jun 2016 07:06 AM PDT I am trying to figure out the best way to populate the database for each user. My end target is to have each user who has_many goals have a list of prepopulated goals when the user is created. The issue I see with seeding is that this will only create ONE set of goals for every user to "share" and not an individual set of goals for each user with the same initial data. This is my current layout: weekly_goals table user_id title status User.rb has_many :weekly_goals WeeklyGoal.rb belongs_to :user #List of all goals hardcoded in Am I going about this with the wrong thought process? Is there a better way to do what I'm asking? Thanks!

Ruby Workflow Issue During Migration Posted: 29 Jun 2016 07:00 AM PDT I am using Ruby Workflow in my ActiveRecords using Gem: Workflow Existing Running Code contains: I am having an ActiveRecord: X I am having two Migrations already: (Ref1) CreateX migration (which creates table X) (Ref2) CreateInitialEntryInX migration (which creates one entry in table X) New Changes: Now I wanted to add workflow in ActiveRecord X, hence I did: (Ref3) I added the workflow code in ActiveRecord Model X (mentioning :status as my workflow field) (Ref4) AddStatusFieldToX migration (which adds :status field in table X) Now when I run rake db:migrate after the changes, the (Ref2) breaks cos Migration looks for :status field as it is mentioned in ActiveRecord Model in the Workflow section, but :status field has not been added yet as migration (Ref4) has not executed yet. Hence, all the builds fail when all migrations are run in sequence, Any solution to this? I do not want to resequence any of the migration or edit any old existing migrations.

Multiple rails forms on same page: clicking submit button per form always works in safari, sometimes works in firefox Posted: 29 Jun 2016 08:06 AM PDT On an index page I have a table with a bunch of listed items. Each <tr></tr> within the table's <tbody>not only lists each item, but also allows you to update that item click edit to take you to the edit screen for that item Here is a picture: Within development in safari: I can successfully update each listed item and it all works just fine. However: when running my feature spec with capybara and selenium-webkit (which uses firefox): It appears that capybara finds the submit button ok and even clicks it But then nothing happens. For some reason the form appears to not be submitting when that update button is clicked. To make things even more strange: in development mode while testing with firefox, clicking the update button works sometimes. Sometimes it doesn't work and I have to refresh the page, and then it works. I tried putting a binding.pry in right before clicking the Update abc button in order to manually click the button at that step. I noticed that clicking the button manually was not submitting the form either. Here is my relevant spec: scenario "within the index page", js: true do select 'some selection', from 'item_1_jazz' select '12345', from 'item_1_something' # I attempted putting a binding.pry here, and noticed that clicking the update button still wasn't submitting the form find("#update_some_item_1_btn").click expect(page).to have_content 'The item was successfully updated.' end Update Here are my buttons within the form: <td class="btn-group"> <%= f.submit 'Update abc', class: "btn btn-success btn-sm", id: "update_#{dom_id(item)}_btn" %> <%= link_to edit_item_path(item), class: "btn btn-info btn-sm" do %> <i class="fa fa-pencil"></i> Edit <% end %> </td> Question: In firefox: Capybara appears to find the submit button just fine and even click it. But why isn't Capybara able to submit the form within Firefox? Also: why in development mode with firefox does the button only work sometimes? It appears something is stopping the form form from submitting.
