Minitest - calling a mocked instance method from within another instance method I've come across some weird behavior in Minitest::Mock and can't figure out what's the reason behind it. Minitest::Mock Say I have this class A that has a method b that calls method c : b c class A def b c end def c 1 end end I would like to mock the c method to return 2 instead of 1: c require 'minitest/autorun' a = Minitest::Mock.new(A.new) a.expect(:c, 2) But for some reason b still returns 1: b > a.b => 1 Obviously calling c directly will work: c > a.c => 2 > a.c MockExpectationError: No more expects available for :c: Why is the expectation on c not being invoked when calling it from within the instance? c 1 Answer 1 This is how Minitest::Mock works; the mock object is a wrapper around the "real" instance of A , and defined expectations intercept the...

Optimize with joins, order, distinct on current active records / sql query I am using ruby on rails 4 and postgres currently, and making distinct and sorting as in the code below. I just have a feeling is not right and not optimized because it seems to be doing all this with an array. How could I combine this all into one activerecords query ? ads1 = Advertisement.where(property_id: nil) .where(target_address_city: [property.address_city, ""], target_address_state: [property.address_state, ""], target_address_country_id: property.address_country_id) # return advertisement belongs to the property ads2 = management.property.advertisements #combine both results combine_ads = ads1 + ads2 #remove ads duplicate uniq_ads = combine_ads.uniq { |ads| ads.id} # sort by created_at desc uniq_ads = uniq_ads.sort_by { |ads| -ads[:id]} # do pagination final_ads = uniq_ads.paginate(:page => pa...

Rails 5 Jquery stops working on redirect So I'm working with Rails 5.1 to create a web app and I'm using a CSS checkbox hack to open a navigation menu. I have a button (on root_path) which, when clicked, uses Jquery to check the box from another area. It works when going to the page, but when I redirect to another page, it stops working. But the console still outputs true/false when I click the button logging whether the checkbox is checked or not. So the button functions seem to work on-click, but the checkbox doesn't show as checked. I've spent a lot of time playing with the jquery, turning off turbolinks on the home button which refreshes, etc. Curious if anyone has a way to get around this or if rails 5 is finicky with this stuff. Here is the snippet for the two buttons in _index.html.erb <div class="index__content--buttons"> <%= link_to("Find Out More", root_path, :class => "btn btn--primary", data: { no_turbolink: tr...

react-rails asset pipeline image path I'm using the react-rails gem, and I'm having trouble figuring out how to load images from the asset pipeline. I handle this currently by using the .js.jsx.erb extension, but as far as I know this is unconventional.

How to sandbox a rails application so that dependencies are installed locally without having to re-run bundle install I'm trying to sandbox a rails application so that i can port it over to other machines without having to re-bundle. Is there a way for rails to pull in dependencies locally to self-sustain? 1 Answer 1 All dependencies are stored in the Gemfile.lock. All gems stored in ruby directory. You can run once bundle install to create Gemfile.lock. Then save Gemefile.lock and pack a directory with gems. After it you can copy your pack to server and deploy you application. but if you move directory to a different environment, say docker, and say you don't have internet, you wouldn't be able to bundle install. – user2167582 Jun 30 at 13:34 ...
