| Rails order / sort dates based on two different dates Posted: 23 Jun 2016 07:53 AM PDT Each record contains two fields - field1 and field2. Both contain dates. For reach record: 1 field might have been filled in, for another it might be 2 of the fields or none at all. I'd like to in the most efficient way possible order them based on this. So it would compare field1 and field2 for a record and find which one has the latest date. It would then list all of the records in order based on this and then display the records that don't have any kind of entry. I had it sorted for just field1 like this: order("CASE WHEN field1 IS NULL THEN 1 ELSE 0 END, field1 desc"
But when I try and introduce field 2 into the query it doesn't give me the results that I would expect. Any ideas? |
| Installing bundler gives me "you don't have write permissions" error Posted: 23 Jun 2016 07:31 AM PDT I had used ruby version manager (rvm) to install a new version of ruby. Running the command rvm rubiesshows all the version of rubies that are installed. The list is given below. rvm rubies ruby-1.9.3-p551 [ x86_64 ] ruby-2.1.5 [ x86_64 ] ruby-2.2.4 [ x86_64 ] * ruby-2.3.0 [ x86_64 ] ruby-2.3.1 [ x86_64 ] # => - current # =* - current && default # * - default
I tried to run the command bundle exec rake rb:mgirate and I get the following error. /usr/local/rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/dependency.rb:319:in `to_specs': Could not find 'bundler' (>= 0.a) among 5 total gem(s) (Gem::LoadError) Checked in 'GEM_PATH=:/nix/.nix-profile/lib/ruby/gems', execute `gem env` for more information
The error states that bundler isn't installed. I ran the command gem install bundle and I get the following error. ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /nix/.nix-profile/lib/ruby/gems directory.
It says that I don't have write permissions. I googled the error and it has something to do with updating ruby and ruby version. The reason why I updated to a new ruby version was because heroku run rake db:seed wasn't seeding data in production. I though it might be due to compatibility issues. Therefore, I decided to update to the new version of ruby. The servers, postgresql and everything else works fine. I can't run bundle because I can't install the gem. Any hep would be greatly appreciated. Thanks! |
| Rails redirect_to loses the https protocol and goes to http Posted: 23 Jun 2016 07:27 AM PDT When using redirect_to example_path in the controller the protocol gets changed to http. I want the protocol to remain the same as the original request e.g. if I'm using https I want to be redirected to https://example_path... and if I'm using http I want to be redirected to http://example_path... I know I can use config.force_ssl = true but I want ssl to be optional. |

| Rails: ActionController::UrlGenerationError, No route matches, missing required keys Posted: 23 Jun 2016 07:13 AM PDT The following error is displayed when I try to create new data. ActionController::UrlGenerationError (No route matches {:room_id=>nil, :action=>"index", :controller=>"events"} missing required keys: [:room_id]):

The reason why I designate new_room_event_path(1) is that this is first time to create data. events_controller.rb before_action :load_room def new @event = Event.new @event.room = @room @event.build_amount @event.amount.schedule = @room.schedule @event.amount.room = @room end private def load_room if Room.exists?(id: params[:room_id]) @room = Room.find(params[:room_id]) else @room = Room.new end end

| rspec factory girl pass association to association Posted: 23 Jun 2016 06:26 AM PDT Given these Rails models: class Human has_many :pets has_many :vet_visits end class Pet belongs_to :human has_many :vet_visits end class VetVisit belongs_to :human belongs_to :pet end
I need an rspec factory to make a VetVisit. But: FactoryGirl.define do factory :vet_visit, class: 'VetVisit' do association :human, factory: :human association :pet, factory: :pet end factory :pet, class: 'Pet' do association :human, factory: :human end factory :human, class: 'Human' do after(:create) do | human | create :pet, human: human end end end
results in a vet_visit with a human and a pet which are not each other's respective pet/human. How do I make a factory which creates a vet_visit which has a pet with a human which is the same human as referenced by the vet_visit? To clear any doubt, I am not in fact making a vetinary system, this is an abstract example from a more complex system, removing the human and doing vet_visit.pet.human in the code is not suitable |

| Bulk insert of parent/children at the same time Posted: 23 Jun 2016 06:44 AM PDT I am trying to do a bulk insert of a pair of parent/child models to MySQL DB tables, but it seems there is no way I could do it with the standard ActiveRecord feature. So, I tried activerecord-import gem, but it does not support recursive insert for MySQL either... # Book has_many authors / Author belongs to Book books = [] 10000.times do |i| book = Book.new(:name => "book #{i}") book.author.build(:name => "author #{i}") books << book end Book.import books, recursive: true # THIS DOES NOT WORK
I also tried to achieve it with raw SQL, but I was not unable to find a way to keep the reference of each parent/child because at the time I want to insert the child data, its parent have not had its id yet.
Dose anyone know how I could solve this problem? |

| Why should I use post_via_redirect? Posted: 23 Jun 2016 05:36 AM PDT In Rails' guide for Integration test there's an example with post_via_redirect. But why would one use "via_redirect" instead of plainly post? require 'test_helper' class UserFlowsTest < ActionDispatch::IntegrationTest test "login and browse site" do # login via https https! get "/login" assert_response :success post_via_redirect "/login", username: users(:david).username, password: users(:david).password assert_equal '/welcome', path assert_equal 'Welcome david!', flash[:notice] https!(false) get "/articles/all" assert_response :success assert assigns(:articles) end end

| incompatible character encodings Posted: 23 Jun 2016 05:26 AM PDT I am getting this issue "ActionView::Template::Error (incompatible character encodings: UTF-8 and ASCII-8BIT)", from client browser, so i am bit confused, where this is happening actually, one place is <%= form_for(resource, :as => resource_name, :url => session_path(resource_name), html: { class: "signup" }) do |f| %>
but before this line, i am seeing one line is like this Started GET "/checkstatus/status?utf8=�??&status_id=12686" Parameters: {"utf8"=>"\xE2??", "status_id"=>"12686"}
is there any issues with clients browser? in these two statements, what will be the most change to occur this? |
| Inline C output value store on rails controller Posted: 23 Jun 2016 05:02 AM PDT I am using inline C to get some output. What I am trying to do is execute the inline C code and render its output to rails view via controller. The code snippet for inline C is: class Something inline(:C) do |builder| builder.c 'int test1() { char array[20] = "-------Hello from Ruby!------\n"; printf("%s", array); return array; }' end end
Object is created in the controller of the rails application this way. def index something = Something.new @something = something.test1 end
Now, when I try to store output value of the inline C, it just is not applicable while the output is displayed on the rails log(not on the log file). I am sure that the value displayed is via return array; of the Something class. The index method has @something instance set which just stores some value like 4421355280 , but not the value. ie "-------Hello from Ruby!------" I have an index to render the corresponding controller action. <h1>Travel</h1> <h3><%= @something %></h3>
How can I possibly store output value "-------Hello from Ruby!------" into @something? Output of inline C Thanks in advance. |

| how to continue after the nested model forms railscasts? Posted: 23 Jun 2016 05:09 AM PDT I followed the railscasts nested model form part 1, making some changes to have it work in rails 4. Basically, I created 3 models: Quiz, Question, and Answer, and they all belong_to the model intuitively above them. A form in the new action is used to create the quiz itself. However, I'm at a bit of loss on how to proceed now. After creating the quiz, the show view looks like this:  done by iterating through @quiz.questions and @quiz.questions.answers and just displaying them on the page with their respective content attributes. That's great for displaying just the questions and answers, but it doesn't accept user input at all. How do I make it so the user can use radio buttons to select an answer, and have it submit SOMEWHERE to save the results for grading and future reference for the user? I've actually tried to create a form simply within the show action and have it save to another model but I got stuck extremely quickly. I'm finding it really difficult to both display the results AND accept user input for the displayed results. I also can't figure out a good way to save this data. Making another 3 models with the equivalent of Questions having something like a user_answer attribute seems difficult to implement and messy. I'm a beginner of the grandest caliber so any help would be great! |
| Cleaning scraped <a href> rails Posted: 23 Jun 2016 06:21 AM PDT I have scraped data from a website and entered it into an array using the code below: def process_course_details(course_details) details_array =[] details_link = true entry_link = true details_info = {} # Sets all data in hash details_info[:url] = clean_link(course_details.search('div.coursedetails_programmeurl a')) details_array.push(details_info) print_details_info(details_info) entry_link = course_details.search('ul.details_tabs').first end
The code above stores the element being pulled as such: <a href="http://www.abdn.ac.uk/study/courses/undergraduate/C8R1/">View course details on provider's website</a>
But I'd like to clean the above to the below: http://www.abdn.ac.uk/study/courses/undergraduate/C8R1/

How can I have both of them work with each other, for example if I send an encrypted data to java app from rails app it should be able to decode it and vice-versa. |
