Heroku & Godaddy Naked domain configuration not redirecting Posted: 21 Aug 2016 08:34 AM PDT I am using ssl with my heroku app and I am using godaddy as my host. My problem is, if I type www.mydomain.com, it redirects to (https)://www.mydomain.com which is ok. But when I type mydomain.com it redirects to (http://)mydomain.com. So I understand that is the problem of naked domain configuration. Till now, I set the heroku custom domain as; www.mydomain.com as domain name and smt-somenumber.herokussl.com as dns target. On the godaddy side, as Cname I put www and smt-somenumber.herokussl.com. as forwarding I put (https://)www.mydomain.com. Do you think should I put (https://)smt-somenumber.herokussl.com as forwarding instead of (https://)www.mydomain.com ?

ruby program functionality Posted: 21 Aug 2016 07:32 AM PDT I'm new to ruby and struggling to understand the full functionality of this ruby script. I want to understand it and then rewrite into java or R. lastly, I got the script from hadley Github. So I have the following questions: . I don't really understand the ID parameter values. Is it the same from the movies table. If so why is it a string. . I don't really understand how the genres and the genres of interest are being mapped. I understand the sql bit except in the where clase in partical "#{id}" and flatten.to_set(is this turning genres to a set) genres_of_interest = ["Action", "Animation", "Comedy", "Drama","Documentary", "Romance", "Short"] $ratings_map = {"." => 0, "0" => 4.5, "1" => 14.5, "2" => 24.5, "3" => 34.5, "4" => 44.5, "5" => 45.5, "6" => 64.5, "7" => 74.5, "8" => 84.5, "9" => 94.5, "*" => 100} def genres_binary(id, db) genres = db.execute("SELECT genre FROM Genres where movie_id = {id};").flatten.to_set $genres_of_interest.map { |genre| (genres.include? genre) ? 1 : 0} end db = SQLite3::Database.open "movies_sqlite3.db" db.results_as_hash= true sql = " SELECT Movies.* FROM Movies WHERE length > 0 and imdb_votes > 0 ORDER BY title" i = 0 File.open("movies.tab", "w") do |out| out << [ 'title', 'year', 'length', 'budget', 'rating', 'votes', (1..10).map{|i| "r" + i.to_s}, 'mpaa', $genres_of_interest ].flatten.join("\t") + "\n" db.execute(sql) do |row| puts i if (i = i + 1) % 5000 == 0 out << [ row["title"], row["year"], row["length"], row["budget"], row["imdb_rating"], row["imdb_votes"], ratings_breakdown(row["imdb_rating_votes"]), row["mpaa_rating"], genres_binary(row['id'], db) ].flatten.join("\t") + "\n" end end E.g of the Movies table data id/title/year/budget/length imdb_rating/imdb_votes/imdb_rating_votes/ mpaa_rating these are the columns 9/#1 Serial Killer/ 2013/30000/87/6.1/33/2000.02002/PG-13 columns data E.g of the Genre table data id/movie_id/genre these are the columns 440/1816/Talk-Show columns data Please for give me, this is my first question ever on stack overflow. Thanks

How to solve undefined method `to_key' error with collection_select - RoR Posted: 21 Aug 2016 08:10 AM PDT I'm trying create a collection select, but I got this error: NoMethodError in Deal#selectuser undefined method `to_key' for #<Conversation::ActiveRecord_Relation:0x1059f4f8> My controller def selectuser @conversation = Conversation.involving(current_user) end My routes resources :deal, only: [:index, :new, :create, :selectuser] do collection do get "selectuser" # generate get "/deal/selectuser" end My view (conversation.html.erb) <%= form_for @conversation do |f| %> <%= collection_select(:conversation, :recipient_id, Conversation.all, :recipient_id, :title) %> <%= f.submit "Send", class: "btn btn-primary wide" %>

Shoulda Matcher and has_many through: undefined method `class_name' for nil:NilClass Posted: 21 Aug 2016 08:33 AM PDT I'm trying to test a :has_many through relationship with Rspec and Shoulda matchers. # student.rb has_many :presences has_many :calls, through: :presences # student_spec.rb it { should have_many(:presences) } it { should have_many(:calls).through(:presences) } #presence.rb belongs_to :call belongs_to :student #presence_spec.rb it { should belong_to(:call) } it { should belong_to(:student) } #call.rb has_many :presences has_many :students, through: :presences #call_spec.rb it { should have_many(:presences) } it { should have_many(:students).through(:presences) } Only the last of these test fails, returning: NoMethodError: undefined method `class_name' for nil:NilClass Did you mean? class_eval I found this issue, but the solutions proposed don't help me.

How to recursively send a nested hash the :[] method for any amount of levels? Posted: 21 Aug 2016 07:08 AM PDT Context: What I'm trying to do is make an Rspec shared_example called something like update response that checks a rails json response of an object and verifies that certain attributes are updated. The json response may or may not have nested attributes. The keys cannot be known ahead of time. Example: Say I have a hash, hsh = {one_deep: 123, nested: {a: 1, b: 2}}: I can dynamically send the hash a key if it's one level deep. def get_value(some_key) hsh.send(:[], some_key) end get_value(:one_deep) # => 123 I can access a nested hash if I hard code the method chain: def get_value(some_key, another_key) hsh.send(:[], some_key).send(:[], another_key) end get_value(:nested, :a) # => 1 get_value(:nested, :b) # => 2 Desired Endstate: # The hash key could be 'n' levels deep # # This doesn't work... maybe use recursion somehow? def get_value(*some_keys) some_keys.each do |key| hsh.send(:[], key) end end get_value(:nested, :a) # => should output 1 get_value(:nested, :b) # => should output 2

How to edit 'pagination gem' - Rails project Posted: 21 Aug 2016 06:34 AM PDT I need to edit my code to contain "target: "_self". How can i do it? This is my code. controller: @news = News.order(created_at: :desc).paginate(page: params[:page], per_page: 7) view: <div> <%= will_paginate @news, previous_label: "Назад", next_label: "Вперед" %> </div> THIS code don't work: <%= will_paginate @news, previous_label: "Назад", next_label: "Вперед", target: "_self" %>

Setting up CD for a Ruby on Rails project with Bitbucket Pipelines and Docker Posted: 21 Aug 2016 06:50 AM PDT I'd love to set up continuous deployment in Bitbucket Pipelines for a Ruby on Rails / PostgreSQL / Sidekiq project, but I'm struggling to get my head around how it all fits together, and specifically how to get postgres working inside a Docker image. I'm very new to Docker and Pipelines. In my Googling, Docker talks about using docker-compose to create a bundle, so I'd have a Postgres container and a Sideqik container, then link them with the app container. But I'm not sure what the difference is between a bundle and an image, and if Bitbucket Pipelines supports bundles. Eventually I want to set up deployments to a staging environment on Heroku, but for now just getting rspec spec to work in Pipelines would be nice. Is there an existing public image that has Ruby + PostgreSQL already set up that I can use? If not, where do I start? My current Dockerfile looks like this: FROM postgres:9.4 FROM ruby:2.3.1-onbuild RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs postgresql-client I then run docker build . and docker run -it my-image /bin/bash and the following commands: root@a84ad0e7c16b:/usr/src/app# postgres bash: postgres: command not found root@a84ad0e7c16b:/usr/src/app# psql psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

Heroku and database management for rails Posted: 21 Aug 2016 06:02 AM PDT I'm getting really close to putting up my first app. However, I'm worried that because I'm so new, I won't know how to manage my database properly. What's the best practice for managing a database on heroku? As in, backups for example. What if I really screw up something? Can I edit information like usernames, email addresses for users, etc directly in heroku or do I still do that from my terminal?

Rails: I have one controller with providing api service methods and another controller which access these api Posted: 21 Aug 2016 06:01 AM PDT I have one controller class APIABCController < ActionController::API .... def index ... end another controller on the same app class RestCallController < ActionController::Base def index ... end end Now I want to call APIABC Controller create method using rest from RestCall Controller. is it a good way please suggest. I do not want ajax to call. I want rest call from one controller to another controller methods

Getting assert_select to show me what an element actually was Posted: 21 Aug 2016 06:40 AM PDT I have the following test: test "users title when logged out" do get users_path assert_select "title", 'Correct title" end If we assume that users_path returns a page with <title>Wrong title</title>, then I get the following output: FAIL["test_users_title_when_logged_out", SiteLayoutTest, 1.0830602300120518] test_users_title_when_logged_out#SiteLayoutTest (1.08s) Expected at least 1 element matching "title", found 0.. Expected 0 to be >= 1. test/integration/site_layout_test.rb:37:in `block in <class:SiteLayoutTest>' I would like to replace the assert_select with something like assert_equal "Correct title", page.title so that the test failure message actually shows me what the page's title is, which would make tracing the problem much easier! (Naturally, the page shows the correct title in development mode…) However, page.title does not seem to be available, and my efforts at searching are only turning up stuff like "you can do it with Capybara", which is a bit bulky for this purpose! Is there a way to write this test so that it shows something like Expected page title to be "Correct title" but got "Wrong title" instead? [Edit for clarity: "Wrong title" is the title in the returned page, not a literal string — that is, I need the error to tell me what was actually returned.]

ActiveRecord: Skip validation when saving multiple objects Posted: 21 Aug 2016 08:07 AM PDT I know I can skip validations for an individual save, like this: User.new(name: 'John').save(validate: false) But how can I do that when saving multiple objects at once? Like this: Category.create([ { name: 'Apps' }, { name: 'Songs' }, { name: 'Movies' } ])

Always display locales in URL in rails 4 app Posted: 21 Aug 2016 05:08 AM PDT So I'm using i18n gem since my rails web-app has to be available in 2 languages : FR and NL. I made FR the default locale. My goal is to make sure that in any circumstances, the locales (ie. /fr/ or /nl/) are always shown in the URL. This is the case with the locale=nl but not the case with the locale=fr being the default locale. Here an example with a user story: a user arrived on the website and has to select his/her language: let's say "FR" ("FR" being the default locale) the user can now browse the site the user visit the page "Newsfeed" page and his/her URL is http://localhost:3000/newsfeed With this example, the URL should have been http://localhost:3000/fr/newsfeed (with the /fr/ in the URL) These are my routes: scope '(:locale)', constraints: { locale: /nl|fr/ } do resources :articles, :path => 'newsfeed', only: [:index, :edit, :destroy, :update, :new, :create] root to: 'languages#select' get '*path' => redirect('/') end In my application.rb I have config.i18n.default_locale = :fr config.i18n.available_locales = [:fr, :nl] In welcome page, where the users have to select their language, I have this <%= link_to "Neederlands", home_path(:locale => 'nl') %> | <%= link_to "Français", home_path(:locale => 'fr') %> To sum up, the URLs for the locale=nl will always show *http://localhost:3000/nl/newsfeed but for the default locale fr this is not the case and I need to fix that. Any idea?

Ruby on Rails: required parameters for model Posted: 21 Aug 2016 04:47 AM PDT Rails 5. I have model User and I want field "login" to be obligatory. What I did: class User < ApplicationRecord has_one :cart def create User.create(user_params) end private def user_params params.require(:user).permit(:login) end end But it doesn't work. I can save new user without login. irb(main):001:0> user2 = User.create begin transaction SQL (1.5ms) INSERT INTO "users" ("created_at", "updated_at") VALUES (?, ?) [["created_at", 2016-08-21 11:38:17 UTC], ["updated_at", 2016-08-21 11:38:17 UTC]] commit transaction => #<User id: 4, login: nil, created_at: "2016-08-21 11:38:17", updated_at: "2016-08-21 11:38:17"> How to fix it?

rake db:migrate invalid schema error for role that owns the schema Posted: 21 Aug 2016 04:39 AM PDT In my database.yml default: &default adapter: postgresql encoding: unicode pool: 5 timeout: 5000 database: postgres username: website development: <<: *default host: localhost password: password schema_search_path: "website_dev" In the postgres database as admin user I run ubuntu=# CREATE USER website WITH PASSWORD 'password'; CREATE ROLE ubuntu=# CREATE SCHEMA website_dev AUTHORIZATION website; CREATE SCHEMA ubuntu=# CREATE SCHEMA website_test AUTHORIZATION website; CREATE SCHEMA This should mean the user/role website can create tables in both the schemas website_dev and website_test, however rake db:migrate task fails with the error ActiveRecord::StatementInvalid: PG::InvalidSchemaName: ERROR: no schema has been selected to create in : CREATE TABLE "schema_migrations" ("version" character varying PRIMARY KEY)

Ruby on Rails difference between cookies[:remember_token] and cookies["remember_token"] Posted: 21 Aug 2016 04:43 AM PDT I have trouble undestanding the following situation: I am logging in and remembering my users by doing the following class SessionsController < ApplicationController def create user=User.find_by(email: params[:session][:email]) if user && user.authenticate(params[:session][:password]) log_in(user) params[:session][:remember_me]=="1" ? remember(user) : forget(user) redirect_to user else flash.now[:danger]="Invalid email/password combination" render "new" end end and module SessionsHelper def remember(user) user.remember cookies.permanent.signed[:user_id]=user.id cookies.permanent[:remember_token]=user.remember_token end all of which works fine. The thing that I don't understand though, is that in an integration test I have to use cookies["remember_token"] because in the following situation cookies[:remember_token] will return nil test "login with remember_me" do log_in_as(@user) assert_not_nil cookies["remember_token"] end Why does it return nil here and why does it not do that, if I use it for example as a parameter in a function inside of the Sessionhelper ( for example user.authenticated?(cookies[:remember_token]) ) P.S.: All of the code above comes from the Ruby on Rails Tutorial by Michael Hartl https://www.railstutorial.org/book (chap. 9.3.1)

Distinguisihing normal text from a youtube link Ruby on Rails Posted: 21 Aug 2016 07:04 AM PDT Hello all i am making a facebook clone using ruby on rails, I got a post form where i can write text and add a youtube link if i want and it works. However writing a text like "hello world"+ "www.youtube.com/etc" would be output as "hello worldwww.youtube.com/..." If i would just write "hello world" it would make a iframe for a youtube video which isnt correct either. My application helper def embed(youtube_url) youtube_id = youtube_url.split("=").last content_tag(:iframe, nil, src: "//www.youtube.com/embed/#{youtube_id}") end In my view <p><%= embed post.content %></p> My question is how could i make an if else statement to see if a youtube url is present, if so show the video but hav it on its own "block" and the text separate, if no video dont display the iframe and just the normal text that i write. Current output: <div class="post-content"> Hello World this is a sample text https://www.youtube.com/watch?v=X3dVpRAmq_8<br> <p><iframe src="//www.youtube.com/embed/X3dVpRAmq_8"></iframe></p> </div> I want to have it show like This is a sample text But a if /else statement, if there is a youtube video present add it but in its own tag, if no video is present just show the normal content i add

ruby on rails multiple step form Posted: 21 Aug 2016 05:24 AM PDT I have been doing some research into using multistep forms for my ruby on rails project, and have come across the wicked gem which seems to tick all the boxes. Upon further investigation, I see it is only good for showing/updating. does anyone know if its possible to use this gem for creating as I want to use the link for my signup process which will show a different set of fields depending on if the user selects they are a customer or a supplier?

How to insert serialized data into database using rails console Posted: 21 Aug 2016 04:53 AM PDT I added dynamic form fields to my rails app folowing the tutorial on this link railscasts or youtube and the source code github creating/updating using forms data works well as expected. however, I get the following error undefined method `humanize' for :author:Symbol when I try viewing the product inserted using console with this command for example Product.create(product_type_id: 1, name: "refactoring", price: 24.99, properties: {author: "Martin Fowler", page_count: 197, paperback: 1 } ) examining the database I noticed that the data inserted through the console doesn't get serialized example data submitted through form: --- !ruby/hash:ActionController::Parameters author: Martin Fowle page_count: '197' paperback: '1' example data submitted through console: --- :author: Martin Fowle :page_count: '197' :paperback: '1' How can I get this to work? I need this because I would also like to be able to update products using data from external sources, like data from APIs.

Simple_form - how to set a class for a wrapper when field is required Posted: 21 Aug 2016 05:39 AM PDT Is it possible to set a class, as an example 'field-required' for a input element wrapper? Ideally, i need to generate something like this: <div class="form-group"> <label class="col-sm-4" for="order_last_name">Last name</label> <div class="col-sm-8 field-required field-invalid" id="order_last_name"> <input name="order[last_name]"/> </div> </div> Notice that i need to insert field-required and field-invalid to the div containing <input.../>. So i also need to set error_class: to that div This how i set up the wrapper so far: config.wrappers :long_input, tag: 'div', class: 'form-group' do |b| b.use :html5 b.use :label, class: 'col-sm-4 control-label' b.wrapper tag: 'div', class: "col-sm-8", error_class: 'field-invalid' do |ba| ba.use :input, class: 'form-control' ba.use :error, wrap_with: { tag: 'p', class: 'help-block invalid-field-info' } end end error_class: does nothing when specified with nested wrapper, and how to add field-invalid class when validation fails?

Geokit Rails. Don't know where to begin? Posted: 21 Aug 2016 02:25 AM PDT I want to use the geokit gem for my app, but I have no idea where to begin. So, what I'd like to do is that my users can see if there is anyone around them in the 1 mile range. The first thing I wanted to do was add a column to my database, but I can't find what type I should use, and in the documentation, it says it's only about MySQL. class AddIndexToPageLatAndLng < ActiveRecord::Migration def self.up add_index :pages, [:lat, :lng] end def self.down remove_index :pages, [:lat, :lng] end end Now, how would I AddFieldsToUsers in Sqlite? Is it an integer or a string? Also, I'd like to know how to get the current user current address, so that I could use it in my index page. I'm thinking of something like this: User.find(:all, :origin=> @user.current_address, :within=>1)

Using MYSQL views in rails Posted: 21 Aug 2016 02:09 AM PDT I want to create a view on MYSQL table and found the gem https://github.com/anykeyh/rails_db_views but I did not understand how could I use it as I find the documentation not clear. Where should I put this code in my project (which file and directory ) Rails.configure do |config| config.rails_db_views.views_path += %w( /some/view/path ) config.rails_db_views.views_extension = "*.sql" config.rails_db_views.functions_path += %w( /some/function/path ) config.rails_db_views.functions_extension = "*.sql" end I would be thankful if anyone told the full steps to use it .

How to install new software onto a GCP flexible environment VM Posted: 21 Aug 2016 01:15 AM PDT I have a ruby on rails app running on a Google Cloud Platform VM running on the app engine flexible environment. It looks like it installs most of the software on the VM when I deploy the app with gcloud --project project-name preview app deploy I think it installs rails and other software from reading the temporary dockerfile it creates. It grabs the info for the dockerfile from the app.yaml file (I got this setup from following their tutorials). This was working fine for me but now I need to install ImageMagick onto the server to manipulate images on the site. Normally you do this by running sudo apt-get install imagemagick from the project directory. When I SSH onto the VM I cant find the project directory so that doesn't work. I have no idea how to get it to run sudo apt-get install imagemagick each time I make a new deploy to the site so it has the software on the new VM. As you might be able to tell I'm not very good with the server side of things and want to know what I'm supposed to do to get new software onto the VM the right way so its always there like ruby and rails etc.. are each time I make a new deploy.

How to post authenticity_token? Posted: 21 Aug 2016 01:56 AM PDT Now I use arduino sending data to rails in json format. But how to get authenticity_token and send it to rails? Where it should be written ? In json or http header? What the format should be? If I add protect_from_forgery :exception => :create In the controllers it works fine.But I do not want do disable the CSRF protection. This is my arduino code: client.println("POST /players.json HTTP/1.1"); client.println("Host: 192.168.1.3:3000"); client.println("User-Agent: Arduino/1.0"); client.println("csrf-param: authenticity_token"); client.println("csrf-token: V4gTh8yNdz9VMybUXkI6tHxzAHdfk3I+UoiXhxZWK0bkoh8iG5hVJ5sZOjzMAYLlwCwsXQQM102b1hF6TVyYJw=="); client.println("Connection: close"); client.println(lengthInfo); client.println("Content-Type: application/json"); client.println(); root.printTo(client); root.printTo(client) just send son. I found a similar question: HTTP request to update rails model from arduino @Okomikeruko Do you figure out how to send an authenticity token from Arduino?

Rails 4 - how to add an edit link for a nested resource Posted: 21 Aug 2016 12:12 AM PDT I'm trying to figure out nested routes. I have models called Project and Potential Use. The associations are: Project has_many :potential_uses accepts_nested_attributes_for :potential_uses, reject_if: :all_blank, allow_destroy: true Potential Use belongs_to :project belongs_to :user In my projects show, I'm trying to loop through each potential use. <% @project.potential_uses.each do |pu| %> <div class="row"> <p><%= pu.comment %></p> <strong><%= pu.user.formal_name %></strong> <%= link_to 'Edit', edit_project_potential_use_path(pu) %> <p style= 'border-bottom: solid; border-bottom-width: 1px'></p> </div> <% end %> When i try this edit link, I get an error that says: No route matches {:action=>"edit", :controller=>"potential_uses", :id=>nil, :project_id=>#<PotentialUse id: 14, comment: "asdf", project_id: 17, created_at: "2016-08-19 01:36:49", updated_at: "2016-08-19 01:36:49", user_id: 1, private_comment: false>} missing required keys: [:id] I've tried several different versions of the edit link. <%= link_to 'Edit', edit_project_potential_use_path(potential_use) %> <%= link_to 'Edit', edit_project_potential_use_path(project.potential_use) %> I can't find a way that works. My rake routes, shows this for the edit action: edit_project_potential_use GET /projects/:project_id/potential_uses/:id/edit(.:format) potential_uses#edit To my eye, this looks like I need to ask for plural references to the resources in the edit link (although it doesnt make sense to me), like so: <%= link_to 'Edit', edit_projects_potential_uses_path(pu) %> That formulation gives this error: undefined method `edit_projects_potential_uses_path' for #<#<Class:0x007fd4b7431b18>:0x007fd4b7430678> Did you mean? edit_project_potential_use_path edit_project_potential_use_url I can't see how to take this information and use it to write an edit link. Can anyone see what I've done wrong?

Rails attr_accessible atrribute isn't working isn't working [duplicate] Posted: 20 Aug 2016 11:23 PM PDT This question already has an answer here: How is attr_accessible used in Rails 4? 4 answers I'm doing this tutorial in Rails + Devise and I've stuck my head. There's this: # Setup accessible (or protected) attributes for your model attr_accessible :email, :name, :password, :password_confirmation, :remember_me validates :email, :presence => true, :uniqueness => I tried to translate it to Rails5 since attr_accesible isn't working Rails5 but seriously...I'm in the corner. What's the proper way to do here to make it work? I tried to define a method with permit parameters but it didn't really work out. I'd be really glad if you could give me a good hint on that!

Stripe charge or plan? Posted: 21 Aug 2016 12:22 AM PDT Right now, this is my create action for my charges controller: def create # Amount in cents @amount = 100 # Get the credit card details submitted by the form customer = Stripe::Customer.create( :email => params[:email], :source => params[:stripeToken] ) # Create the charge on Stripe's servers - this will charge the user's card begin Stripe::Charge.create( :amount => @amount, :currency => 'usd', :customer => customer.id, :description => 'Example charge custom form' ) redirect_to root_path rescue Stripe::CardError => e flash[:error] = e.message redirect_to root_path end current_user.subscribed = true current_user.stripe_id = customer.id current_user.save flash[:success] = "Thank you for subscribing. Your account has been unlocked." end I want to do something like current_user.end_date = (a month from now). Not actually sure how to do this. Then I would check if current_user.end_date is in the future every time the individual logs in. If it's not, I make current_user.subscribed = false. Is this possible, and if so, would you be able to walk me through this because I'm not understanding how to use time too well in rails. Or should I consider doing this as a plan? I wasn't sure because I don't want recurring billing.
