| Preventing ActionView::MissingTemplate in a Backend-only (API) application? Posted: 28 May 2016 04:47 AM PDT My backend API-only application is responding to clients with a RestClient::InternalServerError: 500 Internal Server Error because of the following code ( and there being no templates to render ). def create @project = Project.create(params.require(:project).permit(:name)) @project.update_attributes(key: Devise.friendly_token) respond_to do |format| format.html format.json { render json: @project } end end
Current Solution: Based on the Rails guide to Layouts and Rendering, this can be prevented by using render json: @project Source: http://guides.rubyonrails.org/layouts_and_rendering.html The Ask: But I want to give the client the option of format, so the respond_to block is the more ideal choice.

For the main locale (french), it checked if an article already have the title and if it's the case add an integer (id) at the end but for the second locale (english) it's just generate the slug without checking if article exists (which give me duplicated slugs). Here is my model: class Post < ActiveRecord::Base translates :title, :slug, :content, fallbacks_for_empty_translations: true active_admin_translates :title, :slug, :content, fallbacks_for_empty_translations: true extend FriendlyId friendly_id :slug_candidates, use: [:slugged, :globalize, :finders] private def slug_candidates [:title, [:title, :deduced_id]] # works for main locale but not others end def deduced_id self.class.where(title: title).count + 1 end end

| Multiple database records with one form? Posted: 28 May 2016 01:17 AM PDT I am currently creating a survey where the user is able to choose from four different options for every category. For example: Category 1: [X] Option 1 – [] Option 2 – [] Option 3 – [] Option 4 What I have so far is a table with categories. There I have the names of the categories and some extra info for each category. Additionally I have a survey controller with the form where every category with the options is listed (eaches through the category table entries). The survey table holds the value (option 1, 2, 3 or 4), the category_id as well as the user_id. What I want to achieve now is that it creates multiple database records in the survey table for each category the user fills out basically with one form (?). I had the idea to each through the categories and have the form within the each, the problem is that I will have 25 different forms and every form has its own submit button. I could fiddle around with JS and hide every button expect the last but that seems like a bad idea. What would be the best solution for the problem I am facing? Thanks for any help! |

| How to make JSSOR Slider fit to screen width while keeping the aspect ratio? Posted: 27 May 2016 11:51 PM PDT I'm trying to create an automatic slideshow for my website. I used the JSSOR slider, which works pretty nice. However, it requires you to provide the height and the width of the slider in exact pixels(e.g. 60px or 140px, but not 100% or auto). I want this slider to fit to the screen width, and the height should be scaled while protecting the aspect ratio. I tried to dynamically(in JS) specify the width and height of the slider, but it didn't work. Any suggestions? Here is the html code; (Yes, it is in rails) <div id="slider1_container" style="position: relative; top: 0px; left: 0px; width: 1340px; height: 768px; "> <!-- Slides Container --> <div id="slides_div" u="slides" style="position: absolute; overflow: hidden; left: 0px; top: 0px; width: 1340px; height: 768px; "> <div><%= image_tag "slider2.jpg", class: "landing-row" %></div> <div><%= image_tag "slider3.jpg", class: "landing-row" %></div> <div><%= image_tag "slider4.jpg", class: "landing-row" %></div> <div><%= image_tag "slider5.jpg", class: "landing-row" %></div> <div><%= image_tag "slider6.jpg", class: "landing-row" %></div> <div><%= image_tag "slider7.jpg", class: "landing-row" %></div> </div>
And here is the JS code; jQuery(document).ready(function ($) { var options = { $AutoPlay: true, $SlideDuration: 750, $Idle: 5000, $DragOrientation: 0}; var jssor_slider1 = new $JssorSlider$('slider1_container', options); });

2 approaches of including angular into the project - different result. First one: using asset pipeline Gemfile source 'https://rails-assets.org' gem 'rails-assets-angular' gem 'rails-assets-ng-resource'
application.js //= require angular //= require ng-resource //= require angular-route //= require angular-rails-templates //= require angular-material //= require app //= require_tree ./templates //= require_tree ./controllers //= require_tree ./factories
Error ! angular.self.js?body=1:13643 TypeError: Cannot read property 'then' of undefined at new indexResourceListController

I'not sure whether I need the last file... If you're thinking that it's my connectio setup that's wrong then think no more (about that..). Firstly Resque is not even trying to connect to the right redis. secondly, when I do this: ...on 192.168.2.103: deploy@raspberrypi:~/apps/phototank $ netstat -nlpt | grep 6379 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp 0 0 0.0.0.0:6379 0.0.0.0:* LISTEN - tcp6 0 0 :::6379 :::* LISTEN -

| bundle package with rvm Posted: 27 May 2016 10:46 PM PDT I was reading the book Rails Way. And it discusses running "bundle package". This will store all the .gem files your app uses in vendor/cache. Running bundle install will prefer gems in vendor/cache to gems in other locations. I am using rvm, so I tested this with rvm: rvm gemset create rent_prototype rvm use 2.2.1@rent_prototype gem install rails rvm gemdir /home/viggy/.rvm/gems/ruby-2.2.1@rentme_prototype $ cd /home/viggy/.rvm/gems/ruby-2.2.1@rentme_prototype $ ls -l devise-4.1.1 ls: cannot access devise-4.1.1: No such file or directory
Above I created a gemset with rvm and checked if the devise gem was installed, and it was not since it is not in Gemfile. Now I use bundle package: $ cd - $ bundle package Updating files in vendor/cache * rake-11.1.2.gem * i18n-0.7.0.gem * json-1.8.3.gem ... $ cd vendor/cache $ ls -l devise-4.1.1 ls: cannot access devise-4.1.1: No such file or directory
Of course, no devise gem in vendor/cache either. Then I modify Gemfile and add: gem 'devise'
Then I run bundle install. Now I check where devise was installed: $ bundle show devise /home/viggy/.rvm/gems/ruby-2.2.1@rentme_prototype/gems/devise-4.1.1 $ cd vendor/cache $ ls -l devise-4.1.1 ls: cannot access devise-4.1.1: No such file or directory
So when I install a gem, it installs in the rvm folder. It does not prefer vendor/cache to other locations. If that is the case, what is the purpose of "bundle package" when you are using rvm? |
| PG::UndefindColumn: ERROR on only at action test Posted: 28 May 2016 12:53 AM PDT I'm getting this test error when I run my test by "bundle exec rake test" ERROR["test_unsuccessful_edit", UsersEditTest... ActionView::Template::Error: ActionView::Template::Error: PG::UndefinedColumn: ERROR: column groups_users.group_id does not exist It works fine on development. My test script is below. # test "unsuccessful edit" do # log_in_as(@user) # get edit_user_path(@user) # assert_template 'users/edit' # patch user_path(@user), user: { name: "", # email: "foo@invalid", # password: "foo", # password_confirmation: "bar", # } # assert_template 'users/edit' # end
As you can see, I skipped this test since it apparently nothing wrong in the development environment. The error message is saying "group_id" column does not exist in table "groups_users". But it's actually exist since I've run migration and checked database/behavior by hands. Is there any way to make this test script work? In my models, as you may be guessing, I have below relationships method. • User.rb has_and_belongs_to_many :groups, join_table: :groups_users, dependent: :destroy
• Group.rb has_and_belongs_to_many :user, join_table: :groups_users
And my migration file looks like this: class GroupsUsers < ActiveRecord::Migration def change create_table :groups_users, :id => false do |t| t.integer :group_id t.integer :user_id end end end
There is no validation for these groups values to be present. Please let me know if you have any idea or questions. Thanks, |
| Allow customer to set up his BrainTree Account in My Rails App Posted: 27 May 2016 09:57 PM PDT I am working on this app where i have users and the user can set up payment gateway of his choice from which he wants his (user's) customers to pay while checking out. I have got to implement BrainTree and have no idea how to do it. I have to ask the user to enter his public key, private key and his merchant id in my app and that would set up his payment gateway. I'm not sure i'm very clear and i'm also clueless as to search what exactly and with what to start. Please guide me in the right direction. Also do comment if its not clear. Any sort of help will be appreciated. P.S: Just so that this is clear. My user has his customers and he will enter his braintree account details so that braintree is his payment gateway. |
| Ruby convert hash to histogram in csv Posted: 28 May 2016 04:03 AM PDT I have a hash that looks like this: @histogram = { "Date 1" => [ {"Item 1" => 1}, {"Item 4" => 3} ], "Date 2" => [ {"Item 2" => 7}, {"Item 1" => 2}, {"Item 5" => 1} ], "Date 3" => [ {"Item 4" => 3}, {"Item 2" => 2}, {"Item 8" => 1}, {"Item 1" => 5} ] }
I want to convert that into a day by day histogram CSV file that looks like this: | | Date 1 | Date 2 | Date 3 | | Item 1 | 1 | 2 | 5 | | Item 2 | | 7 | 2 | | Item 4 | 3 | | 3 | | Item 5 | | 1 | | | Item 8 | | | 8 |
What's tripping me up is the fact that the @histogram hash can be totally out of order. The dates (keys) are likely to be in order, but the Items are going to be totally out of order. Moreover, as you can see, the items don't have to be the same across different dates. Where an item is not existent on a particular date, it's quantity in the histogram can be assumed to be 0. |

| CSS works when on static site, but zero height divs when ported to Rails app Posted: 27 May 2016 09:06 PM PDT I've been working on porting a static site I built over to a Rails app for learning + extensibility. The framework is easy enough to understand, asset pipeline is fine, and assets are loading - but for some reason, I'm seeing odd behaviour in my stylesheets between the two. Expected: http://briansdonohue.com <-- static, just HTML/CSS Screencap from rails app Anyway - the stylesheets appear to render the same - except for height. The grid elements are rendering at zero height, rather than filling their parent div like on static. Static CSS - Github Repo: brianshayne/brianshayne.github.io Rails SCSS - Github Repo: brianshayne/brianshayne-rails I'm at a loss as to why it's rendering differently. |
