| The gem wkhtmltopdf and pdfkit in a Rails app on Heroku produces an error Posted: 06 Sep 2016 08:08 AM PDT I have a rails 3.2 app on heroku and these 2 gems: ruby "2.2.4" gem 'rails', '3.2.16' # ....... gem 'wkhtmltopdf-binary-11' gem 'pdfkit'
However, when I'm trying to generate pdf, I get the following errors: QSslSocket: cannot resolve SSLv2_client_method QPixmap: Cannot create a QPixmap when no GUI is being used
Obviously, I can't install a library or update it on heroku to fix the errors. How to fix them? And the same kind of error I have locally, but I'm on Arch. |
| Rails 4 Error: ActiveRecord::RecordNotFound Couldn't find 'id'= Posted: 06 Sep 2016 08:04 AM PDT
Hey,
I'm fairly new to rails and into coding my first app. Just can't figure out how to target a user the current_user favorited (Three models: User, Tool, FavoriteUser). Controller (Tools) def index @favorites = current_user.favorites.order("created_at DESC") @userfavorites = current_user.userfavorites.order("created_at DESC") @tools = Tool.where(user_id: current_user).order("created_at DESC") @user = FavoriteUser.find(params[:c_user_id]).user_id @cuser = current_user end
Index View (Tools) %h2 My Favorite Users - @userfavorites.each do |user| = image_tag gravatar_for @user if @user.use_gravatar == true = image_tag @user.avatar_filename.url if @user.use_gravatar == false %h2= link_to @user.username, @user %p= link_to "Favorite", @userfavorite_user_path(user, type: "favorite"), method: :get %p= link_to "Unfavorite", @userfavorite_user_path(user, type: "unfavorite"), method: :get
If I run this in my browser it appears following error: ActiveRecord::RecordNotFound in ToolsController#index Couldn't find FavoriteUser with 'id'=
I simply can't figure it out.
Thanks in advance for your help! |
| Rails Cookies to manipulate database entries Posted: 06 Sep 2016 07:51 AM PDT I am trying to create a rails app and I have a database consisting of author and a quotation by that author. Now different users can choose to destroy or kill quotations from the database however it must only be deleted for that particular user i.e other users should still be able to see quotes that they didn't delete even if another user did. I know that I would need to implement cookies but other than that I am unsure how to proceed. Can anyone point me to a tutorial or give me some pointers to get started on this complex task? Thank you PS: New to rails!!! |
| Turbolinks loads Javascript multiple times Posted: 06 Sep 2016 07:50 AM PDT I'm using Turbolinks 2.5.3 and I have a script tag at the bottom of the home page. <script> $(document).ready(function() { alert('hello'); }); </script>
For every page on the site, I run the following JS: Turbolinks.pagesCached(0);
If I visit the home page, the alert appears once. If I press the back button then forward button on my browser the home page will load, and now two alerts appear. If I repeat this process again, three alerts will appear. Here's my question: Why is Turbolinks caching the page when I explicitly told it not to. Does it have to do with Turbolinks transforming the document ready event listener? How do I fix this so it only loads once every time? |
| EER diagram for a Rails app Posted: 06 Sep 2016 07:48 AM PDT I have a rails app. I am trying to reverse engineer an EER diagram with a few selected tables. For example, these 2 tables: create_table "fee_parameters", force: :cascade do |t| t.integer "fee_type_id", limit: 4 t.string "name", limit: 255 t.string "value", limit: 255 t.string "parameter_type", limit: 255 t.datetime "created_at", null: false t.datetime "updated_at", null: false end create_table "fee_rules", force: :cascade do |t| t.integer "fee_suite_id", limit: 4 t.integer "fee_parameter_id", limit: 4 t.string "name", limit: 255 t.float "multiplier", limit: 24 t.float "addend", limit: 24 t.datetime "created_at", null: false t.datetime "updated_at", null: false end
In Workbench, when I click on the 1:1 icon and select these 2 tables then inside the fee_rules table is generated a fee_parameters_id. But I already have that foreign key. It's called fee_parameter_id. How do I let Workbench know this is the case? |

| Creating some class during tests (STI) Posted: 06 Sep 2016 07:53 AM PDT I have a class Gate < ActiveRecord::Base self.inheritance_column = :kindof # some methods end # and derived MoneyHaters < Gate # some overloaded methods end
with type column :kindof for STI. Durning tests I want to create a 2-3 childs. Mainly because each derived class must be unique in the app. Like that: factory :gate do before(:create) do gate_name = FFaker::Company.name.gsub( /\s+/,'' ) gate_class_name = gate_name.singularize.classify end name { gate_name } # I want that next class will be declared in App namespace, like all others. gate_class = Class.new(Gate) do def comission_in(amount) amount * 0.01 + 5 end def comission_out(amount) amount * 0.02 + 5 end end Object.const_set( gate_class_name, gate_class ) type { gate_class_name } country { FFaker::Address.country_code } end
Code gave me error when ran with rspec in line "Object.const_set" TypeError: #<FactoryGirl::Declaration::Implicit:0x00000006a1af30 @name=:gate_class_name, @ignored=false, @factory=#<FactoryGirl::Definition:0x00000006ed6df8 @declarations=#<FactoryGirl::DeclarationList:0x00000006ed6dd0 @declarations=[#<FactoryGirl::Declaration::Dynamic:0x00000006ed6998 @name=:name, @ignored=false, @block=#<Proc:0x00000006ed69c0@[skipped]>>, #<FactoryGirl::Declaration::Implicit:0x00000006a1af30 ...>], @name=:gate, @overridable=false>, @callbacks=[#<FactoryGirl::Callback:0x00000006ed6a38 @name=:before_create, @block=#<Proc:0x00000006ed6ba0@[skipped]>>], @defined_traits=#<Set: {}>, @to_create=nil, @base_traits=[], @additional_traits=[], @constructor=nil, @attributes=nil, @compiled=false>> is not a symbol nor a string
but works ok in rails console Usually I call FactoryGirl factories for creating objects, but, if that is impossible - I wonder for any other method to do that. Any help is very much appreciate. |

| Reset DB from Controller/Helper, Ruby on Rails Posted: 06 Sep 2016 07:58 AM PDT I've created a demo of my program. The demo is used to present the program to the customers. Before each presentation I want to reset the db, and insert certain data, the actions that I have to do are: rake db:drop rake db:setup rake db:seed:demo
But they are not always me to present it and others do not use the console, so I wanted to put in the settings page the ability to reset via a button. I tried in this way: module SettingsHelper require 'rake' def reset Rake::Task[db:drop].invoke Rake::Task[db:setup].invoke Rake::Task[db:seeds:demo].invoke end end
I put in the form: <%=button_to "Reset", reset, class:"btn red" %>
But I can not drop the database with the active server ... how can I do? |

| Rspec feature test. Page content doesn't differ among ordinary user and admin Posted: 06 Sep 2016 06:02 AM PDT I'm new to testing. I use rspec-rails, factory_girl_rails and capybara to test Rails 5 app. For authentication I have devise. My User model has additional field admin. By default admin is false. But first registered user becomes an administrator (user.admin = true). Now when I do user = create(:user) in my test it creates an 'ordinary' user (user.admin = false) But if I puts page.body I can see content which should not be rendered for an ordinary user. Here is my template: %menu %ul - if user_signed_in? %li Hey, #{current_user.name} %li= link_to "Edit Profile", edit_user_registration_path - if current_user.admin %li= link_to "Today's Orders", todays_orders_path %li= link_to "Registered Users", users_path %li= link_to "Add Dish", new_dish_path %li= link_to "Sign Out", destroy_user_session_path
Feature test's snippet: require 'rails_helper' require_relative '../support/authentication' feature 'page content' do let(:user) { create(:user) } scenario 'show page content' do authentication = Authentication.new user authentication.sign_in puts page.body end end
That's what puts return: <menu> <ul> <li> Hey, Test User </li> <li><a href="/users/edit">Edit Profile</a></li> <li><a href="/todays_orders">Today's Orders</a></li> <li><a href="/users">Registered Users</a></li> <li><a href="/dishes/new">Add Dish</a></li> <li><a href="/users/sign_out">Sign Out</a></li> </ul> </menu>
I suppose current_user.admin is ignored or something. But how to make it work properly? |

| Scroll event doesn't work unless the page is reloaded Posted: 06 Sep 2016 05:50 AM PDT I'm looking to set a "scroll up" button using JQuery for my rails application. Here's the JQuery script: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> <script type="text/javascript"> $(function() { $(window).scroll(function() { if($(this).scrollTop() > 300) { $('#toTop').fadeIn(); } else { $('#toTop').fadeOut(); } }); $('#toTop').click(function() { $('body,html').animate({scrollTop:0},300); }); }); </script>
Here's CSS for the button: #toTop { width:100px; text-align:center; padding:5px; position:fixed; bottom:5px; left:50%; cursor:pointer; display:none; color:#333; font-size:20px; &:hover { color: #8B0000; } }
When I open a new page, say localhost:3000/signup, the button scrolls up just fine. But if I click on another page, the scroll event doesn't happen. Thus, the button works properly either if I reload the page or open a new one in another tab. What might cause the problem? |

| Globalize gem: how to keep track of translations? Posted: 06 Sep 2016 04:12 AM PDT I want to translate some models in my Rails app using Globalize gem. This seems pretty easy, but I wonder how it's best to keep track of changed texts? So that I don't forget to update all other translations after I changed one of them? Is there some feature for this already built in? So I can see which fields of my model have changed in the meantime compared to some translation, and then I can do the translations and fix them as done? Also, when I just fix a typo, I don't want the translation to be seen as "changed". |

| Ruby regex for domains Posted: 06 Sep 2016 05:06 AM PDT I am looking for a domain validator regex which validates domain. Preferably I want to use some inbuilt regex using URI::Regexp. Domain scheme and protocol are optional. It should validate all domains of type abc.com, abc.cm, ab.com/aka/jaka, abc.aio.com
It should invalidate domains of type abc, abc. jska |
| ember uploader authentication help please Posted: 06 Sep 2016 05:30 AM PDT I am trying to upload an image to a rails API from an ember app. I have installed the ember uploader addon and my URL is correct (works perfectly through postman), but I am having problems with authentication. The app itself is set up with devise and the routes all have authenticatedRouteMixin and the adaptors have the dataAdaptorMixin which automatically take care of the authentication. I am struggling to inject authentication into the the call to the API. Any help would be appreciated. My call to the API currently looks like this. An extra argument can go at (files[0],{extraArgument}) but not sure if this is even where I should be putting authentication details or how to access them. export default EmberUploader.FileField.extend({ filesDidChange: function(files) { const uploader = EmberUploader.Uploader.create({ url: this.get('url'), method: 'PUT', }); if (!Ember.isEmpty(files)) { data with the upload uploader.upload(files[0]); } } });
PS. An additional problem I have is that the url needs to be supplied however I need to be supplying the id of the models so it knows where to go, any suggestions on how to dynamically make the URL would also be appreciated |

| Heroku not installing private gem locally Posted: 06 Sep 2016 05:45 AM PDT I have an issue with installing a private gem on heroku. I have managed to install it once, with the oauth token, and the deploy goes just as it should. The Gemfile line goes like this: gem 'personal_gem', "0.0.3", git: "https://TOKEN:x-oauth-basic@github.com/personal_gem.git", branch: :master
It all goes as planned the first time around. I go back to my project all happy, make a few changes and then deploy again. And I get this amazing message: Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin -j4 --deployment remote: /tmp/build_b69276ed81314bd83fe154e89deceb82/vendor/ruby-2.2.4/lib/ruby/2.2.0/rubygems/dependency.rb:315:in 'to_specs': Could not find 'personal_gem' (>= 0) among 159 total gem(s) (Gem::LoadError)`
Boom. I believe I've tried it all. Bumping up the gem version, all the "git", "github" combinations in the Gemfile I could think of. Heroku gem list does NOT list the gem! Heroku bundle install DOES list the gem. On my machine, installations go just fine. There are no local gem installations of this gem to conflict with the one I'm pushing online, it shows the github link properly. The most bizarre thing is that the first install goes as it should. Also, if I change the ruby version and push, it also goes just fine. But not on subsequent pushes on the same ruby version. I'm under impression that for some reason the gem isn't installed on heroku. However, the site + gem functionality work as intended online. This is some X-Files stuff here, and any help/pointers are really appreciated! |
| sanitize and raw still showing html tags, Slim Posted: 06 Sep 2016 05:37 AM PDT I have a comment data which contains html text, and I want to show the html renders without any tags inside. I'm working with RoR and slim. I tried sanitize, raw and html_safe. but all of them gave me the same result. they removed some html but I still see html tags. data before using them: <img alt="User-added image" src="https://rrrrr;amp;feoid=00N2400000H7Rxb&amp;refid=0EM7E0000004FgN" style="height: 333px; width: 500px;"></img><br><br>Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam
data after using them: = raw resource.comments = sanitize resource.comments = strip_tags "'#{resource.comments}'" = ActionView::Base.full_sanitizer.sanitize(resource.comments)
or def formatted_comments h.sanitize(comments, :tags => [], :attributes => []) end = formatted_comments
result: <img alt="User-added image" src="https://rrrrr;feoid=00N2400000H7Rxb&refid=0EM7E0000004FgN" style="height: 333px; width: 500px;"></img><br><br>Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

Update: I noticed that the rendered html tag contains the following. " my result of html tags here " = $0 trying to remove it manually, all html was rendered! |

| Rails gem for shared static pages Posted: 06 Sep 2016 03:18 AM PDT I have a core gem which is used by two applications.
