| Ruby on rails or Laravel Posted: 07 Apr 2016 07:48 AM PDT I am a Web Developer and I am in a middle of a dilemma. I have worked till now with different CMS mostly with Wordpress and Joomla but also Umbraco. Recently i have collaborated i 2 projects with my friend and we have developed them in Laravel framework. Im good at html and css he is on backend. My purpose is to be a Full Stack developer because i feel good also on backend and im trying to make a solution in which framework should i focus to learn more and improve my skills. As i said i have used Laravel and i liked. For Ruby on Rails i have heard and read information that because it is an old and stable MVC framework is better to work with that. I would like to hear a professional opinion in which framework should i focus. Notice that i dont know Ruby. Php i have practices but not a pro. |

| Rails and Puma server - cannot run localhost:3000 - only a white empty page is rendered Posted: 07 Apr 2016 07:20 AM PDT I am using Rails 4.2.6 and Ruby 2.3.0 and Puma 3.3.0 During the last couple days I ran some bundle update and after rails s all browsers for the same URL localhost:3000 are rendering the same blank page. This is consistent for all 6-7 applications I am playing with. However all are working in "production" when deployed to Heroku. Seems to be only a matter related to my dev env. Don't know how to solve this. Any help will be much appreciated. Can't continue development if can't run unit tests on the code I am developing. However all works well when I am using another port. For example when starting the app server with the command rails s -p 3001 or port 3002 I have no problems to run the apps in any browser using the URL localhost:3001 or localhost:3002. What is wrong with my 3000 port or Puma or both? |

| Consult replicating values on digit cpf Posted: 07 Apr 2016 06:25 AM PDT I have a search that when digit a CPF show all results. Ok, but I need that show this way: (Just a person and the quantity of contracts that it has) * My code is in portuguese, sorry Name Registry CPF Contract 1 ---- Show all contracts Contract 2 -------- Contract 3 -----------
But it is currently coming so: (The same values according to the amount of contract) Name Registry CPF Contract 1 ---- Show all contracts Contract 2 -------- Contract 3 ----------- Name Registry CPF Contract 1 ---- Show all contracts Contract 2 -------- Contract 3 ----------- Name Registry CPF Contract 1 ---- Show all contracts Contract 2 -------- Contract 3 -----------
It is replicating values... because contract's number My view is this: <% if params[:pesquisa_func_cpf].present? %> <h4><b>Resultados</b></h4> <% @autorizacoes.each do |autorizacao| %> <table class="table table-condensed"> <tr> <th>Name</th> <td><%= autorizacao.employee.person.name %></td> </tr> <tr> <th>Registry</th> <td><%= autorizacao.employee.registry %></td> </tr> <tr> <th>CPF</th> <td><%= autorizacao.employee.person.cpf %></td> </tr> </table> <hr /> <table class="table table-condensed table-bordered"> <th>Contract number</th> <% @autorizacoes.each do |autorizacao| %> <td><%= autorizacao.number_contract %></td> <% end %> </table> <% end %> <% end%>
In this is my controller: if params[:pesquisa_func_cpf].present? @autorizacoes = Autorizacao.pesquisa_func_cpf(params[:pesquisa_func_cpf]).all I try the .distinct instead of .all, but don't work : ( And my consult (I use oracle), is it: select * from autorizacoes INNER JOIN employers ON employers.id = autorizacoes.employer_id INNER JOIN people ON employers.person_id = people.id WHERE people.cpf LIKE '111.111.111-11'
And it return 3 results, according my example. Please, how make just leave this structure: Name Registry CPF Contract 1 ---- Show all contracts Contract 2 -------- Contract 3 -----------

| Date parsing/converting with AngularJS Posted: 07 Apr 2016 07:29 AM PDT I am working on a personal project where I need to get a date using bootstrap-datepicker convert it to UTC and send it to an API formated as one of the ISO8601 formats ("yyy-mm-dd"). I am using Angular in the front and Rails in the backend API. The problem is that as the application will use multiple locales, the date format sent from date-picker to the angular controller will vary, it can be "dd/mm/yyyy" or "mm/dd/yyyy". How would I be able to make the proper adjustments to send the date to the API independently of the frontend format? |
| Testing Grape api. ActionController::TestCase @controller is nil Posted: 07 Apr 2016 06:11 AM PDT I'm trying to test my grape api and I'm having problems with my test.

| Addressing backbone 304 not modified issue Posted: 07 Apr 2016 05:47 AM PDT I am new to backbone, I am writing a rails app using backbone. When the root page loads backbone renders the page getting results from the api. router.js file var Router = Backbone.Router.extend({ routes: { "": "showActivities", "activity/:id": "showActivity" }, showActivities: function() { var activities = new Activities(); activities.fetch().done(function() { var indexview = new IndexView({ collection: activties }); $('main').html(indexview.render().el); }); }, showActivity: function(id) { } });
Activity collection and model var Activities = Backbone.Collection.extend({ model: Activity, url: '/api/activities' }); var Activity = Backbone.Model.extend({ urlRoot: '/api/activities' });
activities controller class Api::ActivitiesController < ApplicationController def index if params[:location].nil? @activities = Activity.all else @activities = Activity.near(params[:location], 30) end render json: @activites, status: 200 end def create @activity = activity.new @activity.name = params[:name] @activity.save render json: @activities, status: 200 end def show @activity = Activity.find(params[:id]) render json: @activity, status: 200 end end
whenever I load the root page I am not getting any results from the api even though there is data. The network log shows 304 not modified status. I tried changing the fetch by setting cache to false but I am not getting any data from api. Is there anything I am doing wrong? Your feedback is much appreciated. Please let me know if you need more details. |

| Why is Spree API tests complaining about missing templates for spree/api/shipments/show, spree/api/base/show Posted: 07 Apr 2016 05:53 AM PDT I'm making some tweaks to the Shipping API. To back this by test I've copied solidus/api/spec/controllers/spree/api/shipments_controller_spec.rb into MY_RAILS_APP/spec/controllers/spree/api I've also copied the API views into my app. cp -r solidus/api/app/views/spree/api/* app/views/spree/api/
So this is what's happening when I run the tests: [93, 102] in /Users/martins/Work/Hoome/spec/controllers/spree/api/shipments_controller_spec.rb 93: 94: it "can make a shipment ready", focus: true do 95: allow_any_instance_of(Spree::Order).to receive_messages(paid?: true, complete?: true) 96: api_put :ready 97: debugger => 98: expect(json_response).to have_attributes(attributes) 99: expect(json_response["state"]).to eq("ready") 100: expect(shipment.reload.state).to eq("ready") 101: end 102: (byebug) (byebug) json_response {"exception"=>"Missing template spree/api/shipments/show, spree/api/base/show with {:locale=>[:en], :formats=>[:json], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :rabl, :jbuilder], :versions=>[]}.

/Users/martins/Work/Hoome/app/views/spree/api/shipments/show.v1.rabl is present, but I could not find any templates for spree/api/base/show. (If it is that the error message is complaining about).
Questions - What should I do to get my test running?
- I would prefer not to copy views from the gem into my Rails app, if that is possible. Any ideas on how to do that?

| variable in .click function not reset on second click Posted: 07 Apr 2016 07:05 AM PDT I've a jQuery function in rails which sets variable values from ajax and passes them to Pick A Date, every time an input is clicked. The variables are only setting once in the javascript, and not every time an input is clicked. PickADate's windows open correctly when any input is clicked -> but the values are just kept at the initial values for page load. The variables correctly update in the #dates-array element's html, using ajax. I notice if I drop an alert within that function, it also only fires once. The site is using Turbolinks -> hence .on("page:change" $(document).on("click", ".pick-a-date input",function() { var date_options; var time_options; date_options = $("#dates-array").data("pick-a-date-options"); time_options = $("#times-array").data("pick-a-time-options"); date_options = dateStringsToDateObjects(date_options); time_options = dateStringsToDateObjects(time_options); PICKERS.collection_date = $('#order_collection_time_date.datepicker') .pickadate(date_options.collection_date_options) .pickadate('picker'); PICKERS.collection_time = $('#order_collection_time_time.timepicker') .pickatime(time_options.collection_time_options) .pickatime('picker'); PICKERS.delivery_date = $('#order_delivery_time_date.datepicker') .pickadate(date_options.delivery_date_options) .pickadate('picker'); PICKERS.delivery_time = $('#order_delivery_time_time.timepicker') .pickatime(time_options.delivery_time_options) .pickatime('picker'); PICKERS.collection_date.on('close', collectionDateCallback); PICKERS.collection_time.on('close', collectionTimeCallback); PICKERS.delivery_date.on('close', deliveryDateCallback); PICKERS.delivery_time.on('close', deliveryTimeCallback); return; });
If anyone can see where I'm going wrong, it would be greatly appreciated. UPDATE: If I take out the two pick_a_date functions, the variables are set correctly. The problem only occurs when they are in the function. PICKERS.collection_date = $('#order_collection_time_date.datepicker') .pickadate(date_options.collection_date_options) .pickadate('picker'); PICKERS.delivery_date = $('#order_delivery_time_date.datepicker') .pickadate(date_options.delivery_date_options) .pickadate('picker');

| Adding User Input to a hash? Ruby Posted: 07 Apr 2016 07:21 AM PDT I am trying to create some simple programs as trying to learn Ruby and then move on to rails, I am just playing about to try and get used to the flow of how different types of code work variables, loops etc. I am trying to create a simple book system were I already have 3 books in my hash and then I want to list the books already in the library in the console and then I want to be able to add new books and then also loop through and display the new list to the console. require 'rubygems' class GetDetailsFromUser books = { Eagle_Eye: 1, Eage_Eye1: 2, Eagle_Eye2: 3 } books.each do |i| puts i end while true add = gets.chomp break if add.empty? books << add end puts 'New list is below' books.each do |i| puts i end end
Were am I going wrong? I manage to print out the hash to the console, however, I get an error message undefined method '<<' for {:Eagle_Eye=>1,...
Why is the method undefined? books << add? This should add a new book to the book hash table? |
| Results of infinte scroll are prepending instead of appending Posted: 07 Apr 2016 05:01 AM PDT I'm using the will_paginate gem to paginate a list of users on my user index page. This pagination is working properly, so that when I click for the users on page 2, I'm taken to those users. However, I implemented 'infinite scroll' on another part of this site and it worked beautifully, so I wanted to do the same with the users index page. When I scroll down, I want the new users to appear at the bottom of the page 1 user table. Currently the issue I'm running into though is the users aren't being 'appended' at the end of the page 1 users, they're being 'pre-pended' above the page 1 users. index.html.erb - users
<hr> <div class="container"> <div class="row"> <div class="col-lg-12"> <div class="main-box no-header clearfix"> <div class="main-box-body clearfix"> <div class="table-responsive"> <table class="table user-list"> <thead> <tr> <th><span>User</span></th> <th><span>Friends</span></th> <th class="text-center"><span>Status</span></th> </tr> </thead> <div id="all-users" > <%= render @users %> </div> <div id="infinite-scrolling"> <%= will_paginate %> </div> </table> </div> </div> </div> </div> </div> </div>
_user.html.erb
<tbody> <% unless user == current_user %> <tr> <td> <%= image_tag user.gravatar_url default: "retro" %> <%= link_to user.name, user_path(user) %> </td> <td><%= pluralize(user.friends.count, "Friend") %></td> <td class="text-center"> <div id="friend-form"> <%= render partial: 'friendships/friendships_status', locals: {user: user} %> </div> </td> </tr> <% end %> </tbody>
Relevant CSS: @import "bootstrap-sprockets"; @import "bootstrap"; @import "font-awesome"; ..... .user-list tbody td .user-subhead { font-size: 0.875em; font-style: italic; } .user-list tbody td .user-link { display: block; font-size: 1.25em; padding-top: 3px; margin-left: 60px; } a { color: #3498db; outline: none!important; } .user-list tbody td>img { position: relative; max-width: 50px; float: left; margin-right: 15px; } .table thead tr th { text-transform: uppercase; font-size: 0.875em; } .table thead tr th { border-bottom: 2px solid #e7ebee; } .table tbody tr td:first-child { font-size: 1.125em; font-weight: 300; } .table tbody tr td { font-size: 0.875em; vertical-align: middle; border-top: 1px solid #e7ebee; padding: 12px 8px; }
In case it's helpful: class UsersController < ApplicationController def index @users = User.all.paginate(page: params[:page], per_page: 15) end end
I believe this issue relates to my CSS. When I look at the 'pre-pended' page 2 results, it appears they're not part of the table user-list class but are rather identified by their all-users id tag. |
| Rails validate model attribute based on value of another attribute Posted: 07 Apr 2016 05:30 AM PDT I have a rails app with User model which has state and city attributes.
I am using a gem to get the list of cities of a given state and country.
I want that while signing up if the city selected by user is not in the list of cities for the state selected by user then dont allow signup and show error. validates :state, presence: true, inclusion: { in: CS.states(:in).keys.collect{|x| x.to_s } } validates :city, presence: true, inclusion: { in: CS.cities((:state).to_sym, :in) } I wrote this code in user.rb model but its not working.
:state should refer to the value submitted by user for 'state' attribute but i don't think that's working here. I want to pass the value of state given by user to the function CS.cities(). How do I fix this? |
| Nested attributes validations fails in parent association Posted: 07 Apr 2016 05:18 AM PDT If you want to go straight to the question, just go to the last paragraph. A Pack has many items included, Item is polymorphic and one of the linked tables is Access (so Access is an Item that can be added to the Pack) Here you are the models and controller. class Pack < ActiveRecord::Base has_many :pack_items, dependent: :destroy has_many :items_included, through: :pack_items, source: :item accepts_nested_attributes_for :pack_items, allow_destroy: true validate :valid_max_value, if: :infinite_item? end class Item < ActiveRecord::Base has_many :pack_items, dependent: :restrict_with_error has_many :packs, through: :pack_items end class Access < ActiveRecord::Base has_one :item, as: :itemable, dependent: :destroy has_one :entitlement, as: :entitlementable, dependent: :destroy accepts_nested_attributes_for :item, allow_destroy: true accepts_nested_attributes_for :entitlement, allow_destroy: true validate :valid_max_value, if: :infinite? private def infinite? entitlement.infinite end end class PacksController < BaseController def update @pack = Pack.find(params[:id]) if @pack.update(permitted_params) ... end end private def permitted_params params.require(:pack).permit(item_attributes: [:id, :name, :max_purchasable], pack_items_attributes: [:id, :item_id, :amount, :_destroy]) end end
There is an importan validation in pack "valid_max_value. If a pack has an infinite Access inside, the max_value of the Pack should never be higher than 1. It works perfectly when I create a pack and I add some Accesses, but the problem is this: - I have a Pack with two Items. An Access that's infinite and a common Access(not infinite). So the Pack's max_value should be 1 because it has an infinite Access inside.
- Now I edit that Pack and I delete the infinite Access, so now I can select a higher max_value, 5 in example, because the pack doesn't have an Access with restriction inside.
- When I click update there is a rollback because the valid_max_value validation runs before the deletion of the infinite Access, so it says the max_value is invalid because the validation depends on a child field.
In short, my question is: How can I delete the nested items before run the parent validation? |
| Rendering a file/template with layout outside of controller with Rails 4 Posted: 07 Apr 2016 05:38 AM PDT Currently I am rendering a view in Rails 4 outside of a Controller with this code: av = ActionView::Base.new(ActionController::Base.view_paths, {}, ActionController::Base.new) av.config = Rails.application.config.action_controller av.class_eval do include ApplicationHelper end html = av.render( file: '/users/index', locals: {} )
How can I render the view inside of a layout? The following does not work: html = av.render( file: '/users/index', locals: {} layout: 'layouts/application' )
Thanks! |

| Hero with gradient using ::before not working correctly Posted: 07 Apr 2016 05:30 AM PDT I am trying to have a hero image page with a gradient using the ::before selector. The effect is working but there is one issue; it is out position so I want it to fit over the .hero div but there are some offset. I only could get this working using the absolute position which is not the ideal for this. .hero1 { background: image-url('noche-en-santo-domingo.jpg') no-repeat fixed center; background-size: cover; height: 89vh; &::before { content: ''; position: absolute; top: 6vw; right: 0; bottom: 0; left: 0; background-image: linear-gradient(to bottom right,#002f4b,#dc4225); opacity: .4; } .intro { padding: 3rem; position: relative; top: 50%; transform: translateY(-50%); } }
<section id="hero" class="hero1"> <div class="row intro"> <div class="small-centered medium-uncentered medium-6 large-7 columns"> <h1>We are caribbean developers</h1> <p><strong>We Help the People make Better Software and we are young people with bilingual skills and professionalism, specializing in various areas of Information Technology (IT)</strong></p> </div> <div class="small-centered medium-uncentered medium-6 large-5 columns"> <div class="tech-img"></div> </div> </div> </section>

| Rails routes constraint - unicode regex not matching Posted: 07 Apr 2016 04:42 AM PDT So I have a route with a constraint that matches paths such as the following: /jobs-in-London get ':id' => 'search#show', :constraints => { :id => /jobs-in-[A-Z].*/ }
This works great, but I need to match to locations written in other character sets, such as Japanese. I am happy for the "jobs-in-" to remain in english, since the valid urls are generated from a list of locations uploaded by the user. This means I would be expecting to match /jobs-in-東京, which would then search in Tokyo once it hit the controller. Geolocation is done later, and works without translation. I just need to get the request to the right controller. I have tried this: get ':id' => 'search#show', :constraints => { :id => /jobs-in-\p{L}*/ }
which I constructed using Rubular, and it appears to match correctly as seen here. I am aware this doesn't have the capital letter constraint, but that doesn't matter as some languages don't seem to have true capital letters anyway. However the routes don't match it, and instead spit it out to the wildcard catch all at the bottom. Am I falling foul of how Rails implements regex for routes? Does it not support the unicode selectors? I cannot have this: get ':id' => 'search#show', :constraints => { :id => /jobs-in-.*/ }
as this matches /jobs-in-$£@ which is undesired, I want to constrain it to "letter" characters. |
| Find record which doesn't have any associated records with a specific value Posted: 07 Apr 2016 05:49 AM PDT I have a couple of models: User and UserTags A User has_many UserTags A UserTag belongs_to User
I am trying to find all the Users which don't have a UserTag with name 'recorded' (so I also want users which don't have any tags at all). Given a users relation, I have this: users.joins("LEFT OUTER JOIN user_tags ON user_tags.user_id = users.id AND user_tags.name = 'recorded'"). where(user_tags: { id: nil })
Is there any other better or more Railsy way of doing this? |
| Enable LeadHistory/ Lead field tracking via salesforce api Posted: 07 Apr 2016 04:25 AM PDT I am using restforce gem for salesforce apis. I am able to do operations i wanted to be performed with it. I want to fetch the lead changes which I can get via client.query('select Id from LeadHistory')
But couldn't find the way to enable the lead history tracking by api. |
| Testing Views in Rspec , undefined method collect Posted: 07 Apr 2016 05:33 AM PDT I got this following error while i am testing views in Rspec. 1) problems/new renders new problem form Failure/Error: <div class="col-md-8 col-sm-8"> <%= f.select :approval_status, options_for_select(@approval_statuses.collect { |as| [as[0].humanize, as[0]] }, selected: @problem.approval_status), {}, class: "form-control" %> </div> ActionView::Template::Error: undefined method `collect' for nil:NilClass

| Cocoon fields rendering wrong ID in deep nesting Posted: 07 Apr 2016 04:24 AM PDT I have a rather complicated form that I'm putting together with cocoon and am having trouble getting the correct id for some of my fields to properly reflect the nesting. In summary, I have three different instances of nested fields via cocoon in one deeply nested partial. One of those fields renders the id perfectly fine (all nested models included). The other two leave out the highest level model from the id. The models are as follows: You need only be concerned with four: Stock, Stockholder, EntityJoin, Person and Org. Stock has_many :stockholders
class Stockholder < ActiveRecord::Base belongs_to :stock belongs_to :entity, polymorphic: true has_many :entity_joins, as: :holder accepts_nested_attributes_for :entity_joins, allow_destroy: true has_many :people, through: :entity_joins, source: :entity, source_type: 'Person' accepts_nested_attributes_for :people, allow_destroy: true has_many :orgs, through: :entity_joins, source: :entity, source_type: 'Org' accepts_nested_attributes_for :orgs, allow_destroy: true
I have a form for Stock, which allows me to dynamically create Stockholders. For each stockholder, a user can either manually add an EntityJoin (which joins an existing Person or Org to the Stockholder) or the user can create a new Person or Org. So nested within Stockholder (which itself is nested in a simple_form_for Stock), I have the following partial: <div class="holder_fields holderStop"> <div class="holderTextEntry"> <span> <input class="typeahead"> <span class="newEntityButtons"> <span class="prefix">New</span> <span class="addpersonbutton newHolder newPerson">Person</span> <span class="addorgbutton newHolder newOrg">Company</span> </span> </span> </div> <div class="entityBoxes"> </div> <div class="entitiesTechincal"> <label>From Existing Contacts</label> <div class="existing_contacts new_fields"> <%= f.simple_fields_for :entity_joins do |ejoin| %> <%= render 'shared_equity/entity_join_fields', f:ejoin %> <% end %> </div> <div> <%= link_to_add_association 'Add Existing Contact', f, :entity_joins, partial: 'shared_equity/entity_join_fields', :"data-association-insertion-node" => "div.existing_contacts", :"data-association-insertion-method" => "append", class: "btn btn-default add-button" %> </div> <label>From Existing Contacts</label> <div class="new_person new_fields"> <div> <%= link_to_add_association "Create New Person", f, :people, partial: 'shared_equity/person_fields', class: "btn btn-default add-button" %> </div> </div> <label>From Existing Contacts</label> <div class="new_fields new_org"> <div> <%= link_to_add_association "Create New Company", f, :orgs, partial: 'shared_equity/org_fields', class: "btn btn-default add-button" %> </div> </div> </div> </div>
The partial contains three applications of cocoon as described above. You may notice that I only have simple_fields for :entity_joins and not for the other two. This is done intentionally as it suits my specific application. The problem: While my entity_joins fields render just fine, with an id of stock_stockholders_attributes_0_entity_joins_attributes_0_..., my :people and :orgs fields only render with an id of stockholder_people_attributes_.... (The key concern being the lack of any reference to stock_ at the beginning.) As you can imagine, this causes major trouble while saving it, as the nesting is off. What might be causing this? Many thanks in advance for any help. I realize this is somewhat complicated. |
