| Highcharts Tooltip not rendering properly if it has material icons Posted: 02 Jan 2017 07:39 AM PST In my rails application I have a graph with icons generated with Highcharts. The icons are Google Material design icons that I get through a material-icons gem. https://github.com/Angelmmiguel/material_icons. I want to do 2 things with the icons: Instead of numeric labels I want smileys. This I got working yAxis: { max: 5, min: 1, labels: { formatter: function () { if (this.value == 1) { return '<i class="material-icons">sentiment_very_dissatisfied</i>' } if (this.value == 2) { return '<i class="materialicons">sentiment_dissatisfied</i>' } if (this.value == 3) { return '<i class="material-icons" height="5px">sentiment_neutral</i>' } if (this.value == 4) { return '<i class="material-icons">sentiment_satisfied</i>' } if (this.value == 5) { return '<i class="material-icons">sentiment_very_satisfied</i>' } else { return this.value } } } },
Instead of numeric values in the tooltip I want smileys. This is where it goes wrong. tooltip: { formatter: function () { var date = Highcharts.dateFormat('%d-%m-%y %H:%M', new Date(this.x)); var getIcon = function (y) { if (y == 1) { return '<i class="material-icons">sentiment_very_dissatisfied</i>' } if (y == 2) { return '<i class="material-icons">sentiment_dissatisfied</i>' } if (y == 3) { return '<i class="material-icons">sentiment_neutral</i>' } if (y == 4) { return '<i class="material-icons">sentiment_satisfied</i>' } if (y == 5) { return '<i class="material-icons">sentiment_very_satisfied</i>' } else { return y } }; var icon = getIcon(this.y); console.log(date); return '<b>' + this.series.name + '</b><br/>' + date + ' : ' + icon; },
I have to parse the date because it is a JavaScript epoch time(milliseconds). Without + icon the date is shown. If I add + icon it doesn't work and the date will not correctly render. What I noticed is that the icon is higher than the line itself. So I think this is a CSS problem, but I don't know how to fix it.

| Update Attributes of a Specific Record Posted: 02 Jan 2017 06:09 AM PST Let's say I have a bunch of cards listed on my wall show action. When you interact with a card (click it for example), I want to update that card's attributes. I'm currently doing this by getting the card's attributes with Javascript, adding them to a card form and submitting the form remotely. I have the card's ID, but how do I tell the form which card I want to update? What should the form and controller update action look like? This is what I have so far Form <%= form_for(@card, remote: true) do |f| %> <%= f.text_field :list_id %> <%= f.text_field :order %> <% end %>
Controller def update @card = Card.find(params[:id]) if @card.update_attributes(shared_params) redirect_to edit_card_path(@card, format: :html) else render :edit end end

| bootstrap star rating and dynamic tabs conflict Posted: 02 Jan 2017 06:26 AM PST In my Rails application I am using bootstrap dynamic tabs which was working fine but when I included the js of bootstrap-star-rating from https://github.com/kartik-v/bootstrap-star-rating/blob/master/js/star-rating.js it stopped working. This is my Rails application.js file //= require jquery //= require jquery_ujs //= require jquery-ui //= require bootstrap.min //= require bootstrap-slider //= require timepicker.min //= require modernizr.custom //= require star-rating //= require page
And this is the code for showing bootstrap stars in page.js file: $(document).ready(function () { $("a[href='#overview']").click(function(){ $(this).parent('li').addClass('active') $("[data-toggle=tab]").parent('li').removeClass('active') $(".tab-pane").addClass('active in') }) $('.star-rating').rating({min: 0,max: 5,step: 1,size: 'xs',showClear: false,showCaption: false}); $('.star-rating').on('rating.change', function() { rating = $(this).val() get_id = $(this).attr('id') $('input#'+get_id+'_rating').val(rating) });
And this is the code for bootstrap tabs. %ul.nav.nav-tabs %li.active %a{"data-toggle" => "tab",:href => "#overview"} Overview %li %a{"data-toggle" => "tab", :href => "#offers"} Offers %li %a{"data-toggle" => "tab", :href => "#services"} Services %li %a{"data-toggle" => "tab", :href => "#reviews"} Reviews .tab-content #overview.tab-pane.active.fade.in %h3.hidden-heading Overview %p= @business["description"] #offers.tab-pane.active.fade.in

| Link to specific ajax tab in rails Posted: 02 Jan 2017 07:37 AM PST I have a question that I have not found a answer for yet. In my Rails 4 application I use ajax tabs. Here is an example for the code setup. show.html.erb <div id="ajaxtabs"> <ul class="nav nav-tabs"> <li><%= link_to 'Members', some_member_path, :remote => true %></li> <li><%= link_to 'Hosts', some_host_path, :remote => true %></li> </ul> </div> <div class="tab-content"> <div id="tab-display"></div> </div>
members.js.erb $("#tab-display").html("<%= escape_javascript (render partial: 'members') %>");
_members.html.erb "This is the partial displayed when the members tab is clicked"
Everything work beautifully, but there is one feature that I would like to get to work, and that is the ability to link to a specific tab. For example if I would like to link to the members tab I could type the url maybe like? sitename.com/groups/#members-tab |
| unpermitted parameter simple_form Posted: 02 Jan 2017 06:17 AM PST I am trying to create a nested form with Simple_fields in ruby 4. However, every time i try to enter data into the form i get a unpermitted parameter error in the serverconsole after trying to submit. I already tried the sollutions found in the simple_form wiki and did some testing, but that doesn't seem to work.

| ruby map find_each can't add to array Posted: 02 Jan 2017 04:44 AM PST I have 2 Models: Document and Keywords. They are habtm in relation to each other and they both accepts_nested_attributes_for each other so I can create a nested form. That works well. So in params, I have "document"=>{"book_id"=>"1", "keywords"=>{"keywords"=>"term, administration, witness "}, ...
In the controller I put the keywords in a separate array like this : q = params[:document][:keywords].fetch(:keywords).split(",")
This works well too. What I now need to do, is get the keywords ids and put them in an array. Each element of that array will populate the join table. I've tried this : a = Array.new q.each do |var| id = Keyword.select(:id).find_by keyword: var a << id id end
But, this only answers [#<Keyword id: 496>, nil, nil], although the server log shows that all 3 SQL requests are executed and they are correct. I have also tried this : a = Array.new q.map do |e| Keyword.where(motcle: e).select(:id).find_each do |wrd| a << wrd.id end end
Then again, this only return the FIRST id of the keyword, although the server log shows that all 3 SQL requests are executed. What I'm trying to get is a = [496, 367, 2398] So I have 2 questions : 1/ Why are the ids not added to the array, despite the server executing all SQL requests ? 2/ How to write in rails a request would be SELECT "motclefs"."id" FROM "motclefs" WHERE "motclefs"."motcle" in ('déchéances','comtesse') ORDER BY "motclefs"."id";

| ActiveJob spec doesn't work with ActionController::Parameters Posted: 02 Jan 2017 06:30 AM PST My test: describe TasksCsvsController do describe '#index' do let(:params) { {'clients' => {'id' => ['1', '2', '3']}} } before do ActiveJob::Base.queue_adapter = :test end it 'enqueues tasks csv job' do get :create, params: params expect(ProjectsCsvJob).to have_been_enqueued.with(params['clients']) end end end
The controller it tests: class TasksCsvsController < ApplicationController def create ProjectsCsvJob.perform_now(csv_params.to_unsafe_hash) redirect_to tasks_path, notice: I18n.t('flashes.tasks_csv_generating', email: current_user.email) end private def csv_params params.require(:clients).permit(:from, :to, tasks_grid: {}, id: []) end end
And the ActiveJob: class ProjectsCsvJob < ApplicationJob queue_as :default def perform(clients_params) # it does nothing end end
The test doesn't pass: Failure/Error: expect(ProjectsCsvJob).to have_been_enqueued.with(params['clients']) expected to enqueue exactly 1 jobs, with [{"id"=>["1", "2", "3"]}], but enqueued 0
This is strange, because when I debug during the test, params['clients'].to_unsafe_hash is what I expect. However, when I change the controller's line to ProjectsCsvJob.perform_later({'id' => ['1', '2', '3']})
the test passes. |

| Ajax not working inside iteration Posted: 02 Jan 2017 04:15 AM PST I have a AtpRank model containing the first 100 Atp tennis players.
My goal is to create in the view a table listing all tennis players and their attributes, along with a button for each player useful for the user to choose a list of tennis players. The home.html.erb code is below: <% @atp_ranks.each do |tennis_player| %> <tr id="tennist-<%= tennis_player.ranking %>"> <td class="atpranking"> <%= tennis_player.ranking %> </td> <td class="atpname"> <%= tennis_player.name %> </td> <td class="atppoints"> <%= tennis_player.points %> </td> <% unless Time.now.month == 12 %> <td> <div id="atpenlist_form"> <% if current_user.atpenlisted?(tennis_player) %> <%= form_for(current_user.atp_selections.find_by(atp_rank_id: tennis_player.id), html: { method: :delete }, remote: true) do |f| %> <%= f.submit "Dump", class: "btn btn-warning btn-sm" %> <% end %> <% else %> <%= form_for(current_user.atp_selections.build, remote: true) do |f| %> <div><%= hidden_field_tag :atp_id, tennis_player.id %></div> <%= f.submit "Choose", class: "btn btn-primary btn-sm" %> <% end %> <% end %> </div> </td> <% end %> </tr> <% end %>
As you can see, the form uses Ajax having set remote: true in the form_for helper. Requests are handled by the atp_selections controller. Below is an extract of the create action of this controller: current_user.atpenlist(tennist) respond_to do |format| format.html { redirect_to root_url } format.js end
The destroy action uses the atpdiscard method instead of the atpenlist method.
In app/views/atp_selections I created the create.js.erb and destroy.js.erb files.
Below is the app/views/atp_selections/create.js.erb file: $("#atpenlist_form").html("<%= escape_javascript(render('users/atpdiscard')) %>"); $("#atp_count").html('<%= current_user.atp_ranks.count %>');
Each of the app/view/users/_atpenlist.html.erb and app/view/users/_atpdiscard.html.erb partials contain the respective form (the same exact part of the code above starting with form_for). I have to say that in the original code for the home page I did not explicitly included the entire code for the forms, but I just rendered the partials. This did not work: rails warned me that it could not find the variable or method tennis_player used in the iteration, for some reason to me unknown. So I had to renounce to render the partials and decided to include the entire code. The issue is now that Ajax does not work: I have to refresh the page to see the results of submitting the form. I checked my code and could not find errors or explanation for this. |

| Undefined variable: "$global-breakpoint" wherever stylesheet_link_tag and javascript_link_tag is mentioned Posted: 02 Jan 2017 02:39 AM PST I have recently upgraded my Rails 3.2 application to Rails 5. After managing to run the application when I tried to access some pages this is the error I encountered: Undefined variable: "$global-breakpoint". Extracted source (around line #2) <div ng-controller="navigationController"> <%= stylesheet_link_tag 'header_b2c', media: 'all', 'data-turbolinks-track' => true %> <% current_user = nil unless defined?(current_user) %>
This is happening at all the places wherever I am using the stylesheet_link_tag or javascript_link_tag. The header_b2c in the case above is a normal css file in the assets/stylesheets directory. The same code used to work in rails 3.2. Searching for the error yields almost no result, is it something related to a config thing that I need to do in order to make the css files get interpreted as a css file instead of a sass file ? If not, what else might be the issue ? |

Do you have any idea what could be wrong or where could I search for a reason of this problem? EDIT: Command how I run tests: $ rake spec
EDIT 2: When I run server with Byebug in any place it also doesn't work. It even doesn't print any logs. This is how does it look console after running server and sending to them some requests - ... empty: 
That does it doesn't print in console could be caused by puma.rb configuration: min_threads_count = ENV.fetch('RAILS_MIN_THREADS') { 5 }.to_i max_threads_count = ENV.fetch('RAILS_MAX_THREADS') { 5 }.to_i threads min_threads_count, max_threads_count bind "unix:///var/run/puma.sock?umask=0000" stdout_redirect "/var/log/puma.stdout.log", "/var/log/puma.stderr.log", true environment ENV.fetch('RAILS_ENV') { 'development' } plugin :tmp_restart

| ActiveRecord callback or MySql trigger? Posted: 02 Jan 2017 05:47 AM PST Lets say we have two models: class Message < ActiveRecord::Base belongs_to :user has_many :statistics end class Statistic < ActiveRecord::Base belongs_to :user belongs_to :messages end
The Message has :state attribute and it has to be updated based on Statistic counts (i.g. delivered_at, read_at). Meaning once the message was delivered to every user in the group the state has to be updated accordingly.
The Statistics timestamps updated in a sidekiq jobs with a query that does not invoke the callback (update_all) so I can't hook into 'after_update' callback of the Statistics and update the Message.state.
I've tried to do it using MySql after update trigger on Statistics table but had no luck because the query that invokes the trigger has the destination table (messages) in join.
Please advise.
Hope I was clear enough.
Thank you. |
| Rails: Enable users to choose their roles when signing up on devise Posted: 02 Jan 2017 01:49 AM PST I'm using devise for my Rails project to authenticate users. There are several roles that users can choose from (e.g. admin, student, teacher), and I want the users to be able to choose their role when signing up. I've searched around and found ways to set a default role and enable users to change that role later, but I couldn't find a good resource for how to modify the devise controller and view to allow users to choose their role right away.

| Work around CORS Ember error for a Rails backend Posted: 02 Jan 2017 12:14 AM PST Building a front end interface using a Rails REST API, I get the error XMLHttpRequest cannot load http://www.example.com/questions No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access.
I've set up my adapter to be import DS from 'ember-data'; export default DS.RESTAdapter.extend({ namespace: 'api/v1', host: 'http://www.example.com' });
If I was building the API, I would just include the gem 'rack-cors' and allow for the access to other sites, but this is not included in the source. I'm just starting out with the Ember framework and haven't yet found a work around for this. I've tried running a proxy server ember s --proxy http://www.example.com
But I get the same response. Is there a piece of middleware or a method on the RESTAdapter that I can use to bypass this error? |
