From cd4f2518914bfb7b6c6ae9e35bd2bf2dfb4b6147 Mon Sep 17 00:00:00 2001 From: Jarek Radosz Date: Thu, 6 Aug 2020 17:57:06 +0200 Subject: [PATCH] FEATURE: Poll breakdown 2.0 (#10345) The poll breakdown modal replaces the grouped pie charts feature. Includes: * MODAL: Untangle `onSelectPanel` Previously modal-tab component would call on click the onSelectPanel callback with itself (modal-tab) as `this` which severely limited its usefulness. Now showModal binds the callback to its controller. "The PR includes a fix/change to d-modal (b7f6ec6) that hasn't been extracted to a separate PR because it's not currently possible to test a change like this in abstract, i.e. with dynamically created controllers/components in tests. The percentage/count toggle test for the poll breakdown feature is essentially a test for that d-modal modification." --- .../discourse/app/components/modal-tab.js | 6 +- .../discourse/app/lib/show-modal.js | 5 +- .../app/mixins/modal-functionality.js | 4 - app/assets/stylesheets/common/base/modal.scss | 2 +- lib/tasks/javascript.rake | 3 + package.json | 1 + .../components/poll-breakdown-chart.js.es6 | 182 +++++++++++++++++ .../components/poll-breakdown-option.js.es6 | 61 ++++++ .../controllers/poll-breakdown.js.es6 | 83 ++++++++ .../controllers/poll-ui-builder.js.es6 | 2 +- .../components/poll-breakdown-chart.hbs | 2 + .../components/poll-breakdown-option.hbs | 17 ++ .../templates/modal/poll-breakdown.hbs | 49 +++++ .../initializers/add-poll-ui-builder.js.es6 | 2 +- .../initializers/extend-for-poll.js.es6 | 4 +- .../javascripts/widgets/discourse-poll.js.es6 | 184 +++--------------- .../stylesheets/common/poll-breakdown.scss | 116 +++++++++++ .../poll/assets/stylesheets/common/poll.scss | 27 +-- .../poll/assets/stylesheets/desktop/poll.scss | 5 +- .../poll/assets/stylesheets/mobile/poll.scss | 8 +- plugins/poll/config/locales/client.en.yml | 11 +- plugins/poll/plugin.rb | 1 + .../acceptance/poll-breakdown-test.js.es6 | 119 +++++++++++ .../acceptance/poll-pie-chart-test.js.es6 | 96 +-------- .../chartjs-plugin-datalabels.min.js | 7 + yarn.lock | 5 + 26 files changed, 708 insertions(+), 294 deletions(-) create mode 100644 plugins/poll/assets/javascripts/components/poll-breakdown-chart.js.es6 create mode 100644 plugins/poll/assets/javascripts/components/poll-breakdown-option.js.es6 create mode 100644 plugins/poll/assets/javascripts/controllers/poll-breakdown.js.es6 create mode 100644 plugins/poll/assets/javascripts/discourse/templates/components/poll-breakdown-chart.hbs create mode 100644 plugins/poll/assets/javascripts/discourse/templates/components/poll-breakdown-option.hbs create mode 100644 plugins/poll/assets/javascripts/discourse/templates/modal/poll-breakdown.hbs create mode 100644 plugins/poll/assets/stylesheets/common/poll-breakdown.scss create mode 100644 plugins/poll/test/javascripts/acceptance/poll-breakdown-test.js.es6 create mode 100644 public/javascripts/chartjs-plugin-datalabels.min.js diff --git a/app/assets/javascripts/discourse/app/components/modal-tab.js b/app/assets/javascripts/discourse/app/components/modal-tab.js index 3211fbbdd2..a798e22d6d 100644 --- a/app/assets/javascripts/discourse/app/components/modal-tab.js +++ b/app/assets/javascripts/discourse/app/components/modal-tab.js @@ -20,6 +20,10 @@ export default Component.extend({ }, click() { - this.onSelectPanel(this.panel);
