Testing leaflet and d3.js (version 4) with Ruby on Rails 5.
It also uses React with Broserify. Two buildpack have been added to Heroku to acheive this. The javascript classes handled by Browserify are built with a node process then the Rails built process is launched.
- 'jquery'
- 'jquery-ujs'
- 'font-awesome'
- 'jquery-tokeninput'
- 'foundation-sites'
- 'leaflet'
- 'leaflet-providers'
- 'leaflet-ajax'
- 'd3'
- 'topojson'
- The SASS file used the .sass and not the .scss extention
- The Javascript file is written using the CoffeeScript dialect
- The Html is written using HAML.
- The project uses Zurb Foundation 6 framework as CSS Framework
- It uses semantic css (with haml it makes clean code)
Les fichiers de données sont dans le dossier /public du projet.
provinces.geojson permettent d'afficher les frontières entre les provinces canadiennes et/ou les états des USA. (Source: Natural Earth). J'ai utilisé les fichier de type ESRI-Shapefiles que j'ai converti en geojson puis en topojson.
mtl.json est un fichier topjson contenant plusieurs topologies dont les limites entre les circonscriptions et les limites des sections de vote dans plusieurs circonscriptons. J'ai utilisé des fichiers ESRI-Shapefiles fournis par le DGEQ pour extraire les données pertinentes et les organiser afin de minimiser le volume du fichier.
resultats.json est un fichier geojson donnant les résultats pour les les 125 circonscriptions et je crois que je l'ai utilisé tel que fourni par le DGEQ.
Le sous-répertoire '2014-04-07' contient une série de fichiers donnant les résultats par section de vote circonscription par circonsriptions. Ces fichiers ont été modifiés comme suits:
Nom original: nom_circonscription.csv Nom intermédiaire: zxxx.csv
Où xxx est le numéro (code d'identification) de la circonscription.
Conversion de l'encodage du fichier de ISO-8859-1 (zxxx.csv) vers un encodage UTF-8.
See: http://www.electionsquebec.qc.ca/francais/provincial/carte-electorale/geometrie-des-circonscriptions-provinciales-du-quebec-2014.php to get the appropriate zip file containing the ESRI Shapefile files. Once unzipped, run the following commands to get the topojson file used in the project. Move the resulting file into the /public directory.
Two (2) zip files must be downloaded and treated. The 2011 section contains constituencies (circonscriptions or comtés in French) shapes and the 2014 section goes inside each constituency with the shapefile of every voting section.
The last section (not used in this project), labeled 2012, contains the voting section used on the September 4th. 2012 general elections.
