bootstrap3 datetimepicker cannot load the locale - ruby-on-rails-4

Question

(Using Rails 4 ) I am trying to display the bootstrap3 datetimepicker in the current locale , it's working fine in english , but when I try to insert the require locale file in the application.js ( as stated in the doc) , I get an error :
[Error] TypeError: undefined is not an object (evaluating '$.fn.datetimepicker.dates')
(anonymous function) (application.js, line 15026)
in my assets, the application.js , I have :
//= require jquery
//= require jquery_ujs
//= require bootstrap.min
//= require moment
//= require bootstrap-datetimepicker
//= require pickers
// You may include any languages (optional)
//= require locales/bootstrap-datetimepicker.fr
the bootstrap-datetimepicker.fr.js file is the following :
;(function($){
$.fn.datetimepicker.dates['fr'] = {
days: ["Dimanche", "Lundi", "Mardi", "Mercredi", "Jeudi", "Vendredi", "Samedi", "Dimanche"],
daysShort: ["Dim", "Lun", "Mar", "Mer", "Jeu", "Ven", "Sam", "Dim"],
daysMin: ["D", "L", "Ma", "Me", "J", "V", "S", "D"],
months: ["Janvier", "Février", "Mars", "Avril", "Mai", "Juin", "Juillet", "Août", "Septembre", "Octobre", "Novembre", "Décembre"],
monthsShort: ["Jan", "Fev", "Mar", "Avr", "Mai", "Jui", "Jul", "Aou", "Sep", "Oct", "Nov", "Dec"],
today: "Aujourd'hui"
};
}(jQuery));
maybe this javascript content is not right... but why ? or is there another issue ?
problem is not with the datetimepicker as it's displayed correctly in english ( default)

Answer 1

withe this latest version, using moments.js ... I SHOUDL use the moments locales !!!
so my bootstrap-datetimepicker.fr.js should be :
// moment.js locale configuration
// locale : french (fr)
// author : John Fischer : https://github.com/jfroffice
(function (factory) {
if (typeof define === 'function' && define.amd) {
define(['moment'], factory); // AMD
} else if (typeof exports === 'object') {
module.exports = factory(require('../moment')); // Node
} else {
factory(window.moment); // Browser global
}
}(function (moment) {
return moment.defineLocale('fr', {
months : 'janvier_février_mars_avril_mai_juin_juillet_août_septembre_octobre_novembre_décembre'.split('_'),
monthsShort : 'janv._févr._mars_avr._mai_juin_juil._août_sept._oct._nov._déc.'.split('_'),
weekdays : 'dimanche_lundi_mardi_mercredi_jeudi_vendredi_samedi'.split('_'),
weekdaysShort : 'dim._lun._mar._mer._jeu._ven._sam.'.split('_'),
weekdaysMin : 'Di_Lu_Ma_Me_Je_Ve_Sa'.split('_'),
longDateFormat : {
LT : 'HH:mm',
L : 'DD/MM/YYYY',
LL : 'D MMMM YYYY',
LLL : 'D MMMM YYYY LT',
LLLL : 'dddd D MMMM YYYY LT'
},
calendar : {
sameDay: '[Aujourd\'hui à] LT',
nextDay: '[Demain à] LT',
nextWeek: 'dddd [à] LT',
lastDay: '[Hier à] LT',
lastWeek: 'dddd [dernier à] LT',
sameElse: 'L'
},
relativeTime : {
future : 'dans %s',
past : 'il y a %s',
s : 'quelques secondes',
m : 'une minute',
mm : '%d minutes',
h : 'une heure',
hh : '%d heures',
d : 'un jour',
dd : '%d jours',
M : 'un mois',
MM : '%d mois',
y : 'un an',
yy : '%d ans'
},
ordinal : function (number) {
return number + (number === 1 ? 'er' : '');
},
week : {
dow : 1, // Monday is the first day of the week.
doy : 4 // The week that contains Jan 4th is the first week of the year.
}
});
