@haddadzineddine, when using your branch

I got this error

because you updated the configuration variable $HOME_PAGE_LOGOS, like so

$HOME_PAGE_LOGOS = [
  {
    title: {
      en: 'Supported by',
      fr: 'Soutenu par',
    },
    ....

But as we discussed, we want all internationalization to be done in the local files not in the configuration files which need to be generic and no language-related.

[syphax-bouazzouni]

Added:

• Update the $HOME_PAGE_LOGOS config variable to be internationalized (0ddcd57)
• Rename 'set_locale' to 'set_locale_language' to prevent name conflicts (b77c27f)
• Add rails-i18n gem to add french dates localization (6914388)
• Add localization for the ontology_viewer header (9644023)

Good work;

Two remarks:

• It does not work for the browse page, will be fixed with this Feature: Update browse page design #217
• The summary page is not fully localized, will be fixed when we update it to the new UI
