$i18n.locale behaving differently in templates vs pages

[adamkendalnfa]

Using {{$i18n.locale}} in a page file gives the correct locale. However, using {{$i18n.locale}} in a template file always returns the default locale.

I am using Contentful (@gridsome/source-contentful) to generate template pages with localized data.

Expected behavior
I would expect {{$i18n.locale}} to behave the same in all gridsome file types (layouts, templates, pages).

Environment:

• Gridsome Version 0.7.0
  -gridsome-plugin-i18n version 1.6.0

gridsome.config.js

module.exports = {
  siteName: "siteName",
  templates: {
    ContentfulContentPage: [{
      path: (node) =>  `/${node.locale === 'en-US' ? 'en' : 'cn'}/${node.slug}`
    }],
  },
  plugins: [
    {
      use: "@gridsome/source-contentful",
      options: {
        space: {{space}}, // required
        accessToken: {{accessToken}}, // required
        typeName: "Contentful",
        locales: ["en-US", "zh-CN"],
      },
    },
    {
      use: "gridsome-plugin-i18n",
      options: {
        locales: [
          // locales list
          "en-US",
          "zh-CN",
        ],
        pathAliases: {
          // path segment alias for each locales
          "en-US": "en",
          "zh-CN": "cn",
        },
        fallbackLocale: "en-US", // fallback language
        defaultLocale: "en-US", // default language
        enablePathRewrite: false, // rewrite path with locale prefix, default: true
        rewriteDefaultLanguage: true, // rewrite default locale, default: true
      },
    },
    {
      use: "@noxify/gridsome-plugin-remote-image",
      options: {
        cache: false,
        typeName: "ContentfulAsset",
        sourceField: "file.url",
        targetField: "localFile",
        targetPath: "src/assets/cf/remoteImage",
      },
    },
  ],
};

I don't have a contentful source ready to go, but I tested with templates generated from both local yaml file and gridsome-source-sanity.

$i18n.locale contains correct values in both. Are you able to put together a repo with minimal app reproducing this issue?

Also take a look at this PR: #32

It has contentful source as an example as well. Could it be specific to this CMS? You can use this PR in your package.json if it fixes your issue as described in comments to this PR.
