如何首先为 JSON 文件使用两个转换器，然后为 firestore 使用两个转换器? [英] How can I use two translators first for JSON file and second for firestore?

问题描述

JSON 文件方法

export function createTranslateLoader(http: HttpClient) {
  return new TranslateHttpLoader(http, './assets/i18n/', '.json');
}

JSON 文件加载器

 TranslateModule.forRoot({
          loader: {
              provide: TranslateLoader,
              useFactory: (createTranslateLoader),
              deps: [HttpClient]
          }
      }),

AngularFirestore 方法

export function FirestoreTranslationsLoaderFactory(db: AngularFirestore) {
  return new FirestoreTransLoader(db);
}

AngularFirestore 文件加载器

TranslateModule.forRoot({
      loader: {
           provide: TranslateLoader,
           useFactory: FirestoreTranslationsLoaderFactory, 
           deps: [AngularFirestore]
        }
    }),

注意:我不能同时使用两个方法和 Loader 进行合并.

推荐答案

就像我已经在评论区回答你一样:

Like I have already answered you in the comments section:

我认为理论上将一份数据分别存储在两个地方并不是最好的主意.

I think that storing theoretically one piece of data separately in two places is not the best idea.

但如果你需要类似的东西，你可以使用 MissingTranslationHandler 就像我在这里所做的那样:
https://github.com/Mr-Eluzive/angularfire-ngx-translate-example/tree/missing-translation-handler
您可以查看此分支和 master 之间的差异，以熟悉需要做什么才能使其正常工作.

But if you need something like that you can use MissingTranslationHandler like I have done here:
https://github.com/Mr-Eluzive/angularfire-ngx-translate-example/tree/missing-translation-handler
You can check out diffs between this branch and master to get familiar with what has to bo done to make it works.
