In my page strings are not translated

Hello i created a page through the inferencer code, now i'm using this code but strings are not translated and it seems that current locale is not used. Thi is the code: import React from "react"; import { useLocale } from 'react-admin' import { useDataGrid, EditButton, ShowButton, DeleteButton, List, DateField, } from "@refinedev/mui"; import { DataGrid, GridColDef } from "@mui/x-data-grid"; import { IResourceComponentsProps, useTranslate } from "@refinedev/core"; const SorgentiList: React.FC<IResourceComponentsProps> = () => { const translate = useTranslate(); const { dataGridProps } = useDataGrid(); const columns = React.useMemo<GridColDef[]>( () => [ /* columnsDefinition */ ], [translate], ); return ( <List> <DataGrid {...dataGridProps} columns={columns} autoHeight /> </List> ); }; export default SorgentiList;

Hi @atti_effe. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- It seems like you're using the useTranslate hook from refine, but you might not have set up the i18nProvider correctly. The i18nProvider is necessary for the useTranslate hook to work. Here's how you can set up the i18nProvider:

import { I18nProvider } from "@refinedev/core";  
import { useTranslation } from "react-i18next";  

const App: React.FC = () => {  
 const { t, i18n } = useTranslation();  

 const i18nProvider: I18nProvider = {  
 translate: (key: string, options?: any) => t(key, options),  
 changeLocale: (lang: string) => i18n.changeLanguage(lang),  
 getLocale: () => i18n.language,  
 };  

 return (  
 <Refine  
 i18nProvider={i18nProvider}  
 /* ... */  
 >  
 {/* ... */}  
 </Refine>  
 );  
};

import { I18nProvider } from "@refinedev/core";  
import { useTranslation } from "react-i18next";  

const App: React.FC = () => {  
 const { t, i18n } = useTranslation();  

 const i18nProvider: I18nProvider = {  
 translate: (key: string, options?: any) => t(key, options),  
 changeLocale: (lang: string) => i18n.changeLanguage(lang),  
 getLocale: () => i18n.language,  
 };  

 return (  
 <Refine  
 i18nProvider={i18nProvider}  
 /* ... */  
 >  
 {/* ... */}  
 </Refine>  
 );  
};

In this example, we're using react-i18next as the i18n library. The i18nProvider is then passed to the Refine component. After setting up the i18nProvider, you should be able to use the useTranslate hook in your components:

import { useTranslate } from "@refinedev/core";  

export const MyComponent = () => {  
 const translate = useTranslate();  

 return <button>{translate("my.translate.text")}</button>;  
};

import { useTranslate } from "@refinedev/core";  

export const MyComponent = () => {  
 const translate = useTranslate();  

 return <button>{translate("my.translate.text")}</button>;  
};

Remember that the useTranslate hook can only be used if i18nProvider is provided. For more information, you can check out the refine i18n Provider documentation (https://refine.dev/docs/core/providers/i18n-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

i have done everything but if i use this code i18n.language gives me null. It worked well used the standard inferencer code : const { t, i18n } = useTranslation(); const i18nProvider = { translate: (key: string, params: object) => t(key, params), changeLocale: (lang: string) => i18n.changeLanguage(lang), getLocale: () => i18n.language, }; console.log("I18n lang",i18n.language); @kapa.ai i have done everything but if i use this code i18n.language gives me null.

Let me check the knowledge base for you. One moment! :books: ---------------------- If i18n.language is returning null, it might be because the i18n instance is not fully initialized when it's being accessed. The i18n instance from react-i18next is asynchronous and might not be ready when your component is rendering. You can use the i18n.isInitialized property to check if the instance is ready:

const App: React.FC = () => {
 const { t, i18n } = useTranslation();

 console.log("i18n initialized", i18n.isInitialized); // Check if i18n is initialized
 console.log("i18n language", i18n.language); // Log the current language

 const i18nProvider: I18nProvider = {
  translate: (key: string, options?: any) => t(key, options),
  changeLocale: (lang: string) => i18n.changeLanguage(lang),
  getLocale: () => i18n.language,
 };

 return (
  <Refine
   i18nProvider={i18nProvider}
   /* ... */
  >
   {/* ... */}
  </Refine>
 );
};

const App: React.FC = () => {
 const { t, i18n } = useTranslation();

 console.log("i18n initialized", i18n.isInitialized); // Check if i18n is initialized
 console.log("i18n language", i18n.language); // Log the current language

 const i18nProvider: I18nProvider = {
  translate: (key: string, options?: any) => t(key, options),
  changeLocale: (lang: string) => i18n.changeLanguage(lang),
  getLocale: () => i18n.language,
 };

 return (
  <Refine
   i18nProvider={i18nProvider}
   /* ... */
  >
   {/* ... */}
  </Refine>
 );
};

If i18n.isInitialized is false, then the i18n instance is not ready and i18n.language will be null. You might need to add some logic to wait for the i18n instance to be ready before rendering your components. For more information, you can check out the react-i18next documentation (https://react.i18next.com). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

how can i render the component only after i18n is initialized? @kapa.ai how can i render the component only after i18n is initialized?

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- You can use the ready state from the useTranslation hook to conditionally render your component. The ready state is true when the i18n instance is initialized and ready to use. Here's an example:

import { useTranslation } from "react-i18next";
import { I18nProvider } from "@refinedev/core";  
import { Refine } from "@refinedev/core";  

const App: React.FC = () => {
  const { t, i18n, ready } = useTranslation();

  const i18nProvider: I18nProvider = {
    translate: (key: string, options?: any) => t(key, options),
    changeLocale: (lang: string) => i18n.changeLanguage(lang),
    getLocale: () => i18n.language,
  };

  if (!ready) {
    return <div>Loading...</div>; // or your custom loading component
  }

  return (
    <Refine
      i18nProvider={i18nProvider}
      /* ... */
    >
      {/* ... */}
    </Refine>
  );
};

import { useTranslation } from "react-i18next";
import { I18nProvider } from "@refinedev/core";  
import { Refine } from "@refinedev/core";  

const App: React.FC = () => {
  const { t, i18n, ready } = useTranslation();

  const i18nProvider: I18nProvider = {
    translate: (key: string, options?: any) => t(key, options),
    changeLocale: (lang: string) => i18n.changeLanguage(lang),
    getLocale: () => i18n.language,
  };

  if (!ready) {
    return <div>Loading...</div>; // or your custom loading component
  }

  return (
    <Refine
      i18nProvider={i18nProvider}
      /* ... */
    >
      {/* ... */}
    </Refine>
  );
};

In this example, the Refine component (and the rest of your app) will only be rendered after the i18n instance is initialized. Before that, a loading message (or your custom loading component) will be displayed. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you. One moment! :books: ---------------------- If the translate function from useTranslate is not working, it might be because the i18n instance is not fully initialized when it's being accessed. The useTranslate hook relies on the i18nProvider that you provide to the Refine component, and this provider should be based on your i18n library (like react-i18next). To ensure that your i18n instance is fully loaded before your component renders, you can use the ready state from the useTranslation hook from react-i18next. This state is true when the i18n instance is initialized and ready to use. Here's an example of how you can do this:

import React from "react";
import { useTranslation } from "react-i18next";
import { useTranslate, I18nProvider } from "@refinedev/core";
import { Refine } from "@refinedev/core";

const App: React.FC = () => {
  const { t, i18n, ready } = useTranslation();

  const i18nProvider: I18nProvider = {
    translate: (key: string, options?: any) => t(key, options),
    changeLocale: (lang: string) => i18n.changeLanguage(lang),
    getLocale: () => i18n.language,
  };

  if (!ready) {
    return <div>Loading...</div>; // or your custom loading component
  }

  return (
    <Refine
      i18nProvider={i18nProvider}
      /* ... */
    >
      {/* ... */}
    </Refine>
  );
};

import React from "react";
import { useTranslation } from "react-i18next";
import { useTranslate, I18nProvider } from "@refinedev/core";
import { Refine } from "@refinedev/core";

const App: React.FC = () => {
  const { t, i18n, ready } = useTranslation();

  const i18nProvider: I18nProvider = {
    translate: (key: string, options?: any) => t(key, options),
    changeLocale: (lang: string) => i18n.changeLanguage(lang),
    getLocale: () => i18n.language,
  };

  if (!ready) {
    return <div>Loading...</div>; // or your custom loading component
  }

  return (
    <Refine
      i18nProvider={i18nProvider}
      /* ... */
    >
      {/* ... */}
    </Refine>
  );
};

In this example, the Refine component (and the rest of your app) will only be rendered after the i18n instance is initialized. Before that, a loading message (or your custom loading component) will be displayed.

@kapa.ai doing like that it just freeze showing Loading and never go forward

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If your application is stuck on the loading state, it might be because the i18n instance is not initializing correctly. This could be due to a variety of reasons, such as incorrect configuration or missing translation files. Here are a few things you can check: 1. Check your i18n configuration: Make sure that your i18n library (like react-i18next) is correctly set up. This includes setting the correct language resources and initializing the library correctly. 2. Check your translation files: Make sure that the translation files for your default language are available and correctly formatted. If the i18n library can't find or parse these files, it might fail to initialize. 3. Check for errors: Check your browser's console for any error messages. These might give you a clue about what's going wrong. If everything seems to be in order, you might want to try manually initializing the i18n instance and see if that helps. Here's an example of how you can do this with react-i18next:

import i18n from "i18next";
import { initReactI18next } from "react-i18next";

// Initialize i18n
i18n
  .use(initReactI18next) // Passes i18n down to react-i18next
  .init({
    resources: {
      en: {
        translation: {
          // Your translations go here
        },
      },
      // Other languages...
    },
    lng: "en", // Your default language
    fallbackLng: "en", // Fallback language
    interpolation: {
      escapeValue: false, // React already does escaping
    },
  });

import i18n from "i18next";
import { initReactI18next } from "react-i18next";

// Initialize i18n
i18n
  .use(initReactI18next) // Passes i18n down to react-i18next
  .init({
    resources: {
      en: {
        translation: {
          // Your translations go here
        },
      },
      // Other languages...
    },
    lng: "en", // Your default language
    fallbackLng: "en", // Fallback language
    interpolation: {
      escapeValue: false, // React already does escaping
    },
  });

After initializing the i18n instance, you can then use it in your i18nProvider:

const i18nProvider: I18nProvider = {
  translate: (key: string, options?: any) => i18n.t(key, options),
  changeLocale: (lang: string) => i18n.changeLanguage(lang),
  getLocale: () => i18n.language,
};

const i18nProvider: I18nProvider = {
  translate: (key: string, options?: any) => i18n.t(key, options),
  changeLocale: (lang: string) => i18n.changeLanguage(lang),
  getLocale: () => i18n.language,
};

For more information, you can check out the react-i18next documentation (https://react.i18next.com). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
