Hi @O P. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To sum all data from a relationship array and display it in a column, you can follow these steps. The provided knowledge sources do not include a direct example for summing relationship data in a table, but you can adapt the general approach for handling relational data. Here's a general approach using refine with Ant Design: 1. Fetch the relational data: Ensure you are fetching the relational data correctly. You can use hooks like useTable to handle relational data. 2. Calculate the sum: Once you have the relational data, you can calculate the sum of the desired field. 3. Display the sum in a column: Add a custom column to your table to display the calculated sum. Here is a conceptual example:

import React from "react";
import { useTable } from "@refinedev/antd";
import { Table } from "antd";

const MyTableComponent = () => {
    const { tableProps } = useTable({
        resource: "your-resource",
        // other configurations
    });

    const columns = [
        {
            title: "ID",
            dataIndex: "id",
        },
        {
            title: "Name",
            dataIndex: "name",
        },
        {
            title: "Sum of Related Data",
            render: (text, record) => {
                // Assuming `relatedData` is the relationship array
                const sum = record.relatedData.reduce((acc, item) => acc + item.value, 0);
                return sum;
            },
        },
    ];

    return <Table {...tableProps} columns={columns} />;
};

export default MyTableComponent;

import React from "react";
import { useTable } from "@refinedev/antd";
import { Table } from "antd";

const MyTableComponent = () => {
    const { tableProps } = useTable({
        resource: "your-resource",
        // other configurations
    });

    const columns = [
        {
            title: "ID",
            dataIndex: "id",
        },
        {
            title: "Name",
            dataIndex: "name",
        },
        {
            title: "Sum of Related Data",
            render: (text, record) => {
                // Assuming `relatedData` is the relationship array
                const sum = record.relatedData.reduce((acc, item) => acc + item.value, 0);
                return sum;
            },
        },
    ];

    return <Table {...tableProps} columns={columns} />;
};

export default MyTableComponent;

In this example: - useTable is used to fetch the data. - The columns array defines the table columns, including a custom column that calculates the sum of a field (value) from the relatedData array. For more detailed information on handling relational data, you can refer to the refine documentation: - Handling Relational Data with useTable (Ant Design) (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-table#how-can-i-handle-relational-data) If you need more specific guidance or examples, please check the refine documentation or community support channels. ---------------------- 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: ---------------------- To display an array in a table column using refine with Ant Design, you can customize the column's render function to properly format and display the array data. Here is an example of how you can achieve this: 1. Fetch the data: Use useTable to fetch the data, including the array field. 2. Render the array: Customize the column's render function to display the array items. Here is a conceptual example:

import React from "react";
import { useTable } from "@refinedev/antd";
import { Table } from "antd";

const MyTableComponent = () => {
    const { tableProps } = useTable({
        resource: "your-resource",
        // other configurations
    });

    const columns = [
        {
            title: "ID",
            dataIndex: "id",
        },
        {
            title: "Name",
            dataIndex: "name",
        },
        {
            title: "Array Data",
            dataIndex: "arrayField",
            render: (array) => {
                return (
                    <ul>
                        {array.map((item, index) => (
                            <li key={index}>{item}</li>
                        ))}
                    </ul>
                );
            },
        },
    ];

    return <Table {...tableProps} columns={columns} />;
};

export default MyTableComponent;

import React from "react";
import { useTable } from "@refinedev/antd";
import { Table } from "antd";

const MyTableComponent = () => {
    const { tableProps } = useTable({
        resource: "your-resource",
        // other configurations
    });

    const columns = [
        {
            title: "ID",
            dataIndex: "id",
        },
        {
            title: "Name",
            dataIndex: "name",
        },
        {
            title: "Array Data",
            dataIndex: "arrayField",
            render: (array) => {
                return (
                    <ul>
                        {array.map((item, index) => (
                            <li key={index}>{item}</li>
                        ))}
                    </ul>
                );
            },
        },
    ];

    return <Table {...tableProps} columns={columns} />;
};

export default MyTableComponent;

In this example: - useTable is used to fetch the data. - The columns array defines the table columns, including a custom column for the array field (arrayField). - The render function for the arrayField column maps over the array and displays each item in a list (<ul> and <li>). This approach ensures that the array data is displayed in a readable format within the table. For more detailed information on handling relational data and customizing table columns, you can refer to the refine documentation: - Handling Relational Data with useTable (Ant Design) (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-table#how-can-i-handle-relational-data) ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

how to set my refine project default locale to chinese @kapa.ai

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To set the default locale of your refine project to Chinese, you need to configure the i18nProvider to use Chinese as the default language. Here are the steps to achieve this: 1. Create Translation Files: Create a translation file for Chinese (e.g., zh.json) in your project. 2. Configure the i18nProvider: Set up the i18nProvider to use Chinese as the default locale. 3. Pass the i18nProvider to the <Refine /> component: Ensure that the i18nProvider is passed to the <Refine /> component in your App.tsx. Here is an example of how you can do this: Step 1: Create Translation Files Create a file named zh.json in your locales directory with the necessary translations. For example:

{
  "pages": {
    "login": {
      "title": "登录到您的账户",
      "signin": "登录",
      "signup": "注册",
      "divider": "或",
      "fields": {
        "email": "电子邮件",
        "password": "密码"
      },
      "errors": {
        "validEmail": "无效的电子邮件地址",
        "requiredEmail": "电子邮件是必需的",
        "requiredPassword": "密码是必需的"
      },
      "buttons": {
        "submit": "登录",
        "forgotPassword": "忘记密码？",
        "noAccount": "没有账户？",
        "rememberMe": "记住我"
      }
    }
  }
}

{
  "pages": {
    "login": {
      "title": "登录到您的账户",
      "signin": "登录",
      "signup": "注册",
      "divider": "或",
      "fields": {
        "email": "电子邮件",
        "password": "密码"
      },
      "errors": {
        "validEmail": "无效的电子邮件地址",
        "requiredEmail": "电子邮件是必需的",
        "requiredPassword": "密码是必需的"
      },
      "buttons": {
        "submit": "登录",
        "forgotPassword": "忘记密码？",
        "noAccount": "没有账户？",
        "rememberMe": "记住我"
      }
    }
  }
}

Step 2: Configure the i18nProvider Create an i18nProvider that uses Chinese as the default locale. For example:

import { I18nProvider } from "@refinedev/core";
import i18n from "i18next";
import { initReactI18next } from "react-i18next";
import zh from "./locales/zh.json";

i18n.use(initReactI18next).init({
  resources: {
    zh: {
      translation: zh,
    },
  },
  lng: "zh", // Set default language to Chinese
  fallbackLng: "zh",
  interpolation: {
    escapeValue: false,
  },
});
const i18nProvider: I18nProvider = {
  translate: (key: string, options?: any) => i18n.t(key, options),
  changeLocale: (lang: string) => {
    i18n.changeLanguage(lang);
    return Promise.resolve();
  },
  getLocale: () => i18n.language,
};

export default i18nProvider;

import { I18nProvider } from "@refinedev/core";
import i18n from "i18next";
import { initReactI18next } from "react-i18next";
import zh from "./locales/zh.json";

i18n.use(initReactI18next).init({
  resources: {
    zh: {
      translation: zh,
    },
  },
  lng: "zh", // Set default language to Chinese
  fallbackLng: "zh",
  interpolation: {
    escapeValue: false,
  },
});
const i18nProvider: I18nProvider = {
  translate: (key: string, options?: any) => i18n.t(key, options),
  changeLocale: (lang: string) => {
    i18n.changeLanguage(lang);
    return Promise.resolve();
  },
  getLocale: () => i18n.language,
};

export default i18nProvider;

Step 3: Pass the i18nProvider to the <Refine /> component Ensure that the i18nProvider is passed to the <Refine /> component in your App.tsx:

import React from "react";
import { Refine } from "@refinedev/core";
import i18nProvider from "./i18nProvider";

const App: React.FC = () => {
  return (
    <Refine
      i18nProvider={i18nProvider}
      /* other props */
    >
      {/* other components */}
    </Refine>
  );
};

export default App;

import React from "react";
import { Refine } from "@refinedev/core";
import i18nProvider from "./i18nProvider";

const App: React.FC = () => {
  return (
    <Refine
      i18nProvider={i18nProvider}
      /* other props */
    >
      {/* other components */}
    </Refine>
  );
};

export default App;

By following these steps, you will set the default locale of your refine project to Chinese.
