Hi @mauryo. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To handle errors in the useRegister hook and show them in the input fields, you can follow the approach outlined in the provided knowledge sources. Since the authProvider methods always return a resolved promise, you need to handle errors using the success value in the response. Here's a step-by-step guide to achieve this: 1. Import and Use useRegister Hook: Import the useRegister hook from @refinedev/core. 2. Handle the Registration Process: Use the mutate function from the useRegister hook to handle the registration process. 3. Check for Errors: In the onSuccess callback, check if the success value is false. If it is, handle the error accordingly. 4. Display Errors in Input Fields: Use state to manage and display error messages in the input fields. Here is an example implementation:

import React, { useState } from "react";
import { useRegister } from "@refinedev/core";
import { Form, Input, Button } from "antd";

const UserCreate = () => {
    const { mutate: register } = useRegister();
    const [form] = Form.useForm();
    const [errors, setErrors] = useState({});

    const onSubmit = (values) => {
        register(
            {
                email: values.email,
                password: values.password,
            },
            {
                onSuccess: (data) => {
                    if (!data.success) {
                        // Handle error
                        setErrors(data.error);
                    } else {
                        // Handle success
                        alert("User created successfully!");
                    }
                },
            }
        );
    };
return (
        <Form form={form} onFinish={onSubmit} layout="inline" style={{ marginBottom: "20px", display: "flex", gap: "10px" }}>
            <Form.Item
                name="email"
                rules={[{ required: true, message: "Please input the email!" }, { type: "email", message: "Invalid email!" }]}
                validateStatus={errors.email ? "error" : ""}
                help={errors.email}
            >
                <Input placeholder="Email" />
            </Form.Item>
            <Form.Item
                name="password"
                rules={[{ required: true, message: "Please input the password!" }]}
                validateStatus={errors.password ? "error" : ""}
                help={errors.password}
            >
                <Input type="password" placeholder="Password" />
            </Form.Item>
            <Form.Item>
                <Button type="primary" htmlType="submit">
                    Create Account
                </Button>
            </Form.Item>
        </Form>
    );
};

export default UserCreate;

import React, { useState } from "react";
import { useRegister } from "@refinedev/core";
import { Form, Input, Button } from "antd";

const UserCreate = () => {
    const { mutate: register } = useRegister();
    const [form] = Form.useForm();
    const [errors, setErrors] = useState({});

    const onSubmit = (values) => {
        register(
            {
                email: values.email,
                password: values.password,
            },
            {
                onSuccess: (data) => {
                    if (!data.success) {
                        // Handle error
                        setErrors(data.error);
                    } else {
                        // Handle success
                        alert("User created successfully!");
                    }
                },
            }
        );
    };
return (
        <Form form={form} onFinish={onSubmit} layout="inline" style={{ marginBottom: "20px", display: "flex", gap: "10px" }}>
            <Form.Item
                name="email"
                rules={[{ required: true, message: "Please input the email!" }, { type: "email", message: "Invalid email!" }]}
                validateStatus={errors.email ? "error" : ""}
                help={errors.email}
            >
                <Input placeholder="Email" />
            </Form.Item>
            <Form.Item
                name="password"
                rules={[{ required: true, message: "Please input the password!" }]}
                validateStatus={errors.password ? "error" : ""}
                help={errors.password}
            >
                <Input type="password" placeholder="Password" />
            </Form.Item>
            <Form.Item>
                <Button type="primary" htmlType="submit">
                    Create Account
                </Button>
            </Form.Item>
        </Form>
    );
};

export default UserCreate;

Explanation: - Form Setup: The form is created using Ant Design components. - State Management: The errors state is used to store and display error messages. - Error Handling: In the onSuccess callback of the register function, if data.success is false, the error messages are set in the errors state. - Displaying Errors: The validateStatus and help properties of Form.Item are used to display error messages. For more details, you can refer to the useRegister documentation (https://refine.dev/docs/authentication/hooks/use-register/#error-handling). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai if i use typescript, whitch is the type for the error?

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- When using TypeScript, you can define the type for the error based on the HttpError type provided in the knowledge sources. The HttpError type is defined as follows:

type HttpError = {  
  message: string;  
  statusCode: number;  
  errors?: ValidationErrors;  
  [key: string]: any;  
};

type HttpError = {  
  message: string;  
  statusCode: number;  
  errors?: ValidationErrors;  
  [key: string]: any;  
};

You can use this type to type the error in your component. Here is how you can integrate it into the previous example:

import React, { useState } from "react";
import { useRegister } from "@refinedev/core";
import { Form, Input, Button } from "antd";

type HttpError = {  
  message: string;  
  statusCode: number;  
  errors?: ValidationErrors;  
  [key: string]: any;  
};  

const UserCreate: React.FC = () => {
    const { mutate: register } = useRegister();
    const [form] = Form.useForm();
    const [errors, setErrors] = useState<Partial<HttpError>>({});

    const onSubmit = (values: { email: string; password: string }) => {
        register(
            {
                email: values.email,
                password: values.password,
            },
            {
                onSuccess: (data) => {
                    if (!data.success) {
                        // Handle error
                        setErrors(data.error as HttpError);
                    } else {
                        // Handle success
                        alert("User created successfully!");
                    }
                },
            }
        );
    };
return (
        <Form form={form} onFinish={onSubmit} layout="inline" style={{ marginBottom: "20px", display: "flex", gap: "10px" }}>
            <Form.Item
                name="email"
                rules={[{ required: true, message: "Please input the email!" }, { type: "email", message: "Invalid email!" }]}
                validateStatus={errors.email ? "error" : ""}
                help={errors.email}
            >
                <Input placeholder="Email" />
            </Form.Item>
            <Form.Item
                name="password"
                rules={[{ required: true, message: "Please input the password!" }]}
                validateStatus={errors.password ? "error" : ""}
                help={errors.password}
            >
                <Input type="password" placeholder="Password" />
            </Form.Item>
            <Form.Item>
                <Button type="primary" htmlType="submit">
                    Create Account
                </Button>
            </Form.Item>
        </Form>
    );
};

export default UserCreate;

import React, { useState } from "react";

import { Form, Input, Button } from "antd";

type HttpError = {

  [key: string]: any;  
};  

const UserCreate: React.FC = () => {
    const { mutate: register } = useRegister();
    const [form] = Form.useForm();
    const [errors, setErrors] = useState<Partial<HttpError>>({});

    const onSubmit = (values: { email: string; password: string }) => {
        register(
            {
                email: values.email,
                password: values.password,
            },
            {
                onSuccess: (data) => {
                    if (!data.success) {
                        // Handle error
                        setErrors(data.error as HttpError);
                    } else {
                        // Handle success
                        alert("User created successfully!");
                    }
                },
            }
        );
    };
return (
        <Form form={form} onFinish={onSubmit} layout="inline" style={{ marginBottom: "20px", display: "flex", gap: "10px" }}>
            <Form.Item
                name="email"
                rules={[{ required: true, message: "Please input the email!" }, { type: "email", message: "Invalid email!" }]}
                validateStatus={errors.email ? "error" : ""}
                help={errors.email}
            >
                <Input placeholder="Email" />
            </Form.Item>
            <Form.Item
                name="password"
                rules={[{ required: true, message: "Please input the password!" }]}
                validateStatus={errors.password ? "error" : ""}
                help={errors.password}
            >
                <Input type="password" placeholder="Password" />
            </Form.Item>
            <Form.Item>
                <Button type="primary" htmlType="submit">
                    Create Account
                </Button>
            </Form.Item>
        </Form>
    );
};

export default UserCreate;

Explanation: - Type Definition: The HttpError type is defined and used to type the errors state. - State Management: The errors state is typed as Partial<HttpError> to allow for partial updates. - Error Handling: The error from the onSuccess callback is cast to HttpError before setting it in the state. For more details, you can refer to the HttpError documentation (https://refine.dev/docs/core/interface-references/#httperror). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
