Hi @parothia. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Hmm, I don't know enough to give you a confident answer yet. The code you provided seems to be a form item in a React component using Ant Design, which is part of the Refine framework. However, without more context, it's hard to determine why the systemBalance isn't loading. It could be due to several reasons such as the systemBalance variable not being defined or not having a value at the time of rendering. Also, ensure that the t function (which seems to be a translation function) is correctly implemented and returning the expected string. For more information on how to use forms in Refine, you can check out the documentation (https://refine.dev/docs/advanced-tutorials/forms/custom-form-validation/) and blogs (https://refine.dev/blog) provided. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai useEffect(() => { if (data.systemBalance) { setSystemBalance(data.systemBalance); } });

Let me check the knowledge base for you. One moment! :books: ---------------------- The code you provided is a useEffect hook in React. This hook is used to perform side effects in function components. Side effects are anything that interacts with the world outside of the scope of the current function, such as network requests, timers, and manual DOM manipulations. In your code, the useEffect hook is checking if data.systemBalance exists. If it does, it sets the state of systemBalance using the setSystemBalance function. This hook will run after every render because it doesn't have a dependency array. Here's a brief explanation of your code:

useEffect(() => {
    // Check if data.systemBalance exists
    if (data.systemBalance) {
      // If it does, update the systemBalance state
      setSystemBalance(data.systemBalance);
    }
});

useEffect(() => {
    // Check if data.systemBalance exists
    if (data.systemBalance) {
      // If it does, update the systemBalance state
      setSystemBalance(data.systemBalance);
    }
});

If you want this effect to run only once after the initial render (similar to componentDidMount in class components), you can pass an empty array [] as a second argument to useEffect:

useEffect(() => {
    if (data.systemBalance) {
      setSystemBalance(data.systemBalance);
    }
}, []); // Empty array means this effect runs once after the initial render

useEffect(() => {
    if (data.systemBalance) {
      setSystemBalance(data.systemBalance);
    }
}, []); // Empty array means this effect runs once after the initial render

If you want the effect to run whenever data.systemBalance changes, you can include data.systemBalance in the dependency array:

useEffect(() => {
    if (data.systemBalance) {
      setSystemBalance(data.systemBalance);
    }
}, [data.systemBalance]); // This effect runs whenever data.systemBalance changes

useEffect(() => {
    if (data.systemBalance) {
      setSystemBalance(data.systemBalance);
    }
}, [data.systemBalance]); // This effect runs whenever data.systemBalance changes

For more information on how to use the useEffect hook, you can refer to this blog post (https://refine.dev/blog/uselayouteffect-vs-useeffect/) from the Refine documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai open a form only after loading systemBalance

kapa.ai•11mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To open a form only after loading systemBalance, you can use a conditional rendering in React. This means that the form will only be rendered when systemBalance is not null or undefined. Here's an example of how you can do this:

{systemBalance && (
  <Form.Item
    label={{t('pages.marketMaker.addLoan.systemBalance')}}
    name="systemBalance"
  >
    <Input type="string" defaultValue={{systemBalance}} />
  </Form.Item>
)}

{systemBalance && (
  <Form.Item
    label={{t('pages.marketMaker.addLoan.systemBalance')}}
    name="systemBalance"
  >
    <Input type="string" defaultValue={{systemBalance}} />
  </Form.Item>
)}

In this code, the Form.Item component will only be rendered if systemBalance is truthy (i.e., it exists and is not null, undefined, false, 0, NaN, or an empty string). If you want to display a loading indicator while systemBalance is being loaded, you can do something like this:

{systemBalance ? (
  <Form.Item
    label={{t('pages.marketMaker.addLoan.systemBalance')}}
    name="systemBalance"
  >
    <Input type="string" defaultValue={{systemBalance}} />
  </Form.Item>
) : (
  <p>Loading...</p>
)}

{systemBalance ? (
  <Form.Item
    label={{t('pages.marketMaker.addLoan.systemBalance')}}
    name="systemBalance"
  >
    <Input type="string" defaultValue={{systemBalance}} />
  </Form.Item>
) : (
  <p>Loading...</p>
)}

In this code, the text "Loading..." will be displayed while systemBalance is null or undefined. Once systemBalance is loaded, the form will be displayed. For more information on conditional rendering in React, you can refer to the React documentation (https://reactjs.org/docs/conditional-rendering.html). For more information on forms in Refine, you can refer to the Refine documentation (https://refine.dev/docs/api-reference/core/hooks/useForm/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai open a form only after loading systemBalance api

kapa.ai•11mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To open a form only after loading systemBalance from an API, you can use a combination of React's useState and useEffect hooks. First, you would initialize systemBalance with a useState hook and set it to null:

const [systemBalance, setSystemBalance] = useState(null);

const [systemBalance, setSystemBalance] = useState(null);

Then, you would use a useEffect hook to fetch the systemBalance from your API:

useEffect(() => {
  // Fetch systemBalance from your API
  fetchSystemBalance().then(response => {
    // Update systemBalance state with the response
    setSystemBalance(response);
  });
}, []); // Empty array means this effect runs once after the initial render

useEffect(() => {
  // Fetch systemBalance from your API
  fetchSystemBalance().then(response => {
    // Update systemBalance state with the response
    setSystemBalance(response);
  });
}, []); // Empty array means this effect runs once after the initial render

In this code, replace fetchSystemBalance with your actual API call. This useEffect hook will run once after the initial render, fetch the systemBalance from your API, and update the systemBalance state with the response. Finally, you would conditionally render your form based on whether systemBalance is null:

{systemBalance ? (
  <Form.Item
    label={{t('pages.marketMaker.addLoan.systemBalance')}}
    name="systemBalance"
  >
    <Input type="string" defaultValue={{systemBalance}} />
  </Form.Item>
) : (
  <p>Loading...</p>
)}

{systemBalance ? (
  <Form.Item
    label={{t('pages.marketMaker.addLoan.systemBalance')}}
    name="systemBalance"
  >
    <Input type="string" defaultValue={{systemBalance}} />
  </Form.Item>
) : (
  <p>Loading...</p>
)}

In this code, the text "Loading..." will be displayed while systemBalance is null. Once systemBalance is loaded from the API, the form will be displayed. For more information on useState and useEffect, you can refer to the React documentation (https://reactjs.org/docs/hooks-reference.html). For more information on forms in Refine, you can refer to the Refine documentation (https://refine.dev/docs/api-reference/core/hooks/useForm/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@batuhanw @kapa.ai I am setting Form iinput field value where some of the values will be input by user and some are p[refilled, the prefilled values are not part of request

kapa.ai•11mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If you want to include pre-filled values in your form submission, you need to ensure that these values are part of the form's state. In Refine, you can use the useForm hook to manage your form state. Here's an example of how you can do this:

import React from "react";  
import { useForm } from "@refinedev/react-hook-form";  
  
export const UserCreate: React.FC = () => {  
 const {  
 refineCore: { onFinish, formLoading },  
 register,  
 handleSubmit,  
 } = useForm();  
  
 const handleSubmitPostCreate = (values) => {  
 const { name, surname } = values;  
 const fullName = `${name} ${surname}`;  
 onFinish({  
 ...value,  
 fullName,  
 });  
 };  
  
 return (  
 <form onSubmit={handleSubmit(handleSubmitPostCreate)}>  
 <input {...register("name")} />  
 <input {...register("surname")} />  
 </form>  
 );  
};

import React from "react";  
import { useForm } from "@refinedev/react-hook-form";  
  
export const UserCreate: React.FC = () => {  
 const {  
 refineCore: { onFinish, formLoading },  
 register,  
 handleSubmit,  
 } = useForm();  
  
 const handleSubmitPostCreate = (values) => {  
 const { name, surname } = values;  
 const fullName = `${name} ${surname}`;  
 onFinish({  
 ...value,  
 fullName,  
 });  
 };  
  
 return (  
 <form onSubmit={handleSubmit(handleSubmitPostCreate)}>  
 <input {...register("name")} />  
 <input {...register("surname")} />  
 </form>  
 );  
};

In this code, register is a function from the useForm hook that you can spread into an input field to connect it to the form's state. When the form is submitted, the handleSubmitPostCreate function is called with the form's current values. If you want to pre-fill some values, you can do so by setting the defaultValue prop on the input field:

<input {...register("name")} defaultValue="John" />

<input {...register("name")} defaultValue="John" />

In this code, the name input field will be pre-filled with "John". When the form is submitted, "John" will be included in the form's values even if the user doesn't change it. For more information on how to use forms in Refine, you can refer to the Refine documentation (https://refine.dev/docs/api-reference/core/hooks/useForm/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@parothia As bot mentioned, you can use defaultValue. Is that answers your question?

xenial-black•11mo ago

yes
