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.

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

open a form only after loading systemBalance
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:
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:
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/).

@kapa.ai
open a form only after loading systemBalance api
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
:
Then, you would use a useEffect
hook to fetch the systemBalance
from your API:
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
:
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/).

Hello @parothia could you describe your problem with more details? Ideally give us a reproducible example and some description of what you are trying to achieve. Help bot can't help with no context.

@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
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:
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:
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/).

@parothia As bot mentioned, you can use defaultValue. Is that answers your question?
quickest-silverOP•16mo ago
yes
