HandleSave mutate useUpdate & useOne
I want to update and use useOne in the same handleSave code. When I put useOne inside the handleSave it dont work.
The code is:
const { mutate } = useUpdate<IProdutos, HttpError>();
const handleSave = async (value: any ) => { const { data } = useOne<IProdutos, HttpError>({ resource: "rqp-produtos", id: value.rqp_produto_id.id, }); const product = data?.data;
mutate({ resource: "rqp-produtos", id: value.rqp_produto_id.id, values: { stock: product?.stock , }, mutationMode: "optimistic", invalidates: [], successNotification: false, errorNotification: false, });
formProps.onFinish?.({ rqp_requisicao_id: value.rqp_requisicao_id, rqp_produto_id: value.rqp_produto_id.id,
qnt: product?.stock, }); };
const { mutate } = useUpdate<IProdutos, HttpError>();
const handleSave = async (value: any ) => { const { data } = useOne<IProdutos, HttpError>({ resource: "rqp-produtos", id: value.rqp_produto_id.id, }); const product = data?.data;
mutate({ resource: "rqp-produtos", id: value.rqp_produto_id.id, values: { stock: product?.stock , }, mutationMode: "optimistic", invalidates: [], successNotification: false, errorNotification: false, });
formProps.onFinish?.({ rqp_requisicao_id: value.rqp_requisicao_id, rqp_produto_id: value.rqp_produto_id.id,
qnt: product?.stock, }); };

Hi @Sly. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
The issue you're facing is due to the incorrect usage of the
useOne
hook. Hooks in React should be called at the top level of your React function, not inside a function or a callback. This is a rule of hooks in React.
Here's how you can refactor your code:
In this refactored code, useOne
is called at the top level of your function, not inside handleSave
. This way, you're adhering to the rules of hooks and should not face any issues.
For more information, you can refer to the documentation for useOne
(https://refine.dev/docs/data/hooks/use-one) and useUpdate
(https://refine.dev/docs/data/hooks/use-update).

@kapa.ai its not recognising the "value":
const { data } = useOne<IProdutos, HttpError>({
resource: "rqp-produtos",
id: value.rqp_produto_id.id,
Let me check the knowledge base for you. One moment! :books:
----------------------
The
value
object is not recognized because it's not in the scope where you're trying to use it. You're trying to use it in the useOne
hook which is outside the handleSave
function where value
is defined.
To solve this, you can use a state variable to store the id
and update it whenever handleSave
is called. Here's how you can do it:
In this refactored code, we're using a state variable id
to store the id
from value
. We update this id
state variable inside handleSave
function. This way, the useOne
hook will have access to the correct id
value.

@kapa.ai stil having "id" error
Let me check the knowledge base for you. One moment! :books:
----------------------
I see, it seems like the
useOne
hook is not re-rendering when the id
state changes. This is because hooks in React are not reactive to changes in their dependencies like in some other frameworks.
To solve this, you can use the useEffect
hook to call useOne
whenever the id
changes. Here's how you can do it:
In this refactored code, we're using a useEffect
hook to call useOne
whenever the id
changes. We're also using a new state variable product
to store the product data from useOne
. This way, the useOne
hook will be called with the correct id
value whenever id
changes.
Please note that this is a workaround and might not be the most optimal solution. It would be best to restructure your code in a way that you don't need to call a hook inside a callback or a function.

@kapa.ai I get this error:
Argument of type 'IProdutos | undefined' is not assignable to parameter of type 'SetStateAction<IProdutos | null>'.
Let me check the knowledge base for you. One moment! :books:
----------------------
The error message is indicating that the
data
returned from useOne
hook can be undefined
, but the setProduct
function is expecting either an IProdutos
object or null
.
To fix this, you can provide a fallback value (null
) when setting the state:
This way, if data?.data
is undefined
, null
will be used as a fallback.

@kapa.ai Can I use useUpdate to show the current value before update?
Let me check the knowledge base for you. One moment! :books:
----------------------
Yes, you can use the
useOne
hook to fetch the current value of the record before updating it with useUpdate
. Here's a basic example:
In this example, useOne
is used to fetch the current value of the record. You can then use mutate
from useUpdate
to update the record.
Please replace "your-id-here"
and // your updated values here
with your actual id and updated values.
For more information, you can refer to the documentation for useOne
(https://refine.dev/docs/data/hooks/use-one) and useUpdate
(https://refine.dev/docs/data/hooks/use-update).
