How to prefetch a specific query with id?
Using invalidate just marks the query invalidated and the new data isn't being loaded when I open the component again. I want to force refetch the query i.e I want to refetch it.

Hi @ethix. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

In Refine, you can use the
refetch
function provided by the data-related hooks to manually refetch data. For example, if you are using the useShow
hook to fetch a specific resource by its ID, you can use the refetch
function as follows:
You can call refetch
whenever you want to force a refetch of the data. This will bypass any caching and fetch fresh data from the server.
If you want to invalidate a specific state of a resource with an ID, you can use the useInvalidate
hook:
This will mark the specified state as invalidated. The next time you fetch this state, it will be fetched from the server instead of from the cache.
Please note that invalidation does not trigger a refetch immediately. It only marks the data as outdated so that it will be refetched the next time it is needed.

@kapa.ai No, after a query is invalidated, it is refetched only when the component is mounted again. I want to force refetch the query, and not invalidate it
Let me check the knowledge base for you. One moment! :books:

Similarly, you can use the refetch

and useForm
:
Please note that calling refetch
will immediately trigger a network request to fetch the data, regardless of whether the data is currently being used or not.

@kapa.ai give me an example of how should I call the refetch function

Sure, here's an example of how you can use the
refetch
function with the useShow
hook in Refine:
In this example, useShow
is used to fetch a specific post with the ID of "1". The refetch
function is then used to manually refetch this data from the server.
You can call refetch
whenever you want to force a refetch of the data. This will bypass any caching and fetch fresh data from the server.

@kapa.ai I tried refetching and logging the new data in console but still, the data is stale
Let me check the knowledge base for you. One moment! :books:
----------------------
The
refetch
function in Refine returns a Promise that resolves to the new data. However, it doesn't immediately update the data
variable in the component. The data
variable will be updated on the next render after the refetch is complete.
If you want to log the new data immediately after refetching, you can do so by awaiting the refetch
function:
In this example, refetch
is called and the returned Promise is awaited. The resolved value (which is the new data) is then logged to the console.
Please note that you need to be inside an async function to use await
. If you're not, you can use the then
method of the Promise instead:
Remember that even though you can get the new data immediately with this method, the data
variable in your component will still only be updated on the next render.

@kapa.ai This is exactly how I checked it.
Let me check the knowledge base for you. One moment! :books:

In your code, you're logging
variant_data
immediately after the refetch
completes. However, variant_data
won't be updated with the new data until the next render. This is why you're still seeing the old data in the console.
If you want to log the new data immediately after the refetch, you should log the result of the refetch
function instead:
In this updated code, refetch
is called and the returned Promise is awaited. The resolved value (which is the new data) is then logged to the console.
Remember that even though you can get the new data immediately with this method, the variant_data
variable in your component will still only be updated on the next render.
