What hook to use for simple array of strings
Hi, I created a resource called "Media" (its ment to be a media library). Now on the list page I want to display a grid of images, these image sources are the response of the request, its just a simple array with image urls (strings).
What hook should I use to get all the images?

Hi @BlackBearFTW. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
You can use the
useList
hook from Refine to fetch a collection of resources. In your case, you can use it to fetch your "Media" resource which contains the array of image URLs. Here's an example of how you can use it:
In this example, data
will contain the array of image URLs that you can then use to display your grid of images.
For more information, you can refer to the useList documentation (https://refine.dev/docs/api-reference/core/hooks/data/useList/).

@kapa.ai how can I now display these images in a grid (all images need to be the same size, so use image: cover)
Let me check the knowledge base for you. One moment! :books:

You can use the Ant Design's Grid system to display the images in a grid format. Here's an example of how you can do it:
In this example, we're using Ant Design's
Row
and Col
components to create a grid. Each image is displayed in a Col
with a span of 6, meaning there will be 4 images per row. The Image
component is used to display each image, with a width and height of 200 pixels. The objectFit: 'cover'
style is used to ensure that the image covers the entire area of the Image
component, cropping it if necessary.
Please note that you need to adjust the span
value and the width
and height
values according to your needs.
For more information, you can refer to the Ant Design Grid system documentation (https://ant.design/components/grid/) and the Ant Design Image component documentation (https://ant.design/components/image/).

@kapa.ai data still needs to be a base record...., it shouldn't be
Let me check the knowledge base for you. One moment! :books:
----------------------
In Refine, the
useList
hook is designed to work with a collection of resources where each resource is a BaseRecord
. A BaseRecord
is an object with an id
field and any number of additional fields. This is the standard way Refine handles data.
However, in your case, since you're dealing with an array of strings (image URLs), you might need to adjust your data structure to fit into the BaseRecord
format. One way to do this could be to map your array of strings to an array of objects, where each object has an id
and a url
field. Here's an example:
Now data
is an array of BaseRecord
objects that you can use with useList
.
If you have control over your backend, you might consider adjusting your API to return data in this format. If not, you can perform this transformation on the frontend after you receive the API response.
For more information, you can refer to the BaseRecord interface reference (https://refine.dev/docs/core/interface-references#baserecord).

@kapa.ai no I need to get these urls from my dataprovider
Let me check the knowledge base for you. One moment! :books:
----------------------
In that case, you would need to implement a custom method in your data provider to fetch the array of image URLs. Refine's data providers support custom methods that you can use for non-standard API operations.
Here's an example of how you might define such a method in your data provider:
In this example,
getMedia
is a custom method that fetches the array of image URLs from the /media
endpoint, and transforms it into an array of BaseRecord
objects.
You can then use the useCustom
hook in your component to call this custom method:
In this example, data
will contain the array of BaseRecord
objects that you can use to display your grid of images.
For more information, you can refer to the Custom Methods documentation (https://refine.dev/docs/data/data-provider#custom-methods) and the useCustom hook documentation (https://refine.dev/docs/api-reference/core/hooks/data/useCustom/).
