Hi @Sly. 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 information extracts provided do not contain specific details on how to generate an ascending number on each create and start from 1 on every new year using refine or Ant Design System.
However, refine provides a lot of out-of-the-box functionality for rapid development and it ships with Ant Design System, an enterprise-level UI toolkit. You might find more information in the refine documentation (https://refine.dev/docs) or Ant Design documentation (https://ant.design/docs/react/introduce).

@kapa.ai how to select count ID?
Let me check the knowledge base for you. One moment! :books:
----------------------
The information extracts provided do not contain specific details on how to select or count IDs using refine or Ant Design System.
However, in refine, you can use hooks like
useSelect
to interact with your data. Here's an example of how you might use it:
In this example, useSelect
is used to fetch categories from a resource and display them in a select box. The options
returned by useSelect
is an array of objects, each representing a category. You can count the number of IDs (or categories) by checking the length of this array.
For more detailed information, you might find the refine documentation (https://refine.dev/docs) helpful.

@kapa.ai How to count the number of IDs by checking the length of this array?
Let me check the knowledge base for you. One moment! :books:
----------------------
In JavaScript, you can use the
length
property of an array to get the count of its elements. If you have an array of IDs, you can simply use array.length
to get the count.
Here's an example:
In the context of the useSelect
hook in refine, if you want to count the number of options (which could be IDs), you can do:
In this example, options.length
gives you the count of options returned by useSelect
. Please note that options
can be undefined
if the data is still being fetched or if an error occurred, hence the conditional (options ? options.length : 0
).

@kapa.ai How to do this in typescript?
Let me check the knowledge base for you. One moment! :books:
----------------------
The examples provided above are already in TypeScript. TypeScript is a superset of JavaScript, which means any valid JavaScript code is also valid TypeScript code.
Here's the TypeScript version of the array length example:
And here's the TypeScript version of the
useSelect
hook example in refine:
In these examples, number[]
is a TypeScript type annotation that indicates ids
is an array of numbers, and number
indicates count
is a number. The ICategory
interface is a TypeScript feature used to define the shape of an object.
