pagination chakra ui inference

Is there any suggestion how to give the proper data structure from backend so that the inference will render a nicely pagination navigation at the bottom?

Hi @mfarhanzachary. 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 extracts provided do not contain specific information on how to structure data from the backend for pagination with Chakra UI inference in refine. However, refine does provide a useTable hook that can be used for pagination, as mentioned in this blog post (https://refine.dev/blog/handcrafted-nextjs-e-commerce-app-tutorial-strapi-chakra-ui#adding-pagination). For more detailed information, you might find the refine documentation (https://refine.dev/docs) helpful. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

are chkara ui inferencer expect pagination at the back end or it's expect to do pagination at the front end? @kapa.ai

Let me check the knowledge base for you. One moment! :books: ---------------------- The extracts provided do not specify whether Chakra UI in the context of refine expects pagination to be handled at the backend or the frontend. However, the usePagination hook from @refinedev/chakra-ui package is used in the frontend to handle pagination controls. This hook accepts pagination values from the useTable hook. Here's an example of how it's used in a Pagination component:

import React from "react";
import { HStack, Button, Box } from "@chakra-ui/react";
import { IconChevronRight, IconChevronLeft } from "@tabler/icons";
import { usePagination } from "@refinedev/chakra-ui";

import { IconButton } from "@chakra-ui/react";

type PaginationProps = {
 current: number;
 pageCount: number;
 setCurrent: (page: number) => void;
};

export const Pagination: React.FC<PaginationProps> = ({
 current,
 pageCount,
 setCurrent,
}) => {
 const pagination = usePagination({
 current,
 pageCount,
 });

 // ... rest of the component
};

import React from "react";
import { HStack, Button, Box } from "@chakra-ui/react";
import { IconChevronRight, IconChevronLeft } from "@tabler/icons";
import { usePagination } from "@refinedev/chakra-ui";

import { IconButton } from "@chakra-ui/react";

type PaginationProps = {
 current: number;
 pageCount: number;
 setCurrent: (page: number) => void;
};

export const Pagination: React.FC<PaginationProps> = ({
 current,
 pageCount,
 setCurrent,
}) => {
 const pagination = usePagination({
 current,
 pageCount,
 });

 // ... rest of the component
};

This suggests that pagination is handled on the frontend, but it doesn't rule out the possibility of backend pagination. For more specific details, you might want to refer to the refine documentation (https://refine.dev/docs). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

but my inferenced code doesn't do the pagination. it show the button at the bottom correctly. i send 70 data and it shows 7 page. but all 70 data is showed at every page. @kapa.ai

Let me check the knowledge base for you. One moment! :books: ---------------------- It seems like your frontend is correctly setting up the pagination controls, but the data isn't being paginated correctly. This could be due to the way your backend is handling the data. In refine, the useTable hook is used for pagination and it expects the backend to handle the pagination of data. When you click on a page number, a request is sent to the backend with parameters indicating the page number and the number of items per page. The backend should then respond with the appropriate subset of data for that page. Here's an example of how you might set up the useTable hook with pagination:

const { tableProps, paginationProps } = useTable({
    resource: "posts",
    initialSorter: [{ field: "title", order: "asc" }],
    initialFilters: [{ field: "status", operator: "eq", value: "published" }],
    pagination: { total: 70, pageSize: 10, current: 1 },
});

const { tableProps, paginationProps } = useTable({
    resource: "posts",
    initialSorter: [{ field: "title", order: "asc" }],
    initialFilters: [{ field: "status", operator: "eq", value: "published" }],
    pagination: { total: 70, pageSize: 10, current: 1 },
});

In this example, paginationProps is an object that contains the current page number, the total number of items, and the number of items per page. This object is passed to your Pagination component to display the correct pagination controls. If your data is not being paginated correctly, it could be that your backend is not correctly interpreting the pagination parameters sent in the request, or it's not correctly slicing the data into pages. You might need to check your backend implementation to ensure it's correctly handling pagination. For more information, you can refer to the useTable documentation (https://refine.dev/docs/data/hooks/use-table#pagination). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

show me how the data should handled in bakcend to give proper pagination @kapa.ai

kapa.ai•7mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The backend should handle pagination by interpreting the page and pageSize parameters from the request, and then returning the appropriate subset of data. Here's a basic example of how you might do this in a Node.js Express server:

app.get('/data', (req, res) => {
    const page = parseInt(req.query.page);
    const pageSize = parseInt(req.query.pageSize);

    // Get the appropriate subset of data
    const data = allData.slice((page - 1) * pageSize, page * pageSize);

    res.json(data);
});

app.get('/data', (req, res) => {
    const page = parseInt(req.query.page);
    const pageSize = parseInt(req.query.pageSize);

    // Get the appropriate subset of data
    const data = allData.slice((page - 1) * pageSize, page * pageSize);

    res.json(data);
});

In this example, allData is the entire dataset. The slice method is used to get the subset of data for the requested page. The first item on the page is at index (page - 1) * pageSize, and the last item is at index page * pageSize. This is a very basic example and your actual implementation might be more complex, especially if you're using a database. But the key idea is the same: use the page and pageSize parameters to determine which subset of data to return. For more information on how to handle pagination in refine, you can refer to the useTable documentation (https://refine.dev/docs/data/hooks/use-table#pagination). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

but when i check in req.query its sending this { _end: '10', _start: '0' } @kapa.ai how to handle pagination with that when i am using prisma

kapa.ai•7mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The _start and _end parameters in the request query are used by refine to handle pagination. _start is the starting index of the data for the current page, and _end is the ending index. When using Prisma, you can handle pagination using the skip and take options in your queries. skip is the number of records to skip (equivalent to _start), and take is the number of records to take (equivalent to _end - _start). Here's an example of how you might do this:

const { _start, _end } = req.query;

const data = await prisma.post.findMany({
  skip: Number(_start),
  take: Number(_end) - Number(_start),
});

const { _start, _end } = req.query;

const data = await prisma.post.findMany({
  skip: Number(_start),
  take: Number(_end) - Number(_start),
});

In this example, post is the model you're querying. Replace it with the appropriate model for your data. Remember to convert _start and _end to numbers before using them, as they are sent as strings in the request query. For more information on pagination with Prisma, you can refer to the Prisma documentation (https://www.prisma.io/docs/concepts/components/prisma-client/pagination). For more information on how refine handles pagination, you can refer to the useTable documentation (https://refine.dev/docs/data/hooks/use-table#pagination). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
