react hooks. hasMore does not work well.

[johnvonneumann7]

api server: django If res.data.next is null, I want to disable the next reload, but the following code will disable it after one round, and if the page has up to 3, it will get up to 4, and I will get a 404 error.

import React, { useState } from 'react';
import InfiniteScroll from 'react-infinite-scroller';
import axios from 'axios';
import Box from '@material-ui/core/Box';
import Grid from '@material-ui/core/Grid';
import CircularProgress from '@material-ui/core/CircularProgress';
import { Video } from '../components/Types';
import VideoCard from '../components/VideoCard';

type Props = {
  to: string;
  tag?: string;
};

export default function VideoList(props: Props) {
  const [data, setData] = useState<Video[]>([]);
  const [hasMore, setHasMore] = useState(true);

  const loadMore = (page: number) => {
    axios
      .get(`/api/videos/${props.to}`, {
        params: { page: page, tag: props.tag },
      })
      .then((res) => {
        setData([...data, ...res.data.results]);
        if (!res.data.next) setHasMore(false);
      });
  };

  return (
    <InfiniteScroll
      pageStart={0}
      loadMore={loadMore}
      hasMore={hasMore}
      loader={
        <Box key={0} textAlign="center">
          <CircularProgress />
        </Box>
      }
    >
      <Grid container spacing={2}>
        {data.map((video) => (
          <Grid key={video.pk} item xs={12} sm={6} md={4} lg={3} xl={2}>
            <VideoCard video={video} />
          </Grid>
        ))}
      </Grid>
    </InfiniteScroll>
  );
}

What should I do in this case?

I would recommend using react-query with the function Inifinity Query. I use that package with this package and it's work properly.

You may just have to call setHasMore before you call setData
