I want to build a dashboard for a blog. I have a page, listing all blog posts using a component for each list item. Now, inside each list item, I have a button to delete the post.
So far, everything is working. The post gets deleted, and if I reload the page, it is gone from the list. But I can’t get it to re-render the page automatically, after deleting a post. I kind of cheated here using window.location.reload()
but there has to be a better way?
This is my Page to build the list of all Posts
import {
CCol,
CContainer,
CRow,
CTable,
CTableHead,
CTableRow,
CTableHeaderCell,
CTableBody,
} from "@coreui/react";
import { useState, useEffect } from "react";
import DashboardSidebar from "../../components/dashboard/Sidebar";
import { getAllBlogPosts } from "../../services/blogService";
import BlogListItem from "../../components/dashboard/blog/BlogListItem";
import "./Dashboard.scss";
const AdminBlogListView = () => {
const [blogposts, setBlogposts] = useState([]);
useEffect(() => {
getBlogPosts();
}, []);
async function getBlogPosts() {
const response = await getAllBlogPosts();
setBlogposts(response.data);
}
// console.log(blogposts);
return (
<div className="adminContainer">
<div className="adminSidebar">
<DashboardSidebar />
</div>
<div className="adminContent">
<CContainer fluid>
<CRow className="mb-3">
<CCol>
<CTable>
<CTableHead>
<CTableRow>
<CTableHeaderCell scope="col">#</CTableHeaderCell>
<CTableHeaderCell scope="col">Titel</CTableHeaderCell>
<CTableHeaderCell scope="col">Content</CTableHeaderCell>
<CTableHeaderCell scope="col"></CTableHeaderCell>
</CTableRow>
</CTableHead>
<CTableBody>
{blogposts.map((post) => {
return <BlogListItem key={post._id} post={post} />;
})}
</CTableBody>
</CTable>
</CCol>
</CRow>
</CContainer>
</div>
</div>
);
};
export default AdminBlogListView;
And this is the BlogListItem Component
import { useState, useEffect } from "react";
import {
CTableRow,
CTableHeaderCell,
CTableDataCell,
} from "@coreui/react";
import CIcon from "@coreui/icons-react";
import * as icon from "@coreui/icons";
import {
deleteBlogPost,
getBlogPostById,
// updateBlogPost,
} from "../../../services/blogService";
import { useNavigate } from "react-router-dom";
const BlogListItem = (props) => {
const id = props.post._id;
const [visible, setVisible] = useState(false);
const [post, setPost] = useState({
title: "",
content: "",
});
useEffect(() => {
getBlogPostById(id)
.then((response) => setPost(response.data))
.catch((error) => console.log(error));
}, []);
const handleDelete = async (event) => {
event.preventDefault();
const choice = window.confirm("Are you sure you want to delete this post?");
if (!choice) return;
await deleteBlogPost(post._id);
window.location.reload();
};
return (
<>
<CTableRow>
<CTableHeaderCell scope="row">1</CTableHeaderCell>
<CTableDataCell>{post.title}</CTableDataCell>
<CTableDataCell>{post.content}</CTableDataCell>
<CTableDataCell>
<CIcon
icon={icon.cilPencil}
size="lg"
onClick={() => setVisible(!visible)}
/>
<CIcon
icon={icon.cilTrash}
className="deleteButton"
size="lg"
color=""
onClick={handleDelete}
/>
</CTableDataCell>
</CTableRow>
</>
);
};
export default BlogListItem;
What can I do instead of window.location.reload()
to render the AdminBlogListView
after deleting an item? I tried using useNavigate()
but that doesn’t do anything
Thanks in advance 🙂
