I building a simple todo app using the MERN stack with router and able to get it going except the edit part. I have 3 routes, the "Todos" page where i use axios to get the data from my express server route. The "Add" page for create new todo and the "Edit" page for editing and deleting. Here's my todos page where each todo has a button that takes the id as a url parameter unto the Edit page.
That little pencil/paper icon on each todo is a button link that get's the ID on click. Here's my Edit page with the data.
The warning:
Here's my Todos page i'm using a custom hook to fetch the data from express server route:
import React from 'react';
import useGetAPI from '../custom_hooks/useGetAPI';
import Todo from './todo_item/Todo';
const Todos = () =>{
const data = useGetAPI('http://localhost:4000');
return (
<div className="page">
<div className="page-header">
<h1>Todo Lists</h1>
</div>
<div className="page-content">
<ul className="todo-list">
{
data.map((todo)=><Todo todo={todo} key={todo._id}/>)
}
</ul>
</div>
</div>
);
}
export default Todos;
Here's my custom hooks for fetching data - used in Todos.
import {useState,useEffect} from 'react';
import axios from 'axios';
const useGetAPI = (url)=>{
const [data,setData] = useState([]);
useEffect(()=>{
const fetchData = async ()=>{
const response = await axios.get(url);
const data = [...response.data];
const error = response.error;
if(error)
console.log(error)
else{
console.log(data);
setData(data);
}
};
fetchData();
},[url])
return data;
}
export default useGetAPI;
Here's my Edit Page

const responseData = useGetApiWithParams('http://localhost:4000/edit',todoID);
console.log(`Todo id: ${todoID}`);
/* Set default data from database */
useEffect(()=>{
setTodo(responseData);
},[responseData,setTodo]);
const [description,setDescription] = useState('');

console.log(`Description ${description}`);

const updatedTodo = {
description,

priority,
completed: false
}
axios.put(`http://localhost/4000/edit/${props.match.params.id}`, updatedTodo)
.then(res=>console.log(res.data))

console.log(error);

Here's my custom hook for fetching data based on the Todo ID i get from the url:
import { useState,useEffect } from 'react';
import axios from 'axios';
const useGetApiWithParams = (url,params)=>{
const [data,setData] = useState([]);
useEffect(()=>{
const fetchData = async ()=>{
const response = await axios.get(`${url}/${params}`);
const data = response.data;
const error = response.error;
if(error)
console.log(`Error: ${error}`)
else{
console.log(...data);
setData(...data);
}
};
fetchData();
},[url,params])
return data;
}
export default useGetApiWithParams;
And the url with id param from MongoDB:
How to solve this? I tried the placeholder and set it's value to the response data from api but it only works for text boxes, what about the radio buttons and checkboxes? They don't seem to set the default value. For example the radio button for setting the priority value={responseData.priority} doesn't set the value as you can see here:
What i would like to happen is: from the Todos page on clicking the edit button, the edit page with a form already filled with values based on the todo id from the url parameter and be able to edit the values as well. Need help, thanks!
