hello friends I have a problem in an application in react JS that is driving me crazy and I don't know how to solve it, I am making a call with axios to obtain information which I have already tried with postman and the backend works perfectly the issue is that I don't know this executing the useEffect() where I am making that call to fill a useState and pass that object by props to a child component. below sent code and error . thank you very much for any help you can give me I'm starting with react

import React, { Fragment, useState, useEffect } from 'react';
import Breadcrumb from '../../common/breadcrumb';

import InfoGeneralQueja from './components/InfoGeneralQueja'
import InfoCalidadQueja from './components/InfoCalidadQueja'
import InfoDirectorQueja from './components/InfoDirectorQueja'

import axios from "axios";
import { useNavigate, useParams } from "react-router-dom";






const QuejaDetalle = () => {
    const [detalle, setDetalle] = useState([])
    //id params
    const { id } = useParams()
    console.log("ID: ", id)

    //User
    const user = JSON.parse(localStorage.getItem('user'))

    //end point
    const endpoint = 'http://localhost:5000/detalle/'

    //Data
    const getQuejaById = async () => {
        const res = await axios.get(endpoint   id)
        .then(function (response) {
            setDetalle(JSON.stringify(response.data))
         }).catch(function (error) {
            console.log(error.response);
        });
        
    }
    //Triggered
    useEffect(() => {getQuejaById()},[])
   



    return (
        <Fragment>
            <Breadcrumb title={`Detalles Evento`} parent="Quejas" />
            <div className="container-fluid"></div>
            <div className="row">
                <InfoGeneralQueja quejaData={detalle} />
                <InfoCalidadQueja quejaData={detalle} user={user} />
                <InfoDirectorQueja quejaData={detalle} user={user} />
            </div >
        </Fragment >
    )
}

export default QuejaDetalle

CodePudding user response:

Your error's stack shows that you're calling .toString() in <InfoGeneralQueja /> on an undefined value. You need to properly handle the detalle prop before it's populated by the effect.

Do not use await and .then. These do the same thing in purpose. It might cause problems like this one.

    const getQuejaById = async () => {
      try {
        const res = await axios.get(endpoint   id)
        setDetalle(JSON.stringify(res.data)) 
      } catch (e) {
        console.error(e)
      }       
    }

Also, you need to ensure that you're getting the data you want from the API.

CodePudding user response:

Thank you very much for your answers, I was able to solve it by conditioning the rendering since it was actually rendering before making the API call

{detalle.length>0 && <InfoGeneralQueja detalle={detalle} />}
            {detalle.length>0 && <InfoCalidadQueja detalle={detalle} user={user} />}
            {detalle.length>0 &&  <InfoDirectorQueja detalle={detalle} user={user} />}
