Topic: MDBDatatable not updating new rows per useState

Bridget Melvin premium asked 2 years ago


*Expected behavior*I have a rather complicated set of HOC and a CompaniesTable component with state data that is properly reflecting when a new Company object is added to the array. I expected the datatable to update for new rows but it does not.

*Actual behavior*The datatable never re-renders for new data.

Resources (screenshots, code snippets etc.)

CompaniesTable.js

import React, { useState, useEffect } from 'react';
import { Link } from 'react-router-dom';

  }, [companies])

  const setLastCompany = (newCompanyName) => {
    const prevCompany = companies.rows.filter(entry => entry.last === true)[0]
    let newCompany = prevCompany

    if (prevCompany.name !== newCompanyName) {
      prevCompany.last = false;

You probably are not using useEffect hook correctly. Please check again, if the actionData changes properly.


Bridget Melvin premium commented 2 years ago

what am I doing wrong?


Bridget Melvin premium commented 2 years ago

I tried updating it to ....

useEffect(() => { console.log('useEffect CompaniesTable.js', companies) setActionData(prevState => ({ ...prevState, rows: addActionButtons(companies.rows) })) }, [companies])

but it still does not work


Bridget Melvin premium commented 2 years ago

I got it to work - nothing with useEffect
