Datatables Example Table Custom Column Render

Column render in Datatables is use to display column data with special formatting, maybe you want to add some currency format, maybe you want to cut the string if it's too long, etc. If you are a fans of Datatables and don't know how to do custom column render, here's how.

$("#datatable").DataTable({
    dom: "Bfrtip",
    buttons: [
        "copy", "csv", "excel", "pdf", "print"
    ],
    "aoColumnDefs": [
        {
            "render": function ( data, type, row ) {
                return data+ " - TEST" ;
            },
            "targets": [4]
        }
    ],
    "processing": true,
    "serverSide": true,
    "ajax" : "http://localhost/data",
});

So as you can see the codes above, aoColumnDefs property is the one responsible for column render. The render property will provide you with (data, type and row), you can do console.log to print  what the data is being sent by Datatables.

The targets property is the index of column you want to do custom render in it. And property ajax: http://localhost/data should be your web service to provide the data you want to display on the table

Using Datatables JavaScript library has been really great thing in the past, now people start using React as their Front end framework, and the awesomeness of Datatables is now started to deteriorate. I still use this library heavily for my company i work, because they are slow to adapt to new technology.

Actually there's React Datatables you can use from Mdbootstrap here's the link https://mdbootstrap.com/docs/react/tables/datatables/. You can use that React component, but this is not official from Datatables owner. They don't provide the custom column render API i think as the time of this post is published.

MySQL and MariaDB password As already mentioned in the title of this blog, this error message sometimes occurred when we are trying to update our root password database, either MySQL or MariaDB, The error says: ERROR 1348 (HY000): Column 'Password' is not updatable This is because if we use this SQL command to update our database root password, and it turn out to be Restricted by MySQL to use update on mysql database. UPDATE mysql.user SET Password=PASSWORD('1234') WHERE User='root'; The solutions for MySQL Error1348 So you can not update a user password using Update commands, to update the password, use ALTER commands instead. like the following. ALTER USER 'root'@'localhost' IDENTIFIED BY '1234'; And then you need to do the flush privileges to commit previous queries (that alter command above) into the system, simply do like this. flush privileges; So now you have your root with password 1234. Although it is recommended to...

Spring Boot is a handy tool that simplifies the development of Spring Framework applications by reducing the need for cumbersome configuration. In this tutorial, I'll guide you through creating a Spring Boot application using the Netbeans IDE. While you can certainly create a Spring Boot application in Netbeans manually, it's much easier with a plugin designed for Spring development. Here's a step-by-step guide to get you started: 1. Install the Spring Boot Plugin: Open Netbeans and navigate to the Tools menu. Click on "Plugins." Once the Plugins window opens, select the "Available Plugins" tab. Look for the "Nb SpringBoot" plugin, then install and activate it. 2. Create a New Spring Boot Project: After restarting Netbeans IDE, you can create a new project with Spring Boot. Go to File > New Project. Under Categories, select Maven, then choose "Spring Boot Basic." 3. Add Dependencies: With your new project created, open the po...

Spring Kafka - How to use ReplyingKafkaTemplate send and reply synchronously

Microservice Spring with Apache Kafka Today, I want to share how to use Kafka. It's quite interesting once you get the hang of it, and I hope my explanation will make it a bit easier for you. So, Kafka is primarily known as an asynchronous messaging queuing system. This means it allows different parts of your application to communicate with each other without waiting for immediate responses. However, there are times when you might need a more immediate reply from another service in your project. Luckily, Kafka can handle this too. Here’s how it works: The client side sends a message to the server side via Kafka. This message includes a special identifier in the Kafka header request, known as KafkaHeaders.CORRELATION_ID, along with a topic where the server should respond. The server, after processing the request, sends a message back to the same topic with the same correlation ID. This way, the client knows that the message is a response to its initial request and can act accordingl...
