Component creation. Why doesn't work?

[astatonn]

Hello everyone,

I'm trying to develop my own component, however, I'm encountering difficulties in understanding how to create it.
I have already read the FAQ on component creation, the J4.x component creation article, searched the internet, asked Gemini and ChatGPT, but I can't make progress. :(

My project structure is as follows:

administrator/components/com_aniversariantes/services/provider.php
administrator/components/com_aniversariantes/sql/install.mysql.utf8.sql
administrator/components/com_aniversariantes/src/Controller/DisplayController.php
administrator/components/com_aniversariantes/src/view/HtmlView.php
administrator/components/com_aniversariantes/tmpl/aniversariantes/default.php
administrator/components/com_aniversariantes/aniversariantes.xml
components/com_aniversariantes/src/Controller/DisplayController.php
components/com_aniversariantes/view/Aniversariantes/HtmlView.php
components/com_aniversariantes/tmpl/aniversariantes/default.php

At this moment, I can display static data in a datatable on my component's admin panel.

What do I want?
I need to code a CRUD for the table that I created and send data to the component to display it on the site section.

I don't want someone to develop my component. I just want to fix the problems I'm encountering and understand how to complete my task.

I would really appreciate it if someone could spare their time to show me a way to solve this because I don't have anyone to do it for me at the moment.

@astatonn , Good for you for starting component development, but you have more research to do.

The J! documentation will take you further on that you currently are. There's a J4! basic documentas well as Robbie's excellent in-depth J3 article with J4 additions.

In short, you need to use a model.

[chmst]

Please be aware that a tutorial for J3 is not at all suitable for J4/5.
Newer documentation for developers will be published here https://manual.joomla.org/

@chmst am also interested in developing modules, thats why Im asking. When will the docs be published?
