What is the best way to write an admin panel for a web application?

Question

JavaScript

In general, the task is this, I wrote the front-end part of the application in which there are some blocks, with some content, names, paths to pictures, etc., which are taken from the json file using, of course, jquery.

Now I want to make something like an admin panel for this application, in which any user can take and change the contents of the blocks by editing the json file. An approximate concept is this: the
user enters the admin panel, sees the add button, presses it, a certain form appears with fields like "title", "something else", "image name".
He fills it in and everything that he entered into these fields is thrust into the json document as part of an array of one specific block. And thus, he can add the number of elements he needs to these blocks.

As you can see from the tags, I'm looking towards ruby ​​on rails to implement this project, because the framework is very interesting to me. Well, in fact, it would be great to find out from knowledgeable people whether my choice is suitable for this case and in which direction I need to dig to study the things I need in this project.

PS: I know about php, I don’t really want to use it, it’s interesting to dive into the world of rails :)
