Sep 6-13 Oct - Deploy Railway - CSRF Laravel BEWARE - AI DOESN'T dominate you - Flask FREE +

▶

Welcome to another week. I'm going to talk about all the content uploaded between October 6 and 13, which is the current date.

Community Versions and Training

Starting as always with the community versions: we already have 10 to date, plus the Flash versions, which has over 70 pages. With these, you can start creating your projects in this technology, learn its basis or fundamentals, and develop a small CRUD that includes handling controllers and databases.
These are the initial three or four chapters, completely free.

Progress in the Django Online Store

It's also worth remembering that the Django online store application is now completely functional.
This week I've mostly worked on the Laravel one, replicating some changes I made in this course and book.
I also released the introductory video for the Django online store course, where I explain exactly what we are going to build.

Content on YouTube and the blog

Moving on to YouTube and blog content, this week I published about the CSRF token in Laravel. Depending on how you configure it, it may only work in development.
For example, if you make an HTTP request using JavaScript and you're not authenticated in production, it might fail.
It happened to me during registration: it worked perfectly locally, but in production, when moving the application to the domain, the request was blocked if the user was not authenticated.
You have the video and the full publication for more details.

Trends: Python vs JavaScript

Regarding Python, it's rising—to no one's surprise—while JavaScript is falling.
This is due, in part, to the rise of AI coding. However, nothing is perfect: Python is slower than other solutions.
Each language has its advantages and disadvantages, and I mention this briefly in the article.

Refactoring the payment controller in Laravel

I also published a video from the Laravel LWER course, where we refactored a payment controller.
Remember that there are two stores: one for books and one for generic products.
Both have a payment gateway, listings, and similar behaviors, so we modularized the code as much as possible.

We created a central controller that receives a generic item (be it a book or product), avoiding code duplication.

Opinion: AI as a tool

Another opinion video: AI should be a tool, not the one who directs the project.
You are the pilot, the AI simply assists. I share a personal anecdote about it in the video and the post.

Payment gateway in Django

I also published a summary of the payment gateway in Django, for the course mentioned earlier.
I explain the layers created:

• The abstract model.
• Specific models.
• Classes that process payments with Stripe and PayPal.
• A class that decides which gateway to charge with.
• And finally the detail view with the product (book or generic).
• Additionally, we configured smart routes and helper methods.

Demo mode for applications

I also showed how to create a demo of your application, in both Laravel and Django.
In this version, I block certain options and display information when the system is in demo mode.
This is achieved by creating an environment variable and using it in middleware or conditionals.

Laravel Livewire Store Course/Book

To conclude, the introductory video for the tenth community book.
This week I paused the Django course to focus on Laravel LWER, applying the modularization changes I already implemented in the Django book.

We created abstract product classes, refactored the payment gateway, and improved the structure to make everything cleaner, more scalable, and less error-prone.
We also added demo mode, custom titles, and visual details like flags in the titles.
