Quizz 4 - Rails

Q1 - How do you create a Rails app?

rails new NOM_DE_L_APP
rails new NOM_DE_L_APP --webpack
rails new NOM_DE_L_APP --database=postgres

Turbolinks

Turbolinks is a JavaScript library that intercepts all clicks on <a> links and makes that request via AJAX. It then merges the <head> and replaces the current page <body> with the new body from the AJAX HTML response.

The promise:

Get the performance of a single-page application without the added complexity of a client-side JavaScript framework

Features:

Week 10 / Land your 1st dev job

You can review too!

So you want to become a junior developer Reviewing is not a CTO only privilege. What if we asked you to review this aspiring developer ?

We provide a Rails and the student has to:

Refactor routes

Use NVM (node version manager) like we use rbenv for Ruby

First we will remove node and yarn

brew uninstall yarn
brew uninstall node  
brew uninstall node@8

Lead TA on Le Wagon part-time

Here is a list of guidelines you should follow during a part-time session:

1) Introduce the staff of the day for each session

This is the best way to kickstart the session and have everyone concerned and motivated.

2) You are the referrer for students

Students should know they can report any problem to you.

🎄 Garden and Plants 🎄

This is an optional exercice for the batch 301 during christmas holidays 🎅
