Update Project

Code Changes

Let’s update the code and deploy again. We’ll add a puts "debug 1".


class PostsController < ApplicationController
  before_action :set_post, only: %i[ show update destroy ]

  # GET /posts
  def index
    puts "debug 1" # <= ADD THIS LINE
    @posts = Post.all

  # ....

Deploy Again

To deploy again run jets deploy.

❯ jets deploy

Jets Logs

You can also use the jets logs command to tail the logs in your terminal.

❯ jets logs -f

Note: The jets logs command use the controller Lambda Function Log Group, IE: /aws/lambda/rails-dev-controller by default, so we do not have to specify the -n option.

Next, we’ll delete the project.
