miligraf

CI/CD for static assets and Lambda function

This Gist is based on Building a continuous delivery pipeline for a Lambda application with AWS CodePipeline

What happened?

Needed to build a NodeJS project, upload the static assets to an S3 bucket and also deploy a small Lambda function that lived in a subfolder.

Prerequisites

Aws.config.update({
  region: 'us-east-1',
  credentials: Aws::Credentials.new(ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY'])
})

S3_BUCKET = Aws::S3::Resource.new.bucket(ENV['S3_BUCKET'])

@post = S3_BUCKET.presigned_post(key: "uploads/#{SecureRandom.uuid}/${filename}", success_action_status: '201', acl: 'public-read')

post = Aws::S3::Resource.new.bucket("fake").presigned_post(key: "uploads/#{SecureRandom.uuid}/${filename}", success_action_status: '201', acl: 'public-read')

  def self.column(name, sql_type = nil, default = nil, null = true)
    columns << ActiveRecord::ConnectionAdapters::Column.new(
      name.to_s,
      default,

class RenameReadColumToState < ActiveRecord::Migration
  def change
    add_column :messages, :state, :integer, default: 0

    execute "UPDATE messages SET state = CAST(read AS INTEGER);"

    remove_column :messages, :read
  end
end

miligraf

Rails, or Active Record in this case, only identifies indexes with the following name pattern:

index_<table_name>_on_<column_name>

If name is different than that, it will completely ignore the index and won't use it.

search = params[:search][:text]
results = Object.any_of({ field1: /#{search}/ } , { field2: /#{search}/ })
