Tuning

Common tools used in rails extracted into a gem.

Why

I did this gem to:

• Make features I commonly need work nice together.
• Have an extensible container to continue adding new general purpose tools.

Install

Put this line in your Gemfile:

gem 'tuning'

Then bundle:

$ bundle

Usage

Controllers

New callbacks before, after, around render are available:

class ProductsController < ApplicationController

  before_action :set_product
  before_render :prepare_product

  def edit
  end

  private

  def set_product
    @product = Product.find(params[:id])
  end

  def prepare_product
    @product.build_picture
  end

end

Mailers

Text email templates will normalize spaces and new lines like html:

<% if @order.confirmed? %>
  Your order has been confirmed.

  Will be delivered right the way.
<% end %>

Will produce:

Your order has been confirmed.

Will be delivered right the way.

Views

New content_tag_if method to wrap content into some tag if certain condition it's true:

<%= content_tag_if request.path == home_path, :h1 do %>
  <%= link_to 'Home', home_path, id: 'logo' %>
<% end %>

New active_trail? method to check if some path is on active trail:

<li class="<%= 'active' if active_trail? some_path %>"></li>

New extending method to extend layouts:

<%= extending :application do %>
  <p>content</p>
<% end %>

Template Handlers

Ruby template handlers will automatically call to_json or to_xml:

@users.map do |user|
  user.slice :name
end

Records

Empty strings will be nilify in the database to avoid sql errors or complex queries:

shop = Shop.new(name: '')
shop.save
shop.name # Will be nil

New method validate is available to allow a more expressive syntax:

record.validate

Validations

New complexity validator to avoid weak passwords:

class User < ActiveRecord::Base
  validates_complexity_of :password
end

New time validator to validate Date/Time using after, after_or_equal_to, before or before_or_equal_to:

class Schedule < ActiveRecord::Base
  validates_time_of :opens_at
  validates_time_of :closes_at, after: :opens_at
end

New count validator to express count messages using minimum, maximum, in o within:

class Product < ActiveRecord::Base
  validates_count_of :pictures, minimum: 1, maximum: 4
end

NOTE: Take a look at lib/tuning/locales to know the i18n keys.

Contributing

Any issue, pull request, comment of any kind is more than welcome!

I will mainly ensure compatibility to PostgreSQL, AWS, Redis, Elasticsearch, FreeBSD and Memcached.
