Some gems and plug-ins of Rails Applications

What is rubygems?

Rubygems (GEMS) is a ruby packaging system used to package rails components. It provides a standard format for distributing Ruby programs and libraries, and a tool for managing package installation.

Rubygems functions similar to Apt-get in Linux. It allows you to easily download and install rails from a remote server.

Open the command line window (CMD) and enter the execution command gem install rails -- remote or gem install rails -- include-dependencies.

1. gem on rails

  Link or freeze RubyGems into your rails apps, instead of just plugins. 

2.  request-log-analytizer

3.  mem-cached  :: cached_model  

Install: sudo gem install cached_model

Many speedy sites use memcached to save the results of expensive database queries and intense rendered templates. This is a basic introduction to using memcached with Rails. 

4. CSS graphs: report tool

A Ruby on Rails helper for making simple graphs. The graphs use onlyCSS/HTML (and an optional gradient image).

5. Bullet: optimizes data query performance

The Bullet plugin/gem is designed to help you increase your application’s performance by reducing the number of queries it makes. 

6.rails_reviewer        

The project encountered serious performance problems, mainly because there were too many database queries. We recommend the rails_reviewer plug-in.

7. Benchmark Test

14. logrotate automatically packs rails logs

15. ar_mailer is a good email sending plug-in. its working principle is to divide mail sending into two parts. First, save the mail to the database, and then call the background program to Implement Asynchronous sending, unfortunately, rails 3 is not supported yet, so it took an afternoon to port it to rails 3, which is: ar_mailer_rails3.

16.city_helper

17 .. rcov is a tool used to diagnose Ruby code coverage. Its main purpose is to determine whether unit tests cover all the code. When rcov uses an optimized C runtime, therefore, the performance is amazing, and it also provides output in multiple formats.
