六.slim-template/slim-rails

 

slim-rails provides Slim generators for Rails 3 and 4. It was based on haml-rails and it does basically the same:

  • Any time you generate a controller or scaffold, you'll get Slim templates (instead of ERB)
  • When your Rails application loads, Slim will be loaded and initialized automatically
  • Slim templates will be respected by the view template cache digestor

slim_rails提供了为Rails3和Rails4的Slim语言生成器,它基于haml-rails,而且他们特点基本上是相同的,如下:

   1.无论何时何地你用rails生成了一个控制器或者脚手架,你都会得到Slim语言的模板(替代ERB,因此ERB文件就消失了)。

   2.当你加载Rails应用时,Slim将会自动初始化和加载。

   3.当访问缓存器的时候,Slim模板将会被慎重对待。

  • immigrant - Adds a generator for creating a foreign key migration based on your current model associations

Rack::Accept is a suite of tools for Ruby/Rack applications that eases the complexity of building and interpreting the Accept* family of HTTP request headers.

Active Record Named Scopes

  • filterrific - Filterrific is a Rails Engine plugin that makes it easy to filter, search, and sort your ActiveRecord lists.

Some features of the library are:

Active Record Nesting

  • Awesome nested set - An awesome nested set implementation for Active Record
  • Ancestry - Ancestry allows the records of a ActiveRecord model to be organized in a tree structure, using a single, intuitively formatted database column. It exposes all the standard tree structure relations (ancestors, parent, root, children, siblings, descendants) and all of them can be fetched in a single sql query. Additional features are named_scopes, integrity checking, integrity restoration, arrangement of (sub)tree into hashes and different strategies for dealing with orphaned records.

Active Record Soft Delete

  • paranoia - Paranoia is a re-implementation of acts_as_paranoid for Rails 3, using much, much, much less code. You would use either plugin / gem if you wished that when you called destroy on an Active Record object that it didn't actually destroy it, but just "hid" the record. Paranoia does this by setting a deleted_at field to the current time when you destroy a record, and hides it by scoping all queries on your model to only include records which do not have a deleted_at field.
  • Permanent records - Never Lose Data. Rather than deleting rows this sets Record#deleted_at and gives you all the scopes you need to work with your data.
  • destroyed_at - Safe destroy for ActiveRecord.

1.严格遵守RFC 2616,具体请看section 14

Active Record Sortables

  • Acts as list - This "acts_as" extension provides the capabilities for sorting and reordering a number of objects in a list. The class that has this specified needs to have a "position" column defined as an integer on the mapped database table.

   2.全面支持1中的Accept, Accept-Charset, Accept-Encoding,Accept-Language HTTP请求头。

Active Record User Stamping

必赢手机登录网址 ,   3.可以独立使用或者用做RACK中间件

Active Record Value Cleanup

  • Strip attributes - StripAttributes automatically strips all ActiveRecord model attributes of leading and trailing whitespace before validation. If the attribute is blank, it strips the value to nil.

   4.拥有一个很全面的测试套间,涵盖了许多边缘情况

Active Record Versioning

  • PaperTrail - Track changes to your models' data. Good for auditing or versioning.
  • audited - Log all changes to your models
  • auditable - A simple gem that audit ActiveRecord models' attributes or methods by taking snapshots and diff them for you. Starting from scratch to work with Rails 3.2.2 onwards

Rails Ratings

三.slim-template/html2slim

Rails Search

  • Sunspot - Sunspot is a library providing a powerful, all-ruby API for the Solr search engine. Sunspot manages the configuration of persistent Ruby classes for search and indexing and exposes Solr's most powerful features through a collection of DSLs. Complex search operations can be performed without hand-writing any boolean queries or building Solr parameters by hand.
  • sunspot_rails - Sunspot::Rails is an extension to the Sunspot library for Solr search. Sunspot::Rails adds integration between Sunspot and ActiveRecord, including defining search and indexing related methods on ActiveRecord models themselves, running a Sunspot-compatible Solr instance for development and test environments, and automatically commit Solr index changes at the end of each Rails request.
  • Thinking-sphinx - An intelligent layer for ActiveRecord (via Rails and Sinatra) for the Sphinx full-text search tool.
  • Tire - Tire is a Ruby client for the Elasticsearch search engine/database. It provides Ruby-like API for fluent communication with the Elasticsearch server and blends with ActiveModel class for convenient usage in Rails applications. It allows to delete and create indices, define mapping for them, supports the bulk API, and presents an easy-to-use DSL for constructing your queries. It has full ActiveRecord/ActiveModel compatibility, allowing you to index your models (incrementally upon saving, or in bulk), searching and paginating the results. Please check the documentation at http://karmi.github.com/retire/.
  • searchkick - Intelligent search made easy
  • elasticsearch - Ruby integrations for Elasticsearch (client, API, etc.)
  • pg_search - PgSearch builds Active Record named scopes that take advantage of PostgreSQL's full text search
  • elasticsearch-rails - Ruby on Rails integrations for Elasticsearch.
  • Scoped search - Scoped search makes it easy to search your ActiveRecord-based models. It will create a named scope :search_for that can be called with a query string. It will build an SQL query using the provided query string and a definition that specifies on what fields to search. Because the functionality is built on named_scope, the result of the search_for call can be used like any other named_scope, so it can be chained with another scope or combined with will_paginate. Because it uses standard SQL, it does not require any setup, indexers or daemons. This makes scoped_search suitable to quickly add basic search functionality to your application with little hassle. On the other hand, it may not be the best choice if it is going to be used on very large datasets or by a large user base.
  • searchlight - Searchlight is a low-magic way to build database searches using an ORM. It's compatible with ActiveRecord, Sequel, Mongoid, and any other ORM that can build queries by chaining method calls.
  • elastictastic - Elastictastic is an object-document mapper and lightweight API adapter for ElasticSearch. Elastictastic's primary use case is to define model classes which use ElasticSearch as a primary document-oriented data store, and to expose ElasticSearch's search functionality to query for those models.

Script for converting HTML and ERB files to slim (slim-lang.org).

Rails Tagging

  • Acts-as-taggable-on - With ActsAsTaggableOn, you can tag a single model on several contexts, such as skills, interests, and awards. It also provides other advanced functionality.

It's not perfect, but certainly it helps a lot!

Background Processing

It's based on Hpricot. Yeah, I'm old school.

Background Jobs

  • Resque - Resque is a Redis-backed Ruby library for creating background jobs, placing those jobs on multiple queues, and processing them later. Background jobs can be any Ruby class or module that responds to perform. Your existing classes can easily be converted to background jobs or you can create new classes specifically to do work. Or, you can do both. Resque is heavily inspired by DelayedJob (which rocks) and is comprised of three parts: * A Ruby library for creating, querying, and processing jobs * A Rake task for starting a worker which processes jobs * A Sinatra app for monitoring queues, jobs, and workers.
  • sidekiq - Simple, efficient background processing for Ruby.
  • Delayed job - Delayed_job (or DJ) encapsulates the common pattern of asynchronously executing longer tasks in the background. It is a direct extraction from Shopify where the job table is responsible for a multitude of core tasks.
  • Beanstalkd - Beanstalk is a simple, fast work queue.
  • Bunny - Easy to use, feature complete Ruby client for RabbitMQ 3.3 and later versions.
  • concurrent-ruby - Modern concurrency tools including agents, futures, promises, thread pools, actors, supervisors, and more. Inspired by Erlang, Clojure, Go, JavaScript, actors, and classic concurrency patterns.
  • delayed_job_active_record - ActiveRecord backend for Delayed::Job, originally authored by Tobias Lütke
  • sucker_punch - Asynchronous processing library for Ruby
  • amqp - Mature EventMachine-based RabbitMQ client.
  • Queue Classic - queue_classic is a queueing library for Ruby apps. (Rails, Sinatra, Etc...) queue_classic features asynchronous job polling, database maintained locks and no ridiculous dependencies. As a matter of fact, queue_classic only requires pg.
  • Cloud-crowd - The crowd, suddenly there where there was nothing before, is a mysterious and universal phenomenon. A few people may have been standing together -- five, ten or twelve, nor more; nothing has been announced, nothing is expected. Suddenly everywhere is black with people and more come streaming from all sides as though streets had only one direction.
  • backburner - Beanstalk background job processing made easy
  • Beetle - A highly available, reliable messaging infrastructure

Net::LDAP has been tested against modern popular LDAP servers including OpenLDAP and Active Directory. The current release is mostly compliant with earlier versions of the IETF LDAP RFCs (2251-2256, 2829-2830, 3377, and 3771). Our roadmap for Net::LDAP 1.0 is to gain full <em>client</em> compliance with the most recent LDAP RFCs (4510-4519, plutions of 4520-4532).

"I had a class with Jim Weirich on testing last week and we were allowed to choose our testing frameworks. Kirk Haines and I were paired up and we cracked open the code for a few test frameworks... I MUST say that minitest is very readable / understandable compared to the 'other two' options we looked at. Nicely done and thank you for helping us keep our mental sanity." -- Wayne E. Seguin minitest/test is a small and incredibly fast unit testing framework. It provides a rich set of assertions to make your tests clean and readable. minitest/spec is a functionally complete spec engine. It hooks onto minitest/test and seamlessly bridges test assertions over to spec expectations. minitest/benchmark is an awesome way to assert the performance of your algorithms in a repeatable manner. Now you can assert that your newb co-worker doesn't replace your linear algorithm with an exponential one! minitest/mock by Steven Baker, is a beautifully tiny mock (and stub) object framework. minitest/pride shows pride in testing and adds coloring to your test output. I guess it is an example of how to write IO pipes too. :P minitest/test is meant to have a clean implementation for language implementors that need a minimal set of methods to bootstrap a working test suite. For example, there is no magic involved for test-case discovery. "Again, I can't praise enough the idea of a testing/specing framework that I can actually read in full in one sitting!" -- Piotr Szotkowski Comparing to rspec: rspec is a testing DSL. minitest is ruby. -- Adam Hawkins, "Bow Before MiniTest" minitest doesn't reinvent anything that ruby already provides, like: classes, modules, inheritance, methods. This means you only have to learn ruby to use minitest and all of your regular OO practices like extract-method refactorings still apply.
