Spree-基于Ruby on Rails的一个开源的电子商务网站源码

Spree is a complete open source e-commerce solution built with Ruby on Rails. It was originally developed by Sean Schofield and is now maintained by a dedicated core team. You can find out more by visiting the Spree e-commerce project page.
Spree actually consists of several different gems, each of which are maintained in a single repository and documented in a single set of online documentation. By requiring the Spree gem you automatically require all of the necessary gem dependencies which are:

• spree_api (RESTful API)
• spree_frontend (User-facing components)
• spree_backend (Admin area)
• spree_cmd (Command-line tools)
• spree_core (Models & Mailers, the basic components of Spree that it can't run without)
• spree_sample (Sample data)

All of the gems are designed to work together to provide a fully functional e-commerce platform. It is also possible, however, to use only the pieces you are interested in. For example, you could use just the barebones spree_core gem and perhaps combine it with your own custom backend admin instead of using spree_api.

Installation

THIS README IS FOR THE MASTER BRANCH OF SPREE AND REFLECTS THE WORK CURRENTLY EXISTING ON THE MASTER BRANCH. IF YOU ARE WISHING TO USE A NON-MASTER BRANCH OF SPREE, PLEASE CONSULT THAT BRANCH'S README AND NOT THIS ONE.
The fastest way to get started is by using the spree command line tool available in the spree gem which will add Spree to an existing Rails application.

gem install rails -v 4.0.0
gem install spree
rails _4.0.0_ new my_store
spree install my_store

This will add the Spree gem to your Gemfile, create initializers, copy migrations and optionally generate sample products and orders.
If you get an "Unable to resolve dependencies" error when installing the Spree gem then you can try installing just the spree_cmd gem which should avoid any circular dependency issues.

gem install spree_cmd

To auto accept all prompts while running the install generator, pass -A as an option

spree install my_store -A

Using stable builds and bleeding edge

To use a stable build of Spree, you can manually add Spree to your Rails 4.0.x application. To use the 2-1-stable branch of Spree, add this line to your Gemfile.

gem 'spree', github: 'spree/spree', branch: '2-1-stable'

Alternatively, if you want to use the bleeding edge version of Spree, use this line:

gem 'spree', github: 'spree/spree'

Note: The master branch is not guaranteed to ever be in a fully functioning state. It is unwise to use this branch in a production system you care deeply about.
If you wish to have authentication included also, you will need to add the spree_auth_devise gem as well. Either this:

gem 'spree_auth_devise', github: 'spree/spree_auth_devise', branch: '2-1-stable'

Or this:

gem 'spree_auth_devise', github: 'spree/spree_auth_devise'

Once you've done that, then you can install these gems using this command:

bundle install

Use the install generator to set up Spree:

rails g spree:install --sample=false --seed=false

At this point, if you are using spree_auth_devise you will need to change this line in config/initializers/spree.rb:

Spree.user_class = "Spree::LegacyUser"

To this:

Spree.user_class = "Spree::User"

You can avoid running migrations or generating seed and sample data by passing in these flags:

rails g spree:install --migrate=false --sample=false --seed=false

You can always perform the steps later by using these commands.

bundle exec rake railties:install:migrations
bundle exec rake db:migrate
bundle exec rake db:seed
bundle exec rake spree_sample:load

Working with the edge source (latest and greatest features)

The source code is essentially a collection of gems. Spree is meant to be run within the context of Rails application. You can easily create a sandbox application inside of your cloned source directory for testing purposes.

1. Clone the Git repo

git clone git://github.com/spree/spree.git
cd spree

1. Install the gem dependencies

bundle install

1. Create a sandbox Rails application for testing purposes (and automatically perform all necessary database setup)

bundle exec rake sandbox

1. Start the server

cd sandbox
rails server

Performance

You may notice that your Spree store runs slowly in development mode. This is a side-effect of how Rails works in development mode which is to continuously reload your Ruby objects on each request. The introduction of the asset pipeline in Rails 3.1 made default performance in development mode significantly worse. There are, however, a few tricks to speeding up performance in development mode.
You can precompile your assets as follows:

bundle exec rake assets:precompile:nondigest

If you want to remove precompiled assets (recommended before you commit to Git and push your changes) use the following rake task:

bundle exec rake assets:clean

Use Dedicated Spree Devise Authentication

Add the following to your Gemfile

gem 'spree_auth_devise', github: 'spree/spree_auth_devise'

Then run bundle install. Authentication will then work exactly as it did in previous versions of Spree.
This line is automatically added by the spree install command.
If you're installing this in a new Spree 1.2+ application, you'll need to install and run the migrations with

bundle exec rake spree_auth:install:migrations
bundle exec rake db:migrate

change the following line in config/initializers/spree.rb

Spree.user_class = 'Spree::LegacyUser'

to

Spree.user_class = 'Spree::User'

In order to set up the admin user for the application you should then run:

bundle exec rake spree_auth:admin:create

Running Tests

We use TeamCity to run the tests for Spree.
You can see the build statuses at http://ci.spree.fm.

---

Each gem contains its own series of tests, and for each directory, you need to do a quick one-time creation of a test application and then you can use it to run the tests. For example, to run the tests for the core project.

cd core
bundle exec rake test_app
bundle exec rspec spec

If you would like to run specs against a particular database you may specify the dummy apps database, which defaults to sqlite3.

DB=postgres bundle exec rake test_app

If you want to run specs for only a single spec file

bundle exec rspec spec/models/state_spec.rb

If you want to run a particular line of spec

bundle exec rspec spec/models/state_spec.rb:7

You can also enable fail fast in order to stop tests at the first failure

FAIL_FAST=true bundle exec rspec spec/models/state_spec.rb

If you want to run the simplecov code coverage report

COVERAGE=true bundle exec rspec spec

If you're working on multiple facets of Spree, you may want to run this command at the root of the Spree project to generate test applications and run specs for all the facets:

bash build.sh
