如何 rake db:migrate 插件里面的migration

1.在 lib/task 中新建一个 install_system.rake

 

2. 复制这段代码

 

namespace :db do
 
  namespace :migrate do
    desc "Install system"
    task :install_system => :environment do
      raise "PLUGIN is require when specify PLUGIN_VERSION" if !ENV['PLUGIN']
      plugin_path = "#{RAILS_ROOT}/vendor/plugins/#{ENV['PLUGIN']}/db/migrate"
      raise "Unknown plugin: #{ENV["PLUGIN"]}"  if !File.exist?(plugin_path)
      ActiveRecord::Migration.verbose = ENV["VERBOSE"] ? ENV["VERBOSE"] == "true" : true
      puts plugin_path
      ActiveRecord::Migrator.migrate(plugin_path)
      Rake::Task["db:schema:dump"].invoke if ActiveRecord::Base.schema_format == :ruby
    end
   
  end
 
end

 

 

3.

 rake db:migrate:install_system PLUGIN=[插件名]
