跳过初始化器，如果没有rails s运行它

Question

我已经在初始化器中有一些代码，我希望它只在服务器启动时运行，而不是在控制台启动时运行。有什么办法让他们分开？

谢谢！

Answer 1

我对这个任务

#lib/initializer_helpers.rb 
module InitializerHelpers 

    def self.skip_console_rake_generators &block 
    skip(defined?(Rails::Console) || defined?(Rails::Generators) || File.basename($0) == "rake", &block) 
    end 

    def self.skip_rake_generators &block 
    skip(defined?(Rails::Generators) || File.basename($0) == "rake", &block) 
    end 

    def self.skip_generators &block 
    skip(defined?(Rails::Generators), &block) 
    end 

    def self.skip_console &block 
    skip(defined?(Rails::Console), &block) 
    end 

    private 

    def self.skip(condition, &block) 
    raise ArgumentError.new("no block given") if block.blank? 
    unless condition 
     yield 
    end 
    end 

end 

# use it 
InitializerHelpers.skip_console do 
    # not executed in console 
end

你可以检查Rails的控制台定义：

run_code unless defined?(Rails::Console)

需要检查服务器是否在运行，您可以使用这一个

if defined?(Rails::Server) 
    # do something usefull 
end
