跳過初始化器，如果沒有rails s運行它

Question

我已經在初始化器中有一些代碼，我希望它只在服務器啓動時運行，而不是在控制檯啓動時運行。有什麼辦法讓他們分開？

謝謝！

Answer 1

我對這個任務

#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

你可以檢查Rails的控制檯定義：

run_code unless defined?(Rails::Console)

需要檢查服務器是否在運行，您可以使用這一個

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