Capistrano的任務

Question

我的問題是類似How do I invoke one Capistrano task from another?

我想是能夠額外的東西來傳遞參數從富時調用它吧：

task :foo do 
    # this calls bar, I would like to pass params (i.e n = 10) 
    # as if I were calling cap bar -s n=10 
    # bar does not take arguments 
    bar 
end 

task :bar do 
    if exists?(:n) 
    puts "n is: #{n}" 
    end 
end 

Answer 1

Capistrano的任務都可以」真的被參數化。您可以定義一個輔助方法，具體如下：

task :foo do 
    bar(10) 
end 

def bar(n=variables[:n]) 
    puts "N is #{n}" 
end 

如果您在具有很死心塌地：酒吧是一項任務爲好，試試這招：

task :foo do 
    bar(10) 
end 

task :bar { bar } 

def bar(n=variables[:n]) 
    puts "N is #{n}" 
end 

注意任務必須是在方法之前聲明。

在Capistrano的3.X

desc "I accept a parameter" 
task :foo, :foo_param do |t, args| 
    foo_param = args[:foo_param] 
    puts "I am #{foo_param}" 
end 

desc "I call the foo task" 
task :bar do 
    invoke("foo", "batman") 
    # prints "I am batman" 
end
