在 ruby 中,如何将函数的 response/results 转换为数组?
In ruby, how can I convert a function's response/results into an array?
在ruby中,如何将函数响应转换为数组供以后使用?
array = []
def function (subject1)
results = client.get('/subjects', :genre => subject1)
results.each { |r| puts r.title }
array << r.title
end
function(subject1)
我的代码与上面类似。然而,我的结果永远不会被存储。请并感谢您的帮助:)
每个方法都会遍历每个元素,而 map 本身会 return 一个数组。
def function(subject1)
results = client.get('/subjects', :genre => subject1)
results.map { |r| r.title }
end
function(subject1)
"My results however are never stored" - 然后存储结果:
result = function(subject1)
或者你可以让数组成为一个全局变量
$array = []
def function (subject1)
results = client.get('/subjects', :genre => subject1)
results.each { |r| $array << r.title }
end
function(subject1)
或者您可以这样做
array = []
def function (subject1)
results = client.get('/subjects', :genre => subject1)
results.each { |r| puts r.title }
end
array = function(subject1)
