英文:
store the value in array and return the function ruby
问题
I understand your request. Here's the translated code and the modified function:
# 项目包含哈希数组，示例：
item = [{item1},{item2},{item3}]
def function1
item.map( other_class.call ).flatten
end
# 其他类将返回包含字符串的数组
class other_class
def call
# 返回字符串数组的方法
end
end
# 目前，function1 返回一个包含字符串值的数组的数组。
# 期望输出 = ["str1", "str2", "str3", "str4", "str5"]
# 有没有办法修改上述方法？
The modification to the function1 method involves adding the .flatten method to the result of item.map(other_class.call) to convert the array of arrays into a flat array of strings. This will give you the expected output.
英文:
item has array of hash. ex.
item = [{item1},{item2},{item3}]
def function1
item.map( other_class.call )
end
# other class will return the array which contains string
class other_class
def call
#method which return arrray of strings
end
end
currently the function1 is returning the array of array which has string values.
function1 output example [["str1"], [], ["str2"], ["str3"], ["str4","str5"]]
I want to modify the function1 which will return the array of string.
expected output = ["str1" "str2", "str3", "str4", "str5"]
Guys, any idea how can I modify the above method.
Thanks in advance.

得分: 1
Output
["str1", "str2", "str3", "str4", "str5"]
So you should write something like
def function1
other_class.call.flatten
end
英文:
Input
item=[["str1"], [], ["str2"], ["str3"], ["str4","str5"]]
Code
p item.flatten
output
["str1", "str2", "str3", "str4", "str5"]
So you should write something like
def function1
other_class.call.flatten
end
