我有一个数组:
@available_languages = ["English", "German", "Japanese"]
和变量:
@needed_language = "Basic English"
我想展示'可用!'在视图中,如果@available_languages数组中存在@needed_language,即使名称不完全匹配,例如“英语”和“基本英语”
现在,我的条件只对完全匹配返回true。如何针对非完全匹配返回true?
- if @available_languages.map{|a| a.available_language_name}.include? @needed_language.needed_language_name
Available!
- else
Not Available

您可以使用select函数,如下所示:
@available_languages = ["English", "German", "Japanese"]
@needed_language = "Basic English"
if @needed_language.split(" ").select{ |a| a if @available_languages.include? a} then
"Available"
else
"Not Available"
endif
