if subject.downcase.include? product.name.downcase || body.downcase.include? product.name.downcase
puts "111"
end
为什么上面的红宝石有问题?有没有更好的方法来写这个?
这是结果错误:
SyntaxError: (irb):7: syntax error, unexpected tIDENTIFIER, expecting keyword_then or ';' or '\n'
... body.downcase.include? product.name.downcase
... ^
(irb):9: syntax error, unexpected keyword_end, expecting end-of-input
答案 0 :(得分:2)
这转换为:
if subject.downcase.include? (product.name.downcase || body.downcase.include? product.name.downcase)
您需要添加括号:
if subject.downcase.include?(product.name.downcase) || body.downcase.include? product.name.downcase
然而,这可能更具可读性:
if [subject, body].any? {|element| element.downcase.include? product.name.downcase}
