Question

我很想知道,这部法典是否可以归入一条线:

if self.id
  return if Party.find_by_id(self.id).name.downcase == self.name.downcase
end

我很想知道,在一条行文中,有没有办法发表这一声明。

I know you can use if statement ? then_statement : else_statement but hopefully you can see here that there is no else. Perhaps break or continue or something like that? (Feel free to make optimisation to the actual code if you see it - that s pretty much the purpose here)

Answer 1

简明扼要,仅 j合:

return if self.id && Party.find_by_id(self.id).name.downcase == self.name.downcase

Answer 2

这些都是相当的:

if some_condition
    do_something
end

if some_condition; do_something; end

do_something if some_condition;

some_condition and do_something

但当然,你的例子已经使用了两种变式:
