使用本身包含多个块的块重构方法
我正在使用 Ruby 1.9.2
我有一个名为 search 的类方法,它需要一个块,
例如
class MyClass
def self.search do
if criteria1
keywords "abcde", fields: :c1 do
minimum_match(1)
end
end
if criteria2
keywords "defghi", fields: :c2 do
minimum_match(1)
end
end
end
end
我想做的是重构 MyClass.search 方法,并为每个 if/end 语句提供一个简单的一行方法,
例如它看起来像这样:
class MyClass
def self.search do
c1_method
c2_method
end
def self.c1_method
if criteria1
return keywords "abcde", fields: :c1 do
minimum_match(1)
end
end
end
def self.c2_method
if criteria2
return keywords "defghi", fields: :c2 do
minimum_match(1)
end
end
end
end
但是我上面展示的重构不太有效。看起来我在 c1_method 和 c2_method 中返回的“块”并没有真正在搜索方法中返回和评估,但我不知道该怎么做。
I'm using Ruby 1.9.2
I have a class method called search that takes a block
e.g.
class MyClass
def self.search do
if criteria1
keywords "abcde", fields: :c1 do
minimum_match(1)
end
end
if criteria2
keywords "defghi", fields: :c2 do
minimum_match(1)
end
end
end
end
What I'd like to do is refactor the MyClass.search method and have a simple one-line method for each if/end statement
e.g. it would look something like this:
class MyClass
def self.search do
c1_method
c2_method
end
def self.c1_method
if criteria1
return keywords "abcde", fields: :c1 do
minimum_match(1)
end
end
end
def self.c2_method
if criteria2
return keywords "defghi", fields: :c2 do
minimum_match(1)
end
end
end
end
But the refactoring that I show above doesn't quite work. It looks like the "blocks" that I'm returning in c1_method and c2_method aren't really being returned and evaluated in the search method, but I'm not sure how to do that.

那么,您可以使用
method(sym)
调用来获取方法的主体。Well, you can use the
method(sym)
call in order to get at the body of a method.
