Rails 3：JSON 字符串中出现转义字符 (\)
有人知道为什么我的一些 json 元素被反斜杠(\) 转义，而其他元素却没有？
{"first":"John","last":"Smith","dogs":"[{\"name\":\"Rex\",\"breed\":\"Lab\"},{\"name\":\"Spot\",\"breed\":\"Dalmation\"},{\"name\":\"Fido\",\"breed\":\"Terrier\"}]"}
理想情况下，我不希望它们中的任何一个被转义...
这是通过在两个模型中重写 as_json 生成的。人有很多狗。
#models/person.rb
class Person < ActiveRecord::Base
has_many :dogs
def as_json(options={})
{
:first => first,
:last => last,
:dogs => dogs.to_json
}
end
end
#models/dog.rb
class Dog < ActiveRecord::Base
belongs_to :people
def as_json(options={})
{
:name => name,
:breed => breed
}
end
end
Anyone know why some of my json elements are being backslash(\) escaped while others are not?
{"first":"John","last":"Smith","dogs":"[{\"name\":\"Rex\",\"breed\":\"Lab\"},{\"name\":\"Spot\",\"breed\":\"Dalmation\"},{\"name\":\"Fido\",\"breed\":\"Terrier\"}]"}
Ideally I'd like NONE of them to be escaped...
This was generated by overriding as_json in two models. Person has_many Dogs.
#models/person.rb
class Person < ActiveRecord::Base
has_many :dogs
def as_json(options={})
{
:first => first,
:last => last,
:dogs => dogs.to_json
}
end
end
#models/dog.rb
class Dog < ActiveRecord::Base
belongs_to :people
def as_json(options={})
{
:name => name,
:breed => breed
}
end
end

查看 jonathanjulian.com 的 Rails to_json 或 as_json？

尝试删除
dogs.to_json上的to_json。Try removing the
to_jsonondogs.to_json.
