類型化JSON序列化/反序列化

Question

class Person: 
    first_name = superjson.Property() 
    last_name = superjson.Property() 
    posts = superjson.Collection(Post) 

class Post: 
    title = superjson.Property() 
    description = superjson.Property() 

# ^^^ this approach is very similar to Django models/forms 

然後：

{ 
    "first_name": "John", 
    "last_name": "Smith", 
    "posts": [ 
    {"title": "title #1", "description": "description #1"}, 
    {"title": "title #2", "description": "description #2"}, 
    {"title": "title #3", "description": "description #3"} 
    ] 
} 

我想它來建立的一切適當Person對象裏面設置：

p = superjson.deserialize(json, Person) # note, root type is explicitly provided 
print p.first_name # 'John' 
print p.last_name # 'Smith' 
print p.posts[0].title # 'title #1' 
# etc... 

• 當然它也應該有助於序列化
• 它應該序列化/默認情況下將時間從ISO-8601中反序列化，或者在幾行代碼中很容易實現。

所以，我正在尋找這superjson。有沒有人看到類似的東西？

Colander，加上limone完全是這樣。

您定義使用colander架構：

import colander 
import limone 


@limone.content_schema 
class Characteristic(colander.MappingSchema): 
    id = colander.SchemaNode(colander.Int(), 
          validator=colander.Range(0, 9999)) 
    name = colander.SchemaNode(colander.String()) 
    rating = colander.SchemaNode(colander.String())   


class Characteristics(colander.SequenceSchema): 
    characteristic = Characteristic() 


@limone.content_schema 
class Person(colander.MappingSchema): 
    id = colander.SchemaNode(colander.Int(), 
          validator=colander.Range(0, 9999)) 
    name = colander.SchemaNode(colander.String()) 
    phone = colander.SchemaNode(colander.String()) 
    characteristics = Characteristics() 


class Data(colander.SequenceSchema): 
    person = Person() 

然後傳遞到自己的JSON數據結構：

deserialized = Data().deserialize(json.loads(json_string))
