This is library is to help facilitate creating objects from common text based representation formates(json, yaml, and python dics). The following response will be used for a common example.

{
   "id":1,
   "name":"Gold Start Ablum",
   "postal_code":44024,
   "created_at":"2015-04-24T21:51:50.691473",
   "songs":[
      {
         "id":1,
         "name":"songname"
      }
   ],
   "author":{
      "id":1,
      "name":"test author",
      "info":{
         "id":1,
         "email":"test@example.com"
      }
   },
   "_links":{
      "self":"testselflink",
      "next":"testnextlink",
      "embedded":{
         "embedded_link":"testembeddedlink"
      }
   },
   "list_thing":[
      1,
      2,
      3,
      4
  ]
}

Supported Formats

• from_json
• from_yaml

• from_dict

• to_json

• to_yaml
• to_dicttw

Renaming Attributes

class Record(typify.Model):
    zip = typify.IntegerMatcher(key='postal_code')

Parsing Attributes into complex type

class Record(typify.Model):
    created_at = typify.StringMatcher(parse=lambda x: datetime.datetime.strptime(x, '%Y-%m-%dT%H:%M:%S.%f'))

Converting complex type when writing to json

class Record(typify.Model):
    created_at = typify.StringMatcher(convert=lambda x: x.isoformat(), default=lambda: datetime.datetime.now())

Wrapped attributes

class Record(typify.Model):
    self = typify.StringMatcher(wrap='_links')
    embedded_link = typify.StringMatcher(wrap=['_links', 'embedded'])

Nested Objects

class Author(typify.Model):                                                                                                                                                                    
    id = typify.IntegerMatcher()                                                                                                                                                               
    name = typify.StringMatcher()

class Record(typify.Model): 
    author = typify.ObjectMatcher(Author)

Objects can be nested forever and ever

 class AuthorInfo(typify.Model):                                                                                                                                                                
    id = typify.IntegerMatcher()                                                                                                                                                               
    email = typify.StringMatcher()  

class Author(typify.Model):                                                                                                                                                                    
    id = typify.IntegerMatcher()                                                                                                                                                               
    name = typify.StringMatcher()
    info  = typify.ObjectMatcher(AuthorInfo)

class Record(typify.Model): 
    author = typify.ObjectMatcher(Author)

Collections of objects

class Song(typify.Model):
