安装

pip install schemv

描述

schematics 不支持数据类型强校验,在原有包基础上修改加入数据类型强校验, 性能远超cerberus校验框架

例子

This is a simple Model.

>>> from schemv.models import Model
  >>> from schemv.types import StringType, URLType
  >>> class Person(Model):
  ...     name = StringType(required=True)
  ...     website = URLType()
  ...
  >>> person = Person({'name': u'Joe Strummer',
  ...                  'website': 'http://soundcloud.com/joestrummer'})
  >>> person.name
  u'Joe Strummer'

Serializing the data to JSON.
>>> from schemv.types import StringType, URLType
>>> class Person(Model):
...     name = StringType(required=True)
...     website = URLType()
...
>>> person = Person({'name': u'Joe Strummer',
...                  'website': 'http://soundcloud.com/joestrummer'})
>>> person.name
u'Joe Strummer'

Serializing the data to JSON.

>>> import json
>>> json.dumps(person.to_primitive())
{"name": "Joe Strummer", "website": "http://soundcloud.com/joestrummer"}

Let's try validating without a name value, since it's required.

>>> person = Person()
>>> person.website = 'http://www.amontobin.com/'
>>> person.validate()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "schematics/models.py", line 231, in validate
    raise DataError(e.messages)
schemv.exceptions.DataError: {'name': ['This field is required.']}

Add the field and validation passes.

>>> person = Person()
>>> person.name = 'Amon Tobin'
>>> person.website = 'http://www.amontobin.com/'
>>> person.validate()
>>>
