Reformer

Simple and beautiful library for data formatting/convert/serialize

pip install reformer

Why

There are many great python libraries for validation, serialization and data formatting search as marshmallow, DRF etc. Usually they base on data validation.

Otherwise reformer design only for data formatting, and in a schema you need to define type of transformation and data source.

How to use

To define schema you need to create Reformer base class:

from reformer import Reformer, Field, MapField, MethodField

class Schema(Reformer):
    _fields_ = ('name', 'surname')
    fullname = Field('name').replace('_', '-')  + ' ' + Field('surname')
    admin = Field('username').at(['admin', 'root'])
    welcome = MapField('username', {
        'admin': 'Hi bro',
        'root':  'God?'
    })
    posts_titles = Field('posts').iter(['title'])
    status = ('http://api.com/get_user_status/' + Field('id', to=str)).handle(requests.get)


target = {
    'id': 353,
    'name': 'John',
    'surname': 'Black',
    'username': 'admin',
    'posts': [
        {'title': 'New', 'id': 10},
        {'title': 'My first post', 'id': 11},
    ]
}

print(Schema.transform(target))
# OrderedDict([
#    ('name', 'John'),
#    ('surname', 'Black'),
#    ('fullname', 'John Black'),
#    ('admin', True),
#    ('welcome', 'Hi bro'),
#    ('posts_titles', ['New', 'My first post']),
#    ('status', 'INIT'),
# ])
