mimesis 0.0.4

Documentation

Complete documentation for Mimesis is available here: http://mimesis.readthedocs.io/

Installation

To install Mimesis, simply:

➜  ~ pip install mimesis

Basic Usage:

>>> from mimesis import Personal, Address
>>> person = Personal('en')
>>> address = Address('en')

>>> person.full_name(gender='female')
'Antonetta Garrison'

>>> person.email(gender='male')
'oren5936@live.com'

>>> person.occupation()
'Programmer'

>>> address.address()
'713 Rock Stravenue'

>>> address.city()
'Dumont'

>>> address.country()
'Switzerland'

>>> address.country_iso(fmt='iso2')
'WF'

>>> address.country_iso(fmt='iso3')
'BFA'

>>> address.country_iso(fmt='numeric')
'744'

>>> address.continent()
'South America'

Locales

You can specify a locale when creating providers and they will return data that is appropriate for the language or country associated with that locale. Mimesis currently includes support for 32 different locales.

Using locales:

>>> from mimesis import Personal

>>> en = Personal('en')
>>> de = Personal('de')
>>> ic = Personal('is')

>>> en.full_name()
'Carolin Brady'

>>> de.full_name()
'Sabrina Gutermuth'

>>> ic.full_name()
'Rósa Þórlindsdóttir'

When you only need to generate data for a single locale, use the Generic provider, and you can access all Mimesis providers from one object.

>>> from mimesis import Generic
>>> g = Generic('es')

>>> g.datetime.month()
'Agosto'

>>> g.code.imei()
'353918052107063'

>>> g.food.fruit()
'Limón'




>>> from mimesis import Generic
>>> g = Generic('es')

>>> g.datetime.month()
'Agosto'

>>> g.code.imei()
'353918052107063'

>>> g.food.fruit()
'Limón'




>>> from mimesis import Generic
>>> g = Generic('es')

>>> g.datetime.month()
'Agosto'

>>> g.code.imei()
'353918052107063'

>>> g.food.fruit()
'Limón'

Advantages

Mimesis offers a number of advantages over other similar libraries, such as Faker:

• Performance. Mimesis is significantly faster than other similar libraries.

• Completeness. Mimesis strives to provide many detailed providers that offer a variety of data generators.

• Simplicity. Mimesis does not require any modules other than the Python standard library.

See here for an example of how we compare performance with other libraries.

Integration with Web Application Frameworks

You can use Mimesis during development and testing of applications built on a variety of frameworks. Here is an example of integration with a Flask application:

class Patient(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    full_name = db.Column(db.String(100))
    weight = db.Column(db.String(64))
    height = db.Column(db.String(64))
    blood_type = db.Column(db.String(64))
    age = db.Column(db.Integer)

    def __init__(self, **kwargs):
        super(Patient, self).__init__(**kwargs)

    @staticmethod
    def _bootstrap(count=500, locale='en', gender):
        from mimesis import Personal

        person = Personal(locale)

        for _ in range(count):
            patient = Patient(
                full_name=person.full_name(gender=gender),
                age=person.age(minimum=18, maximum=45),
                weight=person.weight(),
                height=person.height(),
                blood_type=person.blood_type(),
            )

            db.session.add(patient)
            try:
                db.session.commit()
            except IntegrityError:
                db.session.rollback()

Just run shell mode

(env) ➜ python3 manage.py shell

and do following:

>>> db
<SQLAlchemy engine='sqlite:///db_dev.sqlite'>

>>> Patient
<class 'app.models.Patient'>

>>> Patient()._bootstrap(count=1000, locale='en', gender='female')

Custom Providers

You also can add custom provider to Generic.

>>> class SomeProvider():
...
...     class Meta:
...         name = "some_provider"
...
...     @staticmethod
...     def one():
...         return 1

>>> class Another():
...
...     @staticmethod
...     def bye():
...         return "Bye!"

>>> generic.add_provider(SomeProvider)
>>> generic.add_provider(Another)

>>> generic.some_provider.one()
1

>>> generic.another.bye()
'Bye!'

Builtins specific data providers

Some countries have data types specific to that country. For example social security numbers in the United States (en locale), and cadastro de pessoas físicas (CPF) in Brazil (pt-br locale).

If you would like to use these country-specific providers, then you must import them explicitly:

>>> from mimesis import Generic
>>> from mimesis.builtins.pt_br import BrazilSpecProvider

>>> generic = Generic('pt-br')

>>> class BrazilProvider(BrazilSpecProvider):
...
...     class Meta:
...         name = "brazil_provider"
...
>>> generic.add_provider(BrazilProvider)
>>> generic.brazil_provider.cpf()
'696.441.186-00'




>>> from mimesis import Generic
>>> from mimesis.builtins.pt_br import BrazilSpecProvider

>>> generic = Generic('pt-br')

>>> class BrazilProvider(BrazilSpecProvider):
...
...     class Meta:
...         name = "brazil_provider"
...
>>> generic.add_provider(BrazilProvider)
>>> generic.brazil_provider.cpf()
'696.441.186-00'




>>> from mimesis import Generic
>>> from mimesis.builtins.pt_br import BrazilSpecProvider

>>> generic = Generic('pt-br')

>>> class BrazilProvider(BrazilSpecProvider):
...
...     class Meta:
...         name = "brazil_provider"
...
>>> generic.add_provider(BrazilProvider)
>>> generic.brazil_provider.cpf()
'696.441.186-00'




>>> from mimesis import Generic
>>> from mimesis.builtins.pt_br import BrazilSpecProvider

>>> generic = Generic('pt-br')

>>> class BrazilProvider(BrazilSpecProvider):
...
...     class Meta:
...         name = "brazil_provider"
...
>>> generic.add_provider(BrazilProvider)
>>> generic.brazil_provider.cpf()
'696.441.186-00'




>>> from mimesis import Generic
>>> from mimesis.builtins.pt_br import BrazilSpecProvider

>>> generic = Generic('pt-br')

>>> class BrazilProvider(BrazilSpecProvider):
...
...     class Meta:
...         name = "brazil_provider"
...
>>> generic.add_provider(BrazilProvider)
>>> generic.brazil_provider.cpf()
'696.441.186-00'

Decorators

If your locale is cyrillic, but you need latinized locale-specific data, then you can use special decorator. At this moment it’s work only for Russian:

>>> from mimesis import Personal
>>> from mimesis.decorators import romanized

>>> pr = Personal('ru')

>>> @romanized('ru')
... def get_name_ro():
...     return pr.full_name()
...

>>> def get_name_ru():
...     return pr.full_name()
...

>>> get_name_ru()
'Вида Панова'

>>> get_name_ro()
'Veronika Denisova'




>>> from mimesis import Personal
>>> from mimesis.decorators import romanized

>>> pr = Personal('ru')

>>> @romanized('ru')
... def get_name_ro():
...     return pr.full_name()
...

>>> def get_name_ru():
...     return pr.full_name()
...

>>> get_name_ru()
'Вида Панова'

>>> get_name_ro()
'Veronika Denisova'




>>> from mimesis import Personal
>>> from mimesis.decorators import romanized

>>> pr = Personal('ru')

>>> @romanized('ru')
... def get_name_ro():
...     return pr.full_name()
...

>>> def get_name_ru():
...     return pr.full_name()
...

>>> get_name_ru()
'Вида Панова'

>>> get_name_ro()
'Veronika Denisova'




>>> from mimesis import Personal
>>> from mimesis.decorators import romanized

>>> pr = Personal('ru')

>>> @romanized('ru')
... def get_name_ro():
...     return pr.full_name()
...

>>> def get_name_ru():
...     return pr.full_name()
...

>>> get_name_ru()
'Вида Панова'

>>> get_name_ro()
'Veronika Denisova'




>>> from mimesis import Personal
>>> from mimesis.decorators import romanized

>>> pr = Personal('ru')

>>> @romanized('ru')
... def get_name_ro():
...     return pr.full_name()
...

>>> def get_name_ru():
...     return pr.full_name()
...

>>> get_name_ru()
'Вида Панова'

>>> get_name_ro()
'Veronika Denisova'
