        Requirements
        =============
        
        - Django (1.11, 2.1) for Django ORM support;
        - Faker >= 0.7.3
        - Flask-SQLALchemy for SQLAlchemy ORM support and integration as Flask application;
        - Mongoengine for Mongoengine ODM support;
        - SQLAlchemy for SQLAlchemy ORM support;
        - Peewee ORM support;
        - fake-factory >= 0.5.0
        - faker == 0.7.3
        - python 2.7 or 3.6+
        
        
        Installation
        =============
        
        **Mixer** should be installed using pip: ::
        
            pip install mixer
        
        
        Usage
        =====
        
         |   By default Mixer tries to generate a fake (human-friendly) data.
         |   If you want to randomize the generated values initialize the Mixer
         |   by manual: Mixer(fake=False)
        
        
         |   By default Mixer saves the generated objects in a database. If you want to disable
         |   this, initialize the Mixer by manual like: Mixer(commit=False)
        
        
        Django workflow
        ---------------
        Quick example: ::
        
            from mixer.backend.django import mixer
            from customapp.models import User, UserMessage
        
            # Generate a random user
            user = mixer.blend(User)
        
            # Generate an UserMessage
            message = mixer.blend(UserMessage, user=user)
        
            # Generate an UserMessage and an User. Set username for generated user to 'testname'.
            message = mixer.blend(UserMessage, user__username='testname')
        
            # Generate SomeModel from SomeApp and select FK or M2M values from db
            some = mixer.blend('someapp.somemodel', somerelation=mixer.SELECT)
        
            # Generate SomeModel from SomeApp and force a value of money field from default to random
            some = mixer.blend('someapp.somemodel', money=mixer.RANDOM)
        
            # Generate 5 SomeModel's instances and take company field's values from custom generator
            some_models = mixer.cycle(5).blend('somemodel', company=(name for name in company_names))
        
        
        Flask, Flask-SQLAlchemy
        -----------------------
        Quick example: ::
        
            from mixer.backend.flask import mixer
            from models import User, UserMessage
        
            mixer.init_app(self.app)
        
            # Generate a random user
            user = mixer.blend(User)
        
            # Generate an userMessage
            message = mixer.blend(UserMessage, user=user)
        
            # Generate an UserMessage and an User. Set username for generated user to 'testname'.
            message = mixer.blend(UserMessage, user__username='testname')
        
            # Generate SomeModel and select FK or M2M values from db
            some = mixer.blend('project.models.SomeModel', somerelation=mixer.SELECT)
        
            # Generate SomeModel from SomeApp and force a value of money field from default to random
            some = mixer.blend('project.models.SomeModel', money=mixer.RANDOM)
        
            # Generate 5 SomeModel's instances and take company field's values from custom generator
            some_models = mixer.cycle(5).blend('project.models.SomeModel', company=(company for company in companies))
        
        
        Support for Flask-SQLAlchemy models that have `__init__` arguments
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        
        For support this scheme, just create your own mixer class, like this: ::
        
            from mixer.backend.sqlalchemy import Mixer
        
            class MyOwnMixer(Mixer):
        
                def populate_target(self, values):
                    target = self.__scheme(**values)
                    return target
        
            mixer = MyOwnMixer()
        
        
        SQLAlchemy workflow
        -------------------
        
        Example of initialization: ::
        
            from mixer.backend.sqlalchemy import Mixer
        
            ENGINE = create_engine('sqlite:///:memory:')
            BASE = declarative_base()
            SESSION = sessionmaker(bind=ENGINE)
        
            mixer = Mixer(session=SESSION(), commit=True)
            role = mixer.blend('package.models.Role')
        
        
        Also, see `Flask, Flask-SQLALchemy`_.
        
        
        Mongoengine workflow
        --------------------
        
        Example usage: ::
        
            from mixer.backend.mongoengine import mixer
        
            class User(Document):
                created_at = DateTimeField(default=datetime.datetime.now)
                email = EmailField(required=True)
                first_name = StringField(max_length=50)
                last_name = StringField(max_length=50)
                username = StringField(max_length=50)
        
            class Post(Document):
                title = StringField(max_length=120, required=True)
                author = ReferenceField(User)
                tags = ListField(StringField(max_length=30))
        
            post = mixer.blend(Post, author__username='foo')
        
        Marshmallow workflow
        --------------------
        
        Example usage: ::
        
            from mixer.main import mixer
            import marshmallow as ma
        
            class User(ma.Schema):
                created_at = ma.fields.DateTime(required=True)
                email = ma.fields.Email(required=True)
                first_name = ma.fields.String(required=True)
                last_name = ma.fields.String(required=True)
                username = ma.fields.String(required=True)
        
            class Post(ma.Schema):
                title = ma.fields.String(required=True)
                author = ma.fields.Nested(User, required=True)
        
            post = mixer.blend(Post, author__username='foo')
        
        
        Common usage
        ------------
        Quick example: ::
        
            from mixer.main import mixer
        
            class Test:
                one = int
                two = int
                name = str
        
            class Scheme:
                name = str
                money = int
                male = bool
                prop = Test
        
            scheme = mixer.blend(Scheme, prop__one=1)
        
        
        DB commits
        ----------
        
        By default 'django', 'flask', 'mongoengine' backends tries to save objects in
        database. For preventing this behavior init `mixer` manually: ::
        
            from mixer.backend.django import Mixer
        
            mixer = Mixer(commit=False)
        
        
        Or you can temporary switch context use the mixer as context manager: ::
        
            from mixer.backend.django import mixer
        
            # Will be save to db
            user1 = mixer.blend('auth.user')
        
            # Will not be save to db
            with mixer.ctx(commit=False):
                user2 = mixer.blend('auth.user')
        
        
        .. _custom:
        
        Custom fields
        -------------
        
        Mixer allows you to define generators for fields by manually.
        
        Quick example: ::
        
                from mixer.main import mixer
        
                class Test:
                    id = int
                    name = str
        
                mixer.register(Test,
                    name=lambda: 'John',
                    id=lambda: str(mixer.g.get_positive_integer())
                )
        
                test = mixer.blend(Test)
                test.name == 'John'
                isinstance(test.id, str)
        
                # You could pinned just a value to field
                mixer.register(Test, name='Just John')
                test = mixer.blend(Test)
                test.name == 'Just John'
        
        Also, you can make your own factory for field types: ::
        
            from mixer.backend.django import Mixer, GenFactory
        
            def get_func(*args, **kwargs):
                return "Always same"
        
            class MyFactory(GenFactory):
                generators = {
                    models.CharField: get_func
                }
        
            mixer = Mixer(factory=MyFactory)
        
        Middlewares
        -----------
        
        You can add middleware layers to process generation: ::
        
            from mixer.backend.django import mixer
        
            # Register middleware to model
            @mixer.middleware('auth.user')
            def encrypt_password(user):
                user.set_password('test')
                return user
        
        You can add several middlewares. Each middleware should get one argument
        (generated value) and return them.
        
        It's also possible to unregister a middleware: ::
        
            mixer.unregister_middleware(encrypt_password)
        
        
        Locales
        -------
        
        By default mixer uses 'en' locale. You could switch mixer default locale by
        creating your own mixer: ::
        
            from mixer.backend.django import Mixer
        
            mixer = Mixer(locale='it')
            mixer.faker.name()          ## u'Acchisio Conte'
        
        At any time you could switch mixer current locale: ::
        
            mixer.faker.locale = 'cz'
            mixer.faker.name()          ## u'Miloslava Urbanov\xe1 CSc.'
        
            mixer.faker.locale = 'en'
            mixer.faker.name()          ## u'John Black'
        
            # Use the mixer context manager
            mixer.faker.phone()         ## u'1-438-238-1116'
            with mixer.ctx(locale='fr'):
                mixer.faker.phone()     ## u'08 64 92 11 79'
        
            mixer.faker.phone()         ## u'1-438-238-1116'
