Django Populate
===============

*Django Populate* uses the `faker`_ package to generate test data for Django models and templates.

How to use
----------

To install Django Populate you can use pip::

    pip install django-populate


Configuration
~~~~~~~~~~~~~

In django application `settings.py`::

    INSTALLED_APPS = (

        # ...
        'django_populate',
    )

    FAKER_LOCALE = None     # settings.LANGUAGE_CODE is loaded
    FAKER_PROVIDERS = None  # faker.DEFAULT_PROVIDERS is loaded (all)


Populating Django Models
~~~~~~~~~~~~~~~~~~~~~~~~

*django-populate* provides an adapter for Django Models, for easy population of test databases.
To populate with Model instances, create a new Populator class,
then list the class and number of all of Models that must be generated. To launch the actual data population,
call `execute()` method.

Here is an example showing how to populate 5 `Game` and 10 `Player` objects::

    from django_populate import Faker
    # this Populator is only a function thats return a django_populate.populator.Populator instance
    # correctly initialized with a faker.generator.Generator instance, configured as above
    populator = Faker.getPopulator()

    from myapp.models import Game, Player
    populator.addEntity(Game,5)
    populator.addEntity(Player,10)

    insertedPks = populator.execute()

The populator uses name and column type guessers to populate each column with relevant data.
For instance, django-populate populates a column named `first_name` using the `firstName` formatter, and a column with
a `datetime` instance using the `dateTime`.
The resulting entities are therefore coherent. If django-populate misinterprets a column name, you can still specify a custom
function to be used for populating a particular column, using the third argument to `addEntity()`::


    populator.addEntity(Player, 10, {
        'score':    lambda x: populator.generator.randomInt(0,1000),
        'nickname': lambda x: populator.generator.email(),
    })
    populator.execute()

Of course, django-populate does not populate autoincremented primary keys.
In addition, `django_populate.populator.Populator.execute()` returns the list of inserted PKs, indexed by class::

    print insertedPks
    {
        <class 'faker.django.tests.Player'>: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
        <class 'faker.django.tests.Game'>: [1, 2, 3, 4, 5]
    }

In the previous example, the `Player` and `Game` models share a relationship. Since `Game` entities are populated first,
Faker is smart enough to relate the populated `Player` entities to one of populated `Game` entities.


Template tags and filter
~~~~~~~~~~~~~~~~~~~~~~~~

django-populate offers a useful template tags and filters for interact with `PyFaker`_::

    {% fake 'name' as myname %}{% fake 'dateTimeBetween' '-10d' as mydate %}

    {{ myname|title }} - {{ mydate|date:"M Y" }}



    {% load fakers %}

    <?xml version="1.0" encoding="UTF-8"?>
    <contacts>
        {% fake 'randomInt' 10 20 as times %}
        {% for i in 10|get_range %}
        <contact firstName="{% fakestr 'firstName' %}" lastName="{% fakestr 'lastName' %}" email="{% fakestr 'email' %}"/>
            <phone number="{% fakestr 'phoneNumber' %}"/>
            {% if 'boolean'|fake:25 %}
            <birth date="{{ 'dateTimeThisCentury'|fake|date:"D d M Y" }}" place="{% fakestr 'city' %}"/>
            {% endif %}
            <address>
                <street>{% fakestr 'streetAddress' %}</street>
                <city>{% fakestr 'city' %}</city>
                <postcode>{% fakestr 'postcode' %}</postcode>
                <state>{% fakestr 'state' %}</state>
            </address>
            <company name="{% fakestr 'company' %}" catchPhrase="{% fakestr 'catchPhrase' %}">
            {% if 'boolean'|fake:25 %}
                <offer>{% fakestr 'bs' %}</offer>
            {% endif %}
            {% if 'boolean'|fake:33 %}
                <director name="{% fakestr 'name' %}" />
            {% endif %}
            </company>
            {% if 'boolean'|fake:15 %}
            <details>
            <![CDATA[
            {% fakestr 'text' 500 %}
            ]]>
            </details>
            {% endif %}
        </contact>
        {% endfor %}
    </contacts>


Page preview
~~~~~~~~~~~~
Open `url.py` in your main application and add this url::

    urlpatterns = patterns('',
        ...
        url(r'', include('django_populate.urls')),
        ...
    )

http://127.0.0.1:8000/preview/ shows a faked browser windows, useful for screenshots.

Running the Tests
-----------------

Run django tests in a django environment:

    $ python runtests.py

or if you have 'django_populate' in INSTALLED_APPS:

    $ python manage.py test django_populate
