### Quickstart

Install Django History Actions:

```bash
pip install django-history-events
```

Add it to your `INSTALLED_APPS`:

```python
INSTALLED_APPS = (
...
'history_actions',
...
)

# Define your System Name
HISTORY_ACTIONS_SYSTEM = 'main'
```

Define your actions.py inside your app

```python
# actions.py

from django.utils.translation import ugettext_lazy as _

INFO_TRAINING_SAVE_ACTION = 'INFO_TRAINING_SAVE_ACTION'

ACTIONS = {
'INFO_TRAINING_SAVE_ACTION': _('info trainig save action')
}
```

Now you can track History:

```python
from history_actions.manager import HistoryManager

# log an event
HistoryManager.create(
'an_author', 'INFO_TRAINING_SAVE_ACTION')

# log an event linked to a model
model_instance = ModelKlass.objects.first()
HistoryManager.create(
'an_author', 'INFO_TRAINING_SAVE_ACTION', model_instance=model_instance)

# log an event linked to a model with more info
username = User.ojects.first().username
HistoryActions.create(
'an_author', 'INFO_TRAINING_SAVE_ACTION', model_instance=model_instance, actor=username, notes='My notes')


# log an event linked to a model and serialize the model
username = User.ojects.first().username
model_instance_dict = model_instance.to_dict()
HistoryActions.create(
'an_author', 'INFO_TRAINING_SAVE_ACTION', model_instance=model_instance, actor=username, notes='My notes', extra=model_instace_dict)

# use a different system
HistoryActions.create(
'an_author', 'INFO_TRAINING_SAVE_ACTION', model_instance=model_instance, actor=username, notes='My notes', extra=model_instace_dict, system="custom")
```

If you want to use a diferent system for model tracking, you can define it in:

```python
# models.py

class Chatdentity(MachuBaseModel):
HISTORY_ACTION_SYSTEM = 'chat'

user = models.OneToOneField(User)
user_two = models.OneToOneField(User, related_name='user_manager')
given_name = models.CharField(
'Given Name(s)', max_length=200, default='')
family_name = models.CharField(
'Family Name(s)', max_length=200, default='')
```

### System Name

The system name is taken from:

1. The `create` method `kwargs`.
2. From `HISTORY_ACTIONS_SYSTEM` variable defined in the `settings.py`.
3. The class variable `HISTORY_ACTION_SYSTEM` defined in the model class.

### Signals
