## Dependencies

* [MySQL][mysql] (or compatible)
* [PostgreSQL][postgresql]

## Installation

<pre>
<a href="https://.com">pip</a> install <a href="https://pypi.org/project/django-add-default-value/">django-add-default-value</a>
</pre>

You can then use `AddDefaultValue` in your migration file to transfer the default
values to your database. Afterwards, it’s just the usual `./manage.py migrate`.

## Usage

```python
AddDefaultValue(
model_name='my_model',
name='my_field',
value='my_default'
)
```

### Example

Given the following migration:

```python
operations = [
migrations.AddField(
field=models.CharField(default='my_default', max_length=255),
model_name='my_model',
name='my_field',
),
]
```

Modify the migration to add a default value:

```diff
+from django_add_default_value import AddDefaultValue
+
operations = [
migrations.AddField(
field=models.CharField(default='my_default', max_length=255),
model_name='my_model',
name='my_field',
),
+ AddDefaultValue(
+ model_name='my_model',
+ name='my_field',
+ value='my_default'
+ )
]
```

If you check `python manage.py sqlmigrate [app name] [migration]`,
you will see that the default value now gets set.
