# Wagtail Orderable

Simple orderable mixin to add drag-and-drop ordering support to the `ModelAdmin` listing view.

It attempts to provide the [feature request](https://github.com/wagtail/wagtail/issues/2941) in Wagtail project without modifying the project code as it seems not a high priority item for the project.

### Installation

Install the package
```
pip install wagtail-orderable
```

### Settings
In your settings file, add `wagtailorderable` to `INSTALLED_APPS`:
```python
INSTALLED_APPS = [
    # ...
    'wagtailorderable',
    # ...
]
```

### Usage

#### Extend with `Orderable` (optional)

To apply the orderable feature, you can extend your model with `Orderable` which will add
a `sort_order` `IntegerField` to your model but if you already have a field to store
an index value, **this is not required**.

```python
from django.db import models

from wagtailorderable.models import Orderable

class YourModel(Orderable):
    title = models.CharField(max_length=200)
```

Of course you can apply it to Wagtail's `Page` model.
```python
from wagtail import fields
from wagtail.models import Page

from wagtailorderable.models import Orderable

class YourModel(Page, Orderable):
    description = fields.RichTextField(blank=True)
```

Or just use your model with your personal ordering field.

```python
from django.db import models

class YourOtherModel(models.Model):
    title = models.CharField(max_length=200)
    my_custom_order_field = models.IntegerField(null=False, blank=True, default=0, editable=False)
```

Note that `Orderable` also exists in `wagtail.models`, **DO NOT** use that as the mixins require the model from the same package.

To apply the feature support in admin panel. In `wagtail_hooks.py`:
```python
from wagtail.contrib.modeladmin.options import (
    ModelAdmin, modeladmin_register)

from wagtailorderable.modeladmin.mixins import OrderableMixin

from .models import YourModel, YourOtherModel

class YourModelAdmin(OrderableMixin, ModelAdmin):
    model = YourModel

class YourOtherModelAdmin(OrderableMixin, ModelAdmin):
    model = YourOtherModel
    sort_order_field = 'my_custom_order_field'

modeladmin_register(YourModelAdmin)
modeladmin_register(YourOtherModelAdmin)
```

Note that `sort_order_field` is optional if you extend your model with `Orderable`
or if your Model has a `sort_order_field` attribute.

Finally, collect the corresponding static file by running
```shell
python manage.py collectstatic
```
in your project.

### Acknowledgement
Most of the contribution comes from this [commit](https://github.com/rkhleics/wagtail/commit/08df07689af1096ce4a6fa96325dbfb7fab9240d) which attempts to integrate the solution in Wagtail project. Though it is not being used in Wagtail now it provides great skeleton for the feature which helps me created this mixin.

Thanks the contribution from [Andy Babic](https://github.com/ababic).
