# Django Administration JSON Editor

[](https://travis-ci.org/abogushov/django-admin-json-editor)



Application adds support for editing JSONField in Django Administration via https://github.com/jdorn/json-editor.

## Quick start

Install application via pip:

```bash
pip install django-admin-json-editor
```

Add application to the INSTALLED_APPS settings:

```python
INSTALLED_APPS = [
...
'django_admin_json_editor',
...
]
```

Define schema of json field:

```python
DATA_SCHEMA = {
'type': 'object',
'title': 'Data',
'properties': {
'text': {
'title': 'Some text',
'type': 'string',
'format': 'textarea',
},
'status': {
'title': 'Status',
'type': 'boolean',
},
},
}
```

Use JSONEditorWidget to bind editor to the form field:

```python
class JSONModelAdminForm(forms.ModelForm):
class Meta:
model = JSONModel
fields = '__all__'
widgets = {
'data': JSONEditorWidget(DATA_SCHEMA, collapsed=False),
}
```

### Dynamic schema

It is possible to build dynamic schema for widget:

```python
def dynamic_schema(widget):
return {
'type': 'array',
'title': 'tags',
'items': {
'type': 'string',
'enum': [i for i in Tag.objects.values_list('name', flat=True)],
}
}
```

```python
@admin.register(JSONModel)
class JSONModelAdmin(admin.ModelAdmin):
def get_form(self, request, obj=None, **kwargs):
widget = JSONEditorWidget(dynamic_schema, False)
form = super().get_form(request, obj, widgets={'tags': widget}, **kwargs)
return form
```
