Django better admin ArrayField

Better ArrayField widget for admin

Supported Python versions:

Supported Django versions: 2.0, 2.1, 2.2, 3.0, 3.1

might work with different django/python versions as well but I did not test that.

It changes comma separated widget to list based in admin panel.

Quickstart

Install Django better admin ArrayField:

pip install django-better-admin-arrayfield

Add it to your `INSTALLED_APPS`:

INSTALLED_APPS = (
    ...
    'django_better_admin_arrayfield',
    ...
)

Usage

django_better_admin_arrayfield.models.fields.ArrayField is a drop-in replacement for standard Django ArrayField.

Import it like below and use it in your model class definition.

from django_better_admin_arrayfield.models.fields import ArrayField

Import DynamicArrayMixin like below

from django_better_admin_arrayfield.admin.mixins import DynamicArrayMixin

In your admin class add DynamicArrayMixin: ...

class MyModelAdmin(admin.ModelAdmin, DynamicArrayMixin):

That's it.

Custom subwidget

By default the subwidget (the one used for each item in the array) will be TextInput. If you want something else, you can use your own specifying it in the formfield_overrides of your Admin model:

class MyWidget(DynamicArrayWidget):
    def __init__(self, *args, **kwargs):
        kwargs['subwidget_form'] = MyForm
        super().__init__(*args, **kwargs)

class MyModelAdmin(models.ModelAdmin, DynamicArrayMixin):
    ...
    formfield_overrides = {
        DynamicArrayField: {'widget': MyWidget},
    }

If you wanted to have Textarea as the subwidget, you can simply use the included drop-in widget replacement:

from django_better_admin_arrayfield.forms.widgets import DynamicArrayTextareaWidget

class MyModelAdmin(models.ModelAdmin, DynamicArrayMixin):
    ...
    formfield_overrides = {
        DynamicArrayField: {'widget': DynamicArrayTextareaWidget},
    }
