django-any-urlfield 1.0.1

An improved URL selector to choose between internal models and external URLs

django-any-urlfield

The any_urlfield module provides an improved URL selector that supports both URLs to internal models and external URLs.

This addresses is a common challenge in CMS interfaces; where providing a URLField makes it hard to enter internal URLs, while providing a ModelChoiceField makes it too inflexible. This package provides the both of both worlds.

Relevant public classes:

• Model fields:

• AnyUrlField: allow users to choose either a model or external link as URL value

• Form widget rendering:

• HorizonatalRadioFieldRenderer

• SimpleRawIdWidget

For more details, see the documentation at Read The Docs.

Installation

First install the module, preferably in a virtual environment. It can be installed from PyPI:

pip install django-any-urlfield

Or the current folder can be installed:

pip install .

Configuration

Add the module to the installed apps:

INSTALLED_APPS += (
    'any_urlfield',
)

Usage

In a Django model, the field can be included:

from django.db import models
from any_urlfield.models.fields import AnyUrlField

class MyModel(models.Model):
    title = models.CharField("Title", max_length=200)
    url = AnyUrlField("URL")

By default, the AnyUrlField only supports linking to external pages. To add support for your own models (e.g. an Article model), include the following code in models.py:

from any_urlfield.models import AnyUrlField
AnyUrlField.register_model(Article)

Now, the AnyUrlField offers users a dropdown field to directly select an article. By default, it uses a django.forms.models.ModelChoiceField field with a django.forms.widgets.Select widget to render the field. This can be customized using the form_field and widget parameters:

from any_urlfield.models import AnyUrlField
from any_urlfield.forms.widgets import SimpleRawIdWidget

AnyUrlField.register_model(Article, widget=SimpleRawIdWidget(Article))

Now, the Article model will be displayed as raw input field with a browse button.
