djhacker 0.1.1

Basic usage

Install with pip install djhacker and then:

import djhacker

djhacker.formfield(
    YourModel.your_field,
    YourFormField,
    custom_form_field_kwarg='something',
)

This will make any Django ModelForm render a YourFormField(custom_form_field_kwarg='something') by default, plus whatever other kwargs it wants to add, you won’t have to use any specific model form, this will work natively in the admin for instance.

Registry

You can register custom form field for model field types:

@djhacker.register(models.ForeignKey)
def custom_fk_formfield(model_field, **kwargs):
    return YourFormField, {
        'custom_form_field_kwarg': 'something',
        **kwargs,
    )

# you don't need to pass extra arguments anymore for ForeignKey fields:
djhacker.formfield(YourModel.some_fk, queryset=Some.objects.all())
