django-fieldmaker - Form Creator for Django

version

alpha

Introduction

This package enables you to design forms in the Django admin. These forms can be used in your code or to extend existing forms in the admin itself. Other libraries may register new fields or widgets for the designer to use.

You may install using pip or easy_install:

pip install django-fieldmaker

To use you first have to add fieldmaker to INSTALLED_APPS, and then execute syncdb to create the tables.

Using Expandable Forms

ExpandableForm and ExpandableModelForm allow you to define forms and have the user expand those forms through the admin. The form will add any fields defined in the form definition having the form_key specified in the Meta. The ExpandableModelForm will additionally save the extra information and associate it to the instance.

Example usage:

from django import forms
from fieldmaker.forms import ExpandableForm, ExplandableModelForm
from myapp.models import MyModel

class MyForm(ExpandableForm):
    title = forms.CharField()

    class Meta:
        form_key = 'myform'

class MyModelForm(ExpandableModelForm):
    class Meta:
        model = MyModel
        form_key = 'mymodel'

Extending Your Admin

ExpandableModelAdmin allows for forms in the admin to have fields dynamically defined and added to them. If a ModelAdmin that inherits from this class is registered in the admin, then creating a form definition with the key <app_label>_<object_name> and adding fields will add fields you your admin.

Adding a form definition using the admin with the key "myapp_mymodel" would add dynamically fields to the MyModel admin below:

from django.contrib import admin
from fieldmaker.admin import ExpandableModelAdmin

from myapp.models import MyModel

class MyModelAdmin(ExpandableModelAdmin):
    pass

admin.site.register(MyModel, MyModelAdmin)

Extending Fieldmaker

To register a new field:

from fieldmaker.fields import BaseFieldForm, BaseField
from fieldmaker.resources import field_registry

class URLFieldForm(BaseFieldForm):
    max_length = forms.IntegerField(required=False)
    min_length = forms.IntegerField(required=False)
    verify_exits = forms.BooleanField(initial=False, required=False)
    validator_user_agent = forms.CharField(required=False)

class URLField(BaseField):
    form = URLFieldForm
    field = forms.URLField
    identities = ['URLField']

field_registry.register_field('URLField', URLField)

To register a new widget:

from fieldmaker.widgets import BaseWidgetForm, BaseWidget
from fieldmaker.resources import field_registry

class PasswordInputWidgetForm(BaseWidgetForm):
    render_value = forms.BooleanField(required=False, initial=True)

class PasswordInput(BaseWidget):
    widget = widgets.PasswordInput
    identities = ['CharField']

field_registry.register_widget('PasswordInput', PasswordInput)
