e3-django-dynamic-forms 0.1.3

A dynamic JSON-based form engine for Django

e3-django-dynamic-forms

A dynamic JSON-based form engine for Django. Staff design form schemas via a visual web UI, those schemas render server-side as Django forms, and responses are stored as JSON.

Installation

pip install e3-django-dynamic-forms

Quick Setup

1. Add to INSTALLED_APPS:

INSTALLED_APPS = [
    # ...
    'rest_framework',
    'e3_dynamic_forms',
]

2. Include URLs:

urlpatterns = [
    path('dynamic-forms/', include('dynamic_forms.urls')),
]

3. Run migrations:

python manage.py migrate

4. Visit /dynamic-forms/schemas/ to start designing forms.

Templates

The package ships with a built-in base template (dynamic_forms/base.html) so it works out of the box — no need to provide your own base.html.

To use your project's base template instead, set BASE_TEMPLATE in your settings:

DYNAMIC_FORMS = {
    'BASE_TEMPLATE': 'my_project/base.html',
}

The only requirement is that your base template defines a {% block content %} block, which is where all dynamic form pages render their content.

Settings

All settings go in a DYNAMIC_FORMS dict in your Django settings:

DYNAMIC_FORMS = {
    'BASE_TEMPLATE': 'dynamic_forms/base.html',       # Template to extend (default: built-in)
    'FIELD_AGENT_CHECK': 'myapp.utils.is_agent',      # Custom field agent check
    'USER_ADMIN_UNIT': 'myapp.utils.get_admin_unit',   # Custom admin unit getter
    'ADMIN_UNIT_MODEL': 'myapp.AdminUnit',             # Admin unit model (optional)
    'STAFF_PERMISSION_MIXIN': 'dynamic_forms.permissions.IsStaffMemberMixin',
    'FIELD_AGENT_PERMISSION_MIXIN': 'dynamic_forms.permissions.IsFieldAgentUserMixin',
}

Swappable Attachment Model

Like AUTH_USER_MODEL, you can swap the attachment model:

# settings.py
DYNAMIC_FORMS_ATTACHMENT_MODEL = 'myapp.MyAttachment'

# myapp/models.py
from dynamic_forms.models import AbstractAttachment

class MyAttachment(AbstractAttachment):
    extra_field = models.CharField(max_length=255)

    class Meta(AbstractAttachment.Meta):
        swappable = 'DYNAMIC_FORMS_ATTACHMENT_MODEL'

                        ]
                    }
