'Addons for Django Formtools'
Project description
‘Addons for Django Formtools’
Features
Add multiple forms to a single WizardView step (MultipleFormWizardView and subclasses)
Use form wizard via JSON web API (WizardAPIView)
Quickstart
Install formtools-addons:
pip install django-formtools-addons
Then use it in a project:
# Every *MultipleForm* WizardView that can be imported is an equivalent of a builtin *WizardView in Django Formtools from formtools_addons import (SessionMultipleFormWizardView, CookieMultipleFormWizardView, NamedUrlSessionMultipleFormWizardView, NamedUrlCookieMultipleFormWizardView, MultipleFormWizardView, NamedUrlMultipleFormWizardView) # The WizardAPIView is also based on the builtin WizardView, but does not have the classic request-response cycle, # since it exposes a JSON API from formtools_addons import WizardAPIView
WizardAPIView: Example use
from __future__ import unicode_literals
from formtools_addons import WizardAPIView
from .forms import Form1, Form2, Form3, Form4
def show_substep_4(wizard):
cleaned_data = wizard.get_cleaned_data_for_step('my-page1|my-substep-1') or {}
return cleaned_data.get('some_field', None) != 'some_value'
class TestWizardAPIView(WizardAPIView):
form_list = [
("my-page1", (
("my-substep-1", Form1),
("my-substep-2", Form2),
("my-substep-3", Form3)
)),
("my-page2", (
('my-substep-4', Form4),
))
]
condition_dict = {
'my-page2|my-substep-4': show_substep_4,
}
form_templates = {
"my-page1|my-substep-1": 'demo/page1_substep1.html',
"my-page2|my-substep-4": 'demo/page2_substep4.html',

"my-page1|my-substep-1": 'demo/page1_substep1_preview.html',
"my-page2|my-substep-4": 'demo/page2_substep4_preview.html',
}
def render_form(self, step, form):
# Get preview template url
template_url = self.form_templates.get(step, None)
if template_url is None:
data = form.cleaned_data
return '<p>NO TEMPLATE: STEP: %s, DATA: %s</p>' % (
step, json.dumps(data, default=self.json_encoder.default))
# Load template
template = get_template(template_url)
# Create context
context = Context()
context['form'] = form
return template.render(context)
def render_preview(self, step, form):
if not form.is_bound or not form.is_valid():
return
# Get preview template url
template_url = self.preview_templates.get(step, None)
if template_url is None:
data = form.cleaned_data
return '<p>NO TEMPLATE: STEP: %s, DATA: %s</p>' % (
step, json.dumps(data, default=self.json_encoder.default))
# Load template
template = get_template(template_url)
# Create context
context = Context()
context['data'] = form.cleaned_data if (form.is_bound and form.is_valid()) else {}
return template.render(context)
