I'm trying to use the formwizard in formtools package with no success (I was able to do it when the package was inside Django in earlier versions).
The only response I got is:
[23/Jan/2016 11:06:50]"GET /registration/wizard HTTP/1.1" 200 13729
and a blank page. No errors in browser or Eclipse console.
There's no way of googling without errors. Please help.
Thanks in advance
What did I do?
Firstly, I installed the formtools package with pip:
django-formtools==1.0
Django==1.8.3
Following the instructions of the official docs:
Define form classes
registration/forms.py
class StepForm1(forms.Form):
first_field = forms.CharField(max_length=100)
second_field = forms.CharField()
class StepForm2(forms.Form):
message = forms.CharField(widget=forms.Textarea)
Create WizardView
registration/views.py
TEST_TEMPLATES = {"test_step_1": "registration/test_step1.html", "test_step_2": "registration/test_step2.html", }
from formtools.wizard.views import SessionWizardView
class WizardTest(SessionWizardView):
template_name = 'registration/test_wizard.html'
# Return templates for each step
def get_templates_name(self):
return [TEST_TEMPLATES[self.steps.current]]
# Method called when all is done
def done(self, form_list, **kwargs):
# return HttpResponseRedirect('/url-to-redirect-to/')
# We return the final template with the info
return render_to_response('test_done.html', {
'form_data':[form.cleaned_data for form in form_list],
})
# THESE METHODS BELOW ARE NOT NEEDED, BUT COMMENTED FOR FUTURE USE
# Not strictly needed. Returns data for a step
# or None if form is not valid
# def get_cleaned_data_for_step(self, step):
# return None
# Form data postprocessing in a concrete wizard step
# def process_step(self, form):
# return self.get_form_step_data(form)
# Handles value from a step before storing them into wizard
# def get_form_step_data(self, form):
# return form.data
Create the templates
registration/test_step1.html
<h1>Two fields form</h1>
<input id="first_field" name="first_field">
<input id="second_field" name="second_field">
registration/test_step2.html
<h1>Message form</h1>
<input id="message" name="message">
registration/test_wizard.html
{% extends "person/alumnos.html" %}
{% load i18n %}
{% block head %}
{{ wizard.form.media }}
{% endblock head %}
{% block content %}
<p>{% trans "Step {{wizard.steps.step1}} of {{wizard.steps.count}}" %}</p>
<form action="" method="post">
{% csrf_token %}
{{ wizard.management_form }}
{% if wizard.form.forms %}
{{ wizard.form.management_form }}
{% for form in wizard.form.forms %}
{{form}}
{% endfor %}
{% else %}
{{ wizard.form }}
{% endif %}
{% if wizard.steps.prev %}
<button name="wizard_goto_step" type="submit" value="{{ wizard.steps.first }}">{% trans "Beginning" %}</button>
<button name="wizard_goto_step" type="submit" value="{{ wizard.steps.prev }}">{% trans "Previous step" %}</button>
{% endif %}
<input type="submit" value="submit"/>
</form>
{% endblock %}
Add 'formtools' to my INSTALLED_APPS

INSTALLED_APPS = DJANGO_APPS + LOCAL_APPS
registration/urls.py
from registration.forms import StepForm1, StepForm2
TEST_FORMS = [("test_step_1", StepForm1), ("test_step_2", StepForm2), ]
from registration.views import WizardTest
# I tried in two ways, none of them worked
urlpatterns = patterns('',
url(r'^wizard$', WizardTest.as_view(TEST_FORMS), name='wizard_test'),
url(r'^wizard2$', views.wizard, name='wizard_test'),
)
For the second way...
registration/views.py
def wizard(request):
return WizardTest.as_view(TEST_FORMS)(request)
I found my error. I typed badly the method name for getting the templates. It's not
get_templates_name(self)
but
get_template_names(self)
It wasn't getting any templates, but when returning to server it was answering with HTTP 200 OK, because it didn't found any error.
I also found that my templates for every step should extend the main wizard template in order to work correctly. With the 'done' template is not necessary.
