Hi,
Here is what I am trying to do. Get the root folder name in form 1 and list
the found sub directories (matching a pattern) and give an
option for user to select the sub dirs. Once selected, I want to save the
model.
1. How to dynamically display found sub directories in form 2. I have
defined a method (def _findSubs) in views.py
2. I have split a model into 2 forms. How to save the data fetched from 2
forms into one model.
3. I have read the docs. But couldn't figure out where to put
WizardView.get_form_initial() method. My knowledge with Django is very
trivial.
Here is what I am doing.
--------------------
models.py
-------------------
from django.db import models
class Tree(models.Model):
rootDir = models.CharField(max_length=100) # will be populated using
form 1
subDirs = models.CharField(max_length=100) # will be populated using
form 2
def __unicode__(self):
return u'%s %s' % (self.rootDir, self.subDir)
-------------------
forms.py
-------------------
from django import forms
from myapp.models import Tree
class MainForm(forms.ModelForm):
class Meta:
model = Tree
exclude = ('subDirs')
class SecondForm(forms.Form):
SUBDIRS = # _findSubs result should be here.
SELECTED =
forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, choices =
SUBDIRS)
--------------------
views.py
-------------------
from django.shortcuts import render
from django.http import HttpResponseRedirect
from django.contrib.formtools.wizard.views import SessionWizardView
from myapp.forms import MainForm, SecondForm
FORMS = [("main", MainForm), ("select", SecondForm)]
TEMPLATES = {"main": "main.html", "select": "select.html"}
class FormWizard(SessionWizardView):
def get_template_names(self):
return [TEMPLATES[self.steps.current]]
def done(self, form_list, **kwargs):
# Now save Model here. HOW??
pass
def main(request):
if request.method == 'POST':
http_req_type = request.method
mainform = MainForm(request.POST)
if mainform.is_valid():
cd = mainform.cleaned_data
tree = cd['rootDir']
subdirs = _findSubs(tree)
else:
http_req_type = request.method
mainform = MainForm()
return render(request, 'main.html', locals())
def selection(request):
if request.method == 'POST':
http_req_type = request.method
selectionform = SecondForm(request.POST)
if selectionform.is_valid():
cd = selectionform.cleaned_data
subdirs = selectionform.cleaned_data.get('SELECTED')
return HttpResponseRedirect('/done/')
else:
http_req_type = request.method
form = SecondForm()
return render(request, 'select.html', {'form':form })
def _findSubs(tree):
''' Return a list of sub directory matching the pre-defined patter
'''
# some logic here. Don't worry abt it.
return subs
-------------------
urls.py
-------------------
from myapp import views
url(r'^main/', views.FormWizard.as_view(views.FORMS)),
