Using Django Model Forms + Form Wizard + Crispy - doesn't go to second step
I am new to forms in django.
My problem is that I have some very large models that I have to break down into several small forms for users to fill out.
So I was playing with crispy shapes and yesterday after watching Mike Hibbert's tutorial (Python Django tutorial 19 - Using the Wizard) on youtube I wanted to see if I could make this work with crispy shapes.
Everything seems to be looking good, but when I click the submit button, the form appears to be submitted, but does not proceed to step 2.
Am I doing it completely wrong?
Thanks for any help or suggestions!

For anyone in the future, I think I have solved my problem. It took a little time for me to figure it out, but my persistent tinkering is paying off. I wish I had gone into the details of what I had to change, but I'm sure most of you can see the changes from the code I posted. the shapes look great! The session wizard works as expected! and everything seems to be in order. Good luck everyone!

I think I solved the problem a bit, or maybe just got lucky.
In forms.py where meta () fields = '__ all __'
need to be changed to reflect the areas of interest, i used the variable Sheet1_layout and Sheet2_layout. After that, the wizard seems to move on to the next step.
forms.py
from django import forms
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit, Layout, ButtonHolder
from crispy_forms.bootstrap import StrictButton
from models import ProcessSheet
Sheet1_layout = (
'sheet_id',
'sheet_title',
'part_name',
)
class Sheet1(forms.ModelForm):
def __init__(self, *args, **kwargs):
print "sheet 1 init!!!!!!!!!!!!!!!"
super(Sheet1, self).__init__(*args, **kwargs)
# If you pass FormHelper constructor a form instance
# It builds a default layout with all its fields
self.helper = FormHelper(self)
self.helper.form_tag = False
self.helper.form_class = 'form-horizontal'
self.helper.label_class = 'text-center col-lg-4'
self.helper.field_class = 'col-lg-8'
self.helper.layout = Layout(Sheet1_layout,
ButtonHolder('save', css_class='btn-warning'),
)
self.helper.layout.append(Submit('save', 'Save'))
class Meta:
model = ProcessSheet
fields = Sheet1_layout
Sheet2_layout = (
'cooling',
'nozzle',
'zone_5',
)
class Sheet2(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(Sheet2, self).__init__(*args, **kwargs)
# If you pass FormHelper constructor a form instance
# It builds a default layout with all its fields
self.helper = FormHelper(self)
self.helper.form_tag = False
self.helper.form_class = 'form-horizontal'
self.helper.label_class = 'text-center col-lg-4'
self.helper.field_class = 'col-lg-8'
self.helper.layout = Layout(Sheet2_layout,
ButtonHolder('finish', css_class='btn-warning'),
)
self.helper.layout.append(Submit('save', 'Finish'))
class Meta:
model = ProcessSheet
fields = Sheet2_layout
class TestSheet1(forms.Form):
sheet_id = forms.CharField(max_length=16)
class TestSheet2(forms.Form):
hello = forms.CharField(max_length=16)
