Thanks very much for these responses, they've given me something to
think about.
However, assuming I'm going about things the right way, the problem
appears with the loading of Model data into a Form object which can be
passed to a FormTools.preview class.
For example, in the view function view_post() I thought I'd to have
something like this
view.py
def view_post(request, post_id)
post_obj = get_object_or_404(Post, pk=post_id)
post_form = PostForm(instance=post_obj) # PostForm being a
models.ModelForm
then having something like
return PostFormPreview(post_form)
forms.py
class PostForm(models.ModelForm):
title=fields.CharField(required=False)
body=fields.TextField(required=True)
def save():
...
class PostFormPreview(preview.FormPreview):
def parse_params(self, *args, **kwargs):
...
def done(self, request, cleaned_data):
# The Save() process begins here
But this is were my problems begin. Amongst the comments of formtools/
preview.py:-
class FormPreview(object):
preview_template = 'formtools/preview.html'
form_template = 'formtools/form.html'
# METHODS SUBCLASSES SHOULDN'T OVERRIDE
###################################
def __init__(self, form):
# form should be a Form class, not an instance.
"form should be a Form class, not an instance."
Additionally, in the view_post function in view.py, by returning
PostFormPreview causes the following error:-
AttributeError: 'PostFormPreview' object has no attribute
'status_code'
If I remove the "return" from the view_post, django complains
view_post didn't return a HttpResponse object.
