I am sure that I have read everything there is available in the
newsgroup and docs concerning uploading files.
If I missed something I apologize in advance.
Right now all I am trying to do is upload a file and use the
manipulator to validate that it is not missing. Everything seems to be
working except when I call the manipulator.get_validation_errors
method. It throws an exception (see traceback below).
If I don't update the new_data dictionary with request.FILES then I get
a 'This field is required.' error.
I commented out the method call and did verify that the file was
uploaded to the view.
Any help would be most appreciated.
I am using Django 0.95
-----------------------------------------
View:
-----------------------------------------
def upload_album(request):
manipulator = AlbumUploadManipulator()
if request.POST:
new_data = request.POST.copy()
# if this if statement is commented out then
# 'error_dict': {'album_file': ['This field is required.']}
if request.FILES:
new_data = new_data.update(request.FILES)
# exception gets thrown here
errors = manipulator.get_validation_errors(new_data)
if not errors:
<snip>
return HttpResponseRedirect("/albums/")
else:
errors = new_data = {}
form = forms.FormWrapper(manipulator, new_data, errors)
return render_to_response('upload_form.html', {'form': form})
-----------------------------------------
Manipulator:
-----------------------------------------
from django import forms
class AlbumUploadManipulator(forms.Manipulator):
def __init__(self):
self.fields = (
forms.TextField(field_name="album_name",
length=30, maxlength=200,
is_required=True),
forms.FileUploadField(field_name="album_file",
is_required=True),
)
------------------------------------------
Template:
------------------------------------------
<form method="post" action="." enctype="multipart/form-data">
