Hello everybody.
I am a Django newbie experimenting with some stuff. I am very
impressed by the framework, that made me want to learn more about it.
I am trying to do some file upload but I have a problem.
I tried many information sources but could not find a simple example
of what I am trying to do. I have a few question...
Well, It should be very simple, I just want to upload a file on the
server on the MEDIA directory.
I use the up to date SVN version ( 5156 ).
I put sipets of code below, the things I dont anderstand are:
* The {{form.updateFile_file}} tag produces nothing the first time I
load my page. Is it normal behavior?
* The validation raises an AttributeError with message: 'dict' object
has no attribute 'startswith'
The lower part of the stack is :
/home/guillaume/dev/Python/django_src/django/db/models/fields/
__init__.py in isWithinMediaRoot
628. # If the raw path is passed in, validate it's under the
MEDIA_ROOT.
629. def isWithinMediaRoot(field_data, all_data):
630. f = os.path.abspath(os.path.join(settings.MEDIA_ROOT,
field_data)) ...
631. if not
f.startswith(os.path.abspath(os.path.normpath(settings.MEDIA_ROOT))):
632. raise validators.ValidationError, _("Enter a valid filename.")
* If I disable the validation, I have an error because Django tries to
insert the file data into the database as a string...
Well I probably missed something very simple, but I cannot figure
it ...
Might a Django Guru engilten me ?
Yours,
Guillaume.

My model :
#-----------------------------------------------------------------------------
class StockUpdateFile( models.Model ):
updateFile = models.FileField( upload_to = 'updatefiles/%Y/%m/
%d' )
fdate = models.DateField( auto_now_add = True )
def __str__( self ):
return "file %1-%2-%3" % str( distributor ) % str( fdate ) %
str( updateFile )
class Admin:
pass
--------------------------------------------------------------------------------------------------------------
The form is:
class UploadForm( forms.Form ):
updateFile = forms.Field( widget = forms.FileInput() )
----------------------------------------------------------------------------------------------------------------
My template is:
<form enctype="multipart/form-data" action="/stock/uploadfile/"
method="post" >
<table>
{{form.updateFile}}:{{form.updateFile_file}}
</table>
<input type="submit" value="Upload File" />
</form>
-----------------------------------------------------------------------------------------------------------------
And the code handling the form is:
def uploadFile(request, template='uploadfile.html' ):
errors = {}
form = UploadForm()
if( request.FILES ):
manip = StockUpdateFile.AddManipulator()
newData = request.POST.copy()
newData.update( request.FILES )
errors = manip.get_validation_errors( newData )
if( not errors):
manip.do_html2python( newData )
newFile = manip.save( newData )
else:
form = UploadForm()
return render_to_response( template,
context_instance =
RequestContext( request, {'form': form,
'errors' : errors } ))
