I have a form to add new rows to my database which is working fine,
and I'm
trying to add a file upload field to it. I'm following the Movie
tutorial,
with a few changes. (My main table is CorpusText, and the filenames go
in a
related table named File, since each text can have multiple associated
files. The actual file is saved in a folder, not in the database.)
I've got it half working: the form field is working fine, and the
filename
is successfully added to the database. The problem comes up when I
added
the code to actually save the file to the folder where it should be; I
get
the error: *"TypeError: 'unicode' object is not callable."
*The files that I'm working with are all in Arabic, and so are 'utf-8'
text
files. (I assume that this is where the problem is, since the tutorial
is made for an image file.)
I've searched on Google and haven't found any solutions... Any ideas?
Thanks,
Karen
PS - I started out using Widgets and Sprox and trying it all that
way, but
was having too many problems. That's why I'm just doing a plain HTML
form.
