Hey everyone,
I have brought up this issue before, and I was able to fix a few
things but I am still having a lot of problems. I have a model with a
filefield, and i was testing it with the development server and it
worked perfectly. When I tried to copy it into the working server is
when I started having problems.
The following is the model:
class BulkDataRegFile(models.Model):
"""DataProviders can register their data sets in large amounts
without having to enter the information into the same form
several times.
This class takes a file field that uploads the file to the
system server and then reads the file and places the data
into the database for use by others
"""
user = models.ForeignKey(User, blank = False)
domain = models.ForeignKey(DataDomain, blank = False)
bulk = models.FileField(upload_to = 'bulk/', unique = True)
def __str__(self):
return self.bulk
def save(self):
super(BulkDataRegFile, self).save()
import ConfigParser
config = ConfigParser.ConfigParser()
file = get_bulk_filename()
config.readfp(open(file))
sec = config.sections()
for i in sec:
set_name = i
it = config.items(i)
for k in it:
tag = k[0]
if tag == 'url':
url = k[1]
elif tag == 'type':
type1 = k[1]
elif tag == 'end_date':
end = k[1]
elif tag == 'start_date':
start = k[1]
elif tag == 'metadata':
meta = k[1]
if type1 == 'timeseries':
type1 = 0
else:
type1 = 1
univ = '%s.%s' % (domain.get_udi_prefix(), set_name)
b = DataSet(domain = self.domain,
data_set_type = type1,
udi = univ,
start_time = start,
end_time = end,
metadata = meta,
server_url = url,)
b.save()
class Admin: pass
I updated the database to add the table and synced it. Now I go into
the Admin and try to upload a file through the admin interface and I
get the following error:
Traceback (most recent call last):

189. config.readfp(open(file))
IOError at /admin/vidars/bulkdataregfile/add/
[Errno 2] No such file or directory: ''
I have no idea what to do from here, for some reason it wont actually
save the file to the directory I specified if i configured it
correctly, which i am still not sure about.
MEDIA_ROOT = '/var/www/media/'
MEDIA_URL = 'https://vidars.sr.unh.edu/media/'
media is a symbolic link to the media file in my app which contains
all the css and images, so the apache server is serving those. other
than that i dont know what to do.
I am wondering if it is at a django level because when i get the
traceback it gives me the values of the variables being used and the
field 'bulk' doesnt get an id like the following.

this shows me that it grabs the value of the file i uploaded but its
not saving it to the database correctly and its not actually saving
the contents of the file to the server . so if any one has any
suggestions i would greatly appreciate it becuase this is a huge wall
that i have hit and can't seem to get past it no matter what i
research or try.
Thanks for your time!
