Django forms I cannot save picture file
i have the model:
class OpenCv(models.Model):
created_by = models.ForeignKey(User, blank=True)
first_name = models.CharField(('first name'), max_length=30, blank=True)
last_name = models开发者_StackOverflow中文版.CharField(('last name'), max_length=30, blank=True)
url = models.URLField(verify_exists=True)
picture = models.ImageField(help_text=('Upload an image (max %s kilobytes)' %settings.MAX_PHOTO_UPLOAD_SIZE),upload_to='jakido/avatar',blank=True, null= True)
bio = models.CharField(('bio'), max_length=180, blank=True)
date_birth = models.DateField(blank=True,null=True)
domain = models.CharField(('domain'), max_length=30, blank=True, choices = domain_choices)
specialisation = models.CharField(('specialization'), max_length=30, blank=True)
degree = models.CharField(('degree'), max_length=30, choices = degree_choices)
year_last_degree = models.CharField(('year last degree'), max_length=30, blank=True,choices = year_last_degree_choices)
lyceum = models.CharField(('lyceum'), max_length=30, blank=True)
faculty = models.ForeignKey(Faculty, blank=True,null=True)
references = models.CharField(('references'), max_length=30, blank=True)
workplace = models.ForeignKey(Workplace, blank=True,null=True)
the form:
class OpencvForm(ModelForm):
class Meta:
model = OpenCv
fields = ['first_name','last_name','url','picture','bio','domain','specialisation','degree','year_last_degree','lyceum','references']
and the view:
def save_opencv(request):
if request.method == 'POST':
form = OpencvForm(request.POST, request.FILES)
# if 'picture' in request.FILES:
file = request.FILES['picture']
filename = file['filename']
fd = open('%s/%s' % (MEDIA_ROOT, filename), 'wb')
fd.write(file['content'])
fd.close()
if form.is_valid():
new_obj = form.save(commit=False)
new_obj.picture = form.cleaned_data['picture']
new_obj.created_by = request.user
new_obj.save()
return HttpResponseRedirect('.')
else:
form = OpencvForm()
return render_to_response('opencv/opencv_form.html', {
'form': form,
},
context_instance=RequestContext(request))
but i don't seem to save the picture in my database... something is wrong, and i can't figure out what :(
You don't make it easy to help you - you give no description of what actually happens.
However my guess is that you haven't included enctype="multipart/form-data"
in your HTML form
element.
I would recommend reading the file upload documentation - you're doing a few things manually here that could be handled for you by Django.
try:
filename = file.name
!
http://docs.djangoproject.com/en/dev/topics/http/file-uploads/
I've found the solution:
def save_opencv(request):
if request.method == 'POST':
form = OpencvForm(request.POST, request.FILES)
if form.is_valid():
handle_uploaded_file(request.FILES['picture'])
new_obj = form.save(commit=False)
new_obj.created_by = request.user
new_obj.save()
return HttpResponseRedirect('.')
else:
form = OpencvForm()
return render_to_response('opencv/opencv_form.html', {
'form': form,
},
context_instance=RequestContext(request))
and the handle_uploaded_file:
def handle_uploaded_file(f):
destination = open('root', 'wb+')
for chunk in f.chunks():
destination.write(chunk)
destination.close()
Please review the indentation.
Also, in models.py
I have:
picture = models.ImageField(help_text=('Upload an image (max %s kilobytes)' %settings.MAX_PHOTO_UPLOAD_SIZE),upload_to='root',blank=True)
Please be careful that I am saving it to root, which means THE ROOT OF MY SITE , not anything related to the computer file organisation. Also, there is not big deal about the code, the deal is the path - I really didn't understand how to set it at first. Anyway, hope it helps you.
Your error is here:
filename = file['filename']
It should be:
filename = file.name
Change this:
fd.write(file['content'])
to
fd.write(file.read())
