problem handling upload file django
I'm trying to do a feature that would allow the user to upload a file. That file would have information to insert into the database, that's why in the function I'm saving data. Not sure if it's the best option.
What I've done so far:
forms.py:
class UploadFileForm(forms.Form):
file = forms.FileField()
views:
def last_step(request, word):
if request.method == 'POST':
form = UploadFileForm(request.POST, request.FILES)
if form.is_valid():
msg = handle_uploaded_file(word, request.FILES['file'])
return render_to_response('final_insert.html', {'msg': msg})
else:
form = UploadFileForm()
return render_to_response('upload.html',
{
'word': word,
'form': form })
template:
<form enctype="multipart/form-data" action="{% url upload_done 'clinical' %}" method="post">
<div>
{% for field in form %}
{{ field }}
{% endfor %}
<input type="submit" value="Save" />
</div>
</form>
function:
def handle_uploaded_file(word, f):
msg = "first stop"
data = []
for chunk in f.chunks():
data.append(chunk)
msg = "after chunk"
开发者_如何学编程 if word == 'clinical':
pat = Patient.objects.values_list('patient', flat=True)
for i in data:
if i[0] not in pat:
b2 = Patient(patient=i[0])
b2.save()
msg = "number was inserted"
else:
msg = "something"
return msg
The problem is when I hit "save" in the template, it redirects well to another template, but I don't see any message, like I suppose to see (final_insert.html shows {{ msg }})
Can someone help me understand what I'm doing wrong?
Any help is welcome! Thanks for your help!I was able to understand my mistake.
sorry guys for my silly mistake
so this is the form:
<form enctype="multipart/form-data" action="{% url upload_done 'clinical' %}" method="post">
<div>
{% for field in form %}
{{ field }}
{% endfor %}
<input type="submit" value="Save" />
</div>
</form>
urls:
url(r'^insert/file/(?P<word>clinical)/upload/$', last_step, name="upload"),
url(r'^insert/file/(?P<word>clinical)/upload/result/$', final, name='upload_done'),
so the view last_step corresponds to the url "upload" and not "upload_done"
I wrote into the form action={% url upload_done 'clinical' %}, so when I hit save it will redirect me automatically to the other template. Without running the code!!
So I changed the form to:
<form enctype="multipart/form-data" action="{% url upload 'clinical' %}" method="post">
<div>
{% for field in form %}
{{ field.label_tag }}
{{ field }}
{% endfor %}
<input type="submit" value="Guardar" />
</div>
</form>
and now it works..
sorry guys, I thought I needed to redirect to the other page but when he redirects he doesn't run the code..
