def upload_file(request):
if request.method == 'POST':
form = UploadFileForm(request.POST, request.FILES)
if form.is_valid():
handle_uploaded_file(request.FILES['file'])
return HttpResponseRedirect('/success/url/')
else:
form = UploadFileForm()
return render_to_response('upload.html', {'form': form})

Is it necessary to do HttpResponseRedirect in the form.is_valid block? Can't I do render_to_response there. I tried doing it, it posts two request instead of one. Why does it do that?

Thanks,

This is the http request that Django is getting. I am trying to read it directly by doing request.FILE('file'). I don't know if I should ask this question here, but is there something wrong with the http request here?

We are trying to interface the C++ client and a Django server. Now I want to read a zip file from the http request sent by the client.
I tried
1. Reading directly through request.FILES[‘file’]. This gives an “Key ‘file’ not found in <MutiValueDict:{}>” error
2. When I check for request.FILES, the condition fails.
Now we are trying to figure out, if the request is incorrect or I need to somehow bind the request file to the request.FILES variable on the server.

Any ideas?

Thanks,

Hi All,

I have two models

class A(models.model):
Field1
Field2

class B(models.model):
a = models.ForeignKey(A)

I want to get all the entries in model B grouped by a. I was wondering if there is a way to do that in django.

Dear Herbert Poul ,

Thank you once again. It worked.

Hi Everybody,

I have a query regarding declaring foreign keys for models in Django.
I have two tables A and B. I was wondering if it is possible to have a foreign key of table B in table A and also have a foreign key of table A in table B.
I was trying to do so but it complains about the table that is declared afterwards.

For example

Class A (models.Model):
b = models.ForeignKey (B)

Class B (models.Model):
a = models.ForeignKey (A)

It gives me error that variable B is not defined. And if I declare Class B first it says variable A not defined.

Hello Herbert,

Thank you very much for your response. It helped a lot. That is exactly what my questions was.

How does Django handle multiple http request? Do we have to do it in Django code to spawn process?.
I was reading about Django integration with Apache and mod_python, do these handle request?
