Thanks Caz, this makes sense and it's confirmed by the fact that
uploading a non binary file didn't produce any beep even having the
print statement.

I've removed the print statement now and everything is fine ;-)

Re: Multiple file upload crashes dev server

[Caz]

Hi Lorenzo

I suspect its not that you are uploading 2 files, but which files u
upload.

The line
print "%s %s %s %s" % (k, new_data[k]["filename"],new_data[k]["content-
type"], new_data[k]["content"])
Will print the actual content of the file you are uploading.

Now if thats an image or binary file the char \x07 will appear in it.
Which is system beep.(Printing char \x07 will make windows beep, Dell
does not play nicely with system beep, no way to mute it, I know, I
have one.)

So with many \x07 chars in the content you system is going to look
like its hanging beeping like crazy until its beeped its way through
the files you are uploading.

Re: Multiple file upload crashes dev server

[Benjamin Slavin]

You might want to throw some logging into your application (Python's
logging module). [0]  If you use logging, you'll be able to get a
better handle on where the problem is actually happening.

I've heard of the dev server crashing ungracefully when it encounters
an error, but have never seen it myself.  The reports I've heard all
end up being programmer error, not problems with Django.  Also, I've
never heard of it taking down the whole machine.

I know this is going to sound like a cop-out, but it really sounds
like a hardware problem. There is no reason why a python script of ANY
kind would cause a hardware lockup as you are describing. It sounds
more like a memory fault. If it happens with more than one machine I
would be extremely impressed.

Hi Malcolm,

the problem is very difficult to debug because the script above, when
executed, brings down the dev server _and_ the OS with it! Everything
comes to a stall and requires a hard reboot.

This happens _all_ the time and i've now verified the same problem on
my laptop that runs WinXp SP2 with Py2.4.

The PC literally starts beeping like mad (it's a hardware beep that
you can hear even if the speakers are off).

Thanks,
Lorenzo

I have no idea what's going on, but "crashes the dev server" needs more
information. Crashes with what error message? At which point in the
process? Every time or sporadically? If you can provide some more
descriptive symptoms, it might trigger a thought for somebody.

Multiple file upload crashes dev server

[[EMAIL PROTECTED]]

Hi everybody,

the following script running on the dev server with Py2.4/Win2k3
(tested on both IE7 and FF2) crashes the dev server. The funny thing
is that the files get actually written to the filesystem and CPU usage
is normal.

What i'm trying to do is allow uploading of an undeterminate number N
of files, just as GMail does.

The javascript part uses jquery.

Thanks,
Lorenzo

You seem to have missed my point - you don't use the manipulator for Image - you use the manipulator for Description. You want the manipulator that has Image objects  edited inline. If you don't have a Description-like object, you will need to create one. Call it an ImageCollection, and attach to whatever object needs collections of images.

AddManipulator(), a method from each Model. The Image model would haveto have multiple ImageField fields so that django can save them all,but anyways that would create *a single Image Object*
 Hence, a single ImageCollection object, tied to a single FormWrapper and manipulator.Yours,Russ Magee %-)

Re: Multiple File Upload???

[cerealito]

Ok, as a reminder, here is the Image model I am using:

class Image(models.Model):
altText = models.CharField(maxlength = 128, null = True, blank =
True)
picture = models.ImageField(upload_to='img/%Y/%m')

The problem is that i want to create multiple objects of this type from
a single upload form (and thus uploading multiple files)

Well No, not exactly, and that's why started this thread. If I call
those methods, only one file (the last one in the form) will get
uploded and its data saved to the database. The rest of the files in
the post request seem to be lost.

The problem relies on the fact that FormWrapper seems to be associated
to one manipulator, and that the manipulator is in turn created by
AddManipulator(), a method from each Model. The Image model would have
to have multiple ImageField fields so that django can save them all,
but anyways that would create *a single Image Object*

So Apparently, if i want to upload multiple files and create with them
an equal number of Image objects, it seems to me that i have to do it
"one by one" (an upload for each post request).

I will try by creating multiple FormWrappers, but I think that will
imply knowing how many files will be uploaded, which is not exactly
cool.

Anyways, thanks a lot for your replies. I will keep trying and let you
know what i found.

As far as I can see, all that remains is to pass your request into the Description Manipulator to get_validation_errors, do_html2python, and save. This process should handle writing the files to disk.
BTW: Re _javascript_ - I was only suggesting _javascript_ that if you want a really fancy Gmail-esque UI. _javascript_ won't help you save multiple files, it will only make the interface for specifying them a little more Web

Is that what you are after?By this model, every Image belongs to a single Description (so a description can have multiple images). Image is edited inline, so you get a list of images to add. It isn't quite as dynamic as GMail (you need some AJAX magic for that), but it's the functional part of the solution.

Re: Multiple File Upload???

[cerealito]

Ok, the problem then is, that my model has just a single entity called
picture.
What I'm trying to do is asociate multiple image files to multiple
`descriptions'.
I'm doing this by a intermedaite table:

#Images to be used in descriptions
class Image(models.Model):
altText = models.CharField(maxlength = 128, null = True, blank =
True)
picture = models.ImageField(upload_to='img/%Y/%m')
...

# Replaces the Many-to-Many Relationship
class ImageInDescription(models.Model):
description = models.ForeignKey(Description,
edit_inline=models.TABULAR, num_in_admin=3)
image = models.ForeignKey(Image, core = True)
...

#Descriptions
class Description(models.Model):
lang = models.ForeignKey(Lang)
description = models.TextField(null = True, blank = True)
...

That's it. So as you can see in the first class, `Image' is itself an
element to be uploaded. I guess I could add more ImageFields to the
model but that would't make sense, would it?

Isn't there a way to upload as many files as i want to (much like gmail
handles attatchments)
and then associating them to the descriptions?

Multiple File Upload???

[cerealito]

Hi everyone,

I am trying to upload multiple image files in one of my projects.
Single-File upload works fine, but how do I Get to upload many files in
the same form?

I have many of these in the templates:
{{ form.picture }} {{ form.picture_file }}

Then on my views i have:
for file in request.FILES.getlist('picture_file'):
print( file )# i can see the dictonary-like
objects in the server output...

But my question is... How do I "save" them?

imageManipulator.do_html2python(new_data)
imageManipulator.save(new_data)

Wouldn't work...

Can anybody point me into the right direction? I've been browsing
through the docs and I couldn't find any useful info. I'm sure someone
has already passed through this. I would really appreciate any clue.

Thanks in advance.

Django Fan and Newbie #6134
