Anything beyond a question mark is a parameter and is better handled inside your view. So, your urls.py would look like this: (r"^wap/di/sub", hellow) And your view would contain the following code: def hellow(request): word = request.GET['word'] return HttpResponse(word) But you should need two things: - the code does not contain any error checking (i.e. what happens if "word" is not provided in the URL - There is a security issue. Displaying anything that user provides on the output page *without checking it first* is insecure and can lead to various security-related issues I'll leave the JavaScript bit to your excercise as I don't really understand what you're trying to achieve with that.

design problem..how to store web page's data for later comparison
hi I am trying to write an application that checks a web page today and again checks it after somedays and compares them.For this purpose I need to store the page data on these 2 occassions in my program . How can I do this?I can get the page data of current moment as a string using urllib.urlopen and store it in a variable, say current_page_data.But ,how do I store yesterday's data so that I can compare the two?Do I need to store it as a field in database?(I am not very familiar with database programming..I am using postgres for web app development with django.So I don't know if storing such a large string like that is possible). I considered writing the data to a file..but suppose a lot of users want to do the comparison of 2 versions of many pages..?I would be creating so many files =usercount * number_of_url_by_each_user .If the time duration between 2 comparisons was some seconds/minutes then I can just use 2 local variables andmay not need persistence.But ,to compare data of yesterday and today I may need some such mechanism.. I guess this may be a common problem and there may some solution for this. Can someone comment/suggest how this can be done? thanks jim -- You received this message because you are subscribed to the Google Groups "Django users" group.

Yes, it's definitely possible. DBs support very large text fields nowadays, I wouldn't worry about it. Postgres's text field type is only limited by the 1GB value-size limit general to all Postgres DB fields. > I considered writing the data to a file..but suppose a lot of users > want to do the comparison of 2 versions of many pages..?I would be > creating so many files =usercount * number_of_url_by_each_user .If > the time duration between 2 comparisons was some seconds/minutes then > I can just use 2 local variables andmay not need persistence.But ,to > compare data of yesterday and today I may need some such mechanism.. You will definitely want persistence, but if you do choose to go the files route I wouldn't worry about the storage space. If you have enough users for that to be a problem you should be able to afford the space, cloud-based storage like Amazon's S3 is cheap and easy. If you're really resource constrained you can always just compress\decompress the files, text compresses very well. It'll add some processing overhead for sure, but there's no magic bullet that's not going to cost you some form of resource or another. Just limit the number of versions that can be kept and remove the old-ones on a rolling basis...

Found this: http://stackoverflow.com/questions/283724/big-integer-field-in-django-models which implies it should "just work" from version 1.2 onwards. Be aware that Django's sync method wil create the PK field with a default of int(11), not bigint, so you'll need to change that in the database itself. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: moving from Postgres to MySQL
One way would be to use the dumpdata command to export everything, change your settings to point to the new database, then loaddata to restore. There may be a better way, but this way allows you to dump to a database-agnostic backup so it seems like it would suit your needs.

Smaller Than in Django database API

How does one filer objects by "smaller than" criteria in the data access
API? For example, in the following line:
MySite.objects.filter(*rank < 11*, display_on_site = 1).order_by('rank') -
how would one handle the highlighted criterion?

Note also that, AFAIK, multiple where criteria are accomplished by chaining
filters rather than providing them as a list to one filter call.
But I am new to Django myself, so if anyone corrects this advice - follow their

Unicode, utf8, mysql
Hi all, I'm the main maintainer of a website called l'Agenda Du libre du Québec. On this website, people can submit events about free/open software in their local community. Yesterday, somebody tried to submit a new event, but the in description of the event, there was a strange character: "→". Django can deal with this unicode character, and MySQL, correctly configured, should be able to also. But it's not the case. MySQL just refuse to save it ! Saying that there's an invalid character inside this field. What can do ? I don't want to filtering it manually and just wait for the next bug for the next incompatible character with MySQL ! -- Mathieu Leduc-Hamel -- You received this message because you are subscribed to the Google Groups "Django users" group.

That's not quite right, both are suitable (and _can_ have different
meanings, although not in this case).
If you assume models like so:
class Item:
name = CharField
type = ManyToManyField('Type')
class Type:
name = CharField
enabled = BooleanField
displayable = BooleanField
then these two lines are different query sets:
Item.objects.filter(type__enabled=True, type__displayable=True)
Item.objects.filter(type__enabled=True).filter(type__displayable=True)
The former selects Items with one or more associated Type instances
that are both enabled and displayable. The latter selects Items that
have one or more associated Type instances that are enabled and
displayable, but not necessarily the on the same Type object.
When the filter is not over a m2m field though, the two forms are
largely equivalent.

Re: Smaller Than in Django database API
@Jonathan, thanks. That does the trick.
@Tom, thanks for bringing the subtle, yet important, difference between the
two forms of that expression to my attention.

POST the form several times
hi all, need your help to understand whether the following can be done with django (and if can - then how). I have items array, which contains details of files. I need to upload them to the server (with POST request), but it supports uploading of 5 files at once only, filenames to be passed in fields file1, file2 etc. My items array can contain much more elements (i.e. files) then 5. Is there any way to take 5 first files from the array, send it, wait for result, then take next 5 files, send them etc.? -- You received this message because you are subscribed to the Google Groups "Django users" group.

Legacy URLs redirect
I'm sure this is simple and I'm just not constructing the URL
properly. Basically, it used to be a drupal site, with the cruddy old
Drupal every url is a querystring setup. What I want is pretty
simple... all of those old URLs resolve to the home page and send a
301 to the spider.
I tried:
(r'^?q=taxonomy/term/[0-9]+$', redirect_to, {'url': '/', 'permanent':
True}),
And failed most spectacularly. Do I need to be escaping something, or
what am I missing?

Custom validation in model formset
Hi all,
I'm trying to do some custom validation on a model formset, but I'm
not having good luck. Thank you in advance for your suggestions ...
In my views, I have:
class BaseCandFormSet(BaseModelFormSet):
def clean(self):
super(BaseCandFormSet, self).clean()
for form in self.forms:
x = form['x_field']
y = form['y_field']
if y < x:
raise forms.ValidationError('Y cannot be less than x.')
I get the following error:
Exception Value: 'list' object has no attribute 'ValidationError'

On my mobile so can't check but I suspect forms is a list of form objects, try
form.validation error instead...
Good luck!

When you install Django with setuptools (i.e. using setup.py) then you should find that django-admin is placed where it can be found. The simplest way around this is to make a symbolic link from one of the directories on your path to the django-admin.py file. regards Steve -- DjangoCon US 2010 September 7-9 http://djangocon.us/ -- You received this message because you are subscribed to the Google Groups "Django users" group.

Changing forms to form brings a new error:

Below is the view that is using the BaseCandFormSet code that I included in
the original message. Maybe something is wrong in it? Thanks in advance for
your suggestions. I've spent a few days using the documentation and trying
to get this to work. I really appreciate the help. ...

Re: moving from Postgres to MySQL
I am in the process of migrating a postgresql database to oracle which has a lot of data. I tried to use the dumpdata command but because of the amount of data I had to scrap the plan.

What you're missing is that elements after the ? are *not* part of the
URL - they are part of the querystring. These are passed through into
the view and can be accessed via request.GET.
In any case, for a blanket redirect like that, you would be better off
doing it directly via Apache (or whatever your webserver software is),
rather than invoking Django each time.
