No module named django after upgrade to os x Lion
Hello, I'm new to both Python and Django. A few months ago, I installed Django on my mac (running Snow Leopard). I took me quite some time, but I got it running. After that I didn't get around to doing anything with it. A few weeks ago, I upgraded my mac to run Lion and now, when I type import django in the python interpreter, it says No module named django. I found someone who had had a similar problem, and I'm guessing it could be connected to the fact that Lion comes with Python 2.7.1? My Django version is 1.2.5. Again, I know almost nothing about Python, so I could be way off base. Any ideas how I can solve this, or find out what the problem is? /Angelika -- You received this message because you are subscribed to the Google Groups "Django users" group.

Optimisation Models
Optimisation Model Hi everyone, I'm working on the optimization of the model of my app. The goal is to limit the request to the database. In this webapp every user can follow users (like twitter), and when someone you follow publish an article, each followers reveive a mail. I'm wondering what is the best choice of models between this 2 example : class UserProfile(models.Model): ... followers = ManyToMany(self) Or class Followers(models.Model): poster = OneToOne(UserProfile) followers = ManyToMany(UserProfile) First i was thinking about the example1, but I'm afraid that of each time I will do a UserProfile.objects.get DJANGO join UserProfile table to itself in order to retrieve all the followers.

Accuracy of GeoIP?
Does anyone have experience with the accuracy of GeoIP? I'm getting locations that are wildly off...

Re: New member question about developing in Ubuntu Server
Hello Ethan, Welcome to Django, the web framework for people with deadlines and great taste! Django absolutely does not require access to the builtin (or contrib, as we call it on djangoland) admin app in order for you to configure models. A model is a representation of a way to store data, which in regular Django setups is a description of a database table. In order to define said table, one needs only a little knowledge and a text editor so that models.py can be edited, which is where model definitions live. The admin is simply a generic web application that ships with django in order to help you get some actual data in those tables in little time. It is not, contrary to what you may have been led to believe, a prerequisite to working with Django. In fact, the further you go from basic CRUD functionality, the harder it gets to make the admin app fit to your requirements. To sum it all up, a model is defined in models.py, and the admin is one of many ways to add rows to your database tables. Having said that, I must recommend that you develop locally at first so that you can leverage the features provided by the dev server, namely auto reloading on code changes and handy debugging tools. While you're at it, look up virtualenv. You'll thank me eventually! Good luck and happy coding!

Re: Long usernames in auth_user?
Then again, you can't assume an email to not have spaces as "John Doe"@example.com is a valid email per the RFC. If you *really* need flexibility, have a UserProfile model with a OneToOne relation to User and your imagination will be the only limit.

Re: Long usernames in auth_user?
Check out userena as well. But a custom authentication back-end was the approach I originally took. And to answer your question, yes -- your chances of finding people w/ email addresses longer than 75 chars are less than finding people w/ 30 chars -- but still a limitation none-the-less as there is no limitation on how long an email address can be.

Now - of course the problem can easily crop up again by just increasing length; but if the username length and the email length at least default to the same value (the email field has length 75) the failure will at least be simultaneous - and the usage pattern I describe will work until the 75 characters e-mail limit is reached.

Re: Long usernames in auth_user?
This is a known limitation and it's something that people _want_ to get fixed (but just merely increasing the length isn't helpful, because soon someone comes along with the new length + 1 and the same problem occurs). The issue is that the django.contrib.auth User model while providing a minimum (sort of) set of fields for a user, doesn't let you enhance it's internals very well. I think the core dev's are mostly waiting for someone to come up with a good solution to this problem. Now to answer your other question. There are 2 general ways of handling this, and neither one is perfect. One is to do as you did and modify the db to allow longer usernames, also being careful to modify anyplace that validates that the length is 30 so that it works across the sites. The other method is to create your own auth handler (Pinax comes with one) that let's you authenticate against the email field on auth.User. Then in your signup process you save their email address to this field, and generate the username (I'm fond of UUID's for this). The final (optional) piece of this puzzle is to monkey patch User.__unicode__ to return self.email instead of self.username.

Long usernames in auth_user?
Hello, I have been using a (in general quite popular I think ...) convention where the e-mail address has been used as username. I have solved this by asking the user for an e-mail address and a password, and then used the supplied e-mail address both as username and e-mail address when instantiating a User object. This has worked fine up until now. Now suddenly someone came along with an e-mail address which was longer than the 30 characters limit imposed on the username; and things went to pieces. I have Googled this topic but did not find any clear cut simple solution, altough I am definitely not the first one to stumble over this problem. So two questions: 1) I modified the (development) database directly increasing the field size from 30 to 75; and that seemed to work nicely; but I am not very comfortable about the solution. What do you say? 2) Any chance of changing this in a future release? Joakim -- You received this message because you are subscribed to the Google Groups "Django users" group.

Help Required with Image Upload
Hello All,
Am pretty new to Django. I am trying to create a form which will upload an
image and then enable the user to crop visually (using JCrop plugin). Am
not completely sure on how to implement this in Django. I am thinking of
first saving the uploaded image into the disk as a jpeg file and then load
and display the image as an overlay where the user can crop the image. I am
able to create a form with the image field and then am passing over
request.FILE to a function called handle_uploaded_image. Following is
my handle_uploaded_image function
def handle_uploaded_image(self, image):
"""
This function is to handle uploaded image file
"""
imageFile = Image.open(StringIO.StringIO(image.read()))
fileName = hashlib.md5(imageFile.getvalue()).hexdigest()+'.jpg'
Now i am kind of confused on how to convert the uploaded image into jpg
using PIL, and then saving into the disk. I had defined a field in my model
to save the image file name which is as follows:
class UserProfile(models.Model):
avatar = models.ImageField(_('Avatar'),upload_to=settings.IMAGE_UPLOAD_PATH,
null=True)
I did this based on the django documentation, but it tells something about
binding the form which am not able to correctly understand. Why do we need
to bind a form with image field. Also whats the use of giving upload_to in
model image field? Thanks in advance for any help.
Regards,
Swaroop Shankar V

Re: Field.Choices in Template
Hey Guys,
I hate to bother you again. But -- is there a way to get the currently
selected data from this set? For example, a user hits the page and all
choices are displayed fine. But, they pick some choices. They haven't
finished editing the form or maybe they made a mistake, anyways they land in
the form_invalid land. I'd like to be able to use this same technique to
make sure I properly display what the user has selected thus-far.
Thanks!

Happy to bite on that one and am chuckling away at that. Databases are the engines, and yes, you do find engine specialists in car forums because cars are the raison d'etre.

Weird situation about static file

In my opinion as a starter too, I don't think you need a model if you are not using a database. Others could have their opinions.

NEWBIE: using django without a model.
Hi, I am trying to create a simple query page using django and pig!. I would not be needing a database, so I'm not sure if a model is involved.

combining media of more than one form or needed for the rest of the page
Hi, I wonder how you all combine media of forms or other stuff in your page. I read here one solution could be writing a template tag or filter to combine the media objects by simply using the + operator. So how are you constructing your pages, if you are using templates? So far I used forms for input, but all other UI elements where pasted into the HTML template in raw html e.g. an ajax table. But a page does not only consist of forms - there could be: - toolbar - status bar - (ajax-) tables - context-menus - tab controls - javascript functions - and what ever you like... is there a raw concept on how to use more elements then forms or maybe even more than a concept, that I did not recognize? How are you solving this? regards Henrik -- You received this message because you are subscribed to the Google Groups "Django users" group.

My current setup has a multi data centre, multi master replication, with a couple of read slaves in each data centre, but the only thing Django has to do with it is decide which database server to use, everything else is taken care of by the database software (MySQL).

Re: Custom upload handler in generic view
AFAIK, it's also doable with apache, with little modification from the code I provided. I just haven't had the chance to investigate the possibilities yet. Before I say anything else, I must admit I completely forgot to provide a very important file for the upload progress thingy: the javascript file [1] which fetches information from the server! As for your question, I honestly can't say I'm an authority on the matter, but from my understanding, the custom upload handler will do the talking between django and nginx. The way upload handlers work is pretty much beyond my knowledge, so for now I'm just going to accept the fact that it works :P Cheers, AT [1] https://github.com/drogus/jquery-upload-progress/blob/master/jquery.uploadProgress.js On Wed, Oct 26, 2011 at 10:31 AM, hbf wrote: > Thanks for your reply and the detailed information. > > Your solution looks great, and I guess that using a web server-based > solution (in contrast to a Django-based one) is much more efficient. > What I do not understand in your setup is why, if you have > HttpUploadProgressModule installed, you do need a custom upload > handler and AJAX view?

Most databases support replication, MySQL replication is simple, PostgreSQL not so much, but that is way off topic for a django list. There are also tools you can use to compare two databases. Percona toolkit has some excellent checksumming tools for checksumming MySQL tables - to ensure that the same data is on both sides - and I'm sure someone who knows what the equivalent is for Postgres will be along shortly.

Multiple database Router
I need to synchronize multiple databases, i have readed the https://docs.djangoproject.com/en/1.3/topics/db/multi-db/ where they explain how to make this. but i dont understand what do they refer with 'myapp' and 'other', are this tables from the database? I dont understand what do they mean. I just want to compare and synchronize two databases db1 and db2, that have the same tables but different data. can anyone suggest what can i do Thanks -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Custom upload handler in generic view
Thanks for your reply and the detailed information.
Your solution looks great, and I guess that using a web server-based
solution (in contrast to a Django-based one) is much more efficient.
What I do not understand in your setup is why, if you have
HttpUploadProgressModule installed, you do need a custom upload
handler and AJAX view? IIUC HttpUploadProgressModule is providing this
for free, isn't it?
Unfortunately, my hoster is not using nginx but Apache. Maybe there is
a Django-compatible module for it out there;
https://github.com/drogus/apache-upload-progress-module/ seems to be
an option but I haven't tried it yet.
Best,
Kaspar

Re: Custom upload handler in generic view
Are you using nginx by any chance? I use nginx and my setup is as follows:
A upload.py with the custom handler and a view to yield progress result as
json [1], a template with some javascript [2] to fetch the json-formatted
progress result, some lines in nginx.conf [3] to tell it to keep track of
uploads (nginx must be compiled with HttpUploadProgressModule [4]) and a bit
of patience to get it up and running.
I have compiled nginx for windows with that additional module. The
instructions are pretty much gone at this point, but I can zip the binaries
and send it your way should you need them.
You will also notice that I use a /projects/mysite/mysite layout for my
django projects, which is consistent with the new layout in 1.4/trunk [5].
I almost forgot! I'm also using a custom JSONMixin which calls get_data() on
ajax requests in any view that implements it and returns self.data (to be
set by self.get_data) as json [6].
Best of luck!

Custom upload handler in generic view
Dear all,
In order to provide progress feedback of file uploads I needed to
install an upload handler for a specific view. This is documented for
"classical" views at
https://docs.djangoproject.com/en/dev/topics/http/file-uploads/#modifying-upload-handlers-on-the-fly
For generic views, however, I could not find any instructions and I
came up with the following, which I would like to share:
# BEGIN OF CLASS
from django.utils import importlib
from django.core.exceptions import ImproperlyConfigured
from django.views.decorators.csrf import csrf_protect
class UploadHandlerMixin(object):
'''
A mixin for Django generic views that installs a custom upload
handler in front of
the current chain of upload handlers.
You specify the handler to install by overriding the
'upload_handler' attribute of
the class, specifying the module and class name in the form
'path.to.module.class':
class MyView(UploadHandlerMixin, View):
upload_handler = 'path.to.module.MyUploadHandler'
If you do not override 'upload_handler', no additional upload
handler will be
installed.
If the CsrfViewMiddleware is installed (which is the default)
then you must use
your view as follows in your urls.py:
from django.views.decorators.csrf import csrf_exempt
url(r'^.../$', csrf_exempt(MyView.as_view()), ...),
Internally, the UploadHandlerMixin mixin will install the
upload handler and then
perform the CSRF check. (This is necessary because the CSRF
check inspects
request.POST, and afterwards upload handlers cannot be
changed, see documentation
link given below.)
The handler is installed as described in the Django
documentation "Modifying upload handlers
on the fly", see
https://docs.djangoproject.com/en/dev/topics/http/file-uploads/#modifying-upload-handlers-on-the-fly
'''
upload_handler = None
def dispatch(self, request, *args, **kwargs):
if not self.upload_handler is None:
request.upload_handlers.insert(0,
UploadHandlerMixin._instantiate_upload_handler(self.upload_handler,
request))
return _uploadhandler_dispatch(request, self, *args, **kwargs)
@staticmethod
def _instantiate_upload_handler(path, *args, **kwargs):
i = path.rfind('.')
module, attr = path[:i], path[i+1:]
try:
mod = importlib.import_module(module)
except ImportError, e:
raise ImproperlyConfigured('Error importing upload handler
module %s: "%s"' % (module, e))
except ValueError, e:
raise ImproperlyConfigured('Error importing upload handler
module. Is FILE_UPLOAD_HANDLERS a correctly defined list or tuple?')
try:
cls = getattr(mod, attr)
except AttributeError:
raise ImproperlyConfigured('Module "%s" does not define a
"%s" upload handler backend' % (module, attr))
return cls(*args, **kwargs)
@csrf_protect
def _uploadhandler_dispatch(request, view, *args, **kwargs):
return super(UploadHandlerMixin, view).dispatch(request, *args,
**kwargs)
# END OF CLASS
Not being a Django expert, I wanted to ask whether this is okay
security-wise? Any other feedback is of course welcome.
Best,
Kaspar

queryset extension with field from different model
Hi, this is just a question to help me understand queryset usage a little better. If I had two models, unrelated via foreignkey etc, but which shared a common field, e.g. class modelOne(models.Model): a = b = c = class modelTwo(models.Model): c = d = e = how can I create a queryset pulling in features of both. That is, if I had myqueryset = modelOne.objects.all() how can I append the d value from modelTwo (having worked out the matching c values) to myqueryset? For example, I'm assuming this is not the way I should be doing this: myqueryset = modelOne.objects.all() for item in myqueryset: dvalue = item.dvalue = dvalue Any pointers for how I should be doing this? (noting that I have the use case for ending up with a single queryset) Many Thanks, G -- You received this message because you are subscribed to the Google Groups "Django users" group.

You're on the right track with inlineformset, but you still need to render
the parent form separately - the formset is only the related items, not the
parent. So just pass `authorForm` to the context and display it as normal
(with `{{ authorForm.as_p }}` or by iterating through the fields).

Regression in blocktrans tag parsing between 1.2 and 1.3
Hi all
Django 1.3's blocktrans tag is documented as still supporting 1.2's
more verbose syntax. However, if you attempt a plural translation, it
barfs. More importantly, it rejects a format that 1.2 accepts, and
accepts a format that 1.2 rejects.
This format is rejected by 1.2 and accepted by 1.3:
tmpl2 = """
{% load i18n %}
{% blocktrans with items as stuff and count items|length|add:"-3" as
more_count %}
{{ more_count }} more
{% plural %}
{{ more_count }} more
{% endblocktrans %}
"""
This format is accepted by 1.2 and rejected by 1.3:
tmpl3 = """
{% load i18n %}
{% blocktrans count items|length|add:"-3" as more_count and items as stuff %}
{{ more_count }} more
{% plural %}
{{ more_count }} more
{% endblocktrans %}
"""
The 1.3 documentation states that "The previous more verbose format is
still supported", without going into details of what that format is.
This probably requires either a fix to be more 1.2 compatible, or a
documentation note in 1.3 noting the differences in formats that it
will parse and an update to the 1.3 backwards incompatibilities
noting this difference.
Cheers
Tom
