Re: how to make radio buttion selected as form is loaded
Reporting back on this one. I solved the problem, but perhaps there's
a more elegant way of writing this.
1) Discovered that I was not in fact comparing like data types, so {%
ifequal %} was bound to fail. (Pardon my newb-ness)
2) Once I fixed that problem, I ended up putting six ifequals together
in the loop, so that the radio button would be checked if any one of
the six possible selections in the "selections" list was equal:

My understanding from what I've read is that most of the heavy lifting for image handling is done by PIL (Python Imaging Library) < http://www.pythonware.com/products/pil/ >. I've been getting into using virtualenv and as part of that I've been doing some PIL easy_installs. One PIL install was built with the jpeg library and when I tried uploading a jpeg image file, all went well. Another PIL was built without the jpeg library and when I tried to upload a jpeg image file, Django complained that the image wasn't in a recognized format. So, I assume Django is passing the file to PIL and asking if the file is in a format that PIL can deal with and is in a valid format. The PIL documentation may be able to clarify how it validates images. Toodle-l creecode -- You received this message because you are subscribed to the Google Groups "Django users" group.

You can't. You have specified a model that has a dependency on itself.
This is a situation where you can't use natural keys.

What validation tests are applied to ImageField?
The documentation states about the ImageField "Like FileField, but validates that the uploaded object is a valid image. Has two extra optional arguments:" http://docs.djangoproject.com/en/dev/ref/models/fields/#imagefield I went cruising the source to try and work out what tests are implemented to define "a valid image" but didn't get much satisfaction. There seemed to be a fair bit of talk about dimensions but nothing about much else. I was thinking/hoping to find something which inspected the binary stream to ensure the .jpg/.gif/.png/.bmp fit its applicable formats. Question is "What is the definition of a 'valid image'" in this context?" and, optionally, where is the source code for that? t.i.a. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Using urlencode with the url tag
I'm trying to generate a link where the URL of the current page gets
passed in the querystring of the link. Like so: .
I would have thought that I could do this relatively easily with
template tags, so I've tried this:
<% url arg1, arg2 as the_url %>
http://www.example.com?variable={{ the_url|urlencode }}">
However, for whatever reason, the urlencode filter isn't applied when
the_url renders. Is there a way to do this directly in the template,
or do I have to generate the encoded URL in the view and pass it to
the template?

Co-incidentally I was asking a very similar question, I couldn't see any way to use the model information in a formset. In the first instance I'm just passing in the data, I assume it isn't possible to use that as variables elsewhere? Also, in the view, is it possible to reference a model associated with each form in the formset? This is a simplified version of the view: http://dpaste.com/172317/ That's aimed at taking in multiple events and multiple members, which is fine except that I can't see how to reference the members when: - In the form (template). - Iterating over the form information. E.g. this doesn't work: for entry_form in entry_formset.cleaned_data: this_member = members[entry_form] Any pointers appreciated, I can't find a similar instance in the docs.

Re: Handling upload, adding M2M relation before saving object in admin form
Thanks for your answer, but I do need a ManyToManyField().
In case anyone is curious about the answer, I solved my problem by
overriding my custom admin form's save method. In save(), I checked for the
existence of the file field in self.files; passed self.files to a document
form, which populates a new Document object, returns that (using
commit=False), save it manually so we can get the new primary key, then add
that primary key to Publication's form's documents field
(self.cleaned_data['documents']); then save the whole thing to the database
using super(). Turned out this was lot simpler than I originally thought it
would be, fortunately.
admin.py:
class PublicationAdmin (models.AdminForm):
form = CustomForm
forms.py:
class DocumentForm (models.ModelForm):
class Meta:
model = Document
class CustomForm (models.ModelForm):
class Meta:
model = Publication
# custom documentwidget is a hiden select box of document ids
# with some jquery, and a file upload field
documents = forms.MultipleChoiceField(widget=CustomDocumentWidget)
def save(self, *args, **kwargs):
if 'file' in self.files:
docform = DocumentForm(files=self.files)
document = docform.save(commit=False)
document.save()
if document.pk: # add m2m relation with new document
self.cleaned_data['documents'].append(document.pk)
super(CustomForm, self).save(*args, **kwargs)
return self.instance

Re: File validation process
Thanks for the reply hcarvalhoalves. I can see bypassing the file name extensions as you have mentioned, they don't guarantee the file type anyway. That said, I would like to be able to use some other means than mimetypes as I need to make sure that the files are of a specific type (e.g. not just a video file but one with a specific file header.) As for the interruption of the upload itself however, that is pretty crucial as the files would be around 1 GB each and I wouldn't want a user to have to wait for it to complete only to find out that it was of the wrong file type.

Re: form.save_m2m() and exclude field
hi,
sorry. Here's the copy of the traceback.
It's actually a warning, not an error.
I'm using form.save_m2m() because my model includes another m2m field
(I simplified the code for readability), and I'm using
form.save(commit=False) because I don't set the city field using the
city value from request.POST but from further processing of the data.
It still seems to me that save_m2m() tries to save the excluded tag
field.
Thanks for your help.

Firstly, it is no use just giving the name of the error. Errors come
with tracebacks, for good reason: they allow us to see exactly where
the error is occurring, and the context.
Anyway, in your case, there doesn't seem to be any need to use
save_m2m. The documentation states:
"Calling save_m2m() is only required if you use save(commit=False)"
In your case, you've already saved the form to get the new_restaurant
instance, and you're adding tags to that instance with no problem. The
last two calls, to new_restaurant.save() and form.save_m2m(), are
unnecessary.

form.save_m2m() and exclude field
hi,
in a ModelForm I replace a field by excluding it and adding a new one
with the same name, as shown below in AddRestaurantForm. When saving
the form with the code shown below, I get an error in form save_m2m()
(Truncated incorrect DOUBLE value), which seems to be due to the
function to attempt to save the tag field, while it is excluded.
Is the save_m2m() function supposed to save excluded fields?
Is there anything wrong in my code?
Thanks

Trouble installing satchmo
I'm trying to get satchmo up and running from the instructions at http://bitbucket.org/chris1610/satchmo/downloads/Satchmo.pdf , and when I get to 2.1.3 (installing PIL manually as a workaround), there is no /bin/clonesatchmo.py. After digging around, I move the scripts from the install directory to under /usr/local, and create a symlink to clonesatchmo.py. But it can't find things; my guess is that it's looking in my PYTHONPATH and the same install issues that left no /bin/clonesatchmo.py has left no Python files installed to the default PYTHONPATH. I get: $ python /bin/clonesatchmo.py Creating the Satchmo Application Traceback (most recent call last): File "/bin/clonesatchmo.py", line 108, in create_satchmo_site(opts.site_name) File "/bin/clonesatchmo.py", line 47, in create_satchmo_site import satchmo_skeleton ImportError: No module named satchmo_skeleton Do people have suggestions, including going to a Satchmo-specific list if this list is not intended to discuss Django add-ons like Satchmo or Pinax? -- → Jonathan Hayward, a Senior Web Developer who cares deeply about usability → www.linkedin.com/in/jonathanhayward • jonathan.hayw...@pobox.com → Ajax, CGI, CMS, CSS, HTML, IA, JSON, JavaScript, LAMP, Linux, Perl, PHP, Python, SQL, UI, Unix, Usability, UX, XHTML, XML → With a good interest in the human side of computing and making software and websites a joy to use -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: is there any possibility for two settings.py
Another common technique is to use the local_settings.py way, like so:
# local_settings.py can be used to override environment-specific
settings
# like database and email that differ between development and
production.
try:
from settings_local import *
except ImportError:
pass
---
(Note: I call my settings_local.py so it shows up next to settings.py
when sorted alphabetically)
The above code should be the last thing in your settings.py. What it
does is look for a another settings file settings_local.py in this
case, and uses them as overrides to default settings in your normal
settings.py.
This way you can override settings locally. What we do is don't check
in the settings_local.py into your source control (as that is per
developer), but check in a settings_production.py (or other
settings_*.py) file. Then when we deploy we just copy over
settings_production.py into settings_local.py.

First, you are going to need a null=True on that parent_account field.
Without it an attempt to save an Account with parent_account=None is going

mysql> select * from account;
++--+---+
| id | name | parent_account_id |
++--+---+
| 1 | A1 | 1 |
| 2 | A2 | NULL |
| 3 | A3 | 2 |
| 4 | A4 | 2 |
++--+---+
4 rows in set (0.00 sec)
The query you show returns:
mysql> select account.*, parent.* from account left join account parent on
account.id = parent.parent_account_id;
++--+---+--+--+---+
| id | name | parent_account_id | id | name | parent_account_id |
++--+---+--+--+---+
| 1 | A1 | 1 |1 | A1 | 1 |
| 2 | A2 | NULL |3 | A3 | 2 |
| 2 | A2 | NULL |4 | A4 | 2 |
| 3 | A3 | 2 | NULL | NULL | NULL |
| 4 | A4 | 2 | NULL | NULL | NULL |
++--+---+--+--+---+
5 rows in set (0.00 sec)
The right-side columns coming from the 'parent' table in that result would
more appropriately be labeled 'child', I think, so I'm not entirely sure
this query is doing what you wanted.
It is possible to get the Django ORM to issue a query that seems to match
the intent of how you named those tables in your query, via
Account.objects.select_related('parent_account'). You can check the sql in a
shell:
>>> from ttt.models import Account
>>> from django.db import connection
>>> Account.objects.select_related('parent_account')
[, , , ]
>>> len(connection.queries)
1
>>> connection.queries[-1]['sql']
u'SELECT `account`.`id`, `account`.`name`, `account`.`parent_account_id`,
T2.`id`, T2.`name`, T2.`parent_account_id` FROM `account` LEFT OUTER JOIN
`account` T2 ON (`account`.`parent_account_id` = T2.`id`) LIMIT 21'
>>>
The actual results of that query are:
mysql> select account.*, T2.* from account left outer join account T2 on
account.parent_account_id = T2.id;
++--+---+--+--+---+
| id | name | parent_account_id | id | name | parent_account_id |
++--+---+--+--+---+
| 1 | A1 | 1 |1 | A1 | 1 |
| 2 | A2 | NULL | NULL | NULL | NULL |
| 3 | A3 | 2 |2 | A2 | NULL |
| 4 | A4 | 2 |2 | A2 | NULL |
++--+---+--+--+---+
4 rows in set (0.00 sec)
Those results seem to better match what your query was intended to produce
given how you named the alias, where the right-side columns have information
about the left-side's parent. Or were you really looking for the results of
the original query?
If you described what you were looking for in terms of the Account objects,
someone might be able to help more.

Re: Self Join
Thanks... I'm perfectly comfortable with using foreign keys (and reverse) with the django orm. For basic joins this is fine. For more advanced queries involving complex aggregations (ie-reporting), the orm seems to be pretty useless... looking at the generated sql shows this. It's It's quite easy to produce some nasty queries in loops. I'm guessing the if the simply query above can't be accomplished that I'm better off trying straight sql or sql alchemy.

Do you need a ManyToManyField here? I.E. can a document be in more
than one Publication? I suspect you actually want:
class Document (models.Model):
file = models.FileField()
publication = models.ForeignKey('Publication')
class Publication (models.Model):
title = models.CharField()
Then you can use inline admin forms:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#inlinemodeladmin-objects
In 1.2 there is now a nifty jQuery interface so you can keep adding
documents.
Hope that helps

register model on different App

Assuming that 'groupA' is a model field, there's no such property as
'selections.groupA', because as you've stated, selections is a
queryset - ie a collection of model instances, not a single one.
However in general you'd be better off using Django's forms framework,
which outputs fields for you with all the correct attributes selected.

ANN: django-admin-tools 0.2.0 released
Hello, I'm happy to announce the availability of the version 0.2.0 of django-admin-tools. Django-admin-tools is a collection of extensions/tools for the default django administration interface, it includes: * a full featured and customizable dashboard, * a customizable menu bar, * tools to make admin theming easier. Many bugs have been fixed and new cool features were added in this version: http://pypi.python.org/pypi/django-admin-tools/ This version introduces some backwards incompatible changes: - now, django-admin-tools stores menu and dashboard preferences in the database, so you'll need to run syncdb and to add the django-admin-tools urls to your urlconf. These steps are described in details in the documentation; - You'll also need to add admin_tools to your INSTALLED_APPS for the locales to work (this was not documented in previous versions). The project wiki (including screenshots), code and bugtracker are hosted on Bitbucket: http://bitbucket.org/izi/django-admin-tools/ Django-admin-tools is generously documented, you can browse the documentation online here: http://packages.python.org/django-admin-tools/0.2.0/ A good start is to read the quickstart guide: http://packages.python.org/django-admin-tools/0.2.0/quickstart.html Best regards, -- David -- You received this message because you are subscribed to the Google Groups "Django users" group.
