CKEDITOR not working on certain models
I've used CKEDITOR to turn my models.TextArea() fields into nice editors
for a long time, but suddenly some of my pages throws the following
exception:
Uncaught Error: The specified element mode is not supported on element:
"meta".
I've googled it and tried several solutions, like:
CKEDITOR.dtd.$editable.textarea = 1
CKEDITOR.replace('description');
in my document_ready-section of my page, but it still doesn't work.
The problem only applies to some models and they all share the same
abstract superclass. I cannot figure out why a javascript-package, running
in the browser, handling the exact same html as before should suddenly stop
working because I added some fields using an abstract model with fields not
even being rendered on the page which has now stopped working.
Any hints?

Custom model field and custom widget
Hi, I need to create a custom django model field, a varchar(10) field which has a calculated value set on save on the model using it and then never changed. This should happen automatically. This field should appear as hidden or read-only in forms and it would be nice to handle the render output if the field is accessed in templates. The calculated value generated on save must access the database and look into a seperate table to calculate its value, ie. I need to control the generation of the value it gets.

Is there a complete pinax-based or similar starter project available?
Is there a complete pinax-based (with all the pinax apps installed including templates) or similar starter project available? I'm looking for a starter project with social features similar to facebook and the pinaxproject is the closest I've come so far. Is pinax still in development? What is the current status of the project?

Re: Python 3
My main reason to porting as many as possible of my python projects to Python 3 is proper unicode support.

Re: How to make set background image for printout layout
Do a quick google-search and you'll get plenty of tutorials, for instance http://www.w3schools.com/css/css_background.asp. It seems to require some setup on the client side as well, actually enabling printing backgrounds in your browser settings/print preferences. Read more about it here: http://bytes.com/topic/html-css/answers/465772-how-force-print-css-background-image PS! This question is not django-specific. You'll probably get faster and better results trying in a more appropriate group or forum.

Re: background image for table not apply in printout page and email copy - Django
My first suggestion would be to see what {{ STATIC_URL }} renders as in
your browser. Another thing; if you want to use this template to generate
emails, IP-addresses starting with 192.168.x.x would not work because they
are reserved for internal networks AFAIK. The image would have to be
available for users outside your network for it to be displayed correctly
in an email.
PS! - This problem is not django specific and should be posted to a group
more aimed at webdevelopment in genereal.

Re: How does it all work
I'd take a look at the standard python docs, especially the things about wsgi and httpserver, but this question is not django-specific so you might have better look asking in a more python-specific forum, like comp.lang.python ( https://groups.google.com/forum/?fromgroups#!forum/comp.lang.python ) There's a long way and lots of codelines from a basic "Hello world" webapp to a framework like django, but you'll learn alot by starting with the standard webrelated stuff in standard python.

Re: Please help me in Django
First of all; have you followed the python tutorial and a good grasp on python in general? If not, do a quick read of the python docs before trying to learn django. You'll have to install django after downloading it. Unpack django, cd into the new django-folder and do a python setup.py install Then read the official django tutorial/docs. They are all exceptionally good and should get you going.

Re: Status of Django with Python 3.x
I develop my current project with python 2.7 and 3.3 and so far my problem is not with django being 3.x compatible but critical/popular third-party packages like PIL, django-debug-toolbar etc not being python 3 ready. I hope those and several other packages will be ported to python 3, since Python 3 has some very nice features not available in 2.x and it solves all my unicode issues being a programmer which often deal with non-english characters. So far I've had no problems using python 3 and django.

Re: Suddenly manage.py syncdb fails with 'no such table django_session'
I've later discovered that, in my case, one of my other packages, which

Suddenly manage.py syncdb fails with 'no such table django_session'
I'm using django 1.5.1, python 2.7.3, ubuntu 12.10 and sqlite. My project
has been running flawlessly, but I added a database field, deleted my
sqlite database-file and ran python manage.py syncdb. Now it suddenly fails
with
DatabaseError: no such table: django_session.
I haven't changed settings.py since my last successful run. I've also
googled the problem (and it seem to pop up once in a while), but none of
the solutions provided solved the problem. I've also made the path to the
databasefile absolute, like so:
import os
PROJECT_PATH = os.path.dirname(os.path.abspath(__file__))
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(PROJECT_PATH, 'database.db'),
'USER': '',
'PASSWORD': '',
'HOST': '',
'PORT': '',
}
}
What's going on?

Profiling django apps using Python 3? No hotspot module.
I've tried to find middleware for django or other methods of profiling my django apps, but most of them seem to use the hotspot module and since I use Python 3 and there's no hotspot module in Python 3 I was wondering if anybody out there had a working profiler for django compatible with Python 3? If not I'll try to port one of the ones I've found but why re-invent the wheel? -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: ANNOUNCE: Django 1.5 released
I've been using 1.5rc2 for a while now with no problems so getting a final of 1.5 is great news. I especially like the support for Python 3 since it removes all of my unicode problems. Being a Norwegian programmer having to deal with those damn øæå-characters all the time has been a real pain. Now if only the django-debug-toolbar and PIL could be ported to Python 3 as well all my problems would be solved ;-) Great work!

django-quickview v0.1 released - proof-of-concept/comments wanted
Hi, I looked for django-announcements to post this in, but didn't find at groups.google.com. If this is not the place for such announcements I'm sorry. Anyway; Being somewhat underwhelmed by class based views due to the repetative coding in urls.py etc I tried to see if I could get generic scaffolding and basic views up and running based on a given model in less lines of code. It's pretty simple and not heavily tested, but I'd like to see if any of you has any inital comments before I spend a lot of time on it. The idea is that we always write the same views for alot of our models; a list view, a detail view and add/update/delete. My app/urls.py seem to have repeating patterns for all these views. Generic views, class based or plain functions, do help but I still find all the coding a bit redundant. In essence the templates are the only thing that I really have to code manually. Using quickview you define your model like so : class Person(models.Model): name = models.CharField(max_length=30) age = models.IntegerField(default=10) In views.py: from models import Person from quickview import QuickView class PersonView(QuickView): model = Person And in urls.py: from views import PersonView # after your other patterns: urlpattern += YourView.get_urls() After a little syncdb and runserver you'll have an urlconfig/pattern something like this: myapp/person/list/$ [name='myapp-person-list'] myapp/person/add/$ [name='myapp-person-add'] myapp/person/(?P\d+)/$ [name='myapp-person-detail'] myapp/person/update/(?P\d+)/$ [name='myapp-person-update'] myapp/person/delete/(?P\d+)/$ [name='myapp-person-delete'] where myapp is the app my person-models resides in. Now you define some templates ( list.html, detail.html, add.html, update.html, delete.html ) in /templates/myapp/person/ and you're good to go ;-). Todos: user authentication/login_required etc. and unittests. The code is available at pypi ( pip install django-quickview ) or you can browse the source at https://bitbucket.org/weholt/django-quickview. The testsite-folder at bitbucket contains a working example. -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

Django 1.5 & Python 3 - porting packages to Python3
Hi, As a Norwegian user of Django and python user I've spent countless hours dealing with unicode-problems. As I ported DSE to Python 3 a while ago I also discovered that all my unicode problems were solved if I started using Python 3. Probably old news to most of you, or maybe not even relevant, but it's a make-or-break-situation for me and my potential users and customers. So all my latest django-based projects have been developed using Python 3.3 with great success. But the only problem now is the lack of python-packages supporting Python 3, mainly PIL ( or the pil-fork pillow ), django-debug-toolbar, django-celery etc. Are there any focus in the community on getting packages ready for python3? -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Unicode/Non-ASCII characters in the admin throws exception
Sort of solved this issue myself; my solution was using Django 1.5c and Python 3.3.

Unicode/Non-ASCII characters in the admin throws exception

Re: Middleware manipulating template in response
Hmmm ... is there any other way to achieve the same result ( using a
special template for mobile devices ) without hacking this into each
view? MiddleWare using
https://docs.djangoproject.com/en/dev/topics/http/middleware/?from=olddocs/#process-template-response
for instance?
Anyway, thanks for your input.

How to render a modeladmin dynamically?
In a view, I need to get a modeladmin for a model provided dynamically, change some of the attributes of the modeladmin ( add an aggregated field to the queryset, order the queryset by that field and add a column for that new field in the list_display of the modeladmin ) and render the request using a custom template extending the normal change_list template. I cannot add these things to the modeladmin of the models in question, it has to be done at runtime. -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

I want to make a few foreignkey-fields read-only in the admin after the post is saved, ie when the change-form for that item is opened after the item has been saved the two foreignkeys in question should not be editable.

Re: New to Jdango - What IDE to use?
Me too. I got a open source license for PyCharm for DSE, but it expires tomorrow and I'm not sure if I have to buy a new developer license or not.

Dual license in a django world
It´s been harder and harder to justify the time spent on my spare time projects, none of which generate any income. I´m currently working on a project I believe may have some commercial possebilities and was wondering if I could try a dual license to generate income. For personal or non-commercial use there be a BSD or GPL license and some other license for commercial use ( what license to use ? what to charge? ). I´m not talking about huge license fees ( $99 for a single site ?? ) and have no dream about quitting my day-time job any time soon, but it would be much easier to justify spending time on my django projects if they generated some kind of income. What do you think? How would a dual license be recieved in the django community? Any tip or thought on the subject would be appreciated. -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Introducing: pythonpackages.com
Looks nice, allthough one thing that annoys me quite a bit is how github suddenly becomes the de facto way of logging in everywhere, like djangopackages.com as well. My old login doesn't work there anymore. I use bitbucket, and have no plans or need to switch to github for hosting my projects. Sorry for ranting :-| Still, like the looks of your project :-) So keep up the good work!

Re: Which IDE should I use for Django?
FYI : I got a free time-limited, license for PyCharm using their Open Source Project License ( apply here http://www.jetbrains.com/eforms/openSourceRequest.action?licenseRequest=PCOSL ). Aptana+PyDev seemed heavy and bloated to me. PyCharm is much more focused on pure python development compared to Aptana which oozes Java and PyDev is something added on top. As mentioned, I only got a time-limited license for PyCharm and I'll be looking at other options if I cannot get my license renewed next year. I might also just by a license for PyCharm cuz it's really good :-) Thomas On Mon, Dec 19, 2011 at 1:47 PM, nicolas HERSOG wrote: > I'm using Aptana > > > On Mon, Dec 19, 2011 at 1:37 PM, Anoop Thomas Mathew > wrote: >> >> Hi, >> >> PyCharm is awesome!!!

I think it's been mentioned before in this thread, but DSE was made to help solve problems this.

Caching static images using memcache/nginx
Ok, this might sound a bit off-topic but bear with me. I got a templatetag in an app that generates thumbnails ( django-photofile ). In my templates it might look like this It will generate a thumbnail of the photo in 100x100 in a folder served by nginx for all static content and return an url pointing to the thumbnail, for instance '/static/thumb/4432lkj432kl5k4l26k_100x100.jpg'. This all works nice and dandy, but I want to cache the static photos using memcache, so that when the page is rendered and the templatetag returns the url '/static/thumb/4432lkj432kl5k4l26k_100x100.jpg' nginx will look for it on disk, cache it using memcache and return it so that the next time the page is rendrered it will be read from the cache and not from disk. I got a folder served by nginx with all my static content (js, css, images ), including the thumbnails and I want to cache it all ( using the assigned amount of ram to memcache of course, but I hope this is handled by memcache ). I've read through a few articles about nginx, memcache etc, but still haven't a clue on how to do this. NB! The reason I think/hope this is on topic is the fact I use a templatetag to generate the url etc. Sorry if it's still of topic. -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

Values for ManyToMany-field set in code not visible in admin
I got a model with a ManyToMany-field which is set/populated when saved based on other fields. It can be set in the admin as well. When this field is set in code, and I can see the correct values have been set when getting the object from the database, the correct values in the ManyToMany-field in the change_form for the model are not selected. Selected the values for the ManyToMany-field in the admin manually is saved ok and display ok. What's the difference between setting fields like this in code and doing it in the admin? -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

Where's the code picking apart the info about selected filters in the admin change_list stored in the current session?
Where's the code picking apart the info about selected filters stored in the current session? I see from the source that setting filters in the admin change_list are stored in the session, but I cannot find the code picking the session data apart and building a queryset. Do you have any tips? I want to create a similar piece of code as an alternative change_list in the admin. -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Creating an alternative change_list view for a specific app/model, not extending or overriding
That might work, but I was hoping the change_list was a generic class based view I could subclass and use in my own urls.py for my app, but looking into the source (site-packages\django-1.3-py2.7.egg\django\contrib\admin\views\main.py) of the admin it's not clear at all about how to approach it. Any clues on how to subclass the admin views?

Creating an alternative change_list view for a specific app/model, not extending or overriding
I want to create a view looking and working just like the admin change_list, but using my own template ( based on the admin change_list template ) so that all the filtering you get from specifiying filtering in your adminmodel still works in my new view. I DO NOT want to extend or override the existing one but provide an additional/alternative view to the existing change_list for a specific app/model. I need to change how the elements in the change_list are presented. I'm listing photos, and want a layout like googles image search, not the table-based you get by default in the admin.

Re: can django be used in destop application?
I remember "way back in the day" when Userland was paving way for what was to become xml-rpc, feeds etc ( if I remeber correcly ), the core was a web application running at localhost only. Worked great! I like the idea and allready have a project for something like this. I've tried wxpython, pyqt etc and I still make stuff way faster using django. It doesn't fit every project though. And another thing; there have been discussion about how to distribute django projects and a django project distributed as a single binary, a setup.exe on windows for instance? Sounds nice.

Re: New user - Trouble starting
Have you tried this in the command window ( assuming python is
installed in c:\python27 ):
c:\python27\python c:\python27\scripts\django-admin.py startproject mysite
On windows you might need to run python scripts through python like
shown above. And add c:\python27; c:\python27\scripts; to your path.
The other question, about os.chdir; you'll have to import os before
calling methods defined in it, like so :
c:\python27\python
>>> import os
>>> os.chdir('c:\temp')
Hope this helps :-)
PS! It seems like your new to python as well. I strongly recommend you
dive into python first before getting into django.

Using {% url somenamedview %} in a custom page extending admin templates
My urls.py for my app:
urlpatterns = patterns('',
url(r'^geocoding/$', geocoding, name='geocoding'),
)
I've extended the change_list.html template based on the standard
change_list.html and added this piece :
{% block content %}
{% block object-tools %}
{% if has_add_permission %}
From geocoding
where {% url geocoding %} is the problem. When rendered it says:
TemplateSyntaxError at /admin/locationbase/location/
Caught NoReverseMatch while rendering: Reverse for '' with arguments
'()' and keyword arguments '{}' not found.
So the question is; how can I use the url template tag in templates
extending the standard admin templates and refer to a view defined in
my app by name?
What am I now seeing here?

Re: Django-Registration, How can a beginner work with this 3rd party App?
Have you followed the standard tutorial on https://docs.djangoproject.com/en/1.3/intro/tutorial01/? Look at the http://www.djangobook.com/en/2.0/ ? If you haven't you should start there and not jump directly at a third app. After doing the tutorials and reading through the djangobook the online documentation of third-party apps won't be so cryptic.

Re: "Great circle" using the django ORM?
Ok, now I've created an open project at bitbucket with a public issue tracker so put any of your ideas/comments/bugs there. https://bitbucket.org/weholt/django-locationbase As mentioned I'll look more into this during this weekend and release something next week if I get it working properly. The current implementation doesn't rely on heavy math operations and seems to be database agnostic, only using the orm. This is old code and worked using sqlite. Not sure how well it plays against postgres or mysql. Thanks for your attention once again.

Re: Keep filtering from change_list in admin in custom page?
Hmmm ... Not sure how to do that. You could say I want an alternative change_list page, but not by overriding or extending the existing default one. Do you know of any example or documentation on how to achive this?

Keep filtering from change_list in admin in custom page?
Is it possible to keep the filtering done in an admin change_list in a custom page? For instance, I got a app showing photos where you can filter on camera, width, height, exif-date, iso speed, exposure etc and the admin makes filtering my data very easy using a custom AdminModel. My filter shows up on the right side of the page. But I want to have a custom page for displaying the actual photos using the same filter set in the change_list page.

Re: Komodo IDE better screenshots (worth reading!)
Hmmm ... I've had the same problem using PyCharm; it just doesn't look good, but after a while I stopped noticing and started loving the features of that IDE. Tried PyCharm Cal? The last time I tried Komodo it crashed big time. I'd been using Komodo for a while and the bugs might have been fixed now, but I got a license for PyCharm cuz of DSE and haven't looked at anything else since. Big thanks to JetBrains for the free license. Apply for a license here : http://www.jetbrains.com/eforms/openSourceRequest.action?licenseRequest=PCOSL.

Re: Some thoughts on a package/stack compile system for easy distribution of webapps..
Anything that can make django/python-based webapps easier to deploy is interesting. That's been the huge thing for all my PHP-friends; the ease of deployment. Now if we had something similar for django/python ... it would rock! :-) Used java for some years and war-files worked ok as well. And isn't this a trend nowadays; mac having their DMG-files and discussions in the linux community about making packages distro independant by compiling libs, binaries, resources etc into one executable archive? BTW; could you post the link to showing how the facebook guys are doing this? Haven't seen it.

Argh! How did I miss that? I've restructured my templates and didn't
load my own templatetags! I feel embarrased for wasting your time.

Calling a custom templatetag inside a block/extrahead-block?
I've created a templatetag called {% kolibri_imports %} which I use
the in the head-section of my templates. It imports related to
stylesheets, javascript libraries etc for my kolibri-package. This
works fine when I've control over the base-template I'm extending, but
when I want to extend a template which defines a extrahead for me to
add stuff to, I get an error trying to call my
kolibri_imports-templatetag. Now I want to call that templatetag
inside a
{% block extrahead %}
{% kolibri_imports %}
{% endblock %}
but I get the following error:
Invalid block tag: 'kolibri_imports', expected 'endblock' or 'endblock
extrahead'
So; How can I call a defined templatetag inside my {% block extrahead
%}-block? I've tried
{% block extrahead %}
{{kolibri_imports }}
But that didn't produce anything.
This is probably simple, but ... thanks for you input.

Ann: DSE v.3.0.0 Beta #1
For the impatient:
http://pypi.python.org/pypi/dse/3.0.0.Beta-1
Source at https://bitbucket.org/weholt/dse2/src
Modified BSD license.
New in the 3.x version of DSE is the bulk_update-method, more
intuitive syntax and code clean up.
NB! The new syntax is not backwards compatible so existing code using
DSE must be updated to work.
New syntax:
with Person.delayed as d:
d.insert({'name': 'Thomas', 'age': 36, 'sex': 'M'})
d.update({'id': 1, 'name': 'John'})
d.delete(10) # Deletes record with id 10
I hope the syntax is more intuitive and easy to read. Comments wanted.
Bulk update It takes a dictionary of values to update, requires a
value for the primary key/id of the record, but uses the django orm's
own update method
instead of plain sql to reduce number of statements to execute. This
is helpful when your fields can have a limited set of values, like
EXIF-data from photos or metadata from mp3s.
An example::
with Photo.delayed as d:
d.update({'id': 1, 'camera_model': 'Nikon', 'fnumber': 2.8,
'iso_speed': 200})
d.update({'id': 2, 'camera_model': 'Nikon', 'fnumber': 11,
'iso_speed': 400})
d.update({'id': 3, 'camera_model': 'Nikon', 'fnumber': 2.8,
'iso_speed': 400})
d.update({'id': 4, 'camera_model': 'Canon', 'fnumber': 3.5,
'iso_speed': 200})
d.update({'id': 5, 'camera_model': 'Canon', 'fnumber': 11,
'iso_speed': 800})
d.update({'id': 6, 'camera_model': 'Pentax', 'fnumber': 11,
'iso_speed': 800})
d.update({'id': 7, 'camera_model': 'Sony', 'fnumber': 3.5,
'iso_speed': 1600})
# and then some thousand more lines like that
Internally DSE will construct a structure like this::
bulk_updates = {
'camera_model': {
'Nikon': [1,2,3],
'Canon': [4,5],
'Pentax': [6],
'Sony': [7],
},
'fnumber': {
2.8: [1,3],
11: [2,5,6],
3.5: [4,7],
},
'iso_speed': {
200: [1,4],
400: [2,3],
800: [5,6],
1600: [7]
}
}
And then execute those statements using::
# pk = the primary key field for the model, in most cases id
for field, values in bulk_updates.iteritems():
for value, ids in values.iteritems():
model.objects.filter(**{"%s__in" % pk:
ids}).update(**{field: value})
For huge datasets where the fields can have limited values this has a
big impact on performance. So when to use
update or bulk_update depends on the data you want to process. For
instance importing a contact list where most
of the fields had almost unique values would benefit from the
update-method, but importing data from photos, id3-tags
from your music collection etc would process much faster using bulk_update.

FYI: Inspired by this discussion I've allready started on a similar feature ( allthough somewhat simplified ) for DSE v2.2.0 and you're right; the speed increase is huge using the method described here, even compared to my current solution ( using cursor.executemany ), which is considerably faster than the django orm allready. My testing so far have been using postgresql, not sure how mysql will perform. I expect to release DSE v.2.2.0 with this feature in the next few days. -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

Actually, I started working on something similar, but tried to find
sets of fields, instead of just updating one field pr update, but
didn't finish it because the actual grouping of the fields seem to
take alot of time/cpu/memory. Perhaps if I focused on updating one
field at the time it would be simpler. Might look at it again for DSE
3.0 ;-)

Hmmm, what do you mean by "bulk using update() + F()? Something like
"update sometable set somefield1 = somevalue1, somefield2 = somevalue2
where id in (1,2,3 .)" ? Does "avg 13.8 mins/million" mean you
processed 13.8 million rows pr minute? What kind of hardware did you

Yes! I'm in. Out of curiosity: When inserting lots of data, how do you do it? Using the orm? Have you looked at http://pypi.python.org/pypi/dse/2.1.0 ?

Well, each time a processor is executed it creates a record in the database, with a link to the item it processed. The current system will show if some processor has been used on a given model instance before, but nothing is stopping you from processing that instance again. Perhaps the processor could have some extra property saying if it should only be executed once for any given item? A possible 0.2.0 feature :-).

Multiple forms into one form/trouble accessing form fields
I got several forms I need to display in one page and post to one site. Actually, what I want to do is take all the fields from all the forms and display them as one form and post all input to one view. To avoid collision between the form fields I want to prefix the fields somehow. Say I got three forms: class UserInputForm1(forms.Form): username = forms.CharField() password = forms.CharField() class UserInputForm2(forms.Form): comment = forms.CharField() class UserInputForm3(forms.Form): like = forms.BooleanField() I want to put all fields, from all three forms, into one new form and prefix each field so I know what form the field came from. How can I do that? When I access the fields after creation it appears to be a string. An alternative to this is a FormWizard, but that makes the user click thru a bunch of steps, which could be avoided if I could get all the fields into one new form. -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

Trouble with simple aggregation
Say I got a model like so:
class Article(models.Model):
title = models.CharField(max_length=100)
text = models.TextField()
category = models.CharField(max_length=20)
author = models.CharField(max_length=50)
Article.objects.create(title="Foo", text="Story about foo",
category="adventure", author="jane")
Article.objects.create(title="Bar", text="Story about bar",
category="adventure", author="joe")
Article.objects.create(title="Cheese", text="Story about cheese",
category="adventure", author="joe")
Article.objects.create(title="Perl", text="Story about perl",
category="horror", author="jane")
Article.objects.create(title="Java", text="Story about java",
category="horror", author="joe")
Article.objects.create(title="Pizza", text="Story about pizza",
category="cooking", author="joe")
I've tried to use aggregation to find how many articles written by joe
there are of each category, but so far I'm not getting anywhere.
Desired output:
[
{'category': 'adventure', 'count': 2},
{'category': 'horror', 'count': 1},
{'category': 'cooking', 'count': 1}
]
I just cant get my head wrapped around the orm aggregation, in this is
easy using raw SQL, but I don't want to.

Master/detail in the admin
I've googled and looked at the docs, but haven't found anything related to this scenario: I got a master/detail model, defined like so: class Master(models.Model): title = models.CharField(max_length=100) def details_url(self): return 'Details' self.content_object) details_url.short_description = 'Link to details' details_url.allow_tags = True class Detail(models.Model): master = models.ForeignKey(Master) details = models.TextField() They're exposed in the admin using admin.py. My question is this: 1) How can I make the details_url property in the Master-model so that when exposed in the admin.py a user can click it and go the listing of details and only see details related to that instance of Master-model? 2) If this can only be done using a custom view, how do I get the view to produce a page looking like the rest of the admin? I know I can use the same template code as the admin, but is there a faster way to produce for instance listings like the details in my case? Generic views/classes? 3) Adding Master to list_filter for the detailsAdmin-class is not possible due to the amount of Master-records. Or is it ...? And even if it was possible, how can I set filters from another page, like if I click a link in the change_list for Master-model going to the Details change_list, how can I set the filtering to be set to a specific instance of a Master model? In short; all I want is the have the change_list filtered to only show details related to a specific master-record and reuse as much of the admin-code/featurebase as possible. -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

No, you're not confusing me at all - you're making things very clear
and this is exactly what I wanted; to shed some light on what
difference choosing one license over another can make to your project.
And the point you're making about the non-legal isssues are just as
important for me as I want to "use" the community to make my own
software better. Hmmm ... as one of those copylefters it's somewhat of
a bitter pill to swallow not to use the GPL. Still - I'm a
django/python-user and if I want to succeed and increase my userbase I
might have to put the thinking and philosophy that got me into linux
and open source initially aside and use a license most compatible with
the framework and community I want to contribute to.
Thanks Jacob, this was very enlightening.

Well, I think that's my main motivation for releasing my code as GPL; people are free to use it, modify it, redistribute it, even sell it as part of a larger piece of software, but the only thing I want in return is that their modifications of "my" code are made public for me to use as well so I can benefit from bug fixes, added features etc. So I still believe GPL is the right license for me to use. -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

Hmmm ... maybe, but because of the reusable app focus in django I think some sort of guideline regarding choice of license could be important. This is important to all communities, and in that sense not strictly django related, but I think the number of answers in this thread show that it's something several django users care about - at least to some degree.

How to choose a license for an app or a project?
I've released three django-related packages the last few months, all under the GPL license. Recently somebody asked me about my license choice; "Why not BSD, the same as django?". My reason for choosing GPL is based on the fact that I'm a strong supporter of free software as defined by FSF and GPL is the de facto standard license for that. But the question got me thinking and I wonder what kind of problems I might run into using the GPL, and not the BSD license. Do people really care? Should I care? I think so. What do you people think; How to choose a license and why? -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

CharField with choices gets no ... choices
I got a model looking something like this class SomeModel(models.Model): somefield = models.CharField(max_length=100, choices=somemethod()) The problem is that somemethod, which produces the choices to give in the form in the admin, is called when the module is imported, not when the form instance is created. The result from the somemethod call is dynamic based on custom user defined code and not some static tuple or list. So my question is: how can I get the choices to be set at the time of form creation? Tried overriding the __init__, but then somefield was only available as a string and I could not set any choice-property. -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

Problems using django-taggit; tags disappear in the admin
I got a model using django-taggit. It works great when I add tags in the admin, but when the tags are added in code ( they're read from the EXIF-data in a photo, the keywords part ) - nothing is shown in the admin change form tag-field for the model. I can see the values are stored correctly when I debug the save-method, but when the model instance is shown in the admin the tag-field is empty. >>> from photoapp.models import * >>> d = AdvancedPhoto(title='1', image='/home/thomas/Pictures/test.jpg') >>> d.save() >>> d.tags.all() [, , ] >>> AdvancedPhoto.objects.all()[1].tags.all() [, , ] This works fine. Saving/adding a photo in the admin and then checking it in the shell afterwards: >>> from photoapp.models import * >>> AdvancedPhoto.objects.all()[0].tags.all() [] Hmmm ... what's going on?? -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.

How to use django-taggit in admin.py?
I want to show tags used in a model in my admin.py file, to be able to sort by tag etc. but it crashes with "Caught AttributeError while rendering: 'TaggableManager' object has no attribute 'flatchoices'" if I add 'tags' to list_filter in my ModelAdmin.

My tests using postgres showed a 3X performance gain on inserts compared to using the orm and nearly 10X when doing heavy updates on existing data. It takes care of creating SQL for you and respects default values defined in your models. Thomas -- You received this message because you are subscribed to the Google Groups "Django users" group.
