creating a composite primary key, for a field that isn't in the database...
Hi all, We have a situation where; 1. we have a database that has several tables that use composite primary keys 2. the database *cannot* be munged to add an auto increment integer field (sadly, otherwise this would be a very short post) 3. we don't need to write back to the database 4. we don't need these tables to be represented in the admin application 5. we would lookup records in the table via one or more of the (primary keyed, therefore indexed) composites of the primary key 6. we need a 'primary key' so we can iterate over the objects that are returned from queries so, with that in mind, can anyone suggest a way of 'creating' the key we need for #6 above? I had thought of something like this; # this field does not exist in the database fake_pk = FakePrimaryKeyField(primary_key = True, composites = ['field1' ,'field2', 'field3']) # the following fields do exist in the database field1 = models.CharField(max_length = 10) field2 = models.CharField(max_length = 5) field3 = models.IntegerField() with our 'FakePrimaryKeyField' doing something like; pk = '%s%s%s' % (field1, field2, field3) But I can't figure out how to 'tie in' the fields to tell the _meta part of the model that fake_pk is supposed to be the primary key. Note that 'fake_pk' is *not* in the database at all. Does anyone have any pointers; I've looked at http://code.djangoproject.com/wiki/MultipleColumnPrimaryKeys and http://docs.djangoproject.com/en/dev/howto/custom-model-fields/ and examples of 'custom fields' and nothing I've seen seems to add the vital "I'm the primary key" juice into the mix. Any pointers will be gratefully accepted! Cheers, Tone --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Newcastle, UK Django positions (was "Some django-based jobs available")
Thanks for the rewrite of the subject line Tim, I should have put more location information into the post. I've also added it to django-gigs to get a wider audience. And thanks for being understanding regarding those 'abominably long target URLs' - it's an outsourced operation over which we have no control. They've obviously not heard of SEO! Regarding the jobs: I don't think we can go for telecommuting at the moment, but it's something we're willing to consider in the future. thanks again for your help, Tone On Apr 16, 1:55 pm, Tim Chase <django.us...@tim.thechases.com> wrote: > tonemcd wrote: > > I hope I'm not breaching etiquette here. > > Not particularly...however you may also want to post > onhttp://djangogigs.comto reach the broadest audience. > > One other tip -- though your email CC's Newcastle, UK addresses > and the below redirectors point to the Newcastle pages, it's > helpful to include location information right up front (as well > as any telecommuting option if available) in the body/subject of > the email.

Some django-based jobs available
I hope I'm not breaching etiquette here. We have two jobs going at the moment, where a large proportion of the work will be in Django. To apply, you *must* go through our University online system. Sorry about that. The URLs are; Infrastructure Development Officer: http://is.gd/sJW9 and Web Development Officer: http://is.gd/sJWu All further details (including contact details of people who can give more information) are available at the URLs.

Re: _clone method in list_detail (generic views) loses information?
I should have spent the extra 10 minutes trying out the 'property' solution (rather than the several hours I've spent on the generic view/ pagination code). Adding this code to the model works perfectly well. def _link(self): from settings import ACCESS_PATH if self.mimetype == 'url': return '%sredirect?location=%s' % (ACCESS_PATH, self.uuid) else: return '%sdownload/%s/%s' % (ACCESS_PATH, self.uuid, self.filename) link = property(_link) I wouldn't mind, except I've used properties extensively before and it never occurred to me to use them this time sigh.

_clone method in list_detail (generic views) loses information?
Hi, I'm used to doing things like this; resources = Resource.objects.all() for resource in resources: if resource.thetype == 'url': resource.link = '/access/redirect?location=%s' % resource.uuid else: resource.link = '/access/download/%s/%s' % (resource.uuid, resource.filename) It means that more logic is shunted from the template to the view. This helps some browsers to determine what they should do with a link (we use file-disposition and mimetype etc - but we still need to do this) I've just wired this up to generic views and find that this line (46) in django/views/generic/list_detail.py causes the 'link' attribute to disappear. (I put 'queryset[0].__dict__' before and after the line and 'link' had dissappeared) 46:queryset = queryset._clone() Is this expected behaviour? If so, should I be doing things in a different way (property on the model perhaps)?

Re: Django new comments framework error
...and of course, I find that http://code.djangoproject.com/ticket/8221

That should help clear up an awful lot of confusion.
As of r8672, it's in the trunk.

Short summary: maybe your named url regexes aren't matching the
variables passed to them in the {% url ... %} tag.
Apply the patch from http://code.djangoproject.com/ticket/8221 and
you'll know for certain if that's it.

Re: Random NoReverseMatch
I've just come across this ticket, http://code.djangoproject.com/ticket/8221,
which has a patch attached. I've just applied the patch and crippled
my url regex again to re-create the error. This is what was reported
this time;
NoReverseMatch: Reverse for 'MBBS.agenda_today_group' with arguments
'(u'st4gp4&5',)' and keyword arguments '{}' not found.
Now *that* would have saved a heap of time earlier on today ;)
Ticket 8221 is down for the 1.0 release, so hopefully, we'll have that
in trunk ready for the big release of V1.0.

Re: site using Django/mod_python/apache2 randomly showing "It worked!" page
Does Apache have mod_wsgi? If so, you can get them to make a change to your .conf file as detailed at http://code.google.com/p/modwsgi/wiki/ReloadingSourceCode This means you only need to 'touch' the .wsgi file specified by the WSGIScriptAlias to get your Apache process to restart. Works a treat! I moved away from mod_python for the very reason you've outlined. The wealth of information on mod_wsgi is immense!

Re: Random NoReverseMatch
Well, this bit me a while back when I svn-up'ed from trunk and I got
fed up of changing my django.pth to point to trunk_r7971, so I was
determined to get it sorted out.
The first thing is that the NoReverseMatch error seems to be a catch-
all for a variety of exceptions, so if you can, check out your imports
as Koen outlines below.
However, I think that in this case it is far more likely that you have
some data that is triggering the NoReverseMatch exception, as you say
it happens randomly, and I think what is happening is your arguments
to {% url ... %} are not compatible with what your named url is
expecting to see.
This is what happened to me; my urls are of the form;
today//agenda
where is letters (upper and lowercase), numbers and '-', so
these are valid stgp01, st2gp2-18 etc.
I used this match to begin with;
url(r'^today/(?P[\w,-]+)/agenda$
from http://python.about.com/od/regularexpressions/a/regexprimer.htm
you can see that \w handles alphanumerics and _.
This is what killed it;
/today/st4gp8&9/agenda
With r7971 this would not have been a problem (well actually it would
have been a problem because the URL wouldn't work), but at least it
wouldn't give you an error. Now it does (it was changed in r8211, see
http://code.djangoproject.com/wiki/BackwardsIncompatibleChanges for
more details).
The solution for me was to include & and friends into the regex, so I
added \W as well (the above URL has details).
My final URL pattern is url(r'^today/(?P[\w,\W-]+)/agenda$ and
this works just fine.
I don't know what you're matching, but I'd hazard a guess that what
you're pumping out is not compatible with what your URL regex is
expecting to see.
This seems like a prime example of something that needs a slightly
more descriptive error message, but whether that's possible or not, I
don't know (I did dig around in urlresolvers.py, but it went rapidly
over my django-fu).
Hope this helps,
Tone

Re: ADMIN_MEDIA_PREFIX setting weirdness
This may not be relevant, but I've had no end of confusion with ADMIN_MEDIA_PREFIX. What I've found is this; If you're running the development server, the value of ADMIN_MEDIA_PREFIX is effectively ignored. Look at the code in django/ core/servers/basehttp.py, in AdminMediaHandler and you'll see it serves the media up from the location that django is installed from. However, once you use something like fastcgi or mod_python to serve your content, the value of ADMIN_MEDIA_PREFIX is used, and you need to make sure it's pointing to something (of course, Apache/lighttpd etc rewrite rules can be used to tidy things up). This is all based on the description of what ADMIN_MEDIA_PREFIX does by Malcolm Tredinnick:- http://groups.google.com/group/django-users/msg/df0605a05a747e57 hope this helps, tone On Sep 28, 6:35 pm, omat <[EMAIL PROTECTED]> wrote: > Hi, > > This looks like a bug to me. > > When I set ADMIN_MEDIA_PREFIX = '/media/', some weird things happen, > such as: > - I get different 404 messages for non existing files > - the served files does not appear in the development server console > - the files under \site-packages\django\contrib\admin\media\ are > served, instead of the /media/ folder in under my MEDIA_ROOT > > But when I set ADMIN_MEDIA_PREFIX = 'http://localhost:8000/media/' > everything works as expected, that is: > - standard 404 messages > - served files appear in the console > - files under MEDIA_ROOT/media/ are served > > Any idea why this difference exists? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: How to create a simple PDF
I was going to suggest looking at a Java-based system called Jasper reports, which we got into because we found ourselves spending too much time writing ReportLab scripts to generate PDFs (Jasper has a wysiwyg interface and connects to databases directly). However, seeing Chris' email reminded me of RML, which was designed by the ReportLab guys and *much* easier to use than ReportLab itself. We looked into that and were very interested, but the licencing fee was too high for us (the RL guys do a lot of work for finance houses, and they have plenty of cash). I don't think TinyRML is as powerful as RML, but you can't beat the price! Conrad, I think you should definitely look at Chris' solution - we've done a *lot* of work in ReportLab and as Kenneth says, it's not trivial, whereas Chris has made it all look easy ;) I particularly like the fact that the PDF templates (in RML format) are django templates - it reinforces the idea that django can do stuff other than HTML.

Re: Simple CAS 1.0 authentication
Brian, Just a quick note to say *thankyou very much* for making this available. I installed it into one of my development sites over the weekend and it works like a charm. I only tried the middleware version (which is probably more appropriate for an authentication backend) and found it to work just fine. In the end, all I had to do to get CAS authentication operational on my site was to change one line in settings.py and two in urls.py (once I'd installed cas into django.contrib). If that doesn't show the power of middleware then I don't know what does ;) Again, thanks heaps for making this available - it's done the business for me!

advice needed - how to manage 100+ django sites in a scaleable, manageable setup
Hi all, We're about to put our first django site online on Monday, which is a major departure for us. We currently host 100+ Zope instances, almost all of which are load balanced over more than one physical server using pound. Our databases are MySQL and increasingly, PostgreSQL, and these are also load balanced using pound. At the moment, the django site is running using mod_python and Apache 2.0, but this is not the way that our other systems run - we use pound and Zope clustering software (ZEO) to enable us to clone and slot in another Zope instance into the cluster as needed. This system has grown organically over several years, for example, for quite some time, we did no load balancing at all, even for our most heavily used systems. What I'd really like to know is how we could replicate this level of functionality with a django setup. Any ideas? I can provide more details if people would like to know, but really at the moment, I'm just trying to get a handle on what's possible. many thanks in advance, Tone --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Having problems getting started with Zyons
Hi all,
I'm trying to get the Zyons community/bulletin board system up and
running - we think it could be extremely useful for a large part of our
education community, and will assist us in migrating from Zope to
Django. Trouble is, I can't get it to work on my machine (MacBook Pro,
Python 2.4.3/MySL 4.1.18-standard)
I get this error on pointing at the root;

The actual SQL generated is;

Is this a simple thing that I can fix (ie I've done something stupid),
or do I need to include more traceback information?

Re: Limiting selection in admin pages [NEWBIE]
Sorry Q, I forgot to add the WorkGroup definition; class WorkGroup(models.Model): groupName = models.CharField(maxlength=50) def __str__(self): return "%s" % self.groupName That's where the 'groupName' is coming from in my lookup. I'm using rev 2900 (ie the merged MR trunk) so I don't think there's any other magic going on. I'm guessing your definition of WorkGroup (or whatever your foreign key is) has a field 'name'. It may be that the lookup mechanism is checking for the 'name' property, but without digging into the source, it's just a guess on my part.

Re: FileField fieldRequired error
Take it easy You'll not make friends if people think you're
shouting...
This works for me with an ImageFile field. FileField should work the
same...
Template snippet:
Title: {{ form.title }}
Post date: {{
form.postdate_date }} Post time:
{{ form.postdate_time }}
Tags: {{ form.assoc_tags
}}
Image: {{
form.image_file }} {{form.image}}
Body: {{ form.body }}
And this view;
Post is the name of my model, be careful to not confuse it with POST.
def upload(request):
# get all the content
# for now, just assume a file is uploaded
files = request.FILES
for uploaded in files.keys(): # key is from , ie image_file
filedata = files[uploaded]
filename = filedata['filename']
content_type = filedata['content-type']
content = filedata['content']
body = request.POST.get('body', '')
assoc_tags = request.POST.getlist('assoc_tags')
title = request.POST.get('title', '')
manipulator = Post.AddManipulator() # Post is my model name
new_data = request.POST.copy()
new_data.update(request.FILES)# definitely needed
new_data['poster_id'] = str(request.user.id) # following needed
to make sure manipulator.save passes off without a hitch
new_data['poster'] = request.user.id
new_data['slug'] = slugify(title)
new_data['totalscore'] = 0
new_data['image'] = filename# this doesn't look
like it should work, does it?
new_data['uuid'] = 'no data entered'
manipulator.do_html2python(new_data)
new_post = manipulator.save(new_data)
return HttpResponseRedirect('/electives/')

Re: Django vs Rails
That's a really good screencast - the Java-based frameworks come out particularly badly (but the author is looking more at the rapid applications development model, where multiple XML configs and compiling certainly doesn't help matters) I was surprised at how well Zope (Plone actually) comes out of it. I guess he was using Archetypes to do the heavy lifting - I've found plone to have a *very* steep learning curve. Django comes out well, with the caveat that Simon mentions re: i18N. Recommended - it's 37" long though and 300+ megabytes... Cheers, Tone --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Feed rss and xml
Err, before running off into XSL land, you might want to try a few things beforehand. Why not add some CSS to your XML feed, many newer browsers will render the XML using the CSS to give a human-readable output. I'd definitely do that before getting involved with XSL transforms (you'll likely have to call an XSLT processor programme from within your view methods - not a trivial thing to do).

Re: Advice on 'voting' system that excludes previous voters
Replying to your own posts is so uncool ;)
Here's something that works, I have no idea whether it's efficient or
not - any ideas?.
This code is in my views.py
Essentially what's happening is that I'm adding another attribute
called 'alreadyvoted' to each one of the 'posts'. This is then
available in the template as post.alreadyvoted in this format,
{% for post in posts %}
{{post.alreadyvoted}}
{% endfor %}
def index(request):
# get Tags and Posts
tags = Tag.objects.all()
posts = Post.objects.all()
def alreadyvoted(post, voterid):
voters = post.vote_set.all()
for voter in voters:
if voter.id == voterid:
return True
return False
for post in posts:
post.alreadyvoted = alreadyvoted(post, request.user.id)
# as we're using a RequestContext, pretty sure that user variable
is predefined.
context = Context(request, {'debugMe': True, 'tags': tags, 'posts':
posts,
'tagcloud':makeTagCloud(), 'request': request, 'user':
request.user})
return render_to_response('electives/index',
context_instance=context)
Hope this helps someone, and if there's a smarter way of doing this,
I'd really like to know ;)
Cheers,
Tone

Advice on 'voting' system that excludes previous voters
Hi all,
I am working on a voting system based on a model with three classes,
Post (the thing people will be voting on), Vote (the vote itself) and
Person (the voter and the poster). I've put simplified version at the
end of this post.
To get all the posts, I use
posts = Post.objects.all()
in my views.py and this is passed into the template.
In the template I'm basically doing this
{% for post in posts %}
{{post.title}}
Posters:{% for poster in post.vote_set.all %}
{{poster.voter}}, {{user}} {% ifequal poster.voter user %}
already voted {% endifequal %}
{% endfor %}
{% endfor %}
Which doesn't work (in that the 'already voted' text is never shown,
even when I know that {{user}} has voted for a particular post). I have
the feeling that I'm not doing this right from the get-go, perhaps I
should be loading up the posts variable in my views.py.
Does anyone have any pointers on how to do this? I've been banging my
head against a wall trying to get this sorted (this was relatively easy
to do in Zope).
Cheers,
Tone
The models are here:
class Person (models.Model):
student = models.ForeignKey(User)
nickname = models.CharField(maxlength = 20)
def __repr__(self):
return "%s" % self.student.__repr__()

slug = models.SlugField(
'Slug',
prepopulate_from=('title',),
help_text='Automatically built from the title.',
primary_key='True'
)
assoc_tags = models.ManyToManyField(Tag)
title = models.CharField('Title', maxlength=30)
postdate = models.DateTimeField('Date')
image = models.ImageField(
'Attach Image',
upload_to='postimgs',
blank=True
)
uuid = models.CharField(blank=True, maxlength=36, help_text = 'This
is a unique identifier for the image for this post') # This is the uuid
of the image.
body = models.TextField('Body Text')
poster = models.ForeignKey(Person)
def __repr__(self):

(1, 'up'),
)
post = models.ForeignKey(Post)
voter = models.ForeignKey(Person)
value = models.IntegerField(choices = VOTE_CHOICES)
votedate = models.DateTimeField('Vote date')
def _post_title(self):
post_title = self.post
if post_title is None:
return "No post title"
else:
post_title = post_title.title
return "%s %s" % (post_title, self.value)
post_title = property(_post_title)
def __repr__(self):
return "%s" % self.post_title

Re: Relationship with self with relationship data in app.py
I wish I'd known about the forward reference method a bit earlier, would have saved a lot of hair-pulling. It seems that most of my hiccups with django seem to be related to data models and accessing that data using the ORM (I'm a Zope guy, and you don't do it that way there...)

Re: Brain fried - need help with M2M and MR
Yes, of course - it all makes sense now after some sleep.
Thanks for the hint on ipython Luke, I've had it installed for ages wth
django, and it is *extremely* helpful, but I just couldn't see the wood
for the trees.
For the record for anyone else doing this, here's how I did it with
generic views and magic removal
urls.py
info_dict = {'queryset': Tag.objects.select_related(), 'slug_field':
'slug', 'template_name':'electives/tag_list'}
...
(r'^electives/tag/(?P[0-9A-Za-z-]+)',
'django.views.generic.list_detail.object_detail', info_dict),
and electives/tag_list is (essentially);
{% for post in object.post_set.all %}
{{ post.title
}}
{% if post.image %} {% endif %}
{{ post.description|truncatewords:80 }}
Posted on {{ post.postdate|date:"F
j, Y" }} Tags: {% for tag in post.tag_set.all %}{% if not
forloop.first %}, {% endif %}{{ tag.title }}{% endfor %}
{% endfor %}
Thanks a lot for the help, it's much appreciated,
Tone.

Re: Brain fried - need help with M2M and MR
<2001>
It's all so much clearer to me now...
My headache has cleared up now, and I can see exactly what you mean
Derek. It works fine now, thanks!
Here's a snippet for others;
urls.py
(r'^electives/tag/(?P[0-9A-Za-z-]+)',
'site1.elective.views.tag'),
site1.electives.views.tag
def tag(request, tag):
# get all posts that mention this tag
thetag = Tag.objects.get(slug=tag)
posts = thetag.post_set.all()
context = Context(request, {'debugMe': True, 'posts': posts,
'tagcloud':makeTagCloud(), 'request': request, 'user': request.user})
return render_to_response('electives/taglist',

Brain fried - need help with M2M and MR
My head hurts (really, it does, I think I've given myself a headache
trying to figure this out)
I'm using magic-removal and have a 'simple' model for a tag-based
posting system (which will turn into a voting and image uploading
system).
Here's the model (slightly cut down to save space);
class Tag(models.Model):
slug = models.SlugField(
'Slug',
prepopulate_from=("title",),
help_text='Automatically built from the title.',
)
title = models.CharField('Title', maxlength=30)
description = models.TextField(
'Description',
blank = True,
help_text='Short summary of this tag'
)
def __repr__(self):
return self.title
and
class Post(models.Model):
slug = models.SlugField(
'Slug',
prepopulate_from=('title',),
help_text='Automatically built from the title.',
primary_key='True'
)
assoc_tags = models.ManyToManyField(Tag)
title = models.CharField('Title', maxlength=30)
What I want to do is get a list of posts that are related to a tag. I
know it can be done because Ross Poulton has done it at
http://www.rossp.org/blog/2006/feb/17/building-blog-django-3/
His setup is slightly different though, in that he's using the trunk
and generic_views. I'm trying to keep using MR as "it's the future" ;)
Trouble is, I just cannot get my head around the proper incantation in
MR to do this...
I've not done generic_views in MR yet, so if there's a HowTo or
something around (example would be great), then I'll leap into that.
If that's not possible, I'd just appreciate some pointers to any code
that might help?
Cheers,
Tone

Re: mini-wiki advice
Here's something I'm using in an application - it uses the 'Textile'
engine so that the person entering the markup doesn't have to worry
about HTML. Works well!
It's in a model, and this is all MR by the way;
class Person(models.Model):
...
expectations = models.TextField('Expectations body', blank=True)
expectations_markup = models.TextField('Expectations body as HTML',
blank=True, null=True)
...
def save(self):
import textile
...
self.expectations_markup = textile.textile(self.expectations)
...
super(Person, self).save()
Also check out http://e-scribe.com/news/171 from Paul Bissex - a Wiki
in 15-20 lines of python (and Django!) ;)

Re: How to exclude in limit_choices_to (magic removal)
I tried __ne and (somewhat naively) __exclude and neither works.
The Wiki documentation at
http://code.djangoproject.com/wiki/RemovingTheMagic#Changedtemplatenamesingenericviews
says that 'ne is no longer a valid lookup type'
I had a look around and in the MR version of the file
db/backends/mysql/base.py we have this;
OPERATOR_MAPPING = {
'exact': '= %s',
'iexact': 'LIKE %s',
'contains': 'LIKE BINARY %s',
'icontains': 'LIKE %s',
'gt': '> %s',
'gte': '>= %s',
'lt': '< %s',
'lte': '<= %s',
'startswith': 'LIKE BINARY %s',
'endswith': 'LIKE BINARY %s',
'istartswith': 'LIKE %s',
'iendswith': 'LIKE %s',
}
Whereas in the 0.91 release (at the location core/db/backends/mysql.py)
we have this;
OPERATOR_MAPPING = {
'exact': '= %s',
'iexact': 'LIKE %s',
'contains': 'LIKE BINARY %s',
'icontains': 'LIKE %s',
'ne': '!= %s',
'gt': '> %s',
'gte': '>= %s',
'lt': '< %s',
'lte': '<= %s',
'startswith': 'LIKE BINARY %s',
'endswith': 'LIKE BINARY %s',
'istartswith': 'LIKE %s',
'iendswith': 'LIKE %s',
}
I guess you could add the line into your own MR installation, but there
might be some side-effects (I did it as a test and got repeated entries
- I've since edited it out)
Anyone know the proper way of doing this?

Tone

Re: limit_choices_to
Well Luke (the author) might have a better idea than me, but I'll have a go ;) Put it anywhere in your applications folder structure, Luke chose cciw/middleware because his app is called 'cciw' - but it doesn't matter because in his model file, he has the following... .. ... import cciw.middleware.threadlocals class ApplicationAdminOptions(AdminOptions): .. Now,I haven't used this mind, so no gaurantees it will work, but as Luke is one of the core django developers, there's a better than evens chance that it will ;) Cheers, Tone --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: SQL Debugging and limit_choices_to in MR Branch
Thanks for the patch ChaosKCW,
I still can't get this to work though,
pa = models.ForeignKey("self", blank=True, null=True,
limit_choices_to = {'groups__exact' : 'Administration'}) # PA for
this person
I'm now getting mesages about an m2m table not existing.
What I'd like to do is something like
limit_choices_to = {'WorkGroups.groupName__exact' : 'Administrator'}
but that returns "Cannot resolve keyword 'WorkGroup.groupName' into
field".
thanks for any help,
Cheers,

Re: SQL Debugging and limit_choices_to in MR Branch
I have a similar problem with limit_choices_to and MR.
Within the admin interface I'd like to limit the choices for a persons
'personalAssistant' to come from a group called 'Administration'. At
the moment, it doesn't work, all 'Persons' are shown in the
'personalAssistant' popup, and I know I have some that have the
WorkGroup 'Administration'. Here's my model:
class WorkGroup(models.Model):
groupName = models.CharField(maxlength=50)
def __repr__(self):
return "%s" % self.groupName
class Person(models.Model):
firstName = models.CharField(maxlength=50)
lastName = models.CharField(maxlength=50)
title = models.CharField(maxlength=20, blank=True)
null=True)
groups = models.ManyToManyField(WorkGroup, related_name = 'groups',
blank=True)
coordinator = models.ManyToManyField(WorkGroup, related_name =
'coordinator', blank=True)
personalAssistant = models.ForeignKey("self", blank=True,
null=True, limit_choices_to = {'groups_groupName' : 'Administration'})
# PA for this person
But the limit_to_choices isn't limiting choices at all.
Does anyone have any pointers?
Cheers,
Tone

Re: Advice on developing with django for a team of 10+
Our developers get involved in a lot of projects Tom - so it's almost a combinatorial explosion situation! I've been using subversion to get the latest django updates and have found it pretty approachable, so that's a big plus. We've not decided on django yet ;) there's still Zope3, TurboGears and RoR to consider, but I've been very impressed with django and to be honest, the learning curve WRT Zope3 just seems *waay* too high. RoR is a different language altogether - so that's going to be a high hurdle. Thanks for your comments!

Advice on developing with django for a team of 10+
Hi, Hopefully, by this time next week we will have a dedicated server (Sunfire 4100) running django and support stuff. I'd then like to start developing new applications as soon as possible after that. I've been playing around with django on my AlPB for about 6 months now and have learnt a fair bit, but I really need some pointers for how a group would develop with django. Our background is in Zope, and virtually all the development on that platform takes place using a browser, with a relatively small amount of python scripting taking place on the server. We have quite a sophisticated Zope setup, running circa. 150 services with development servers and clustering of deployment servers, so we're no babes in the woods when it comes to web development ;) With people working with browsers, it means that people do not have the source of the site on their local machines (they may have some python scripts lying around, but the bulk of the site is held on the server). This has been handy in the past, as no one person can screw up the application (well, they can, but they have to try a bit!) We use a variety of machines to develop on, I and several others use a Mac, most people use PCs and we have some people using RH linux as their desktop. This has not mattered in the past when we've been using browsers, but with something like django, things may be different - I don't know. I see the following scenarios, and would really appreciate a heads-up if I'm way off base. 1. People ssh into the box and edit the source code directly. This is going to mean a lot of hassle re: unix permissions and over-writing of other peoples work. The editors and other tools on the server are probably going to scare some of my people off as they use GUIs - browsers - to develop with at the moment. Telling them that emacs is the one true editor (tm) is not going to cut it I'm afraid ;) This does have the advantage that the server is the only place where the source code lives. 2. People use editors on their desktop machines and sftp to the box. Same problems as #1 wrt permissions, but at least they get an editor they're happy with. Source is now distributed. 3. People run their own local django installations, and commit changes to a development server for testing before those changes are sent to the deployment server. This means each individual user machine has to have access to the databases and keeps a copy of the source on their machine. It also means a lot of django trunk duplication on each machine (I guess we could do an 'svn up' where the target is our own django installation on the server - nice thought!). We have very little experience of using svn etc however. Our people would normally work on several projects, and with option #3, we would have to have all those projects on their local machines. I don't want to ramble on here, as I'd like to know if I'm missing something really obvious already! So, if anyone is doing something like this, I'm all ears!

Re: Changing filenames on an upload...
Ahhh... Should have said I was using magic-removal, and that this is within the admin interface. The reason for the uuid filename is because I'm thinking of having a lot of files uploaded and I could end up with dozens of files called 'TEST.DOC' and this is one way of guaranteeing that the filename will be unique within that directory. It's based on some Zope code that works very well. We basically add the filename onto the end of the uuid and get something like cetl/3C644E61-E4EF-451E-BF03-804D9A7692D5/presentation.ppt. The file is actually stored in the filesystem using the uuid - we squirt it out as a binary stream having first set it's mimetype. Having the filename tacked on the end helps browsers to figure out what the file is and act accordingly. If Django is always going to save the file using the uploaded file name, I might have to skip uploading files using the admin interface. I should say that I do have an application where all this uuid stuff is working just fine with standard file uploads (although I've not ported that to magic removal...) Thanks for the help though Malcolm, you've saved me quite a bit of effort in digging around!

Changing filenames on an upload...
Hi all,
I have this model
class Photo(models.Model):
name = models.CharField(maxlength=20)
image = models.ImageField(upload_to="cetl/")
def save(self):
import commands
self.image = 'cetl/%s' % commands.getoutput("uuidgen")
super(Photo, self).save()
def __repr__(self):
return '' % self.image
class Admin:
list_display = ('name', 'image',)
As I want the filename to be unique within the directory. Thing is the
save() method is not doing what I thought it would!
What gets saved into the directory is this;
cetl/image1.jpg
What gets saved into the database is this;
| id | name | image |
++--+---+
| 11 | database | cetl/3C644E61-E4EF-451E-BF03-804D9A7692D5 |
++--+---+
So where am I going wrong? ;)
Cheers,
Tone

Re: table needs all fields filled in?
Hi, blank=True should allow you to submit a partially-filled form, but you have a lot of core=True fields in there as well, perhaps you have too many? From the Model Reference documentation http://www.djangoproject.com/documentation/model_api/; core For objects that are edited inline to a related object. In the Django admin, if all "core" fields in an inline-edited object are cleared, the object will be deleted. It is an error to have an inline-editable relation without at least one core=True field.

Re: Request for ideas
Authentication. There's some documentation, and it's pretty good. Having more won't hurt though and will definitely help the people considering migrating to django with their decisions. I'd suggest external (ie different to the settings.py 'django' database) MySQL/Postgres databases, LDAP and (if you feel up to it!) Shibboleth. Cheers, Tone
Re: Paginator Documentation
I got to a similar state, but I couldn't figure out what the template should look like! (dumb, I know). Do you have an example you can post? I'm trying to implement parts of the admin system into my own apps, and the paginator is a core part of that (looking at migrating from Zope, and the 'batch' stuff there is quite neat), so this would be a real help! Cheers, Tone
Re: You want some of that 'adminy' goodness in your own apps?
Hadn't thought of that Brian, I'll have a go at putting something a bit more sensible into the Wiki (I was in a hurry to go to a meeting and wanted to get the content online somewhere before it left me completely!). Come to think of it, I may try diffing against the original docs and submitting it as a ticket (first attempt at that though...) Cheers, Tone
You want some of that 'adminy' goodness in your own apps?
Here's what I've found...
Start with the very useful tutorial at
http://www.djangoproject.com/documentation/forms/ - in general it's
very helpful, but there are some small gaps in the documentation, which
would certainly have helped me
#1: I'd emphasize that this document
(http://www.djangoproject.com/documentation/forms/), will help
djangonauts get a lot of the adminy goodness into their own apps. Big
win to the django team.
#2: The date and time javascript widgets are what I wanted most of all.
It would be handy if the example model included a DateTime field.
Here's what I have;
startdate = meta.DateTimeField(db_column='start_date') # there
were too many underscores, I wanted to keep it simple!!
This is represented in the form template like this;
Start Date:
{{ form.startdate_date }} {{ form.startdate_time }}
{% if form.startdate.errors %}*** {{
form.startdate.errors|join:", " }}{% endif %}
The big thing here is that the field 'startdate' is expanded out in the
form, _date and _time are made available (this may have been where I
went wrong, my initial attempt had {{ form.start_date }}, but I never
saw any content in the form).
#3: There seems to be an error in the code for loading up an edit_form.
The example document has this;
if request.POST:
new_data = request.POST.copy()
errors = manipulator.get_validation_errors(new_data)
if not errors:
manipulator.do_html2python(new_data)
manipulator.save(new_data)
# Do a post-after-redirect so that reload works, etc.
return HttpResponseRedirect("/places/edit/%i/" % place.id)
else:
errors = {}
# This makes sure the form accurate represents the fields of
the place.
new_data = place.__dict__
*no way* could I get this to work, I had to do this instead
if request.POST:
new_data = request.POST.copy()
errors = manipulator.get_validation_errors(new_data)
if not errors:
manipulator.do_html2python(new_data)
manipulator.save(new_data)
# Do a post-after-redirect so that reload works, etc.
return HttpResponseRedirect("/resources/edit/%i/" %
resource.id)
else:
errors = {}
# This makes sure the form accurate represents the fields of
the place.
#new_data = resource.__dict__
new_data = manipulator.flatten_data()
Note that
new_data = resource.__dict__
is replaced with
new_data = manipulator.flatten_data()
Ok, nearly there, but could I get the clock and calendar widgets? Nope
- I used Xylescope to check on the CSS, I used alerts in the Javascript
etc. etc. and then I found it was stopping on gettext... Some
additional digging provided this jewel; i18n.txt in the docs.
Add this;
(r'^jsi18n/$', 'django.views.i18n.javascript_catalog', {'packages':
'django.conf'}),
to your urls.py for your application, make sure that your header HTML
looks *something* like this;
And Bob's your Uncle, Fannys your Aunt (ie the javascript widgets
work).
Hope this helps ;)
Cheers,
Tone

Re: assign or rename a variable in templates

Re: FileField :: mx file size
So does this happen *before* the file is uploaded - I mean when the submit button is pressed? It seems that Django will be getting information from the browser about the length of the data to be uploaded - and that's something I've always thought HTTP could not do... If so, this is *very* interesting (it's interesting anyhow, because of the validator!). Cheers, Tone
Re: image field update impossible.
I guess a validator would sort things out in this situation. However, this is a general problem - uploading files that have the same name (test.doc, figures.xls, etc.) - how do you know that its ok to overwrite the file with the same name? If it's just you uploading files, you're probably ok, but if this is to be a shared system, you'll need to be more watchful. If you're not careful, you'll end up writing a content management system. Cheers, Tone
Re: FileField :: mx file size
I didn't think you could do that - find out the size of an file to upload *before* it's uploaded, and act upon it. I've wanted to do that in CGI, Perl, PHP and Zope, and never figured out how to do it (it would have saved a few embarrasing incidents in the past; the 170 Mbyte powerpoint, the CD!! that was uploaded, etc. etc.) I'd like to see the validator you come up with Arthur! Cheers, Tone
Re: How do I get POST variables in my template
* thud! * - the sound of a rather large penny dropping. Many many thanks Adrian, it's making a *lot* more sense now (how on earth did I miss that page in the docs!) I *think* that the reason why my request.POST was coming though as empty (even when I clicked submit) is that I had no name for my submit button, ie . If I made no selections on my form (just checking), and clicked submit, I expected POST to have *something* in it, but it didn't..., and as I was doing a test of the form if request.POST: blah() then blah() wasn't being called. A real d'oh! moment. thanks again (and to the.ech0, Eric and Amit) - now onto the next hurdle! :) (I just hope I've understood the situation clearly enough) Cheers, Tone
Re: How do I get POST variables in my template
Hello again Amit,
I'm trying to get the Zen of Django, by using methods I used to use in
Zope ;)
Essentially, I used to have statements like this sprinkled around my pages to check that
form-based variables where being passed through correctly. Zope put
into a namespace called 'form', but also made them available in the
main namespace. The request namespace was populated with all POST and
GET variables. Django presents POST as POST:, so I
don't know what variables are in the POST namespace.
In Zope, what I'd do is this;
...
then in 'dostuff', I'd do;
or more likely and get the whole namespace -
actually I'd use PageTemplates, but they're more verbose than dtml ;
With Django I need to know what's in the REQUEST variable and display
it explicitly, eg {{ request.FILES.file.filename }}
Simply doing a {{ request }} doesn't show the variables that are passed
through from a form - something I used to rely on heavily in Zope-land.
I guess my Django Zen level isn't high enough (yet).
Cheers,
Tone
Re: How do I get POST variables in my template
Thanks for the info 'the.ech0' - it seems that's what I have to do. I guess what I was after was functionality like in Zope, where the entire HTTP Request object is dumped, along with environment and other variables. GET and POST are all expanded out too. With the Zope PageTemplate code that Stefan contributed, I can get that functionality back, but only by using PageTemplates ;) It does seem to me that for something as 'busy' as POST and GET, there ought to be some functionality for inspecting what's in the object... Still on the learning curve for Django - thanks for the advice though. Cheers, Tone
Re: Upgrading models...
That's a very interesting thought Todd. I don't know enough about Ruby to follow the code properly, but the idea is pretty neat...
Re: Dreamhost - problem with Django installation
Their (DreamHost) prices are ridiculous (ie low), and to keep them low, they can only spend time on things that have an identified market (they say this in their FAQs or KnowledgeBase or whatever its called). It's the main reason they don't provide PostGres. I guess FCGI for Django hasn't hit the big time for them... I've looked at Dreamhost (cheap, ridiculous storage and bandwidth, very much mass-market driven), TextDrive (not as cheap as DreamHost, but still good, ok storage and bandwidth, PostGres and other nice bits of software - but weird usage 'no webdevelopment'), A2 (from www.43folders.com) (cheap, low storage and bandwidth, PostGres or MySQL), Zettai (more expensive, unlimited domains, PostGreSQL and/or MySQL, Zope and Plone) and Gypsy hosting (same price as Zettai - $24.95/month, full Django, Postgres, Apache2, ok storage and bandwidth - currently not taking any more signups) I've not plonked down money for any of them yet. So you pays your money and you takes your choice... ;) Cheers, Tone

Re: Storing News articles - retaining some HTML tags
If your articles have HTML in them, you'll need to be careful that no 'dangerous' HTML is included (javascript is the most common).

Do I use @login_required to extend authentication?
I guess the title says it all - I want to use authentication methods that I'm used to from my Zope applications. This is mainly MySQL authentication, using a table consisting of; username, password, roles and domain. The authentication database is external and used by many other applications. However, I very much want to use additional authentication methods such as Shibboleth and LDAP (particularly Shibboleth). Should I use the login_required decorator from django.views.decorators.auth to do this? and if so, has anyone else done this - and have some code they can contribute? ;) Cheers, Tone
