models wierdness
I've got an app called page I've been working on. Pages can contain
text, graphics, or media and each have their own table which refer back
to page (ForeignKey). When I set up this model, only page_media has
the inlined SQL for the foreign key ("REFERENCES"), where as the others
do it with an ALTER TABLE syntax. This seems odd to me that almost the
identicle table definition is output differently. Should I be
concerned? Should each table have similar SQL?
Thanks,

advice on debugging ajax apps in django (possibly OT)
Hello, I'm a long-time python user who is new to django, javascript, and Mochikit. I'm very pleased with django so far but I'm having a bit of a quandry as I start to mix in javascript and Mochikit. One thing I like about django is that if I make an error in my python code it send me that great debug/traceback page. This works well if I submit a form as well. However, I've stared to get more adventurous with Mochikit and am trying to communicate with the server outside of a form. Of course, as I experiment, I make mistakes and I get back to my javascript console (thank you mochikit) a status=500 error and an xmlHttpRequest failed error. I know I made a mistake in my python code in views.py, and I know that django probably caught it and generated a traceback but I dont' know how to look at it. This has slowed down my coding cycle a great deal. Do others have tricks to get at this? Is it stored in the failed response on the javascript side? It seems if I could get access to it I could pop up a window and display it or log it somewhere. Many thanks for any help in advance. I will put a little code below to give an idea of what I'm doing. -chris === example === in my template I might have something like this in the

Re: Finding entries with multiple tags
agreed with Malcom on this one:you should be splitting the url string at the top (removing the last blank entry) to get the array of tags.from there you can just iterate over the tags array until you hit the end in a for loop.
then in that for loop, just call a filter on the queryset, using the current tag as the param in the filter call.(note, I am not near a django install at the moment, so this is all untested, ymmv)
tags = url.split("/")[:-1]
posts = Post.objects.all()for tag in tags: posts.filter(posttag = tag)return render_to_response("blog/tags.html", {'posts': posts})if the filter call isn't working correctly, that's another story :)

Can you explain the use case for this a bit more?
I am wondering what you want to do that cannot be done by just creating
the class instance at import time and then calling the method (since you
can now put direct function and method references in URLConf calls). For
example,
my_class = MyClass(...)
urlpatterns = patterns('',
('foo/$', my_class.some_method),
)
The ability to put function references (and not just strings) inside
patterns(...) is something that was only added recently (after 0.95), so
you will need to be running a recent subversion checkout to use this.
I'm not sure that creating the class instance at call time (instead of
import time) gains you a lot that you cannot do otherwise. But I'd be
interested to hear what I've overlooked.

Malcolm

This can't be done with the {% include %} tag, but it is the ideal
example of when a custom template tag is useful. After writing the tag,
including the tag as
{% ticker_data %}
wherever you needed it in your template (plus a "{% load ... %}" at the
top) is all you would need to do.
If your ticker data is best formatted via a small template fragment,
look at the inclusion_tag() shortcut for template tags ([1]). Otherwise,
you probably just need a simple_tag() template tag -- see [2] -- since
you are just returning a string from minimal (in fact, no) input
parameters.

If you're going to attach view and template behavior based on the
different relationship types as you add them, then I think it makes
sense to just have a separate attribute field on the Person model for
each relationship type.
class Person(models.Model):
...
contacts = models.ManyToManyField('self')
friends = models.ManyToManyField('self')
enemies = models.ManyToManyField('self')

Joe,
My bad. I misunderstood your question. I think the only way to do this
(in SQL) is with a subselect or with multiple joins to the same table,
neither of which are possible in the direct DB API. But you can use the
extra() method to get around some of the constraints.
To solve your specific problem, I started with the custom SQL:
select slug from blog_post
where id in (select post_id from blog_post_tags
where tag_id in ('programming', 'finance'))
This can be implemented in Django as:
>>> from danet.blog.models import Post, Tag
>>> Post.objects.all().extra(where=["blog_post.id in (select post_id from
>>> blog_post_tags where tag_id in ('programming', 'finance'))"])
[, , ]
>>>
So I've just copied the where-clause from the SQL (and explicitly
qualified the id column with 'blog_post.id').
Its debatable whether this is an improvement over direct SQL. You could
just as easily do
>>> from django.db import connection
>>> cursor = connection.cursor()
>>> cursor.execute("select post_id from blog_post_tags where tag_id in ('program
ming', 'finance')")
3L
>>> Post.objects.in_bulk([row[0] for row in cursor.fetchall()])
{16L: , 1L: , 6L:
}
>>>
In either case you've got about the same amount of custom SQL in your
Python code so its really a six-of-one situation.

Afterwards you can define a urls.py for each project.

I don't really get what you mean here, but in admin, for each user you have the "Staff Status" option in the "Permissions" section that designates whether the user can log into the admin site. So just uncheck it if you don't want users to access with the admin interface. Of course, in the worse of the cases you can simply "desinstall" the admin application, take it out of the urls.py or limit its access to given IPs only (this is Apache magic though).

Re: Creating new apps
Charles,I've always seen a Project as a Site. Although there are situations that that may not be true, for most of us, it probably is.I've seen an App as a grouping of functionality. Examples would be Blog, Forums, News, Gallery, etc.Good design practices should keep as much internal within each App as possible, so you can use the app with other projects. That is why you would have a urls.py and a views.py in each App directory.Each App is linked into the main project by: INSTALLED_APPS in settings.py and configuring a base url (eg. /blog ) that then references the App's urls.py.For authentication, you can use the contrib.auth. They don't have access to the admin unless they are a member of staff.Hope that helps,CoreyOn Aug 29, 2006, at 12:16 PM, charles sibbald wrote:Hi Guillermo,Thanks for the help.I have been on your SVN, but how do i tell Django that each little app has its own urls.py? is putting it in the directory enough to automatically let django know that each little app has its own urls.py?Also for authenticating users, do i use django.contrib.auth, which is the same as the admin system.I dont want users to have access to my backend system.RegardsCharles- Original Message From: Guillermo Fernandez Castellanos <[EMAIL PROTECTED]>To: django-users@googlegroups.comSent: Tuesday, August 29, 2006 3:47:51 PMSubject: Re: Creating new appsHi,I did my own homepage (www.haruki.eu) where I have several"applications" done together.As I understood after asking in the list and looking at severalproject svn trees, the 2nd way seems to be prefered for a sizableapplication.

Nothing right now. Currently the admin interface doesn't use any AJAX, but it has been under discussion for a while to implement it. If you did wish to use it, you could probably modify the admin interface fairly easily to implement it (w/o changing the actual django.contrib.admin) package. There are other threads and articles on the wiki about doing this, but feel free to ask if they don't help.

How to handle person to person relationships
How code the relationship like
"a person has many friends"
code so far.
class Person(models.Model):
full_name = models.CharField(maxlength=100)
nick_name = models.CharField(maxlength=20)
about = models.TextField(blank=True)
sex = models.CharField(maxlength=1, choices=SEXES)
# contact is also a person object so it is a reference to same
person
# more study needs to be done on how to add attributes to
ManyToMany relationship in Django
# e.g. we may need to define whether a contact is my friend etc.
# creating a separate class for Contact may not be the a good
solution, since a Contact is also a Person
contacts = models.ManyToManyField('self')
Or like this
class PersonRelation(models.Model):
person = models.ForeignKey(Person)
relations = models.ManyToManyField(Person, related_name =
'friends')
type = models.IntegerField(choices=FRIEND_TYPES)
group = models.IntegerField(choices=GROUP_TYPES)
please highlight pros and cons.

With ManyToMany relationships, you have to think of chasing the
relationship backwards. Instead of finding the posts with a given tag,
start with the tag and find the related posts:
>>> from danet.blog.models import Post, Tag
>>> t = Tag.objects.get(pk='programming')
>>> t.post_set.all()
[, ]
>>>
My models look like this:
class Tag:
...
class Post:
tags = models.ManyToManyField(Tag)
...
Thus Post.tags is the set of tags for a given post and the reverse
relationship is created automatically as Tag.post_set (you can override
this with the 'related_name' arg to something like 'posts' if you
like).

It wouldn't be Django redirecting, it would be mod_python. And yes, having to get emails while you develop is silly. That's why I recommend using the dev server. Then you see the errors, immediately, right on screen, without having to run 'tail' on an error log or anything. When you're 100% happy with how it runs with the dev server, start testing with Apache.

My recommendation is to do all your main development with the Django server. When you're completely happy with how it runs, start testing with Apache.

Re: viewing generated SQL without running the query

You can just do the same construction that's done in
django/db/models/query.py:
>>> from danet.blog.models import Post, Tag
>>> qs = Tag.objects.filter(title__icontains='a', description__icontains='n')
>>> cols, sql, args = qs._get_sql_clause()
>>> "SELECT %s %s" % (', '.join(cols), sql % tuple(args))
'SELECT `blog_tag`.`slug`, `blog_tag`.`title`, `blog_tag`.`description`
FROM `b
log_tag` WHERE (`blog_tag`.`description` LIKE %n% AND
`blog_tag`.`title` LIKE %a
%) ORDER BY `blog_tag`.`title` ASC'
>>>
There's some special handling for DISTINCT if you look at
django.db.models.query.iterator(), but the snippet above is close
enough. After a while you get used to just looking at the list from
_get_sql_clause() directly and can just add the "SELECT" and replace
the args in your head.

Additional Functionality to Admin Interface
Hi there I'm quite new to Django, and I couldn't find anything in the documentation. I want to develop a gallery system in Django, so if I add a new picture, I'm uploading it (the field is a ImageField). But I don't want to set the height and witdh, I just want to upload the image file (in the original size) and then generate some thumbnails and also save them. How can I do this? I think that I have to call another function from within the administration area when I create another Image --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

threadlocals with limit_choices_to in models
Hi,
I'm using the threadlocals hack
(http://code.djangoproject.com/wiki/CookBookThreadlocalsAndUser) in my
model to filter machines by group. But it's not stable at all. And most
of the time the filter return nothing because the usergroup is empty.
Here's a piece of my code :
usergroup = threadlocals.get_current_user().groups.all()[0]
machine = models.ForeignKey(Machine, limit_choices_to =
{'group':usergroup})
On the admin interface the list is empty, but after some browser
refreshing it comes, and then goes away. It's not stable at all.
Some help please? I'm facing this problem for weeks now in my
project!!! :|

Re: Multiple File Upload???
Ok, the problem then is, that my model has just a single entity called picture. What I'm trying to do is asociate multiple image files to multiple `descriptions'. I'm doing this by a intermedaite table: #Images to be used in descriptions class Image(models.Model): altText = models.CharField(maxlength = 128, null = True, blank = True) picture = models.ImageField(upload_to='img/%Y/%m') ... # Replaces the Many-to-Many Relationship class ImageInDescription(models.Model): description = models.ForeignKey(Description, edit_inline=models.TABULAR, num_in_admin=3) image = models.ForeignKey(Image, core = True) ... #Descriptions class Description(models.Model): lang = models.ForeignKey(Lang) description = models.TextField(null = True, blank = True) ... That's it. So as you can see in the first class, `Image' is itself an element to be uploaded. I guess I could add more ImageFields to the model but that would't make sense, would it? Isn't there a way to upload as many files as i want to (much like gmail handles attatchments) and then associating them to the descriptions?
