strange admin interface issues runserver vs. apache
Hi All -- Sorry if this is a newbie faux pas. I am having an issue with viewing the adding admin interfaces I created for a number of my models. Everything appears fine when accessing the admin site using the development server, but when I try to view my changes running through Apache, none of the model interfaces show up on the admin home page.

extracting field information from models
Hello,
I would like to loop through the fields in my model and print the names
(verbose_name) and value of the fields. I've been hacking at it for
sometime but can't figure it out. I had some help from Magus on IRC
but still can't find solution.
See: http://simon.bofh.ms/logger/django/2006/12/13/19/57/
Q: Why not just type it out in the template, so you actually get a
decent display?
A: I'm lazy, and the old problem of "there's lots of fields", like 60
or so.
Here's what I'm trying in my view. I want a rudimentary display of an
Application, the object is app. In the template I would just loop over
app_fields.
app_fields = []
for f in app._meta.fields:
app_fields.append(
{
'label':f.verbose_name,
'value':f.__getattribute__(f._meta.fields[0].attname)
}
)
app_fields.append(
{
'label':f.verbose_name,
'value':f.__getattribute__(f.id)
}
)
return render_to_response( 'workshops/application_detail.html',
{
'app': app,
'app_fields': app_fields,
}, context_instance=RequestContext(request),
)
I keep running into problems with special fields like AutoField,
ForeignKey and BooleanField.
Like:
'BooleanField' object has no attribute 'id' or
'BooleanField' object has no attribute '_meta'.
If you have comments or advice, much appreciated.

Using django's test facility
I am having trouble using django's test facility.
I have written a unit test (copied from the example on the website):
# Issue a GET request
response = self.client.get('/archive/')
# Check that the respose is 200 OK
self.failUnlessEqual(response.status_code, 200)
This test fails with a status code 404
The full code is below my sig.
However, this page does render for me, and when I perform the same
command from the shell, the response code is 200 as expected.
>>> from django.test.client import Client
>>> client = Client()
>>> response = client.get('/archive/')
>>> response.status_code
200
>>>
What am I doing wrong?
Thanks,
Ryan Ginstrom

from django.test.client import Client

# Every test needs a client

You may want to read this thread from the developers list, which goes through some of how this will work (and contains references to earlier threads discussing the full API): http://groups.google.com/group/django-developers/browse_thread/thread/7d40ad373ebfa912/ > I'll look into how to do such a thing, but, being new to both python > and django, would like to know first if such a thing is feasible. Not at the moment. Representing class hierarchies robustly and efficiently in a relational database (which isn't designed for hierarchical relations) is tricky at best, which I think is one of the reasons behind the delay in getting it working "properly". Your best bet right now is a one-to-one relationship, which exposes an API not dissimilar from the one Malcolm has described -- querying against a particular model class only returns instances of that model class, but fields from parent or child classes will be accessible if you explicitly ask for them from a particular instance (for example, if you have a class Thing and a class Animal related to it, each Animal will have a 'thing' attribute which will query the fields of the related Thing object). -- "May the forces of evil become confused on the way to your house." -- George Carlin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Paths in Python 2.5
Thanks but I don't have, and don't want an irc client, so I'll just struggle along and try not to ask stupid questions. My problem is that Python 2.5 and sqlite3 seems to be a buggy combination.

I have had to edit "C:\Python25\lib\site-packages\django-0.95-py2.5.egg\django\db\backends\s qlite3\base.py" for instance, to refer to sqlite3 instead of pysqlite.

The only big changes that affect the mainline django code are in django.core.management. I'm using my patches, so that's been tested through 3 schema updates in production. As previously mentioned -there are those 2 remaining bugs in the schema-evo code, but they're not show stoppers for me. I see no reason why people need to use the latest trunk to test beta quality features. That just makes no sense - if you need beta features - use a branch, or apply my patch to your own copy of trunk. Is there a problem that I'm not seeing? I'm quite sure that all the code that my patch modifies hasn't been touched in over a month, so it should apply cleanly to trunk. vic On 12/14/06, Todd O'Bryan <[EMAIL PROTECTED]> wrote: > > I know the company line on the SOC Schema Evolution code is that it will > be integrated into the trunk after enough people have tested it, but I > think this creates a chicken and egg problem.

Python's path (which is the list included in sys.path) is totally separate from the window path. You probably want to associate the .py file extension with c:\python25\python.exe so that you can directly run django-admin.py (using the windows path). >From there, you'll want to also make sure that c:\django is included in your Python path. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Re: Schema Evolution code
I know the company line on the SOC Schema Evolution code is that it will be integrated into the trunk after enough people have tested it, but I think this creates a chicken and egg problem. People aren't going to use it until it's in trunk and it won't be in trunk until enough people test it. Does it impact normal use without using schema evolution? In other words, could it be integrated into trunk with the proviso that "The Schema Evolution feature should be considered beta. If you use this feature, please test the results carefully and report any bugs you find. If you don't use Schema Evolution, you shouldn't be affected." I'd really like to try it, but I don't have time to keep up to date with two branches.

Re: Tips/advice on model and application design?
It really just depends on how you're accessing the data. I tend to optimize for developer simplicity first, and then go in and adjust/split/modify code as needed when performance isn't where it needs to be for whatever application I'm working with. The case where multiple models might work a little better than fewer, larger models is where you find yourself with either a lot of sparse data (some significant portion of the model being null or empty), or the need to consistently edit just a small portion of the data (one bit of metadata gets updated a lot, the rest of the information doesn't). But practically, I'd recommend building your app so that it makes the most sense to you, and then seeing how the performance rolls out. Worrying about "that might make the performance bad" from the very beginning isn't usually a good idea. -joe On 12/14/06, Austin Govella <[EMAIL PROTECTED]> wrote: > > > I'm new to Django, so I was looking for some advice on good model and > app design and on how that affects performance. > > My first app has nine models, and after working with it for a bit, it > seems like it's actually two apps: one for meta data and another for > content management. > > Are there any rules of thumb for when you should separate out some > functionality into its own app?

Re: Would Django be a good framework for developing and engineering/science application
Jay, Thank you for your comments. At least it looks like I will be able to use Django.

Under relational database theory, nulls are not less than or greater than any value, including other nulls. Because of this, you should never count on where a particular database puts those values. The page you quoted explains the allowances that database authors have made to work around the problem. The page didn't even mention sqlite, which follows mysql's convention. I would say this is something that Django should stay away from, too many differences, even more when you include aggregates such as min() and max(). For example in Postgres, min() and max() ignore nulls in columns unless all column values are null, so this behavior is not consistent with its column sorting routines. I think If you want minimum or maximum values in your tables, they should be explicitly coded.

Somewhat awkward ImageField usage
I have this model:
class Photo(Model):
title = CharField(
maxlength = 80,
)
description = TextField()
photo = ImageField(
upload_to = "photos/%Y/%m/%d",
height_field = "H",
width_field = "W",
)
W = PositiveSmallIntegerField("Width", null=True, editable=False)
H = PositiveSmallIntegerField("Height", null=True, editable=False)
W and H are both set to null=True, because I found that if you used
the default of null=False, and created the columns as NOT NULL, you'd
get a database error upon the initial add because the columns were
being set to NULL. However, if you set them to null=True so that they
can contain NULL, they *do* get the dimensions saved to them. There
seems to be an intermediate step where the row is first inserted with
NULLs for those fields and then it is updated. The workaround is to
null=True and editable=False so that the user can't futz with these
values, but it would be better if null=False worked.
The docs (trunk) currently say about ImageField's height_field and
width_field that the referenced fields are auto-populated "each time a
model instance is saved" but that seems to not be literally true.
If this seems bug-worthy, let me know.

OneToOneField and edit_inline
Hello,
i'm having some problems with the OneToOneField. I have a content app with a
class Content that i want to use as base class in several other classes (like
Project in the below example):
class Content(models.Model):
title = models.CharField('Title', maxlength=255, core=True)
body = models.TextField('Body text')
class Project(models.Model):
content = models.OneToOneField(Content, edit_inline=models.TABULAR,
num_in_admin=1, core=True, related_name='project_content')
subtitle = models.CharField('Subtitle', maxlength=255)
class Admin:
pass
Now when i try to add a project through the admin interface, i don't get the
Content fields inlined, but only a empty input dropdown. Am i missing
something obvious?
I'm using Django-0.95.
Best Regards,
Dirk Eschler

In-house intranet app for an engineering company. We had some in-house Python tools that were used pretty heavily, but each user had to run their own version of it, and we couldn't place any controls on how it was used. So, I created a Django app. Engineers would log in, fill in the necessary info into the forms, and hit Submit. Processing would fire stuff off to another dedicated server, a process that could take up to a minute. Eventually, it'd finish, and send the data back to the Django app, presenting the user with the final results (done with a little AJAX). Certain admins could then log in and track what different people had done, as well as grant and remove permissions for individual users to perform certain actions. So essentially, it was a big Django app wrapped around tens of thousands of lines of Python code that was previously used in the end-user tool. Worked like a charm, everyone seemed pretty happy with the system. Hope that helps. I know I didn't offer too much in the way of details, but essentially, it sounds like I did what you plan on doing. The only problem I ran into was getting the AJAX stuff going, but that's only because this was both my first ever Django app, and my first time trying out AJAX. I simply used the AJAX so the "Submit" button would immediately bring the engineer to a new page, and I could keep them up to date on the status as the separate server did its processing.

Would Django be a good framework for developing and engineering/science application
I would appreaciate any comments about if Django is a good framework of developing an application like is described below. If it is a good framework for this I would appreciate pointers to applicable documentation or examples. In the near future I will be developing an application that will be used as a tool for doing the electrical engineering for making electrical power transformers. Individuals from other parts of the company will have to access parts but not all of system. Anyway here are the details 1. An electrical engineer will log into the system, access one of several design programs and after completing a few forms submit for the program to perform iterations. Output will be saved to a database and portions of the output will be published to other parts of the company. I have libraries in python for doing most of the engineering part of this work right now. It could take several minutes for each transformer design to run making the iterations. 2. Managers will login the system to run reports. Few items if any can be changed by management but they will do a number of reports. Django's CRUD system looks very promising to me for this part. 3. Purchasing agents will update prices for components and get reports of requirements for recently released jobs. 4. Authentication by person and role will be very important. 5. The deployment will be on an intranet initially but web access in the future would be a great asset thus my interest in using a web framework. Most of the examples I have seen for Django seem to focus on custom CMS type applications. Atleast the engineering function described above is more of a servlet (although a big one) type application.

Django 0.95 is reasonably old now, and by default, it tries to download setuptools 0.6c1, for Python2.5. However, there is no 0.6c1 for Python2.5, the only one they have available is 0.6c3. So here's the easiest thing to try: In the Django 0.95 folder, there should be a file called ez_setup.py. In it, near the top, is the following line: DEFAULT_VERSION = "0.6c1" Change that to DEFAULT_VERSION = "0.6c3" And give the install a try again. If that doesn't work, then try installing setuptools separately, by itself. In the current SVN version of Django, the setuptools stuff has been removed (at least, it was removed at one point, don't know if that's true anymore). So this won't be a problem in the future. You just happened to be one of the few people running Python2.5 and Django 0.95. Most people running 2.5 are probably running Django out of SVN, where this isn't an issue.

Adding a foreign key to list_display makes Admin hang
Not sure how to trouble-shoot this. (And I could've sowrn it worked yesterday.) When I add a column that's a foreign key to list_display, admin hangs. The change list just never loads. (The add/edit page loads and saves just fine.) I've tried deleting the database tables for the app and reinstalling the models, but I get the same (nothing) happens.

Re: ImageField: Unique with number, not underscore?
Yup, save() will be called whenever a model is written to the database, including through a manipulator (again, afaik) self.name is just for example purposes. You need to change the name of the file in the ImageField or FileField object within your model. But yes, if you do this from an overloaded save() method it should change the name of the actual file (which will be written when the parent class save() method is called). Of course the only way to be sure is to try it and see. I actually have to implement something like this in the next few days; if I get something working I'll post the snippet.

Filtering firstof vars in templates
Hi, i'm testing the firstof tag in templates, but i want to filter some
vars. In this case, the vars are dates, and usually y use {{
week|date:"W" }} to get the week number (week is a full date), but i
also want to get the same with {{ day|date:"W" }} (also a full date).
It,of course, can be done with some if, but firstof seems to be my best
friend here ;). I've tried with {% firstof week|date:"W" day|date:"W"
%} and it doesn't work (at least with last cvs version), and wrapping
it with {% filter date:"W" %} seems to not work because it handle the
vars as text, not a date.
I've googled a lot in this list and read the docs in the webpage, but i
have not find something about it. If it's not possible, it could be a
good feature request for the next version ;), and if is possible,
someone could point me how do it? thanks. :)

How to hack admin interface?...and should I?
Hi djangees, I'm a TurboGears user, I like CherryPy, Kid and so. I like Django as well and tried the tutorials. What I like about Django is (obviously) the auto-generated admin interface. However, what I need to know is how easy/difficult/deprecated/encouraged is to hack the auto-generated admin interface. I'm doing this app, where our customers login and vote for features that we plan to implement in our services. And besides CRUD, I need to enable my boss to login and view a whole bunch of stats about who voted for what and how is that particular guy important for us etc... So, my question is, how easy would it be to "add a page" to admin, that would have the same auth restrictions, same GUI but would only display bars and graphs generated from the DB? Or would you write an admin section from scratch in that case? Right now I'm writing everything on my own in TurboGears. It's not bad, since auth/auth management is pretty intuitive in TG, but it's kinda boring...

Re: Re: Schema Evolution code
If anyone wants to poke at our schema evolution code you should be able to apply this patch attached. It's mostly working. The bugs I know about are: 1) M2M fields can't be repointed at new tables properly 2) there's some weird quirk with modifying null and db_index at the same time. i have to run the sqlevolve command twice to get the column to get altered and to have the index added. The patch also fixes a couple problems I discovered in Django's existing syncdb command and the way it handles unique and db_index arguments. Those bugs were: 1) syncdb sometimes seems to 'miss' setting up foreign key constraints between applications. 2) foreign key constraints were specified inconsistently. Sometimes a 'REFERENCES' clause was added to the CREATE TABLE and sometimes a CREATE CONSTRAINT was used. This caused problems with figuring out the names of the constraints I needed to remove. 3) indexes were created multiple times sometimes in cases where a primary key was set. 4) indexes were *not* created for unique columns. technically not a bug, but i can't see why you wouldn't want an index. For small tables, the cost of the inserting a record against an index is small - it's a small table and there just aren't that many inserts. For large tables, the lack of an index means you're going to incur a table scan. Again - this code is ugly and needs to be cleaned up a lot, but it's working well enough for us against postgresql+psycopg2. It doesn't work on any other backend. Test cases are in the tests/evolvedb/runtests.py script. You'll need to symlink from tests/evolvedbtests/db_settings/settings.py.postgresql script to tests/evolvedbtests/backend_settings.py. All the existing django tests seem to pass with my patches applied. There's no documentation but there's ~40 odd tests checked into that evolvedb tests directory. Unfortunately, I'm pressed for time for the forseeable future and I don't think I'll be able to spend a lot more time working on this code. vic On 12/14/06, Russell Keith-Magee <[EMAIL PROTECTED]> wrote: > > On 12/13/06, Steve Hutton <[EMAIL PROTECTED]> wrote: > > > Does it have a realistic chance of being accepted into core if it's found > > to be bug free?

Tips/advice on model and application design?
I'm new to Django, so I was looking for some advice on good model and app design and on how that affects performance. My first app has nine models, and after working with it for a bit, it seems like it's actually two apps: one for meta data and another for content management. Are there any rules of thumb for when you should separate out some functionality into its own app? Is there a certain number of models that would suggest you probably have more than one app? Is there any impact on Django's performance? I.e. is an app with four models faster than an app with 20? If I'm importing models from one app into another, is that faster/slower than just having all the models in one app?

Re: Help with get absolute url
This isn't working for you?
{% for organisation in object.organisation_set.all %}
{{
organisation.org_name }}
{% endfor %}
If the name works, but not get_absolute_url I'd say you have something
wrong with your model. Open a shell and play with you model to make
sure everything is working right.

The discussion was started by Jacob, and other committers (Luke and Malcolm) weighed in at the time, along with many other interested onlookers. The resulting design is on the wiki. Assuming that the implementation matches the proposal, I would say there is a realistic chance of it getting accepted into core.

Any thoughts, > comments, criticisms? Obviously, it would be nice to be able to support this sort of thing without having to resort to custom SQL and custom managers, but with Django as-is, this looks like a reasonable enough solution to the problem. There was some recent talk about adding aggregate clauses to the Django query language. With richer aggregates, 'orphan finding' (amongst many other things) would be much easier; however, discussion didn't get much further than the proposal phase.

Yes and No. Django does have the ability to do a sort of model inheritance, using OneToOneFields. This establishes a 1-1 relationship between a base class and a child class. For example: class Base(Model): name = CharField() class Article(Model): base = OneToOneField(MyBase) length = IntegerField() class Author(Model): base = OneToOneField(MyBase) age = IntegerField() In this case, each Article is required to reference a single Base instance (likewise for Author). An article instance can ask for base.name to get the name of the article; author.base.name will give the name of the author. Obviously, this is less than ideal, and there are a few gotchas - for example, you have to manually create the base class instances. However, it does work. There is a work-in-progress to add a more formal inheritance structure to Django - search the developers archives and the wiki for a detailed discussion of the form this inheritance will take. This work is being performed by Malcolm Treddinick. Last time I heard from him, he was close, but not quite finished, and there were a few issues in other areas holding him up. However, he's been a bit quiet of late. Malcolm? You still out there? How goes the struggle?

You could use extra() to add an expression column and then order by
that. Something like:
>>> s = Strategy.objects.all().extra(select={'mycol': 'case when name is null
>>> then 1 else 0 end'}).order_by('mycol', 'name')
This adds a new column to the select using the case expression and
aliased to 'mycol' which you can then reference in the order_by()
clause. By making null's have a value of 1, it forces them to be sorted
below non-nulls.

Re: Help with get absolute url
In other words, why can't I simply put
{{organisation.get_absolute_url}}
to return the organisation's detail page?
Surely the whole point of the get_absolute_url is to be able to call an
object from wherever?
So what would I put in the model and/or urls.py to be able to do this?
At the moment I just
have:
def get_absolute_url(self):
return self.slug
for the Organisation model.?
Can't I just define this further?

null ordering in mysql
Problem: I order dates and null values in ascending order under MySQL. To my surprise, null values are listed first, then actual dates.
