newforms confirmation page, displaying input data
I am trying to display the data input using a newform on a new page
after it is verified. I am looking at the 'Complex template output'
code given in the newforms documentation. However I do not want to
display the input field with data (what '{{ field }}') displays but
rather just the data. Does anyone know how I might accomplish this?
Here is a sample of the code I am using:
{% for field in form %}
{{ field.label_tag }}
{{ field }} {# replace field with something that only
displays the field data #}
{% if field.help_text %}{{ field.help_text }}{% endif %}
{% if field.errors %}{{ field.errors }}{% endif %}
{% endfor %}

Even in 'prefork' mode of Apache, there are multiple processes handling requests and so concurrent requests is not a problem. The problem with prefork though is that you can end up with lots of process, all consuming the maximum your Django application will use. For memory constrained VPS systems, using 'worker' MPM is a better choice as you cut down on the number of Apache child processes and therefore memory, with concurrency then coming from multithreading, but also from fact that multiple processes still may also be running. You might have a read of: http://code.google.com/p/modwsgi/wiki/ProcessesAndThreading which talks about the different process/threading models that Apache provides and how mod_wsgi makes use of them and extends on them. In respective of thread safety of Django, where does it say it is 'not officially thread safe'. I know that it is implied through fact they suggest prefork when using mod_python, but they also don't say to avoid mod_python on Windows, which is multithread, plus FASTCGI examples give examples using multithreading. So, there is actually conflicting information on the issue. As explained in: http://code.google.com/p/modwsgi/wiki/IntegrationWithDjango the situation seems to be that there are no known current issues with Django itself in respect of multithreading. Thus, any multithread problems are more likely to come from the application built by a user using Django. So, it is just a matter of testing your application so you are satisfied that there isn't a problem. > I looked at mod_wsgi and decided to try fastcgi since the Django docs > explicitly support it. But, given my problems perhaps I'll try > mod_wsgi next. That there is nothing in Django documentation about mod_wsgi is more to do with no one offering up anything to add which mentions it. The Django documentation on mod_wsgi site is reasonably comprehensive and maybe even a link to that would be a good start. I haven't offered anything up myself for the Django site as believe that it has to be the Django developers/community that first need to work out whether they see it as a viable option and when they are happy add a link to it. FWIW, people are using mod_wsgi quite happily with Django. I know of a couple of notable Django sites which are delaying looking at moving until mod_wsgi 2.0 is released as that will be the first version which allows Python code to be used to implement Apache HTTP authentication provider. For what those sites do, having that feature is critical and they can't move away from mod_python until mod_wsgi provides an equivalent mechanism.

I'm going to follow up on my own post with some additional
information.
In db.models.query.get_where_clause, the __year lookup type is treated
like a range using 'between':
elif lookup_type in ('range', 'year'): # could remove 'year' from
here.
return '%s BETWEEN %%s AND %%s' % field_sql
Whereas __month and __day use sql functions to extract the relevant
column:
elif lookup_type in ('month', 'day'): # could add 'year' here.
return "%s = %%s" %
connection.ops.date_extract_sql(lookup_type, field_sql)
The %%s portion of those strings are filled in by
db.models.fields.Field.get_db_prep_lookup(self, lookup_type, value).
__year lookups return the following:
elif lookup_type == 'year':
try:
value = int(value)
except ValueError:
raise ValueError("The __year lookup type requires an
integer argument")
return ['%s-01-01 00:00:00' % value, '%s-12-31
23:59:59.99' % value]
#return ['%s' % value] # could treat year as a single
value.
This matches the between clause we saw earlier.
__month and __day return:
if lookup_type in ('exact', 'regex', 'iregex', 'gt', 'gte',
'lt', 'lte', 'month', 'day', 'search'):
return [value]
This matches the extract function we saw earlier.
So understanding how all this works, my question is why are __year
lookups treated this way?
I changed the django code to treat __year the same as __month and
__day (as commented above) and fixed the issue of the first day of
January being missing from the event_from_date__year=2008 query I
referenced in my first post, so it's at least functional this way (not
necessarily correct).
I'm sure I'm missing something, so if someone knows why __year queries
are treated as betweens rather than sql function extractions I'd like
to know. :-)

Doug Van Horn

Probably an easier question to answer if we could see the models
involved (and perhaps an English description of what you are wanting to
achieve). My gut feeling is that this is either as simple as you get or
else it should be possible to fold the exclude directly into the "cards"
queryset without having to do an explicit extra query. Which alternative
is possible depends on your model relationships.

Re: Installation - symlink vs. python setup.py install
On 10.5 with a virgin Python 2.5 installation there is no: /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/ site-packages If you have it then something has wrongly created it and you probably should delete the whole directory in case it causes problems. The Python 2.3 installation on 10.5 still has the site-packages in the long path location, but as I said, it is a symlink to /Library/Python/ 2.3/... BTW, with all the problems you are having, you might want to look at mod_wsgi 2.0 instead and use its support for easily pointing at Python virtual environments created using virtualenv. This way you could have different virtual environments for different versions of Django and how applications using the different versions in different daemon processes using mod_wsgi daemon mode. :-) Graham On Dec 6, 11:14 am, Graham Dumpleton <[EMAIL PROTECTED]> wrote: > Okay, I had a part brain fade there.

Karen, The ticket says, "If flatpages and DEBUG=False and 404.html doesn't exist it throws the error".

Strange FastCGI problems
I've been using Django for the past few months and had great results with Apache and mod_python. However, I'd like to try and reduce the amount of memory that is used by having multiple Apache's each with their own copy of my application. I decided to try mod_fastcgi in Apache and Django's FastCGI server capability. While running with FastCGI, every now and then I get a random exception 'RegexURLResolver' object has no attribute 'get_and_delete_messages'. In months of running my application with mod_python I've never seen this. I have another web app running under mod_python and it works fine every time with FastCGI. I'm using Apache 2.2.3, Centos, python 2.4.3, Django from SVN from about early October 2007, flup 1.0, and mod_fastcgi 2.4.6. Can anyone offer any pointers into what might be going wrong? Thanks!

If you're using CACHE_MIDDLEWARE_ANONYMOUS_ONLY you need a different middleware ordering, as the error message says. That setting is a real hack and I'd love to implement it in a better way some day. At the moment, though, where you place the cache middleware depends on whether you're using that setting or not.

Re: Order By Calculated Value??
Hi Tane,
[untested with Many2Many, but should work, it works for ForeignKeys]
In your Entry save() method call the save method of each of your related
categories after you do your super().save()
{{{
class Entry(models.Model):
...
def save(self):
if not self.slug:
self.slug = slugify(self.title)
super(Entry, self).save()
for category in self.categories:
category.save()
...
}}}
Then in the save method for your Category object you need to calculate
the number of entries in that category before you call super().save()
{{{
class Category(models.Model):
...
def save(self):
if not self.slug:
self.slug = slugify(self.name)
self.num_entries = self.entry_set.count()
super(Category, self).save()
...
}}}
Hope that helps, or at least gives you a pointer.
Regards
Darryl

Should this be filed as a bug? You need to provide a 404.html independent of whether you are using flatpages. Users can enter whatever they like in a browser address bar, your site should respond with a sensible error message when they try to get to a page that doesn't exist. http://code.djangoproject.com/ticket/3335 raised the issue of flatpages needing 404.html and was closed wontfix, so I'd say the current behavior is intended.

Re: Installation - symlink vs. python setup.py install
Okay, I had a part brain fade there. Was confusing /Library/Frameworks/ Python with /Library/Python. The /Library/Frameworks/Python is what MacPorts uses. Also looks like Python 2.5 on Mac OS X 10.5 sets up sys.path differently, ie., uses shorter /Library/Python/2.5/sites-packages instead of longer path out of /System/Library/Frameworks/Python. On Mac OS X 10.4 and Python 2.3 the long path version is just a symlink to the short path version. 8 lrwxr-xr-x 1 root wheel 56 Jul 13 2006 site-packages - > ../../../../../../../../Library/Python/2.3/site-packages Ie., they should effectively be the same directory, yet your comment about partial Django in long path suggests they aren't, or what you are symlinking to with the django link isn't correct in the first place. I have 10.5 on a firewire drive here so I'll try and boot it up and see how it links the two directories if it does.

For the record:
There is a FilterExpression class in django.template that does exactly
what I need. So for the tag implementation, instead of:
===
from django.template import resolve_variable
@register.tag
def mytag(parser, token):
tag_name, message = token.split_contents()
[...]
return MytagNode(message)
class MytagNode(template.Node):
[...]
def render(self, context):
actual_message = resolve_variable(self.message, context)
[...]
===
I do it like this:
===
from django.template import FilterExpression
@register.tag
def mytag(parser, token):
[...]
filter_expression = FilterExpression(message, parser)
return MytagNode(filter_expression)
class MytagNode(template.Node):
[...]
def render(self, context):
actual_message = self.filter_expression.resolve(context)
[...]
===
The filter_expression.resolve(context) runs all the filters attached to
the variable and things work as expected. The 'parser' argument even
makes it aware of custom filters loaded through {% load ... %} tags.
Lesson learned, note taken.

I've read the documentation. I admit to being more than a little
deficient with databases. Can anybody suggest a better way?
if len(study) < 20:
exclude = user.study_set.filter(stack=stack).values('card')
cards = stack.card_set.exclude(id__in=[i.get('card') for i in
exclude])[:20-len(study)]

"Between" bug when using SQLite?
I'm running into a funny issue when testing with SQLite3 (Python 2.5).
I have a model with the following (simplified):
class Event(models.Model):
event_title = models.CharField()
event_from_date = models.DateField()
I create an event on 2008-01-01 (January 1st) and on 2008-01-02
(January 2nd).
I run the following in the shell:

Could it be that the 'year' predicate is missing the 'django_extract'
function?
Thanks for any help...

Thanks Jonathan, the articles referenced really help clarify things. I have the code in the correct directories now, and all working. I had the blinders on with reference to my individual project directory. This should help avoid duplication when referencing these from multiple "projects" once I get them going. I want to do a couple of blog-type sites, and I only have to checkout/update the code once for each.

The tagging application needs to be on your PYTHONPATH (i.e. the 'tagging' folder should be sitting on the same level as your 'myproject' directory or in any other directory which is on your PYTHONPATH), that's why the docs specify that you need to check the 'tagging' folder out to somewhere on your PYTHONPATH and have 'tagging' in your INSTALLED_APPS. Another option could be to also add your 'myproject' directory to the PYTHONPATH, so when any application tries to import from the 'tagging' module, it will be found. If you're finding the whole application/project thing confusing, these articles may be useful :) http://www.pointy-stick.com/blog/2007/11/09/django-tip-developing-without-projects/ http://www.b-list.org/weblog/2007/nov/09/projects/ Regards, Jonathan. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Unhandled Exception on new server (Lighttpd + FastCGI)
Hello, I was recently charged with installing a new development server at work, and I'm having some trouble getting Django to work as FastCGI under Lighttpd. The new server is setup identical to the old server, except for some hardware upgrades and we moved from Ubuntu Dapper to Ubuntu Gutsy. Lighttpd starts with no problems, and so does the bash script which starts the fastcgi daemon, but when I visit the URL (ccsx.dev.ccsx.com) in my browser, I get an "Unhandled Exception" error. My startup script can be found here: http://dpaste.com/26896/ (Got it from the docs, and it works well on the old server) My lighttpd config can be found here: http://dpaste.com/26897/ (Same as on the old server) This is what's in the lighttpd error log: http://dpaste.com/26888/ (Could this be an issue with flup?) At first, given what's in the log, I thought it was a flup problem. I had originally installed flup via apt, so I uninstalled and reinstalled it (again, via apt) but got the same error. So I uninstalled it and reinstalled it using easy_install, and am still getting the same error. If I manually run "python manage.py runserver 0.0.0.0:8000" I can visit ccsx.dev.ccsx.com:8000 and it works (aside from the /media/ folder, as Django isn't setup to serve that.) By the way, I'm running the latest svn release of Django (currently 6897) Anyone know what might be going on? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Issues trying to Caching a View
Alright... still haven't figured it out. The Vary: Cookie header gets added because I am using user authentication stuff and the view depends on the user. But I still want the browser to cache the file. I was thinking of using @cache_control(private=True, max_age=37000) in order to deal with the user specific factor. Instead, with Vary: Cookie, the browser goes back to the server and grabs the file again. Which is not what I want. Any help would be appreciated.

about nesh.thumbnails
hi folks, I'm using the django app "nesh.thumbnails" for my thumbnails
stuff and I got two problems:
1- how can I generate thumbnails for the admin interface using this
app, I try this approach:
def admin_thumbnail(self):
if self.image:
return '{%% load nesh.thumbnails %%} ' %
(self.get_image_url(),)
return ''
admin_thumbnail.short_description = 'Thumbnail'
admin_thumbnail.allow_tags = True
but it doesn't work, then I try this:
def admin_thumbnail(self):
from nesh.thumbnails import *
if self.image:
make_admin_thumbnails(self)
return '' % make_thumbnail(self.get_image_url(), 120)
admin_thumbnail.short_description = 'Thumbnail'
admin_thumbnail.allow_tags = True
it works but this approach got a little problem, when I remove the
object from the database, it doesn't delete the admin thumbnails.
because the way it rename the thumbnails when you set auto_rename =
True. It rename the thumbnails to --. but this is done in the pre_save signal so, when you are
going to save an object the first time, it doesn't have the primary
key number set yet and this had two implications:
1- If there is any object image in the path you are going to save this
image, this new image overwrite the old image.
2- due to the first immplication, if you delete and object with an
image, it will delete the image too, but this image is shared across
all objects added after the object being deleted. This is true for
objects of the same type (model).
2- Is there any way to add templates tags, filters or variables
dinamically to the templates of the admin interface, something like
this:
class TestModel(models.Model):
...
def do_something(self):
return '{{ "col name"|upper }}'
do_something.allow_tags = True
...
class Admin:
list_display = [...,'do_something'...]

A cursory look at the django-evolution source reveals what I expected: it looks at the in-memory model class. Ordinarily, this will be created by writing a model in models.py directly, but it's quite possible to use database-backed model definitions and have them show up in an app's 'models' module. Django evolution would then have no way of knowing whether the model was written out by hand, or generated dynamically. I admit, I haven't done a thorough test of storing model definitions in a database, but it really should work, and without having to automatically build/edit your models.py file. Now that Django Evolution is gaining traction, I may set up a separate Google Code project just to create an app for managing dynamic models. I don't know yet though, and I certainly wouldn't have it done in the next few days or anything, so if you have more urgent need, feel free to continue with it on your own. I'd be happy to answer any questions you have about the process, to the best of my ability. -Gul --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

No, what's being said is that a user whose only permission is to "read/view" shouldn't be going into the admin at all. That user is not an administrator of that content. That user is not doing anything to the content which requires the admin interface. So don't have that user go to the admin interface to view that content. Again: the Django admin is NOT DESIGNED for the idea of a user who has only a "read/view content" permission.

It's not so hard. Ok, I'll write my own views but where? Outside of the admin? Say one of this users has permissions to add/modify/delete model A and should only have a read view on model B. Are you suggesting this user should login into the admin site for working with model A and login again somewhere else in order to view the content on model B? I'd like to be able to integrate this new, custom views into the admin but have to figure out which is the best way. In the ideal scenario I would totally "simulate" the look and feel of having a real "view permission": - Model get listed properly in the main page - Some sort of HTML table shows the full content of the record instead of an editable html-form - No modify / delete buttons get shown or they are inactive Any ideas on how to get there?

> From your description, I don't understand why your models need to be > dynamic. If each Item is defined in terms of it's Type and Fields, > then can you not change the definition on an Item by simply adding new > ItemTypes and ItemFields? If you're talking about using ItemField Classes, I could, but then there would no real instances of items other than as a collection of foreign keys, and instead my items are stored in instances of different item field classes. and I get tables that consist of instances of the various types of fields available (i.e. a table full of charfields, which is holding all the data for all the charfields of my items). As for them needing to be dynamic, it's that I want end-users (who wouldn't have access to models,py and the know-how to change it) to be able to add fields to items, like "model" or "manufacturer", etc. to fit their needs. At my current job I use a CRM system that has all these unnecessary fields for all kinds of records. It would be wonderful if the end- users (say, accounting, or warehouse manager, or whatever) could put in the fields as required (which we can do, but we can't get rid of the default ones), so that anyone entering in a new instance of an item could later fill out the fields.

Yeah, I've seen the DynamicModels writeup, but there is that issue of syncing modifications to models. Evolution might help, but as far as I can tell that will look at the models.py file, not database entries, so that brings me back to my original question of whether I should build some kind of script/app to edit models.py files.

The admin site's use of permissions is described here: http://www.djangoproject.com/documentation/authentication/#permissions and it doesn't include any view/read permissions. The Django admin site code assumes any User with "is_staff" set to True can view/read everything. It only uses permissions to limit the ability to add and change objects. Any ideas on how could I implement that in the cleanest possible way? This is not a way in which the admin site is meant to be extended/customized. The admin site is meant for trusted users.

Possibly it does not have appropriate blocks or is just empty?

The list of instructions you are following don't appear to have included the piece that lets Django use Python to access the database, that's what psycopg does. See: http://www.djangoproject.com/documentation/install/#get-your-database-running for pointers on where to get psycopg. (Nor do I see in the list so far the database itself, which you will also need. But I'm unfamiliar with facbackopac. From a quick look at its Google groups page it sounds like it provides an alternative interface to an existing catalog, so I guess maybe you already have a database with this catalog running?)

If the complexity exists at the data level, you may find that Django's 'custom model fields' [1] will help you with that. Otherwise, if the complexity is just presentation/form-based, you can use custom form fields/widgets. See James Bennett's excellent writeup on newforms for more on that (and newforms in general) [2].

View permission for models in the admin
Hi everyone, I'm quite new to Django but so far I'm making progress using and customizing the admin interface. Last nite I realized there is no view or read only permission on models, the closest thing I found was "Can change permission". Any ideas on how could I implement that in the cleanest possible way? I'm using the regular django code from svn, not the newforms admin branch.

Re: Order By Calculated Value??
Yes, What I wanted to do was have a field in my Category model called num_entries, and every time an Entry model was saved, I wanted to increment this by one - but I could not work out how to access the Category model to update just one field per entry (for example if my entry is in Blog and Django, I want to update each blog_categories.num_entries field for that row). Hope that makes sense, as if I can do it this way instead of calculating it on the view, that would make this inclusion tag so much easier.

Using Oracle support and Synonyms
Hi
Just a quick one, if you wish to keep your django instance data
seperate from your production data and still use all the nice nifty
ORM and admin interface, you can just add synonyms to your django
user, then make the following change from USER_TABLES to USER_OBJECTS
in the db code and it all appears to work:
file : Python25\Lib\site-packages\django\db\backends\oracle
\instrospection.py
def get_table_list(cursor):
"Returns a list of table names in the current database."
cursor.execute("SELECT OBJECT_NAME FROM USER_OBJECTS WHERE
OBJECT_TYPE IN ('TABLE', 'SYNONYM')")
return [row[0].upper() for row in cursor.fetchall()]
You cannot of course create tables this way, but it highly usefull for
using the admin interface on existing databases while keeping dango
seperate.

Can you describe what you did that prevented you from saving the computed count? Another solution is to batch compute your counts using a shell script at some frequency. The script could iterate over each category and recompute its counts and store them. Yet another solution is to convert your cats queryset to a list, loop over it to get an entry count, and then sort the list in Python to pass on to your template. So there seem to be many ways to skin this cat. -Rajesh Dhawan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Note the code to build the choices list for your Dataset model ContactID runs only once, when the Dataset model is imported. That is why the choices list does not get updated as you make additions to Contactinfo. From the docs here: http://www.djangoproject.com/documentation/model-api/#choices see the paragraph: Finally, note that choices can be any iterable object — not necessarily a list or tuple. This lets you construct choices dynamically. But if you find yourself hacking choices to be dynamic, you're probably better off using a proper database table with a ForeignKey. choices is meant for static data that doesn't change much, if ever. Really, what you have described here is a ForeignKey -- why don't you want to use that construct?

modelling and multiple fields as primary key
Hi, I'm trying to model a simple application. It will consist of 2 models: - document client_number document_number document_date ... (some additional fields) - document_status client_number document_number document_date status_code comment ... (some additional fields) I am aware, that django will not allow me to create primary key on multiple fields (client_number, document_number, document_date), and will create for each model (table) it's surogate id field as primary key, I'm OK with that. What I would like to achieve, is to add document status, that just before inserting into db, will find it's parent document's primary key, by searching in database for those 3 fields (client_number, document_number, document_date). Could you please help me, or at least point the direction I should follow?

Order By Calculated Value??
Hi there,
At the moment, i'm building a inclusion tag for using on my blog
software to show all the categories, kind of like how Wordpress does
it. The tag works fine and displays the data, sorted in order of the
name:
@register.inclusion_tag("blog/category_list.html")
def category_list(order="name"):
cats = Category.objects.all().order_by(order)
return {'categories': cats}
However what I'd like to do is also be able to order by the number of
entries associated with this category, so it's weight based rather
than alphabetical.
My Entry model has a ManyToManyField linked with categories, and my
Category model doesn't store this number, but for example it
calculates the value for the admin in a num_entries function:
class Category(models.Model):
""" A Category is a way to manage the taxonomy of the site"""
name=models.CharField(max_length=50) #The name of the category
description=models.TextField()
slug=models.CharField(max_length=75, null=True, blank=True)
active=models.BooleanField()
generate_feed=models.BooleanField()
parent=models.ForeignKey('self', null=True, blank=True)
.
def num_entries(self):
"""Returns the number of entries in this category"""
return self.entry_set.count()
num_entries.short_description = "Number of Entries"
I'm wondering if there is any way possible to get this value in my
inclusion tag? I had tried before to store this value in a field, but
couldn't get it to save, otherwise I would just pass in a field
'num_entries' so if anyone can suggest anything, that would be great.
Thanks,

That seems to run the whole output of mytag through the filter. I just
need the parameter itself filtered. In reality mytag gets two arguments,
'label' and 'value' and spits out a few lines of HTML. It displays some
user profile information. The value of each property may need to be
filtered differently, e.g. if it's a dollar amount I want to attach my
filter '|dollarformat' that turns an integer like 1000 to a more
readable "$1,000". For other properties I may want other filters. In any
case I only need to filter the argument, not the tag output.
I could probably do something like message.split("|") and run the
filters (if any) manually. That is, import them from
django.template.defaultfilters and pass the output of resolve_variable
through them. But what if the filter in question is imported from a
non-default tag library? How do I find what to import then?
BTW Wouldn't it be more user-friendly to resolve the variable and run
all the filters yet before the custom tag gets called?

Re: Dynamic class definitions
You might take a look at my writeup on dynamic models,[1] which specifically covers a way to specify Django models in a database, which can be changed at run-time. However, I haven't looked at what it would take to actually commit changes to the already-synced tables. I have a feeling Django Evolution[2] will help with this, but I haven't done any testing with it yet. -Gul [1] http://code.djangoproject.com/wiki/DynamicModels [2] http://code.google.com/p/django-evolution/ On 12/5/07, DeliciousPy <[EMAIL PROTECTED]> wrote: > > I'm thinking of trying to start making a CRM/ERP system, I had just > started working on an inventory app, when I ran into a problem. > > I want to be able to change the definition of an existing class (and > the associated parts of the DB) during runtime, from a web interface. > > > I'll describe the model I want to implement... > Say I have three classes: Item, Item Type, (and possibly) Item Field > > Items would consist of an item type, and item fields (separate from > the so-named classes) > > Item types would specify groups of item fields shown in item records > (instances of the item class), and would also specify how the fields > interacted with other parts of the database (ie accounting, sales, > etc) > > Item fields would consists of a field name, a field type and a > description of the field.

Look at the "filter" templatetag [1]. You must do something like
{% filter upper %} {% mytag something %} {% endfilter %}

Re: Problems loading fixtures using loaddata
Thanks Russell for responding. I'm sorry for replying so late. I have no longer problems with foreign keys. I can't tell what was the problem but outputing fixtures for each model (one file per model instead of one file for all models) don't get me the error anymore. However, I still have problem with loading image files. Here's what I get: Loading 'initial_data' fixtures... Installing xml fixture 'initial_data' from 'C:\workspace\apparto\.. \apparto\contact\fixtures'. Installing xml fixture 'initial_data' from 'C:\workspace\apparto\.. \apparto\building\fixtures'. Problem installing fixture 'C:\workspace \apparto\..\apparto\building\fixtures\initial_data.xml': [Error 3] The system ca nnot find the path specified: u'/static/photos/2007/11/28' What is strange is that for one model defined in "building", images load correctly whereas for another model, it doesn't, even if for both models, images path is under the same root (/static/photos/). I tried to put all the pictures in the same folder but surprisingly, I get the same behavior: images are found for a model but the path is not for the other model! I guess it's not much information, but maybe it is enough for you to point me in the right direction. Thanks!

Custom template tag and filters in resolve_variable
Hi all,
for the project I'm working on I needed to create a custom template tag,
call it 'mytag'.
If I use it as {% mytag something %} everything goes fine (where
'something' is a string passed to the template).
However I can't add any filters to that 'something'. As soon as I do:
{% mytag something|upper %}
I get an exception:
VariableDoesNotExist at /test/
Failed lookup for key [something|upper]
That leads to a code in MytagNode.render() method:
actual_message = resolve_variable(self.message, context)
where self.message is the argument passed to the macro, in this case
it's a string 'something|upper'.
Is there an easy way to run all the attached filters in MytagNode?
Thanks!
Michal

Initializing a selection (choice) field
Hallo I have two applications in a project. One of the the field in one application is a "choice" field. The content of this choice field has to be assigned by some attribute of other application's field. With an example it will be more clear to explain it. Two applications: A and B in a project (g2ps). In application A I have defined a model in which one filed is a choice: from nlscia.contactinfos.models import Contactinfo class Dataset(models.Model): .. contactID = models.IntegerField(choices=[(f.contactID, '%s: %s, %s %s' % (f.contactID, f.givenName,f.surName, f.organizationName)) for f in Contactinfo.objects.all()]) And in application B I have defined the "Contactinfo" class Contactinfo(models.Model): contactID = models.IntegerField(primary_key=True) givenName = models.CharField(unique=True, maxlength=100) surName = models.CharField(unique=True, maxlength=100) organizationName = models.CharField(maxlength=100) ... But what is actually the problem? If I change or add some information in one of the 'Contactinfo" field and back to other application to see this changing, I don't see any changing in 'choice' list in other model. Only I can see this changing if start again the server. Isn't it possible without any redesign of data model? I mean to redefine data model based on some relationship as 'Foreignkey' or 'ManytoMany' for example.
