Then, your ORM query will be:
CheckinTest.objects.filter(date_arrived=date.today(), company_name='foo')
Then, in templates, you can say {{ obj.date_arrived }} or {{
obj.company_name }}, where obj is an instance of CheckinTest obtained
by iterating over the query results.

Ok - that's very helpful for us, but the news isn't so good for you :-) It looks like the offending party is PyAMF. The issue is the interpretation and implementation of PEP 302. PEP 302 specifies that a module loader has a signature of: finder.find_module(fullname, path=None) PyAMF 0.5.1, however, implements a module loader as: pyamf.utils.imports.ModuleLoader.find_module(self, name, path): The path argument *should* be optional, but PyAMF's implementation doesn't implement it like that. To make matters worse, the documentation for PyAMF says that it ignores the path argument anyway :-) However, PEP302 also says: "If the finder is installed on sys.meta_path, it will receive a second argument, which is None for a top-level module, or package.__path__ for submodules or subpackages[7]." So, under that definition, Django should be specifying a None value for path. So, this is potentially a bug on both sides. I'll try and chase down exactly who is in the wrong here from Someone Who Knows (probably Brett Cannon, who assisted in the implementation of Django's loader). The fix is trivial on both sides of the fence, but it would be good to know who is in the wrong here (I suspect the answer may turn out to be both Django and PyAMF have bugs). I can't explain why this bug is experienced inconsistently - I can only guess that as a result of the exact usage in your code, the PyAMF loader is only getting installed in some specific set of circumstances (e.g., as a result of hitting a particular view that does an import that in turn causes the loader to be installed). This particular bug didn't get triggered previously because Django's module loading checks were incomplete - we didn't fully cover all the possibilities

This one seems a bit trickier. where would that code live? is that in
the views module for the basket class?
one thing i thought about last night was that i should probably be
doping this a better way. isnt there a way inside django of creating
an object and including it and everything within it(methods etc) with
a proper simple statement? a so i could do something like
{% basket %}
and the basket html would be written out. i could also define {%
basket_total %} and each page would have a summary of the basket?
is this what decorators are for? if not someone tell me the term for
the funtion i'm describing and i'll go away and do the research. im
not asking anyone to write the code for me.
cheers so far

The way you set up the ordering (e.g. 'change_date') just change that to '-change_date'. A minus in front of the ordering keyword reverses the sort order.

Reorder fields in tabular admin inline
Hello, is there an easy way to reorder field display in a tabular admin inline, like fieldsets for common admin forms? Consider the following models, with Bar being edited inline: class Foo(models.Model): field1 = models.CharField(max_length=255) field2 = models.CharField(max_length=255) class Meta: abstract = True class Bar(Foo): field3 = models.CharField(max_length=255) This will result in an display order of [field1, field2, field3], while i want it be ordered like [field3, field1, field2] or [field3, field2, field1]. Since Foo is abstract, i can't just swap the definition order to achieve this.

Re: Django Sphinx Foreign key search

Can anyone point me to the right direction? Do you mean you want the results for Model2 searches to include Model2 instances when when a search string matches text in any of the Model1 instances related to the Model2 instance? If you're don't actually need sphinx in particular but rather you are looking for the ability to full-text search django models, then http://haystacksearch.org/ makes adding search facilities to django projects extremely easy. With haystack and the handily-pure-python whoosh, you can be up and running basic searches of your django models in a matter of minutes. In the case of the foreign key field, with haystack, you could just include texts from related Model1s in the search template for Model2. That's of course a tad wasteful in some ways, but OTOH might be exactly what you want. I don't use django-sphinx so I'm not clear how to do it there, but a conceptually related approach does work with raw sphinx apparently: you can use joins in sql_query in your source declarations. see this: http://stackoverflow.com/questions/1733816/sphinx-and-one-to-many-associations [Obviously, you could also search multiple times for a given search string submission and then do joins on the various results yourself, though that could get painful fast.] Full text search isn't appropriate for everything, so django-filters is also handy to remember for filter query-building type stuff. http://github.com/alex/django-filter -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: djangojs translations not available
So, I managed to fix the problem. If some has the same problem here are some useful infos: - if you have a normal setting.py file then you should not have this problem with djangojs domain translations - if you have your settings.py file split into several sub-settings the locale directory should be inside an application in order to be loaded OR you can define the LOCALE_PATHS variable pointing to it in settings BUT in the second case the djangojs domain translations wont work, see ticket http://code.djangoproject.com/ticket/5494 So, in this last case, the solution will be to pass the locale with the djangojs domain files to one of the installed apps and it will work :) I hope this helps people with similar problems.

admin fieldsets ?
I'm really liking customizing the admin. I would like to know if I could use the change_view.html template with my own form data. My question is how do I setup a fieldset from some arbitrary form such that I can pass it to a change_view.html page. I see that there is a admin/includes/fieldset.html. I'm having trouble following the django code to see how to setup a fieldset so that that template will display the sets nicely. any ideas? do i need to clarify my question? thanks, paul w -- You received this message because you are subscribed to the Google Groups "Django users" group.

Django reversion, AuditTrail, MySQL MyISAM
I'm trying to get rid of a weak Updates table that a coworker had been hacking up for use as a "user was changed on such and such day/ time..." and replace it with AuditTrail but there are a number of confounding issues. AuditTrail: I don't have the User model overridden, how would I hook it into the user model? There doesn't appear to be a way to add request.user to the extra tracking fields as the callback function only gets passed the original instance pre-save. Hard to tell if any real recent changes have been made to it, making Django 1.2 compat a question mark. Django-Reversion: Seems to require a transactional database, however to my eternal chagrin, my coworkers have persistently used MySQL MyISAM. This appears to be a blocking issue preventing me from using reversion. By all means, correct me if I'm wrong. There also isn't any explicit mention of Django 1.2 compatibility. Django-audit-log appears to be abandoned. Is anyone aware of any functional alternatives or solutions to the blockers for using the above?

It's flexible. My though was to define it in views.py, along with its
free referencee PER_ITEM_SHIPPING, though that could obviously
come from a variable or attribute of an object, or out of the settings
module. Then the view would call it on the iterable of purchases
that you're using now, and pass the result to the template.
But you could also make (something like it) a method on a basket
object, taking only self as an argument, and querying the original
iterable itseld, then pass the basket to the template and let the
template say something like:
{% for item in basket.with_added_shipping_item %}

Be careful that you don't go too far the other way here. Just as
logic (and calculation) in the template is to be avoided, not being the
province of the designer, presentation in the code is to be avoided because
it *IS* the province of the designer. Whatever code implements the
iteration over items, you might consider a separate template to render
the individual row, which the code accesses using render_to_string,
for example.
Personally, I don't find iterating over a set of objects each of which
is rendered the same way, simply by accessing attributes, to be
too much logic in the template.
But, yes, you can do such things.
Look for writing your own template tag in the docs. Consider an
"inclusion" tag, where you really produce the stuff in a separate
template, because writing more general template tags is tricky.
Yes, it would still be being done in the template language, but your
designer doesn't have to see it, they just see {% basket %}. This
will require a load tag higher up in the template to load your custom
tag library. Note that your tag will have to presume what the name
of the variable holding the basket is, unless you pass it as an argument,
e.g.; {% basket basket %} (no problem with the names being the same).
Another approach, also using a custom tag library, but writing a filter,
which is easier to get right than a tag, would result in usage like:
{{ basket|basket }}
Yet another way to do something about as good as this is again using
a method on your basket objects. This would have usage such as
{{ basket.items_list_html }} and wouldn't require loading a tag library.
Note: in all these cases remember to mark your return string as safe
so that the template engine doesn't escape your less than and ampersand
characters.

Multi-table inheritance and child model admin add pages

How can I link directly to an _exixting_ Place instance? If I fill in name and address in the child admin add page, then I get duplicates in the parent table.

Re: Multi-table inheritance and child model admin add pages
Thanks Karen for the reply. I overlooked the ticket you mention. Just for reference for others reading in the future this thread, here is a simpler (and more portable) solution other than applying the patch attached to http://code.djangoproject.com/ticket/7623. If you modify the child model as follow (therefore bypassyng table inheritance by setting an explicit OneToOne relation): class Restaurant(models.Model): place_ptr=models.OneToOneField(Place, primary_key=True) serves_hot_dogs = models.BooleanField() serves_pizza = models.BooleanField() everything works as expected also in the admin interface and the final result is the same (although less elegant than multi table inheritance). Note that using place_ptr as the field name (the default name used by the implicit OneToOne relation created by the multi inheritance machinery), it is not necessary to change anything at the database level: just change the model definition (and probably some definitions in admin. py) and all is OK. regards, __peppo On 20 Mag, 22:34, Karen Tracey wrote: > On Thu, May 20, 2010 at 4:26 PM, peppo wrote: > > I have the following problem with admin and multi table inheritance I > > don't understand (django 1.1.1). > > > Model definition > > > class Place(models.Model): > > name = models.CharField(max_length=50) > > address = models.CharField(max_length=80) > > > class Restaurant(Place): > > serves_hot_dogs = models.BooleanField() > > serves_pizza = models.BooleanField() > > > In the admin pages for adding restaurant instances I see the field of > > the parent class (name and address) and the parent instance get > > created as expected. > > > How can I link directly to an _exixting_ Place instance? > > If I fill in name and address in the child admin add page, then I get > > duplicates in the parent table. > > > Is there a solution or I am missing something trivial? > > No, this is not currently supported by the ORM.

I would use auth.User as is. When a new user (no existing django session) enters the code, django creates a user account (random username and password) behind the scenes and logs in the user.

URL Fetching Method Timing Out? Strange problem
Hi, I'm writing a facebook app with django and it is running on google app engine. Part of the application is calculating the strength of a relationship between friends, and classifying it as 1 (weak), 2 (acquaintance), or 3 (close bond). A copy of the relevant code is http://pastebin.com/AtQZDu65 Lines 11 and 12 are the relevant method calls. Looking at calc_strength (which runs perfectly locally, but does take about 5 seconds on my home connection), the only possible values that could be returned are 1, 2, or 3. This should pass as the strength to connectNodes, or if it is not called then connectNodes should have a default strength of 1. However, on execution on my app engine server, the values in the matrix (which connectNodes is supposed to modify) remain 0, which is their initial value. This means that either a) calc_strength is returning 0, or b) that connectNodes is never being called. calc_strength does handle a significant amount of data, but I don't believe that it takes more than about 3 seconds to complete on the app engine server. The view that these methods are called in returns a redirect, could the view possibly move on to the next line of code before calc_strength completes? Any other ideas why this isn't working? Relevantly, this works as expected (matrix has values of 1) when calc_strength is set to immediately return 1. Help would be much appreciated, thanks. -- You received this message because you are subscribed to the Google Groups "Django users" group.

How can you include annotated results in a serialized QuerySet
Hello,
How can you include annotated results in a serialized QuerySet?
I have this serialized query:
serializers.serialize('json',
Song.objects.filter(is_playing=False).annotate(nr_votes=Count('votes')).order_by('-nr_votes'))
However the key/value pare {'nr_votes': number} is not include into the json
result.

is it possible ?
Hi Everyone,
I would like to implement different views in admin panel based on the user.
if the user is any other user apart from admin
then for all those models, the user should just be able to see those
objects,( no change, delete and add).
Those users should also not see the select boxes or basically select all.
So by default django provides three permissions, add, delete,change. I
would like to add one more permission on admin panel.
I know this could be done on our own views through this
class USCitizen(models.Model):
# ...
class Meta:
permissions = (
("can_drive", "Can drive"),
("can_vote", "Can vote in elections"),
("can_drink", "Can drink alcohol"),
)
{% if perms.foo %}
You have permission to do something in the foo app.
{% if perms.foo.can_vote %}
You can vote!
{% endif %}
{% if perms.foo.can_drive %}
You can drive!
{% endif %}
{% else %}
You don't have permission to do anything in the foo app.
{% endif %}
But how to do the same thing on the django admin. Also, how to remove
the select all functionality for selected users.

If you want to do that you may as well use a CGI script with a CGI/ WSGI adapter. Be warned that performance will be abysmal if you reload the application on every request with todays modern fat Python web frameworks. As suggested by someone else, see my blog posts and the mod_wsgi documentation which describe the automatic reload mechanism you can implement.

Re: is it possible ?
In Auth group you can create a group and set the limits.
see different panel maybe use changelist_view
I saw this just be similar to yours'
class Part(models.Model):
is_deleted = models.BooleanField()
//
class PartAdmin(admin.ModelAdmin):
actions =None
def change_view(self, request, object_id, extra_context=None):
if Part.objects.get(id=object_id).is_deleted==True and
request.user.is_superuser == False:
return HttpResponseRedirect('/admin/')
else:
return super(PartAdmin, self).change_view(request,
object_id,extra_context=None)
/
edit admin/views/main.py
IS_DELETED_VAR = 'is_deleted'
class ChangeList(object):
def __init__(self, request, model, list_display, list_display_links,
list_filter, date_hierarchy, search_fields, list_select_related,
list_per_page, list_editable, model_admin):
self.model = model
self.opts = model._meta
self.lookup_opts = self.opts
self.root_query_set = model_admin.queryset(request)
try:
f =self.lookup_opts.get_field(IS_DELETED_VAR)
except models.FieldDoesNotExist:
self.root_query_set = self.root_query_set
else:
if isinstance(f,models.BooleanField) and (request.user.is_superuser ==
False):
self.root_query_set = self.root_query_set.exclude(is_deleted = 'True')
else:
self.root_query_set = self.root_query_set

My immediate reaction is that if IronPython doesn't behave like CPython on a basic datatyping issue, it's a deficiency in IronPython, not a problem with Django. That said, we've made minor changes to Django in order to support Jython and PyPy in (mostly changes avoiding certain CPython-specific assumptions about PYTHONPATH and garbage collection strategies), so I'm not opposed to making similar minor changes in order to accommodate IronPython. However, I'm not an IronPython expert myself, and IronPython compatibility is a pretty low personal priority. What is needed is someone who understands IronPython who is sufficiently enthused to do the work. Volunteers welcome.

This is a known limitation of the serialization framework, logged as
#5711 [1]. More broadly, there is a known need to rework the
serialization framework to make it more flexible. This is one of the
many use cases that needs to be addressed.

Re: is it possible ?
Hi Danfi,
Thanks for your quick response. But can you explain a little more how
can we connect ChangeList class with that function change_view.
Confuse about it.
