Re: importing users from another db
I can answer for the settings part :)
Make sure your project is in your PYTHONPATH environment variable and
that DJANGO_SETTINGS_MODULE also exists as an environment variable.

Re: Database caching, querysets not evaluating?

didnt quite work as I intended. I see now that a new connection is
created for each thread/polling I create.
This brings me back to the original question... how can I force a

Djangonauts at EuroPython?
Hello fellow Django-users! Me and my colleague are attending to EuroPython conference (in Vilnius, Lithuania) tomorrow (9.-11.7.) and we were wondering if there are any other Django-users around. It would be great to arrange a Django-meetup or something. We arrived to Vilnius yesterday and are leaving on Friday evening. If the weather stays like this, I'm sure some company at the local bars (after the conference hours) wouldn't hurt =) Yours, Ville Säävuori http://www.unessa.net/en/hoyci/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Maybe you are right and this is the solution my current Python/Django knowledge seems to be sufficient for.

I don't agree in that point - from my perspective Django seems to be the system, which is used by admins only (admin == user), because admin's interface is pretty and much more user friendly comparing with techniques for building ordinary user interface described in documentation/tutorials, even if admins are used to talk to machines via text mode consoles :-O I'm going mad if it is true that there is a valuable piece of software, which is not possible to reuse in Django based applications. Please, is there any other solution than copy&paste functions from admin.main module and modify source code properly?

arrays in templates
I have this working with some extra code in my view, but I would like to know
how I could have done it in the template:
# view.py
from datetime import datetime, date
# Week starts on Sunday
c=calendar.Calendar(calendar.SUNDAY)
# get all the dates that will be displayed,
# including the tail and head of previous/next months.
# (a list of weeks, each week is a list of 7 dates.)
dates=c.monthdatescalendar(year, month)
# array, ['Monday', 'Tuesday'.. 0 is Mon.
daynamesarray=calendar.day_name
# I can't figure out how to use the array in the template.
# so I am building a list here.
# Use the first week of the calandar, which is handy
# because it makes sure the week starts on the weekday we want it to
# (like Sunday)
daynames= [ calendar.day_name[d.weekday()] for d in dates[0] ]
{% for dayname in daynames %}
{{ dayname }}
{% endfor %}
So what would the template code look like that uses daynamesarray and dates?

forms and designers
I'm a designer new to django and the templating system has been pretty easy to pick up. The area that I have a problem with is the form shortcuts - the auto-generation of html is a big pain and causes me a lot of headaches in terms of being able to manipulate the elements directly, not just in terms of creating a page initially but especially when modifying one. I know it makes the programmers jobs easier because of the built-in data validation but it's a the cost of my productivity, as I see it now. I just don't have the same level of control over the actual html compared to the rest of the templates. Can anyone share their tips on ongoing work with forms and designers? I asked a particularly well-known web designer on a django team how they deal with the issue and his answer in short is that they don't: he creates all the html by hand, including any form elements. Since I imagine that his programmers have the same data validation issues that the developers at my work do, I'm curious how they get around it. -- Al Abut -- web designer, crimefighter http://alabut.com -- --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Parent / Child Categories and QuerySet filters
This question may have been asked a thousand times, but I'm not sure
how to use the Parent/Child category database model given here:
http://code.djangoproject.com/wiki/CookBookCategoryDataModelPostMagic
I have a model Item with category as a ForeignKey. I'd like to loop
through all top level categories and then print all items in that
category or its child categories. Here's what I've got for a view:
def catalog(request):
# Find top level categories
dict = {'categories':{}}
cats = Category.objects.all().filter(parent__isnull=True)
for cat in cats:
dict['categories'][str(cat)] = cat.getFullItemSet()
return render_to_response('catalog.html', dict)
And then in the Category model, I've added a function that merges all
the QuerySets from its child objects:
def getFullItemSet(self):
items = list(self.item_set.all())
for child in self.child_set.all():
items.extend(child.getFullItemSet())
return items
This works, but it seems sloppy, and inefficient since it requires
database hits. Can anyone suggest a better way of doing this? I'll be
looking into using Q objects to filter through Item.objects.all() list
in the meantime.
Thanks,
Dan

Re: MySQL Got packet bigger than 'max_allowed_packet'
Hello I wrote a test case using mysldb with direct python calls and using the django model classes to insert various sized binary data into a blob field. First I changed the value of max_allowed_packets in my.cnf to prove/disprove that mysqldb/django are using it. Conclusion they do use my.cnf and setting it to 1k will always cause the error. So I set it to 32M and tried loading the large data. Both the mysqldb direct call and django model class routes fail at some point between 10M and 25M with the max packet error. Seems like a bug in mysqldb as the same mysql insert works up to 30M. I'm going to see if there is a later version to try.

problem with session persistence
I am building an online test taking type of application and I am
having an issue with one of my session variables...
The code looks something like this: (A lot removed for brevity)
The first time around I do the following to initialize the list:
question = Question.objects.order_by('?')[0]# Get
a random question
request.session['question_list'] = [int(question.id),]
Then on the second pass, I do the following:
questions_asked = request.session['question_list']
question = Question.objects.order_by('?')[0]# Get
a random question
request.session['question_list'] =
questions_asked.append(int(question.id))
Now this partially works. The first page of my test asks how many
questions you want and then once that is entered, it takes you to the
first question. My debugging output shows that I do indeed have a list
with the current question's ID in it. I answer the question, it takes
me to page 2. Now my debugging information shows I have two ids in my
list, the first question and this second question. Now, when I answer
this second question, I get:
AttributeError at /flight/test/
'NoneType' object has no attribute 'append'
Here is the traceback info:
Traceback (most recent call last):
File "/usr/lib/python2.4/site-packages/django/core/handlers/base.py"
in get_response
77. response = callback(request, *callback_args, **callback_kwargs)
File "/var/www/localhost/django/flight_school/knowledge_test/views.py"
in take_test
42. request.session['question_list'] =
questions_asked.append(int(question.id))
AttributeError at /flight/test/
'NoneType' object has no attribute 'append'
If I change the line that appends it to the following:
try:
request.session['question_list'] =
questions_asked.append(int(question.id))
except AttributeError:
request.session['question_list'] = [question.id,]
Again, the first two are ok, the third shows the
request.session['question_list'] contains 'None' The next question
show the previous question and the current question. Then none, then
previous question and the current question, etc
This is with the 0.96 version. Am I doing something wrong? Should I
try to upgrade to the svn version? I am using this with apache/
mod_python but the same thing happens with the development server.

dump an object
For quickly displaying an object on a page (in particular from a generic view),
is there something that is slightly better than {{object}} ?
Something between that and the admin look/feel. The goal is to show someone

make it pretty some other day.

Keep in mind that Django doesn't contain any magic syntax parsers - it's just Python code. If what you type doesn't make sense as raw Python, it won't work in Django, either. So - does nameChoices have an attribute called Name? No - nameChoices is a list of objects. Each object in the list might have an attribute called name, but that's not the same thing. To get this example to work, you will need to do a list comprehension to convert the list of objects into a list of names: widgets.Select(choices=[obj.Name for obj in nameChoices]) You will also need to keep in mind the time at which that comprehension will be evaluated. Depending on how you define and use your form, you may find that the choices list isn't as dynamic as you would like. This may be due to the queryset getting evaluated at time of definition, rather than at time of use. If it is evaluated at time of definition, it won't get re-evaluated each time you use it, so the choices list won't be updated if names are added or removed from the list. You may find it necessary to define a function that returns the list, and use that function in the 'choices' definition.

Well - you are getting two poll objects because... there are two poll objects in the database. To delete one, you need to select a single object, and call delete() on it. There are many ways you could do this - which one is correct will depend on which data you want to keep. However, here are some examples of ways to select and delete objects: Poll.objects.all()[0].delete() # Delete the first object in the result set Poll.objects.get(pk=1).delete() # Delete the object with primary key of 1 Poll.objects.get(name='Foobar').delete() # Delete the object with a name of 'Foobar' > 2) I can view the Admin screen but I am still unable to view the poll > app. > I've added a new class (see below) to mysite/polls/models.py but > the Admin screen remains unchanged. > > class Poll(models.Model): > # ... > class Admin: > pass > > Any help would be appreciated The most obvious reason for this is that mysite.polls isn't in your INSTALLED_APPS list. The second reason would be that the web server hasn't loaded the change to the Poll model. If you are using mod_python, you will need to restart apache; if you are using the development server, try restarting the server.

Yes, it's possible.
First off, you'd /generally/ want to likely use .filter() instead
of .get() as .get() is designed for getting a single existing
row. The .filter() function returns zero-or-more rows which is
likely what you want.
However in *this* case, because Django doesn't have an __hour
pseudo-property for the filter clause like it has a
pseudo-year/month/day property as described at
http://www.djangoproject.com/documentation/db-api/#year
there's no abstracted way to do it that will work across all the
DB backends.
You can, however, use the .extra() call to pass an additional
WHERE clause to your query object. This would take the form
something like
Post.objects.extra(where="""
hour(app_post.created_at) BETWEEN 9 AND 5+12
""")
However, the syntax varies based on your SQL backend. The above
should work for MySQL. For sqlite, it would be something like
strftime('%y', app_post.created_at) BETWEEN 9 AND 5+12
whereas for PostgreSQL, you would want
Extract(hour FROM app_post.created_at) BETWEEN 9 AND 5+12
I'm not 100% positive on the Sqlite variant, as I'm not sure how
smart it is about dealing with strings vs. integers (it's a
little overhelpful in converting, so you might need a
cast()/convert() sort of call to push it to an integer before
comparing)

Re: forms and designers
A reply by John Shaffer posted on django-developers (didn't realize it
was for "developing django" not "developing with django"):
"We use this in Satchmo:
Discounts
Discount code
{{
form.discount }}
{% if form.discount.errors %}*** {{
form.discount.errors|join:", " }}{% endif %}
Does that give you enough control?"
No, that's exactly the type of problem I'm having, with the
{{ form.discount }} shortcut rather than it being an or
element. The only control that offers me as a designer is
knowing that the id in this case would be "id_discount" as a matter of
convention and that's it - I can't stick a class on it or add any
other attributes, like onFocus or an initial value or all the other
range of stuff I'd be able to monkey with if it was a plain old html
element rather than something auto-generated.
Does using a newform shortcut make things that much easier from a
programmatic standpoint? Or to ask the opposite, is using and
elements in a template make things that much harder for
things like data validation?

Re: forms and designers
Ix5 - thanks for the link, being able to tack classes into the form
elements as they're being autogenerated would help but that method
looks like a pretty convoluted way to just tack on some presentation-
related info, no? Compared to if that element was plain html, that's
the standard I'm holding it to.
What would be rad is if I could work with the django tags as if they
were html, so for example:
{{ form.whatever class="red small" onFocus="someJavascriptFunction" }}

It doesn't affect validation at all. As long as you have a form element with the same name, validation will work fine. All you need to write is .

Re: forms and designers
I use jQuery as a base for my JS, so it becomes pretty simple to
attach the events. I personally don't like putting JS into the HTML
element inline, though, so I'm bias. But I basically just add a script
element to my form page:
$(function() {
$('input#id_whatever').focus(someJavascriptFunction);
});
As for classes, I've taken to applying them to a div surrounding my
input elements. So I have something like:
{{ form.whatever.label }}
{{ form.whatever }}
The CSS isn't much longer...
form .red input { color: red; }

Well, the thing to remember is that you're not just displaying an
empty input element -- it's fairly common, due to the data validation
step, to have to go back and show the form again with values filled
in. Which raises the question of how you take the
in the original form and turn it into
after the validation step -- if you're just writing raw HTML form
elements you have no way of being able to fill in input, or indicate
selected elements, or handle pre-populated data... that's why the {{
form.fieldname }} shortcut exists.

Re: forms and designers
Nathan, thanks for those tips and that looks like a smart way to attach js triggers and classes for css. What about all the other stuff I could do to an html element though, like specify its initial value? Or do I draw the line there as a designer and say that's on the programmer's plate? James, thanks for the clarification about the exact utility of using the form shortcuts. So would I be correct in saying that if you don't need to programmatically manipulate the values of a form element, then you can stick to plain html form elements instead? Not that I don't care about highlighting errors after the validation step - one method we've been using is to modify the text of the associated and give it a class="error" for me to style up with red text and hazard icons and whatnot. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: forms and designers
Ok, so here's what I get when I pinged this discussion to the two python guys I work with: basically, you want to be able to redisplay the data the user entered on a form when you return the page with errors. And that the newform shortcuts are the only way to do that. If that's the case, then fair enough, I'll just have to deal with the existing setup. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: How to execute an external application from View
Just wanted to add a "me too!" +1, any help would really be
appreciated.
I've already tried every variation of os.spawn, and the new subprocess
module:
subprocess.Popen([cmd, arg1, arg2, ... , argN])
That's supposed to be similar to os.P_NOWAIT, and it does behave
similarly. It sits and waits for the process to exit, and then it
refuses to redirect.
My view has the following pseudo-code shape.
view1(request):
args=['arg1']
os.spawnv(os.P_NOWAIT, executable, (decorated-executable,) +
tuple(args))
return HttpResponseRedirect('http://www.yahoo.com')
This view never redirects properly, and no error messages pop up. If
I replace the os.P_NOWAIT, with a os.P_WAIT ... then the view
redirects properly only after the process has completed as expected.
If anyone out there has any ideas at all as to why this is please
share. Even if you don't know of a work around, just knowing why this
happens would be really handy.
Thanks,
Ray

Right look, wrong source. My {{object}} is the results of a calendar display
with a bunch of these: http://dell29:8000/eventcal/detail/600/
I need the detail for Event 600 to be dumped.
I can almost do it with;
http://dell29:8000/databrowse/eventcal/event/objects/600/
But that circumvents the view and {% extends "main.html" %} and the plan to
hear
"yes, that is the right data, lets make it look pretty" and have some clue what
attributes object has, just by looking at the 'raw' version rendered in the
browser.

I mean I am not sure how to make it work with 'object' the generic view hands
off.

Right, so use:
It gets really messy with default values, though.
Hopefully Nathan's tips are enough for you, Al. If not, have your
programmers make a templatetag or filter:
{{ form.fieldname|add_field_attrs:"class='cls'" }}
def add_field_attrs:
[make a dict out of attrs]
return form.fieldname.as_widget(form.fieldname.field.widget, attrs)
A templatetag is better, but I outlined a filter because I'm tired.
The proper templatetag would let you keep all the standard
functionality but still give you the power to add any attribute that
you want.

Re: newforms-admin: defaults and radio select
Hi Allen, I'm no Django expert (in fact, I just started learning a month ago), but I'm happy to share what I have discovered so far. >From what I can tell, the only way to override the default widget or field for a model's database field is to subclass the Options class and override the kwargs['widget'] for the field. For more info, check out my earlier post: http://groups.google.com/group/django-users/browse_thread/thread/bebad28c9701b4d0/180dd29380fbece9?hl=en#180dd29380fbece9 But there's a complication in the case of the radio widget. I could be mistaken, but I was unable to get it to work with newforms-admin. I had to create my own subclassed radio widget and use that instead. (The problem was that the radio widget was returning a "radio field renderer" object, not the actual code as a unicode string.) If you're interested in the details, I can post my solution tomorrow when I'm at the office. But if anyone with more intimate knowledge of newforms-admin has a better solution, I do hope he'll chime in.

I seriously doubt "dell29:8000" is resolvable for me. :)

A working workaround: If javascript is an option, have a look at this: http:// developer.yahoo.com/yui/examples/container/panelwait/1.html Just call the view and then when your external application returns, the view returns the exit status and the popup closes.
