Re: Admin interface
Either override templates for specific models or use javascript (js property of the Admin class) to change the fields. I think that it will be also possible to change the field type with the newforms admin. Reference: http://www.djangosnippets.org/snippets/35/ Good luck!

Template Tags
I have a template that loops through a simple query set and displays the data in a table. I now need to add another column to my table. However, the data in the new column is a calculation based on two of the other fields in that record. I presume that this can be done using a template tag, but I can't work out how it can be done. I can't see how I can pass the values of the other fields into a tag. Can anybody please advise the best way to do this.

Re: Intializing newforms Form objects
I am struggling right now with the same concerns :-)
I have a hand-written form for a model with ManyToMany field.
So far, I noted a few things that helped me come to a working
solution, but maybe not really elegant...
The form initialization with an object looks like this (I hope...):
my_form = MyForm(initial=my_object.__dict__)
=> ManyToMany fields do not show up in that __dict__.
I had to add them by hand, turning the above one-liner into this:
initial_values = my_object.__dict__
initial_values.update({'m2m_field' = [obj.id for obj in
my_object.m2m_field.all()]})
my_form = MyForm(initial=initial_values)
To summarize, I built the list of ids from the ManyToMany relation to
my form, appending that list to the dict passed as initial data.
I am not really happy with that solution, maybe some more advanced
newforms user may lead a better way.

Re: myghtyboard forum problem
I've never seen it, so I'm just speculating here, but I think it's
throwing a wobbly cause you don't have any topics in the forum yet.
Looking at the source, I see:
class Forum(models.Model):
...
forum_topics = models.PositiveIntegerField(default='0', blank=True,
verbose_name=_("Topics")) # number of topics
I think if you add null=True there (and update the DB to match) you
should be OK.

I don't know of any Python library that converts from HTML to LaTeX.
However, writing one should not be that difficult. It is at least much
easier than writing a LaTeX2Html translator. You could parse the HTML
code using for instance elementree[1] and Beautifulsoup[2]. You can
then iterate over the parsed html tree and output corresponding LaTeX
markup:
name -> \section{name}
name -> \subsection {name}
-> \begin{itemize}
text -> \item text

Re: Intializing newforms Form objects
Anders, I think the simple answer is for foreign keys (including ChoiceFields when they're foreign keys), you want to pass it the id/pk of the object. If the ChoiceFields are a list of tuples, just pass it the value. For multiple selection values, pass it a list of the values you want selected. I have an example here where I store the value as a comma-delimited string, and use a custom widget to convert it to a list: http://www.djangosnippets.org/snippets/23/ -- Jeff Bauer Rubicon, Inc. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

How to implement multi-level cascaded DISTINCT JOIN using django's object model?
Hi all,
I have a data model like this:
* a `user` has multiple `questions`
* a `user` could give multiple `answer`s or `comment`s to any
`question`s.
So here, there are
* a one-to-many relationship from `user` to `question`
* a many-to-many relationship between `question` and `answer`,
`question` and `comment`.
Now I need to pull out a list of all the questions a given user has
either answered or commented on. I could do `user.question_set` or
`user.answer_set`.
Now if I write a template like this:
` {% for answer in user.answer_set %}
... {{ answer.question. ... }}
{% endfor %}
`
I could end up with showing the same questions many times.
I know for sure that this task is not that difficult if I retreat to
using `JOIN` and use raw sql for my query. But I'm wondering does
Django offers a neat solution for this question without using raw
sql?
Thanks,
Alex

I'm hoping to make a generic function that would do both __dict__ and
handle m2m fields (o2m fields as well) that would let you one off
these kinds of things. The problem with this stuff being that if you
have an object with any signifigant number of m2m fields there's just
a lot of cruft in your view.

More or less, yes. I have a Django model (from my original test code): class ResourceSchedule(models.Model): description = models.CharField(maxlength=64) daymap = models.IntegerField() monthmap = models.SmallIntegerField(default=4095) period = models.SmallIntegerField(default=0,choices=RESOURCE_SCHEDULE_PERIODS,validator_list=[validators.NumberIsInRange(0,6)]) frequency = models.SmallIntegerField(default=1) time_from = models.TimeField(default='09:00:00') duration = models.TimeField(default='00:30:00') date_from = models.DateField() date_to = models.DateField(null=True) Which covers all the rule bits I will need. The daymap and monthmap are used depending on what the period is (Weekly, Monthly etc.) to store exactly wich days & months the event should repeat in. I store these as a bitmap for minimizing data storage, but it is easily searchable with SQL and the bitmaps can be simply expanded to lists for display in forms (as Checkbox Lists for example). You could of course store the days/months more explicitly in your table. frequency is the interval part of the rule giving you every 'n' weeks for example. Its pretty easy to then find the ResourceSchedules that might be candidates for having events in your datefrom/dateto period and shoving them into and rrule/rruleset. It might be overkill for some simple tasks but I need the flexibility. This way I can store/generate just about any repeating pattern I care to think of.

Mostly I'm cool with that, but one thing just isn't clicking yet: Your date_from and date_to fields, I'm guessing these represent the from/to dates of the *original* event, and aren't affected by repetitions? So if that's the case, how do you initially pull your ResourceSchedules out of the database? It looks to me like you'd have to pull them all out (ie. ResourceSchedule.objects.all()), generate rrules for all of them, and see which of the rrules fit into a desired timespan. Is that right? By the way, it warms my heart to see you storing bitfields. My area is embedded devices, not web stuff, so I often spend my days working with bitfields and masks and such.

For my system they represent the period that this schedule is valid for and therefore the absolute extent that rrule can generate dates for. For my application I don't have to pull them all out. I'm writing a booking/scheduleing system and mostly people will search for "things" on a particular day(s) or for a particular month or between two specific dates etc. Using the bitmaps and simple bitwise math I can pull out just the ones that are *likely* to have dates in them. You could always store another marker or two to give a good first line SQL filtering depending on how you want to look for them. The idea is to probably get a few more than you might need, but not *too many* more! Finding all the records that fall on a monday or in the month of May is pretty easy with the SQL, then just rrule them to find the actual dates depending on the other repeat criteria. Otherwise you would have to pull them all out yes. However, if you have rules that repeat on every day or every other day you are not likely to have very many of them for any one specific calendar. Also I store these Schedules as a top level table. I then create Resources (Events?) that "use" a specific schedule. This way I can have lots of Resources that use the same Schedule, again minimising the number of schedule records. You can then create nice names for the schedules (in the description field), call them "Weekly", "Monthly", "Every second Thursday" etc. and have a pick list of common schedules to assign to events or whatever. Again, it's probably overkill for a simple calendar, but damn powerful!!

How about this: Question.objects.filter(answer__user_id=userID) - this
should give you the question objects for which the user has given
answers. Extend the filter with a Q clause to do the OR for comments.
You may need to throw a .distinct() in there as well. I've got a
similar thing that works, I'm just not sure about the exact syntax for
your case.

Permalink decorator and generic views
I was happy to find the addition of the permalink decorator in the
development version as a help in removing hardcoded paths from
get_absolute_url() methods.
Unfortunately, using it requires that you define a custom view (even
if the custom view simply returns a generic view). Interestingly, you
can actually refer to a generic view in get_absolute_url():
def get_absolute_url(self):
return ('django.views.generic.list_detail.object_detail',
(str(self.id),))
get_absolute_url = permalink(get_absolute_url)
but it seems to return the first reference to that generic view in the
URLconf. Thus, what would seem to be a common development pattern is
disturbed: defining URLs that point to detail views "directly" using
generic views.
Just a comment ...

Re: myghtyboard forum problem
HI baxter,
I did exactly as you proposed, but the result is unfortunately the
same.
I've even created fresh database, but when I go to Admin, create the

error page saying as above...
Some other idea, what could cause the problem?

Authenticating against Django's user database from Apache + FastCGI

Re: myghtyboard forum problem
Did you alter the db so it would allow that field to be null? Better
yet, now that I look at it.. forget making it null. Make sure it's
defaulting to 0, like it's supposed to.

It seems we all have this problem. :) I was thinking about doing something similar to what Gary's doing, but I'm more concerned with fast access than minimal records. Also, there's a "reasonable" window of time for which we'll ever have records, say 10 years. As such, I was thinking about having an Event model with recurrence rules (perhaps admin'd with a little DSL), then blowing out a lot of EventTime records for all the occurrences. Editing would always be to Events; EventTimes would be regenerated upon Event save. The reduces queries to a simple date range, allowing very efficient index usage. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Marking a DateField event as "repeating"
Yeah, I'd actually considered that. We do use that method on another product. The big upside is that you don't have to store exceptions if you remove just one date in the future from the recurrence pattern, you just remove that one date record from the database. There can be a big downside depending on what you are using it for. I'm using this sort of model for a "Resource Availability" kind of thing. Bookings/reservations etc. can be made against the available resource occurrences. If you want to change the schedule, you have to delete, re-insert or at least update all the actual records in the database, possibly all of these. If you have bookings against the original pattern then what to do with those existing bookings becomes a problem. You also have to consider storage. Several 10 of millions of explicitly stored dates might become a problem :) Basically the problem needs to be thought through from beginning to end. Not only how you are going to query the records, but also how you might update them together with any (possible) dependent records. Bottom line options: Store minimal data (rules) and dynamically regenerate actual dates on query. or Store actual absolute dates (possibly with the original generation rule) and work out how to update them. Storage and efficient query as opposed to raw cpu power perhaps? It's not always easy. Regards, Gary.

I think you're on the right track with this. I have used a similar approach in a few situations. I think it is much more robust to add a record to a queue and have a separate process do the long running tasks. The interface can then check the queue and display the status of the tasks.

If it fails to convert the video for some reason, you can show it as "failed" and maybe give a "try again" option.

Newbie with a question about Models, Managers and NCAA brackets.
Long time lurker, first time poster . . . (I would have asked more
questions before, but the answers have always been in the archives.)
I'm working on an app to show the rapidly approaching NCAA tournament
brackets, and am having some trouble with it. Since I'm quite new to
Django I thought I'd find out if my approach is the right way to go
before I invest any mroe time in it.
My model has two objects: Teams and Games:
Teams is pretty straight forward, with fields for name, region and
seed, among other elements that are pretty flat.
The games model is somewhat more complicated with fields for a gameID,
round, region, a winner, the seed x2 (if it's in the first round),
Previous Game x2 (if it's after the first round), and two teams. I'm
trying to use a manager to pull the teams in from the winners of the
previous games(or from the seeds/regions if it's the first round).
Does this sound like a good way to do it?
I'm including the model code (please don't laugh). The commented out
parts are where I've been having some trouble with the managers.
Any tips and suggestions would be greatly appreciated.
oh, and I'm running 0.95.1

Re: myghtyboard forum problem
What do you exactly mean by saying: "Did you alter the db so it would
allow that field to be null?"
I returned to previous version without "null=True", syncdb, but still
same... :-(
I have downloaded code today. Is it possible, that thre would be some
little bug currently? Does somebody tried recently?
Thanks for any idea.

Re: myghtyboard forum problem
Go to your database in phpmyadmin or something and see what that field
is doing. I don't think it's set up to insert the default value of 0
I grabbed the code for Myghtyboard right when it was first released
and have modded almost all of it by now, but that line is exactly the
same in mine. I think the problem is in your DB. Why, I'm not sure.

Re: myghtyboard forum problem
All Right. It seems to be a problem somewhere else:
Both, localy and on server I run python 2.5. It looks like, that
diamanda installation procedure is calling older python version
2.4 ??? Is it possible?
sample:
[EMAIL PROTECTED] raw]$ python manage.py syncdb
[EMAIL PROTECTED] raw]$ cd ..
[EMAIL PROTECTED] django_current_python_25]$ export
DJANGO_SETTINGS_MODULE=raw.settings
[EMAIL PROTECTED] django_current_python_25]$ export PYTHONPATH=$PWD
[EMAIL PROTECTED] django_current_python_25]$ django-admin.py syncdb
Traceback (most recent call last):

ImportError: No module named wiki
It's over my head yet. Somebody has experience with that?

Re: How to implement multi-level cascaded DISTINCT JOIN using django's object model?
Thanks a lot, Atilla.
`Question.objects.filter(answer__user=user).distinct()` returns
exactly what I expect. This is wonderful, thanks a lot. I also
recheck the django manual and found this solution has a name as "query
over related objects" (http://www.djangoproject.com/documentation/
db_api/#queries-over-related-objects). This is really powerful yet
simple enough.

Re: trying to translate a join query to django
After digging through the messages here, I finally just did a custom
query. Here is the function I used that will spit out a template-ready
dictionary:
---
def csql(self,query,qkeys):
from django.db import connection
cursor = connection.cursor()
cursor.execute(query)
rows = cursor.fetchall()
# build dict for template:
fdicts = []
for row in rows:
i = 0
cur_row = {}
for key in qkeys:
cur_row[key] = row[i]
i = i+1
fdicts.append(cur_row)
return fdicts
-
it is called like so:
-
qkeys = ['id','name']
query = "SELECT id, name FROM stuff"
div_list = csql(request,query,qkeys)
In the template, it can be used like so:
---
{% for div in div_list %}
this is an id: {{ div.id }}, this is a name {{ div.name }}
{% endfor %}

What's available in a view
This is somewhere between an observation and a question. I am writing a view that needs to know "some stuff", in particular HTTP_ACCEPT_LANGUAGE. As I read the developing book and look at the on- line documentation, it is not clear what is available and, probably more important, what is good practice to use it. To that end, I am going to toss out a more generic comment. Unfortunately, I don't have a good explanation to back it up. When I read "Agile Web Development with Rails" I felt that while I am more comfortable with Python and Rails seems a bit convoluted to me, that I knew more along the way. That is, with that book, I found the author anticipated my next question most of the time. I don't know how to define this but the approach in that book (and Programming Ruby) somehow makes things seem easier. I think that is going to be an important piece of promoting Django so consider this an observation from an outsider looking in rather than any serious criticism. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Page Not Found 404
Hi, Yes, I am using date based generic views for my blog. Then I am using the admin to create posts. So, I think the cause is the JS control in admin. Today my posts can be viewed correctly.

I don't know if this is the (only?) issue, but you're using
backslashes for your path, and "d:\mysite\templates" has a "\t"
in it. You don't have it specified as a "raw" string, so that's
getting expanded to "d:\mysiteemplates" which isn't likely
what you mean. You likely want either
'd:/mysite/templates'
or
r'd:\mysite\templates'

I agree that it's something we need to work on, especially with views; unfortunately, a view can technically do absolutely anything that's legal to do in Python, so long as it accepts a 'request' argument and returns an HttpResponse, so it's a bit of a hurdle :) With respect to the Accept-Language header, the request/response docs[1] mention that it, and any other HTTP headers you want to look at, are available in request.META -- in this case, it's request.META['HTTP_ACCEPT_LANGUAGE'].

Re: howto add join table field?
hello, i suspect you cannot do this (but i can be wrong because i myself do not have much experience with django). you could make your own association table manually in stead of using ManyToManyField. of course in this case you won't have FOO_set methods on your models. konstantin On Mar 8, 10:04 pm, "Greg Donald" <[EMAIL PROTECTED]> wrote: > How can I add a field in a join table? > > I have this: > > class Item(models.Model): > name = models.CharField(maxlength=32) > > class List(models.Model): > name = models.CharField(maxlength=32) > items = models.ManyToManyField(Item) > > which creates the 'list_items' join table fine, but then how do I put > a field in that same table? > > When I try to add something like this: > > class List_Items(models.Model): > quantity = models.IntegerField() > > I get errors: > > _mysql_exceptions.OperationalError: (1050, "Table 'stuff_list_items' > already exists") > > Does Django have join models or the like? > > Thanks, > > -- > Greg Donaldhttp://destiney.com/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I'm trying to trim down the problem to something smaller. I *suspect* there is a problem in your URL configuration and you have made a typo there.

For django, just print won't return the result, but print output in
the console(if you are using develping server), you should return a
HttpResponse() object, and the good format of the returned data is
json, so there is a example from your code:
from django.utils import simplejson
s = request.GET.get('q', '')
#current_tags = list(Tag.objects.all())
result = []
for tag in Tag.objects.filter(name=s):
#if (search (s.lower(), tag.normalized_tag)):
#print "%s" % (tag.normalized_tag)
result.append(tag.normalized_tag)
return HttpResponse(simplejson.dumps(result))
If you are using Firefox and installed Firebug plugin, you can see the
response message.

But I'm still getting 20 to 40 group email copies a day. Please, remove my id and address from the Django users group. Thank you.

RadioSelect attrs
I am working with newforms and am wanting to set the class of the
produced with a ChoiceField using a RadioSelect widget. I assume it
should be something like this..
field = forms.ChoiceField(choices=CHOICES,
widget=forms.RadioSelect(attrs={'class': 'fun'}))
output would be
Field:
Choice 1
Choice 2
etc.
Can anyone help or does this need to be a feature request?
Thanks,
Sam
