Re: How can I delete the default sqlite3 db?
Thanks a lot for the quick reply!
I know how to create the db.
What I need to know is where did django create the default one.
I didn't create it. I just specified I wanted to use sqlite3 in the
settings.py file, and left the DATABASE_NAME intact.

Re: IOError with files uploads bigger than 2.5 MB
hi,
i have done that. I am running the server with the runserver command.
I tried also different directories using the FILE_UPLOAD_TEMP_DIR
without any change. This behaviour is reproducable on different
servers and come up with upgrading to the latest revision of the
django branch. It has been working before. I increased the
FILE_UPLOAD_MAX_MEMORY_SIZE for the moment, but need to change that
back to the FILE_UPLOAD_TEMP_DIR soon.
cheers, tom

Re: IOError with files uploads bigger than 2.5 MB
Do you also get a 'No such file or directory' error when using the
FILE_UPLOAD_TEMP_DIR setting, or do you get a different error?

worked fine last night, no changes but now get DoesNotExistError
I am stumped. Database worked fine yesterday, adding new protein sequence quite happily. Start tryign to do the same today, having made no changes at all to my models or anything, and I get the error: DoesNotExist at /admin/amyprot/sequence/add/ Protein matching query does not exist. Request Method: GET Request URL:http://127.0.0.1:8000/admin/amyprot/sequence/add/ Exception Type: DoesNotExist Exception Value:Protein matching query does not exist. Exception Location: /usr/lib/python2.5/site-packages/django/db/models/ query.py in get, line 252 (ps is it bad that i show all my paths here?) I have three tables: Protein, Mutation and Sequence. Prot_name is the primary key in my protein table. Mutation has this set as a foreign key, the primary key in my Mutation table is Mut_id. I have a one to one relationship from Mutation to Sequence (with me renaming the primary key sequence_id but obviously it is the same as mut_id). I am not using the svn release and can't update to that for a couple of months. Why work last night and not now..how can it break itself over night???!

Probably in your tmp directory: /tmp on most unices, or /var/tmp on OS X (don't know about windows). You can find it by starting the database with python manage.py dbshell, and then on the sqlite prompt, use the '.databases' command. Although, from a quick try myself, while .databases does list some paths in tmp, these files don't actually show up in tmp. I guess it just creates an empty database in memory for the moment, until you save something. Does your application actually work without a DATABASE_NAME? Ie, do you get a database filled with data?

ForeignKey ordering on Models
Hey, I want to have a field on one model link to another model as a ForeignKey. Problem is, this field needs to be declared before the second model has been defined. Example below - latest refers to Album, but Album is below Musician so it won't let me do this? Is there a way of getting around this without having to create another Model just for this? class Musician(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) instrument = models.CharField(max_length=100) latest = models.ForeignKey(Album) class Album(models.Model): artist = models.ForeignKey(Musician) name = models.CharField(max_length=100) release_date = models.DateField() num_stars = models.IntegerField() --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

admin doesn't catch IntegrityErrors?
Hi,
I'm using latest newforms-admin and I have a simple model which is:
class Backend(models.Model):
name = models.CharField(unique=True, max_length=255)
address = models.IPAddressField()
class Meta:
db_table = u'backend'
ordering = ('name',)
In the admin, when I try to add a new object with a name which is
already present, the unique=True constraint doesn't work as expected,
the error is:
IntegrityError at /admin/models_app/backend/add/
duplicate key value violates unique constraint "backend_name_key"
Basically, it seems the admin site doesn't handle unique
constraints...do you have suggestions?
Thanks

Just put the name of the model in quotes:
latest = models.ForeignKey('Album')

Re: admin doesn't catch IntegrityErrors?
I had to come around this doing in the start of the code:
from django.db import transaction
And after the IntegrityError is catched (with a try/except block):
transaction.rollback()
Like:
try:
user.save()
except IntegrityError, e:
transaction.rollback()
Sorry but i don´t have experience with the admin-app to help you on
this, but this did the trick for me.
Cheers.

Re: How to display the images in the template page under the django development server
Hi Eric, There is a bit about it in this excerpt: """ MEDIA_ROOT Default: '' (Empty string) Absolute path to the directory that holds media for this installation. Example: "/home/media/media.lawrence.com/" See also MEDIA_URL. MEDIA_URL Default: '' (Empty string) URL that handles the media served from MEDIA_ROOT. Example: "http://media.lawrence.com"; Note that this should have a trailing slash if it has a path component. Good: "http://www.example.com/static/"; Bad: "http://www.example.com/static"; """ As far i know (please, someone correct me if i´m wrong), this configuration tells Django (on the production mode) which request.path´s are for static files and for performance reasons prevent them of generating full HttpRequests on Django app, as the others, to views. And other things like: they will not pass by middleware´s, context_processors, etc. Cheers :) -- Rui http://ruivaldo.blogspot.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: worked fine last night, no changes but now get DoesNotExistError
My mistake, ran it from python interactive prompt after typing in python manage.py shell (you can tell I am a real newbie). I get all the objects returned that are there, no problem. By the way I have tried the classic turning my computer on and off again ...next stage will be a hammer!

Re: worked fine last night, no changes but now get DoesNotExistError
Could post your view-code at "admin/amyprot/sequence/add/" ?

Re: worked fine last night, no changes but now get DoesNotExistError

Here's my use case: think tags with tag bundles. So I have a list of tags
for an object that are like ("AGroup:Tag1", "AGroup:Tag2", "FluxCapacitor",
"ZGroup:Tag1", "ZGroup:Tag2"). At the moment I'm storing tags like this, as
"bundle:tagname" or "tagname". For display purposes I order them by that
string, and format bundles within a , but individual tags as-is. When
<% ifchanged tag.get_bundle %> (get_bundle is an instance method), I want to
determine whether I need to emit a , so I need to access the previous
tag in the list to determine if get_bundle returns an empty string.
As I write this, "forloop.previous" aside, it occurs to me that an alternate
approach might be for me to provide the unbundled and bundled tags to my
template in separate lists and display the unbundled tags all together
rather than interspersed. Come to think of it, that might actually display
more attractively -- it could be rather ugly to have tags and bundles
interspersed.
Thank you for serving as my
CardboardProgrammerfor the
day. :)

Re: IOError with files uploads bigger than 2.5 MB
Yes, I get the same error message. I tried it with a different
directory within the homedir of the user who is running the server and
also with the temp directory and even without any setting. Either on
Linux or on Max OSX. I also tried to run the server with sudo and I
also tried to write into the directories. With sudo I've got the same
error and writing into the directories was possible.

Because it's not setting the user directly, it's setting a LazyUser object, which is a Python descriptor. Descriptors only work the way they're supposed to if they're set at the class level. Using a descriptor allows it to go through the trouble of getting the user only when it's actually gonna be used, and also cache it for later, so it doesn't have to go through all that extra work more than once per request, no matter how many times the user is accessed. If you're interested in learning more about descriptors, I've written a couple blog posts about it that might help. http://gulopine.gamemusic.org/2007/nov/23/python-descriptors-part-1-of-2/ http://gulopine.gamemusic.org/2007/nov/24/python-descriptors-part-2-of-2/ -Gul --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

This configuration is entirely outside of Django, and specific to whatever webserver you are using. Django doesn't do any special short-circuit processing on "media" urls because you configure things so that Django is never asked to handle any of these requests. In coding your templates, you can use MEDIA_URL to ensure that the static files are given the right prefix to prevent Django ever seeing requests for them. MEDIA_ROOT is used in production in conjuction with the FileField, see: http://www.djangoproject.com/documentation/model-api/#filefield Karen --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Allison: I assume you are using MyISAM tables? They allow you to get into a state where you've lost referential integrity, which could explain the error. Though, Django's admin code follows relationships on delete in an attempt to prevent this sort of thing, so if the only way you've been modifying the DB is with Django admin, this shouldn't really happen even with MyISAM tables. If you (or anyone else) use the mysql command line or anything else non-Django, though, to delete records, then all bets are off. The error makes it sound like a Protein has been deleted without all references to it also being deleted. A full traceback posted at someplace like dpaste.com might help pin down more exactly what is going on. What leve of Django exactly are you using?

In old admin these sorts of constraints were handled by the oldforms
manipulator framework, which did validation. In newforms this validation is
still a work-in-progress, see ticket 6845:
http://code.djangoproject.com/ticket/6845
I'm assuming (someone please correct me if I'm wrong) when newforms-admin
gets merged to trunk and this ticket gets integrated, issues like this will
be handled more elegantly like they were in the old admin. But I haven't
actually had time to experiment at all with the new validation stuff yet.

It wouldn't be difficult, however, to implement your own sessions that don't use cookies. Also is there a directory structure in an web app when using Django? Like in J2EE?? If you are referring to Java namespaces, then yes: Python has them. If you are asking about urls in Django, I suggest you read through the tutorial in the official Django documentation. Good luck!

I was afraid someone would bring up that ticket on this thread. That ticket has nothing to do with storing files in a BLOB field, but instead, its backends allow you to swap out different file systems, such as MogileFS or even Amazon's S3. A BLOB isn't really a file system at all, it's just designed to store a single field, so calling things like blob_backend.save(filename, content) make absolutely no sense. That said, I will concede that some of the incidental changes that #5361 introduces *could* make it a little bit easier to write a BLOB field. It organizes FileField a bit better, so it might be easier to subclass it when making the custom field. It would be an interesting test to see if those changes help in more cases than just those I expected. There's still a fair amount of work to be done between now and having a working BLOB field, and some of the changes in #5361 might make that slightly easier. The rest of it, including the pluggable backend support, will just add completely useless overhead and cause more confusion than it will solve problems. There's already a ticket[1] for adding a BLOB field to Django, which I haven't been following. If it gains traction, I'd be willing to invest some energy in helping it along. For the moment, I'll just settle for asking people not to put too much hope in #5361 solving this particular issue. -Gul [1] http://code.djangoproject.com/ticket/2417 --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Images in MySQL
Hi Luke, I have tried this in an asset management system I am currently implementing for my company, which is ment to store a lots of images (round about 300.000+). Generally it is a very bad idea, at least this is what I have found. I ignored this article http://mysqldump.azundris.com/archives/36-Serving-Images-From-A-Database.html at first, but after some serious testing I have to admit, that everything is true what the author says. So, if you plan to store some images in your database, it might be okay, but if you plan to serve a lot of images it is not. You are better of with storing images in your filesystem and serving them from a seperate http server. Hopefully, I haven't told you something you already know and have already considered.

Thanks Oliver, hadn't researched that yet I have decided to use lighttpd to serve up the images now, looks to be much more reliable.

Change form - populating selected item from a ForeignKey field?
Hi everyone - wondering if someone could point me in the right
direction with this one?
I am trying to populate fields in a form with data from the database
(i.e., a change form rather than an add new form). It works fine for
populating Char/Date Fields but when I do the same for ForeignKey or
m2m fields I loose the information about the items that have been
selected. I.e., for a foreign key I get the dropdown for the foreign
key list but no single item is highlighted as selected.
Below is an example:
models.py:
class SmallDesignSet(models.Model):
title=models.CharField(max_length=100)
priority=models.ForeignKey('Priority')
status=models.ForeignKey(Status, default=2)
concept=models.DateField()
class Priority(models.Model):
priority=models.CharField(max_length=20)
...
forms.py:
class SmallDesignSetSaveForm(forms.Form):
priority = forms.ModelChoiceField(
label='Priority',
queryset=Priority.objects.all()
)
status = forms.ModelChoiceField(
label='Status',
queryset=Status.objects.all()
)
title = forms.CharField(
label='Title',
widget=forms.TextInput(attrs={'size':64})
)
concept = forms.DateField(
label='Concept',
widget=forms.TextInput(attrs={'size':10})
)
views.py:
def smalldesignset_save_page(request):
...
elif request.GET.has_key('id'):
id = request.GET['id']
designset = SmallDesignSet.objects.get(pk=id)
priority = designset.priority
status = designset.status
title = designset.title
concept = designset.concept
form = SmallDesignSetSaveForm(initial={
'priority': priority,
'status': status,
'title': title,
'concept': concept,
})

URLs question
greetings. I'm using the urllib to post data to another site. In the data, I have to pass back a url for an "accept" page and url for a "decline" page. Now my very limited understanding of https posting is to allow you to send data to a website and get a response without leaving the url you are at. The site i'm hitting supposedly sends returns back as url variables/ values rather than as a https post.

Setting the time on a datetimefield
Hi Folks, I have an object with a model.DateTimeField on it. For various reasons, I need to set the time portion of this field to 23:59 when I populate it from a form. datetime = models.DateTimeField() How can I do this? I've tried self.datetime = pForm.cleaned_data['datetime'] self.datetime.replace(hour=23, minute=59) but hour isn't accepted as a parameter to replace. I'm also confused as to how the DateTimeField maps on to a python datetime object, can anyone educate me?

I added ('E Miller', '[EMAIL PROTECTED]') to admins to see if I could at
least check for mail on the server. Still no mail. I'm sure mail to
localhost works because I can do:
$ mail [EMAIL PROTECTED] -s 'test'
etc...
and I do receive the email. I have checked relevant /var/log files and
I can't seem to diagnose this. Any suggestions?
relevant server info:

Re: URLs question
Bobby -
I've used urllib in a django view for grabbing a json feed. You'll
have to figure out how to handle the format you get your response in.
I would suggest firing up an interactive prompt and trying it out...
it's as simple as:
>>> import urllib
>>> response = urllib.urlopen('https://etc...')

Drop into a shell (python manage.py shell) and send yourself a test
message using:
from django.core.mail import send_mail
send_mail('Subject test', 'Message test', '[EMAIL PROTECTED]',
['your_email_address_here'], fail_silently=False)
With fail_silently=False, you will receive some kind of an error
message if that email send is unsuccessful. Use that to investigate
further.
If the above call doesn't show any errors, check your Postfix logs.
Lastly, although this is probably not related to your problem at the

Standalone script + get_absolute_url with urlresolvers
I was wondering whether anyone can help me with a problem I'm having.
I'm running a standalone script outside of the web server to do some
maintainence tasks.
In particular I need to return the absolute url from one of my models,
however when I call the get_absolute_url() method, I'm getting a
ViewDoesNotExist exception raised. A view exists however upon further
investigation I've found that this line of code is causing me some
real problems:
return urlresolvers.reverse('satchmo_product', kwargs={'product_slug':
self.slug})
Basically it appears that Django is concatenating the view path or
similar, so instead of either searching in:
satchmo.shop.views or satchmo.scripts.views
Its actually searching in satcho.shop.views.satchmo.scripts.views
Anyone got any idea how I could overide Django to tell it where to
search for the view or similar?

Do you have a stack trace you can DPaste?
The urlresolvers.reverse function throws an exception if *any* of your
URLs anywhere in the project have a bad view and not necessarily the
one you are trying to reverse map. So, check that you don't have any
URL mappings with undefined view functions (or views with syntax
errors).
Since 'satchmo_product' is a named URL mapping, Django should resolve
that to the right Satchmo view directly without going through any
searches.

Based on your above description, it seems that you are setting the auto_id parameter only during the GET call and not during the POST call. -Rajesh D --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Standalone script + get_absolute_url with urlresolvers
Yeah. I did think that.
As far as I'm aware there aren't any errors in any of the views,
however the views.py file for scripts it is an empty file. I'm
guessing this is the problem in itself.
Is it syntactically correct to have a views.py which is empty but
exists? I'm not really sure of the process Django will use to validate
the view.
I've also pasted the stack trace to Dpaste: http://dpaste.com/64942/

Model inheritance problem in admin
When I save objects from the admin pages, I get COPIES of what I'm saving. When I save them through the API, I don't get the duplicates. I'd like to know if I'm doing something wrong or misunderstanding something. Model: from django.db import models class Process(models.Model): process_name = models.CharField(max_length=100) def __str__(self): return self.process_name class Admin: pass class subProcess(Process): myname = models.CharField(max_length=20) def __str__(self): return self.myname class Admin: pass Given this model (and using the built-in admin) if I create a subProcess, the Process gets created properly. If I subsequently load that process and save it, even without changing anything, I end up with a second copy of that subProcess. If I do this from the API, the second and subsequent saves do NOT create a duplicate copy: In [3]: from procs.models import * In [7]: sp = subProcess(myname='hello world', process_name='command line') In [8]: sp.save() # one object In [9]: sp.myname="good bye world" In [10]: sp.save() # still just one object Thanks for any ideas you can offer. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Seperate project in a subdirectory (Apache 2.2 & mod_python)
Trying to run a separate Django project in a sub-directory while the main project runs in the root. I'm using Apache 2.2 and mod_python on Windows. If my apache httpd.conf includes just the subdirectory I get things working correctly: SetHandler python-program PythonPath "['C:/django-projects'] + sys.path" PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE testproject.settings PythonDebug On PythonInterpreter testproject If I include the domain root, it will no longer hit the subdirectory: SetHandler python-program PythonPath "['C:/django-projects'] + sys.path" PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE mainproject.settings PythonInterpreter mainproject PythonDebug Off Basically, I need to make the second Location directive include everything except /testproject/ and that needs to hit the first directive. The reason for this is testproject is running against django 0.96 while the main project is running against trunk.

You're assuming that model inheritance is supported in the admin interface. It isn't. That would be the main problem here. It's just not worth doing all the work required to change existing admin when newforms-admin is arriving so soon. So you'll just have to wait a bit (or not use the admin for inherited models).

newforms-admin: Interaction between pre_save signals and form validation
I am currently trying to use django-mptt in a CMS project. (More about
django-mptt here: http://code.google.com/p/django-mptt/)
django-mptt manages the implementation of an MPTT tree in a nearly
transparent way. You register your model with the django-mptt
application, and it will automatically add attributes and (if
necessary) fields to your model to manage tree traversal, node
creation and moving, etc.
The tricky parts are implemented via the dispatch.pre_save() and
dispatch.pre_delete() signals. Essentially, these signal handles
update the MPTT specific fields in your model before creating or
changing a node, or deleting it.
This all works fine when I create and save model instances from code.
It fails miserably once I try to create page instances via newforms-
admin.
Here is what I am pretty sure is happening:
When one attempts to save a new record, the MPTT fields are blank. the
pre_save() signal handler that django-mptt registered will populate
them. However, since the fields are Null=False, form validation fails.
Form validation does not attempt to call the save method on the model
which would populate those fields, because the fields are empty and it
knows they should not be empty. Catch-22.
I am trying to find a way to force newforms-admin to skip the
validation of the four fields in question, since essentially django-
mptt has taken over management of those fields completely. Hiding
them, as demonstrated in NewformsadminHOWTO, does not work. The
validation still fails, only now you can't even see the fields which
are causing the problem.
I further attempted to hide the fields from the ModelForm entirely, by
subclassing ModelForm like this:
class PageOptionsForm(forms.ModelForm):
model=Page
exclude=('lft', 'rght', 'tree_id', 'level')
class PageOptions(ModelAdmin):
form=PageOptionsForm
This did nothing. It didn't even hide the fields, so I would presume
that newforms-admin must override the exclude options.
So, I'm not sure where to go next. My next thought is maybe there is
some way to call the MPTT signal handling code before validation
occurs, so that those fields get populated. Haven't quite figured how
to do that yet.

However, this isn't > currently documented; it would mean a bit of digging into the > internals. To extend what Russell's saying a little: by and large, you don't need to specify the type of join. If the relation is non-nullable, an inner join is used. If null results (or non-existent) results are possible in the join (mostly because it's a nullable relation and you're checking for a null value or something like that), a left outer join is used. So Django picks the more-or-less appropriate join type for the relation. The only case where this isn't perfect is where you somehow have external knowledge that the result set won't contain non-existent rows in the join but the relation description is nullable. Django cannot prove (to itself) that no null rows will be generated, so it has to use a left-outer join to avoid missing results. If you were writing the query by hand, you might be able to use an inner join there, but only because of knowledge you have that the database server and Django don't. If you're in that sort of situation and using Django and it's going to make a real difference, that's when you would write custom SQL. Mostly, though, this won't be required (such situations are pretty rare). So don't overthink (or prematurely optimise this). Write the natural queryset filters and you'll find the appropriate join type is used automatically.

Re: Model inheritance problem in admin
Thanks, Malcolm. It was great to see inheritance in the first place, and we'll just wait for newforms-admin to use an admin interface to it.

Thanks Rajesh, good suggestion.
Now I (sortof) know my problem...
File "smtplib.py", line 296, in connect
for res in socket.getaddrinfo(host, port, 0, socket.SOCK_STREAM):
gaierror: (-2, 'Name or service not known')
Not sure what this really means. Doesn't the fact that I can use
'mail' to send mail from the CLI mean my postfix setup is basically
OK? I will keep working on it.

I will keep working on it. There are two ways that mail can be delivered to an MTA (sendmail, postfix, ...) on a system: by connecting to a listening port (the network-based method) and by starting a new process designed to accept a single transaction / piece of email. When you use "mail" to send mail from the command-line, it uses the second approach. When Django sends mail it has to use the network-based approach, since the mail server could be anywhere. So if 'netstat -tl' doesn't show the mail server listening on a port, you've found the problem.

Permissions like "775" mean nothing on their own. Permissions are relative to the user and group involved. When you're running things from mod_python, the important question would be whether the webserver has write permission to those directories in order to write the .pyc files. However, that's only "important" in the sense that it's not really a good idea to allow. Letting your web server only *read* from executable file directories is really important for security reasons. For this reason, Python ships with the 'compileall' module (which can also be executed as a script from the command line). You run "compileall.py ..." as somebody who does have permission to write the directory that holds the executable files and compile them to .pyc files. Then your webserver sees the benefit without opening up unneeded permissions. Read the docstring at the top of the "compileall.py" file for instructions on how to use it.

This looks like some kind of a name server lookup failure.

Yes, that would mean that your Postfix setup is OK. Try setting
EMAIL_HOST to '127.0.0.1' to see if that helps.
Otherwise, try this in a Python shell:
import socket
host = socket.gethostname()
print host
ip = socket.gethostbyname(host)
print ip
If that ip= line fails, it means your server's hostname doesn't
resolve to an IP address. Just add a 127.0.0.1 entry for it in your /
etc/hosts and that should take care of it.

Re: .pyc files not being created
Hi Malcom, Thanks a lot for the detailed response. Sorry if these are basic questions but, what user would my web server be run under (Apache2)? Would it be my username, root, or something else like "apache"? Would I have to run compileall.py every time I change a source file (it seems like I would have to)? I couldn't get compileall.py to work on the command line... Tried 'compileall.py' and 'compileall'. What am I doing wrong?

Very high com_admin_commands with django/mysql
We have been optimizing our server (db and caching) since our recent
launch and one thing we've been looking at is our server status:
Total queries: 4,307,827
Com_admin_commands: 3,754,356
Com_insert: 37,790
Com_select: 1,354,134
Com_set_option: 172,319
Com_update: 52,759
Com_commit: 88,107
(this is approx over 10 hours uptime, 10K visitors/day).
Running Django trunk, mysql Ver 14.12 Distrib 5.0.32, python 2.5,
Debian.
The com_admin_commands seems extremely high. I have tested on another
machine with similar setup and can confirm that almost every SELECT
run through the Django ORM (and possibly INSERT/UPDATE/DELETE) is
running a com_admin_command. Running queries separately on MySQL or
through connection.cursor() do not cause this.
For example:
from django.contrib.auth.models import User
u = User.objects.get(pk=1)
will cause an increase in com_admin_commands but not
from django.db import connection
c=connection.cursor()
c.execute("select * from auth_user")
I have 3 questions:
1) Have other django/mysql developers encountered this?
2) Have they encountered perfomance issues as a result ?
3) Which command (if any) is being fired to cause an increase in
com_admin_commands ?

newbie help
Hello all,
I'm following the Django tutorial [1] I'm using windows xp, python 2.5 and
SQLite. For some reason I found these 2 things not being appropiate as followed
in the tutorial:
1) When tried "python manage.py sql polls" I got this
TypeError: __init__() got an unexpected keyword argument 'max_length'.
I could only run it successfully by changing the linea
question = models.CharField(max_length=200)
to
question = models.CharField(maxlength=200)
(stripped off the undrescore in "max_length")
2) Continuing down to the "Playing with the API" section, and once I saved some
poll objects to the DB, etc I executed the following command as specified in
the tutorial:
Poll.objects.all()
For some reason, the result I get from the shell is
>>> Poll.objects.all()
[]
Even when I inserted the __unicode__() method in models.py as follows:
class Poll(models.Model):
question = models.CharField(maxlength=200)
pub_date = models.DateTimeField('date published')
def __unicode__(self):
return self.question
Anything I'm doing wrong?
Thanks a lot

writing unit tests for views?
Writing tests for models has been a snap, but I'm having a lot harder
time with the views.
I'm trying to use the test client, something like this:
from django.test import Client, TestCase
class ViewTest(TestCase):
def setUp(self):
self.client = Client()
def test_view_profile(self):
response = self.client.get('/accounts/profile/', {'username':
'newuser1'})
# Check some response details
self.assertEqual(response.status_code, 200)
self.assertContains(response, 'Profile View')
But I'm getting errors related to the project settings, most
specifically this one:
File "/Users/bshaurette/Code/django_trunk/django/core/handlers/
base.py", line 126, in get_response
subject = 'Error (%s IP): %s' % ((request.META.get('REMOTE_ADDR')
in settings.INTERNAL_IPS and 'internal' or 'EXTERNAL'), request.path)
TypeError: 'in ' requires string as left operand
I tried setting an INTERNAL_IPS value to get around that, but there
are other settings errors that pop up. Ultimately, it looks like the
test is having trouble reconciling paths between the project urls.py
and the app urls.py ... ?
DoesNotExist: Site matching query does not exist.
I'm not new to writing tests, just to unit testing in Django/Python -
what would *really* help is if I could see some other examples of view
testing. I feel like I've been banging my head against a wall for a
few days now. Has anyone got any recommendations?

Missing Records in Admin Interface [SOLVED]
I had an interesting problem today. I had some records that were missing in the auto-admin list of one of my models. The count was correct, but the records were simply not displayed. When I did a select query from the command line they all showed up just fine; some of them were simply missing from the auto- admin list. I finally isolated the problem to a missing record a couple of foreign key hops away. For example... Project1 <-- Product1 <-- Model1 (visible) Project2 (not created) <-- Product2 <-- Model2 (missing) So Model2 wasn't being displayed because Project2 didn't exist. I think this had something to do with my unicode method on the Product because I referenced the Project in it. It was probably throwing an error, but for some reason Django was just ignoring it. In any case, I hope this helps someone. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: newbie help
maxlength was changed in the trunk to max_length. You are probably using
an older version of Django, the tutorial you were following refers to
the latest version:
http://code.djangoproject.com/ticket/6457
As for the returning the text thing, same deal. If you go to this page:
http://www.djangoproject.com/documentation/tutorial01/ and look at where
it explains to do that, it has a little note below it explaining that
this wil happen in the older version.
If i were you, I'd either upgrade your Django, or start following the
0.96 tutorial from here.

com_admin_commands includes COM_PING, which is issued every time the MySQL
backend is called to retrieve a cursor for an existing connection.
Internally it looks like Django gets a cursor pretty much immediately before
executing any SQL. So any hit to the database (after the connection is
first established) is probably incrementing con_admin_commands.

If you try this 2nd sequence multiple times, you will see that the
connection.cursor() call causes an increment of com_admin_commands (it does
not the first time because during that call a connection is established).
Django internally does the connection.cursor() immediately before each
execute(), so com_admin_commands gets incremented a lot.

Yes, I see the same behavior. Whether doing this ping before each SQL
execute is a significnat performance hit I don't know. It seems a bit
wasteful, but the time involved could easily be just noise compared to the
time required for real work that has to get done for each SQL execute.
You'd need to get some profiling data or experiment with removing it to see
what its measurable cost is.

Multi-level template blocks
I'm new to Django, and I'm struggling with something that seems to be
do-able. Maybe I'm thinking about the problem wrong. Help?
I'm converting an application from hand-constructed Python that builds
a large web site to Django templates. The site has multiple layers.
All pages share the same basic layout, header, footer, etc. On each
intermediate layer, some features are added, but there are several
flavors of page within each layer. I thought I could arrange it as
follows:
base.html
-
{{title}}
Header Stuff
{%block contents%}{%endblock%}
Footer Stuff
-
layer1.html
-
{%extends base.html%}
{%block contents%}
Layer One has cool {{noun}}.
{%block layer_special%}More layer specialization here, that will be
filled in later.{%endblock%}
Layer One closing stuff.
{%endblock%}
-
layer1-special1.html
-
{%extents layer1.html%}
{%block layer_specials%}
You need more than {{noun}}. You can be special. Sometime you gotta
{{verb}}.
{%endblock%}
-
In Python:
from django.template import Context, Template, loader
t = loader.get_template("layer1-special1.html")
c = Context( { "title":"Layer One Special One", "noun":"Stuff",
"verb":"Django" } )
print t.render(c)
should print:
Layer One Special One
Header Stuff
Layer One has cool Stuff.
You need more than Stuff. You can be special. Sometime you gotta
Django.
Layer One closing stuff.
Footer Stuff
But Django gets an error when it tries to parse the template. The
error is "django.template.TemplateSyntaxError: Invalid block tag:
'endblock' ".
This is a simple sample, there are at least three different "layers",
and each layer has between 3 and 5 different "specializations". At
each level there is significant added html and django code, and I'm a
big believer in only doing something once and not duplicating code.
Help?

Re: .pyc files not being created
> Hi Malcom, > > Thanks a lot for the detailed response. > > Sorry if these are basic questions but, what user would my web server > be run under (Apache2)? Would it be my username, root, or something > else like "apache"? Probably nobody or www. A simple way to try and find out is using 'ps axu | grep httpd'; the first column should give you the user (I don't have access to an Ubuntu distribution, otherwise I could tell you straight away; but Google or the Ubuntu website can also tell you I guess). Of course, you can always use root to compile .py files, that'll "bypass" permissions; but see Malcom's comments. > Would I have to run compileall.py every time I change a source file > (it seems like I would have to)? Possibly, but you'd only want to serve files through apache + mod_python that aren't going to change much (eg, Django, although that should just live in the Python site-packages dir); every change also involves restarting apache for example. Better to sort everything out using the dev-server, then copy files and run compileall. You'd then only run compileall for (major) upgrades; not for every single source file change. > I couldn't get compileall.py to work on the command line... Tried > 'compileall.py' and 'compileall'. What am I doing wrong? compileall comes with the Python source distribution, which is probably hidden away in a tar file on your server, if anywhere at all. If your database is working, try a 'locate compileall.py' Otherwise, if it's not there, grep a Python source distribution (preferably one that agrees with your Python version) and use the one included with that. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

ANNOUNCE: Django search with Lucene.
Hi, django users and developers.
I'm happy to let you know my django application, Django search with
Lucene(DSL). I try
to tighly integrate the Lucene with Django, so I find the way to use
lucene easily in Django.
Django search with Lucene(DSL) supports,
* indexing object automatically when object is saved(update, delete
also applied in index)
* search indexed document by django filtering expression
>>> Person.objects_search.filter(name="spike", age=10)
* indexing the existing object like this,
>>> Person.objects.filter(pk__gte=100).create_index()
* etc.
Make a story short, this is examples,
===
person = Person.objects.create(
name_first="Spike",
name_last="Ekips",
)
person.name_first = "New Spike"
person.name_last = "New Ekips"
person.save()
>>> Person.objects.objects_search(name_first="Spike").exclude(name_last="ekips").order_by("-time_added")
>>> Person.objects_search(name_first__icontains="pike").order_by("-time_added")
>>> Person..objects_search(
time_added__lte=(datetime.datetime.now() -
datetime.timedelta(days=10))
)
>>> result = Person.objects_search(
time_added__lte=(datetime.datetime.now() -
datetime.timedelta(days=10))
)
>>> for i in result :
print i.get("name_first")
print i.name_first
print i.pk
print i.get("__uid__")
print i.get("name_last")
===
object automatically indexed when saved and analyzed and we can digg
the index db with django model filtering expression.
For more information, visit the project page,
http://code.google.com/p/django-search-lucene/
or see the short document at
http://django-search-lucene.googlecode.com/files/django-search-lucene.pdf

Modules Imported Multiple Times
Hi, I'm having a problem where Python modules are being imported multiple times and I cannot figure out why. I have a simple, standard set up created with the following commands: django-admin.py startproject mytest cd mytest manage.py startapp app1 I would like to run some initialization code before manage.py runs execute_manager() and some uninitialization after it is done: if __name__ == "__main__": import app1 app1.init() execute_manager(settings) app1.uninit() Unfortunately, app1/__init__.py gets loaded both here with the "import app1" line and also imported later when app1 is initialized by the framework. Has anyone else experienced this problem? Is there a way to fix this? Environment: * Python 2.5.2 * Ubuntu 8.04 * Django 0.96.2 Thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Pylucen in thread must
import PyLucene.PythonThread as thread。
have you test it for fcgi?
