Django doesnt create sqlite database
Hi Buddy, I am newbie in Django. Recently I try out the Django tutorial from web with python 2.5.2 and sqlite3 Unfortunately, Django doesn't create sqlite database as the tutorial stated. And I couldn't find any FAQ on the web. Could you advise me on this? Thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Add Request Parameters
I'm writing some code that does something like...
1. check url for specific information
2. do some logic based on named group
3. pass results along on request
It is easy for me to do this through urls.py for a single request.
However, i want to perform this for every request.
I am going down the path of creating a custom middleware that will
perform my logic as mentioned.
My problem is with how to pass the results along on the request.
My intuition is to try and add a parameter like so...
q = request.GET.copy();
q.__setitem__('new_key', 'new_val')
request.GET = q
Only problem is that the code further down the pipe doesn't recognize
'new_key' as being available in the request.GET querydict.
please advise.
thanks.

More than likely you have some order dependency in way things are loaded into memory by your Django application. You should post the exact traceback from the error logs so that people can at least attempt to resolve what is likely your real problem rather than just assume that changing hosting mechanisms will help. > What do u guys recommend for a most effective and stable Django set up > options on a production server?

[Weird server issues] Most effective and stable Django set up on a production server?
Hi all, as per the subject: what is the most effective and stable Django set up options on a production server? I am currently on a mod_python, linux, apache set up. And sometimes, it seems that the server is unstable. For example, whenever i try to submit a form ( uploading images ), there are times where it says that there is an error ( template not found ), and times where the upload was successful. ( the code running on my local computer runs perfectly) Is that due to unstable server?

python manage.py syncdb error: sqlite3.OperationalError: unable to open database file
Hello hey michael I have been experiencing this problem since I installed my brand new Ubuntu Karmic with python in version 2.6 The project I am working on was working under python2.5 in my old Gentoo and still works (at least the python manage.py syncdb command does) on a server which is also running python2.5. I have tried installing both the latest official version and the latest development version of django and still the "python manage.py syncdb" it returns this error: Traceback (most recent call last): File "manage.py", line 11, in execute_manager(settings) File "/usr/local/lib/python2.6/dist-packages/django/core/management/ __init__.py", line 3 utility.execute() File "/usr/local/lib/python2.6/dist-packages/django/core/management/ __init__.py", line 3 self.fetch_command(subcommand).run_from_argv(self.argv) File "/usr/local/lib/python2.6/dist-packages/django/core/management/ base.py", line 195, self.execute(*args, **options.__dict__) File "/usr/local/lib/python2.6/dist-packages/django/core/management/ base.py", line 222, output = self.handle(*args, **options) File "/usr/local/lib/python2.6/dist-packages/django/core/management/ base.py", line 351, return self.handle_noargs(**options) File "/usr/local/lib/python2.6/dist-packages/django/core/management/ commands/syncdb.py", cursor = connection.cursor() File "/usr/local/lib/python2.6/dist-packages/django/db/backends/ __init__.py", line 81, i cursor = self._cursor() File "/usr/local/lib/python2.6/dist-packages/django/db/backends/ sqlite3/base.py", line 1 self.connection = Database.connect(**kwargs) sqlite3.OperationalError: unable to open database file i have looked at other posts and the majority of people had the"operational error" caused by "~" in the path to the main folder in the settings.py or permissions to write for the folder that contains the project. none of the advices i found solved my problem. do you have any idea where this comes from and what should i do? is there something to be set in sqlite or should i modify django's destinations/target files? thanks selena --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I agree 100%. On this project (and some I've worked on before) I know I'll be adding fields as it becomes apparent I'll need them. And I know even with some great schema planning I'll still be adding fields well after the test data for those models is in place. > > I tend to start with the models first and when I add a field, I just use alter > to update the table in place.

The biggest one is that if you decide later to add a field to the model that isn't there and you've filled in some data to the db. Syncdb is ineffective at updating the table so you either drop the table and reload the data as a fixture with the added field data, or start again with data or use a db migration tool like django evolution. I tend to start with the models first and when I add a field, I just use alter to update the table in place. This has a gotcha with NOT NULL though, if you don't specify a default you'll end up with an error. To bypass this error, I usually don't add the NOT NULL constraint till after I've added the field and updated the existing rows with the required data. This may not be the best approach to it, but it works for me and is fast enough and requires less prep time for using such tools as evolution and the like (no need to install or learn them) and/or editting fixtures.

Re: "django-pagination" and generic.views.date_based.archive_index()
Sorry, didn't look at condition well...:(
So, you see the source and you see that there's no way to get all the
records with this view.
Why don't you use list_detail.object_list view? If you need just to order
list by date, you can use ordering on the model level:

Re: "django-pagination" and generic.views.date_based.archive_index()
Would it? If "latest=None" doesn't it mean that there are no entries?
By the way, if I pass None to the condition, it returns False, so
latest is None.
Or isn't it?
Also the template cannot render it, cause "object of type 'NoneType'
has no len()".
Anyways, thanks for reply :)

Re: "django-pagination" and generic.views.date_based.archive_index()
Look at date_based.py:
if date_list and num_latest:
latest = queryset.order_by('-'+date_field)[:num_latest]
else:
latest = None
So, if you use num_latest=None, you will always get the whole list.

Django production set up woes [Please Help]
Hi all, The environment i am using to set up my django project/app on a production server is as follows: Ubuntu 9.04, Django 1.02, Python version 2.6.2. Mysql, mysqldb, apache2 and php is all set up and good to go. I have followed the tutorial at http://jeffbaier.com/articles/installing-django-on-an-ubuntu-linux-server/ for setting Django and it worked ok. I named the project as the same name for my django project on my development computer. I got the Django error message since i have not done anything yet when i visited the ip address. Which means that my installation were ok. Next i created an app ( on the production server ) as per the name i have named on my development computer. After which i uploaded alllmy django projct/app files to the production server using the terminal. Here's where the nightmare happens: After i have copied all my django project files to the production server, and tested the application on the production server, only the homepage worked. Whenever i tried to visit other pages to test it out, i received the error : Exception Type: ViewDoesNotExist However, the problem is that i have already started the app in the production server before i upload all my files onto the project itself. May i know how do i fix this problem? Best Regards, Eugene --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Whops. request.GET is a query dict, so it's of course not callable. I
ment to call get('user_text', '') on the request.GET:
request.GET.get('user_text', '')

Problem with filter_horizontal
Hi,
This is my first django app and I can't seem to get filter_horizontal to
work correctly. I've seen other people asking about this but I don't see any
answers in an hour of searching. Can anybody give me some insight into what
I'm doing wrong? Right now when I use Admin to create a document I get a
select box that just says Tags Object. So there's two things I'd like help
with if possible.
1) Am I using filter_horizontal correctly? If not, what am I doing wrong?
2) If I don't use filter_horizontal, how do I get the items in the select box
to say the name of the of the Tag rather than say Tags Object?
Some info about my environment. I'm using Django 1.1.1, python 2.5, Apache,
and I've tested on IE, Firefox, and Chrome. My admin seems to work otherwise.
Thanks in advance for any help.
class Tags(models.Model):
tagname = models.CharField(max_length=40, primary_key=True)
class Document(models.Model):
name = models.CharField(max_length=40)
location = models.FileField(upload_to='repository')
indexed = models.BooleanField(('indexed'), default=False)
tag= models.ManyToManyField(Tags)
class TagsAdmin(admin.ModelAdmin):
list_display = ('tagname',)
class DocumentAdmin(admin.ModelAdmin):
list_display = ('name', 'indexed',)
filter_horizontal = ('tag',)
admin.site.register(Tags, TagsAdmin)
admin.site.register(Document, DocumentAdmin)

Re: form problem
First of all may I recommend you to use Django forms:
http://docs.djangoproject.com/en/dev/topics/forms/
> With this method i have the following error:
> Key 'user_text' not found in
>> def view(request):

When requesting the view for the first time the request.GET dict will
not contain a 'user_text'. If you replace request.GET['user_text'] by
request.GET('user_text', '') it will not raise an exception, but return
'' (empty string) if no 'user_text' is contained in the GET dict.
Besides it's good practice to use POST for forms, if they're used to
submit new or modify existing data. That's the reason why the example
code in the forms documentation always checks for request.method ==
'POST' to see if the form is actually being submitted or loaded for the
first time.
In order to get the idea of POST and GET better you might be best of
googeling for it and reading up what the HTTP methods are supposted to
be used for. Rule of thumb: Use POST whenever you're modifying data and
GET when querying data.

As far as I'm concerned - and given I have at least a rough functional spec (but I fail to see how one could write any piece of software with functional specs...) - models are of course the starting point. And models that are not only dumb data-holders - most of the "operations" on models should be handled by the models and managers themselves, not by the views. Views are only an interface between the users and the models, not a place to fill with business rules and 'low-level' operations. FWIW, I don't even bother with views or urls before I have a first working implementation of my models (remember you can test your models from the interactive shell and/or python scripts). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Ah.. but there's the rub - it _did_ run all the test cases in
ArticlesPaginationTestCase :-)
The point of confusion is that there are no tests in
ArticlesPaginationTestCase - at least, not according to the criteria
of unittest.TestCase. TestCase requires that test functions _must_
have a name starting with "test" - thats how it automatically
discovers the test cases.
So, from the point of view of unittest.TestCase:
class ArticleTestCase(TestCase):
def test_index(self):
...
def test_index_default_list(self):
...
contains two tests, but:
class ArticlePaginationTestCase(TestCase):
def default_num_per_page(self):
...
def first_set_has_next(self):
...
contains no tests - it just contains two utility methods.
When you explicitly name the test on the command line, you work around
the problem. Since no automatic discovery is required, the prefix
isn't strictly required, and so the test can run. If you want unittest
to discover the tests automatically, just rename the test cases and
prepend the "test" prefix.
This isn't something unique to Django - it's a common feature of all
the xUnit family of APIs.

Russ Magee %-)k

Re: Problem in installing database adapter.
I don't remember how I installed it (mysqldb or python-mysqldb), but assuming that this is the correct module, then it's possible that it's for different Python version that you are actually using. For example, default Python for Ubuntu 8 is, iirc, 2.5.2, while you might be using 2.4 or 2.6 for your development. If this is the case, then you can try easy_install for your version of Python, again iirc (writing out of my head), it could be as simple as easy_install2.6 mysqldb -- Tomasz Zielinski, http://pyconsultant.eu --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: How to restrict True value to only one row in table column
Maybe you can use something like this: http://stackoverflow.com/questions/1346765/unique-constraint-that-allows-empty-values-in-mysql This would probably mean converting is_master to: is_master = models.BooleanField(null=True, blank=True, unique=True) - and possibly overriding save to convert accidental False-s to None- s. Other solution would be to store somewhere (possibly in separate model with single instance) separate value: which_Thing_is_master Just some quick ideas. -- Tomasz Zielinski http://pyconsultant.eu --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django methodologies and best practices
It surely depends on your input. If you have detailed specification of user interface, then writing URLconfs is probably more or less no- brainer, and also the design can often be quite obvious. On the other hand, if you're starting in 'fluid' environment and project doesn't have a direction, then you're forced to start with one view and evolve design. Re templates - it depends on whether you receive them from you customer or only know some general requirements and have to improvise until some consensus is reached. So, if you ask me, then there is no single answer to your questions. If you want to get more precise answer then you have to provide some more insight into your problem. -- Tomasz Zielinski http://pyconsultant.eu --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Hi all, Let's say I have a model like so: class Thing(models.Model): is_master = models.BooleanField() name = models.CharField() Now I want to be sure that only one Thing is_master at any given time. The rest of the Things must not be master and end users shouldn't be able to make a sencond Thing master by mistake through the admin site.

I'm not saying this is best and most scalable way but we're doing SaaS Django projects and it's project per customer.
