multi_db support for doctests? How to enable?
Hi, http://docs.djangoproject.com/en/dev/topics/testing/#multi-database-support tells me to add "multi_db = True" to my unittest TestCase class to get multi db support. I'm using a doctest, however, and I can't figure out how to set that for my doctest. Anyone know how to get that working? My tests.py looks like this: === import doctest import unittest def suite(): """Return test suite This method is automatically called by django's test mechanism. """ suite = unittest.TestSuite() doctests = doctest.DocFileSuite( 'USAGE.txt', 'models.txt', module_relative=True, optionflags=(doctest.NORMALIZE_WHITESPACE | doctest.ELLIPSIS | doctest.REPORT_NDIFF)) # Multi db hack, I cannot set the multi_db to true otherwise. for test in doctests._tests: test.multi_db = True # End of hack, which doesn't work anyway... suite.addTest(doctests) return suite = Reinout -- Reinout van Rees - rein...@vanrees.org - http://reinout.vanrees.org Programmer at http://www.nelen-schuurmans.nl "Military engineers build missiles.

Ah, ok.
Then I'm doing something else wrong (I've only got doctests right now):
my second database isn't created by the test mechanism. I added a
regular unittest with the multi_db=True, but that also didn't result in
a second database.
The code *does* use the regular database (sqlite, if available), but it
doesn't create a test database like it does for the default database.
The relevant part from my testsettings.py:
DATABASES = {
'default': {
'ENGINE': 'django.contrib.gis.db.backends.spatialite',
'NAME': 'test.db',
},
'fews-unblobbed': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': 'testunblobbed.db',
}
}
No special options, I'd say. The test database *used* to get created
when I last ran the tests a few weeks ago, now that I think about it.
I'll have to do some more debugging.

Which patch/ticket is that? With my router, the second database is definitively not filled with all tables: just the 5 that are supposed to be in there.

I must say I haven't used doctests with multidb yet. Also I'm not sure I understood your issue correctly. When you state that the second database isn't created, you mean the tables are not created right ? Yes, the tables aren't created. I found it, sigh. I added the following lines to my settings.py according to one of those django-with-hudson-integration articles (like http://www.caktusgroup.com/blog/2010/03/08/django-and-hudson-ci-day-1/): TEST_RUNNER = 'xmlrunner.extra.djangotestrunner.run_tests' TEST_OUTPUT_DESCRIPTIONS = True TEST_OUTPUT_DIR = 'xmlrunner' Apparently that test runner doesn't work with the multi db setup. When I removed those lines, the tests would work again. I really should have spotted that by running the tests before and after making that config change...

I try to make my apps portable between the various sites/projects that

In a nutshell, I've got multiple sites/projects, and I'd like them to
all use the same articles app. Problem is, the articles app was
originally written for site A,and has at least one M2M relationship
with another app that site B does not have, need, or really want. So,
how do I give site A what it needs without cluttering up Site B with a
bunch of unwanted extras, while using the same app?
Can you write the articles app without the functionality needed by A but
not B? You could have site A handle the M2M relationship to that other
app, probably.
The M2M relation probably results in a couple of extra links in the web
interface, right? Have a generic template in the articles app and
override it in site A. Could work.
Another thing to think of: the view method for the articles? Allow a
couple of optional keyword arguments ("extra_relation=other_app_thingy")
for things that need customizing for the various sites.

From http://docs.djangoproject.com/en/dev/ref/contrib/csrf/ :
In any template that uses a POST form, use the csrf_token tag

But now I need a more solid way to deploy those files, without concerning about symlinks I need to make after libraries install. What solution do you use? Apache aliases?

It would be very nice to pack a library (like, for example, filebrowser), and have python unpack it on cache and serve also javascript and image files. Is it possible? Yes, it is :-) Django-staticfiles is an application that can do it for you. In DEBUG mode, django-staticfiles handles those files for you directly. DEBUG=False, so in production: the "manage.py build_static" grabs all your media files and puts them in a directory, ready for apache to serve. Behind the scenes, you have to have a /media directory in your applications, just like that /template directory that's already there. It basically works in the same way.

I'm not sure if it's what you want, but... I've got a base ui
application with a ui/base.html. Several blocks for the title, logo,
the sidebar, footer, javascript, etc.
Several applications extend that base template. But multiple sites also
want to extend it to change the global logo and footer... The sites
effectively have to override the base template.
The solution: in my ui project I have a ui/realbase.html that is
extended by ui/base.html. The only code in ui/base.html is the
"extends" line! So overriding that one is inexpensive.
The other applications can happily extend ui/base.html and fill in the
blocks that are really from ui/realbase.html. And my site can override
ui/base.html and fill in the logo block and the footer block (which are
normally not touched by the applications).
I hope I'm clear enough without a code example. The code, should you
want to take a look, is at http://pypi.python.org/pypi/lizard-ui

But I cannot find a windows installer for that. Either I'm blind or nobody uses oracle+geo stuff on windows :-) a) Do I really need that geos library? Or could there be something wrong with the oracle installation (like missing geo templates whatever). b) Where can I grab a windows installer for GEOS?

Re: manage.py syncdb not working

It says there are no fixtures found even after I just added a field to a model. No fixtures found: it means to tell you that it didn't find any special-named "initial_data" fixtures. Regular fixtures must/can be loaded with "manage.py loaddata fixturename". A solution has been to drop the table in MySQL before running syncdb. This doesn't seem feasible all the time. What could I be doing wrong? It is a (sensible) restriction of syncdb: it only creates missing tables. If you modified a table, the table is still there, so it won't re-add it. Doing so would mean potential data corruption. So if you added fields to a model, you'll have to add that field by hand to the table. An alternative is for instance South (http://south.aeracode.org/) which *can* do the database migration for you, also in the case of added fields.

You could also attempt it the other way around.
If I remember correctly, they added a "dummy" {% csrf %} tag to 1.1.x
that doesn't really do anything. So a form that works with 1.2 also
works with 1.1 without throwing errors.
You could see if that's available/portable for 1.0, too. Otherwise, a

I'd put a slash in front of "media".

I only recently started using geodjango, so I'll just spit out a few brainstormy ideas without any real solution: - What's the coordinate system of your user's location data? - Why transforming before grabbing the distance? Can't you transform afterwards? - If you're using the google projection somewhere: did you add it to your geo database? There's a note somewhere in geodjango's doc about that 900973 projection. Not having it could throw off a calculation. - There's also a hint in that doc about a NULL projection that you need to add to your proj4 or whatever files to enable proper transformations.

multiple oracle database queries in one request problem
Hi, I'm deploying a site on windows with oracle (and I don't know either of them well). Simple apache+wsgi setup for now. Problem: one specific page kills off the mod_wsgi/django part. The rest of apache keeps working. "Kill off" meaning "it doesn't react anymore and takes quite some time for apache to kill it when I close apache. The only error message I can find is an "errno 10054" "existing connection was forcibly closed". I can only guess that the remote database server closed something. The specific page is the only one that fires off queries to both databases, so within the same request. Anyone got any hints on where to look? How to debug? How to fix it?

I'll have to test it out tomorrow when I'm near the windows machine
again, but I might have found the solution in an existing bug report:
http://code.djangoproject.com/ticket/13351
In a threaded situation (which you always have with mod_wsgi on
windows), you apparently need to pass the cx_oracle database driver a
threaded=True option (which is off by default).
So I added the following to my database config and I'm hoping I'll be
happy tomorrow morning...
'OPTIONS': {'threaded': True}
I'll update the ticket when it helps.

That did not help... If anything, it crashes earlier.
Some things I know for (reasonably) sure:
- It occurs when running with threads: mod_wsgi on windows.
- It occurs when talking to the oracle database.
- It occurs when I talk to two databases on the same oracle server
(well, that's database in django speak, oracle calls it a schema: it is
in the same physical oracle-speak database).
So I'm desperately trying to figure out how to tell mod_wsgi to run in
single threaded mode for the time being. The problem is that only
WSGIDaemonProcess has the required "threads=1" option and exactly that
WSGIDaemonProcess isn't available on windows! Catch 22.

Now I seem to have a utils problem??
Sorry, no solution. Frustrated rant below, perhaps it helps yo uto know
that you're not alone... :-)
Windows, I guess? I have never ever seen this problem under linux. But
I've been bashing my head on a windows install problem for a full week.
(Well, a 80 hour week instead of the regular 40 hour week).
I could not solve the postgres problem. Paths all seemed OK. The
relevant postres stuff is installed globally. So both apache (mod_wsgi)
and "runserver" should be able to find it. But apache fails to find it.
No way to debug as I've got no windows experience. Everything looks
right.
"Luckily" the oracle driver (it was supposed to connect to an oracle db
after all) did work OK. At least, until you talked to a certain
database in multi-treaded mode. Telling (via OPTIONS={'threaded':True}
in the database settings) it to run in multi-treaded mode didn't help.
Something somewhere (no error messages) kept crashing. I dived into
a couple of the python libraries (pdb and so), but I couldn't check
every detail. And the c-level libraries were beyond me.
In the end I got it working (that is, "not actively dying") by telling
apache to run with just one single thread... That's some solution...
This is the first time that a hard problem took more than 1.5 day to
fix. Effectively, this is 2 full work weeks. And still no real solution.

It is already on the first go into your view that Django complains about
a missing CSRF token. It won't even hit your "else add csrf token" code.
The solution is simple: just add a {{ csrf_token }} somewhere in your
form. That ought to do it.

That the syslog ends up with this info probably means that django prints it out on the console, which would normally end up in your apache's error log. Probably you configured apache to send it to the syslog instead. Printing on the console means "print ..." or a logger that's configured to print to the console. Did you do the latter? My guess: someone put a print statement in django/contrib/sessions/middleware.py for debug purposes. So check the django that your site is using and see if you have to beat someone with a stout stick.

You can install matplotlib just fine in your virtualenv, but with one prerequisite: all necessary libraries and header files must be available for pip to be able to compile matplotlib. This compiling-and-grabbing-headers stuff is already handled for you by your OS and now you'll have to do it yourself. Which is fine, but it *does* mean you must have all xyz-devel packages installed. An alternative is to keep your global python clean and only install specific packages with your OS that are best handled by the OS. Don't "pip install" other stuff by hand.

Re: philosophy behind sites and applications in Django

Hi guys, I'm new in Django (I started with the 1.3 and now I'm playing
with the 1.4) and I'd like to understand better the phylosophy behind
the concepts of sites and applications.
Ok a site can contain multiple applications and an application can live
in many sites, that's simple.
Now.
For me a site is like a "container" of applications and every
application accomplish a particular job just like manage polls, articles
and so on. But a site must have its own graphic style, and in particular
common parts, just like user management.
How do you handle these "trasversal" (common) components?
For example, is it possible to define a css at site level? How to deal
with user management and other commont funcionalities?
You're right, a site is a container of applications and an application
should do one thing and one thing only.
Normally, you don't want your site to contain applications and at the
same time have those applications inherit from your site's main template
or so.
But... django sticks all the templates/ and static/ directories of all
apps and sites together. So nothing stops you from sticking a very basic
base template in every app ("yourapp/templates/base.html") with just a
sidebar and main content block or so. You can have your apps use that.
In your site, you provide the real "yoursite/templates/base.html", which
will win because your site is higher up in the INSTALLED_APPS list.
Stuff that one full with the real layout and css, but keep providing the
sidebar and content block (or whatever you need).
Alternative: just make templates in the apps and customize them in the
site. Not as nice imho.
ALternative: start a base UI app that just provides a layout. Use that
in the apps.

Yes: You have to call user.save() after creating it. Otherwise the user
object exists, but it isn't saved to the database yet. And
"self.client.login()" queries the database, not user objects local to
the test.
Creating model objects in tests and testing them afterwards is something
that needs a bit of care. I've made several mistakes with them already

Re: buildout development vs. deployment
On 25-04-12 12:21, Reikje wrote:
Hi, I am looking into buildout to deploy a django webapp and all it's
dependencies. I find it quite useful even during development because it
forces you to keep track of your dependencies. A question regarding some
best practices. Lets say I have buildout.cfg and setup.py in my project
root and checked in into SCM. My webapp is listed under develop in
buildout.cfg. While this is great, during deployment this is probably
not what you want because you wanna lock the version of your source
code. I want to do a git revision checkout to archive this. So i guess I
need to maintain two different buildout.cfg files, one for development
and one for deployment. How can this be organized to avoid DRY?
I have a production.cfg that extends buildout.cfg. I can then add extra
parts ("set up a supervisord to run gunicorn") of modify settings in
existing ones ("use port 10026 instead of 8000").
I get to keep it pretty DRY that way.
Note that I make proper packages out of my development apps and stick
them somewhere that buildout can find them. You could try to use the
mr.developer add-on to check out tags of your stuff.
For hints on getting your own packages up on a pypi of your own:
http://reinout.vanrees.org/weblog/2009/11/09/eggproxy-plus-private-packages.html
That ought to give you some hints.
On a side note, what are the alternatives to buildout. Maybe there is
something even better :)
Buildout provides two things:
- Installation + isolation of python packages, just like the
pip+virtualenv environment. With the note that buildout works just fine
on windows and that pip won't install binary windows eggs. Otherwise the
effect is mostly the same, though I like buildout's version handling
better as it is impossible to forget it (unlike forgetting to pass pip a
requirements.txt file).
- Add-on recipes for extra automation. Great for deployment. Generating
nginx/apache config files, setting up a cron job, creating
your_site_dir/var/log directories and so on.
=> for handling everything *within* your project directory, nothing
beats the functionality of buildout. And it combines fine with tools
like fabric that can handle everything outside of the project directory.

My specific question is… Swapping xml output from Django for JSON output should be pretty straightforward, I guess. And you can feed the JSON to your brand new html5+javascript front-end. If you're comfortable with javascript, this could be pretty similar in nature to your current setup. When looking at the Django templating features vs using a tool like CS5.5 or expression blend, what advice would you offer deciding how much to put into the template logic and how much to do via AJAX/Javascript/Jquery? My applications are generally 10 to 30 pages and I have a 10% commonality between applications.

For the near future we're sticking with templates, but with javascript for the spots where we need it (we'll use backbone to clean up on part of the UI). I like the idea of using two different systems from the backend and the frontend. I am new to django (a month+), but I don't think there was ever a doubt in mind that my frontend would be .js based, and I liked that django dev let /static to be dealt with by say plain Apache, instead of enforcing python for that too. And... with django's staticfiles handling you can even bundle js/css/images per app and Django'll combine it all together. Works great. As I said, I am new to django, but I have done some experiments (wrote my own little hello world app, moved on to deploying mezzanine to dotcloud), and as I understand django is meant to be a flexible system to handle data, and was never meant to be a flexible frontend, right? Django has always been frontend-agnostic. There's only the admin interface, for the rest you have to build everything yourself. Now, even though I do like the proper tools for the proper jobs, the perspective of maintaining two systems built on different technologies raises red flags. What do people think? Well, if the separation is clean enough, it is fine. Just make sure you don't tie them together too much.

The solution is simple: Run a separate Django server and tweak your development-only static URL to something like: STATIC_URL = 'http://localhost:8000/site_media/ " but this doesn't works anymore, because django.contrib.staticfiles doesn't serve static when STATIC_URL contains full URL.

Perhaps there's a difference that your first example is a POST to that

Do you have some middleware or so that does something to the request?
Does your view modify the request, inadvertently modifying it into a dict?

You won't need protection against sql injection, for instance, as it is simply not a problem with django. mod_security looks like something that needs both care and knowledge to set up properly. So you yourself will need to gain knowledge on what mod_security actually does and how to configure it.

You're probably right. I don't know the full range of what mod_security protects against. My reaction was more the other side of the coin: don't feel secure "just" because you put mod_security in front if you don't fully know what that protects against and what actually needs protecting in Django.

You're getting the 500 on the image, so you can't easily see the full 500 traceback in your browser as the html renders just fine. Two options: - Just go directly to the url of the image instead of to the html page that contains the img tag. Then you'll see the 500 traceback of your image itself.

Probably all your logging statements are executed right at file import
time before the logging is actually configured.
Just as a simple test, put such a logging statement inside one of your

MYDICT.myform looks up an 'myform' attribute on MYDICT or the 'myform'

There's no way the template language can know that it first has to look
up the last three items and then apply that to the first item. That's
the basic problem.
Best solution probably: just do the MYDICT[myform.somefield.value] in
your view and pass the value to the template?
