ANN: workaround for MySQLdb upgrade problems

[Malcolm Tredinnick]

All,

Understanding that not everybody is in a position to immediately upgrade
their version of MySQLdb to the required 1.2.1p2 upon release of 0.96,
we have now committed a backwards-compatible MySQL backend to the
repository. This is called mysql_old.

If you really, really cannot upgrade the MySQLdb you are running against
and are willing to accept the problems caused by using the older
version, replace the mysql backend setting in settings.py with
'mysql_old' and everything should work as before.

It is important to realise:

- This backend is instantly deprecated. It is only a support
measure in order to give people time to upgrade. It will be
removed in a future release.

- This backend will not be actively developed. The only changes
we will make to it will be necessary security fixes, as per our
security policy. It will not necessarily support all the options
and functionality that the 'mysql' backend supports,
particularly in the development period following the 0.96
release.

Hopefully this will provide affected users with a less painful upgrade
path to a supported version.

Regards,
Malcolm

urlconf is actually one of my favorite features.  It's been months

admin, of course.

syndication and sitemap.

one thing that you cannot overemphasise is that django is just  
python. Many people forget this. You can write practially any code  
whatsoever in python and put it in the view - yes, even something  
like programming your electric toaster through the usb port and  
controlling through django over the web

informing user about unsaved fields in overridden save method (in admin)

[Evren Esat Ozkan]

Hi,

I'm checking a field's value againts related object and deciding
saving or not.
But I can't a way to inform user about save state.
Searched  for way of "redirecting to error page" or "passing custom
error messages to admin templates" but found nothing.
(custom valitador is useless because field_data is not paired with
object id)

Any help would be greatly appreciated,

Thanks,

Suggestions for Django Presentation

[Scott Paul Robertson]

I'm giving a presentation on Django to two local Linux Users Groups in
the next month. I don't want to rehash the tutorial; I'd rather spend
time showing off why Django is cool and how to do interesting things
with it. Currently I want to talk about:
- Authenticate framework
- Generic views
- Template language
- Newforms

I'm looking for suggestions of more features to emphasize/show-off. So
what does everyone think? What features make Django such a great
framework?

Thanks,
Scott

PS. If anyone is wondering, the groups are the Provo Linux Users Group
and the BYU Unix Users Group, in Utah, and I'm presenting on April 11th
and 12th, respectively.

djschemadiff - show differences between Django database schemas

[Sam Morris]

Tired of manually updating your database schema after changing your
model classes? So was I! I wrote a tool called djschemadiff to
automatically compare your database's current schema to the schema that
would be produced if you started with a fresh, empty database and then
ran syncdb.

Currently it works with PostgreSQL 8.1, but shouldn't be too hard to
extend to work with other database systems.

djschemadiff can be downloaded from
. Feel free to send me any
comments, flames or patches!

Problem importing models in custom data import scripts

[Nathan Harmston]

Hi Guys and Gals,

I am currently trying to import a large amount of data held in flatfiles
into a database so that it can be displayed through Django. I am using the
most recent development version of Django. I found that a new method called
get_or_create, however I cant seem to get it to work as I cant import the
models file into my Parser script.

My Project is called pynomics and the app alignments.
~/pynomics/alignments/models.py

so in my "Parser.py", I try to import the models file
from pynomics.alignments.models import *

but I get the following error when I try to run it:
Traceback (most recent call last):
  File "Parser.py", line 1, in ?
from pynomics.pyalignments.models import Interval
ImportError: No module named pynomics.pyalignments.models

However the import seems to work when I import it in views.py. Does anyone
know what is wrong with my setup and how to fix it?

Many Thanks in advance

Nathan

Thanks Caz, this makes sense and it's confirmed by the fact that
uploading a non binary file didn't produce any beep even having the
print statement.

I've removed the print statement now and everything is fine ;-)

Thanks a lot,

Mod_python + MySQLdb won't install ...

[dbee]

System: Linux 2.6.9-34.0.1.EL #1 Wed May 24 07:40:56 CDT 2006 i686
athlon i386 GNU/Linux
OS: CentOS
Python: 2.3.4
Mysql: 5.0

I'm having lots of issues trying to get my django server up. It seems
that mod_python won't work on my system.

When I yum install mysql-python, the package installs fine, but I get
this error whenever I need to import it into my python scope.

>>> import MySQLdb
ImportError: this is MySQLdb version (1, 2, 2, 'final', 0), but _mysql
is version (1, 0, 0, 'final', 1)

When I try to build the source version of MySQLdb from sourceforge, it
just errors with this non-descript error...

error: command 'gcc' failed with exit status 1

I really wasn't expecting it to take so long to get mod_python +
MySQLdb working.

Help

No changes relative to 1.2.1 that affect users using MySQL-4.1 or
newer. If you were using MySQL-4.0, 1.2.1 didn't work and you needed
1.2.1p2.

Re: Development in LAN. URLs of FlatPages. Best Practices?

[Aidas Bendoraitis]

> have you found any solution?
Yes. I wrote my own FlatPage model with it's own middleware. Now the
URL can be empty and it represents the relative path counting from the
website root directory. The root directory is "/" on the public site
and "/someproject/" on the development site. The root directory is set
in the settings.

> would it be correct to say that the problem would
> be solved if there was a way to access project settings from inside
> flatpages?
Not really. You don't define what you mean, saying "from inside
faltpages" - whether you're talking about models, views, middleware,
or something else from the flatpages. Anyway, it's enough to write
your own middleware to override the default control of the flatpages
(And fortunately it is not hard to do that).

Which version of Django are you using? 0.95.x or trunk? there was a
problem in 0.95 that caused stuff.search to fail.

Dynamically generated template variables in admin?

[David Zhou]

Hi all,

I'm trying to do something, but before I start, I figure I'll pass it  
on and see if anyone's already done something similar or has a better  
method of accomplishing the same thing.

Let me know if the following sounds feasible or if there's a better  
way of doing it:

Basically, I want to manage my templates in the admin view, and have  
the ability to define custom variables to be filled out.

Then, in say, the "Instance" admin add page, the user is able to  
select a template.  The page will then dymaically generate a table of  
the template variables that need to be filled out along -- like

Title: |==textfield==|
Variable2: |==textfield==|


Live Preview:
|===|
| Preview   |
| of Temp.  |
|===|

I'm thinking that I'll have to edit the admin code somehow, and have  
it parse the selelected template code for {{ variable_title }}.

Then it will use the variable name with underscores replaced with  
spaces as the title.

Should I wait for the new admin code before trying to edit the admin  
interface?

Does this sound like a good way of doing things?

Thanks,

---

Very nice, Alex.  You might consider adding this code
to the djangosnippets.org site.  FWIW, you can replace
the first 4 lines in output_via_template with a single
assignment:

bound_fields = [BoundField(self, field, name) for name, field

Unfortunately, there is a change that we need to worry about: the
thread-safety bug in MySQLdb which caused ticket #3279[1] wasn't fixed
until that version, which is why we now have the version check in

I just downloaded the latest trunk - it reports:

ImproperlyConfigured: Error importing middleware
django.contrib.sessions.middleware: "MySQLdb-1.2.1p2 or newer is

The problem is that the MySQLdb page says that 1.2.1p2 has no changes

ok, this works.

but now I try to make it dynamic and stored the linkinfo to the database..

models.py:

class navigation(models.Model):
 name = models.CharField(maxlength=30)
 link = models.CharField(maxlength=30)
 def __str__(self):
  return self.name

views.py:

# Create your views here.
from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response,get_object_or_404
from django.conf import settings

from mysite.cvh.models import group,navigation

media_root = settings.MEDIA_URL
navi_list = navigation.objects.all()


def index(request):
 return render_to_response('cvh/index.html',
 {
  'media_root' : media_root,
  'navi_list'  : navi_list,
 })

def login(request):
 return render_to_response('cvh/login.html',
 {
  'media_root' : media_root,
  'navi_list'  : navi_list,
 })

template:

  {% block navi %}
  
  {% if navi_list %}
  {% for elem in navi_list %}
   {{elem.name}}
   
  {% endfor %}
  {% else %}
   Index
   Login
  {% endif %}
  
  {% endblock%}
 


The static ELSE statement works. But the database ones don't..
They contain exactly the same content.
the html-output:
 
  
   Index
   
   Login

This problem is already reported as #3212; its on my list of things to
look at. If you want to help out, you can:

1) validate that the patch provided works, and
2) provide a test case (integrated into the Django system tests) to

Question on django.test.client.Client

[[EMAIL PROTECTED]]

Hello everyone,

I have a page with a bunch of select boxes with the same name
("selected") and different values so that they are sent as a list to
the view.  I can't figure how to test multiple selections with
django.test.client.Client however.  This works for a single value:

self.client.post('/foo/', {'selected': '1'})

However, if I want more than one selected boxes, using a list doesn't
work, it simply returns an empty list.  Is it possible to do with
Client or should I open a ticket and start working on a patch?

Vincent

Are you opening a new Python shell (with the myproject.promotions import)
after any of your model/database modifications or have been
maintaining the same shell session open from before you started
these mods?.

If you have a lot of static content, you definitely want to have a
separate server to handle that. Even if it is Apache - just use a
stripped down version (no funky modules) to serve your static data,
and keep the django system separate. All of the Django tutorials
recommend using a separate server for static files - extensively.

Try locating any other modules you're not using and turning them off.
For most of the performance tests I've done on systems running
mod-python/mod-perl, it really makes a difference - sometimes
immediately noticeable.

I've keep alive off, for many cases in serving dynamic content
KeepAlive in Apache will not help you at all. When it comes to serving
static content, and especially lots of javascript/css/image files for
web-pages, then it's a blessing - you can keep it on on your static
file server, whether it's Apache or something smaller/faster.

Re: Changing the database - attribute errors

[Merric Mercer]

Another observation after more investigation.

I decided to do the following:-

1. Drop the table (again) from the DB.
2. Alter the Model in Django.  This time I deleted one of the original 
fields named "rrp".

Then:-

1.  I re-ran syncdb.  This confirmed  the creating of a new table in the db
2.  I checked  the db and the admin - again both of these showed up 
correctly with all the fields  from my Model.
3.  In the shell I then tried to run a query set on the table.   I got 
the following error

" OperationError: (1054, "unknown column 'promotions_product.rrp' in 
field list)"

This was the field that I deleted from the model.

This is making me conclude that django is using two versions of the 
information in my Models.  The updated version is being used to 
correctly update the database and the admin - but the older version is 
being used to run the query sets.

Re: Changing the database - attribute errors

[MerMer]

This is a follow on from my previous email.  Things have got even
stranger and unpredicable.

I dropped the table from the database and then ran syncdb to re-create
a completely new and empty db.  However I STILL
cannot get the new fields to be recognized.  All the previous fields
are available.

The shell confirmed that a new table had been created.   I checked in
the DB and in the Admin and both or these
were working as expected.  I added a new record on all the fields via
the admin.

In the shell I run the following to return the new record and return
all the attributes.

record = Product.objects.get(id=1).
dir(record)

This shows that I cannot access the extra fields that I added to the
model.

This is really shaking my confidence in the system and I'm not sure
what else I can try.

Changing the database - attribute errors

[Merric Mercer]

When I want to add a new field to a database, with existing data, I 
normally don't have a problem as long as I follow these steps.

1.  Alter the django model.
2.  Manually adjust the database table ( mySQL)
3.  Run syncdb

However,  I used these steps this morning and it has not worked. The new 
fields are working fine in the Admin but I cannot access them 
elsewhere.  When I try to access them via the shell they are not 
recognized as attributes.   I've checked and double checked the 
settings, but nothing seems to help. 

What makes this even stranger is my colleague, working on a replica 
model, has created the extra fields without any problem. 

This has got me completely stumped.  Any ideas appreciated!

Re: How much is Django memory footprint?

[Nuno Mariz]

The processing is nothing in special, right now a weblog and a online
store.
I've removed some modules, like fcgi, include and suexec(I can't
remember the instalation of this modules ;) ) and the size of the
processes is now 22Mb.
Do you have KeepAlive On?
In my case did't solve the problem.
Also, can I reduce the memory footprint if I had a independent server
to serve static media, like lighttpd?
Lets see if the processes will maintain in 22Mb size.

Re: Subversion: How do you set up multiple branches of the same project on the same machine?

[Aidas Bendoraitis]

After some googling I found the solution myself.

For each branch of the same project I can set the following directives
in my Apache configuration:

SetHandler mod_python
PythonHandler django.core.handlers.modpython
PythonPath "sys.path+[r'/absolute/path/to/the/trunk']"
SetEnv DJANGO_SETTINGS_MODULE someproject.settings
PythonDebug On
PythonAutoReload On
PythonInterpreter someproject


SetHandler mod_python
PythonHandler django.core.handlers.modpython
PythonPath "sys.path+[r'/absolute/path/to/the/somebranch']"
SetEnv DJANGO_SETTINGS_MODULE someproject.settings
PythonDebug On
PythonAutoReload On
PythonInterpreter someproject2


I also symlink media directories respectively to someproject-media and
someproject2-media  in Apache htdocs.

Anyway, thanks, Scott, for your help as well.

Regards,
Aidas Bendoraitis [aka Archatas]

I think probably its much easier and very fast to completely customize
your form via HTML template.
I also belive that using django templates to render HTML is much
better suited tool vs. trying
to dynamically construct HTML inside of Python script. Here is example
of what I mean:

Re: newforms and output of required fields

OK I also started worrying about it today because one of my customers
asked me to
add asterisks to the required fields. I told I have a trouble with it
(hacking
around _html_output will not help since its already too big function
which seems needs
a refactoring.

Instead I have made decision to move all my forms to direct rendering
via
template. Results were astonishing since it uses less code  and seems
to be much
flexible then core technique. So since today I am moving all my forms
to use TemplatedForm.

I have explained the technique with example code here:
http://code.djangoproject.com/wiki/TemplatedForm

Please feel free to use it.

Regards,
 Alex

Re: How much is Django memory footprint?

[Atilla]

I've a moderatelly small apllication in production, that runs on FCGI,
instead of mod-python. From stress-tests it's prooven to be very fast
and responsive. FCGI is dynamically managed by Apache.

The memory footprint of my FCGI processes is around 12MB per process,
In addition, my Apache processes take around 6MB each.

I guess that ~18MB per process is normal in your case. A 50 MB process
is quite large however, what type of processing are you doing?

Also - for most of the cases you'd like to recycle an apache child
after a number of requests, so set the MaxRequestsPerChild to some
reasonable limit. If it is unlimited and something in your code
doesn't collect garbage memory properly, or it leaks memory, you'll
end up with your Apache children growing significantly, and loosing
the  copy-on-write pages that are shared between children.

In addition, make sure you take off any Apache modules that you're not using.

You really can't do it using standard ManyToManyField. The common way is 
to create this relation explicitly:

 class Record(models.Model): # or whatever name fits
   course = models.ForeignKey(Course)
   trainee = models.ForeignKey(Trainee)
   company = models.ForeignKey(Company)
