you did not install MySQLdb which is the python module used to connect to

Help with manage.py syncdb

[jd_python]

Hello there,

I am a newbie learning Python/Django...

Am using the following tutorial located at:

http://bit.ly/eIdT

Created a mysite database in MySQL 5 running on Snow Leopard.

Edited the settings.py file to look like this:

DATABASE_ENGINE = 'mysql'   # 'postgresql_psycopg2',
'postgresql', 'mysql', 'sqlite3' or 'oracle'.
DATABASE_NAME = 'mysite' # Or path to database file if
using sqlite3.
DATABASE_USER = 'root' # Not used with sqlite3.
DATABASE_PASSWORD = '' # Not used with sqlite3.
DATABASE_HOST = '' # Set to empty string for localhost.
Not used with sqlite3.
DATABASE_PORT = '' # Set to empty string for default. Not
used with sqlite3.

Now when I run the following command:

python manage.py syncdb

I receive the following error:

Loop through your vehicles as your simple naive start, eg:

data = []
for vehicle in vehicles:
 data.append([vehicle.ve_name, vehicle.ve_type])

Then expand. Looping through your query set and your models is pretty 
much the same be it reportlab or not.

Django and reportlab table question

[adelaide_mike]

I am attempting to user ReportLab with Django to make a report
displaying my data in a tabular format.

An example model is:

class Vehicle(models.Model):
ve_name = models.CharField(max_length=20)
ve_type = models.CharField(max_length=20)

My report generating view a copy of the example in the ReportLab
docs.  I have marked my sticking point with '''

def testX(request):
# Our container for 'Flowable' objects
elements = []
# A large collection of style sheets pre-made for us
styles = getSampleStyleSheet()

# A basic document for us to write to 'rl_hello_table.pdf'
doc = SimpleDocTemplate('rl_hello_table.pdf')

elements.append(Paragraph("Vehicle Summary", styles['Title']))

vehicles = Vehicle.objects.all()

'''the question is how to modify the following lines to read the data
from vehicles rather than use the hard coded data shown in the
example'''

 data = [['Caves', 'Wumpus Population'],
['Deep Ditch',50],
['Death Gully',   5000],
['Dire Straits',  600],
['Deadly Pit',5],
['Conclusion','Run!']]

'''after that, I think I can sort out the following'''
# First the top row, with all the text centered and in Times-Bold,
# and one line above, one line below.
ts = [('ALIGN', (1,1), (-1,-1), 'CENTER'),
('LINEABOVE', (0,0), (-1,0), 1, colors.purple),
('LINEBELOW', (0,0), (-1,0), 1, colors.purple),
('FONT', (0,0), (-1,0), 'Times-Bold'),

# The bottom row has one line above, and three lines below of
# various colors and spacing.
('LINEABOVE', (0,-1), (-1,-1), 1, colors.purple),
('LINEBELOW', (0,-1), (-1,-1), 0.5, colors.purple, 1, None,
None, 4,1),
('LINEBELOW', (0,-1), (-1,-1), 1, colors.red),
('FONT', (0,-1), (-1,-1), 'Times-Bold')]

# Create the table with the necessary style, and add it to the
# elements list.
table = Table(data, style=ts)
elements.append(table)

Can anyone give me a push in the right direction?  Thanks for any
help.

Is 'sub.domain.net' really what you use in your configuration or have
you changed the name to protect what you are using?

In this case it is critical that the unmodified original configuration
is seen because you changing names to protect stuff could have
destroyed parts of the original configuration that show the problem.

Anyway, the basis of the error message is that for whatever value you
have set WSGIProcessGroup, there is no corresponding WSGIDaemonProcess
directive of the same name to match against.

BTW, state what version of mod_wsgi you are using and make sure you
aren't using mod_wsgi older than 2.4 in case you are getting hit by
rare configuration corruption bug.

Thanks for your help!

Indeed a {% url %} tag was calling a view directly with the
unfortunate name 'settings', which I had renamed. (named url patterns

Wrong conclusion. Attackers cannot shoot holes, they can only expose them.
There are definitely design decisions you can make to prevent holes, one of
the obvious ones is to validate user input.
There are two assumptions made in this discussion that are not absolute
truths:
1) If an application receives more attention from critical eyes, it is more
   secure as it lessens the chance that mistakes have been left in
releases.
   However, this doesn't exclude the possibility that there are no mistakes
   to be found to begin with or even that these eyes find them or that they
   are practical security risks. MD5 is a good example. It has been secure
   for many years, because the computational power wasn't there to make
   any practical attack vectors.
2) If something is used more, it becomes more of a target. This still
doesn't
   exclude the possibility that an attacker will never find your machine.

Correct, signals won't help spot changes in the database that do not 
pass through Django.

I've done something similar to this in the past so I can integrate Plone 
(which pushes straight to the db) with Django. I have a database trigger 
that writes to an audit log table. That table has a matching Django 
model. So then I have a cron job that runs every couple of minutes, 
looking for any changes on the table and then does some work (in this 
case updating navigation and search).

This lets me stay in the Django ORM as much as possible, with the 
addition of just one trigger.

This is Django processing a {% url %} tag in the template.  {% url %} does
reverse mapping and requires that the entire URLconf be valid.

Ultimately when trying to initially populate the reverse dictionary for
reverse url resolution, the code ran into a situation where instead of an
expected callable or string that could be resolved into a callable, a
Settings object was found.

So, there's something wrong in the overall URLconf.  Possibly the local
variables you could access from the stack trace on a debug page would point
you toward which one.

DB table hook/callback

[Ishwor Gurung]

Hi folks,
Is there any way in Django to have a global hook (not Python hook, an
architecture hook rather :-) on a database table?

I want to get notifications in my django layer of changes in DB i.e.
whenever theres an update/delete. Is this feasible or am I heading the
wrong way?

The doc[1] says -
"Django includes a “signal dispatcher” which helps allow decoupled
applications get notified when actions occur elsewhere in the
framework." The word "framework" is I think the key here. Right?

pre-save,post-save amongst others..in Django is I think no good here
because the data does not get changed via save( )/create( )/... within
the our code (database tables get updated through other means)

A way which I think this can work is having field within the db that
gets polled every say 5 minutes OR using database triggers as a
callback (this one is the one I want to implement but is it even
possible?)
Maybe I am trying visualizing a bit beyond what Django is capable of
hmm.. Any thoughts / suggestions / recommendation? Thanks a lot.

Agreed all the way across.

One of the reasons I use django is because it's hard to shoot yourself in the 
foot and by making sure the lower level apis is where most of the important 
security features we all want live, and makes customizing our own special ones 
easy.  Python, well it's the love of the language, postgresql cause of the 
features it has, has had them a lot longer than mysql and a nicer memory 
footprint. 

And the latter part of your statement is exactly why we all think that open 
source software is more secure than propietary software and swear by it.

 From a couple of paragraphs above that note, in the description of order_by
here:

http://docs.djangoproject.com/en/dev/ref/models/querysets/#order-by-fields

To order by a field in a different model, use the same syntax as when you
are querying across model relations. That is, the name of the field,
followed by a double underscore (__), followed by the name of the field in
the new model, and so on for as many models as you want to join. For
example:

Entry.objects.order_by('blog__name', 'headline')

mixing annotations and extra()

[HARRY POTTRER]

If you had a model called Flight which has two fields, one called
"total_time", and the other called "distance", you could create a
"speed" field like so:

Flight.objects.extra(select={'speed': 'distance / time'})

Each object will now have a 'speed' field. What if one of those fields
is a result of an annotation? In my particular case, 'distance' is
stored as an attribute of a Route object which is attached to Flight
via Foreign Key.

Flight.objects.annotate(distance=Sum('route__distance')).extra(select=
{'speed': 'distance / time'})

which doesn't work. How can this be achieved? Or is it even possible?

mod_wsgi error which i have no idea how to fix

[Damon Jablons]

Hey,

I'm running Nginx which proxies Apache and on my website, I get the
following error when I tail the Apache log:

[Mon Nov 16 23:51:08 2009] [error] [client 127.0.0.1] No WSGI daemon
process called 'sub.domain.net' has been configured: /var/www/django/

Here's my Apache config for this site:

#Basic setup
ServerAdmin w...@domain.net
ServerName www.sub.domain.net
ServerAlias sub.domain.net


Order deny,allow

Thinking permissions were the problem, I ran: # chown -Rf www-data:www-
data /var/www/django/
and then: # chmod -Rf 755 /var/www/django/
after restarting Apache, I receive the same error.

Here's my wsgi file:

site.addsitedir('/var/www/django/domani/env/lib/python2.6/site-

def application(environ, start_response):
environ['wsgi.url_scheme'] = environ.get('HTTP_X_URL_SCHEME',

   return _application(environ, start_response)

Any ideas?

Thanks in advance.

Open source helps this a lot, lets not forget this.  

PHP application problems that we see are bad coding techniques, mostly in 
older software that's been coded since php4 and updated for later versions of 
php, which says to me that they didn't take into account half of the known 
vulns today because they weren't known yesterday.

We also have to take into account all the ways a user might try to use our 
software, because they are lazy and not always vigilent, which is the main 
area that bad guys prey on.  For example, redirecting after a login to break 
the back button so the next user can't get the login form details. It's hard 
to speculate everything a person will do, too many individuals with different 
view points.  Even using large test groups it's hard be 100% correct 100% of 
the time.


In the end all you can do is prevent what is known today, hope that you've 
covered for tomorrow.

Red Hat Unveils New Ad Campaign 

Linux distributor Red Hat has announced plans for a $650,000 ad campaign. The
ads will appear on several major newspapers as well as on a few selected
websites. "These ads will be targetted towards Windows users who are fed up 
but
aren't aware of any OS alternatives," a Red Hat spokesman said. "We feel that
there is a large audience for this." 

One of the ads will be a half page spread showing two computers side-by-side: 
a
Wintel and a Linux box. The title asks "Is your operating system ready for the
year 2000?" Both computers have a calendar/clock display showing. The Windows
box shows "12:00:01AM -- January 1, 1900" while the Linux box shows 
"12:00:01AM
-- January 1, 2000". The tagline at the bottom says "Linux -- a century ahead
of the competition."

so if we follow your logic to the inevitable conclusion, the moment the bad

congregate elsewhere. After all bitbucket is big enough to be on their radar - 
and it got hosed - although I hear that was an amazon problem, not a django 
issue (could be wrong).

Yep, you can also try writing the tracebacks in your code while using
development server
(http://docs.python.org/library/traceback.html)

import traceback
class Foo():
try:

except:
print traceback.format_exc( );

Some of my models had GeoDjango models in them.  For these, I need to have

Re: Default sort order in admin

[Zeynel]

Yes, this is probably true. I am still learning. And I like Django and
how it works but it takes time to understand some concepts. I was
rushing a little bit because I wanted to meet this challenge

mentioned here:

But it took me 2 weeks to finish this very simple app.

And I'm still trying to resolve this last issue. If you look at the
pictures here  http://zeynel.posterous.com/django-template-problem
 the title "Search lawyer by last name" should not be in the /admin/
wkw1 directory because the search box is in /admin/wkw1/lawyer/.

How do I change that title?

Confusing error: AttributeError: 'Settings' object has no attribute 'rindex'.

[Gene]

I'm getting an error that has completely perplexed me: AttributeError:
'Settings' object has no attribute 'rindex'.

The complete traceback is listed below. I get this for any request but
a root request '/'. I'm, using Django 1.1 with mod_wsgi.

Something along these lines should work in SQL:

SELECT s.stock_symbol
  , AVG(sp.price) AS average_price
FROM Stock s
  LEFT JOIN StockPrice sp
 ON s.id = sp.stock_id
WHERE sp.date BETWEEN DATE_SUB(CURRENT_DATE, INTERVAL 6 MONTH)
   AND CURRENT_DATE
GROUP BY s.stock_symbol

You weren't reading closely enough. The page Karen linked you to is
all about admin options, and that option therefore belongs on the
ModelAdmin class, not the model itself. The other page explains how
you set the default ordering for a model throughout the application,
which the admin will also use if it doesn't have anything else set.

order_by related models

[dave.l]

Hi!

The following line in my application seems to have stopped working as
I expect:

   for object in self.queryset.select_related().order_by
("app_building.principal_name", "reference"):

the first ordering term on principal_name is no longer working.  by
looking at ...query.as_sql() I can see the ORDER BY is not being
added.

According to the docs:

   New in Django 1.0: Please, see the release notes

   The syntax for ordering across related models has changed. See the
Django 0.96 documentation for the old behaviour.

but I cannot find any reference to the new syntax

I have looked at the source, and it appear that if I could use "
app_building.`principal_name` " (i.e. with 'backticks') it would work.
but these are rejected by the regexp match.

Please could someone point me in the right directions.

Thanks,

feature request

[Brandon]

How do I request a feature from Django?

This one would be simple. I'd like the authenticate method to take an
extra boolean argument which would determine if it should treat the
username as case sensitive. Default would be True, since it treats it
that way already.

I understand that passwords would have to be case sensitive, because
they are hashed, but usernames should not have to be case sensitive.

It is not appealing to me to convert all the usernames in my db to
lowercase and then lowercase the input to authenticate().

Is there a way to do this already? My way seems like it would be
easier to add the check into authenticate() instead of the following
workaround.

query the db with User.objects.get(username__iexact=unamefrominput)
#obviously using a try/except

if there is one, take the username of that user and pass it to
authenticate() with the password from input.

this workaround obviously requires one more query than putting the
decision in the authenticate function.

Any help on this would be greatly appreciated. I am developing for a
server run by someone else, so I don't want to hack django myself as
it won't affect the production server. This would be really handy for
future issues.

Did you check your apache logs? Normally when I get these, the error log will 
produce good info, if it doesn't do that atleast, I start over and check 
everything step by step. If the template suggestion doesn't work.

And to Christophe Pettus:  yes it's mainly for ruby on rails, but it does 
python also as of 2.01-rc1, according to the dreamhost wiki and the phusion 
passenger site.

You can use mod_passenger for python, with a passenger_wsgi.py file.

(I use it on my development machine with Passenger.prefpane so I don't
need to fuddle with vhosts).

If you notice - you are looking at two ways of doing it, depending
whether you want the ordering to be applied to just the model
(django.models.Model) or the ModelAdmin
(django.contrib.admin.ModelAdmin).

regular models use Meta class for ordering - ModelAdmin classes use an
ordering attribute.

The modeladmin docs say : "If this isn't provided, the Django admin
will use the model's default ordering."

so they are both "correct"

Serving Password Protected Files

[f4nt]

Hello,

Is there a good way to handle serving files behind django
authentication? I'm working on a project right now where people can
upload files, and based on certain permissions can download them as
well. However, there doesn't seem to be a good way to handle checking
authentication, and then serving the files. I'd prefer a web server
agnostic approach since I'd like this application to stay as pluggable
as possible. Any thoughts?

Thanks,
Mark

Re: Can I change the title of an admin page?

[Zeynel]

In case someone else has the same problem: I hard-coded the text I
wanted in between h1 tags in template base.html.

{% block content_title %}{% if title %}Enter last name{%
endif %}{% endblock %}

but this defeats the purpose of templates. If you know how titles are
created in django, please let me know.

Can I change the title of an admin page?

[Zeynel]

I found that the base.html template takes the title in admin change
page from the title of the page:

line 64 in base.html:

{% block content_title %}{% if title %}{{ title }}{% endif %}
{% endblock %}

How can I change the title of the page? Does anyone know?

There are three lines of code listed (not a complete test or anything that
someone could run locally and see what happens) and the statement that they
are "not working" with no explanation of what, exactly, that means.  Do you
get an error?  Does the test fail when you think it should pass, or pass
when you think it should fail?  Does your computer burst into flames?

There is reference to a "confusing mishmash" of Google results without
specific citing of any one that might could have provided a few pointers as
to the nature of the problem inherent in those three lines of code.   I,
personally, prefer puzzles with a few more clues, so I recall reading that
message and moving on without really looking too closely.

Looking again, I'll make a guess.  Is the problem you are attempting to ask
about that the session variable set on the test client side is not reflected
in the session as seen by the server view?  If so, then likely you are
looking for ticket #10899 to be fixed:

http://code.djangoproject.com/ticket/10899

That includes what looks to be straightforward (if self-described "ugly")
ways to work around the current behavior in the meantime, though I have not
experimented with any of that code.

If that is not the problem you are hitting then you would likely get better
results if you would spell out in some detail what the problem is.

I think the problem here is that if string2 is not required it will be
in the cleaned dictionary but an empty string. So instead you might
need:

if not cleaned.get('string2', ''):
cleaned['string2'] = string1

I'd still suggest doing it like this though, not in the POST, as you
would need to do that in every view where you use the form.

generator function for repetitive model fields?

[Some Guy]

Hi,
Is there any functionality, or possibility, to generate many fields in
a model file that are all identical and follow an easy (repetitive)
naming convention?

i.e.

locations = (loc1, loc2, lo3)
places = (place2, place2)
for l in locations:
   for p in places:
  l + p + _has_been_checked = models.BooleanField(...)

right now I"m just running this kind of thing in a shell and copy/
pasting.  Any ideas how this could work? Manager methods maybe?

TIA

Thanks for responding.  I'll have to look into using POST.  The problem
with NOT requiring string2 is that I still can't change the value.
Instead of checking if it's not there, I check for an empty string:

if cleaned["string2"] == "":
cleaned["string2"] = string1

which means an empty string goes along with POST, not the value I set.

How write unit test for forms that download PDF file

[JohnL]

On my website http://www.mathmaster.org, I have a lot of forms that
generated a PDF math worksheets file after the user click the submit
button.

The way I test these pages is using the code similar to this method:

def test_addition_post(self):
  post_data = {
'max_value': 10,
'min_value': 1,
...,
}
response = self.client.post('/addition/', post_data)
self.failUnlessEqual(response.status_code, 200)
self.failUnless('Data received', response.content)

I don't think the code is working correctly because all my tests
passed and I still get a simple reference error.

StockMarket

Stock

StockPrice

If StockPrice has price and date fields, and one price entry for every
day for every stock how would I write a query to get the average price
for a given stockmarket for the last six months?

A long and complex report written by someone who has good communications 
skills and who knows English fluently is likely to have fewer spelling 
mistakes and grammatical errors than someone who uses Google Translate 
to translate even a short and simple report to English from some other 
language.

OK so if you remove basic from both the import and the directory path, then
you are left with an include, in that file above, that is:

from inlines.parser import inlines

?

Now the problem is you have two "inlines" modules
(/django_apps/live/inlines/ and
/django_apps/live/inlines/templatetags/inlines.py) and "from
inlines.whatever" is ending up looking in the wrong place (the inlines.py
file instead of the directory two levels up).  (This is likely why the basic
was included in the import in the first place.)

I'd recommend returning the apps to their originally-coded state and using
the structure they are assuming.  Otherwise I do not know how much
additional renaming you will need to do to to make things work properly.
For this problem here you will need to rename one of the inlines modules
(and update all imports that reference whichever one you decide to rename).

Re: django basic blog and inlines

[Bill Freeman]

So then the answer to my question is "no", you do not have a file
inlines.py in a directory named "templatetags" which is itself in an
app directrory recognizable by the presence of a models.py, the path
such that the models.py file is importable as appname.models, and the
app mentioned in INSTALLED_APPS.  Since those are the only places the
loader will look for the "inlines" tag library, it won't find one.

Re: django basic blog and inlines

[Bobby Roberts]

Karen -

Thanks for your reply... The path in both my blog and inlines module
was edited and i removed basic. from all the calls (since i wasn't
using the primary basic/ directory with all of the standard apps.  The
error was there even if when i was using basic/blog or basic/inlines
structure as downloaded from the source.

Mike -

Thanks for your reply.  The path to the inlines.py file is as follows:

/django_apps/live/inlines/templatetags/inlines.py

Re: Encoding ISO-8859-1

[Hugo González Monteverde]

What editor are you using  for the template? There's no point in
specifying the encoding as a meta if the actual html template files
has not been saved in that encoding. Use the same encoding in your
editor settings as you are using in your meta specification.

Either  your template file has a BOM or Django is interpreting that it
should be UTF8. The easiest way to fix this is saving the file as UTF8
and changing your meta settings. All characters in Latin 1 are in
Unicode so you can stick to unicode for all of it.

The inlines.py needs to live in your project/app/templatetags directory.

I''m assuming live is your project,inlines is your apps, so something like 
this:

django_apps/live/inlines/templatetags/inline.py 

you should read this:
http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#code-layout

No, that's a red-herring error message.  Django actually tries to load tag
libraries from a templatetags directory under each app listed in
INSTALLED_APPS.  The fact that only django.templatetags is shown in the
error message does not mean that inlines.templatetags wasn't tried.

I think the problem is likely that you have removed the 'basic' element from
the directory path for these apps.  The blog one may not care, but it
appears (I'm assuming you are using the basic apps from here:
http://github.com/nathanborror/django-basic-apps) that the inlines one, as
coded, requires that basic be part of the app path.  See for example:

http://github.com/nathanborror/django-basic-apps/blob/master/basic/inlines/templatetags/inlines.py#L2

Those imports include 'basic' in their path.  If you have removed 'basic'
from the path where they are actually installed those imports are not going
to work any more.

Re: django basic blog and inlines

[Bobby Roberts]

the path to inlines.py is:

/django_apps/live/inlines/inlines.py


live is on my pythonpath (my main application)

blogs and inlines were pulled out of the basic app and put into these
directories

/django_apps/live/blog/  (works)
/django_apps/inlines/(doesn't work)

you can view the full traceback here:  
http://www.thecigarcastle.com/blog/2009/nov/15/asdfasd/

it's like it's trying to call inlines from
django.templatetags.inlines   rather than from the inlines path noted
above.

How is it not logical?  Product A is widely used, Product B is used less. Bad 
Guy A. is smart enough to realize that product A if broken can be used to gain 
him more presents because more users have it. This is because of the human 
condition of laziness and the majority are not really paying attention to what 
they are doing. This is a fact. If you're one that thinks about everything 
they are doing, i.e. every litteral step yout take down the hall is carefully 
planned.  Then you are most likely going to avoid Bad Guy A, and be a 
minority.  I hardly meet people who do this, they just act without thinking. 

Its illogical to think that everyone or the majority will not succumb to 
laziness because this is our ideal goal as a society.  Everything we build do 
is to make our lives easier so we can be lazy without worry.

clean() is run after the built-in validation and per-field validation.
You'll want to copy request.POST, set the value there, and then feed
it to the form. Or make string2 not required and do it in clean the
way you do now.

Changing the admin templates

[Zeynel]

My app is almost done but before I send it out to get some feedback I
want to make a couple of more design tweaks.

I changed the branding on the login dialogue box and on the dark blue
band on top, by changing the template base_site.html.

On the home page (www.swimswith.com/admin/) I want to change the title
"Site administration" and on the change page (www.swimswith.com/admin/
wkw1/lawyer) I want to change the title "Select lawyer to change".

I went through each template in the directory

/webapps/django/lib/python2.5/django/contrib/admin/templates/admin

but could not see any similar text to change. Can anyone help about
finding the right template?

Thanks.

Using Sass with Django makes CSS so much easier to maintain

[Jason]

I had been eyeing Sass for a while, hoping to get to use it on a
project. When we chose Django instead of Rails for FeedMagnet, I was
bummed that we wouldn't have access to the Rails Sass gem.

Thankfully I found Compass - it let's us generate all our CSS from
Sass source files and it works really well. Even thought it is built
in Ruby, we don't need to run it on our production server - just on
our development boxes. It updates our CSS automatically every time we
change a Sass file - all we need on the production server is the
generated CSS. Even though it is not an "integrated" solution, as far
as I can tell Compass is the best way to get Sass working with Django
- and it has definitely been worth it to get to use Sass - huge time
saver.

I wrote a blog post to show how we're using Sass to set up our grid
variables that set the width of pretty much every block element in the
site. I thought I'd share how we were doing things in hopes that
others can benefit.

Here's the link to the post: http://budurl.com/sass

Django i18n

[Carlos Ricardo Santos]

Hi:

I tried all the ways possible and impossible to make my Django project have
i18n...
Put all settings (INSTALLED_APPS, CONTEXT_PROCESSORS), generated languages,
compiled messages, edited the ".po" files, setted the ugettext to "_", in
views all the strings are like this: toSend= _("Hello"), but so far... only
the Administrator panel is translated cause I checked (put a post form to
change the language in the backoffice).

I found that changing language only works for POST requests... Ok, DONE.
But even with a post... only the backoffice seems to be responding to my
language change request...

I use to folders at app/locale:

pt-PT
en-GB

Any ideas? Someone has implemented a foreign language before?

Thanks in advance.

Trouble setting a form field's value in clean()

[Adam Stein]

Running Django v1.1.1 on Apache v2.2.8 with Firefox v3.5.4.

I have a very simplified and unreal example below to demonstrate what's
happening.

class MyForm(forms.Form):
string1 = forms.CharField()

string2 = forms.CharField(widget = forms.HiddenInput())

def clean(self):
cleaned = self.cleaned_data

if not cleaned.has_key("string2") and
cleaned.has_key("string1"):
cleaned["string2"] = string1

return cleaned

As seen, both 'string1' and 'string2' are required.  In the clean()
method, if string2 isn't defined, I set it to a value.  For my simple
case, I'm just setting it to the value of another field on the form.

What happens is that Django comes back with an error message because
'string2' is required and has no associated value.  Is there any way to
set a field value that get's POST'd?  Even if I make 'string2' not
required (so it winds up being an empty string), there still doesn't
seem to be a way to change the empty string to have a value.  While
validation passes, the resulting POST data still shows 'string2' as an
empty string.

I thought that changing and returning the cleaned data would do it, but
apparently not.

Metaphors are messy and tend to break down. There may be more spelling
mistakes in the Drupal letter, but that is because it is a letter and django
is an alphabet...

Re: django basic blog and inlines

[Bill Freeman]

Do you have among your installed apps a name identifying a directory on the
python path having both a models.py and a subdirectory named templatetags,
that subdirectory containing a file inlines.py ?  Or was that in the stuff you
excluded from basic.app?

It is quite simple. Say you write a letter. You proofread the result.
You give it to someone else to proofread and it's likely he/she finds
a few more typos. The longer the letter, the more mistakes you'll
make (absolute), while the percentage might stay the same.
The more eyes look at it, the better your chances are that you will
send a flawless letter.
Now, the question arises whether a program is more secure if it has
more exposure (proofreaders) or less and a bit of both is true.
The more proofreaders the less chance a bug remains, yet since
exploiting the bug requires knowledge to be shared and/or
incorporated into attack software, the chance that *you* as a user
gets exploited through one of these bugs lessens.
Think of this as the difference between a cabin in the mountains,
no locks on the door and a 5 mile steep hike to get there, versus
a bank downtown. Obviously, the bank is more secure, yet it's
much less likely that someone will try and rob the cabin.

The meta tag, I'd guess, will affect how the browser interprets the data.

FILE_CHARSET is a setting, so you need to put it in your settings.py file,
not in any template file. Include:

FILE_CHARSET = 'iso-8859-1'

in your settings.py file (and, if necessary, restart your server).  Then
Django will stop assuming that your template files are encoded in utf-8 and
instead will read them assuming iso-8859-1 encoding.

Note if you also want to retrain this encoding, instead of utf-8, for all
responses sent by your application, you will need to also set
DEFAULT_CHARSET:

http://docs.djangoproject.com/en/dev/ref/settings/#default-charset

By default Django will encode outgoing responses in utf-8, so if you want to
send your responses with another encoding you need to change this one also.
But I am not sure why you would want to do that instead of just sending the
response using utf-8?

With php+smarty I do the same I make a base template on which I have

Re: What would cause an app to not register?

[Mark (Nosrednakram)]

Hello,

I'm not expert but have seen this behavior when I have a bad import.
I would start by trying  ./manage.py shell and copy past your imports
from models and then views or other imports.  It's almost always been
a bad import when I've seen this and ./manage.py syncd will fail
silently and ./manage.py validate won't find any errors.  Hope this
helps let us know what you find please.

Just add it to the ModelForm. Extra fields added to modelforms work
the same as normal forms.

Just add it to the CustomerForm class. A ModelForm is pretty much a normal
Form with some logic to auto generate the fields from the Model.

Thank you all for your replies.  Karen, both good points.  pjrharley,
I agree with Dennis.  If the user is required to re-type their email
address, then that in combination with Django's simple built in email
validation should be sufficient.

I am using a ModelForms right now.  If I remove email_conf from my
model, do I add it to the ModelForm, place it in the html form or
create a new form to handle it?  I guess I'm still a little unsure as
to when to use Forms over ModelForms.

That totally worked!  Thank you.  Could someone please explain to me though 
what exactly that snippet is doing?  I'm still quite new to Django, and I'm 
not yet used to this "drop this file in here and watch the magic go" way of 
doing things.

sure, if this is REALLY a requirement, then build it into your model's
save method

when you save the review, set the submission status directly from the
save method, not via signals

Encoding ISO-8859-1

[ulferik]

My problem is that when I put one of these characters (´ Å Ä Ö) in the
template I get an error like this "UnicodeDecodeError: 'utf8' codec
can't decode bytes in position 578-579: invalid data"
Normally I specify the encoding in meta like this "charset=ISO-8859-1"
or "xml version="1.0" encoding="ISO-8859-1" ". There must be a way of
changing the encoding in Django. If anyone know how to do that please
post it here:

It works exactly the same, as the document I linked to shows. The
syntax you give should work with a standard ForeignKey - did you try
it?
