breadcrumb solution

[Mike Dewhirst]

I would like to get breadcrumbs working in a simple way. Could anyone 
please help?

I think I need a singleton with a dict like this ...

bread = singleton()

bread.dct['last_title'] =

Within each view and before doing anything else I want to ...

def someview(request):
title = 'whatever'
crumb = bread.dct['last_title']
bread.dct['last_title'] = title
# put title and crumb into the view context for extraction
# in the template as {{title}} and {{crumb}}


Is there a better way?

Thanks

Mike

How to display and update selected fields from a model

[Jim Myers]

I have a database model with many fields, some of which I don't want
displayed in a form and others I don't want to be editable.  Is it
possible to do this with a ModelForm?  Or is it even possible with
regular forms?

Furthermore, I only want the SQL update statement to update ONLY the
fields actually displayed in the form (only the editable ones).  I
know it can do it if I write my own SQL but does Django provide a way?

I've read most of the available docs and a lot of stuff on Google and
still don't see how to do these things.

Any help/insight will be appreciated!

How do you plan to tell if the guest "came back"?  The only reasonable
mechanism I can think of is to use a session cookie (you can't rely on
things like IP address ... like most folks with a home router, all the
computers in my household will appear to have the same IP address to a
service we contact, and the same would be true for most business
situations).  And even if you rely on a session cookie, your
restrictions are easily bypassed by the user who simply clears their
cookie cache.

Until you can solve this problem reliably (good luck!), the
implementation details are not really worth thinking about.  But
things like using a session cookie are no more or less secure for this
use case than they are for the usual approach to keep a user logged on
to a web app, other than the fact that you'd probably need to keep
your session alive a lot longer.

Craig

PS:  The typical solution I've seen for a "guest" concept is to offer
only a limited subset of the overall functionality to non-registered
users, with lots of teasers about "if you would only bother to
register, you could do FOO and BAR and BAZ!".  Example:  ESPN's web
site has a bunch of "freely available" stories accessible to anonymous
users, but the (presumbably) good stuff requires a login.  Figuring
out the balance point is a challenge -- for me, for example, I'm not a
fantasy football junkie, so the extra subscribers-only analysis
doesn't have enough value for me to bother to register (or pay, as the
case may be).

Actually, they can work standalone too.

There's GHRML (http://www.ghrml.org/) for HAML, but I don't think it's 
developed anymore. One issue is that choosing a different template 
language means giving up on django's tag libraries, which might or might 
not be a problem.

Is it secure "enough" to put login info in the session?

[ristretto.rb]

Hi

I want to have a guest concept.  You get instant access to my app.
There are limits.  But, you will be allowed to come back multiple
times before I require you to register.

When a user comes in as a guest, I will create a user with a bogus
username, password and email, and put  the user_id in the session, so
that when the user comes back I can read it and restore saved state.

I'm mildly concerned that it's unsafe to put the user_id in the
session.  I can imagine a hacker faking that somehow, and getting
access to other guest accounts.  I'm not sure the risk is that big,
and once users register, the risk goes down.  But, I'm wondering if
this is at all foolhardy.  Is there a better way to approach this?

Perhaps a hash key or something that isn't sequentially too
guessable.  Or some encryption.

This guest concept has inherent security issues with shared computers:
labs, cafes, etc.  The user will made aware of this when logging in as
Guest.  Also there will be no sensitive or private data in this guest
account that if seen by another user would make much difference.

Thanks for any insight
Gene

MySQL-Python and Snow Leopard

[Brandon Taylor]

Hi everyone,

After following the custom build instructions for MySQL from
Hivelogic, http://hivelogic.com/articles/compiling-mysql-on-snow-leopard/
MySQL is running just fine.

However, I can't get MySQL-Python 1.2.3c1 to compile. I have re-
installed Xcode for 10.6, but I get an error trace a mile long, ending
with error: Setup script exited with error: command 'gcc' failed with
exit status 1

Fun times. Has anyone been able to get this running? I'd appreciate
some pointers!

Thanks,
Brandon

Re: problem in define variables.

here is a simple view which defines and passes some variables to the template:

def downall(request):
""" view for display of downloads
"""
lst = Downloadtype.objects.all()

return render_to_response('web/downall.html',
{'lst':lst,
 'mn':makemenu('Downloads'),
 'rbox':rightbox(),'request':request,
 })
you will notice a dictionary of variables that can be used by the template. 
Here is the template:

{% extends "basefull.html" %}
{% block centercontent %}

Choose download category
{% if lst %}

{% for p in lst %}


{{ p.name }}



{% endfor %}

{% else %}
No download categories posted
{% endif %}

{% endblock %}

I would suggest you learn some python before going further.

File Storage Suggestions

[brad]

I currently have a django site running on a single machine (web server
+ database + file storage).  This site contains many multimedia files
(audio, video, documents) that are uploaded and retrieved by end-
users.

We've reached the point where we need to push the multimedia storage
off of this server, and I'm looking for suggestions on ways to do
this.  We're considering purchasing another machine or pushing our
files out to something like S3.

I've also run across django-storages, so I'm intrigued by the
solutions that it supports as well.

I'd just like to get feedback on what other people are doing before
jumping in too deep.

Thanks!

I believe FDS is simply Red Hat's LDAP server.  If you google 
"django ldap" there are a number of good resources on using LDAP 
for Django authentication.

Don't use wildcards, ie., '*', like that, it is unnecessary in this
sort of situation and technically will match other directories you may
not have intended to expose, if they so happened to exist.

I use TextPad with Python highlighting. It suits me because I'm used to 
it. I use the 'Run' option to launch Python with my unit tests or 
anything else for a quick syntax check. The results come back nicely.

Speaking of results I also like TextPad's search results (with or 
without re) and grep-like 'Find in files' which is very fast and lets 
you double-click a found line to open the file at that point.

I tried PyDev and like that too but found Eclipse too heavy when 
associated with SVN. I know there is SVN integration but I couldn't get 
it going smoothly enough so I gave up and happily went back to TextPad.

I'm definitely going to try Joshua's suggestion of pdb.

Thanks

Mike

Re: Abstract Base Classes

Actually, maybe it is working.  I should have been looking for _meta
rather than _meta_ .

But does anyone have an opinion about subclassing models.Model.__metaclass__ ?

Re: Having Trouble with Reverse method

[Peter Coles]

What you provided looks correct -- which means that something else is
probably broken...

Some things to investigate:

1. If you manually go that url: http:/in_development/
does anything get served?
2. Is your ROOT_URLCONF setup to properly point to this file in your
settings file?
3. Is this another url file than the one defined in your ROOT_URLCONF?
If so are you properly "including" this one from your root urls.py?
Details on include here: 
http://docs.djangoproject.com/en/dev/topics/http/urls/#including-other-urlconfs

You'll find a wealth of information about urls in django here:
http://docs.djangoproject.com/en/dev/topics/http/urls/

Once you get it working, you may find it more convenient to use named
url patterns: 
http://docs.djangoproject.com/en/dev/topics/http/urls/#naming-url-patterns

Re: Managers in admin

[Alasdair]

Thanks for your reply, Peter. When I set live = BadManager(), it
properly returns posts, so maybe the issue is with my
LiveEntryManager:

class LiveEntryManager(models.Manager):
def get_query_set(self):
return super(LiveEntryManager,self).get_query_set().filter
(status=self.model.LIVE_STATUS)

As for your other suggestions:
1. I haven't set list_display or list_filter for this model.
2. I don't seem to have imported another "models"

Live is my default manager because it filters down to published posts.
I like your method of adding a "published" method, thus keeping
objects intact. However, I was following a tutorial for writing custom
templatetags to fetch objects for any installed model:

http://www.b-list.org/weblog/2006/jun/07/django-tips-write-better-template-tags/

For the templatetag to filter down to published Entries, I need to
have 'live' as the default manager.

Re: Link for new page

Make yourself familiar with the django documention page—if you know

This sounds like you're trying to just put a link on a page? of the
format Click this link? The following will
show you the best way to generate the url for the "_url_here_" part:

http://docs.djangoproject.com/en/dev/ref/templates/builtins/#url
You should really give this a read too, naming url patterns can be
very convenient: 
http://docs.djangoproject.com/en/dev/topics/http/urls/#naming-url-patterns

Finally, you should really read the content provided under "First
Steps" on the doc page: http://docs.djangoproject.com/en/dev/#first-steps
Especially the intro overview 
http://docs.djangoproject.com/en/dev/intro/overview/#intro-overview
and then the tutorials

Abstract Base Classes

[Bill Freeman]

I'm trying to use an Abstract Base Class as described at:

http://docs.djangoproject.com/en/dev/topics/db/models/#abstract-base-classes

(Django 1.1, Python 2.6.2)

Things may be complicated by my desire to use a mixin:

class Mixin(object):
"""I will actually be creating some of these that aren't model instances"""
def _setFoo(self, v):
self._inner_foo = ...

def _getFoo(self):
...

foo = property(_getFoo, _setFoo)

# and other methods that process self that has _inner_foo

class AbsModel(models.Model, Mixin):
_inner_foo = models.FloatFiedl(...)

class Meta:
abstract = True

class Thing(AbsModel):
"""I want to use the property and methods from Mixin on these instances
and on instances of other subclasses of AbsModel without having to
define _inner_foo as a field in each lexical class definition (there are
actually a number of fields)."""
# Other fields
# Other methods

x = Thing()

So far, so good.  But, while x is an instance of models.Model, it is
not an instance of Mixin (according to isinstance, and also according
to the lack of a foo property).

I can make it seem to work by changing the Meta class declaration to:

class Meta(models.Model.__metaclass__):

The property is there, and isinstance reports that x is an instance of
both, but now Thing doesn't have a _meta_ attribute (so it doesn't
have fields).

Is this a bug in the Abstract Base Class mechanism, my efforts, or both?

Bill

Re: Managers in admin

[Peter Coles]

Are you certain that the django admin interface is actually using
LiveEntryManager?  I just tested this out (using trunk):

class BadManager(models.Manager):
def all(self): return self.get_query_set().filter(slug='')
def filter(self, *args, **kwargs): return super(BadManager,
self).filter(slug='')

and inside my model I have:

class Post(models.Model):
... (column declarations here) ...
live = BadManager()
objects = models.Manager()

When I try out my admin interface, it's properly returning Posts.
When I call Post._default_manager from a shell it returns an instance
of "BadManager"

If you're still seeing this problem with your code, maybe check for:

1. Are your "class Admin" values setup properly for this object?
list_display? list_filter?
2. Have you imported something called "models" into your models file
that isn't django.db.models, which is hijacking your "models.Manager"
declaration?

Some additional things to consider:
Any reason for having "live" as your default manager? Switching the
order of "live" and "objects" will make "objects" the default_manager.
Also, in practice I'll usually make a manager that adds some
additional features to the models.Manager and just use this manager as
my only manager. For example if I have Posts, where I tend to only
retrieve published ones, I might add a function called "published"
that filters down to published posts, which lets me do this:
"Post.objects.published()".  This way all the standard functions of
Post.objects are kept intact, but I have some additional features
available.

Re: django unicode user name

It's easier than that, since the username field is a CharField!

Add these lines to your admin.py:

# username to accept a wider range of character in the username.

help_text = _("Required. 30 characters or fewer. Alphanumeric
characters only (letters, digits and underscores)."),
error_message = _("This value must contain only letters,

You don't actually say what the problem is. What happens when you save
an object using the code above?

The main problem that i can see with your code is not with save()
particularly, but with the way you're accessing the related values.
'self.responsible' is a ForeignKey, so using it as the lookup value
compared to a 'name' field is not likely to work.

The much easier and more obvious way is to do this:

if not self.responsible:
self.supervisor = self.byline.supervisor
else:
self.supervisor = self.responsible.supervisor

You seem to have tried a random selection of things from different
blog posts, many of which reference old versions of Django. So for
example the 'class Admin' lines in your models is for a pre-1.0
version and no longer does anything. Similarly, if you're using the
HTMLField code from django-tinymce, you shouldn't need to reference
the javascript files directly in your admin classes - this is only
relevant if you're manually applying tinyMCE to your fields.

I suspect there are two problems: firstly, the value of TINYMCE_JS_URL
doesn't look much like a URL, it looks like a filesystem path. This
needs to be an actual URL which serves the Javascript.

Which brings me to the second problem: do you actually have anything
that serves static files such as Javascript? Remember, Django won't do
this for you, unless you ask it to and you're running on the
development server. Is something actually serving files from /media/?

Why do you need to turn it into a field at all? Why not just

return cursor.fetchone()[0]

which will return the first (only) field in the returned data, which
can be used directly in your template.

Also note that you can probably avoid all this by using version 1.1's
new aggregation features, since all you want is the total of
score.s_total for a relevant Player. As long as you have a ForeignKey
from the Score model to Player, you could just do this in your view:

from django.db.models import Sum
players = Player.objects.filter(p_uffl__icontains=q).annotate
(ptot=Sum('score__stotal'))

This generates the ptot values for every player in one go, which is
much more efficient as well as neater.

(And please, consider using better field names - unless this is a
legacy database, there's no reason to prefix them with the table
initial, and no reason not to give them properly descriptive names.)

Trying to get tinyMCE working on an admin page

[DrKen]

Hi, new to Django and tinyMCE. I'm trying to get the tinyMCE HTML
editor working on the admin page, so started out by doing the Django
tutorial, then attempting to modify. I've got the admin page working
with text fields instead of character fields, but don't see any change
whatsoever when I convert the fields to HTMLField() - my html content
appears as straight text, no syntax highlighting etc. I've googled all
over for suggestions and tried several dozen, but something is still
not happening. According to what I've been reading, this should bring
up an HTML editor on all of the (one) text fields. Suggestions
appreciated.

Re: custom methods

[Angel Cruz]

I think it is just my vision problems, but I can't find where you are
calling the method 'ptot' in your view.

to debug, I would add this in my view (after instantiating with your line:
player = Player.objects.filter(p_uffl__icontains=q):
.
my_total=player.ptot # -- if I was debugging in an IDE, I would put a
breakpoint here and step over and then check the value ##
.
.
return render_to_response('search_results.html',
   {'player': player, 'query':q, 'my_total':my_total})

and in your template, just for debug add:
 Here is my total: {{my_total}}

 I may be wrong, but I think you need to use 'url' method on urlpatterns
declaration:
 urlpatterns = patterns('dwrangler.project.views',

  Yes, this abc.js is a static file. You should setup your django do serve
static files. 
  Read http://docs.djangoproject.com/en/dev/howto/static-files/ for a full
explanation. If stay in doubts after reading, let us know.

custom methods

[Slammer]

FYI, I'm a beginner,  I'm having trouble with custom methods,  I'm
using an existing database which is used for a fantasy football
site,   the primary data return is a list of players for a particular
team, I've done that fine, but the score for those players is in a
different table,  So to return the list of players with their current
scores I tried to create a custom method as such in my models.py

class Player(models.Model):
p_keyid = models.IntegerField(primary_key=True)
p_lname = models.CharField(max_length=135)
#bla bla bla more fieldnames
...


def ptot(self):
from django.db import connection
cursor = connection.cursor()
cursor.execute("""
SELECT sum(s_total) s_total from score where s_pno =
%s""", [self.p_keyid])
#return [row[0] for row in cursor.fetchone()]
#return [self.__class__(*row) for row in cursor.fetchone()]
return u'S=%s' % (self.__class(*row).s_total)

As you can see I've tried a bunch of ways to return the related score
total, none have worked.

in my views.py I have
def search_roster(request):
if 'q' in request.GET and request.GET['q']:
q = request.GET['q']
player = Player.objects.filter(p_uffl__icontains=q)
return render_to_response('search_results.html',
{'player': player, 'query':q})
else:
return render_to_response('search_form.html',
{'error': True})

in my search_results.html I have
Team Listing for: {{ query }}
{% if player %}
Found {{ player|length }} player{{ player|pluralize }}.

 
 PosName
 NFLValue
 Score
 {% for player in player %}
 {{ player.p_pos }}{{ player.p_lname }}
 {{ player.p_nfl }}{{ player.p_val }}
{{ player.ptot }}
 {% endfor %}
 

{% else %}
No players matched your search criteria.
{% endif %}

My questions are this,  when I just want a single field return for a
custom method how do you form the return statement,  in my case I'm
wanting what ever I alias the sum of s_total.   After which how does
that value get successfully called from the html template.  All of it
works but I never get a return value

or is there an easier way to do this?  thanks in advance

Re: Sourcing java script file inside django

[cootetom]

Hi, django doesn't deal with static files. Your web server must serve
static files. You can read about how to use static files whilst in
development in the documentation 
http://docs.djangoproject.com/en/dev/howto/static-files/

total newb question with custom save()

[Matt]

hey folks,

I have two models:
___
class contentcreator(models.Model):
name = models.CharField(max_length=50)
phone = models.CharField(max_length=60, blank=True)
supervisor = models.CharField(max_length=60)
department = models.CharField(max_length=60, blank=True)
def __unicode__(self):
return self.name

class Meta:
verbose_name = u'Content Creator'
verbose_name_plural = u'Content Creators'

class accuracyreport(models.Model):
byline = models.ForeignKey(contentcreator, related_name="byline")
date = models.DateField()
resolved = models.BooleanField("Resolved?", help_text="Has the
issue been resolved?", null=True)
responsible = models.ForeignKey(contentcreator,
related_name="ultimately_responsible", blank=True, null=True)
supervisor = models.CharField(max_length=60, editable=False)

def save(self):
if not self.responsible:
self.supervisor = contentcreator.objects.get
(name__exact=self.byline).supervisor
else:
self.supervisor = contentcreator.objects.get
(name__exact=self.responsible).supervisor
super(accuracyreport, self).save()
___

The custom save(), as you can probably tell, is where I'm having
trouble.

I'd like to set things so that when the "responsible" field is blank,
the supervisor of the byline gets saved in the accuracyreport model.
If it's filled in, then the supervisor of "responsible" gets filled
in.

I'm aware of the denormalization issues, but I think it's the best way
to handle this particular problem.

Help?

Unicode [i]regex + sqlite3

[matevzb]

I've run into a strange problem using Django's [i]regex search with
non-ascii characters.
I'm using the [i]regex in the following manner:
 begin code 
class Tag(models.Model):
  def __unicode__(self):
return self.keyword
  keyword = models.CharField(max_length=64)

kwlist = [some list of keywords]
tag_query = Q()
for k in kwlist:
  rx = r'\b' + k + r'\b'
  tag_query = tag_query | Q(keyword__iregex=rx)  # or keyword__regex,
neither works

for t in Tag.objects.filter(tag_query):
  print t
 end code 

When a Tag's keyword *begins* with a non-ascii character (e.g. in my
case \u010d, which
is "latin small letter c with caron"), the [i]regex lookup fails for
some reason.
The strange thing is that there seem to be no problems with words
containing such characters
elsewhere, i.e. not at the beginning of a string. I've also tried the
following:
- Q(keyword__iexact), works OK
- modified regex: r'\b.*' + k[1:] + r'\b' works OK, but obviously may
return many false positives
- modified regex: r'\b.' + k[1:] + r'\b' doesn't work(?)
- python's re.search() works OK on such strings

Is this a known issue with Django + sqlite3 combination? I've seen the
docs mention that
iexact might be problematic, but that one actually works fine.

I'm using Django 1.0.2 with sqlite3 3.4.0 and python 2.5.1 (Mac OS X
10.5).

Sourcing java script file inside django

[Hrishikesh Dhayagude]

Hi,
I've recently started using django. I want to source a java script
file inside django. For that, only specifying it in script tag is
sufficient or do we need to write anything more.
If i want to source abc.js then
 
I tried doing that but was unsuccessful
When i click view page source info after right clicking..  this abc.js
is seen as a link
When i click on it then its source code should be seen but what i get
is an error saying the url doesn't match any of those in urls.py.
So do i need to include any action to be performed on that particular
url in url.py??
Thank you in advance..

Regards,
Hrishikesh Dhayagude

I use Komodo Edit (free), and am thinking of perhaps getting Komodo IDE

an X server :-/

When I'm not using Komodo, I use Vim, and Komodo has Vi key bindings for
most basic operations. I'd try emacs, but Vi found me first, and I can only
store so many arbitrary, inane keystroke shortcuts in my brain ;-P

Having Trouble with Reverse method

[Streamweaver]

I'm having trouble understanding the output of the reverse method.

I have the following URL pattern:

urlpatterns = patterns('dwrangler.project.views',
(r'^in_development/$', 'summary_in_development'),
)

from the documentation I would think I can get the URL by using

reverse('dwrangler.project.views.summary_in_development')

But I keep getting a NoReverseMatch error.  I have tried several
different formats but keep getting similar errors.

I must be missing something obvious and would be thankful if something
could point me in the right direction.

Thanks

Managers in admin

[Alasdair]

I've defined a custom manager

class Entry(models.Model):
[...]
live = LiveEntryManager()
objects = models.Manager()

so that when I use _default_manager.all() it uses the LiveEntryManager
().

However, the django admin is now also using LiveEntryManager. How can
I get the admin to use models.Manager, while keeping LiveEntryManager
as the default for everything else?

(I'm using django 1.1)

If that's really what you have, try, instead:

a = settings.My_OWN_VARIABLE=2

(note the "s" on the end of "settings".)

Re: formatting dates for DateTimeField()

[Gonzalo]

Hi Daniel, thanks for your reply apologies for the muddled question.

What I need to do is the following:

I receive a piece of data from the serial port, determine node and
timestamp it.
then when I receive the next piece of date form the same node I
timestamp it and determine the time difference form the previous
reading.

Before using Django I was timestamping data with:

time_start = time.strftime( '%Y-%m-%d %H:%M:%S' )

and computing time difference with:

time_difference = int( time.mktime( time_end ) - time.mktime
( time_start ) )

that didn't work with django because of the format required by
DateTimeField()

now I'm doing:

>>> time_start = datetime.datetime.now()
>>> time_start
datetime.datetime(2009, 9, 8, 15, 46, 9, 544688)
>>> time_end = datetime.datetime.now()
>>> time_end
datetime.datetime(2009, 9, 8, 15, 46, 32, 353081)
>>> time_diff = time_start - time_end
>>> time_diff
datetime.timedelta(-1, 86377, 191607)
>>> print int(time_diff)
Traceback (most recent call last):
  File "", line 1, in 
TypeError: int() argument must be a string or a number, not
'datetime.timedelta'

how would you compute the time_diff between the two  datetime.datetime
objects?

Thank you,

Re: automatic initialization of sample data

[Bill Freeman]

Jan,

Well, do you want this to happen every time that the module is imported?  Or
spend time
each server start determining that these items are already in the data base
and skipping
the initialization?  If not, then you're stuck telling the system when to do
this anyway (perhaps
a syncdb extension that does them if it has to create the database?).

You do realize that having initializers as default arguments, that they
consume virtual memory
forever, whether the database is already loaded or not.  That isn't
significant for loading 3 rows,
as in your example, but I presume that you're actually loading a much larger
set.

I typically have a CSV file, or a pickle of a list of dictionaries, and use
csv.DictReader or cpickle.load
in a loop that creates a model instance, populates such fields as have keys
in the source, and saves
the instance.  I think that it's less work than figuring out how to
configure some extension, and if you
let it be driven by the keys present, the code is pretty generic (at least
for the pickle; with the CSB
you typically want to convert some strings to ints, floats, and bools.  You
can also use XML, but I find
it more complicated, though attributes could control conversions.)

I've taken to putting that code in a separate load.py file, so that even the
code isn't loaded in the
server.  You could also just hand code a list of dictionaries in such a
file.  I still wind up running the
code from the manage shell, though you could certainly create, for example,
a view that imports the
load.py only if the view is referenced (by someone with enough privelege),
and runs the code.  Or
you could figure out how to attach it to syncdb.

But you should probably look at fixtures.  I haven't, as yet, but should.
They seem to be a supported
means of initializing a database.

Re: apache2+mod_wsgi: 403 Forbidden

sorry, I messed up!

I'm not sure now, i couldn't test it, but maybe you should set the Directory
directive in the specific path where wsgi files are


   Order Allow,Deny
   Deny from all


   Order Allow,Deny
   Allow from all

haml + sass + django

[ThinRhino]

Hello,

I just came across haml and sass, but looks like it is built for Ruby on 
Rails.

Any implementation that can work on Django?

Though I also came across http://bit.ly/3el7iR, by which apache can take 
care of converting haml to html.

Was looking for something where django can take care of the nitty-gritties

Cheers
ThinRhino

Re: psycopg2.OperationalError: FATAL: role "root" does not exist

[Angel Cruz]

That is another forum and postgresql question, and they provide fantastic
documentation:
http://www.postgresql.org/docs/8.1/static/sql-createrole.html

I use pd-Admin tool myself to totally control the database.
I would suggest think you make sure you are able to play around with the
database first creating tables, assigning values, etc.  (via psql or
pg-Admin) with the user you have created before dealing with django.

You should use Directory with the real path, not the alias


   Order Allow,Deny
   Deny from all


   Order Allow,Deny

like in the example :)

I do something similar one site, but both have parent directory that holds 
misc data and the project dir, example:

staging/
   apache/
apache scripts and custom conf files specific to this deployment
   myproject/
...
misc_stuff/
scripts specific to this deployment
live/
apache/
scripts and custom conf files specific to this deployment
myproject/
...
misc_stuff/
scripts specific to this deployment

Both are checked out from the same svn (instead of git) repo.  Staging of 
course is where I edit and make changes to the code for live and commits are 
from stage. While live is a read only checkout. 

For project settings, I use a settings.py and a local_settings.py file,  
local_settings.py is not in revision, as where settings.py is, and lives in my 
project directories. It holds deployment specific paths, required variables 
and info. settings.py holds info and variables that are constant across 
deployments (dev, qc/staging, live).

I've written up this the other day for a friend to learn to use 
local_setttings.py file with settings.py.  I apologize for spelling/grammar 
errors and lack of styling on the pre tags (where the code is), this is a 
problem in the middle of being fixed, rewriting this site from the ground up.  
My personal site does suffer for a lack of attention to it for a couple years.

http://gufymike.com/archives/detail/18/1/


With this setup I don't need to worry about much in terms of conflicted module 
names in the project, you just set the correct paths in your scripts that set 
the sys.path, media directories and so on.

Hope this helps,

Mike

I had a little difficulty with the Python docs on this one too. As it turns
out it's really simple. Put the following line where ever you want a break
point.

import pdb; pdb.set_trace()

The Django dev server window will stop with a Python command line prompt
right there and you have access to all of the context the current code in
the application has. It's extremely handy for testing different variations
of a given line and that the context is what you expect.

Another function I use all the time at the Python command line is dir().
Pass any object or property into it and it will list the available
properties and methods. This in combination with pprint() that formats list
output in a tree view style. I usually import pprint like so from the
command line: from pprint import pprint as pp. Then you can do:
pp(dir(object)) or pp(dir(obect.property))

I hope this helps.

Re: multi-table inheritance - how to access child object methods/attributes

[Jan Ostrochovsky]

Ugly workaround:

class Document(models.Model):
pass
def __unicode__(self):
if self.accountingdocument:
return self.accountingdocument.__unicode__()
else:
return self.__class__.__name_ + ' ' + self.id_

But I'd prefer solution, where Document class does not know about its
child classes (AccountingDocument, etc.). Any idea?

Deployment on same server: Conflict staging/production

[Benjamin Buch]

Hi,

I'm working on a small project
trying to get used to the development/staging/production setup.

I develop on my local machine,
push to a git repo
and pull from there to staging and then finally to production.

My problem here is that the staging and the production projects are  
deployed on the same server.
Thus, the project folders can't have the same names -
the production folder is called say 'myproject', so the staging folder  
has to be called different, say 'myproject_staging'.

Of course I run into conflicts here -
many imports in my code plus settings.py (INSTALLED_APPS, ROOT_URLCONF)
refer to 'myproject' - and not to 'myproject_staging'.

How can I work around this?
Is it time for me to have a look at virualenv?

Using the login page AND RemoteUserMiddleware depending on user?

[Adam Stein]

Couldn't find anything regarding this.  All authentication schemes seem
to assume you are only doing it one way.

Using Django v1.1.  I need the Django admin to come thru the login page
as normal.  However, every other account is authenticated by an external
authentication source.

I can use RemoteUserMiddleware for the external authentication, but then
I can't log in as the Django admin (since RemoteUserMiddleware ALWAYS
gets the user name from REMOTE_USER).  Anybody deal with this before?
It's easy enough to subclass RemoteUserMiddleware, but how do I tell
when to use REMOTE_USER and when to use what user is already set to?

Django settings function object?

[Maksymus007]

I tried following code

from django.conf import settings

...


a = setting.MY_OWN_VARIABLE=2

I get error

'function' object has no attribute 'MY_OWN_VARIABLE'

when I

print settings

it says its function object - instead of LazySettings object. I tried even

from django.conf import settings as something_that_cannot_make_collision

but result is the same.

Any idea why and how to fix?

ThinRhino,

Unfortunately, no. Only SVN (with subversion and/or pysvn) and CVS.  The good 
news is that these utilize Eric4s VCS api and mercurial support can be added 
as a plugin, CVS support is through a plugin.

Quick look through the docs pointed me to this file:

http://die-

Which provides an ABC that you can subclass, check out thie CVS plugin for an

The actual docs in Eric4 are here, they are actually pydoc style html files. 

http://die-

A quick search showed me this is the best and fastest way to learn how to add 
VCS plugin support for other systems.

In some places here you are using the term 'unicode' where non-ASCII would
be more correct.  The emails your code is handed, for example, contain
non-ASCII characters.  These emails are not packaged as Python unicode
strings (they cannot be, if they are coming from outside Python), they are
bytestrings.  In order to successfully turn them into unicode objects the
correct encoding of the email bytestring must be known.  The exception you
include below shows Django attempting to convert an email bytestring into a
unicode object, assuming the bytestring is utf-8 encoded.  This is failing,
so apparently the email bytestring is using some other encoding.

Python/Django handling unicode "transparently" is a bit of an optimistic
hope.  Python has unicode support, and what Django attempts to do is take
bytestrings at boundary points and convert to and from unicode objects so
that your application code never has to deal with bytestrings but rather
always has unicode strings.  So Django will convert bytestrings from the
database and bytestrings from web clients and convert them to unicode before
handing them to your application code.  Similarly it will accept unicode
from your application and convert to bytestrings for sending outside the
boundary (back to the DB or out as a client response).

Django does not require, however, that your application only use unicode
strings -- you are free to hand Django functions bytestrings.  When given a
bytestring, though, Django has to make some assumption about what encoding
the bytestring is using.  The problem with bytestrings is that they do not
carry around with them any encoding information.  What Django does when
handed a bytestring is assume it utf-8 encoded.  If your application hands
Django a bytestring that is not utf-8 encoded, you'll get errors like the
one you include below.

Someone else responding on this thread mentioned BeautifulSoup fixing
problems like this.  My understanding (I don't have time to verify at the
moment) is BeautifulSoup either detects encoding by examining the bytes and
guessing what the proper encoding may be, or trying different encoding until
one works.  Django does not do this -- it simply assumes if your code hands
in a bytestring that it is utf-8 encoded.  Thus if you have non-utf8 encoded
bytestrings you are dealing with (as you apparently do) you will need to
convert them to unicode before handing them to Django.

That, of course, just pushes the problem back onto you, and you will have to
now figure out what encoding these things are using.  Perhaps someone on
this list can help with that, but you haven't provided enough information to
really help here.  All you have said is that your app is "handed emails".
All I can tell you about those emails, based on the traceback below, is that
they are bytestrings and they are not utf-8 encoded.  If you show some of
your code that is receiving the emails perhaps someone can provide more
guidance on how to transform the email bytestrings into unicode.

Your question doesn't make sense. As you say, the docs say it should
be a datetime.datetime object. What does format have to do with it?

But you've ignored the bit that you quoted above! Why are you using
time instead of datetime? Why are you converting the time into a
string instead of a datetime object?

time_start = datetime.datetime(2009, 9, 8, 11, 15)

 @Jason - I think that's the number one reason I'm going to PostgreSQL. I
don't use everything all the time but I really like to have the widest array
of query syntax options. MySQL is just too limiting, especially when
PostgreSQL is available.

@Jano - Interesting post that you linked to. I've not see the same problems,
though I'm not dealing with external data. I'm currently working on an
internal app that will be used in Portuguese, thus dealing with UTF-8
everywhere and MySQL seems to be consuming it fine. Tho it can get a little
tricky in Python code when it comes unicode characters.

formatting dates for DateTimeField()

[Gonzillaaa]

Hello I'm importing data into django and using its admin interface to
browse and search for data.

Each piece of data is timestamped by me at log time. The docs say data
on a DateTimeField() should be a valid datetime.datetime object but I
am unclear of format (tuple, string etc..)

My model looks like this:

class InfrarredTimes(models.Model):
loc_id = models.ForeignKey(Location)
node_id = models.IntegerField(db_index=True)
pin_id = models.IntegerField(db_index=True)
time_start = models.DateTimeField()
time_end = models.DateTimeField()
time_difference = models.IntegerField(db_index=True)


so to log into that I'm doing this:


def log_status_change( self, node_id, pin_id, status ):
   '''logs a change of status for a given node into the
database'''
   if __debug__: print "Loggin status change node_id %s, pin_id
%s, status %s" % ( node_id, pin_id, status )
   loc = self.get_node_location( node_id )
   time_start = self.nodes[node_id]['reading_time_start'][pin_id]
   time_end = time.localtime()
   #time difference expressed in seconds
   time_difference = int( time.mktime( time_end ) - time.mktime
( time_start ) )

   print " loc_id %s, node_id %s, pin_id %s, time_start %s,
time_end %s time_difference %s " % ( loc, node_id, pin_id,
time.strftime( '%Y-%m-%d %H:%M:%S', time_start ), time.strftime( '%Y-
%m-%d %H:%M:%S', time_end ), time_difference )

   data = InfrarredTimes( loc_id = loc, node_id = node_id, pin_id
= pin_id, \
   time_start = time.strftime( '%Y-%m-%d
%H:%M:%S', time_start ), \
   time_end = time.strftime( '%Y-%m-%d %H:
%M:%S', time_end ), \
   time_difference = time_difference )
   data.save()
   return True

this is not working at the moment. any pointers much appreciated.

Question on multi-table inheritance docs

[Egon Esser]

Hi!

Please consider
http://docs.djangoproject.com/en/dev/topics/db/models/#inheritance-and-reverse-relations

I'm a total failure at understanding this part:
"you must specify the related_name attribute on each such field"

In a Restaurant instance, wouldn't you access the Supplier instances
(that are M2M'd from the Supplier model) via supplier_set?
I.e., as explained here:
http://docs.djangoproject.com/en/dev/topics/db/queries/#many-to-many-relationships

At which point does that clash with the inheritance stuff?

TIA!

Re: Error in setting up psycopg2

[Jan Ostrochovsky]

Hi Simon,

I had also problems with psycopg2 on Mac OS X. First with development
server (python manage.py runserver), and when solved, later also with
Apache.

Finally I decided for Linux on production server (with Apache), and
let Mac OS X on development workstations (with runserver).

If such setup is suitable also for you, maybe these howtos will be
also useful:

If you will need some support with Linux or PostgreSQL, do not
