Re: Password Logistics Help Needed

[Bryan Veloso]

Alright. I tried looking in the actual source for any mention of
password_md5... and it no longer exists. So I'm sure I just can't call
the field. I'd have to recreate it or something correct?

Edit inline problems

[Patrick Anderson]

Hi! It's been a while since I posted to this list, but I have a little 
problem and would like to ask for some help.

I have the following 2 models:


class Personnel(models.Model):
report  = models.ForeignKey(Report, unique = True)

class Admin:
pass


def __str__(self):
return 'Personnel list from (%s)' % self.report


class Person(models.Model):
personnel = models.ForeignKey(
Personnel,
core = True,
edit_inline = models.TABULAR,
min_num_in_admin = 1,
max_num_in_admin = 10,
)
first_name = models.CharField('F. Name', maxlength = 25, core = True)
middle_name = models.CharField('M. Name', maxlength = 25, blank = 
True)
last_name = models.CharField('L. Name', maxlength = 50)
date_born = models.DateField()
time_added = models.DateTimeField()


def __str__(self):
return '%s %s' % (self.first_name, self.last_name)


I validate the models and I can see the forms in the Admin, but every 
time I try to add a Person (while adding a new Personnel list or editing 
an existing one), none of the Persons get saved. What could be wrong with 
my model?

I'd appreciate your look at it and pointing any errors I might have in my 
code. Thank you!

Patrick

Awesome, well I'm already extending the user model, so I can just add
that. So password_md5 still exists? Sweet, if so, I can just override
save() and have that save in the account table right? Things are
looking a lot clearer now, thanks Nimrod.

I've seen it happen as well, always on model classes. I need to check
a newforms form and see if the same happens to them.

Looks like this is the default result for Model subclasses. Possibly
related to the way we create them (using a metaclass). Feel free to work
out a patch in django/db/models/base.py (in the ModelBase class,
probably) if you want to fix this. It would probably be useful.

Otherwise, might be worth opening a ticket in case somebody else is
looking for something to do.

Given the complete lack of example code you've provided, we have no way

If it says "0.96-pre" you aren't using the development version. You are
using something from before the last release. However, even if you made
a typo there and are really using 0.97-pre, there are no known huge bugs
in the form handling code. Lots of people are using the development
version. You are using some code that is at least a month or two old,
though, since FloatField no longer takes max_digits and decimal_places
in trunk.

I have no guess as to what is going wrong here .You're just going to
have use normal debugging techniques: put print statements into the
code, for example and check that things are the types they should be.
Read the Django source where it is failing and work out what it is
expecting. Reduce your problem case to an example that is as small as
possible so you don't have to worry about extra stuff getting in the
way. Things like that.

You are getting some fairly explicit error messages, so working out what
is trying to call save() on a form field (and why) is going to go a long
way towards solving this.

Re: multiple databases

[benf]

Hi Guys,
I'm in the middle of the latest set of updates (the merge of the
oracle branch with trunk), the only thing left to do is sort out the
core.management module (68 conflicts!!). I should have that cracked by
the end of today and it would be great to get it checked in so others
could help with the testing... For some reason the tests are freezing
my shell on my development machine! All of the changesets thus far
have been done in an incremental way using a mirrored SVK repo, so I'm
hopeful that I can commit them in a granular way too. If necessary I
can make a patch against trunk, if commit access is problematic,
although obviously we would lose all the log information if we did
that.
Let me know,
Ben

You can find docs about em here.

In my understanding, the Apache configuration would have the same

The usual route I go with when trying to extend on the User model is
to create a new model and link it to the User model. For example:

class UserExt(models.Model):
user = models.ForeignKey(User)
# ... other fields that you need here

def __init__(self, user):
self.user = user
# ... other stuff that you need to do here

# ... other methods you need here

In your case, you can just create a UserExt model, add a password_md5
field, set that field when creating or updating a user record and save
the user_ext object.

HTH.

pydoc problem

I have a models.py module that I thought I would test pydoc on. So I
try.

Help on class Merchant in module mysite.models:

Merchant = 



but this isn't the doc string I have for this class at all and isn't
what you normally get from pydoc. I try a few more of the classes with
the same result. So I copy one of those classes to a new class in the
same module (just adding the number 2 to the name) and it works
perfectly for that class. Obviously something somewhere else is
different but what?

Yeah. As you've discovered, one of the big points of newforms-admin is
to get as much stuff as possible out of the model -- it doesn't really
belong there, and that's why you use a ModelAdmin class and register
with an admin site.

Re: Custom admin field widgets in the newforms-admin branch

[leif strickland]

After some digging around, it looks like the newforms-admin branch
does not allow widget declarations within the model class itself.
However, adding a custom widget is quite easy.

In the branch, almost all of the admin app functionality has been
moved out of the inner Admin class and into a separate class called
ModelAdmin. If you want to customize the admin app's behavior, simply
subclass ModelAdmin and override the default functionality.

For example, look at this sample ModelAdmin subclass:

-

from django.contrib import admin

[...]

class ProfileOptions(admin.ModelAdmin):
list_display = ('display_name', 'headline','setup_date')
filter_horizontal = ('techniques', 'products', 'setup')
fields = (('Administrative Settings',{'fields':
('subscriber','active')}),('Contact Information',{'fields':
('phone_numbers','im_accounts','zip_code')}),('Photos',{'fields':
('primary_photo','secondary_photos','private_photos')}),)

def formfield_for_dbfield(self, db_field, **kwargs):
if db_field.name == 'zip_code':
return ZipCodeField(**kwargs)
else:
return 
super(ProfileOptions,self).formfield_for_dbfield(db_field,
**kwargs)

def queryset(self, request):
return self.model.user_profiles.get_query_set()


adminsite.register(Profile,ProfileOptions)




list_display and fields are used exactly as they were in inner Admin
classes. filter_horizontal is simply a tuple of fields that will use
the javascript multiple-select filter.

The queryset() function allows you to specify which manager should be
used to obtain the change list objects.

Then there's formfield_for_dbfield(), a function that allows you to
override the default form field types that are returned for your
models' fields. In this example, the function returns a custom field
class (ZipCodeField) for any model field named "zip_code".

Alternatively, you could specify a custom widget like so:

if db_field.name == 'zip_code':
kwargs['widget'] = WIDGET
return 
super(ProfileOptions,self).formfield_for_dbfield(db_field,
**kwargs)

Finally, don't forget to register your ModelAdmin subclass for the
model.

You can find more information on the branch's homepage:

http://code.djangoproject.com/wiki/NewformsAdminBranch

I hope this helps! If I am wrong about any of this, please post so
others don't repeat my mistakes.

Cheers,
LS

Re: admin forms lose javascript with mod_python

thanks for both of your replies. I used wireshark (previously known as 
ethereal) to follow the HTTP stream (being a low-level type of guy, i 
tend to use low-level type of tools :) ). Saw that the js files were 
returning 404's, even though the css's weren't...

It turns out i made a mistake in the apache/mod_python config. Because i 
serve multiple top-level urls from django, i use LocationMatch instead 
of Location, like so:

 SetHandler python-program
 PythonHandler django.core.handlers.modpython
 PythonInterpreter wwd
 SetEnv DJANGO_SETTINGS_MODULE wwd.settings
 PythonDebug On
 PythonPath "['/var/www/django','/var/www/django-projects'] + sys.path"


well, the regex also catches, e.g., /media/js/admin/DateTimeShortcuts.js
even though media is normally served statically. It doesn't catch the 
css media, though, because it's not in admin. Changing the regex to this:


solves the problem nicely.

PS: i use apache+mod_python simply because i have a few other apps that 
are raw mod_python, so i need apache+mod_python anyways - i might a well 
use it for django, too.

If I understand you correctly, just have local lightty running and
edit /etc/hosts to resolve foo.com to (or whatever lightty is
listening on).

I'm pretty sure they'll be updated to newforms, but to be clear, your
choices are to either use what's there and works for now (with likely
migration in the future), or roll your own for sure right now.

I'd use what's there.  ;)

nested function

[dailer]

I created a validator for use in a validator_list in the admin
interface like so...

def startDate_EndDate_CrossValidation(modelName):
def result(field_data, all_data):
  


 being new to python, I stole this from an example somewhere. I have
these 3 attributes, but how do I call this? I tried following the
django code, but it's a bit over my head at this point.

admin and .FileField()

[Carl Karsten]

Took me a bit to get .FileField() working in the admin, and im wondering if it 
needs to be as complicated as it seems.  I think it currently violates DRY, and 
maybe that was intentional for 'security' or 'performance' reasons, or maybe it 
was just an oversight.

I did the following, and got the following.

[EMAIL PROTECTED]:~/django$ django-admin.py startproject filez
[EMAIL PROTECTED]:~/django/filez$ ./manage.py startapp pics

DATABASE_ENGINE = 'mysql'
db, user, pass ...

INSTALLED_APPS = (
 'django.contrib.admin',
 'filez.pics',

# models.py
from django.db import models
class File(models.Model):
 attachment = models.FileField(upload_to='attaches', blank=True )
 class Admin:
 pass

# urls.py
 # Uncomment this for admin:
  (r'^admin/', include('django.contrib.admin.urls')),


http://dell29:8000/admin/pics/file/add/
Give it a file name (text box or browse button) hit Save.
(it will create the attaches dir.  not sure if that is a good thing or not. 
personally I would rather it error, but at least it makes it obvious where the 
dir 'is'.)

http://dell29:8000/admin/pics/file/1/
source:  attaches/P1010001.JPG 

which is:
http://localhost:8000/admin/pics/file/1/attaches/P1010001.JPG
click that, get

404, Using the URLconf defined in filez.urls, Django tried these URL patterns, 
in this order: ...  The current URL, admin/pics/file/1/attaches/P1010001.JPG, 
didn't match any of these.

As in, it can't find where it put it.  Seems to me the default should be to be 
able to figure that out.  With some help from #django I did get it working, but 
it didn't seem 'right.' so I figured I would throw up a flag and see if anyone 
thinks some tweaks need to happen, or point to the docs that show me how to do 
this the easy way.

Re: Announcing the birth of Fluther.com

[leif strickland]

Looks great. Good work!

For those of us still stuck in alpha, can you share a bit about your
implementation? Are you using Apache? Squid?  What's your approach to
caching? Did you use Django's built-in User model for your registered
site users? What DB did you opt for?

Any information would be a great help to all the Django newbies. Plus,
you might get some valuable feedback from the pros on this board.

Again, congrats!

Re: Zip code lookup field

[leif strickland]

I figured it out!

The problem was that my custom zip code field's clean() function was
returning the profile object's *id*, not the actual zip code
instance.

>  zip_code_id = Postal_Code.objects.get(postal_code=value).id
>  return int(zip_code_id)

As it turns out, the function should have returned the actual object.
All I had to do to make this code work, therefore, was remove the
".id" from the end of the first line above. Voila!

Lesson learned: Custom fields for foreign keys must return an
instance, not the key.

Thanks again for the help. Hope this thread helps someone else in the
future.

Cheers,
LS

Re: Password Logistics Help Needed

[Bryan Veloso]

Alright, I did about 2 hours of searching today and I'm beginning to
think that the above is an impossibility. Which probably means that
I'm going to have to bypass Django authentication and make my own, but
I don't even know where to start on that, so I'm at quite a loss. :/

Re: Best way to link to other pages in templates

[Ryan K]

Anyway I'd also like to add that having built my first real
application with Django I'm awestruck at how easy it is to use. I
spent more time picking colors that looked good together than I did
coding site logic. On top of that, the source of the package is easy
to read and which makes up for the documentation (which has gotten
better though).

lightTPD, local ref to static files

[[EMAIL PROTECTED]]

Hi,

I have a lightTPD setup. Assume my django project is foo located at /
home/foo, the document root is in /home/foo/public_html, and the
django templates are in /home/foo/templates.

I've configured lightTPD as follows:
===
fastcgi.server = (
"/django.fcgi" => (
"main" => (
#"socket" => "/home/foo/django.socket"
"host" => "127.0.0.1",
"port" => 3033,
   )
 ),
"/admin.fcgi" => (
"admin" => (
#"socket" => "/home/foo/admin.socket"
"host" => "127.0.0.1",
"port" => 3034,
   )
 )
)
alias.url = (
"/media/" => "/usr/lib/python2.5/site-packages/django/contrib/
admin/media/",
)
url.rewrite-once = (
"^(/media.*)$" => "$1",
"^(/static.*)$" => "$1",
"^/favicon\.ico$" => "/media/favicon.ico",
"^(/admin/.*)$" => "/admin.fcgi$1",
"^(/.*)$" => "/django.fcgi$1"
)
===

Note that static listing in url.rewrite-once.

I want to put my javascript, images, and css in public_html/static.
The problem seems to come with the templates. I want to be able to say
.

But that seems to want to look in /home/foo/templates/myView/static/
img.jpg.

That sucks. I don't want to have to say . I also don't want to say  when developing locally.

Any solutions?

By the way, my .com already exists, so it would be a nice if I could
develop locally and use the former (foo.com/static/img.jpg) rather
than use localhost. I should be able to configure my lightTPD to do
that, right?

Thanks!

ManyToManyField: help_text missing when using filter_interface

[Carlos Hanson]

Greetings,

When I use a filter_interface for ManyToManyFields that have help_text
set, the help does not show up in the admin interface.  I have started
to dig into the Javascript that makes the change for the select box,
but hopefully someone can identify the problem more quickly than I.

The other thing I noticed while researching the problem.  In the
documentation on "Customizing the Django admin interface", the Labels
section says, "Any explanation or help text should follow the label in
a p with class .help."  In the source code of the rendered page
without any customization, the help_text shows up at the end of the
"form-row" div tag rather than after the label.

I am using version 0.96 on SuSE 10.1 with Python 2.4.2.

Thanks.

Carlos Hanson

Hello Fellow Djangoers!

After many late-night IRC sessions and countless visits to the django
docs, we're very proud to announce the launch of Fluther.com, our
Django-powered social Q site.

Yes, it's similar to Yahoo Answers or AskMeFi, but with some new
twists like real-time discussion, questions filtered for you, and IM
integration.

Now that we have finally completed it we're climbing out from our cave
and wondering if the site can fly, and how we help attract people to
it.

Any comments or advice?

I guess it might make sense to return the "add" url instead, although that
makes it twice as much code. I don't think that's an issue for me (yet).

As for whether it should be part of models.Model, I'm not particularly
bothered either way, but in favour are :
1. The fact that it doesn't require any info outside the model itself,
2. The fact that I'm not the only person who found a need for it - Nathaniel
has one, and he credits wamber.net.
Against is the corner case you mention, of course.

I suppose I should add it to trac to let the experts decide.

Chris

Right but I'm using the Django server included with the package for

mydjangosite, but for my deployment server its /~ryan/...etc..etc
I just put a LINK_PREFIX string in the top settings module and a

this setting along with any other extra context stuff for use with

Hmmm. Nice, except that it hardcodes the base url of the admin, which leads
me to this :
def get_admin_url(self):
pk = getattr(self, self._meta.pk.attname)
return ('django.contrib.admin.views.main.change_stage',
(self._meta.app_label,
 self._meta.module_name,
 pk))
get_admin_url = models.permalink(get_admin_url)
Does that look reasonable?

Looks like something that could be part of models.Model...

django.contrib.auth.views

[rycole]

I'm beginning a site with Django, and am starting with the fundamental
elements of the site first. I figured I'd get the user login /
registration working before I do anything. Should I still use
django.contrib.auth.views for login, logout, etc, even though they use
oldforms? Or, will these views stay backwards compatible through
future versions? These views provided by auth are exactly what I need,
but I don't want to use them if I will need to change stuff later. Any
ideas?

Thanks

Re: Zip code lookup field

[leif strickland]

Yes, the ModelAdmin is registered with django.contrib.admin.site. And
the change and add pages for the model are displaying correctly. It
even provides the expected error message if I enter an invalid Zip
code.
But when I enter a correct Zip code and Save, it gives me an
Integrity

Again, you may want to str() .postal_code if it's numeric.

Are you registering your custom ModelAdmin with django.contrib.admin.site?

Re: Problem with URL

[robo]

Yes, Alberto is right.

Also, I ran into this problem a few days ago. Basically, after you
write your view processing like Alberto suggested, you need to do a
response redirect or HttpResponseRedirect and pass it "." (which is to
the same page the user was on). After I did that on my form, the user
gets sent back to the same page and the "." eliminates concatenating
another useradd string to the end of your url.

Have fun.

gettatr() access to ManyToMany huuuge delay?

[grassoalvaro]

Here some code:
-
class TestField(models.Model):
name = models.TextField()
text = models.ManyToManyField(TextOption)
class Meta:
db_table = 'test'


test = TestField.objects.get()
a = time.time()
for i in range(0, 1):
t = getattr(test, "text")
print "text: %f"%(time.time()-a)
a = time.time()
for i in range(0, 1):
t = getattr(test, "name")
print "name: %f"%(time.time()-a)


text: 1.149759
name: 0.017819
-

Can someone explain me, why when i'm doing gettatr(test, "text")
(ManyToMany) i have so long delay? That is django (not database)
problem but i really don't know why. Anyone?

Re: Method to find the admin url for an object

[Nathaniel Whiteinge]

Not sure if this is what you're looking for, or if there's an official
way to to this, but I'm using this::

def get_admin_url(self):
return "%s/%s/%s/%s/" % ("/admin", self._meta.app_label,
self._meta.object_name.lower(), self.id)

Stolen from wamber.net.

Re: Zip code lookup field

[leif strickland]

OK, I've been tinkering with this all day, and I'm still having one
big problem
As Jeremy suggested, I created custom ZipCodeField and MyAdmin
classes. In addition, I created a custom ZipcodeLookupInput widget.

I've tested this in the shell and on the test server, and the clean
and render functions appear to be working beautifully. The widget's
render() function looks up the initial value (the zip code id) and
uses the corresponding zip code as its display value, and the field's
clean() function converts the user-provided zip into an id and
returns
it as an integer value.

Unfortunately, I keep getting an error when I try to save. It appears
that the zip_code_id is None by the time a DB query is attempted in
django.db.backends.util. But this makes no sense, beacuse the clean()
function seems to be working properly (i.e., it returns an integer
value).

Does anyone know what might be happening?  I have pasted my custom
classes code below.

from mysite.address.models import Postal_Code
from django import newforms as forms

[...]

class ProfileOptions(admin.ModelAdmin):
def formfield_for_dbfield(self, db_field, **kwargs):
if db_field.name == 'zip_code':
return ZipCodeField(**kwargs)
else:
return
super(ProfileOptions,self).formfield_for_dbfield(db_field,
**kwargs)

class ZipCodeField(forms.fields.CharField):
def __init__(self, **kwargs):
kwargs['widget'] = ZCLookupTextInput

super(ZipCodeField, self).clean(value)
try:
zip_code_id =
Postal_Code.objects.get(postal_code=value).id
except Postal_Code.DoesNotExist:
raise ValidationError, "Please enter a valid
zip code."
return int(zip_code_id)

Re: Re-rendering same page

[Val]

Specifically, the boolean values describe certain types of data the
user wishes to mask when looking through the database.  The values are
specific to each user, so there is no reason to DB them.  I am storing
them in the session variable.  The problem is that the variables are
not updated instantly, and I was wondering why this could be.

the best practice is to use the same view to display (GET request) and
process (POST request) the form. This is shown here:
http://www.djangoproject.com/documentation/newforms/#simple-view-example

This way you redisplay the same page when the form is not valid, and
redirect to another page upon successful form submission.

If something is not clear, feel free to ask again.

This is related to this ticket: http://code.djangoproject.com/ticket/4689

Don't let the message/error intimidate you and go on with the tutorials :).

It isn't a big problem, it will go away when you set DATABASE_NAME variable
in settings.py (the next step) and it will eventually be solved so the behavior
matches the documentation again.

django.contrib.auth: 'module' object has no attribute 'get_max_name_length'

[BigBaaadBob]

New install and new user, so maybe I'm doing something dumb.  I
searched and didn't see anything...

Following the tutorial I get this when running the development server:

[EMAIL PROTECTED] ~/DjangoText/demosite $ python manage.py runserver
Validating models...
django.contrib.auth: 'module' object has no attribute
'get_max_name_length'
1 error found.

Django version 0.97-pre, using settings 'demosite.settings'

The session variable (I assume you mean request.session) is backed by
the database, fetched upon the first access and stored back at the end
of each request.

Are you serving multiple requests by the same user at the same time?

Re: Newforms Attribute Errors

[robo]

I've also tried abandoning form_for_model and created my own custom
form like so in forms.py:

from django import newforms as forms
from django.newforms.widgets import *

class OrderDetailForm(forms.Form):
  order = forms.IntegerField()
  quantity = forms.IntegerField()
  unitPrice = FloatField(label='Price', max_digits=10,
decimal_places=2)
  lineItemPrice = FloatField(label='Line Item Price', required=False,
max_digits=10, decimal_places=2)
  item = forms.IntegerField()
  size = forms.ChoiceField(choices=SIZE)
  timestamp = forms.DateTimeField(required=False)
  vendor = forms.IntegerField()

--
Then in my view:

from django.shortcuts import render_to_response, get_object_or_404
from django.contrib import *
from gfs_chefrevival.store.models import *
from gfs_chefrevival.shop.forms import OrderDetailForm
from gfs_chefrevival.products.models import *
from gfs_chefrevival.vendors.models import Vendor
from django.contrib.auth.models import User
from django.http import *
from django import newforms as forms
import datetime

  detail_form_data = {
  #'timestamp': datetime.datetime.now(),
  'vendor': vendor_id,
  'unitPrice': 5.23,
  'lineItemPrice': 1.90,
  'quantity': 1,
  'order': 1,
  'size': "M",
  'item': 5
  }

def vendor(request, vendor_name, vendor_id):
  if request.method == 'POST':
form = OrderDetailForm(request.POST)
if form.is_valid():
  form.save()
  return HttpResponseRedirect(".")

  else:
form = OrderDetailForm(detail_form_data)

--
But even using custom forms I get errors:

AttributeError at /vendor/Chef/1/
'lineItemPrice' object has no attribute 'save'
Request Method: POST
Request URL: http://192.168.1.104:8000/vendor/Chef/1/
Exception Type: AttributeError
Exception Value: 'lineItemPrice' object has no attribute 'save'
Exception Location: /www/htdocs/gfs_chefrevival/../gfs_chefrevival/
shop/views.py in vendor, line 131

This error shows up for EVERY form field in my forms.py (I've
commented out one by one).

FYI, I'm using Django's development version (0.96-pre), could this be
a problem?

Your best bet is probably to read the source right now; when the
branch is complete there will undoubtedly be documentation showing the
sorts of things you can do with it, but at the moment the code is
still under development.

There are multiple processes in general-- runserver is one process,
but shouldn't be used outside of development.

If you're setting a value you wish to be shared amongst multiple
requests, you need to put it out of process somehow.  Cache or DB are
the general answers.

Sorry for missing that the first time.  :)

Admin uses django.newforms.models.form_for_model, which takes an
optional formfield_callback in order to map between DB fields and form
fields.

In order to supply that parameter, it looks like you'll need to
inherit from django.contrib.admin.options.ModelAdmin and override
formfield_for_dbfield.  That method maps between database fields and
form fields.

Have formfield_for_dbfield return your custom field class (a subclass
of django.newforms.fields.Field; CharField might make sense), then
override the Field.clean method to do your FK lookup and raise a
ValidationError if it's not a valid zip code.

NB: I haven't used newforms much myself yet.  Please report back if
you run into any troubles.  :)

You'll end up with something like this:


class MyAdmin(ModelAdmin):
   def formfield_for_dbfield(self, db_field, **kwargs):
  if isinstance(db_field, models.ForeignKey) and db_field.name ==
'zip_code':
 return ZipCodeField(**kwargs)
  else:
 super(MyAdmin, self).formfield_for_dbfield(db_field, **kwargs)

---
class ZipCodeField(CharField):
def __init__(self, *args, **kwargs):
self.max_length, self.min_length = 5, 5
super(ZipCodeField, self).__init__(*args, **kwargs)

   def clean(self, value):
   value = super(ZipCodeField, self).clean(self, value)
   from yourmodels import ZipCode
   try:
  ZipCode.objects.get(pk=value)
   except ZipCode.DoesNotExist:
  raise ValidationError, "Please enter a valid zip code"
   return value

---
from django.contrib.admin import site
site.register(YourModel, YourAdminClass)

Re-rendering same page

[Val]

I am having difficulty with re-rendering the same template.  My site
is designed with links which, when clicked, will change a boolean
value (this is done via a query string), then re-render the page they
were clicked from.  The problem is that when the page is rendered, it
takes multiple refreshes for the value to update itself.  Is this a
problem anyone else has experienced?

Template tag render method never called

[Kevin Tonon]

Hi,

I'm using Django 0.91

More or less, this is what I'm doing:

appname/templatetags/app_extras.py:

from django.core.template import Library, Node
register = Library()

class MyNode(Node):
def __init__(self, foo):
self.foo = foo
print 'foo' * 100

def render(self, context):
print 'bar' * 100
return 'bar' * 100

@register.tag
def mytag(parser, token):
return MyNode(0)

In my template:
{% load app_extras %}
{% mytag %}

When I run this using the development server, 'foo' * 100 is printed,
but 'bar' * 100 is not. That is, it looks like render is never being
called? Is there anything obviously wrong with what I'm doing?

On another note, I tried stepping through the code with pdb, but it
was ignoring my breakpoints. I tried running the server with --
noreload too, but 0.91 doesn't seem to support that.

Any advice would be greatly appreciated, thanks.
Kevin

Method to find the admin url for an object

[Chris Brand]

In going through cleaning up all the hard-coded urls in my templates, I'm
making good use of the get_absolute_url methods that I've added to my
models.

Looking at the links I'm left with, they're almost all to the admin pages.
How would I write a method to provide a get_admin_change_url method ?

Thanks,

Chris Brand

Re: generating customized flyers (pngs or pdf)

[[EMAIL PROTECTED]]

Its been a while since I used reportlab but shouldn't he be able to
add the image and place some text on top of it without generating a
whole image with PIL and then placing it in pdf?  Of course that
assumes pdf output only and not png.  I think the best results would
be the reportlab route anyway.  It has a lot of nice formatting tricks
and handles flow very well.  Much better than trying to do it yourself
on a raw canvas.

Ahhh. So after I've used login() once in a test, get() will pass the
existing session cookie, in which case my test to retrieve two pages while
logged in would look like :
client.login(...)
client.get(...)
Does that sound right ? I'll try that later today.

Yes, I saw that. Thanks for the warning, though.

I noticed that if I add middleware ThreadLocals as per:

   http://code.djangoproject.com/wiki/CookBookThreadlocalsAndUser


even going to admin page raises that error, even if it does not seem
to be
any harmfull. Is there somebody, using ThreadLocals that does not have

same problem?

I'd appreciate both positive & negative feedbacks

Best way to link to other pages in templates

[Ryan K]

What is the best form of a link in my Django site's templates? For
example, I have a base.html which serves as the base template for all
others. It contains links that are relative to the current directory
like Manage. However, when I am at a page like
http://example.com/mydjangosite/manage/edit/23123 (editing the object
with id 23123) the same link above is instead pointing to
http://example.com/mydjangosite/manage/manage. I constantly have to
deploy this application to the main server but normally I work on it
locally, so absolute links would be a pain. Should I use templated
URLs  (e.g. Manage) for my links or
is there a better way?

This is traceback errors from interactive view:

I think it has something to do with how I'm importing. This is my

Have a look at django.conf.settings.configure:

freecomments not displayed II

[emer77]

(sorry for the bad english)

I'm with the same problem of this (closed) thread:
http://groups.google.com/group/django-users/browse_thread/thread/9930f6e624fd8363/f52bc916056d7dbd?lnk=gst=free+comments=1#f52bc916056d7dbd

Using django-svn.

In two local installations (Mac and Ubuntu), freecomments works
flawless (with "manage.py runserver").
But at the server of webfaction, they don't show up, though the code
is the same.

In the admin interface, the sum of comments appears, but the list is
empty. I checked at the phpMyAdmin: freecomments are there.

Tried drop all tables and syncdb, but it didn't work.

Any ideas?

Re: use Django's database layer for a regular python program?

[Roodie]

I worked on a console application which uses django to do some  
database related tasks.
I started my code with these lines:

---

#!/usr/bin/env python
import sys
sys.path.append('/Library/Frameworks/Python.framework/Versions/2.4/ 
lib/python2.4/site-packages/django')
sys.path.append('/path/to/the/application/directory/')

import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'applicationname.settings'

---

 From this point you can continue by importing the neccessary  
libraries and writing your code.

Maybe there is a better way of doing it but works perfeclty.

using django.contrib.auth interface

[Henhiskan]

Hi fellows,
I have doing a custom user authentication, I have my own views to
control login and logout, and works great, but now I wish use the
authentication views that Django provides.
When forms call to login view, Django authenticate user but then
redirect to '/account/profile'. Reading the source code ( django/
contrib/auth/views.py) I realized that there is a vars
REDIRECT_FIELD_NAME that is setting to redirect_to. Then I found that
REDIRECT_FIELD_NAME has a 'next' inside that I suppose that is the
name of the var that I must send inside URL. Well, I put this inside
the form, but didn't works :(
(in the login template that I have)


The question is: How can I pass the "next" vars to login view, without
hardcode
this view?

The logout view are using something similar to that, but is getting as
a parameter(next_page). So after logout, returns to a custom page
that I pass :)

Am using Django 0.95 by the way.

Cheers.-

Re: use Django's database layer for a regular python program?

[Michael K]

It's currently being done for a server application, I don't see why it
couldn't be used for a desktop application as well?

Check out http://www.silverstripesoftware.com/blog/archives/51 and
http://code.google.com/p/evennia/

The first is a desktop application that uses Django, I'm just not sure
if it's using the database backend or not.   The second is a MUD
server that uses Django for data storage as well as the web services
for MUD management.

It should be as simple as creating a new project and ignoring the urls/
views part of the code, and just importing the models as normal.

HTH,

Michael

Have you done any profiling?  I haven't compared such a port, but I'd
be surprised if performance is significantly (i.e. one order)
different without some optimization being missed.

If you have, can you point to any parts of Django that we could improve?

As presented, there's not much actionable.  "Java is faster than
Python" is not news, but I doubt the language is the problem here.

Thanks!

Password Logistics Help Needed

[Bryan Veloso]

Long story short, I'm building a control panel + backend to an MMORPG.
It runs off of a mySQL database, I used inspectdb, and all of that
worked perfectly. However, now I have some duplicate data, the User
model (since I'm using django-registration) and the account table of
the inspected database. I'm sure I could just assign the applicable
values from the User model to the account table while creating the
user's profile via profile_callback(), but the only problem I can't
seem to get my head around is the password one.

At the moment, the game can only read md5 or plain-text passwords, and
I know that Django has the hash$salt$hash (or something. :P) way of
doing it. So I can't just copy the password from the User model to the
account table since the game will choke on that data. So is there any
way I can store two sets of the password? One in the user model that
gets copied as md5 or plain-text to my accounts table?

Thanks in advance, please let me know if I have to explain things a
bit more. :)

Cheers,
Bryan V.

Re: Forms and formating error messages

In future, please remember that when you send a message like this, a lot
of us are reading it through an e-mail interface, so include the
necessary context to help us understand the problem. I ended up having
to go back and read all your earlier messages in the thread to work out
what the problem is that you were having. People, including me, may not
always feel like spending that much time to answer a question, so please
help us to help you.

If I understand correctly, you want to have control over error message
presentaiton.

[... snip...]
> [field.html]
>

> field.field.required %}*{% endif %}: label>
>

> {% if field.errors %}{{ field.errors }}{% endif %}

So this is the problem. If you look at field classes (in
newforms.fields), you can see that the errors attribute is a
newforms.util.ErrorList class and the __str__ method for ErrorList is
the as_ul() method -- displaying results as an unordered list.

If you want to control the presentation, you will need to iterate over
field.errors and write out the results one by one. Or you could write a
filter that applies to field.error and does this for you. Remember that
ErrorList is a subclass of Python's standard lists, so something like
(untested):

{% if field.errors %}
   {% for error in field.errors %}
  {{ error }}
   {% endfor %}
{% endif %}

This particular example would just dump the strings with br tags between
them, but you can obviously do whatever you want there.

Some experimentation will be required, but since you have full access to
the raw error strings, anything should be possible.

Malcolm

Re: Forms and formating error messages

[AnaReis]

Hi again,
This is getting very frustrating because I can't make this work...
This is exactly what I wrote in the files:
[newforms.py]
from django import newforms as forms
from django.newforms.forms import BoundField
from django.template import Context, loader

class TemplatedForm(forms.Form):
def cc(self):
"Helper function for fieldsting fields data from form."
bound_fields = [BoundField(self, field, name) for name, field
\
in self.fields.items()]
c = Context(dict(form = self, bound_fields = bound_fields))
t = loader.get_template('newforms/form.html')
return t.render(c)

def __str__(self):
return self.output_via_template()

[form.html]
{% for field in bound_fields %}
{% include "newforms/field.html" %}
{% endfor %}

[field.html]

  
{{ field.label }}{% if
field.field.required %}*{% endif %}:
  
  
{{ field }}
{% if field.errors %}{{ field.errors }}{% endif %}
{% if field.help_text %}
({{ field.help_text }})
{% endif %}
  


This probably has to be modified to do what I want it to do (present
the error text as simple text and not as ) but I have no idea
where I have to change this to do what I want it to do. I know that
the changes have to be made on the function output_via_template(), but
I just don't know what am I supposed to do there. :(

Problem with URL

[AnaReis]

Hi,
I'm having a problem here and I don't really know how to solve it.
I have a form on a page, the add user page:
(r'^manager/operations/nlsciadc/users/adduser/$', add_user),  #The
template is add_user.html

When the user presses submit, the action on the form sends the user
to:


This on my urls.py call the view function result_add:
(r'^manager/operations/nlsciadc/users/adduser/resultadd/$',
result_add),

If an error occurs in the form, for example, the passwords don't
match, the user is sent back to the add_user.html template:
if not form.is_valid():

return render_to_response('add_user.html', {'form':form})

The problem is that when the user is sent back to the add user page to
correct the errors, instead of going to the URL manager/operations/
nlsciadc/users/adduser/ it remains in the URL manager/operations/
nlsciadc/users/adduser/resultadd/ so when the user presses the submit
button again the user is sent to the URL /manager/operations/nlsciadc/
users/adduser/resultadd/resultadd/ which obviously isn't mapped on the
urls.py file.

The only thing I can think of is telling the user to press the back
button and fill the form again, but besides this being a lame
solution, it's much better for the user to have the filled form with
the errors next to each field and just having to correct them, instead
of having to go back and fill the form.

I don't really know how to fix this. Is there anyway in the view in
which I can call an URL in the http response? Anyone has any ideas?

You don't mention which code branch you are working with.

If you are using trunk, then non-ASCII characters are very difficult to
work with in general and not really recommended. That will soon be
corrected with the merging of the Unicode branch back into trunk.

If you are using the Unicode branch, I have not yet added Unicode
support to the Oracle backend. That will be happening during this week
sometime, as I work my way through all the details.

On the contrary, the Oracle code has now been merged into trunk and
should be very stable, although small bugs may be found over time.

cx_Oracle deploying problem

[audial]

Hello!

I've developed my project on my desktop machine ( WinXP + Python
2.4.4. + Oracle Express Edition ).
Now I have a problem with deploying it on the Gentoo Linux 2007.0
( Python 2.4.4 + Oracle 10.2.0.1 )
I don't see ANY russian chars, there are '?' (question symbols)
instead of them =(
Great problem occured after half an year of development work.
I'm not so good in python skilling, I've started from Django on it.

I have NLS_LANG = RUSSIAN_RUSSIA.CL8KOI8R parameter and also locale =
ru_RU.KOI8R
The DEFAULT_CHARSET is also 'koi8-r'

I know, that oracle-branch is not so stable, but for now i can;t go
from it, cause a great part of business logic is stored there with
close-relations. Additional database is not a good idea I think.

Help, please.

nasa site on django

[Vance Dubberly]

Moved http://opensource.arc.nasa.gov to django a couple of weeks ago.
 Thought ya'll might want to know that.
Also thought you might want to know the site was running on Tomcat/Mysql and
the performance difference is mind blowing.   Unfortunately the actual
server specs and benchmarks can't be released without going through a nasty
ball of red tape but let's just say django is ALOT more resource intensive
and ALOT slower.

On the plus side it is faster than a similar PHP app ( with APC ) and faster
than serving static files.

Re: How can I rename uploaded files to a random filename?

[Vincent Nijs]

If you just want to upload some files you might do something like the
following. The save function uses plain python to save the files to the
FILE_UPLOAD_DIR you defined in your setting file. You can play around with
the file names as much as you want here.

Question: Why a random name?

Vincent

class Application_files(forms.Form):
cv = forms.Field(label = 'CV *', widget = forms.FileInput(),
help_text="pdf or Word document")
paper = forms.Field(label = 'Paper *', widget = forms.FileInput(),
help_text="pdf or Word document")
  
def save(file,key,user,ext,overwrite=True):
if ext in ['pdf','doc']:
f = open('%s%s_%s.%s' %
(settings.FILE_UPLOAD_DIR,key,user,ext,),'wb')
f.write(file)
f.close()

def apply(request):
if request.POST:
for i in request.FILES.keys():
ext = request.FILES[i]['filename'][-3:].lower()
file = request.FILES[i]['content']
save(file,i,request.user,ext.lower())
   else:
form = Application_files()

return render_to_response('apply/apply.html',{'form':form,})
