Re: IPAddressField inserted as empty string although null=True

[rihad]

Incidentally this has been mentioned in the trac for 3 years by a few,
but no milestone has been set yet.
http://code.djangoproject.com/ticket/5622
Unfortunately I'm not yet knowledgeable enough in Django's inner
workings to propose a patch myself.

Re: REST XML + HTML API suggestions

[vikalp sahni]

Hi,

You might want to have a look at django-piston.

http://bitbucket.org/jespern/django-piston/wiki/Home

Its a nice project to give rest full interface to your models.

And for some specific logic also you can tweak the handlers to get desired
results.

Django 1.2 and keyless many to many on legacy databases

[Xavier Ordoquy]

Hi,

I'd like to know whether someone managed to get a many to many relationship 
with a keyless joint table.
I got a legacy database which uses that and although I can get it working on 
read mode, I have issues with writing.

I'm using this snippet (works fine with django 1.1):
http://djangosnippets.org/snippets/962/
but got no luck in patching it so that it could work with django 1.2 (and I 
need the later for permission management and multi database support).

Also I can't see how I could do it with a through table since django doesn't 
support composite keys.

Regards,
Xavier.

Re: REST XML + HTML API suggestions

[Alexandre González]

I'm using django-piston in my app, and it's incredible.

You can use XML in your RESTful API, but if you like to user another emitter
as JSON, Pickle... you can do at-the-moment! Incredible!

Making admin callables to display foreignkey relations (nested)

[N8]

No one responds to questions regarding nested inlines in the admin,
there must be a reason for that :)

But Im a django novice, and am having troubles customizing the admin
to make it intuitive for the client.  Can someone give me an example
of one of the following:

- nesting inlines of foreignkey relations (Model A - fk Model B = fk
Model C):  known not be possible in django admin by default
- or making a direct link to an admin view of Model B within Model A,
which would give a similar result ... sufficient at least
- generally how to add functions to admin actions (i need to trigger
an xml file write when the administrator saves a model instance for
example)

Any other useful links to documentations for making the admin more
customizable would be great, I havent had much success with the
documentation on this.

Cheers, thanks in advance

Re: Automatically creating fields

[tsmets]

I think, one of the question is also ...
What are these fields for ... ?
If they are derived values like : is_firstname_filled or
is_age_above_18
you should then just implement a method ... but bottom line, it looks
much simpler / efficienter / safer to implement it (as an attribute or
a method) instead of trying to generate it

Re: REST XML + HTML API suggestions

[Brian Bouterse]

I typically check the content type and have the response match the content
type of the incoming request.  I also typically have this be the only
decision that lives within views.py, and in turn calls out to code in other
modules to handle xml and/or html presentation respectively.  Also, I would
recommend using an xml processing/generating library.

Re: multiple servers one database

[Tim Arnold]

Hi Steve,
That would definitely be the easiest and simplest answer.
Unfortunately I only have power over these two machines. What I'm
trying to do is create a site that if one machine dies/hangs, the
system will continue to work on the alternate server. I just read
about the master-master mysql server setup and though that seems a
little complicated, I suppose my desires are more difficult than I
thought at first.

Any other ideas out there? Is SQLite a possibility or is master-master
the way to go?

thanks,
--Tim

ManyToManyField to Phones model for enter phones manually (not select from list)

[Anton Danilchenko]

Hi all!

Please, help me undestand, how to solve next task.

I am show for user form with two fields: user name and text field,
where user input list of phones, separated by comma. User sholud enter
one or more phones separated by comma. If user enter not valid number
- we show error message like this "Phone 12345 is not valid. Please,
enter valid phone numbers separated by comma".

I have next two models:

class Phone(models.Model):
  number = models.CharField(max_length=20)

class UserInfo(models.Model):
  name = models.CharField(max_length=70)
  phones = models.ManyToManyField(Phone)

User should enter numbers in CharField in format 0XX XXX . But, I
need save phone in database in format 0XX (only number without
spaces and other non-numbers digits).

Please, can you help me in this. I am new in Django, and I am read
more articles and not found solution. I think that I need create
custom fields for form and model.

P.S. Also, in admin section I should see CharField instead of
ManyToManyField.

Of course. You can dynamically add to self.fields in the __init__ of your form

Problems to render a tree in Json - __init__() got an unexpected keyword argument 'use_decimal'

[Rogério Carrasqueira]

Hello!

I'm new on this list and a newbie in Django. I'm recurring to this list
because I'm having a problem to implement a Json Tree using Django. I saw an
article at
http://www.elfsternberg.com/2009/05/20/fixing-an-omission-from-djangos-simplejson-iterators-generators-functors-and-closures/and
there it has a good implementation to render a tree in Json, so I
implemented my code as follow:

on utils/json.py

from django.utils import simplejson
from django.utils.simplejson.encoder import JSONEncoder

class TreeToJson:

def __init__(self, roots):
self.roots = roots

def _index(self, nodes):
def _item(node):
t = { 'id': node.id,
  'name': node.name }
  #'top': node.is_root()}
if not node.is_leaf():
t.update({'children': self._index(node.get_children())})
return t

return [_item(node) for node in nodes]

def __call__(self):
return self._index(self.roots)

def json(s,**kw):

kw.update({'cls': ExtJsonEncoder})
return simplejson.dumps(s,**kw)

At myapp/views.py

def jsonSiteList(request):

data = json(TreeToJson(Site.get_root_nodes()))
return HttpResponse(data, mimetype='text/javascript;')

But I don't know why this error is appearing when calling at browser:

*__init__() got an unexpected keyword argument 'use_decimal'*


Sorry for my so novice phase, but I'm dont know all the things on django, so
rest to me a only way: ask to the others :)

Can anyone help me with this issue?

Thanks so much!

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[nick.l...@gmail.com]

First I don't think you should be using the admin for such fine grained
control of your data formats.
BUT if you do want to do that you would want to do your validation in custom
admin forms. (created in your admin.py to do cleans on the data that's being
submitted)

Second I wouldn't do a manytomany with this, I would instead create an
inline on your userinfo model linking to phones. Then your Phone will have a
FK relationship to your UserInfo.

in models.py
class Phone(model.Models):
number = models.CharField(max_lenth=25)

class UserInfo(model.Models):
name = models.CharField(max_length=50)

in admin.py

from myproject.myapp.models import Phone, User
class PhoneInline(models.TabularInline):
   model = Phone

class UserAdmin(models.ModelAdmin):
inlines = [PhoneInline, ]

admin.site.register(User, UserAdmin)


What you get with that is the ability for a user to dynamically add as many
phone numbers to a user as they want. Also you get the charfield (instead of
the select box, which is what you get from the M2M field)

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[nick.l...@gmail.com]

Let me rephrase my first statement...You can use the admin for fine grained
control of your data formats and characters. But don't use the Database to
control the characters and formats. Use the database as a storage and make
sure that anything you store gets cleaned.

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[Anton Danilchenko]

In my case, I have Users with equal phone numbers. And I need only
ManyToMany relationship.

I need create custom field for get information from CharFiels,
validate this data, clean and save to datastore in separate model. If
this phone already exists - we get ID of this phone. And, if this is a
new phone number - we insert this phone to separate model and get new
ID.

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[nick.l...@gmail.com]

Maybe I don't understand your problem.

It sounds to me like your trying to make this way more difficult than it
needs to be.

Also it sounds to me like your trying to assign the same phone number to
multiple people. (which is fine) But doesn't make a lot of sense to me in a
practical application.

Django 1.2.1. admin WYSIWYG editor

[Sithembewena Lloyd Dube]

Hi,

Has anybody intergrated a WYSIWYG editor in the admin of a Django 1.2.1.
site? I have tried django-wysiwyg and TinyMCE to no avail. I need something
with concise, up-to-date documentation.

If anybody has done this, please recommend and also point to the docs?

Thanks.

I just downloaded newest tinyMCE and placed it in 'js' directory, then i  
made proper cfg


in modelAdmin:


class Media:
js = ('js/tiny_mce/tiny_mce.js', 'js/tiny_mce/tiny_mce_config.js',)

and the config in tiny_mce_config.js file:


tinyMCE.init({
mode : "textareas",
width : "800",
height : "500",
theme : "advanced",
language : 'pl',
content_css : "../../css/style.css",
theme_advanced_toolbar_location : "top",
plugins : 'preview, searchreplace, paste, table, insertdatetime, media',
theme_advanced_buttons1 :  
'preview,undo,redo,visualaid,|,cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,link,unlink,anchor,image,cleanup,help,code',
theme_advanced_buttons2 :  
'bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,|,styleselect,formatselect,fontselect,fontsizeselect',
theme_advanced_buttons3 :  
'forecolor,backcolor,|,sub,sup,|,charmap,insertdate,inserttime,media,|,tablecontrols'

});

and it works fine in admin panel with textareas

Synching samba users to django users?

[MrMuffin]

Hi,

I need to sync samba users ( and generally manage samba users, samba
shares and start/restart the samba service ) from within django. I've
googled for hours and emailed some people on the samba site, but
haven`t gotten any answers.

I want to create a reusable app that can handle samba management and
especially manage samba user accounts, synching samba users and their
passwords to the user profiles defined in django.

Any hint or clue would be highly appreciated. My project will run on
ubuntu, I`ll use any library available to achieve this goal as long as
it has python bindings. The project will be released as free software.

Thanks! :-)

Re: Synching samba users to django users?

Did you thought to use a third party solution creating a LDAP server and
syncs the Samba and Django system with the LDAP?

Re: Synching samba users to django users?

[MrMuffin]

Yes, that`s one option I`ve looked at, but I also need to manage
shares and restart the samba service when the config has been updated
so it would be better to have a library that managed samba directly.
But if I cannot find any other alternative, LDAP might be the best
solution for my problem.

Thanks for your input :-)

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[Anton Danilchenko]

I describe my task more reallistical.

This is application for rent an apartment. User can create new message
with information about apartment, and also add one or more contact
phone numbers. One user, without registration, can create more that
one message on the site. For one message can add one phone number, for
other message add two phones.

I need to save only one copy of phone number in database in format
. For each phone I can set if this phone in black list or not
(model Phone have property "blocked" by default setted to False).

I want to save phone numbers in model Phone, and messages in model
Message. But, people can see input text field (CharField) where enter
one or more phone numbers separated by comma.

class Phone(models.Model):
  number = models.CharField(max_length=20)
  blocked = models.BooleanField(default=False)

class Message(models.Model):
  # ... information about count of rooms, floor, cost, etc ...
  phones = models.ManyToManyField(Phone)


Nick, thank you for you help. You are really very good people!

filepath (system file system path) field

[pixelcowboy]

Hi, I have seen this asked before here (without answers), but I wanted
to know how to go on about creating a field that stores filepath names
from the client filesystem, so I wanted to check if someone could
recommend the best apporach: Creating a custom field perhaps? Or
perhaps extending the filefield? Or maybe just use a charfiled and do
it all in validation? What do you guys think?

Header being removed or overwritten

[TheIvIaxx]

Hello, I have recently switched over to nginx as my front end server.
All is well.  However i have a view that sets the Cache-Control header
to no-cache.  But when going to this view, it looks like nginx is
either overwriting the header value or removing/ignoring it all
together.

I'm not 100% i have the server set up correctly, but it is working:

apache/mod_wsgi running on port 8080

nginx:

location ~* {
proxy_pass http://X:8080;
break;
}

Any ideas on this?  Is my setup incorrect?

Re: Synching samba users to django users?

[Doug]

You could create a secondary python script running as root that polls
a queue or config file generated by your django app.  Have that script
perform the requested actions by running the same executables as a sub
process and checking the exit codes.  If you need immediate responses,
it could run like a daemon/service sleeping between poll intervals...
or via a cron job if you can deal with the delayed actions.

select_template but return only template name?

[ringemup]

I've set up a theming system that relies on using select_template to
find the correct template for each view, searching first the skin's
template directory, then the theme's template directory, then the
master template directory.  (A "skin" in this case being mostly a
stylesheet that applies a color scheme to a "theme", which determines
the markup.)

However, I'm tripping up badly on built-in views such as the
contrib.auth views, many of which can take a template name as an
argument, but not an actual template.  Being able to do the equivalent
of select_template and returning only the template name rather than
the actual template object would be a big help.

Any tips?

Thanks!

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[nick.l...@gmail.com]

PersonallyI don't like the idea of adding multiple phone numbers as
comma separated values.  What happens when a user's trying to add more phone
numbers than your charField's max_length?

So let me see if I understand what's going on here...

You have a problem where exists apartments for rent. People who want to rent
these apartments will send messages to the owner of said apartment (through
your website). This message will have associated to it, a User and Multiple
Phone Numbers.

This message is then checked to see if the phone numbers associated to it
have been black listed...
And then finally deliver the message?

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[Anton Danilchenko]

Message - this is a rental proposition (rooms, floor, cost, area,
country, cirty and contact phones).

Visitors can create new messages (message - this is a rent
proposition) and enter list of own phones (one or more phones). My
application store this phones not in char field, but save each phone
number to separate Phone morel - one phone in one model). If phone
already exists - message attached to this phone. If phone not exists -
we create new phone and attach message to this phone number.

In future, I tell to people - and see that this people not a good
man :-). I go to my application and mark this phone number to black
list. All future messages from this people to be marked as bad
messages.

Now I need to create own Form field called MultiPhoneField based on
CharField widget, but implenet logic of ManyToManyField. I need show
for user CharField where user enter comma separated phone numbers. I
check this numbers and if all numbers correct - store this numbers in
database in Phone model (each phone in separate record) and associate
message with list of this phones.

Can you please help me in this. I not understand how to create my own
Field based on ManyToManyField.

Thanks!

Localization time formatting

[tsuraan]

What do you have to do to get the localized datetime formats to work
in Django?  I started a new project, set LANGUAGE_CODE to 'en-GB',
enabled LocaleMiddleware (doesn't matter for this test though), and
ran "django manage.py shell".  In the shell, I had the following
session:

>>> from django.conf import settings
>>> settings.LANGUAGE_CODE
'en-GB'
>>> settings.DATE_FORMAT
'N j, Y'
>>> settings.SHORT_DATE_FORMAT
'm/d/Y'

So, obviously setting the LANGUAGE_CODE doesn't seem to affect the
locale that django uses when getting the date/time format strings.
What variable does do this?  I can see that in
django/conf/locale/en_GB/formats.py there are formats for date and
time, but I can't figure out what function I have to call to activate
them instead of the american formats.

Why Django Apps Suck

[klaasvanschel...@gmail.com]

Ok here it goes: I don't have a proper platform for my observations /
rants so I figured I'd try my luck here. Django has been my favorite
framework for developing web applications for about a year and a half,
so it comes from a position of love when I say that the Django app
really sucks as a level of abstraction. And I'm really looking for a
way out so any suggestions are much appreciated. A tl;dr is provided
below.

Others have complained before me. Two particular ones worth mentioning
are:
http://www.scribd.com/doc/37113340/Why-Django-Sucks-and-How-we-Can-Fix-it
which claims that "Apps which provide models are inflexible" and
http://www.mutualinformation.org/2010/03/why-i-switched-to-pylons-after-using-django-for-six-months/
Both claim that the Django app provides the wrong level of
abstraction, neither goes in too much detail exactly why that is the
case. That's the question I'll attempt to answer.

Before we can answer the question we must first set some reasonable
expectations for an "app". I'd say an app is a small package of
closely related features as they are presented to the user (in the
context of a web project) that can be easily modified/extended for any
given project.

Examples of apps (in my own particular context):
* Dealing with customer information (a mini CRM). Adding, editing,
useful overviews.
* A small news app (Add, edit, overviews)
* Our own particular UserProfile app (editing, viewing others,
birthday calendars etc.)
* A small budgetting tool (creating budgets, see how much money has
been used)
* Logging time lines (for worked hours), searching them.

I choose this definition for "app" because it is a very useful one in
the context of web projects. At least in my context it works like
this: we have a lot of customers with similar intranets and extranets.
Each one of them might want a particular subset of the various apps we
have "on the shelf".

By the way: there's other things that can already be reused quite
well. Anything pure python for example. Or extensions to Django (extra
fields, extra context managers, middleware etc etc.) This is not my
concern, mainly because it already works well.

One thing that deserves extra stress is that apss should be easily
extendable. Exactly the fact that every customer want something that
is slightly different from the next is how we're able to provide
value. (This is also the reason I like Django in the first place:
making stuff "your own way" is very easy). So: if no one want exactly
the same, extensibility is a major prerequisite for reusability.

What are some typical things we want to do when extending (modifying)
an app for the context of a particular project?
* Deal with authorization in the context of the particular django
project
* Styling for the project
* Turn a subset of the functionality on or off for a given project (no
docs, no 'advanced features')
* Add one or more fields to one or more models and possibly related
edit pages, view pages forms etc

Given this control flow let's try to do some of the typical
modifications mentioned above:
Authorization:
Django has a beautiful mechanism for authorization, which is using
decorators (@may_do_a_b_or_c) directly in the views.py.
Tempting, but will not be modifyable in any way once you lift the app.
(because the decorator will become tied to the view function). Other
mechanisms are not presented (in a standardized way). If anyone has
ideas about this I'd love to discuss them.

Styling:
This actually works well, by providing sufficient amount of hooks in
the templates and extending.

Turning functionality on and off:
This could be made to work by working with a 'url_parts.py' in the
reusable app, that provides different url_patterns for the various
subsets. So one for the CRUD, one for the docs, one for the simple
features and one for the advanced features. Our project's urls.py
would then simply include the right subset from this url_parts.py. I'm
not sure it's very pretty though.

Extending models
This is the big one, for two reasons.
1. You almost always want to do this (for any change to the app that
is reflected in the underlying data)
2. It's pretty much impossible.

Why is it impossible?
Firstly, /app/models.py is always discovered, so unless we make all
Models abstract, or we do not include "app" in settings.py, models are
created for syncdb and any related commands.

Secondly, let's take a look at Django's control flow:
* urls.py matches and calls,
* possibly via a decorator
* a view in views.py, that may use any number of
  * models,
  * forms and
  * templates
The "official" way to modify a reusable app for your particular app is
by making it available as a kwarg with proper default in the view, and
then customizing it from urls.py.
However, if you simply want to add one field to a much used object,
this solution implies passing around the object class (factory)
through your whole app. That's not very elegant.
The same goes for any other changes at a lower level. Say I want

Wow! I guess your definition of an app  and expectation of re-usuability
from an app written by someone else
is fairly high!

We have built serveral news sites based on Django, and a lot of code gets
rewritten everytime, because customer requirements are very different. We
reuse 90% of code in every project, but 10% gets rewritten or gets writtenf
fresh.

I know there's a number of apps out there including ones written by people
like me, which are grossly unusable. I guess that's primarily because its
written by developers for a specific work, and when they threw it back into
the wild, they did not pay enought attention tomake it really re-usuable.
However there are quite a few exceptions,

I completely agree with your views that with the way you write code with {%
url in templates, and decorators, reusing the code is a pain. I had to scrap
a project based on Pinax for the same reason, and then rewrite a mini scoial
framework, because pinax is not customizable beyond a point.

However my personal experience is that it's true for most platforms. There
are always trade-offs and trade-ins when you use a platform.

Customizing and Suppressing "Select a valid choice. That choice is not one of ..." error?

[ydjango]

How to customizing and suppressing "Select a valid choice. That choice
is not one of ..."  error?

I have two requirements:

1) for some select drop downs, I want to customize the message
 "Select a valid choice. That choice is not one of ..."
to

 "Select a valid choice for field ABC. 12 choice is not one of ..."

is there a way I can do it in form. Like I can specify my own message
for 'Required'

2) Some cases, I want to add the user input as a new data to the db.
In that case I do not this validation error to be raised. How do I
suppress it .

Shawn: thanks

unique.

Actually, a big part of the problem is reusing my own apps. Mostly
since all of them provide models, and every use case either needs
changes to those.

That's interesting.
Do you adapt models across your apps?
Do you deal with (some kind of advanced) authorization that differs
over projects?
I'd like to know how.

Yeah I looked at Pinax too (because it is presented as a "reusable
app") but I was a bit disappointed. (not so much in the app, as in how
it is an example of reusability).

Problem is "{% url %}" is presented as a Good Thing (DRY) while it
makes reuse in some ways harder
What's your alternative, i.e. how do you provide links that are
project independent?

ChoiceField -suppressing "Select a valid choice. That choice is not one of ..." error?

[ydjango]

How to suppress invalid_choice validation error for choicefield
-"Select a valid choice. That choice

I am using a client side combo box where user can either select from
the choices or add a new value. For new value Django - ChoiceField

Re: Why Django Apps Suck

[Mike Dewhirst]

Also at pycon-au http://glamkit.org/ where the talk focused on 
reusability of apps.

Ok here it goes: I don't have a proper platform for my observations /
rants so I figured I'd try my luck here. Django has been my favorite
framework for developing web applications for about a year and a half,
so it comes from a position of love when I say that the Django app
really sucks as a level of abstraction. And I'm really looking for a
way out so any suggestions are much appreciated. A tl;dr is provided
below.

Others have complained before me. Two particular ones worth mentioning
are:
http://www.scribd.com/doc/37113340/Why-Django-Sucks-and-How-we-Can-Fix-it
which claims that "Apps which provide models are inflexible" and
http://www.mutualinformation.org/2010/03/why-i-switched-to-pylons-after-using-django-for-six-months/
Both claim that the Django app provides the wrong level of
abstraction, neither goes in too much detail exactly why that is the
case. That's the question I'll attempt to answer.

Before we can answer the question we must first set some reasonable
expectations for an "app". I'd say an app is a small package of
closely related features as they are presented to the user (in the
context of a web project) that can be easily modified/extended for any
given project.

Examples of apps (in my own particular context):
* Dealing with customer information (a mini CRM). Adding, editing,
useful overviews.
* A small news app (Add, edit, overviews)
* Our own particular UserProfile app (editing, viewing others,
birthday calendars etc.)
* A small budgetting tool (creating budgets, see how much money has
been used)
* Logging time lines (for worked hours), searching them.

I choose this definition for "app" because it is a very useful one in
the context of web projects. At least in my context it works like
this: we have a lot of customers with similar intranets and extranets.
Each one of them might want a particular subset of the various apps we
have "on the shelf".

By the way: there's other things that can already be reused quite
well. Anything pure python for example. Or extensions to Django (extra
fields, extra context managers, middleware etc etc.) This is not my
concern, mainly because it already works well.

One thing that deserves extra stress is that apss should be easily
extendable. Exactly the fact that every customer want something that
is slightly different from the next is how we're able to provide
value. (This is also the reason I like Django in the first place:
making stuff "your own way" is very easy). So: if no one want exactly
the same, extensibility is a major prerequisite for reusability.

What are some typical things we want to do when extending (modifying)
an app for the context of a particular project?
* Deal with authorization in the context of the particular django
project
* Styling for the project
* Turn a subset of the functionality on or off for a given project (no
docs, no 'advanced features')
* Add one or more fields to one or more models and possibly related
edit pages, view pages forms etc

Given this control flow let's try to do some of the typical
modifications mentioned above:
Authorization:
Django has a beautiful mechanism for authorization, which is using
decorators (@may_do_a_b_or_c) directly in the views.py.
Tempting, but will not be modifyable in any way once you lift the app.
(because the decorator will become tied to the view function). Other
mechanisms are not presented (in a standardized way). If anyone has
ideas about this I'd love to discuss them.

Styling:
This actually works well, by providing sufficient amount of hooks in
the templates and extending.

Turning functionality on and off:
This could be made to work by working with a 'url_parts.py' in the
reusable app, that provides different url_patterns for the various
subsets. So one for the CRUD, one for the docs, one for the simple
features and one for the advanced features. Our project's urls.py
would then simply include the right subset from this url_parts.py. I'm
not sure it's very pretty though.

Extending models
This is the big one, for two reasons.
1. You almost always want to do this (for any change to the app that
is reflected in the underlying data)
2. It's pretty much impossible.

Why is it impossible?
Firstly, /app/models.py is always discovered, so unless we make all
Models abstract, or we do not include "app" in settings.py, models are
created for syncdb and any related commands.

Secondly, let's take a look at Django's control flow:
* urls.py matches and calls,
* possibly via a decorator
* a view in views.py, that may use any number of
   * models,
   * forms and
   * templates
The "official" way to modify a reusable app for your particular app is
by making it available as a kwarg with proper default in the view, and
then customizing it from urls.py.
However, if you simply want to add one field to a much used object,
this solution implies passing

We don't do anything that's extra-ordinary. Tried it and it failed. While I
have not quite experimented in depth with Pylons, the problem what you are
describing about reusability exists in some way or other with every
platform. We've been through almost all major frameworks from Java based
ones to CakePHP to Rails.

I'm sorry to disappoint, but all I do is move code between projects and then
customize models, views and urls according to the needs.
Even an app which is pretty well written like django-registration, I had to
customize it number of times to suite specific needs of some of my
customers, that my versions are impossible to reuse.

Problem with ForeignKey()

[Yo-Yo Ma]

I have a model with:

parent = ForeignKey('self', blank=True, null=True)

In that model I've overridden clean() to contain:

if self.parent:
# Do some stuff

It raises an attribute error saying that parent.pk doesn't exist. How
can I get around this. Note that my foreign key is recursive.
