newforms for idiots and designers?

[Austin Govella]

I'm *almost* getting forms to work, but not quite.

Can anyone recommend a newforms tutorial written for designers?
Something akin to Zoolander's School for Kids Can't Program Good.



(And I *have* been reading. What's odd is that I used similar
structures when I was coding php and coldfusion, but I can't get it to
work here.)

Re: foreign key on database not created with models referencing from other application

[james_027]

Hi,

I dont know what you mean by what_I_have_done?

I just follow the django tutorial. the one with poll and choice model.
I did every step. and that's my result.

However I have discover something 

this setting
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',

)

vs this setting

INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.admin',

)

will produce a different result ... the first setting will have
foreign key on the django_admin_log table while the 2nd table dont
have the foreign key. I have do this multiple time, changing the
settings between the first and the second and the result is constant.

do we have ordering in creating models?

thanks
james

When I run your example, the foreign key IS created. You are not the
first person to create a foreign key reference across applications,
and we haven't had any other complaints to date, so I am almost 100%
confident that the problem isn't with Django.

Deleting an item out of my dictionary?

[Greg]

Hello,
I have the following views

def showcart(request, style_id, choice_id):
s = Style.objects.get(id=style_id)
#assert False,s
c = Choice.objects.get(id=choice_id)
#x = c.size, " ", c.price
cart = request.session.get('cart', [])
cart.append({'style': s, 'choice': c})
request.session['cart'] = cart
pr = 0
for a in cart:
pr = pr + a['choice'].price.name
return render_to_response('show_test.html', {'mychoice': cart, 'p':
pr})


def deletecart(request):
del request.session['cart'][0]
# x = request.session['cart'][0]
# assert False,x
return render_to_response('themainpage.html', {})



Shouldn't the line in the 'deletecart' view delete the first item in
my dictionary?  Whenever I access the 'deletecart' view I don't get an
error, but it doesn't delete the dictionary[0] element.

Whenever I do a 'assert False, x' I get the following error:

{'style': , 'choice': ,
)>}

so why isn't the above line getting deleted from my dictionary when
using 'del request.session['cart'][0]'?

Thanks for any help

I didn't say that the relation aren't working, I just wondering why

I would suggest setting up some purpose based widgets - a DateWidget
and a TimeWidget - that define their attributes. Then, compose your
SplitDateTimeWidget out of the two custom widgets, rather than using
two standard TextInputs and trying to pass attributes down to them.

Not even close.

Perhaps I'm not being clear. I have tried your example. It works for
me. The fact that many thousands of other people use Django and
haven't experienced this problem leads me to suspect that the problem
lies with you, not Django.

However, you are obviously having a problem. What I need you to do is

Starting with no database in existence, and no django project at all,
how did you get into the situation?

I also need to know HOW DO YOU KNOW THAT THE RELATION DOESN'T EXIST.

You were on the right track with __unicode__().

__unicode__ is the instructions to Python as to how to produce a
human-readable representation of this object (in unicode). I'm
guessing what you tried was:

def __unicode__(self):
   return self.year

which failed. This failed because what you are returning is an
integer, not a unicode string, so when the return value is combined
with other strings it raises an error. However, if you make a slight
change to convert the year into a string before it is returned:

def __unicode__(self):
   return unicode(self.year)

Everything should work nicely. You can even get creative, and add in
other bits of text:

def __unicode__(self):
   return unicode(self.year) + u" Season"

So that what gets display isn't just a year, but "1999 Season".

Hope this helps.

Russ Magee %-)

Re: foreign key on database not created with models referencing from other application

[james_027]

Hi,

The table was created fine with only a small problem and it's the
foreign key. I have my application listed on settings.py, code my
model on models.py, then perform manage.py syncdb my_app as I am aware
that if the table exist it wont recreate it. I did a number of times
of deleting my tables and do manage.py syncdb my_app.

As I stated the django_admin_log table should also have foreign key
which also doesn't have it since it has a relation to auth_user table.

I am doing this in winxp , mysql 5 , python 2.5 , latest mysql driver
for python. Hope I've provided enough info.

Thanks
james

Are you sure you're not looking for the 'params' argument to extra?
This will use the cursors string substitution, which should to the
escaping/quoting you are looking for (IIRC).

Ultimately it will depend on your caching mechanism, but in theory,
any page that has been retrieved with GET should be cacheable, without
consequence, parameters and all. GET is intended to be a resource
retrieval, and if you're just retrieving, you're not modifying the
server, so it should be cachable.

Remember, the object isn't created until you POST the data, and it's
the POST that can't be cached. Caching the GET ..model3/add/?model1=2
page just means that the unsubmitted form with a hinted value for
model1 has been cached, ready for the next person that wants to add an
instance of model3 with the same hinted value.

I think you need to be a little bit more clear on what you have done -
and I mean precise instructions. _EXACTLY_ what steps have you taken,
and how have you come to the conclusion that the foreign key hasn't
been created?

Creating tables is an operation that gets done every day by many
people, without difficulty. I have tried the models file you provide,
in various orders of creation, and have had no problems. Without
knowing exactly what you have done, it is impossible to know what has
gone wrong.

I ran into that problem a few weeks ago.  I believe I posted something

I have a class in my Models that contains one field which happens to be an integer type

[jeffself]

In my model for my application, I've created a class called Season.
There is only one field in this class and that is called year and its
of type integer.  In another class called Game, I have a field called
season which is a ForeignKey to Season.  When I bring up the add Game
form in the Admin, my Season select box only displays 'Season Object'
instead of the value of the season.  How do I get the season to
display in the select box of my season field on the Game form?
Normally this would be fixed by using def __unicode__(self) but since
its not a CharField, I can't use that.  I tried def __integer__(self)
but that didn't make a difference.

I'm pretty new to Django and I'm loving it so far.

foreign key on database not created with models referencing from other application

[james_027]

I am very new to django, I am creating a model with a field of
models.ForeignKey(User) #django.contrib.auth.models import User. When
I look at the database, my table has no foreign key define. Another
example is the django.contrib.admin.models.LogEntry model it has user
= models.ForeignKey(User) which is also from
django.contrib.auth.models.user.

When the relationship is within the same namespace (am I using the
right term, pls correct me) the manage.py syncdb create the tables
without a problem if all the tables are create on the same time, but
if the tables weren't created the same time it also fail to create the
foreign keys.

Where should I look to correct this problem.

from django.db import models

from django.contrib.auth.models import User



# Create your models here.

DEPARTMENTS = (
 ('HRD', 'HRD'),
 ('ACT', 'Accounting'),
 ('PUR', 'Purchasing'),
 ('LOG', 'Logistics'),
 ('PRO', 'Production'),
 ('MKG', 'Marketing'),
 ('EXP', 'Export'),
 ('ITD', 'IT'),
)



LEVELS = (
 ('SM', 'Senior Manager'),
 ('MR', 'Manager'),
 ('SP', 'Supervisor'),
 ('ST', 'Staff'),
)

class Profile(models.Model):
 """KSK Employee accounts to use this application""
 user = models.ForeignKey(User)
 department = models.CharField(maxlength=3, choices=DEPARTMENTS)
 level = models.CharField(maxlength=3, choices=LEVELS)

Most shared hosting providers provide support for postgresql also (I
can quote the case of webfaction here). Postgresql is an ACID
compliant database server and has a lot of features that databases
like MySQL do not support like check constraints. If you plan to have
a moderate traffic website (with less than 1000 hits per day) I would
recommend SQLite (which too is ACID compliant). The primary reason
most Django developers prefer Postgresql is that it scales very well.
The only reason to go for MySQL should be if you have no alternative.
MySQL may be very easy to setup and administer but it isn't ACID
compliant.

Newforms - attributes for splitdatetimewidget

[jeffhg58]

Hi,

I am just digging into the newforms functionality. I am looking at the
splitdatetimewidget.
I am trying to having a different attributes for the first field and
the second field, and would like to know how to go about doing it.

Here is the snippet of my code

calendar_widget =
forms.widgets.SplitDateTimeWidget(attrs={'class':"vDateField
required", 'size':10})

AddEventFormClass.base_fields['event_date'].widget = calendar_widget

I am trying to use the class of vTimeField for the second field.

Thanks,
Jeff

Re: Which database, and why?

[Joe Bloggs]

PostgreSQL scales better with more users

http://tweakers.net/reviews/649/7

MySQL accepts the date 31st February 2007 and has several other lax views of
rounding data or squeezing it in when it should reject it.

http://safari.oreilly.com/0596002114/msql2-CHP-16-SECT-3

MySQL only supports transactions with the InnoDB backend which has been
bought by Oracle.

http://www.innodb.com/

You can do a hot backup  ( backup when the database is open ) of PostgreSQL
without buying software - you have to buy the InnoDB hot backup software.

The best point for MySQL is that the query "select count(*) from table" is
much quicker than PostgreSQL.

You have to remember to auto vaccuum a postgresql database to get rid of old
data that is no longer required.

MySQL is dual licensed both open source and commercial. I still haven't got
my head around this one - if you distribute a product that includes MySQL
for money then you need to buy a license. PostgreSQL is the BSD license so
is totally free to use as you wish.

In general if you don't already have expertise in MySQL then you should
always choose PostgreSQL - my opinion for what it's worth :-)

Re: Some questions on Django's authentication system

[Nathan Ostgard]

Regarding the first question, you can do this by creating a middleware
class which checks for authenticated users by default. You could also
created a decorator to tag view functions as public. For example...

in file yourproject/yourapp/middleware.py:

  from django.conf import settings
  from django.contrib.auth import REDIRECT_FIELD_NAME
  from django.http import HttpResponseRedirect
  from urllib import quote

  def allow_anonymous(view_func):
view_func.allow_anonymous = True
return view_func

  class RequireLogin:
def process_view(self, request, view_func, view_args,
view_kwargs):
  if not getattr(view_func, 'allow_anonymous', False) and not
request.user.is_authenticated():
return HttpResponseRedirect('%s?%s=%s' % (settings.LOGIN_URL,
REDIRECT_FIELD_NAME, quote(request.get_full_path(

Then add 'yourproject.yourapp.middleware.RequireLogin' to
MIDDLEWARE_CLASSES in settings.py.

Now you can use it in your view:

  from yourproject.yourapp.middleware import allow_anonymous

  def some_private_view(request):
# won't be accessible unless user is logged in
return HttpResponse('Hello, user!')

  @allow_anonymous
  def some_public_view(request):
return HttpResponse('Hello, world!')

Re: removal of Django

[Julio Nobrega]

  Hi,

  You probably went to a website and saw a 404 error message saying
that Django could not find the page. The thing is that what you're
seeing is the message sent by Django installed on the server, not on
your computer. There's no Django installed on your PC.

Re: Accessing the backend's string-quoting functionality?

[Tim Chase]

This seems to be (browsing the code) the table/field-name
escaping mechanism, not the "escaping/quoting dangerous
characters in a string so it can be put in a query" function.
The backend.quote_name function wraps a string in the back-end's
quote-chars (back-ticks in one, double-quotes in another).  The
function of interest usually doubles single-quotes, as well as
handling oddball control/unicode characters.  A little digging
shows this to be mysqldb.escape_string(), sqlite.escape, and the
psycopg.QuotedString object.


I didn't see them mentioned in any of the code in the backends/
directory.  Would a patch be considered?

Some questions on Django's authentication system

[eXt]

Hi all!

   I build an application which will use Django's authentication
system. This is my first Django application that uses auth system, so
sorry if the questions below are trivial.

   1. Do I have to decorate all views with login_required if I want to
keep them secured? Isn't there any inversed method which will secure
all views by default, and I will only enable some of them to public?

   2. My use case is that I need to save ip addresses of users who are
logging into my application. First thing is how to extend user model,
but I think that I found the proper solution in Django Book (user
profile). Second thing is what to do to catch 'logging in' event to be
able to read an ip from request and save it (even if the
authentication isn't successful)? Is it possible to set an event on
existing login method (django.contrib.auth.views.login), or should I
do something different, for example write my own login view?

Hmm.. thats all :)

Thanks in advance.

Re: Which database, and why?

[[EMAIL PROTECTED]]

I have had some really annoying performance problems with sqlite
concerning multiple joins partially over views.

The query optimizer did not do his job there and switching two joins
brought a performance boost of several orders of magnitude. This is
actually a thing that is hard to do with djangos ORM, since you are
not really writing SQL.

Thus I would recommend a full scale dbms once you have a more complex
ER model.

Accessing the backend's string-quoting functionality?

[Tim Chase]

When working with an extra() call, I need to pass massaged
parameters to a subselect using the where=[""].  However, I'd
like to be able to access the back-end's quoting abilities.  As a
stop-gap, I currently am simply doing a replace of a single-quote
with two single-quotes.  However, I've heard there's that should
be escaped depending on the back-end.

Is there a way to access the back-end's string-quoting mechanism?

Re: Which database, and why?

[Tim Chase]

> I know that PostgreSQL is recommended, but why? Are the django
> developers assuming a high-traffic, database intensive site. Are the
> django developers assuming that you will not be using shared hosting?

Any of the big three (PostgreSQL, MySQL, and sqlite) are quite
well supported in Django.  In my (highly subjective) experience,
the following applies:

PostgreSQL:
 -scaling: +2
 -able to be run on a 2nd server: yes
 -easy administration: 0
 -easy configuration/installation: -1
 -ANSI SQL compliance: +2

MySQL:
 -scaling: +1
 -able to be run on a 2nd server: yes
 -easy administration: +1
 -easy configuration/installation: 0
 -ANSI SQL compliance: +1 (formerly "-1.5")

sqlite:
 -scaling: -1
 -able to be run on a 2nd server: not really
 -easy administration: +1
 -easy configuration/installation: +1.5
 -ANSI SQL compliance: +1.5


To me, that means, if you've got a site that doesn't need to
scale because it should experience minimal traffic, go with
sqlite.  Especially for local development.

If you're entertaining a site that needs to scale, go with
PostgreSQL unless you have a reason to prefer MySQL
(pre-existence on the hosting service, or ease of getting it
running).

MySQL's ANSI compliance has improved considerably since the days
I cursed its lack of things like views and subselects, but there
are still a few common ANSI features missing, or you have to
specify features on the table creation (though Django does
provide initial-sql hooks on a per-backend basis).  I think it's
this historical baggage of non-ANSI-compliance for MySQL that
dings it to a lower status than PostgreSQL.  As the newer, more
compliant versions of MySQL begin to be more available on hosting
services, this gap will close.

My $0.02

We only have 2 developers and because of Django, that's all we need.
We hired the 2nd awhile ago and he had some Python experience and
picked up Django very quickly.  The good documentation helped a lot in
that regard.  That in itself is another point -- a home grown CMS in
PHP with no docs would have taken much longer to figure out and get up
to speed with.

The MVC model, I think, would also help.  As the new employees are
learning they can work in something less technical like templates.  As
they learn, they can then do views.  And the senior devs can do things
like model design, middleware, new features, whatever.

Python and Django wouldn't be my concern when hiring new employees
since they are easy to learn.  It's all the other stuff that comes
with web development that together is harder to find (eg: valid
(x)HTML, CSS, Javascript, database, source control, unix/linux, HTTP,
etc.)

Re: Blog engine

[Rob Hudson]

A lot of the same arguments against making a standard blog project
could probably be applied to Rails, but here's a blog app in Rails...
http://simplelog.net/

I think an open-source Django blog project would be good because
1) It would be Usable to many (as evidenced by this thread and others
before)
2) Useful to many as a reference and resource

#2 is particularly interesting to me because I've written a simple
blog in Django and there are some non-obvious things that having a
reference implementation to look at would be nice.  Things like:

* Feeds (Atom, RSS, both)
* Comments (with spam filters)
* Open-ID enabled comments?
* Grouping blogs and links and whatever other objects by date using
generic relations (possibly?)
* Previewing links that aren't "published" yet, possibly using the
ADMINS option, while returning a 404 for anyone else?
* Writing a script executed by cron to pull content from other sources
and save them to your models.  (I did this for Magnolia recently.)
* etc.

If anyone wants to start one I'd be interesting in joining in and
playing.

Re: Newbie Question: Static Media With Development Server - Not The Same Old Question

[cjl]

Nathan:

Thank you for your reply.

Your solution seems practical, but I found another solution. In
'settings.py' I have:

MEDIA_ROOT = './static/'
MEDIA_URL = 'static/'

and in 'urls.py' I have:

(r'^static/(?P.*)$', 'django.views.static.serve',
{'document_root': 'static'}),

Then in the templates I can have:

http://localhost:8000/static/picture.png;>

Which seems to work for me, and avoids any hardcoded paths for my
tutorial.

Also, note that with your solution calling your media url 'media' will
clash with the default name for admin media, although I'm sure that
you knew that, and that you were only providing an example.

Thanks again,

Re: Can Django call cscript.exe to run vbscripts

[Dennis Allison]

actually, look at module subprocess rather than os as the subprocess 
module contains the current best practice solution.   (Check the Python 
3000 docs to see what will be going away and avoid using them.  :-) )

BUT, the vbscript GUI will not be available throught the web, at least not
easily.

Which database, and why?

[walterbyrd]

I know that PostgreSQL is recommended, but why? Are the django
developers assuming a high-traffic, database intensive site. Are the
django developers assuming that you will not be using shared hosting?

I seems to me, that if you are using shared hosting, and if your
database needs are modest, Sqlite3 might be the best choice.
Especially when Python 2.5 becomes more standard on shared hosting.

For one thing, with sqlite, you don't have to share a database server
with others. Judging from the way Drupal runs on dot5hosting, or
dreamhost, this might make a real difference. Also sqlite is almost
trivial to setup and administrate.

Has anybody had any particular difficulties with MySQL?

What does it mean to restart Apache?

[walterbyrd]

As I understand it, if you run django under mod_python, then you have
to restart Apache every time you make a change to the django code.

Does restarting apache mean that apache is completely shut down? So if
I'm on shared hosting, then anybody else using the apache server, will
have to wait until apache restarts?

I can't imagine that any shared-host service would allow that.
Although, I think some hosts, like WebFaction, give everybody their
own apache server.

Can anybody clear this up for me?

Re: Mapping models to CRUD urls?

[John Matthew]

Russ,

This is GREAT stuff, thank you so much.

Since I'm so new to this web stuff, and django is really the only thing I've
ever used for web programming, I hadn't gotten into the GET dictionary (or
parameters as I call them).

Given that, I assume that the cache will look at the http://.../model3/add/
and cache that?  meaning it doesn't add the parameters to the cache lookup?

This actually makes my setup a little simpler, and i'll start on it soon.

Thanks again for all your help.

John

Nope - haven't tried it. I'm still in the early stages of design.

One thing I realized last night, is that it would be better to append
a key to a subdomains table than the actual subdomain. That would make
changes a lot easier.

form_for_model with custom modifications and save()

[ilDave]

Hello!
I'm using form_for_model to create a form for a particulary complex
model.
I don't want to show a particular field of the model in the form, so I
did this:

PreventivoForm =  form_for_model(Preventivo)  #Preventivo is the name
of the model
del PreventivoForm.base_fields['codice'] # codice is the field I don't
want to show, because it's value must
be
   #
calculated from other data

and the form is nicely displayed like I want.

But when I try to save the data in the form in a new model, I get an
exception, because the 'codice' field is a required field in the
model:

f = PreventivoForm(request.POST)
if f.is_valid():
   p = f.save()

Is there a way to add the field I need before saving or have I to
handle the saving of the object manually?

Re: How to loop through a Dict to add values?

Ok...on to a new problem.  I'm able to add stuff to my session and
also delete the entire sesssion.  However, I'm not sure how to delete
a particular entry into my session variable.  This is how i add stuff
to my session

cart = request.session.get('cart', [])
cart.append({'style': s, 'choice': c})

What method do I use on request.session to delete only one "row" in my

The Django Book isn't my bailiwick - that's Adrian and Jacob's
project. While I'm sure it will be a wonderful tutorial and reference
when it is published, it won't ever replace the official
documentation.

The 'official' newforms documentation
(http://djangoproject.com/documentation/newforms) is a work in
progress, but should be solid enough for the common use cases.

Of course, any suggestions on how the docs could be improved are
welcome, and any contributions of improvements are also welcome
(although they will probably be edited).

Newbie Question: Static Media With Development Server - Not The Same Old Question

[cjl]

Djangoholics:

I am working on a portable Django development environment for windows,
and I'm trying to write a tutorial for newbies to go along with it.

My initial -- poorly executed and incomplete -- website is at
http://www.instantdjango.com

One problem I am trying to overcome is how to make paths relative, as
I want this environment to work from USB thumb drives.  Right now it
does this by executing a stupid and simple batch file, which actually
seems to work, for the most part.

It appears that using the Django development server I can use a
relative path for the template dir in 'settings.py', which is working
fine.

However, I am stuck on how to use relative paths for serving static
media from the development server.

Any ideas on how I might tackle this?

Many-to-many using intermediary table

[Jarek Zgoda]

I have to rewrite large parts of older code where we used plain M2M
without defining intermediary table. Now the junction in intermediary
table must get few additional fields so I guess we need to create the
model for the junction table and add these fields there, defining
ForeignKeys to both data tables. Unfortunately we had 'related_name'
defined on M2M fields and current code relies on this feature heavily.
Anybody can suggest the solution that wouldn't require rewriting all the
code that used related name? I just cann't imagine how can I do that...

BTW, we're on 0.96.

Multiple Edit

[Christopher]

I've been looking for a way to have a model and in the Admin be able
to edit a couple at one.  Is this even possible?  I know models that
have Foreign keys etc to each other this can be done.

I want one model, stand-alone, and edit multiple.

class Test(models.Model):
name = models.CharField(maxlength=30)
description = models.CharField(maxlength=200)

etc etc... and then have an Admin option or something for multiple
edits like the form would look something like:

name: | |  decription:
||
name: | |  decription:
||
name: | |  decription:
||
name: | |  decription:
||
name: | |  decription:
||

| save |

Thanks :)

You could run through the request.POST's keys and assign them to the
Model's attributes:
b = Book()
for key in request.POST.keys():
---b.__setattribute__(key, request.POST[key])
b.save()

Newforms is the replacement for the old manipulator framework. The old
forms framework was based around the concept of Manipulators. The
manipulator framework was starting to become a maintenance problem, as
their were some problems with the underlying architecture that were
exposing some nasty bugs.

So - we went back to the drawing board, and the result is newforms.
The format for defining forms, fields, and widgets is much cleaner and
much more extensible. The forms themselves look the same (they are
just HTML, after all) - but the view code you use to interact with
them is very different.

Oldforms (and manipulators) are now deprecated; they will remain in
the next Django release, but will not be present in v1.0.

In short, if you are starting out with Django, newforms is what you
should be using.

Yours,
Russ Magee %-)

No it doesn't - "price" is defined as a ForeignKey to Price, so it holds
a Price object.

The only integer defined is Price.name. Does this work:

 pr = pr + a['choice'].price.name


?

I would suggest that you change the name of that field ... "name" does
not really convey that this is the value of the price - it sounds more
like a label for it (like "SuperSaver").

Perhaps you could get rid of the Price class altogether? If it just
holds an integer, you could use an IntegerField directly in Choice ...

Re: Django, python 2.5 and macports 1.5

[Benoit Chesneau]

If you look the port source, you will see files/patch-setup.py in
which it disable md5 and such things like openssl. The only way to
have them back is :
1) modify this patch,
2) increment the release number in portfile
3) reindex all the port tree with portindex
4) finally reinstall the port after deinstalling old one.

I should open a bug about it one day...

Benoit.

HttpRequest.get_full_path() does not work with Apache 2.x

[Mambaragi]

Hello,

I use HttpRequest.get_full_path() for saving current url.
When I use this with Django manage.py runserver, it works perfectly
fine.
But when I use get_full_path with Apache + mod_python, it does not
work. I only gives me HttpRequest.path value without QUERY_STRING.
I just use like the following

def some_view(req, id):
  return_url = req.get_full_path()
  return render_to_resposne("/some.html", {'return_url': return_url})

What should I do for getting proper full_path?

Regards,
KwonNam

Re: Django advocacy in a commercial environment

[Jon Atkinson]

Thanks for your reply, Rob.

Personally, the reason we're looking to push Django is that our
business needs very much match a statement Simon made in the talk I
mentioned above: 'Web development on journalism deadlines' (that might
not be entirely accurate).

I was also considering putting together a report, but we all know the
problems with code metrics - do we measure LoC, speed of development,
or the very nebulous 'simplicity' concept which will be quite
difficult to communicate to management.

I don't mean to pry, but at your workplace have you had any difficulty
hiring into Python/Django roles at your company (compared to PHP)? Do
you get less applicants? A better quality of applicant?

Cheers,

--Jon

shortcut for assigning values to model?

[james_027]

hi,

is there a short cut for assigning input data to model's data
attribute?

if Book is a model then

b = Book(request.POST)
b.save()

the assignment will be done on all the match key of  the request.POST
QueryDict and data attribute of the Book Model.

or

if BookForm is a newform then

bf = BookForm()
if bf.is_valid():
b = Book(bf.cleaned_data)

thanks
james

Django, python 2.5 and macports 1.5

[lars]

Hi all,

yesterday I tried to install django on my macbook. Since I wanted to
have a more recent python interpreter I installed the one from
macports.
There's a pitfall, however. Because in order to get MD5 running you
have to install the package py25-hashlib as well! Otherwise you will
face the "ImportError: No module named _md5" error.

Just wanted to post this hint in case someone else runs into the same
problem :-)

Re: newforms

[james_027]

Hi Alper,

I am very new to django so I dont know how does the oldform look like,
anyway here is what I like in this new form

* helps me create the necessary html code to use in my forms very fast
(needs some enhancement, I've already create a ticket)
* with new forms you can handle forms for partial fields of a single
model, fields from multiple model, fields that even does link to a
particular model at all
* validation is cool, easy & nice

cheers,
james

Re: Problem with image upload

[Nathan Ostgard]

Use forms.ModelChoiceField instead:

immagine =
forms.ModelChoiceField(queryset=Pics.objects.all().order_by('immagine'),
cache_choices=False, label='Pic', required=False)

Usage of {% trans ....%} tag in templates related to inclusion tags

[Peter Melvyn]

Hi all,

I'am embedding a piece of information into each page using inclusion
tag and it seems everything works fine except tag {% trans ... %}. Its
occurence in the inclusion template raises expcetion
TemplateSyntaxError saying "Invalid block tag: 'trans'".

Did I miss anything or it is neccessary to translate text out of the
template and pass it as an item in the dictionary returned by
underlying function?


Thanks, Peter

Re: schema evolution

By casting a quick eye over the patch, I caught at least two reasons
that this hasn't been merged (or taken particularly seriously by the
core developers):

- No tests.
- No documentation.

I agree that schema evolution would be a valuable addition to Django.
However, if you (or anyone else) is serious about getting this into
trunk, adding a comprehensive test suite and draft documentation is a
non-negotiable prerequisite for .

The testing requirement is especially relevant for schema-evolution
because I suspect the existing test framework will require some
modifications to enable models to be evolved during a test run. If you
want to prove to me that you are serious, show me the tests.

Yours,
Russ Magee %-)

Problem with image upload

[ilDave]

I've a form that handles file uploading to the database: it works
fine, the file is uploaded in the right place and the path is written
on the database (I use a models.ImageField field in a model).

Than I have another form, that uses newforms, with a  field
that should be populated with all the images path inside the db:

class MyForm(forms.Form):
imgchoice = [('', 'Select:'),]
imgs = Pics.objects.all().order_by('immagine')
for i in imgs:
imgchoice.append((i.id, i.immagine))

immagine = forms.ChoiceField(choices=imgchoice, label='Pic',
initial='', required=False)


The problem is that if I insert a new image and that I open the other
form, the image that i just uploaded does not show in the select
field.
I'm using Apache and mod_pyton, and I noticed that if I restart Apache
the new images whow up.

How can I do to resolve without the need to restart the webserver?

Thanks.

Problems with fastcgi and pidfile

[Nis Jørgensen]

I cannot seem to get
manage.py runfcgi pidfile=myfile.pid
to work unless I have
daemonize=false
 as well. I haven't started investigating what actually happens -
thought I'd hear if I am doing something stupid first.

Django is [EMAIL PROTECTED], Debian Etch, python 2.4.4, flup 0.2126-1

Sample output below. Any idea why this doesn't work.

Nis

# This is how I've been doing it until now:

$ ./manage.py runfcgi host=127.0.0.1 port=8001
$ netstat -l |grep 8001
tcp0  0 nohouse.cust.gigah:8001 *:* LISTEN

# This doesn't work for some reason

$ ./manage.py runfcgi host=127.0.0.1 port=8001 pidfile=fcgi.pid
$ netstat -l |grep 8001
$ ll fcgi.pid
ls: fcgi.pid: No such file or directory

# This does work.

Hi,

there is a newforms admin branch. I think you can use this as an example.

I have not look at the branch up to now. I use newforms, but often I look
into djang/newforms/*.py to find how to use and misuse it.

Re: Mapping models to CRUD urls?

Don't let the fact that the data is dynamic distract you. All database
backed websites are dynamic at some level. However, when you have
thousands of requests for a resource every second, does it really
matter if the version delivered to the user is 1 second out of date?
10 seconds? A minute?

You should be able to serve a reasonably sized Django application
without ever having to care about caching. However, It pays to get
into a good habits early. It is a lot easier to add caching to the top
of a clean ReSTful application than it is to refactor a messy,
non-ReSTful application so that you can add caching.

As a bonus, URL spaces that are easily cached are also the ones that
match the browsing metaphor the best (i.e., are ReSTful), so asking
the question "could I cache this" is one way of validating a design.

Yours,
Russ Magee %-)

Re: Mapping models to CRUD urls?

[John M]

Russ,

Wow, thanks so much for clearing that up, I was never sure about the
parameters part of the URL, since this is my first real web program
EVER, and I figured django was the right way to go.

Does caching matter that much in my example, since it's dynamic data
anyway?

John

### this approach should work . Do you use it for your app? Any
experiences?
