Unfortunately there is a problem in that case (foreign keys with lots of
related data). It is ticket #2638.

Indeed, this feature is important to me too. I'm planning to implement

Re: User id foreign key

[[EMAIL PROTECTED]]

You have to do something like this in your model:
user_created = models.ForeignKey(User, related_name="user_created")

Then instead of saying User.entry_set .. I think its just
user_created_set ... but not positive on that.

You have to do this normally when you have two ForeignKeys on the same
class both referencing User  ( don't ask me why.. I haven't figured
that part out yet )

Any known issues with ChangeManipulators and large objects?

[[EMAIL PROTECTED]]

I was just wondering if there were any known issues regarding speed
with ChangeManipulators and large objects?

I'm using custom ChangeManipulators successfully on about 50 pages
right now... but when I did an edit page for one of my largest
database tables ( about 50 columns... and about 20 of them are foreign
keys to other objects that also contain foreign keys ), my page load
time shot up to about 30 seconds.

If I comment out the line where I instantiate the custom change
manipulator..and just pass None in for the Form ... it loaded fast
(obviously blank forms load fast..heh).  So then I decided to rewrite
the page using old fashioned forms where I set the values on each
field in the template via the object...and it went really fast then
too.

I could paste the code in here..but I wasn't doing anything fancy.. I
was just flattening the data from all of the objects...then loading
the form...so thought I'd ask on the off chance if others had seen
this happen?

Re: debugging/breakpointing

[[EMAIL PROTECTED]]

I'm probably be getting way deep over my head in this since I'm not a
Django user and stuff like command completion is a little bit open-
ended.

However pydb (http://bashdb.sf.net/pydb) has some support for command
completion and at least tries to save it's history across sessions in
a file called ~/.pydbhist if you have "set history save on".

It also has some support for ipython; possibly it will be a little
better in the next releases of ipython and pydb.

In recent pydb releases "set_trace" is called "debugger", since I
think that's a more natural name. (However for die-hard Pythonistas,
"set_trace" will still work.) But having put in a plug for pydb,  I'm
not sure I'd recommend this unless you are willing to dig in to fix
problems you find really annoying. Hopefully pydb may be a little
better organized for fixing problems, but probably not by much and it
could stand quite a bit of rewrite.

Some of the issues in command completion have been written about
here:
http://mail.python.org/pipermail/python-ideas/2007-February/000202.html

And I'll add to the above one other practical issues regarding command
completion: it's been a real pain to deal with the surrounding
context. For example, if invoked via Emacs gud you have one set of
protocols and if ipython another, and if a regular term another, and
if Emacs calling ipython calling pydb..., you get the idea.

If you want to not deal with pydb but  want to  improve pdb instead,
probably adding history across sessions is the easiest thing to fix.
Basically you'd need to add calls to readline.read_history_file() and
readline.write_history_file().  (Of course, you could consult the pydb
code for how to do that.)

Lastly, I don't have any time to work on pydb, so I hope this helps.
Good luck.

Chaining ManyToMany Filters Update

[Boris Smus]

Dear Djangoites,

I ran into problems trying to chain multiple filters on a QuerySet
with models in a many-to-many relationship. Based on the word from
irc, and from perusal of the mailing list, it seems that this is a
known issue. But the last ML post on it (that I could find) dates back
to 2006-08. Has any progress been made, and is there a workaround? I'm
on the latest svn.

For reference, an illustration of the problem:

In [54]:cs.filter(default_recipe__ingredients__ingredient__id=1)
Out[54]:[, ]

In [55]:cs.filter(default_recipe__ingredients__ingredient__id=3)
Out[55]:[]

In
[56]:cs.filter(default_recipe__ingredients__ingredient__id=3).filter(default_recipe__ingredients__ingredient__id=1)
Out[56]:[]

Thanks,
B

In general, you don't -- this is a limitation of HTTP, because once
you send out the response, you've sent out the response. You don't get
to send any more data until a new client request comes in.

Using a meta refresh is somewhat hackish, but would force a periodic
reload for anyone who's just sitting there looking at the page.
Similarly, firing off an occasional XMLHttpRequest to fetch updated
data will work, and is a bit cleaner.

There's also Comet, which is a method coming out of the folks behind
the Dojo JavaScript toolkit, and which is based on servers keeping
long-lived HTTP connections open so they can keep sending data down
the wire, but unfortunately the load of supporting even a few clients
in that fashion can quickly murder your server.

I'm in the exact same position as you. I use Address for quite a few
tables: Orders, Shipments, Customers, People, Warehouses. It only
makes sense to have an Address object to hold this information.
Especially when an Order has three addresses.

I'm not worried about the admin interface so much though, so my first
solution was to write my own Manipulator, adding each address field
individually. This was a royal pain. I then tried some hacks to get it
to automatically happen, but realized that this was futile with the
pending newforms changeover.

I really think this usage case should be addressed in Django. There is
a basic clash between the relational and object-oriented side of the
Django ORM. In OOP you expect the parent object to have a pointer to
the child, and in relational models it's usually the other way. Django
so far has pre-determined that you must follow the relational model,
even though it strives to hide that with an OO layer.

I posted about this on the dev list and pretty much got ignored. I'm
not sure why the devs don't consider this important.

This is a problem already reported. See tickets #526 and #2470, there is a

There is an open ticket about this argument: #3268.

I wrote a simple work-around:

choices = ( ('1', 'foo'), ('2', 'bar' ) )
myform = form_for_model(Gadget)
myform.fields['field_name'] = ChoiceField(choices=choices)

If you need to use form_for_instance remember to update
the initial value or you will not see the saved value pre-selected
on the select box.

choices = ( ('1', 'foo'), ('2', 'bar' ) )
myform = form_for_instance(Gadget_instance)
initial = myform.fields['field_name'].initial
myform.fields['field_name'] = ChoiceField(choices=choices,
initial=initial)

Hope this helps.

Re: User id foreign key

[Christian Hoeppner]

Thanks a whole bunch!

I got another error, saying like so:

blog.entry: Accessor for field 'user_created' clashes with related field
'User.entry_set'. Add a related_name argument to the definition for
'user_created'.

But I guess I can find out on my own. If anyone wants to reply for the
sake of completeness, it would also be great.

Thanks!

If you have Django print out the entire form's HTML in one go, it will
automatically add 'label' elements for each field. It will not (at the
moment) add fieldsets and legends.

It's also quite easy to output these yourself in a template, and only
have Django print the various 'input'/'select'/'textarea' elements,
allowing unlimited control over the organization and structure of the
form.

Re: (x)html tags used to render newforms

[anders conbere]

You can layout forms in django in which ever way you want. By default
the generic views don't use tables, and newforms has several
convenience functions that will display forms in a number of different
styles (as_p, as_ul). These are all standard html (as well as xhtml)
tags that should be supported by all browsers.

Unique_together question

[Rob J Goedman]

Earlier I noticed the problem with edit_inline which is now fixed in  
svn.
By the way, this was the very 1st time in 5 months a daily sync with  
svn caused
an issue. Hats off to the developers!

As I mentioned, I am trying to make 'day' and 'sch' unique_together in
class ScheduleDayOfTheWeek.

Any reason I can't combine these 2 fields to get a valid  
'isUniqueday_sch'
in the AddManipulator? Full traceback at the end of the email.

Thanks,
Rob

(x)html tags used to render newforms

[Frédéric Roland]

Hi,

I was discussing about layout of forms using CSS and heard that there 
was some tags such as fieldset, label and legend that should allow us to 
make the layout of forms without tables. Is there a reason these tags 
aren't used to render forms in Django ? Does it is hard to add them ? 
(Something like as_label() for example.)

Are these tags well supported by browsers ?

Having to validate the data at every possible form location doesn't
seem very DRY to me.  I should be able to put a single set of
validation rules directly in the model so any form I write in the
future has to validate against them.

The newforms page doesn't have much about validation on it:

http://www.djangoproject.com/documentation/newforms/

Do the same validation techniques apply from the old forms system to
the newforms?

That doesn't seem to be the case for this particular field I have:

class List(models.Model):
name = models.CharField(maxlength=32, blank=False, null=False)

> python manage.py shell
In [1]: import datetime
In [2]: from mysite.groceries.models import List
In [3]: l = List(name='', created_at=datetime.datetime.now())
In [4]: l.save()
In [5]: l.name
Out[5]: ''

What am I missing here?

Re: Django Automatic Page Refreshing

[sphogan]

There are two ways of doing this:

1) You can use a meta refresh so that every, say, 30 seconds, the page
reloads itself.

2) You can use Ajax to lookup if someone has registered every 30
seconds and then update the display based on the new data (or not if
there is no new data).

Unfortunately, there is no way to have it be instant.  For example, 1
person signs up and then the server pushes an update to everyone on
the site.  This is because HTTP is stateless.  The server has no idea
whether anyone using the system is still using the system.  When you
visit a site, your browser says to the server "hi!  i want this page"
and the server says "cool, here it is!" and then there is no
communication between them until you request something new.  The
server has no idea whether you're staring at the screen, whether
you've closed the window, whether you've shut down your computer,
etc.  As such, the server can't know who's still there to push data
to.

Suffice it to say, your best option would probably be to use Ajax to
send a request to the server and then update the data from the
response, but you will have to do it timed - you could pick every 5
minutes or 5 seconds, but do realise that your server and the person's
browser has to be sending and processing data when these requests
happen.

Good Luck!

Re: Django Automatic Page Refreshing

[baasbartels]

Not Django related, but well ... there you go

The short answer is: don't.

The longer answer is: Your room only holds 200 people, so at some
point someone will be out of luck. You just need to make sure that if
someone starts a serious attempt to book a seat (as opposed to just
browsing around), that he can complete the process in the assurance
that he'll get a seat/the number of seats he want. Therefor have a
'check for availability' step early (first?) in the booking process
and make a temporary reservation for that person for say 5-10 minutes
so that he can complete the booking process. Make sure to inform the
user of the duration of this temp reservation.

Rgds,
Jeroen

I haven't really tried it so this is probably just a wild guess, but the
form_for_model function has a formfield callback function that will be
executed on each field in your model and returns a new instance of the
FormField to be used for the respective field.

If you then instantiate your password field to use a CharField that uses
the PasswordInput widget I think it should work :-) (But again: Wild
guess ;-) )

newforms, choices and models

[enquest]

I'm using/learning the newforms... I got a model, in this model I have a
choices list ( ('1', 'foo'), ('2', 'bar' ) that are reprensented as
select box in the admin... 
However when I import this class to the newforms
"forms.form_for_model(Gadget)" the choices arn't coming along and the
field is reprented as a normal textfield... How come?

Second question: how can you add a password field from the newforms. you
can't define ("correct me if I'm wrong") a password field in the
model... And I don't see any option to give a field a password field.

How can I do this?

Thanxs

books the seat in the room, how do

I got some strange error, but I do not remebmber where and from what. But this 
looks like it could be the same problem (or not).

The solution was to add to the related object (User) the method 
def __str__(self):
so the problem disapeared ... maybe you can just try it ...

The query list only lives as long as the database connection, and
Django doesn't persist connections. If you just want to see what's
happening on the current request, the 'debug' context processor[1]
will make the information available to templates as a 'sql_queries'
variable, so you could drop something into the admin change list
template which, say, prints out 'sql_queries' inside an HTML comment.

Another option, if you want to log them over time, would be to create
a middleware class with a 'process_response' method -- it will be
called after each view has returned a response, and you could import
the DB connection there and write out the queries to a file.

Re: How to define non-persisted attributes in Model

[Horst Gutmann]

Do you really need a CharField here or would a simply string variable be
enough? So you could simply do something like

  class Message(models.Model):
 description = models.CharField(maxlength=200)
 author = models.ForeignKey(User)
 temp = ""

and it should never get stored in the database as far as I know... Or do
you need to have a CharField for a specific reason?

Ah, that might help if I can figure out where to call it from... Is
the list preserved across requests? Could I implement a view that I

Yup, I tried a regular constraint and an ^constraint. In both cases,
the result of a search is all items; no filtering/restriction of the
view happens. If I can figure out where to put the 'print
connection.queries' statement, I'll see whether the admin UI is
actually the search criteria to its queries.

Hmm, I tried a super-simple test case and it worked for me too. I'll
have to dig a but further to figure out what's causing the problem in
my main project.

I'm still a little bit confused, but here's what I'd suggest:

In the model you've described you can say something like:
BB.objects.filter(ab__aa__name="aa") to get the list of BB objects
that are mapped to that specific AA object.

In addition - if you don't have other fields in the AB model,
substitute that with a M2M field in one of the AA or BB models.  It
will allow you to use the full M2M relationship syntax in your
QuerySets.

Finally - those model names are giving us headaches. Sometimes it
helps a lof if you ask your questions in the context of your system
and people might have more clues and ideas for you.

When the DEBUG setting is True, Django keeps a list of all the queries
it's executed; you can see them by doing

from django.db import connection
print connection.queries

For searching in the admin, the default is to use the 'contains'
keyword filter on the QuerySet, which translates to 'LIKE %term%' in
the SQL. You can alter this behavior by adding operators to your
search terms:

^ at the start of a term turns it into a 'startswith' filter ('LIKE term%')
@ will cause it to use a full-text index search (currently only
supported on MySQL)
= before a term makes it look for an exact match.

This should definitely work (and does for me when I tested it just now).

Are you testing this against a full-blown webserver (Apache,
lighttpd, ...) or against Django's development server? In the latter
case, is anything displayed in the terminal window where you're running
the dev server?

Could you post the fulls models.py file that is causing the problems? If
I take your above model and add only

from django.db import models
from django.contrib.models import User

and put it in an models.py in an application, it works fine. So I'm
wondering what you have done differently.

In short, any extra information you can provide will be helpful here.

Regards,
Malcolm

search_fields: search is unrestricted

[Laurie]

If I set the Admin option 'search_fields' the admin interface gives me
a search field, but when I use it, I always get all objects. The
search criteria don't seem to be applied.

I don't think there's any way to get Django to log the SQL it's
executing, so I don't know if it's issuing any 'WHERE x ILIKE y' type
clauses, but functionally I'm not getting search filtering.

Again, using up-to-date Django trunk.

I think you are misunderstanding how OneToOne works: it is an explicit
join field between the tables, not an implicit (transparent) one. So in
order to access the fields of Place from a Restaurant class, you will
always need to use queries like

r.place.name

and so on. OneToOneField is not model inheritance. It provides similar
functionality in terms of linking models together, but the access
pattern is a little more cumbersome, which is why we are also
implementing more transparent model inheritance.

Not at the moment, no. Sorry. We're leading up to 0.96 at the moment and
I'm putting all my free time into that.

ForeignKey fields in list_display

[Laurie]

If I include a field which is a foreign key in my list_display admin
option, Django hangs. When using 'manage.py runserver' I'm unable to
get any further response from the app once this happens.

Here's an example:

class Test(models.Model):
name = models.CharField(maxlength=100)
owner = models.ForeignKey(User)

class Admin:
list_display = ('name', 'owner',)

When I go to the admin page that lists all Test objects, Django hangs.
If I remove 'owner', from the list_display tuple, it works as
expected.

Is this something that's not supported, or am I doing something
silly? :-)

I'm running the code from trunk (latest as of 5 minutes ago)

Thanks,

L.
