you have not specified which django version you are using. If it is trunk, I am 
under the impression that you need a Media subclass to your model.Admin class 
in admin.py to hold the tiny_mce settings. In older versions of django this 
was in the Admin subclass. btw, in a mailing list it is not advisable to paste 
in dpaste as that will vanish and b0rk the archives.

Re: Deploying django on apache - cant access database

[consiglieri]

Thanks Graham!

The absolute path was the issue. Can't believe I couldnt find that
anywhere.

As for the Alias, well i was just testing to make sure that wasnt an
issue.And its in the httpd.conf , for perl-cgi you need that so since
i was having issues i decided to try and see if it was causing my
issues. (Which it wasnt). As the apaches conf says

# ScriptAlias: This controls which directories contain server
scripts.
# ScriptAliases are essentially the same as Aliases, except that
# documents in the target directory are treated as applications
and
# run by the server when requested rather than as documents sent
to the
# client.  The same rules about trailing "/" apply to ScriptAlias
# directives as to Alias.

So i was thinking maybe i need to set an alias so that apache executes
the python scripts.

The only thing i have noted now is that that when i go to the admin
url the css doesnt seem to follow but probably its just a sethandler
issue.

Anyway Graham I really appreciate your input. At least now i know my
setup is working and I ca get on with actually developing the app
better as well as trying to master the django framework

django-tinymce not appearing in admin

[diogobaeder]

Hi,

I configured django-tinymce extension to work with a model field; It
loads all the JavaScript correctly, right after the field, in a script
tag, passing the right element ID, but the editor simply doesn't show,
only the original textarea is present. Here is a piece of my project
where TinyMCE configuration should be entered:

http://dpaste.com/hold/78621/

Anything wrong in here?

Thanks,

Diogo

Yeah, I did find those and then failed to revise the sentence.  I don't see
a template there for editing a user, though, just adding, changing password,
and confirming delete.  So I think the template for "Change User" is not
customized in any special way for User, it's the standard admin change
template.  So how to get a similar effect (which is what I was guessing the
real underlying question was) for a different model would be found by
looking at the UserAdmin ModelAdmin definitions.

Incorrect. See contrib/admin/templates/admin/auth/user. The general
capability to override templates on a per-model basis is generic. User
is the only model that exploits this capability by default.

However, that said, changing the template will only change the way the
information is displayed. If you're looking to actually change the
permissions, you'll need to look at the views, not the template.

You're trying to use Python syntax in the template.  Templates are not
Python.  Recall dictionary lookup in templates (what you look to be trying)
is one of the things done by dot in a template:

http://docs.djangoproject.com/en/dev/topics/templates/#variables

Also you probably want to review this doc:

http://docs.djangoproject.com/en/dev/topics/forms/#looping-over-the-form-s-fields

for some examples of how to loop over the fields in a form (and what all you
can access/display for a field) in a template.  Also this:

http://docs.djangoproject.com/en/dev/topics/forms/formsets/#using-a-formset-in-views-and-templates

for some formset-specific info.

Admin doesn't have special templates for certain models, so far as I know.
How a model appears in admin is controlled by the ModelAdmin class
registered with the admin for the Model. Since User is an auth model, you'd
want to look in django/contrib/auth/admin.py for the UserAdmin class.

I always goof up in pasting a traceback - never seem to get it right and 
always get screamed at ;-) btw, I did use cut and paste view from the debug

newbie queryset question

[joep]

I have a model which contains a list of users and a list of groups
that can access the model, e.g,,

readers = models.ManyToManyField(User, blank=True, null=True,)
reader_groups = models.ManyToManyField(Group, blank=True,
null=True,)

where User and Group are the standard django auth models. Now, given
that I have a user and his/her groups, how can I form a queryset for
the rows of the model that the user has access to? That is, I want
something like:

   select all rows where the user is in the list of readers
   OR the intersection of the user's groups and reader_groups is
not []

I'm kinda stumped. Is this possible?

long not to know that pasting a concise representation of the problem
helps us to help you.

Also the error is line 42 of the output you did paste. It says template
syntax error, so that's definitely the first place to start looking and
searching for the string reported in the template shows up the problem
fairly quickly.

Django's ForeignKey field is many-to-one. The fact that it happens not
to raise an error when you twist it slightly in the way you're doing
doesn't mean it's expected to work.

I'm not convinced there is a bug involved here, since you're not using
the ForeignKey class correctly. As far as I can work out, when
ForeignKey is used correctly, we always are going to be generating the
correct SQL.

I thought Django's "validate" management command raised an error when
to_field was used to target a non-unique field, but apparently I'm
hallucinating. That's probably an oversight in the implementation.

Malcolm

ModelForm subclasses don't include any AutoField values. By definition,
they are *automatically* assigned by the database. If you're using an
AutoField, you don't set it yourself. If you want to manage the primary
key value yourself, don't make it an AutoField.

Django wouldn't recognise a character field that stored the dates in
-mm-dd format as a DateField, either.

One of the reasons mmdd is quite a decent storage format is that
normal string sorting puts the dates in order. So why can't you just
order on that column as it already stands? You won't be able to do
anything like filter using the __month lookup type, because it isn't a
date field at the database level. But ordering shouldn't be a problem.

You can certainly convert the string values to datetime.date objects
easily enough, but that doesn't help with ordering in querysets, for
example, since that ordering happens at the database level.

I might be missing something here, but as far as I can make out,
you're getting exactly what you've asked for. Your query contains
filter(l=2) - that is, you're filtering on l, the SUM.

I'm afraid I don't see how this relates to your original question.

To be sure -- it's simply that this is a component that was covered in
the first edition, and appears to be something that would come up
pretty commonly in development. It just strikes me as a curious thing
to have decided *not* to include this time around. What led me to go
looking for it earlier this afternoon, actually, was the documentation
for a quite useful-seeming little application called django-profiles,
which directs one to "Chapter 12 of the Django Book." :)

Seeing as how Django's documentation still covers everything you need

It's true that the book doesn't quite cover everything everyone might
ever do with every feature of every component of Django, but
unfortunately people would complain if you threw a book that big at
them (even the online Django documentation, which doesn't come close
managing this feat, weighs in at around a thousand pages).

You're not doing anything wrong; you've just hit the limitations of inspectdb.

Django doesn't currently support database-level schemas. As a result,
inspectdb won't look into schemas to find table definitions.

Adding support for schemas has been proposed in the past, and has
received support from the core team. This means schema support will
probably be added in some future version of Django. However, this
doesn't necessarily mean that they will automatically be fully
supported in inspectdb - inspectdb is intended as a crutch, not as a
major part of the Django development process. The capabilities of
inspectdb have always lagged behind those of Django itself, simply
because introspection of this kind is extremely difficult to achieve.

Thanks Malcolm.  Not the answer I was hoping for, but good to know
that I'm not missing something obvious.

So, is there a way for me to get a form field out of a form from
within the templating language?  I'd like to do something like this:

{% for field_name in field_names %}

  {{ field_name }}
  {% for form in formset %}
  {{ form[field_name] %} 
  {% endfor %}

{% endfor %}

But this does not work -- Django chokes at the opening "[" with a
syntax error.

My other thought would be that I could try to add something to my
formset (a method called as_grid()) that could do the iteration in
Python and return what I need...but I could use a pointer on how to
get started with that.

I did exactly the same thing at exactly the same stage of my own

you get to trust the error messages.

Re: More Than Two Models With inlineformset_factory

[Geraldo]

Excellent, Matthias...  That should work nicely.  It does appear,
however, that there is no way to have more than 2 forms in a single
formset.  If inlineformset_factory had an append method things might
be a bit cleaner.

Thanks again for your help.

Your first regex is matching everything after /blog/ - including /blog/
category//. So your url is being dispatched to the first view,
which is trying to match a post with the title 'category/Andrew',
which obviously doesn't exist.

Either move the second URL above the first, or use \w+ instead of .+
to match only word characters within the slug, or preferably both.

Model example for simple family tree

[sniper]

Hi,
I am new to django and wanted to try it out.

I would like to create a table for family tree
where Relation is a many to many table which contains Profile ids

profile_id, relative_id,type,priority.

RELATIVE_CHOICES = (
(u'F', u'Father'),
(u'M', u'Mother'),
(u'B', u'Brother'),
(u'S', u'Sister'),
(u'N', u'Son'),
(u'D', u'Daugter'),
(u'H', u'Husband'),
(u'W', u'Wife'),
)

# Create your models here.
class Profile(models.Model):
first_name = models.CharField(max_length=20)
last_name = models.CharField(max_length=20,null=True)
gender = models.CharField(max_length=2, choices=GENDER_CHOICES)
birth_date = models.DateTimeField('birth day',null=True)
notes = models.TextField(null=True)


class Relation(models.Model):
person = models.ForeignKey(Profile)
relative = models.ForeignKey(Profile)
type=models.CharField(max_length=2, choices=RELATIVE_CHOICES)
priority = models.IntegerField(default=1)

how do i do that?
right now i am getting this error

Error: One or more models did not validate:
ftree.relation: Accessor for field 'person' clashes with related field
'Profile.relation_set'. Add a
 related_name argument to the definition for 'person'.
ftree.relation: Accessor for field 'relative' clashes with related
field 'Profile.relation_set'. Add
 a related_name argument to the definition for 'relative'.

thanks

Re: Deploying django on apache - cant access database

[Graham Dumpleton]

For SQLite database, the directory the database is in must also be
writable to user that Apache runs as. The location of the database in
settings file must also be an absolute path, can't use a relative
path.

BTW, what is:

  Alias test.django.com "/Users/someone/djangoproject/appname"

for in configuration? It will have no effect and normall your wouldn't
have anything like that in configuration for Django.

You can pass a prefix parameter when constructing the formsets (not
the formset classes):

Formset1 = inlineformset_factory(Parent, Child1)
Formset2 = inlineformset_factory(Parent, Child2)

if request.method == 'POST':
child1_formset = Formset1(request.POST, ..., prefix='child1')
child2_formset = Formset2(request.POST, ..., prefix='child2')
else:
child1_formset = Formset1(..., prefix='child1')
child2_formset = Formset2(..., prefix='child2')


This prefix will be added to all formset fields automatically. The
browser and Django will be able to differentiate between the two
formsets now.

Perhaps not.

Do you have anything to back this statement? (I'm not saying it's
untrue, I'm just trying to point out that this contribution wasn't
particularly helpful.

A bit more on topic: I've built an intranet application (sort of a
CRM) on Django, and I think it works great for this purpose.

Django aggregates and having

[lfrodrigues]

Hi,

I'm having some problems with "having":

I want to group by date and restrict to a given week, in my tests I
can do this:
select_data = {"d": """date_format(date, '%%U')"""}
ScoreHistory.objects.extra(select=select_data).values('d').annotate
(l=Sum("points")).filter(l=2).query.as_sql()

sql:
SELECT (date_format(date, '%%U')) AS `d`, SUM
(`profile_scorehistory`.`points`) AS `l` FROM `profile_scorehistory`
GROUP BY date_format(date, '%%U') HAVING SUM
(`profile_scorehistory`.`points`) = 2

Good but what I want to get is this:
sql:
SELECT (date_format(date, '%%U')) AS `d`, SUM
(`profile_scorehistory`.`points`) AS `l` FROM `profile_scorehistory`
GROUP BY date_format(date, '%%U') HAVING  `d`= 2

How can I force using having when I can't define the param in
annotate?

Thanks in advance,

Luis

The instructions also say to have configuration:


Order deny,allow
Allow from all


as well as other configuration, that being the location where you put
the .wsgi fle. Why haven't you done similar thing for your setup?

You also need an Alias directive and access configuration to make
available the media files. Again, you appear not to have done that.
Please reread the instructions and if above isn't all your
configuration you duplicated from documented instructions, also show
the rest and detail where you installed things on the filesystem.

More Than Two Models With inlineformset_factory

[Geraldo]

Hi,

I'm new to Django and am putting together a page for my new site.  I
want to be able to edit data that is contained in 3 models, organized
as follows:
Parent
 --> Child 1 (always one to one)
 --> Child 2 (one or more)

I understand I can do the following:

class Parent(models.Model):
name = models.CharField(max_length=100)
parent_type = models.CharField(max_length=10)

class Child1(models.Model):
name = models.ForeignKey(Author)
address = models.CharField(max_length=100)

class Child2(models.Model):
name = models.ForeignKey(Author)
gender = models.CharField(max_length=8)

# so I can do this to get a formset with Parent and Child1
Formset1 = inlineformset_factory(Parent, Child1)
dad = Parent.objects.get(name=u'Popeye')
formset = Formset1(instance=dad)

# or this to get a formset with Parent and Child2
Formset2 = inlineformset_factory(Parent, Child2)
dad = Parent.objects.get(name=u'Popeye')
formset = Formset2(instance=dad)

What I don't understand is how I get both child1 and child2 in my
formset?

Any help would be greatly appreciated.  Thanks so much in advance!

I'm going to second Antoni's take. Django and Python is probably about the
best choice you could make. Python has all the functionality you could
possibly need (and more if you really get into stuff like meta classes) and
Django just makes the entire development process a breeze.

With that said, it sounds like you want to connect to multiple DBs from a
single app. I don't have experience in the Django environment with multiple
db connections, though I know there is work being done in that direction.
Hopefully someone else here can shed more light on that.

What I would look at for now would be the connectivity availability to your
other systems. You can find info about Django direct support here:
http://docs.djangoproject.com/en/dev/ref/databases/#ref-databases

Though even if it's an odd type of storage system or the need for multiple
connections there should be way to do what needs to be done in Python.

Location of Change User admin template

[bfrederi]

I was browsing contrib/admin templates for the "Change User" template
that allows you to change the user's permissions and such. I can't
seem to find it though. Can anyone point me in the right direction?

Well, in my oppinion web application has sense because you are going
to forget about upgrading the application each time there is a new
version of windows, and makes the updates a pleasure. You can make the
applications as complicated as you want, you can use Django and add a
javascript front end (Dojo, Extjs, jQuery UI, Qoodoxx, etc) or just
give the users a simple  interface to do they work, you have both
options.

Python means you can make a rapid development and that you have lots,
tons of libraries and routines that are goint to help you. Actually
developing web applications for internal use has lot of sense and
protects your inversion, as the actual application you're making today
for internal use, coud be accessible from outside the company with
nearly no effort.

Just my two cents.

is Django a good choice for a LAN app?

[snfctech]

I'm about to start a fairly large project for a mid-sized business
with a lot of integration with other systems (POS, accounting,
website, inventory, purchasing, etc.) The purpose of the system is to
try to reduce current data siloing and give employees role-based
access to the specific data entry and reports they need, as well as to
replace some manual and redundant business processes. The system needs
to be cross-platform (Windows/Linux), open source and is primarily for
LAN use.

My experience is mostly PHP/web/app development, but I have developed
a few LAN apps using Java/Servoy (like Filemaker). I am leaning
towards Python/Django - but wondering whether this may be
unnecessarily web-specific. I really felt Servoy development was very
rapid, and it was cross-paltform, but it was not open source (not to
mention that anything custom needed to be Java which I find too
verbose/ slow to develop in). Or maybe Open Office Base and some
scripting is sufficient to handle my needs.

So, my main question is: Does a web framework like Django sound like a
reasonable platform to build a LAN Dashboard for a mid-sized company?
Or am I thinking too much like a web developer?

Any tips or suggestions would be greatly appreciated.

Django template language is just a template that is all done on the server
side of things. Javascript is client side and doesn't care about the django
template. It thinks (rightly so) that this is just a static web page.

So when you use variables from a Django template, you have to expect all the
output to be written literally. So the proper way to do this with the
javascript you gave is by putting quotes around the variable:
alert('{{ Your Variable }}')

Now when you view source, that is what Django is sending to your browser and
your browser then executes the javascript.

I hope that helps,

Michael

Re: syncdb with ForeignKey to_field outputs statements in wrong order

[physicsnick]

Actually they don't need to be unique (and I don't want them to be
unique). MySQL does not require that foreign keys be unique; only that
they be indexed.

I am actually using this for a temporal database. There are many
instances of an Author with the same code (an instance for each time
it was changed). In  relation to the above example I am having the
Author's default manager filter for live instances of the object, and
making it be used to resolve foreign keys via "use_for_related_fields
= True". This means the reverse relationship (book.author) gives one
object: the live version of the author with the referenced code. While
the foreign key itself is a many-to-many relation at the database
level, it is meant to be filtered to a specific revision of the
database to resolve its parent (hence many-to-one).

This already all works. The only problem is that syncdb is not
creating the tables properly; we have to manually create them all by
re-ordering the sql.

Re: Javascript with built-in templates tags

[WilsonOfCanada]

I want to access the string from the list that is in the dictionary:

function changeArea()
{
alert({{list_areas.British_Columbia}});
}

I get what I want in the generated HTML:

function changeArea()
{
alert(['Metro Vancouver', 'Metro Vancouver A', 'Sunshine Coast']);
}

However, when I tried using:

function changeArea()
{
alert({{list_areas.British_Columbia.0}});
}

I get this:

function changeArea()
{
alert(Metro Vancouver);
}
(it is not a string)

Re: Deploying django on apache - cant access database

[consiglieri]

Thanks for the tip, however it does not make a difference. I moved the
app to another catalogue and made sure that the database file was
chmod to 755 and also that all directories have the same permissions.
The error remains.

There is something happening that i dont understand. I'm beginning to
think there is someting wrong with the django or mod_python
installation but i am at a loss understanding what it can be.

[When ideas fail]

Hi, I have a strange error which i hope someone might be able to help
me with. Two of my urls seems to be conflicting somehow. i have these
two URLs:

(r'^blog/(?P.+)/$', 'mysite.blog.views.title_view'),
(r'^blog/category/(?P.+)/$',
'mysite.blog.views.category_view'),



which relate to two views which summarised are like this:

def title_view(request, category):
blog_post = Post.objects.get(post_slug=slug)
...
return render_to_response('blogSite/index.html', locals(),
context_instance=RequestContext(request))


def category_view(request, category):
blog_posts = Post.objects.filter
(post_tags__tag_name='category').order_by("-post_date")
...
return render_to_response('blogSite/index.html', locals(),
context_instance=RequestContext(request))



Title view works fine but if i go on mysite.com/blog/category/General
I get the following error:

File "C:\ProgLangs\Python25\lib\site-packages\django\core\handlers
\base.py" in get_response
  86. response = callback(request, *callback_args,
**calhttp://localhost:8080/akonline/blog/category/Andrew/lback_kwargs)
File "C:/Program Files/Apache2.2\mysite\blog\views.py" in title_view
  100. blog_post = Post.objects.get(post_slug=slug)
File "C:\ProgLangs\Python25\lib\site-packages\django\db\models
\manager.py" in get
  93. return self.get_query_set().get(*args, **kwargs)
File "C:\ProgLangs\Python25\lib\site-packages\django\db\models
\query.py" in get
  309. % self.model._meta.object_name)

Exception Type: DoesNotExist at /blog/category/Andrew/
Exception Value: Post matching query does not exist.

The error mentions File "C:/Program Files/Apache2.2\mysite\blog
\views.py" in title_view
  100. blog_post = Post.objects.get(post_slug=slug) but this
line is in the first view which works.

Category isn't going to match post)slug and it shouldn't so they seem
to be conflicting somehow.
I'd appreciate any help or even suggestion.

Thank you

Andrew

I am sorry to be a complete noob here, but I am not sure how I can use
SplitDateTimeWidget to break-up the two dat/time fields?

I am actually using django-schedule:



Looks like the author is already using SplitDateTimeWidget:



The docs:



Not much info there... Do I need to create my own widget for this?

All I want is to have separate control over the two input fields. :)

Again, sorry if noob question. I am new to Django and Python.

Thanks!
Micky

You have to make sure the database file is also readable and writeable by the 
user apache is running as.  The leading path should also be readable to the 
apache user.  755 settings on the directories in the tree.  

Some ways of fixing this are making a group; say djangodevs and add both your 
user and the apache user to that group and setting the sqlite file to be 
rwxrwx---.

You could run apache as your user by changing the User/Group setting in your 
httpd.conf/apache2.conf (see sample below) or a variation of this with the 
above suggestion.

# User/Group: The name (or #number) of the user/group to run httpd as.  
#  . On SCO (ODT 3) use "User nouser" and "Group nogroup".  
#  . On HPUX you may not be able to use shared memory as nobody, and the
#suggested workaround is to create a user www and use that user.
#  NOTE that some kernels refuse to setgid(Group) or semctl(IPC_SET)
#  when the value of (unsigned)Group is above 6;
#  don't use Group #-1 on these systems!
#   
User youruser  
Group youruser

I would personally recommend that you store your project files outside of your 
home directory, I believe/assume /Users/someone/ is your home directory. I 
would use something like /srv/djangoproject and configure the settings so 
both your user and the apache user can read write to the files through the 
group settings.

With a database like mysql/postgres that you connect to over a network you 
wouldn't need to worry about this since they have their own login.

Re: Apache mod_wsgi Django setup - Forbidden You don't have permission to access /mysite on this server.

Do you using a windows ou linux?
if it's linux, try:

create a dir: /home/user/django and put your project inside it and
create a file called mysite.wsgi in same dir containing:

sys.path.append('/usr/lib/python2.6/site-packages/django/')
sys.path.append('/home/user/myproject')
os.environ['DJANGO_SETTINGS_MODULE']='myproject.settings'
import django.core.handlers.wsgi

Re: How do I show generic relationship items with my generic inline on Django Admin page?

[chyea]

Oops. I don't mean to triple post, here, but I think the original post
might be slightly confusing.

When I say that I'd like to be able to select from existing
RelatedLinks, I don't mean that I'd like to view the existing
relationships between the new Entry model and the RelatedLinks model.
The generic.GenericTabularInline class already does this - it shows
existing relationships and allows you to add a new one.

What I mean is that I'd like to display what I mentioned above, which
is already there, PLUS be able to select from any existing RelatedLink
models, because they might be the "related link" that I want, instead
of having to just add a new one and duplicate the existing one.

Hope this clarifies this a bit.

Deploying django on apache - cant access database

[consiglieri]

Hi

I'm new with django and have made a small test app which works as it
should with the development server.

However when i try and deploy it with apache and mod_python I cant get
it to work. I have tested that mod_python works. I can do the
recommended mod_python test. When i try to run the django app via
apache it works well as long as the page being displayed does not
actually try and access the database. In other words if I enter a url
that just pops up an empty page with no django tags in it the page is
displayed as it should.

These are my settings.

Apache 2.2.11
mod_python 3.3.2-dev
I am on a Mac (Leopard 10.5.8)
I have the latest stable version of django 1.1

When I start apache the following can be found in the logs

Apache/2.2.11 (Unix) mod_ssl/2.2.11 OpenSSL/0.9.7l DAV/2 mod_python/
3.3.2-dev-20080819 Python/2.5.1 configured -- resuming normal
operations

The necessary settings in httpd.conf with regards to django is as
follows

Alias test.django.com "/Users/someone/djangoproject/appname"

SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE appname.settings
PythonDebug On
PythonPath "['/Users/someone/djangoproject/'] + sys.path"

When i run a url that invokes a function which tries to access the
database (sqlite3 in this case) i receive the following error

TemplateSyntaxError at /appname/clients/
Caught an exception while rendering: no such table:
addressbook_contacts

Original Traceback (most recent call last):
  File "/Library/Python/2.5/site-packages/django/template/debug.py",

len_values = len(values)
  File "/Library/Python/2.5/site-packages/django/db/models/query.py",
line 81, in __len__
self._result_cache = list(self.iterator())
  File "/Library/Python/2.5/site-packages/django/db/models/query.py",
line 238, in iterator
for row in self.query.results_iter():
  File "/Library/Python/2.5/site-packages/django/db/models/sql/
query.py", line 287, in results_iter
for rows in self.execute_sql(MULTI):
  File "/Library/Python/2.5/site-packages/django/db/models/sql/
query.py", line 2369, in execute_sql
cursor.execute(sql, params)
  File "/Library/Python/2.5/site-packages/django/db/backends/util.py",
line 19, in execute
return self.cursor.execute(sql, params)
  File "/Library/Python/2.5/site-packages/django/db/backends/sqlite3/
base.py", line 193, in execute
return Database.Cursor.execute(self, query, params)
OperationalError: no such table: addressbook_contacts

Now i know for a fact that the database does contain a table called
contacts. I have no problems whatsoever accessing this using the
development server.

As far as I can tell django seems unable to access the database when
going through apache and mod_python.
I have googled and I have searched to no avail. If anyone can give me
a helping hand I would appreciate it very much.

Thanks.

How to show the email field in a UserCreationForm?

[Berco Beute]

Hi,

I'm using the UserCreationForm for creating users, but I would like to
show the email, firstname and lastname fields as well (and they should
be required). Much like the view you get when adding a user through
the admin interface. What's the best way to do this? Extend
UserCreationForm? Or create my own forms from scratch?

Re: How to get this auto-field id value

Just a little more information. The autoField id is in the model
class.  Model_Form is a form based on this model class.

How to get this auto-field id value

[David]

Hello,

I am trying to retrieve an autoField id value in my following code
when I update records.

def update_record(request):
if request.POST:
form = Model_Form(request.POST)
if form.is_valid():
form.save(pk=form.id, force_update=True)

I got an error that "Model_Form" object has no attribute 'id'.

Model_Form is a model-based form class that has an autoField id that
increases one by one. When I update a record, I need to give this
value.

I even tried "pk=form.pk", however it did not work either.

Any suggestions how to fix this?

Thanks so much.

dropping django admin change password urls

[David De La Harpe Golden]

I'm using a simple ldap authentication backend, and the admin password
change functionality may need to be disabled or mangled to do the right
thing (currently going for disabled, can just redirect to different
password change form), as it  changes the django User model password,
which at best will have no effect.

I can sneakily drop the URLs with something like the following

admin_site_urls_except_password = (
filter(lambda x: getattr(x, 'name', None) not in ('password_change',
'password_change_done'), site.urls[0]),
site.urls[1],
site.urls[2],
)

# urlpatterns ...
(r'^admin/', include(admin_site_urls_except_password)),


... but maybe I've missed some obvious setting or approach I should be
using that might be ...less brittle?

(I then need to clone the relevant admin template to hide the
change_password link - Haven't worked out how to inject an alternative
named url, just merrily setting name='admin:password_change' on a url
doesn't work...)

dates with a different format in the db

[Vokial]

Hi!
In a db i have, already filled up with data, i have a varchar field
which contains dates formatted like "mmdd". Is there a way to make
Django recognise that field as a proper DateField even if the
formatting is different than the usual "-mm-dd" ?
Because i can't alter the data in that db and i have to order the
entries by date...
...maybe by defining a function that automatically decodes the string
into a datetime python object like strptime?

Any help is appreciated, thanks a lot!

can't get comment moderation working, following docs

[smcoll]

i was having trouble enabling comment moderation in my app, so i
decided to make a test app that would follow the docs at
http://docs.djangoproject.com/en/dev/ref/contrib/comments/moderation/
as closely as possible.

Unfortunately, moderation still isn't working for me:

- If i create an Entry with `enable_comments=False` i can post a
comment to it anyway.
- If i set the moderator's allow() method to always be False, i expect
every comment to be in the moderation queue.  None are.

It's as if the Entry model isn't registered with the moderator at all.

http://dpaste.com/78253/

Did i set something up wrong?  Are the docs incorrect/incomplete?  Is
there a bug in the moderation code?

method passing the field name and
and it's working now

Here is the code

def clean_csi(self, field):
data = self.cleaned_data[field]
data.sort()
csi_list = []
first_element = True
for element in data:
if not first_element:
csi_list.append(",")
else:
first_element = False
csi_list.append(str(element))
return "".join(csi_list)

def clean_hour(self):
return self.clean_csi('hour')

Thank you for your help !

I don't believe there is a bug.  The original description of the problem
confused me because I thought it was trying so specify unique_together for a
field in one model and a field in another model related by a nullable
foreign key, and I didn't think you could do that.  In fact you can't -- all
the fields have to be in the same model/table and I see now that the
original report wasn't saying that.  (The _field in the unique_together spec
is what confused me as I read that as having a double underscore.)

Anyway, form validation allows multiple allows multiple None/NULL values
here since most of the database backends interpret NULL != NULL at the SQL
level to mean that (NULL, v1) != (NULL, v1) when doing multiple field unique
checks.  The one exception I know of is Oracle, it apparently will raise an
IntegrityError for this case.  See the discussion here:

inspectdb and postgresql schema

[Marek Pietrucha]

Hello,

I have a relational database written in PostgreSQL 8.4. I use
different schemas - not default public schema. I tried to inspectdb my
database but the output was clean. It looked like the inspectdb tool
didn't look in my schemas. I thought it was the matter of the pg
driver, so I changed it from postgresql-psycopg2 to postgresql.
Nothing changed. The output was the same.

Is it possible to generate models from my database?

Am i doing something wrong?

Thanks for help :)

best regards,
mark

You are talking about in the forms/admin validation correct?  Thinking
to how this is implemented there likely is a bug where this doesn't
use the SQL concept of NULL != NULL and uses the Python None == None
instead, which of these behaviors is correct I'm not sure of (though I
lean towards the SQL interpretation).

Unless the majority of your data is from 1 table I'd try dumping each

individually.

Concurrent Web Access and Edits

[Doug Blank]

New Django user here with a question about the client side: Is there
built-in support for dealing with concurrent edits? I'm not referring
to the database issues (locking, etc) but is there Django support for
handling a request to access or edit data for which another user is
editing?

I'm thinking about simple timestamps, detection of changed data, and
showing the user options to abort, overwrite, or re-edit.

Does one have to implement this for saving data? Anything I should
read that covers this or related topic? I couldn't find anything on
the Django site, nor in this forum.

Thanks for any pointers!

session management problem

[Oguz Yarimtepe]

Hi all,

In my application i have a login screen. The view is simple as below:

loginform=None
formvalid=True

if request.method == "POST":
   
username = request.POST['username']
password = request.POST['password']
loginform=LoginForm(request.POST)

formvalid=loginform.is_valid()

if formvalid:

user = authenticate(username=username, password=password)
if user is not None:
if user.is_active:
login(request, user)
return render_to_response("menu.html", 
{"somekey":somevalue})

...


menu.html has some menus. One of them had the address of "localhost/add" which 
is defined in urls.py also. The view for add, is also add. But at my add 
function it seems i lost my session. 
if not request.user.is_authenticated():
return HttpResponse("nok")
else:
return HttpResponse("ok")

So i am gettig alwasy nok on the screen. How can i keep accesing session values 
from not posted sites?

Extending Django-cms Menu

[Alessandro Ronchi]

I have a django-cms app with this menu:
- Apples
 -> Red Apples
 -> Green Apples
- Oranges
  -> Big oranges
- Lemons
  - New Lemon types

I must add another link (a blog category) to Apples and Oranges first level
menu, to achieve this result:

- Apples
 -> Red Apples
 -> Green Apples
 -> Blog (apples)
- Oranges
  -> Big oranges
  -> Blog (Oranges)
- Lemons
  - New Lemon types

I've tried to extend the category of my blog putting this code:
http://dpaste.com/78219/

this utils:
http://dpaste.com/78220/

and added this setting:

CMS_NAVIGATION_EXTENDERS = (('blog.utils.get_nodes', gettext('Blog')),)

But it doesn't work.

Any ideas?

Any other working example?

Is there a django-cms dedicated mailing list?

It appears that the security fix that was committed in r11354 was
missing a file. I have committed the missing file in r11430.

As a temporary workaround, you can download the missing file
(django/utils/_os.py) from the Django source code browser [1]. If you
drop this file into the django/utils directory wherever you have
installed Django, you will be able to run the development server
again.

A new release that includes this missing file will be made in the near
future (time permitting, within a few days).

I deeply apologize for any inconvenience this has caused.

Re: Django for smaller sites

[Gustavo Henrique]

Django is the best option for websites. It's very good for e-commerce,

IMHO, the bests frameworks are:

1. Django
2. Rails
3. CakePHP
4. Code Igniter

PS.: I tried all php frameworks, but python frameworks only django.
See about web2py too.

I'm looking at using django for building my sites. I want to be able
to build sites of varying size but the likelyhood is i'll be creating
a number smaller low traffic sites. I was wondering if django is
suitable for smaller sites ( simple cms, contact forms etc ) or would
it be overkill ?

Would I be able to host as many sites on a 256 slice from slicehosts
using django as I would if the equivilent sites were built using
something else (php codeigniter for example) ?

Thanks.

Re: looping over forms in a formset

[bnl]

Thanks.

Before I suggest anything concrete for the docs, let's see if my
understanding  is now right:

The problem from my point of view was that I didn't think I had any
hidden fields. Hence I didn't loop over them, and didn't think of
them  - yes, despite the massive hint in the error message ... :-(

I think the hidden field in question was in fact the id of the
instance (which exists for the previously saved objects) and was zero
for a "blank" form in the formset ... and I think this only shows up
as an issue when looping over forms in a formset, because the formset
machinery has set up, modified, and uses this hidden field - and I
didn't know it was there.

(Or is it always there for anything generated by a ModelForm, and I've
never spotted it because I always get my id from my url?)

(Is this really an edge case? It seems like something one would want
to do for nearly any interesting formset ... lay it out nicely ...)

Cheers
Bryan

unique_together with None

[gentlestone]

if I have

unique_together = ('some_fk_field', 'some_plain_field')

and

some_fk = ...(null = True)

the system allows put more intsances with some_fk_field=None and the
same some_plain_field value

I think, this is a bug. Or how can I manage to allow just one instance
with null fk and the same other field value?

Re: IE problems w. admin save

[Jesper Rasmussen]

I've made some more experiments, and it does seem to be a (database?)
timing issue: About once in 10 it shows the right page :o|

My model is quite big ... about 40 entries of mixed types many having
both blank and null.

If nothing else works ... and good ideas of where to put in some pause
to "solve" the problem?

Jesper

Re: Standalone script with django's ORM and multiprocessing

I've checked that. Unfortunately, in my case, it won't work. I have a 
loop looking like this:

for job in joblist:
p = Process(target=self.run_job)
p.start()

When i close connection before this loop i get errors like at the 
beggining. When i close connection just before creating a new process i 
get: 'lost connection while performing a query' (or something like that 
:)). Finally when i close connection just right after this loop it 
starts to behave weirdly. One time it works fine, but next time i launch 
it i get mysql has gone away errors. I suppose this happens because 
sometimes subprocesses fire up queries after parent finishes this loop, 
but sometimes they're faster and still use parent's connection.

Closing connections in subprocesses might look a bit hacky. I could try 
to somehow reinitialize db connection, but simply closing it, and 
leaving the rest to django is a lot easier :)

Thank you for your replies. I appreciate it.

Regards
Spajderix

Re: Django: Add SET DATESTYLE

[Bdfy]

class ModelForm(forms.Form):
test_date = forms.DateField(required=False)

,,,

INSERT INTO SQL:

 obj.test_date = test_date

All OK for default format ( 2009-12-31 ). But for InputFormat
"30.12.2009" - error. How to change InputFormat for all forms in
application ?

Re: Dumping Large Databases

[Chris Spencer]

I guess I should have prefixed that by saying my goal is to migrate
from MySQL to PostgreSQL. However, I'm having trouble finding a tool
to do this, so I thought I'd try Django's backend neutral
dumpdata/loaddata feature.

That would also work.
