Re: Filtering the filters in Django Admin

[gladys]

I dont think there's a trivial way to do this. You might end up
hacking into the django code itself.

Re: testing foo_set existence for each object in a queryset

[Lior Sion]

Dan,

If I understand your question correctly, you are struggling with
creating the filtering you wrote in your message on the queryset level
(without going to the db for each object), right?

Hard to say without actually seeing your code and testing, but would
this be the same?

MyModel.objects.filter(foo_set__endtime__gt ==
datetime.datetime.now())

I don't think you'll need the exists, as only existing objects will
come back from the query.

Re: testing foo_set existence for each object in a queryset

[Shawn Milochik]

Not only is it not a stupid question, but it's one of the best
possible types of questions. Any time someone comes in and makes it
obvious that they've thought about their problem and made an attempt
to solve it themselves, they get my respect.

The easiest answer to your question is to make a custom manager (a
subclass of models.Manager) for your model.

http://docs.djangoproject.com/en/1.2/topics/db/managers/

You can add your logic to an override of the get() of filter(), or add
an entirely new method, such as pending() or ready_to_send().

If your data grows to the point where this becomes unwieldy, you could
speed things up by using signals, so that instances of the model
represented by 'foo' in your example would update a field in your main
model when they are created, changed, or deleted. This would allow you
to use metadata in your main model instead of having to do the extra
joins on every database read.

testing foo_set existence for each object in a queryset

[Dan]

Hi,

Long time lurker - first time poster - hopefully future answerer...

Basically what I want to do can be done with:

result = [w for w in MyModel.objects.all() if
w.foo_set.filter(endtime__gt = datetime.datetime.now()).exists()]

Is there anyway to do this using the queryset api?

Hopefully it's not too stupid a question...

Yes. In fact, in our company we wiped out our South stuff and started
over after almost two years (and many dozens of migrations across
several apps). We have the history in git, and didn't need the
overhead. When one app has over 70 migrations, unit testing becomes
pretty daunting.

All you have to do is wipe out the south_migrationhistory table and
delete the migrations, and it's like it's South's first day on the
job. It's great!

I was going to say the exact same thing. I can just add that anything
is fairly
easy with South - starting from the beginning, starting just before
2nd
dev joins in, or even starting after other devs join. Wiping out old
migrations
is also easy.

Re: urls.py and views.generic issue

[jnns]

Hi Antti,

the url patterns in the tutorial are not correct. The regular
expressions are not using character classes but merely plain
characters.

^blog/ ^(?Pd{4})/$
should be
^blog/ ^(?P\d{4})/$

Mind the backslash in \d{4}. This way we're matching for a sequence of
four digits and not for a sequence of four "d"s.

Regards,
jnns

[Antti]

The problem:

I can't seem to get most of my urls that I type in my browser to math
a url in my urls.py file.  I am currently doing Web Monkey's Blog
Tutorial (http://www.webmonkey.com/2010/02/Get_Started_With_Django/)
To date everything has worked but when I try to use the urls from the
blog urls.py I get the following error:

Using the URLconf defined in anttipetaisto.urls, Django tried these
URL patterns, in this order:

^admin/doc/
^admin/
^blog/ (?Pd{4})/(?P[a-z]{3})/(?Pw{1,2})/(?P[-w]

The current URL, blog/2011/jan/20/things-learned-finland/, didn't

What I don't understand why this is saying that isn't a url match.
Shouldn't it match the third one down?

Filtering the filters in Django Admin

[SimpleDimple]

Here is my code for a school project
http://dpaste.com/434311/

The code works fine, on studentadmin list page, I get filter for
classes
which is good but as you can see my project is multi-tenant so in
filter
area I want to show only the classes for the school the current user
is
logged in (tracked thru sessions) but right now I can see list of all
classes from all schools

so I want to replace this line
list_filter   = ['xclass']

with something like
list_filter   =
Class.objects.filter(school=request.session['school_id'])

how can I do it ?

Using contenttypes without auth

[xcephe]

If you use contenttypes without auth in INSTALLED_APPS (eg, being
used) it seems the auth models still get installed. When you run
syncdb with a state content type, it will prompt to delete the stale
CT entry and the Permission model tries to clean up:

  File "/home/wk/projects/rootproj/django/core/management/commands/

What's odd is that the tables correctly never get installed. Is
contenttypes not available for projects not using auth?

This is a basic Python question. When using import, you need to give the 
fully-qualified module that you are importing. As you can see from your own 
directory structure, you have a directory called 'abhivyakti', which is the 
application, and inside that is a file called 'models.py', which contains 
the actual model names (which you haven't given).

So either do `from abhivyakti import models` - and now you can reference 
your model classes via `models.MyModelName` - or `from abhivyakti.models 
import MyModelName`, and just refer to MyModelName.

No, allow_tags has nothing to do with textfields. 

Django doesn't encode text when saving data from a textfield. It does encode 
- actually, escape - the text when it is *output*, which you can avoid by 
marking it as safe with the `safe` template filter. But nothing will be 
changed on the way in.

Django administration - Allow full HTML for a TextField form

[NewNumOrder]

I've tried enabling 'allow_tags' for a TextField, but the admin tools
still encode the text when inserting or updating rows.

Is the following code correct?
some_field = models.TextField()
some_field.allow_tags = True

I can't even edit the HTML with phpPgAdmin because it does the same

I hope somebody here knows a way to edit HTML from a DB more

Django Aptana Run

Hello, 

i'm trying to get Django running in Aptana Studio. I've got PyDev installed and 
can create a new project. The point that's missing is the "run as". Does 
anybody know how to setup a run configuration.
(Im running it on mac, if that's important to know). Or is there a better dev 
environment to develop for django?

Andi

document_root is a file location, not a url location.

For most cases, using a user-specific queryset would be enough, for
example:

class BlogPostUpdateView(UpdateView):

def get_queryset(self):

return self.request.user.blogpost_set.all()


Which would restrict the ability to update only one's own blog posts.

For more specific requirements, a possible SecureMixin could do a post-
lookup check through a has_permission() check. The problem then is how
to handle non-permitted cases - probably another hook would be
required, with a default behaviour being e.g. redirect to login.

when trying out  ' from student_cce.models import abhivyakti ' command
where student_cce is name of my project model and abhivyakti is name
of my databse table it is giving me error : ' ImportError: cannot
import name abhivyakti ' where I have already defined abhivyakti as
model in settings.py. Please give me the solution.

django-taggit how to get tags based on foreign key

[easylancer]

I have a model [http://pastie.org/1582079] which I am trying to get
tags based on the Worksheet foreign key, so tags per worksheet. I am
unable to find any examples of ways how to do this?

I was able to accomplish this easily with django-tagging by doing
Tag.objects.usage_for_queryset(Cashflow.objects.filter(worksheet=1).order_by('-
date'), counts=True). How do i accomplish this in django-taggit?

Re: Just going to point this out ...

It would be interesting to perhaps extend something like django-lint
to pick up on what could be mistakes in templates.

TinyMCE + Filebrowser (can't make integration)

[gerram]

Help me anyone. I installed separately: 1) grappelli, filebrowser,
tinymce. Filebrowser works good, tinymce works good but if I try to
get widget of filebrowser from tinymce form (insert image) then I get
standart upload interface from tinymce. I want to get my filebrowser
interface.
In my app folder I made admin.py file:

from django.contrib import admin

class MyModelAdmin(admin.ModelAdmin):
class Media:
js = ['/static/tiny_mce/tiny_mce.js', '/static/filebrowser/js/
TinyMCEAdmin.js',]

admin.site.register(MyModelAdmin)

I can't find manual where I would take right advises for such
integration. Please, help me with settings.

Best regards, George

Re: Broken link emails

[pjrhar...@gmail.com]

I realised the second question is answered here:

http://docs.webfaction.com/software/django/troubleshooting.html#accessing-remote-addr

which is a middleware that was removed a while back.

The first bit of my question still stands though!

Re: Constant signing out on production server - Django 1.2.5

I'm glad I'm not alone, but this seems to be a different issue. The
client gets the same issue in ANY browser, which makes the problem
either more mind-boggling or much easier to solve if the problem is me
and I'm missing something major :)

The intention for 1.3 was to get a class-based view framework in place
that could serve as a replacement for the existing function-based
generic views. Since the function-based generics don't have
permissions, neither does the initial iteration of class-based views.

At this point in the 1.3 cycle, there aren't any new feature plans for
class-based views -- we're just making sure that there aren't any
glaring bugs in what is already in trunk.

Once we start the 1.4 cycle, we can take a closer look at suggestions
like adding permission support to CBVs.  If this topic is something
that you have a particular interest in, I encourage you to tinker with
the code that is there and see if you can develop a concrete proposal
for this feature; that way, when formal feature discussions start,
you'll be in a good position to drive a discussion.

Yours,
Russ Magee %-)

Permission hooks in class-based views

[fordprefect]

Hi, looking at the new class-based views for 1.3, there doesn't appear
to be an easy way to add row-level permission hooks to the views (as
one can do in ModelAdmin). It seems a strange omission as this should
be quite straightforward and is an extremely common use-case.

For example, if I have a BlogPostEditView I should be able to specify
a has_permission() method, e.g.:

class BlogPostEditView(UpdateView):

 def has_permission(self, inst):
  return request.user.id == inst.author_id


Are row-level permissions in the works for class-based views ?
