I don't know about grappelli, but I'd expect it to be at least as
configurable as the standard django admin interface.

You can create a user and assign them permissions only for certain
apps/models. Just don't give them superuser permissions. The apps
where users do not have any permissions will be hidden.

I think these aren't possible currently.

Admin dashboard : hide and merge modules

[JF Simon]

Hi men,

I'm using Django + Grappelli and I'd like to know if there is a simple
way to make some improvements to the dashboard (index) of the admin
such as :

- hide modules (like Django_Evolution)
- merge modules (Auth entries with my User module)
- rename existing modules (not for now, just to know)

I dont found anything so I'm not sure anyone can help...
Thanks for all (even if there is no way to do that !)

Thast's because you are mixing strategies for specifying the admin entry
on the URL map. Compare the relevant highlighted lines in the urlpatterns
variable assignment in the following documentation code excerpts:

http://docs.djangoproject.com/en/1.0/intro/tutorial02/#activate-the-admin-site
(Django < 1.1)

The idea is that the profile page(what i have in my mind at least) is
visible to all, but according to if you
are logged in , it is your profile-home page. Or your friend's and you
can leave comments,
for example...

nice idea, i will definitely try it! but then where do you use custom tags?

Re: Django-tinymce and filebrowser, error.

[diogobaeder]

Hi,

Are you guys using the TinyMCE media files from a domain different
from your admin site location? If so, you must point the media files
(or at least the tiny_mce ones) to the same domain, because this addon
tries to control the parent window from the popup window, and, if
they're different, the popup ends blank, with strange titles. That's
because the popup can't control the other window, limited by same-
domain restriction.

Regards,

Diogo

Admin site : Redefining __init__ method for Form

[Julienoune]

Hello django users,

I'm trying to override the __init__ method in forms.py for an
application that extend the admin site.
I'm doing this to initialize a ModelChoiceField of the form with user
logged in, informations, so I'm trying to retrieve the user in my
__init__ method... but I think I'm missing something :)

So my code is the following (python 2.6.2/django 1.1):

class InscriptionForm(forms.ModelForm):
equipe = forms.ModelChoiceField(queryset=Equipe.objects.all(),
required=False  )
def __init__(self, *args, **kwargs):
super(InscriptionForm, self).__init__(*args, **kwargs)
try:
user = kwargs.get('user')
if user.get_profile().evenement:
self.fields['equipe'] = forms.ModelChoiceField
(queryset=Equipe.objects.filter(evenement=user.get_profile
().evenement), required=False  )
else:
self.fields['equipe'] = forms.ModelChoiceField
(queryset=Equipe.objects.all(), required=False  )
except:
self.fields['equipe'] = forms.ModelChoiceField
(queryset=Equipe.objects.all(), required=False  )

My issue is that I never put explicitly the user in the call of the
__init__. I supposed that is the admin internal mechanism that do the
stuff, but I can't figure out where... so my kwargs.get('user') return
nothing, that is pretty obvious.

So my question is : how to retrieve the user logged in an AdminForm
element???

Thx guys.

Julien.

Re: ways to implement a user - profile page

[Berislav Lopac]

Just a couple brief thoughts.

First, there is no need to have the username in the URL if this page
is visible only to the logged-in user. Instead, use the request.user
object inside your view (and, if necessary, the template).

Second, to retrieve various info about the user there is no need for
custom tags. Instead, use the ORM to retrieve the related objects
directly.

For example, imagine you have the model Comment which has the User as
its ForeignKey; you can then use request.user.comment_set to retrieve
all the comments made by that user. Or, as I prefer, use related_name
in the Comment model definition, so you can do e.g.
request.user.comments. For friends you would probably need a
ManyToManyKey field, but the rest of the logic is the same.

Admin add / list / etc links broken?

[ringemup]

I'm sure I'm doing something wrong, but I can't figure out what.  The
list, add, and change links on the admin index all point to the
correct URLs, but all URLs under /admin are returning the admin index
page rather than the appropriate views.

Using the following urls.py under Django 1.1:

from django.conf.urls.defaults import *

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',

# Uncomment the next line to enable the admin:
(r'^admin/(.*)', include(admin.site.urls)),
)

Interestingly, using admin.site.root instead of include
(admin.site.urls) works, but my understanding is that the older use is
now deprecated, so I'd like to get this working.

Any suggestions on what I've screwed up, or how to debug this?

Thanks!

Weird: the path to the image, retrieved using filebrowser, is rewritten with a wrong relative instead of absolute.

[Cody Django]

I really don't know what is going on here.  I've checked all my
settings for django-filebrowser and django-tinymce.

1) Using tinymce in admin, I'll click on "add image"
2) Click on "filebrowser" icon in the image-prompt window, which opens
the filebrowser window
3) Click on an image, which opens in a window
4) Copy the absolute address from the url
5) Paste it into the url field in the image-prompt window and click OK
6) Image is now viewable in the textarea.
7) click view object on site
8) image has a broken link.  I check the path for the image and it's
something like:  instead
of the absolute path.

* I've managed to have it display the absolute url if I include a www
in the absolute url field in the tinymce image-prompt window:

ect:  http://www.site.com/static/testimage.jpg   (image url becomes
'http://www.site.com/static/testimage.jpg')
 instead of
http://site.com/static/testimage.jpg  (image url becomes '../../../../
static/testimage.jpg')

Re: Using custom table instead of "user" in django

[PlanetUnknown]

Thanks Jonas.
Quick question - The difference in the models.py is I guess addition
of these two imports -
from django.db.models import get_model
from django.conf import settings

A dumb question, when you say "moved it within the pythonpath", what
exactly does it mean ?

ways to implement a user - profile page

[Nicolas Aggelidis]

hi, i am new to django-universe. My goal is to make to make my first
django application!

I am trying to get  a grip on the authentication system. I 've
implemented login and logout operations. After a successful login i
want the user transferred to his profile page.

The profile page url looks like this: profiles/username.
In this page will see:
- a personal welcome message with his name
- his avatar, his friends avatars
- latest comments from friends and stuff like this.

I was wondering which is the suggested way to implement this page.

one way would be to have custom tags like:

get_latest_entries
get_friends


another way would be to have a custom view function pass all this
info... Is there any other way? which one would be the preferred?


thanks in advance for your time and comments!

I would only store the PK in the session and use it to get a new

Model instance refreshing

[mettwoch]

Hi,

I use a session to store several instances of different models coming
from a:

some_model.objects.get(pk = some_pk)

When the data in the db changes the model instances in the session
still contain the old data. What would be a good strategy to make
shure that all objects in a session get fresh data on every request?

If you're using the admin as the only way to upload files, I do this in one of 
my apps:

By customizing the save_model[1] to handle the upload of files, write the 
files to the savel location, then return the relative path for the files 
under my  MEDIA_ROOT, and save it to the imagefile field. 

class ImageAdmin(admin.ModelAdmin):
  list_display = ['name', 'gallery', 'date' ]
  search_fields = ['name', 'gallery__name']  
  prepopulated_fields = {'slug': ("name",), }
  list_filter = ['gallery', ]

  def save_model(self, request, obj, form, change):
def uploadHandler(f, saveLocation):
  savePath = os.path.join(settings.MEDIA_ROOT, saveLocation, f.name)
  destination = open(savePath, 'w')
  for chunk in f.chunks():
destination.write(chunk)
  destination.close()
  return os.path.join(saveLocation, f.name)
if request.FILES.has_key('imagefile'):
  obj.imagefile = uploadHandler(request.FILES['imagefile'], 
settings.GALLERY_SAVE_LOCATION)
obj.save()

admin.site.register(ImageFile, ImageAdmin)

The FileFields upload_to[1] option can also take a callable to handle the file 
fields location, this uploadHandler can be placed there for a more robust 
application.  

The keys are write the file by reading the chunks[3] to the place you really 
want it stored and then return the relative path  that's under the 
MEDIA_ROOT, then use the MEDIA_URL context processor[5] in your templates 
like  myfile.name

Re: Securing files held by FileField.

[stupidgeek]

Thanks a lot, Javier! There were a few caveats to getting this to work
for me, but I've gotten there, finally!

For anyone else who wants to use this solution, check out this posting
by a bloke named Andre, who was extremely helpful when I emailed him
asking for a bit of a hand: 
http://andre.liquidmm.com/blog/2009/mar/24/secure-downloads/
Also, here is the homepage for the module: http://tn123.ath.cx/mod_xsendfile/
And here is a .deb for all you Debian based people:
http://www.screenage.de/blog/2008/02/22/libapache2-mod-xsendfile-processes-x-sendfile-headers-with-apache2/

One extra note: if you are going above your DocumentRoot, you must use
XSendFileAllowAbove On - for some reason I thought this was optional,
and it caused me a couple of hours of 404s. Of course, Andre was
helpful in helping realise my silliness.

So, thanks to you all. This finishes my project for me =D

FileField problems - url attribute doesn't work, how do I do uploads?

[Fluoborate]

Hello All,

I am being very perplexed and annoyed by models.FileField database
fields. I have two problems:

1. The filefield.url attribute gives the path on my hard disk, not the
internet URL that the file is being served to. The filefield.path and
filefield.name attributes also give the exact same result as .url.

2. How am I supposed to make a form where the user uploads something?
I think I can hack something together by reverse-engineering the Admin
page, and by looking around on the internet, but I don't see one good
and simple example. I want simple.

My setup:

Mac OS X 10.5.8
Django 1.0.2
Development server only, at the moment.

#In settings.py:
MEDIA_URL = '/media/'
MEDIA_ROOT = '/Users/me/publications/'

#In models.py:
class Publication(models.Model):
pdf = models.FileField(upload_to='pdf')

#In urls.py:
urlpatterns += patterns('',
   (r'^media/(?P.*)$', 'django.views.static.serve',
{'document_root': '/Users/me/publications'}),
)

I think that's all the relevant stuff. Some findings/example tasks:

I upload a file, essay.pdf, using the Django Admin console.
http://127.0.0.1:8000/media/pdf/essay.pdf
#It works, there it is.

In the shell, (python manage.py shell):
>>>essay.pdf.path
u'/Users/me/publications/pdf/essay.pdf'
>>>essay.pdf.name
u'/Users/me/publications/pdf/essay.pdf'
>>>essay.pdf.url
u'/Users/me/publications/pdf/essay.pdf'

Now that doesn't seem quite right. I have seen working examples, I
even made one once, I don't know what is wrong here.

Thanks.

Exception in transaction block hidden by "InternalError: transaction aborted ..." exception

[Darren]

Hi

My app saves data in a method with "@transaction.commit_manually".

My code had a bug - a field in a model was the wrong datatype for what
was passed in, so I got a DataError exception back.

However, the only exception that was displayed to me was
"psycopg2.InternalError: current transaction is aborted, commands
ignored until end of transaction block".

I had to comment out "@transaction.commit_manually" in order to get
the real DataError exception to show.

My code looks like this:

@transaction.commit_manually
def save(self):
try:
# save data here
except BaseException as e:
traceback.print_exc()   # prints
psycopg2.InternalError traceback
transaction.rollback()
else:
transaction.commit()

I'm sure there's a way to get the original, DataError, exception...
can anyone help?

Thanks,
Darren

PIL & imagefield validation

[zayatzz]

Hello

On sunday i had problems with python when i installed stackless
python. Now i have compiled and installed :
setuptools & python-mysqldb and i got my django project up and running
again. (i also reinstalled django-1.1),
Then i compiled and installed, jpeg, freetyp2 and PIL. I also started
using mod_wsgi instead of mod_python.

But when uploading imagefield in form i  get validationerror:
Upload a valid image. The file you uploaded was either not an image or
a corrupted image.

Searchmonkey shows that it comes from field.py imagefield validation.
before raising this error it imports Image from PIL, opens file and
verfies it. I tried importing PIL from python prompt manually - it
worked just fine. Same with Image.open and Image.verify.

So what could by causing this problem?

Alan

What you have shown (with simplefix.json in your app's fixtures directory)
should be working.  How are you determining that it isn't?  Note there is no
feedback printed for non-initial-data fixtures loaded during testing, so you
won't see a message for simplefix.json as you do for the initial data
fixture.

If you are determining that it isn't working because your test code can't
access data that should have been loaded, then I'd suspect a typo in the
file name somewhere.  Unfortunately there is also no feedback for this case,
so double check that you've got the file with the right name, and specified
the right name in the TestCase fixtures attribute.

Admin site statics (CSS) seen via 'runserver' not via fcgi

[Gerard]

Hi All,

I'm trying to figure how to get the CSS to work on the /admin part of my
django project. Based on the same settings.py the /admin show correctly when
run with:

python ./manage.py runserver 192.168.1.72:8000

When I run it via fcgi like this:

python ./manage.py runfcgi host=192.168.1.72 port=8000 daemonize=false

It's a no-show. The last one runs behind a poperly working lighttpd/fgci
setup. I checked and indeed get a 404 on the .css files. I have been through
the docs several times in regards to ADMIN_MEDIA_PREFIX and MEDIA_URL but I
still seem to have a blind spot.

Since I am satisfied with the admin interface (and layout). I want to avoid
copying files from the "django/.../media" dir to my own static files project
dir.

Furthermore, the static files used in my own templates (like css,
javascript, images) work in both situations.

Would somebody be so kind to shine some light on my blind spot :)

Thanx a lot

Kind regards,

Gerard.

You can look at django-logging [1], it intergrates the python logging module 
with django as middleware.

Since this has come up several times in different threads recently...

No, those are not "errors". Errors would cause your application to
crash and dump a traceback on the screen. What you are seeing are
*warnings*, usually indicating that a bit of code is doing something
that's deprecated. In other words, Python is saying "hey, this will
work for now, but in future versions of Python it won't". The key
there being "this will work for now".

Staying clear on this distinction is of rather crucial importance,
since at this point there are quite a few things that will raise
deprecation *warnings* under Python 2.6, but which are not actually
errors and do not actually crash your application  -- they're merely
telling you that down the road in a future Python version it'll stop
working.

Not that I know of. Logging isn't really the realm of Django. Though
conversely it won't meddle with your logging functionality. You are free to
do what ever you would like to with your logging.

Re: Logging mechanism in Django

[Lokesh]

Hi,

I am trying to implement logging mechanism using Python library. But,
I am not sure on which mechanism/methodology used for Django
applications.

Is there any predefined process or methodology to be followed for
Django applications for logging mechanism.

Regards,
Lokesh

Using fixtures in tests

[Marek Wawrzyczek]

Hi,


I've got an application called myapp

In the main folder of django project there is initial_data.json file
containing initial data for the application
I also have file "simplefix.json" situated in myapp/fixtures
containing initial data for tests

Then after calling: python manage.py test myapp:

the following output is shown:

(...creating tables and indexes)

Installing json fixture 'initial_data' from absolute path.
Installed 114 object(s) from 1 fixture(s)
hello

myapp/tests.py has the following content:


from django.test import TestCase

class SimpleTestCase(TestCase):

fixtures = ['simplefix.json']

def testOne(self):
print 'hello'


How can I load database during tests from defined fixture? I tried
putting simplefix.json in myapp/ in main project folder, in fixtures
directory in main project folder and none of that worked

Regards,
Marek

 Are you using the Python logging library or are you trying to create your
own?

Re: Success at using "reusable apps"?

[Margie]

That's a good idea.  So you are suggesting, for example, that when the
threadedcomment gets saved, that my app catch the post save signal and
take its action then?  I like that idea, I'm going to play around with
that today.   I hadn't thought about using signals before, but I guess
that is the obvious solution to finding a way to do things in my own
code without messing with the "reusable" app.

Thanks for that suggestion!

Logging mechanism in Django

[Lokesh]

Hi,

I am trying to implement the logging (Code flow tracking) for my

I would like to store the log messages on daily basis for my

Need help or suggestions on how we can implement the logging mechanism
for an application.

I think you're approaching the problem incorrectly.  When dealing with
a relational database, go ahead and view things from a relational
perspective.  In this case, if you want your Person model to have
zero, one, or multiple Addresses, and a single Address can be used by
multiple people, what you want in Django is a ManyToMany field.  Yes,
this creates a couple more tables and the requisite joins, but as it
so happens, that likely won't be a problem for you, as you are writing
an application that is as you say "not made for National Post Office
domain."  In short, don't fight the relational model in this case.  It
is designed to handle such tasks.  The only reason you might want to
avoid an extra table or two is due to poor performance, but I suspect
that you are optimizing prematurely.  Until you have a large number of
users, you don't need to worry about one M2M field.  And your first
choices for optimization in Django should be caching and setting up a
separate image server, not database denormalization.

Django's ORM is a very powerful tool, and it makes the developer's
life a lot easier in many ways, but that in part is because the Django
developers made design choices that reflect best practices and channel
users in the proper direction.  The fact that Django does not make it
easy to do what you think you want is likely a sign that you are going
upstream against the natural flow of Django.  In short, take it as a
warning sign that you should rethink your approach.  Try working with
Address as a ManyToMany field, and see whether that works for your
application.  From there, if it presents a problem, you can always
rethink later, and you will have the benefit of knowing what problems
you need to work around.

Hope that helps,

---Peter

Re: send_mail function

[Gaarv1911]

For sending html I would rather do :

from django.core.mail import EmailMessage
from django.template import Context, loader

t = loader.get_template('email.html')
c = Context({'variable': variable,})
data = t.render(c)
msg = EmailMessage("subjet", data, "sen...@foo.com",
["recipi...@bar.com"])
msg.content_subtype = "html"
msg.send()

Make a template named email.html  and you can customize it with one or
more variables.

Re: Using custom table instead of "user" in django

[Jonas Obrist]

Here's what I did:

I took the built in auth system and changed it a bit, or to be more 
precise I changed all imports within auth (because I moved it within the 
pythonpath) and edited models.py:

http://dpaste.com/81651/

Whole code:

http://www.ojii.ch/auth.tar.gz

If you wanna use it:

Add the folder in the archive to your pythonpath.

Add 'auth' to your installed applications

Set 'USER_MODEL' in your settings file to the model you use (string).

Done.

NOTE: I did NOT test this yet!

Re: how do you display custom permissions on admin site?

[sam lee]

Ah thank you!
I was also putting permissions inside BaseModel.Meta.permissions
where BaseModel.Meta.abstract = True.
When I put permissions inside MyModel.Meta.permissions, it showed up
after flushing out and re-syncdb.

I guess I will repeat permissions for each derived model class.

Thank you again.

If you're using at least Django 1.1, you can use the empty tag:

http://docs.djangoproject.com/en/dev/ref/templates/builtins/#for-empty

For example:

{% for item in projects %}

   {% include projects.html %}

{% empty %}

   There are no items in the project.

{% endfor %}

Using custom table instead of "user" in django

[PlanetUnknown]

Guys,
I have a quick question. I am attracted to django due to its
flexibility however there is something bothering me now.
My question is can I use a custom table, say "consumer" instead of the
one provided my django ?
Here are the reasons -
1.) I have my whole DB model around this consumer table and want to
keep it.
2.) This table has a lot more fields than what the user has, which are
custom and uses the "email address" as the username.

I know no. 2 has a solution of using a custom backend, but there are
so many out there that they confuse me. Also,I don't want to use the
"admin" part of django since I'll have a custom app. for that, but
which works on "consumer"

I'm worried if I there is no way around using the django provided
"user" I'll have to re-invent the wheel, is that true ? e.g. session
management, etc. Not afraid of coding, but the whole reason I chose
django was to not do this.

Any direction by the Gurus is appreciated.

Re: Django-tinymce and filebrowser, error.

[Parthian]

Trevor,

I've had problems with the same combination of tools. For me Popup
windows are completely blank. But after adding document.domain as
below I could get the popups to work but only in Firefox and Safari (I
think).

Updated yourApp/yourMediaFiles/js/tinymce/tiny_mce_popup.js for
document.domain = 'yourdomain.com' to help with blank popup. Also same
in Templates/admin/base.html.  There is a post somewhere on the web
that explains the exact details which I cannot find. A search should
find it.

This may be irrelevant but worth a try and in any case try different
browsers to see if you get on better.

site and username unique together

[Fredde]

Hi!

I am working on a project with multiple sites and are using the
contrib.site app to separate them from eachother. The number of sites
will be high and changing often, so I don't want to modify the Apache
config and create a new VirtualHost/Location for each new site. I have
solved this by writing a middleware that parses the url and changes
the settings.SITE_ID based on that. Similar to 
http://www.djangosnippets.org/snippets/1099/

I'm planing to use contrib.auth for user login on each site, but I
want to make the username unique together with the site. I tried
something like this:

class SiteUser(User):
site = ForeignKey(Site)

class Meta:
unique_together = (('site', 'username'),)

But this will not work so well, since the username field has to be in
the same model as the unique_together meta attribute, and the username
field is still unique across the sites. So I tried to make the User
model abstract and removing the unique flag:

User._meta.abstract = True
User._meta.get_field('username')._unique = False

But now the ManyToMany fields in User will complain that it's a
abstract class, wich makes sence. And I guess you shouldn't modify en
existing model anyway. Is it possible to do what I am trying to do
without writing a new auth app? Are there any other problems with the
multi site approach?

class Person(models.Model):
home_adress = models.OneToOneField(Adress)
business_adress = models.OneToOneField(Adress)

Adress is like a Value Object, but I don't want any adress table, nor
extra foreign key and database joins. My application is not made for a
National Post Office domain. I just want an Adress class whitout
database identity.

Another possibility I know is define a custom Field Type, but this one
seems a too difficult solution for such a simple task. Especially if
Adress is made form simple and obvious attributes.

If Person has only one Adress attribute, the inheritance likes such a
good solution, but if I want a second Adress, or I want an Adress with
null=True, inheritance si bad.

Can you give me some suggestions, how to implement Eric Evans's Value
Objects in Django?

Create your own admin class for your extended User model, inheriting
from the one in contrib.auth.admin. Then unregister the default one
and register yours:

from django.contrib.auth.admin import UserAdmin

class MyUserAdmin(UserAdmin(UserAdmin):
    extended attributes here ...

try:
admin.site.unregister(User)
except except admin.sites.NotRegistered:
pass
admin.site.register(User, MyUserAdmin)

Re: how do you display custom permissions on admin site?

permissions are stored in db, syncdb doesn't alter existing tables, so
your permission will not  show up in your admin.

As the Fu..Funny Maunal say:

http://docs.djangoproject.com/en/dev/ref/django-admin/#syncdb

"Syncdb will not alter existing tables

syncdb will only create tables for models which have not yet been
installed. It will never issue ALTER TABLE statements to match changes
made to a model class after installation. Changes to model classes and
database schemas often involve some form of ambiguity and, in those
cases, Django would have to guess at the correct changes to make.
There is a risk that critical data would be lost in the process.

If you have made changes to a model and wish to alter the database
tables to match, use the sql command to display the new SQL structure
and compare that to your existing table schema to work out the
changes.
"

or.. you can try discarding the permission table and redo a syncdb,
but i can't assicure you that preexisting permissions assigned to
users will be conserved...

Re: Using glovar vars

[David Zhou]

For what you describe, you're not looking for "global" variables in
the sense that you want some value persisted in the same process.
You're looking at session variables, which are variables persisted for
a specific user session.

See:

http://docs.djangoproject.com/en/dev/topics/http/sessions/

Honestly though, the easiest way that I can think of is just to use
separate URLs.  That way, a user could easily use the PC version if he
desires.

Re: Using glovar vars

I`ve got an application developed for PCs and I want to make it
available for mobile devices. There are only some slight differences
between booth two versions, so I think is not worth while to develope
different applications. Instead, I've decided to develope an only
application in which I need a "global" variable that helps me to
remember if the user is using a mobile device or a PC (I know it on my
firts page, looking at the user agent). How can I store that
variable?? Of course, if different users connect to the application
they would have different user agents and thus, different values for
that "global" variable I want to use.
