Re: problem with using suds and sharepoint

[James Schneider]

Based on this:

http://schemas.microsoft.com/sharepoint/soap/>schemas.microsoft.com
/sharepoint/soap/
">Item does not exist. It
may have been deleted by another user.

I'm guessing that listItemID number 2 doesn't exist, or the ID of the
parent object isn't specified. I'm not familiar with the WSDL for
SharePoint, but you are referencing an object that currently doesn't exist.

BTW, are you using the suds or suds-jurko version? I would highly recommend
the Jurko version, the original is a bit crusty...should be almost a
drop-in replacement.

Re: ModelAdmin with inlines: How to learn if/what has changed before the models are saved?

[Collin Anderson]

Hi Carsten,

save_model() happens first, then save_related() which calls save_formset() 
on each formset.

It might end up being easier to save the parent model _again_, instead of 
doing something before it's saved.

_has_changed() / has_changed() may come in handy in your case.

Re: change_list html template filter block inject a css class

[Collin Anderson]

Hi,

In your custom(?) filter, you could try wrapping your text in , and then in mark_safe(), though be careful with that, 
security-wise.

Honestly, it might be simplest to use Javascript to apply a special class 
after the fact.

Re: CSRF Failing after server upgrade.

[Collin Anderson]

Hi Ed,

Did you figure it out?

Is your login page getting cached? The CSRF token is re-generated after a 
successful login, so if you click "login" twice or hit back after a 
successful login, it won't work.

Do you happen to know, specifically, which django versions you upgraded 
from/to?

Yes, this is expected. Django's form system is designed for use with
HTML forms, which do not provide partial data: unchanged field values
are sent too, so this problem does not occur.

That in itself wouldn't prevent switching to the behavior you want,
except that it is not compatible with how checkboxes are handled in HTML
forms. If a checkbox is unchecked, the browser will not send that
checkbox's name in the submitted POST data at all. So with the behavior
you're asking for, it would be impossible to ever change a boolean field
represented by a checkbox from True to False, using an HTML form.

Model form with optional fields issue

[marcin . j . nowak]

Hello!

I have model form defined with all optional fields (required=False).
I want use this form to update only provided fields leaving others 
unchanged.
But Django replaces optional fields to empty values and removes data from 
models.


A short example:

class MyForm(forms.ModelForm):
class Meta:
model = User
fields = ('username', 'email')

def __init__(self, *args, **kw):
super(MyForm, self).__init__(*args, **kw)
for field in self.fields.values():
field.required = False


In [21]: admin = User.objects.get(username='admin')

*In [22]: admin.email*
*Out[22]: u'ad...@example.com'*

In [23]: form = MyForm(data={'username': 'admin'}, instance=admin)

In [24]: form.is_valid()
Out[24]: True

In [25]: form.save()
Out[25]: 

In [26]: admin = User.objects.get(username='admin')

*In [27]: admin.email*
*Out[27]: u''*

In my opinion this is big, fat, ugly bug or a design misconception.  
If something is not provided does not mean that someting does not exist!
Django should skip updating these unprovided fields by removig them from 
cleaned_data dict. 

You can even try to save this form without data (ok with data, but with 
unknown keys):

form = MyForm(data={'unknownfield': 'some-value'}, instance=admin)
form.is_valid()

# form.cleaned_data has empty strings

form.save()


Username and email will be replaced with empty strings. 
Where is admin?, you'll ask... And you'll hear a strange voice - "admin is 
cooking borscht with ravioli, dude!"

What do you think - is this expected?

Revisiting the case-sensitive login for the default user manager

[Roman Onosovski]

Hello fellow Djangoers, I am new to the framework and just recently built a 
site using it.
However I was not aware of the username hurdle until just recently.
I did some research and found that I can make my own user manager and etc.

Now this is probably a bit of a hack, but tell me what you think.

I am on 1.6.5 and I did this: 

from:

def get_by_natural_key(self, username):
return self.get(**{self.model.USERNAME_FIELD: username})

to:

def get_by_natural_key(self, username):
return self.get(username__iexact=username)

It works and does what I need it to do. How illegal is this and what 
potential problems can this create that I may not see now?

Thanks guys

Just to wrap this up, I wrote a function to get all or some cache entries. Most 
of the code is copy-paste from django.core.cache.backends.db.


def get_cache_entries(key_prefix=None):
db = router.db_for_read(cache.cache_model_class)
table = connections[db].ops.quote_name(cache._table)
with connections[db].cursor() as cursor:
sql = "SELECT cache_key, value FROM %s" % table
params = None
if key_prefix:
sql += " WHERE cache_key LIKE %s"
params = (key_prefix + '%',)
cursor.execute(sql, params=params)
rows = cursor.fetchall()
res = {}
for row in rows:
value = connections[db].ops.process_clob(row[1])
res[row[0]] = pickle.loads(base64.b64decode(force_bytes(value)))
return res

Re: Database queries location

[aRkadeFR]

Depend exactly on what to compute for your post data.

I would almost write no logic code in the views.

I split every application as follow:
- managers.py: All the logic as a table level (raw SQL, complex queries)
- models.py: All logic as a row level / object level (python computing data)
- forms.py: All logic as forms data / processing / validation for 
request data


Have a good one,

Re: Select a single field from database (postgresql)

[aRkadeFR]

Hello Cássio,

You first need to map your cars table with a Model in Django
(https://docs.djangoproject.com/en/1.7/topics/db/models/),
then you can construct your query something like this:

Car.objects.order_by('-registered').last()

Check out the documentation on queries here:
https://docs.djangoproject.com/en/1.7/topics/db/queries/

Have a good one,

Re: Can't open manage.py

[Guilherme Leal]

Are you sure that your shell is running on the same folder that contains
the manage.py?
