Getting Timezone conversion in template with USE_TZ = False;

[Lee Hinde]

I'm displaying a date/time field in template.

Data in the database: 2013-05-30 00:00:00
template tag:   {{ reg.registration_date  }}
as displayed in the web page: May 29, 2013, 5 p.m.

I didn't have a USE_TZ setting until I tried to figure out what was
happening here.

The data I'm playing with now was all migrated from another system directly
to the backend, i.e., I didn't migrate through django.

Creating an "Edit Page"

[Liz]

I've been struggling in creating an edit page and I need help, please!

The goal is to get the user to search a record and when they click on the 
link, I would like to use form.p with the values it finds from the 
database. 

For example if they search a name and click on the person that is already 
stored in the database, they should be redirected to a page where it shows 
a form with the person's information and the user should be able to edit 
and save the changes. 

I would appreciate any time of help to accomplish this. 

I've been thinking to do the following but I do not believe I'm on the 
right track:

 
*html page*
 

{{form.as_p}}




*view*
*
*
  def person(request, person_id=1):   
   return render_to_response('edit.html', 
  {'article': Data.objects.get(id=person_id) })

Re: broken packages

[Aaron C. de Bruyn]

This isn't a django issue, but rather an issue with the package management
system in your Linux distribution.

This can happen if someone publishes a broken package, or you add on PPA's
that have conflicting requirements.

Basically it's saying that geonode depends on a version of Django greater
than 1.5.1 but version 1.4.1 is installed.  It may be that 1.5.1 is not
available in your distro yet.

You might try the Debian or Ubuntu forums for further assistance.

Re: Django: Temporary "wait page" while heavy compute processing is handled

[François Schiettecatte]

Hi

Another option is to email something with a link to a page where they can pick 
up their job results, you could easily generate a one-time token which can be 
inserted into a table and in the email as part of a url.

You could even you the same table as your job queue, rows missing their tokens 
still need to be processed, and you can check the url against the tokens for 
validity.

Finally you could also age out old rows at which point the tokens would be 
invalid.

Re: How can I order my list based on a field in a different table?

[Pepsodent Cola]

Thank you Eric for the pointers!

But I think Django is complaining about me having too many Relationships in 
table Altword, or perhaps I have typed syntax wrong and missunderstand the 
error message?

Exception Value: 

 has more than 1 ForeignKey to 



#___

class Word(models.Model):
rosword = models.CharField(max_length=200)
direct_transl_word = models.CharField(max_length=120, blank=True, 
null=True)
pub_date = models.DateTimeField('date published')

def __unicode__(self):
return self.rosword
#___

class Altword(models.Model):
#class Altword(Word):
rosword = models.*ForeignKey*(Word)
alt_ros_word = models.CharField(max_length=200)
alt_transl_word = models.CharField(max_length=200)
articulate = models.CharField(max_length=200)
wordy = models.*OneToOneField*(Word, related_name='altword_wordy', 
primary_key=True)
votes = models.IntegerField(default=0)
pub_date = models.DateTimeField('date published')

def __unicode__(self):
return self.alt_ros_word
#___



First I tried to follow this example but then above error showed up:
https://docs.djangoproject.com/en/1.5/topics/db/examples/one_to_one/


Second time I tried this but I couldn't make it work:
http://catherinetenajeros.blogspot.se/2013/04/django-error-one-or-more-models-did-not.html

Third time I tried to play with "Multi-table inheritance".  But it only 
lead to Django complaining about duplicate fields which suggested that I 
needed to change field names in several files.  I didn't go down that path. 
 And it seemed "Multi-table inheritance" also complained about my first 
error message about having too many relationships in Altword table.
https://docs.djangoproject.com/en/1.0/topics/db/models/#id7


How should I proceed in order to find the solution to this problem?

Re: problem with deploying django using mod wsgi

It may be looking in html because it isn't getting the definition from the 
view method or class, so it's going with the default.
Try importing everything in views:

Re: Django: Temporary "wait page" while heavy compute processing is handled

[Nick Santos]

Hi Howard,

You will want to look into Celery , which lets
you do heavy processing outside of your web requests. You can then use some
checking via Javascript to see if the work is done yet and load a new page,
or ask the user to come back later. There's a celery "app" for django that
makes certain tasks a little easier. Sorry I can't provide more details
than pointing you there right now, but I hope that helps. Someone on this
list may have some better options for you that involve less setup, but
Celery is the first thing that came to mind for me.

Also, just as an FYI, your links won't work because they point to your
local development server and can't be accessed by anyone else.

Hi Howard,

I'm not very experience with django yet, but if you are not very familiar

with Ajax, that's why I work with it, I find it more friendly, and get the

I hope someone can give you a better django approach, but I think the clean

Custom auth backend and importing custom user model

[Rok Jaklič]

Hi,

I wrote custom auth backend, however when I try to import custom user model 
I get an error like:
ImportError: cannot import name "CustomUser" 

even though I have in custom_auth.py from users.models import CustomUser.

I found out that custom_auth.py is called before custom models.

Any ideas how could I solve this problem?

Kind regards,

Rok

Re: Error: ImportError: No module named south

[Tito Gonzales]

before installing psycopg2 you have to install Postgres, you did it right? 
To test the south use the sqlite3 first then switch to Postgres

Incrementing the slug by avoiding Integrity error in django models save method

[shiva krishna]

I have a model with two fields as below

**models.py**

class Publisher(models.Model):
name = models.CharField(max_length=200)
slug = models.SlugField(max_length=150, unique=True)

def save(self, *args, **kwargs):
if not self.id and not self.slug:
slug = slugify(self.name)
try:
slug_exits = Publisher.objects.get(slug=slug)
if slug_exits:
self.slug = slug + '_1'
except Publisher.DoesNotExist:
self.slug = slug
super(Publisher, self).save(*args, **kwargs)

Here i am creating a slug based on the `name` field as we can see above

So when we try to create a publisher with `name already exists`, the `save` 
method of the model will add the `_1` to the end.

And when we again try to create a new record with same `name`, an 
`Integrity` error will be raised as below

>> Publisher.objects.create(name="abc")
   result: slug will be "abc"
>> Publisher.objects.create(name="abc")
   result: slug will be "abc_1"
>> Publisher.objects.create(name="abc")
   result: 

 .
 .
 34 del cursor
 35 del connection
---> 36 raise errorclass, errorvalue
 37 
 38 re_numeric_part = re.compile(r"^(\d+)")

IntegrityError: (1062, "Duplicate entry 'abc_1' for key 'slug'")

So what i am want is if the title/slug already exists in the database and 
if slug contains number in it(at the end like abc`_1`), we should increment 
it that number

So what all i want is to `increment the number in the slug`  as below if 
the title/slug already exists in the database

abc
abc_1
abc_2
abc_3  

So can anyone please let me know how to implement the above logic of 
incrementing the slug ?

Thanks in advance..

Django: Temporary "wait page" while heavy compute processing is handled

[Howard S]

Hi everyone,

I have a page whose content cannot be loaded until a lot of computations 
are done, which may take a minute or two. How can I set up a temporary 
"wait page" that will direct users to a new link once the computing is done?

For example:
User submits an input: http://127.0.0.1:8000/tools/submit/ 
User waits for output: http://127.0.0.1:8000/tools/WaitPlease/
User receives the output: http://127.0.0.1:8000/tools/result/

If such redirect is a bad practice, can should i do this via AJAX (which I 
am not very familiar with)?

Please and thank you.

Best,
Howard

Re: django windows user

[Robin Lery]

Thank you all! Just one more question though, does hosting provider
provides any interface like virtual machine or so? It would have been great
if they were.

Re: ImportError: No module named 'exceptions' - Python3

Hi Folks,

 I ported my project from python2.7 to python3 using 2to3 module.
One of my class is inherited from Exception class, but after porting to
python3 i am getting *No module named 'exceptions' *error.

 My class looks something like this :-



Try it without importing Exception. Looking at django.core.exceptions it 
seems specifically importing Exception is not required.



*from exceptions import Exception*
*class A(Exception):*
*def __init__(self, value=None):*
*self.value = value*
*
*
And the error which I am getting is
*
*
Traceback (most recent call last):
   File "", line 1, in 
ImportError: No module named 'exceptions'


I tried to import exceptions in python3 shell but there also I am
getting same error.
Is there any problem with my code or did I missed something while
porting or python3 itself has some problem while importing exceptions ?


Thanks and Regards.
Abhijeet Shete

Re: ImportError: No module named 'exceptions' - Python3

[Jani Tiainen]

Hi,

In Python 3 exceptions module was removed and all standard exceptions were 
moved to builtin module. Thus meaning that there is no more need to do explicit 
import of any standard exceptions.
