2015-01-23 Thread Neto
Hi, I'm using login_required in url patterns but it does an error:

urls.py

from django.conf.urls import patterns, include, url
from django.contrib.auth.decorators import login_required


urlpatterns = patterns('',
url(r'^home/', login_required(include('home.urls'))),

)


error:
TypeError at /home/

'tuple' object is not callable

how to fix this?

Error when change a CharField to IntegerField

2014-12-30 Thread Neto
I changed a CharField to IntegerField and when I did ./manage.py migrate, 
appeared the message on terminal:

django.db.utils.ProgrammingError: column "rotulo" cannot be cast 
automatically to type integer HINT:  Specify a USING expression to perform 
the conversion.

What is it?

Re: Strange Bug

2016-04-22 Thread Neto
I discovered the problem, I have a post_delete for Action that creates a 
log, the problem is that this log is related to the Account, and it tries 
to create a log for an account being deleted, this was the conflict. 
Unfortunately Django does not say that the problem was in post_save.
Thank you, and Erick excuse my lack of kindness, I'm a little stressed.

Django apparently can't handle that error.

2016-04-23 Thread Neto
Hi, I am trying to delete an Account that delete in cascade others objects, 
but I have a post_delete in Car model that create a Log that have relation 
with this Account.
The django apparently can not handle the error. How to solve this?

Models:

class Account(models.Model):
pass


class Car(models.Model):
account = models.ForeignKey('Account', on_delete=models.CASCADE)


class Log(models.Model):
account = models.ForeignKey('Account', on_delete=models.CASCADE)


class CarLog(Log):
car = models.ForeignKey('Car', null=True, blank=True, 
on_delete=models.SET_NULL)


@receiver(post_delete, sender=Car):
def create_car_log(sender, instance, **kwargs):
try:
CarLog.objects.create(
account=instance.account,
)
except:
pass
 

Shell:


>>> account = Account.objects.create()
>>> car = Car.objects.create(account=account)
>>> CarLog.objects.create(account=account, car=car)
>>> account.delete()  # when delete car will try to create a log related 
with that account, but...

Error:

insert or update on table "myapp_log" violates foreign key constraint 
"myapp_log_account_id_6ea8d7a6_fk_myapp_account_id"
DETAIL:  Key (account_id)=(11) is not present in table "myapp_account".

It's happening this error rather than the exception.

Stephen, I am using Django 1.9.5, PostgreSQL 9.3
I do not know, maybe the order of the apps may be interfering in the way 
Django sorts the commands to be sent to the postgresql.

INSTALLED_APPS = [
'core',  # here: Account, Log
'myapp',  # here: Car, CarLog


What is happening is that post_delete is trying to create a log for an 
account that does not exist. The exception doesn't works.
This seems to be a bug.

Re: Django apparently can't handle that error.

The right is just Account.objects.last().delete() to delete everything 
related to account.
My project has many models related to account, and everything has log, is 
unfeasible be deleting the rows of each model to the end delete the account.
Django needs to handle it.

(Is it a bug?) TruncMonth does not work when there is "ordering" in the model Meta (Django 1.10)

2016-08-10 Thread Neto
I'm trying to get number of records per month, but Django does not return 
correctly when there is "ordering" in class Meta Model.

I have the Abc model, with 4 records made this month, look what happens 
(Django 1.10, PostgreSQL):

class Abc(Base):

class Meta:
ordering = ['-date_pub']


>>> Abc.objects.annotate(month=TruncMonth('created_at')).values('month').
annotate(total=Count('id')).values('total')


Without "ordering"

class Abc(Base):
pass


>>> Abc.objects.annotate(month=TruncMonth('created_at')).values('month').
annotate(total=Count('id')).values('total')


Why this happens? Is it a bug?

It is a good practice to add or edit an object in the same view?

2015-08-10 Thread Neto
Hi, It is a good practice to add or edit an object in the same view or is 
it better to separate?

*For example:*

def add_edit(request, id=None):
form = MyForm(request.POST or None)
if request.method == 'POST':
if form.is_valid():
form.save()
return HttpResponse('success')
render(request, 'add_edit.html', locals())

EMAIL_BACKEND doesn't works with Amazon SES!?

2016-03-28 Thread Neto
I'm trying to send emails with Amazon SES, but when I use default 
EMAIL_BACKEND raise error:

Config:

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' # this is 
default
EMAIL_HOST = 'email-smtp...amazonaws.com'
EMAIL_PORT = 465
EMAIL_HOST_USER = '...'
EMAIL_HOST_PASSWORD = '...'
EMAIL_USE_TLS = True

Error:

raise SMTPServerDisconnected("Connection unexpectedly closed")
smtplib.SMTPServerDisconnected: Connection unexpectedly closed

If I use:
  
EMAIL_BACKEND = 'django_smtp_ssl.SSLEmailBackend'

from https://github.com/bancek/django-smtp-ssl, works right.

Code of this backend:

import smtplib
 
from django.core.mail.utils import DNS_NAME
from django.core.mail.backends.smtp import EmailBackend
 
class SSLEmailBackend(EmailBackend):
  def open(self):
if self.connection:
  return False
try:
  self.connection = smtplib.SMTP_SSL(self.host, self.port, 
local_hostname=DNS_NAME.get_fqdn())
  if self.username and self.password:
self.connection.login(self.username, self.password)
  return True
except:
  if not self.fail_silently:
raise

What the problem with default EMAIL_BACKEND? Why I can't use him?

Re: Problem with static in Django 1.5 virtualenv

2013-08-02 Thread Mário Neto
Suggestion:

*Install Unipath with a:*
$ pip install Unipath

*and in settings file:*
from unipath import Path
PROJECT_DIR = Path(__file__).parent

STATIC_ROOT = PROJECT_DIR.child('static')

*Try in urls.py*

from django.conf.urls.static import static
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
...
some imports
...

urlpatterns = patterns('',
...
some urls
...
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

urlpatterns += staticfiles_urlpatterns()

Good luck!

Re: Static files

Re: Noob question: using multiple classes in a detail page's view

2010-12-21 Thread Mário Neto
For that you could use the method select_related, if you want the details
page has executives related to the nonprofit:

e = Executive.objects.select_related().get(pk=id)

Thus, there is a performance gain, it does not require database queries.

multiple settings.py

2012-03-03 Thread João Dias de Carvalho Neto
Hi

I'm recently diving into Django framework and a doubt is flashing my head.

If I want to develop and to deploy cloud web applications, each customer 
will have your singular database. In the Django approach, The database 
configurations are in the settings.py file. How can I do to separate a 
settings.py file for each customer, and their unique configurations without 
create a copy of my entire project?

It's possible to create dinamically a settings.py file at user session or 
it's better keep those files existing at web root?

Any help will be apreciated?

Thanks in advance

João Dias de Carvalho Neto

ManyToManyField using specific database

2015-06-23 Thread João Dias de Carvalho Neto
Hi all,

I have an application with Django with database routers. Basically I got 
the request path, split it to get subdomain name and set the database by 
this way.

I do not use default database, so I do not migrate it.

This route action It's working very well but I am still facing trouble when 
I am using post_migration signals with post_migrate signal callbacks. 

My custom command to something like above:

def define_groups_auth(sender, **kwargs):
admin = Group()
admin.name = "Administrator"
admin.save(using=kwargs['using'])

perm = 
Permission.objects.using(kwargs['using']).get(codename='my_permission')
admin.permissions.add(perm)

post_migrate.connect(define_groups_auth,
 sender=apps.get_app_config('my_application'))

When I execute ./manage.py --database=db1 for example a strange behavior 
occurs.

The Group Administrator is created but the permission tries to be added on 
default database instead db1 database.

hacking the "add" method i discover that it do not contains a "using" 
parameter. 

Does someone knows a work around to save this ManyToMany relation correctly 
on post_migrate signals?

Re: dear django users & fans.. i really need ur help ok

2017-01-21 Thread José Florencio de Queiroz Neto
Dear friend,
First of all, welcome to the Django community. 
I recommend you to complete the Django tutorial 
(https://docs.djangoproject.com/en/1.10/intro/tutorial01/).
If you have time, buy and complete the book Django Unleashed 
(https://django-unleashed.com/).
Good luck,
Florencio
