Re: Django queryset result and mysql query are wrong after updating from 3.0.2 to 3.0.3

[Ricardo H]

Hi Simon, 

It was ok on 2.2.6, only on 3.0.3 it fails.

I use BigIntegerField because I use it for some calculations after that, 
but even if I try with DurationField it doens't assert right.

Definitely must be caused by this patch, if I can't find another solution, 
where and how should I report this ?.

Thanks.

Django queryset result and mysql query are wrong after updating from 3.0.2 to 3.0.3

[Ricardo H]

Hello,  after I updated django from 3.0.2 to 3.0.3 the result of the 
following code has changed when using a MySQL database. It produces a wrong 
sql query and also the wrong result for "*end_total_time"* attribute.
Is this a bug ? also is there any other way to get the wright result using 
3.0.3 ?

Thank you.

# When I use base_date to do the end_total_time math in 3.0.3 
together
# with ended_at annotated, it creates a wrong query
qs = self.annotate(

RE: Trying to filter out choices in a form based on the logged in user.

[Ricardo Cataldi]

Hello there Galvin,

 

You can create properties on the users and filter the queryset conditioning to 
the user. It depends on how many categories of user you have and how these 
users are supposed to be filtered by those teams.

 

For example, if you have a spatial selection based on user location, you create 
a property called ‘location_filter’ and set the separation rule on this 
property, like:

 

@property

def location_filter(self):

location = self.location

filter_rule = 5miles

return [self.location - filter_rule, self.location + 
filter_rule]

 

and in your form you set a init argument to query those filter rules, in the 
fashion that you want:

 

def __init__(self, *args, **kwargs):

user = kwargs.pop(‘user’, None)

self.fields[‘club_id’].queryset = 
Club.objects.filter(place__lte=user.location_filter[1], 
place__gte=user.location_filter[0])

 

I have not tested this solution, but with some minor code changes it should 
work like a charm in filtering the club queryset.

Hi all,

 

If anyone could help or point me in the direction of some documentation for the 
below problem I am having I would really appreciate it.

 

Just to explain quickly:

1.  I have a model called "Team" which contains a foreign key to another 
model called "Club"
2.  The "Club" model contains a foreign key to the "User" model.
3.  I have a form for the "Team" model which takes in "club_id", currently 
it lists all the club_id for all users and I want to restrict this.
4.  I am looking to find out how I can auto-populate this field "club_id" 
based on the logged in user, which I will then hide in the form. 

Below is my forms.py

 

class ClubInfoForm(forms.ModelForm):
club_address2 = forms.CharField(required=False)
club_address3 = forms.CharField(required=False)

class Meta():
model = ClubInfo
fields = ('club_name', 'club_logo', 'club_address1', 'club_address2',
  'club_address3', 'club_town', 'club_county', 'club_country',)

def clean_club_name(self):
club_name = self.cleaned_data['club_name']
if ClubInfo.objects.filter(club_name=club_name).exists():
raise ValidationError(_("Club already exists"))
return club_name


class TeamForm(forms.ModelForm):

class Meta():
model = Team
fields = ('club_id', 'team_name', 'manager_name')

class ClubInfo(models.Model):

user = models.OneToOneField(User, on_delete=models.CASCADE)
club_name = models.CharField(max_length=50, default='', unique=True)
club_logo = models.ImageField(upload_to='profile_pics', blank=True)

Loading Django views inside template with JQuery

[Ricardo Cataldi]

Hy guys, you all right?

I have a problem that it seems not to be any answer in Stack Overflow.

I need to load three views inside a template, and i decided to do that 
based on html tags and JQuery. The bellow image shows how the front end 
will look like:

[image: imagem_tab.png]

What happens is that the tabs should load a view separately, I've searched 
on ways of doing that with JQuery but i didn't found any that would work...

Can anyone tell me how exactly I can load a view with JQuery inside a html 
tab? In case it is not possible, can you give me an alternative?

The html following:

{% block header %}


{% trans "Gerenciamento de 
Produtos" %}




list
Listar Produtos




view_list
Listar Opções




add_box
Adicionar Opções






{% endblock header %}

{% block content %}





{% block productlist %}

{% endblock %}










{% block listtoptions %}

{% endblock %}










{% block createoptions %}

{% endblock %}





{% endblock content %}


I want to load the views inside all those blocks.

Thanks in advance!!

First you can install python tools and other librarys

If you using Ubuntu or Debian, check this steps

sudo apt-get install python-setuptools apache2 libapache2-mod-wsgi

sudo apt-get install python-pip

sudo apt-get install *python-dev libmysqlclient-dev*

Don't use
 'ENGINE': 'mysql.connector.django',

USE

quasi-distributed system sharing data in django

[Ricardo Pascal]

Hello folks,

I have two django projects, (let call them A and B) they are independent
applications (with different django versions), I'm in need to sync some
data/models from A to B.

My plan is to use the post_save signal to start a celery task that will
post a subset of data from A to B using the B API.

This new data will be stored in models at B and be used in relationships
with data in B. (To make things easier, those data will never(probably) be
created or updated from B application)

I'm seeing the necessity to keep the primary key on both
applications synchronized too.

My questions is: should I keep using the auto-increment id from django, or
instead use some uuid as pk?

Also, any better idea on how to implement this? Tips, unforeseen problems
or any rant about that matter will be appreciated.

Thanks in advance,

--
Att.

Re: how to upload file with pjango

[Ricardo Daniel Quiroga]

I suggest redefining the form

class UploadFileForm(forms.Form):
title = forms.CharField(max_length=50)
file2 = forms.FileField()
MAX_FILE_SIZE = forms.CharField(widget=forms.HiddenInput(), initial =
1)


and in template upload.html you tried this?


 Title  {{ form.title }} 
Choose a file to upload: {{ form.file2 }} 
{{ form.MAX_FILE_SIZE }}

Re: How to access selected options from a select list to show them in a table ?

[Ricardo Daniel Quiroga]

Hello,
What you must do is to use Javascript and AJAX, to have the desired
behavior, I guess would be for onchange event. By the way it is therefore
desirable to handle the tables in the following format

CKEditor

Buenas.

Estoy usando ckeditor en django. 
Todo bien, lo instalé bien y por parte del admin funciona excelente.

Lo que quiero es llevar esa herramienta a un form. Crear un formulario que 
contenga ckeditor.

Espero me entiendan y puedan ayudarme, ya que, he intentado de muchas 
formas y nada me resulta.

Muchas gracias!
Saludos.

Hello, i have some issues that is occured while i was installing Django on my 
Windows 10.
I'm new in using Django framework and also python on windows.




To the article:





Install Python




I installed python as it was said:


Downloaded python 3.5.1 for windows.

Installed using option: create system variable.

Checked version.



Install virtualenv and virtualenvwrapper¶




Then i tried to instal virtualenv and virtualenvwrapper as it is said:

pip install virtualenvwrapper-winbut the command freezes (or hangs) widows 
command prompt.After some search i found "python -m pip install virtualenv" and 
"python -m pip install virtualenvwrapper" that worked well.And now i'm 
stuck.mkvirtualenv myproject is not working.As i investigated: mkvirtualenv is 
a batch file, that executes virtualenv.exe in python's Script folder.This 
executable file hangs my command prompt, every time i type mkvirtualenv 
myproject or executing "virtualenv.exe myproject" directly.I don't know what to 
do, but what i do know - those pip.exe, virtualenv.exe and other .exe files in 
%PYTHONHOME%\Scripts are hanging my commandprompt.If Anyone has any ideas with 
my problem, please help me.

Re: update() on queryset django 1.7.1 not functional

[Ricardo L. Dani]

Hello Biola,

When you do a update in a queryset, the objects of the Session that already
instantiated need to be updated.
If you do in your test:
self.assertEqual(Session.objects.get(id=result.id).price, Decimal('700'))
The assertion will be ok

Different user login after session was closed redirects to previous user last page

[Ricardo Tubio-Pardavila]

 

 
  
I am currently developing a Django website and I am using 
django.contrib.auth and django-security-session for closing user sessions 
automatically. 

In case a user leaves its session open and a new user arrives at the same 
navigator after that session expired, if the new user attempts to use that 
same session, the session will be automatically closed. However, if now 
this new user logs in again, he is redirected to the last page where the 
previous user was.

I have taken a look at the code from django-security-session and I found 
the following at middleware.py "process_request":

from django.contrib.auth import logout...def process_request(self, 
request):
...
delta = now - get_last_activity(request.session)
if delta.seconds >= EXPIRE_AFTER:
logout(request)
...

So it seems that django-security-session relies on django.contrib.auth for 
closing the session. This logout flushes the current session and removes 
user id's from the request. However, the current page for the user that has 
just being logged out is still preserved for redirection after the 
following login. This login, in my case, is performed by the decorator 
@login_required, which relies on method 
"django.contrib.auth.views.redirect_to_login":

def redirect_to_login(next, login_url=None, \
redirect_field_name=REDIRECT_FIELD_NAME):
...
resolved_url = resolve_url(login_url or settings.LOGIN_URL)
login_url_parts = list(urlparse(resolved_url))
if redirect_field_name:

querystring = QueryDict(login_url_parts[4], mutable=True)
*querystring**[redirect_field_name] =** next*
login_url_parts[4] = querystring.urlencode(safe='/')

   return HttpResponseRedirect(urlunparse(login_url_parts))

... where the page for redirection is generated utilizing the url from the 
last user that is already logged out and that might not be the same as the 
one that is logging in right now.

Before starting patching and freaking out around the code, is there 
anything I am missing? Is there anyway in which I can instruct 
django.contrib.auth not to do this and, in case a different user logs in, 
just redirect the new user to its home page?

Re: Does not generate the password hash my User

[Ricardo]

Hi Thomas.
Even entering rende_value = False does not. The password keeps popping up 
as text.
did not quite understand how that password1 is inserted before the check 
password2.
I could not see this problem.

Does not generate the password hash my User

[Ricardo Kamada]

I have a model "Cliente" and in it a field "password".
In forms.py file, I am using ModelForm, but put in the password field
Password = forms.CharField (widget = forms.PasswordInput (render_value =
True))
It turns out that the admin password field appears readable, and I do not
want that to happen.
I tried to put in set_password. Models but did not succeed.
Now if I put in the admin:
form = FormCliente
Displays the password field and confirm password type password.
But I will not so I want to appear only the password hash.

http://pastebin.com/AQnWR0W3

Re: clicking the list_display link open a new page with the result of my queryset

[Ricardo]

Hi
the file full url like this
http://pastebin.com/ztF8VDET
I just try to pass the id as said but still did not work.
the error is this
NoReverseMatch at / admin / event / incricaoevento /
Reverse for 'evento.views.lista' with arguments '(1)' and keyword arguments 
'{}' not found.

Now I do not know if you're calling the view correctly, if the error is in 
reverse ("evento.views.lista", args = [self.evento.id]) or something that 
gotta do with get_url the admin.

Re: Call method of the session template

[Ricardo Kamada]

I understand what you say, however I know only call methods using {% url
'app.view.func'%} or {%}% app.view.func.
As I understand this django-aap carton, the shopping cart in the session
live. If it is in session I would have
access their methods and attributes. Well that's exactly what I'm not
getting. Access method remove_single.
In this href = "" is an image that removes the items you want to call the
method remove_simgle.
Actually I'm wrong in doing {% url%} because I do not want move pages. I
just want to remove the item from the cart.


class Cart(object):
"""
A cart that lives in the session.
"""
#...
#...

def remove_single(self, product):
"""
Removes a single product by decreasing the quantity.
"""
if product not in self.products:
return
if self._items_dict[product.pk].quantity <= 1:
# There's only 1 product left so we drop it
del self._items_dict[product.pk]
else:
self._items_dict[product.pk].quantity -= 1
self.session.modified = True

Re: Django-cart. How to run method add_to_cart?

[Ricardo Kamada]

Leonardo Hi thanks for the reply but I still can not understand.
I really need to pass the id and quantity parameters in the url? After all
I'm recording the items in the correct session?
I saw that the method has no return add_to_cart, as well as other methods
remove_from_cart.
In my template I am calling the method like this:
  Buy  

and URLs:
url (r '^ products / buy / $', 'cart.views.add_to_cart', name =
'add_to_cart')

You say that to pass arguments id and quantity that url?

Ricardo

Re: Missing files on a new project

[Ricardo Diaz]

Well, i'm following a video tutorial -> this guy is using Django 1.4 and 
when he uses startmanager on shell Django creates all of those files on the 
main folder.

Check it about 3:11 https://www.youtube.com/watch?v=fVNL5MwskiQ

That is the reason why I'm asking for help.

Missing files on a new project

[Ricardo Diaz]

Hi, I'm pretty noob with Django.

I've readed a few pages of the Django-book and just started to create my 
own projects.

When I try to create a new project using django-admin startproject demo, it 
just creates 2 things

project
  l--demo
  l--manage.py

I don't know why it doesn't create the missing files: __init__.py 
settings.py and urls.py

I'm working on Ubuntu 12.04 and this happens on Django 1.4.3 and 1.4 
versions

Thx for your help.

[Ricardo Grizonic]

Hey everyone,

I recently upgraded from Django 1.3 to 1.4.1 and now it seems that for 
every new thread, a new database connection to postgresql is created. I'm 
using:

from django.db import connection

which, according to the docs, should get a global connection that would be 
used by all the threads. Anything I might be doing wrong?

Thanks, in advance, for you help!

Re: Difficulties using generic views (Tutorial 4, Django 1.4)

[Ricardo Cardoso]

Oddly, when i started up the server this morning i could now see the polls 
correctly, while not having changed my code, by accessing 
http://127.0.0.1:8000/polls. Don't know if Django is prone to such 
randomness but am happy that it works now. Tested everything, added a view 
so that http://127.0.0.1:8000 loads polls, voted and viewed results. All 
fine.

I'll carry on testing this and getting a couple more tutorials done before 
moving to my first django production.

Thank you for your time and patience Carlos, much appreciated.

Re: Difficulties using generic views (Tutorial 4, Django 1.4)

[Ricardo Cardoso]

Thank you for your input guys. 

Sadly, i had already checked it Carlos and have my templates for polls 
under:
/home/my_user/Webdev/Templates/polls

In this case my template dir is set up as:
/home/my_user/Webdev/Templates/

Should i create another polls dir under templates 
(/home/my_user/Webdev/Templates/polls/polls) considering in the error 
message i get 'polls/poll_list.html' , besides 'index.html'? This seems 
redundant and i'd like to understand why i would have to. 

Thanks again for your help.

Difficulties using generic views (Tutorial 4, Django 1.4)

[Ricardo Cardoso]

I'm new to django and python, and decided to follow up the available 
tutorials to get up to speed. These were helpful and got me on my feet but 
while finishing up the tutorial i hit a major snag. While everything was 
working properly using custom views, i can't seem to make my app load the 
correct templates after switching to generic views.

Here's the code:

#urls.py
from django.conf.urls import patterns, include, url
from django.views.generic import DetailView, ListView
from polls.models import Poll

urlpatterns = patterns('',
url(r'^$',
ListView.as_view(
queryset=Poll.objects.order_by('-pub_date')[:5],
context_object_name='latest_poll_list',
template_name='polls/index.html')),
url(r'^(?P\d+)/$',
DetailView.as_view(
model=Poll,
template_name='polls/detail.html')),
url(r'^(?P\d+)/results/$',
DetailView.as_view(
model=Poll,
template_name='polls/results.html'),
name='poll_results'),
url(r'^(?P\d+)/vote/$', 'polls.views.vote'),
)

The way i decided (perhaps wrongly) to organize my apps and templates is as 
follows:

Template dir as defined in settings.py:
TEMPLATE_DIRS = ('/home/my_user/Webdev/Templates/', # this is where i'm 
storing my templates at the moment

App location: /home/my_user/Webdev/Django-lessons/pollproject/polls

If i try to access the polls app directly by using the URL: 
http://127.0.0.1:8000/polls/ i now get an error message stating that:

TemplateDoesNotExist at /polls/ 

index.html, polls/poll_list.html



I realize this might have something to do with where i decided to store my 
templates (made more sense at the time to store them separately since i 
thought i could use different templates for the same app, for different 
purposes).

This is probably a basic issue but any help regarding this would be greatly 
appreciated.

Thanks!

Internationalization Issues

Hi Everyone,
I'm having a lot of trouble with i18n. My templates don't display all the
translations (i've already checked for the "fuzzy" tag).
I have no idea what could it be, any thoughts? Anything may help, i've been

Is this a bug in django? template_context_processors processed in views without RequestContext context_instance.

[Ricardo L. Dani]

Hello everyone,

I'm having a issue with template_context_processors requests and views that
do not use the context processors, i.e. in a render_to_response without use
of RequestContext.

For example, in my TEMPLATE_CONTEXT_PROCESSORS, as default, I have a
"django.contrib.auth.context_processors.auth", this context processor loads
in the context 2 variables like user and perms making 1 or 2 queries in
database.

In other way, i have a view like this:

def test_view(request):
return render_to_response('template.html', {'list': range(5)})

# template.html
# {% if list %}{% for i in list %}{{ i }}{% endfor %}{%
endif %}

Teoretically, this view don't use the django ORM and not use context
processors, so a request to this view can`t touch in the database.

But, for my surprise, I enable the mysql.log and with a tailf in the log I
discover thats every request to the test_view pass in every
TEMPLATE_CONTEXT_PROCESSORS and the lazy querysets are called too. In my
opinion it can`t be happened.

I'm using django 1.3.1.

Can anyone help me?

Thanks

Error 500 instead of 404

[Ricardo F. Teixeira]

Hello everybody!

I'm having a strange error.
I already searched for this error and there's quite a lot of
discussion about it. But I didn't find a proper answer that fits me.
So... when I set DEBUG to True and access an invalid URL Django
returns me a 404 error page, but if I set DEBUG to False it gives me
an 500...

Firstly I thought it was something wrong with my project so I started
a new one, with only the following basics options.
I can assure you that I only edit those 3 files (views.py, urls.py and
settings.py).

In settings.py I only change from DEGUG=True to DEBUG=False.

ricardo@maggie:~/ola $ ls
__init__.py  __init__.pyc manage.pysettings.py  settings.pyc
urls.py  urls.pyc views.py views.pyc

ricardo@maggie:~/ola $ cat urls.py

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

manage.py dumpdata json storage problem

[Ricardo L. Dani]

Hello django-users,

I'm having problems trying to serialize the data of a postgresql db of my
business application (lots of lots of data)

Using the command:

./manage.py dumpdata > data.json

But, the execution of this command takes a long time and the ram and swap of
the computer reachs the limit causing a exeption:

django.db.utils.DatabaseError: out of memory for query result

The question is, somewone knows a way to this command write in the data.json
directly or in demand? I believe this is the problem and solution, am I
correct?

graciously,

django-admin inspectdb does not detect NULL columns for PostgreSQL database

[Ricardo L. Dani]

Hi everyone,

I have the same problem of this ticket from django trac:
https://code.djangoproject.com/ticket/7783

The PostgreSQL database introspection does not detect NULL columns,
cursor.description does not return the null_ok field, so database
introspection does not add null=True to column definitions. The
is_nullable column in information_schema.columns does contain this
information, however.

A patch was subimitted, but i can't apply this 'cause the version of
django that's the patch was appliend is different to 1.3 (the version
i use).

Somebody knows what version of django this patch is applied? Or a
other way to solve this problem?

Regards

Re: Multiple INNER JOIN without raw SQL

[Ricardo F. Teixeira]

Hi Jason.

You are correct, Package.objects.all() does the job partially, but I
forget to mention (sorry) that what I want is all coments from a
specified package.

WHERE Package.name = 'some_package_name'

So using Packages.objects.all() does not retrieve, or dos not select,
all the comments from that package.
I know I can filter by name, package_list =
Package.objects.filter(name='something') but that doesn't give me the
comments for that package, because there's no relation between those
tables. The bad side of this approach is that I cannot change the ERM
for this database. I'm guessing that the only option is using raw
queries.

Multiple INNER JOIN without raw SQL

[Ricardo F. Teixeira]

Hi everyone!

Without using raw SQL queries how can I make multiple joins using this
model?

I'm trying to get something like this:

SELECT Package.package, Release.release, Release.version,
ContribComment.*
FROM ContribComment
INNER JOIN Contrib
ON Contrib.id = ContribComment.fk_contrib_id
INNER JOIN ContribRelease
ON ContribRelease.fk_contrib = Contrib.id
INNER JOIN Release
ON Release.id = ContribRelease.id
INNER JOIN Package
ON Package.id = Release.fk_package

Is that possible to anchive something like this without using raw SQL
queries?
I'm asking that because I can't find any example with multiple inner
joins that is similar to my model.

class ContribComment(models.Model):
fk_contrib_id = models.ForeignKey(Contrib)
subject = models.TextField()
text = models.TextField()
ratings = models.IntegerField()

class Contrib(models.Model):
username = models.TextField()
city = models.TextField()

class ContribRelease(models.Model):
fk_contrib = models.ForeignKey(Contrib)
fk_release = models.ForeignKey(Release)

class Release(models.Model):
fk_package = models.ForeignKey(Package)
release = models.TextField()
version = models.TextField()
distribution = models.TextField()
arch = models.TextField()
summary = models.TextField()
description = models.TextField()

class Package(models.Model):
name = models.TextField(unique=True)
homepage = models.TextField()
snapshot = models.TextField()

Thanks,

Re: Cannot import models.py in views.py

Hi Shaw and Bill,

Yeap, I already have done that with no luck.

I'm starting to became confuse. If I try the same thing with urls.py
which import two functions frow views, it shows that django settings
module is not defined and does not throw an invalid module. Basically
in urls.py python can import views.py but in views.py cannot import
models.py? Weird…

Sugestions? Append in PYTHON_PATH my app dir?

Cannot import models.py in views.py

[Ricardo F. Teixeira]

Hi list : )

I'm having a strange problem. I'm developing a webservice that
communicate with a database.
In my views.py file I'm trying to import models.py to manage some
queries but I got an error in views.py when I import models.py.

ricardo@vulcanus:~/webservices/reviewsapp$ python views.py
Traceback (most recent call last):
  File "views.py", line 13, in 
from reviewsapp.models import Category
ImportError: No module named reviewsapp.models

ricardo@vulcanus:~/webservices/reviewsapp$ ls models.py
models.py

In settings.py I have:
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'webservices.reviewsapp',
)

So in theory this should work, and I can(!) but only in django shell.

ricardo@vulcanus:~/webservices/reviewsapp$ python ../manage.py shell
In [1]: from reviewsapp.models import *

In [2]: C
Category Contrib  ContribComment   ContribReleases
ContribRoles ContribVersions

And it shows my model.

What I'm doing wrong here?

Thanks,

Ricardo F. Teixeira

... etc

but i need a 

With django 1.2 i get this using:

class InscricaoForm(ModelForm):

class Meta:
model = Inscricao
widgets ={
'possiveis_areas_de_interesse' : RadioSelect,
'regime_dedicacao_curso' : RadioSelect,
'vinculo_empregaticio' : RadioSelect,
'interesse_bolsa_estudos' : RadioSelect,
'conhecimento_linguas_estrangeiras' : RadioSelect
}
