How to ordered comments by date ???

[Ariel]

Hi everybody:

I have a little question that is simple but I haven't found it in the
documentation.
How could I order the comments by date ???
This is when I show them in the template:
{% load comments %}

{% get_comment_list for object as comment_list %}

{% for comment in comment_list %}
{{ comment.submit_date|time:"H:i"}}

{{ comment.user_name}}
{{ comment.comment}}
{% endfor %}

How could I order the comments ???
Thanks in advance.
Regards
Ariel

I have a problem with the pagination with haystack and apache solr

[Ariel]

Hi everybody:
I have a big problem with pagination using apache solr and haystack, this is
what it is happening: I have a site where the news are being indexing with
haystack and solr, but the problem is that when a I make the search the
pagination is showing me more match results that what really exists even
more results that total news in my database, for example I have only 20 news
in the database but when I make a search the pagination said 40 matching
results are found then when I navigate with the "next" link to see the other
results any result is showed.

I hope I have made a good explanation of my problem.
Could you help me please ???
I don't know why it is happening that 
Regards.
Ariel

the index.
How could I know it ???

from haystack import site
from atl_cms.content_type.models import News, Document

site.register(News)

How to serialize objects that contain a foreign key object

[Ariel]

I need to serialize a an object that has a foreign key object for example:
I have this model:

class Town(models.Model):
name = models.CharField(max_length=50)
extension = models.IntegerPositiveField()

class Restaurant(models.Model):
hot_dogs = models.BooleanField()
town = models.ForeignKey(Town)


from django.core import serializers

json_serializer  = serializers.get_serializer("json")
data = json_serializer.serialize(Restaurant.objects.alI(),
ensure_ascii=False)

But problem is that when the list of restaurant objects are serialized only
the primary key of the town object is serialized but not the name and the
extension, this is what I get:
[ {pk : '1', hot_dogs: 'True' , town: '1'}, {pk : '2', hot_dogs: 'False' ,
town: '1'}, {pk : '3', hot_dogs: 'True' , town: '2'} ]

And I would want to get the name and the extension of the town foreign key
object too.
I hope you can help me

Thanks in advance.

Problems with comment form customization ?

[Ariel]

Hi everybody:

I am implementing comments functionalities in my web application, I am
making the documentation examples.
I have customized my comment form exaxtly like the documentation:

{% get_comment_form for document as form %}

  {{ form }}
  

  


But the thing is that a field that is suppossed to be hidden is
visible and that is what I don't want, the field name is 'honeypot'
This is a normal behavior ?
Do anyone of you know how to make that field hidden again ???
Thanks in advance.
Ariel

Now I have a new question: if I want to reduce de amount of columns that the
textarea has, how could I do it ? This is not as simple as the previous
issue.
Thanks in advance.

Re: Problems with comment form customization ?

[Ariel]

That's the same I do, but if you don't take off the cols property and you
set a width size smaller than that amount of cols then the textarea shows an
ugly horizontal scroll, that I want to avoid.
Could anybody knows how to solve that ???

contextcopy = {}
message = render_to_string('bulletin.html', contextcopy)
subject = "TEST"
msg = EmailMultiAlternatives(subject, message,
from_email,['myem...@gmail.com''])
msg.attach_alternative(message, "text/html")
msg.send()

The problem is that if I don't put the image mime code inside the src

A question about field forms and the widget SelectMultiple

[Ariel]

Hi everybody, I have a form with a field that uses the SelectMultiple
widget:

class DocumentForm(forms.ModelForm):
   options = forms.CharField(label='Options', max_length=100
,widget=forms.SelectMultiple(attrs={'class':'listbox'}, choices=([(aspect.id,
unicode(aspect.title)) for aspect in aspects ])) , required=False)

How you can see the field is populated automacally from a list: "choices =
([(aspect.id, unicode(aspect.title)) for aspect in aspects ]))", this works
wonderfull when I am inserting in the database the document model.

But when I want to make an update over the document object I use the same
form and I populated the form like this:

myform = DocumentForm(instance= document)

I want that the listbox displayed with all the options available an the ones
that are inserted in the database with the document mark as selected.
For instance if all the options available are A, B, C, D and the document I
want to update has only the option A and C, I want in the list box options
A, B , C ,  D but option A and C mark as selected.

Could you please help me do that ?
How would you do it ?

Thanks in advance.

Ariel

 If you repeat that enough times there would probably be a value of 'now'
that makes those statement true.
You just gotta be patient or/and help.

And why not skip Apache, Nginx and even MySQL and develop using django and
sqlite?
Really if you are on the development stage focus on that and when you are
ready to deploy you can always come back to ask here on the list or read
over many of the tutorials available.

With something like Instant Django is just download, unzip and start using
Django in Windows.

Re: Admin css being weird

[Ariel Nunez]

Please make sure there isn't another Django version being loaded.
I experienced the same situation when I had copied admin media from one
version and the Django module loaded had another one. (i.e. Django 1.0
installed systemwide and Django 1.1 on a virtualenv)

Ariel.

I usually use it removing the 'other' version from my python path, usually
by uninstalling it.
If uninstalling the other one is not an option for you, try to find a way to
clear your python path before loading your 'preferred' Django.

Re: Help make matriz

[Ariel Nunez]

Carlos, all the info you need to enable the admin and customize it for your
app is on this page:

http://docs.djangoproject.com/en/dev/intro/tutorial02/

Specifically, look for 'list_display' and put there all the columns you want
to see on the admin interface for your model.

Ariel.

PS:
If you need more support, tell us more about how far have you been able to
go:
- Have you enabled the admin interface?
- Have you created and admin.py file for your app?
- Have you created a PruebaAdmin(models.ModelAdmin) class?

Re: how to cut and paste image into django app

Hi Margie,

I found this while googling: "drag and drop upload":

http://www.radinks.com/upload/dnd.php

Seems to use a combination of Java (applet) + PHP (server) and is not  
open source.

But it seems to prove it is possible. Just perhaps not with simple  
HTML + JS.

Thanks for (Geo)Django

[Ariel Nunez]

I just saw a commit referencing the new geography column support on
Postgis and felt the urge to drop a public thank you note to Justin
and all the other folks behind GeoDjango and Django.

(Geo)Django has done a lot for me in the past 3 years, not only
becoming a source of income; but, more importantly, a source of
inspiration!

Thanks to the django core dev team (including of course the one that
has been unusually quiet in the past few months), to the bug triagers,
to the ones that come up with feature requests over and over, and even
the ones that start flame wars that do not last long thanks to the
general polite and respectful atmosphere enforced by most people here.

Thanks one more time, I hope you all enjoy a lot what's little left of
this year, and especially take enough the time away from the computers
to enjoy with your family.

Regards,

A happy django user.

You can do it

in settings.py add:

TEMPLATE_CONTEXT_PROCESSORS = (
 'django.core.context_processors.auth',
'django.core.context_processors.request',
)

and in every view import:

from django.template  import RequestContext

adn finally when you make a render to response:

return render_to_response ( "TEMPLATEFILE",   {},  context_instance = 
RequestContext ( request ),  )

Re: Unable to access URL's query string using request.GET['next']

[Ariel Calzada]

You can't see next variable after login because the view that process
"login form" don't return the variable in any form. You can modify this
view.

syntax usage for the Database name ??

[Eran Ariel]

Hi,

 

I am uncertain as to the proper syntax usage for the Database name.

I have a MYSQL database called "test". Does the subsequent script 
automatically point to the folder where mysql databases reside on my Ubuntu 
machine? 

 

os.path.join(BASE_DIR, 'db.test ')

 

Furthermore, the instructions as per the Django site are to provide the 
full path where the database resides… However, I am again uncertain whether 
that refers specifically to all databases and how to apply it in proper 
syntax

 

Can someone provide me with a configuration example?

 

 

Thanks in advance

 

Eran Ariel

La Salvaje Esperanza

Éramos dioses y nos volvieron esclavos.
Éramos hijos del sol y nos consolaron
con medallas de lata.
Éramos poetas y nos pusieron a recitar
oraciones pordioseras.
Éramos felices y nos civilizaron.
Quién refrescará la memoria de la tribu.
Quién revivirá nuestros dioses.
Que la salvaje esperanza siempre sea tuya, querida alma inamansable.

Using Django as a framework to deploy python script on a website:

[Eran Ariel]

Hi, I am interested in Django as a platform to deploy applications using 
mod_wsgi, accordingly, whether existing Django libraries such as the forms 
library could be applied for this purpose as user initiated POST requests – 
to pass the variables.  I can place my scripts within the models.py file, 
accordingly, the script runs at the shell upon running "python manage.py 
runserver" command, however, I cannot see any output at 
http://localhost/8000 (at least for now).

How do I get my python application "browser enabled"?

getting raw_input('something') instantiated from browser

[Eran Ariel]

I have developed a python application to which I am interested in allowing 
users to access it via web browser.  I am new to implementation.  I need to 
"call" the raw_input('your calculation')  from the browser and return the 
results to the browser – GET or POST. 

I have added the python script into the views.py file (in any case, it 
would run if I added it in the models.py file) 

It makes sense to create an auxillery folder to contain my python 
application and communicate with it accordingly.

Any suggestions?

How send data to UpdateView from javascript. (Django 1.5)

[Ariel V. R.]

Hello:

Hello:

I need to send data from html using javascript to UpdateView. Django sends 
me an error:  "Generic detail view MatterUpdateView must be called with 
either an object pk or a slug."

I think that the problem exists because the method as_view() does not 
receive the correct data.

Re: How send data to UpdateView from javascript. (Django 1.5)

[Ariel V. R.]

I know the solution, this appear in the django documentation, but no resolv 
my problem.  I redefine "dispatch" function in Django 1.4.X, 

class MatterUpdateView( UpdateView ):
template_name = 'object_add.html'
success_url = '/manage_p1/list/'
model = Matter
form_class = MatterForm

def dispatch( self, request, *args, **kwargs ):
if not kwargs :
kwargs['pk'] = request.GET.get('pk', '')
if not bool( kwargs['pk'] ):
kwargs['pk'] = request.POST.get('pk', '')


This code resolve the problem, but dose not in Django 1.5, I not know what 
to change in this version.

Re: Introducing myself and my first question

Hi Martin,

I myself am new in Django, here's one tutorial I believe is worth visiting
when setting up your environment:

Re: moving from sqlite3 to mysql

[Ariel E. Isidro]

"Or can I create the database, (presumably directly in the shell), and then
empty it, as these instructions say, and that will take care of it? I
frankly didn't understand why I would need to 'empty' a new and empty
database, but that's what it says. "

With sql lite, everything will be created for you.
While with MySQL,  you should create the database directly in the shell,
and this should give you an empty database.  The Django tables will be
created after configuring your settings, and running  syncdb.

Re: moving from sqlite3 to mysql

[Ariel E. Isidro]

1. before exiting mysql, you should grant permission to a user,i.e.
grant all privileges on django_1.* to username@'localhost' identified by
'userpassword'
replace username, userpassword with your own
2. exit mysql console
3. modify settings.py to add your username, password, host (localhost), and
port (3306)
4. run python manage.py syncdb

Django revision for ORM aggregation patch

[Ariel Mauricio Nunez Gomez]

Does anybody know which revision of django works with the latest patch in
the ticket #3566
http://code.djangoproject.com/ticket/3566

I tried unsuccesfully with django 1.0rc, 1.0 and 1.0.2, everytime different
rejections, and when I try to fix them by hand I always get a 'SELECT FROM
...' invalid clause error.

I also contacted Nicolas off list and he said he was gonna try to update the
patch to work against trunk in the next days or so.

So I think I would better wait a week or so and see what happens, I already
read all the docs on the patch, this certainly looks great.

Re: Django newbie observation

[Ariel Mauricio Nunez Gomez]

I think pinax basic_site is pretty much what you want/need for a
sample_website.
I would be +1 for a link to Pinax project at the end of the tutorials.

Ayayalar:
pinax-0.5.0.tar.gz 
Once the download is complete, uncompress it and you should be able to cd
intoprojects/complete_project/ or projects/basic_project/ and run
./manage.py syncdband ./manage.py runserver to get running immediately.

Should you need more information, checkout:
http://pinaxproject.com/docs/trunk/install.html

FormWizard: Setting up a ChoiceField.choices based on previous forms,

[Ariel Mauricio Nunez Gomez]

Hello list,
Today I started using FormWizard and could not find a clean way to populate
a choices field based on previously submitted forms, I ended up overriding
the render method like this(The only changed line is the one highlited):
{{{
class CountryForm(forms.Form):
country = forms.ModelChoiceField(queryset=Country.objects.all())

class StaterForm(forms.Form):
state = forms.ChoiceField()

class LocationFormWizard(forms.Form):
  def process_step(self, request, form, step):
if step == 0 and form.is_valid():
self.state_choices= states_from_country(form.data['0-country'])

def prepare_form(self, request, form, step):
if step == 1:
form.fields['state'].choices = self.state_choices
return form

def render(self, form, request, step, context=None):
"Renders the given Form object, returning an HttpResponse."
old_data = request.POST
prev_fields = []
form = self.prepare_form(request,form, step)
if old_data:
hidden = forms.HiddenInput()
# Collect all data from previous steps and render it as HTML
hidden fields.
for i in range(step):
old_form = self.get_form(i, old_data)
hash_name = 'hash_%s' % i
prev_fields.extend([bf.as_hidden() for bf in old_form])
prev_fields.append(hidden.render(hash_name,
old_data.get(hash_name, self.security_hash(request, old_form
return self.render_template(request, form, ''.join(prev_fields),
step, context)
}}}

Is there a hook missing to do what I needed or am I missing something?

Re: best way to do tabs?

[Ariel Mauricio Nunez Gomez]

Margie, I agree the current metod for adding new tabs in Pinax is kind of
cumbersome.

I also think ther is no need for javascript for that kind of simle stuff
(i.e. This would be an overkill
http://blog.evaria.com/wp-content/themes/blogvaria/jquery/index-multi.php)
Perhaps you may want to search for more 'css menu' examples, I think you can
getaway with just using two classes 'selected' and 'normal'

Like this guys do:

Re: best way to do tabs?

[Ariel Mauricio Nunez Gomez]

Since I think you are not (yet) using AJAX, all the logic you need should be
available to the template already.
Your main issue sems to be not having to rewrite any css files but only
change the html item 'class' attribute. The last link and code snippet on my
previous mail address that issue(Using an 'active' class on the selected
item, you can dynamically set it on your template).

Take some time to play with it and let us know how it goes.

Frameworks like jquery can also create and change css styles on the fly,
like I said I see it as an overkill for such a simple task, but it is your
bikeshed and you get to paint it any color you may want :)

Also, if you are looking for performance, you may want to find a way to use
the SQL aggregation operations (Like Count, Avg, StdDev) to help you with
your problem.

That feature is scheduled for Django 1.1 and 'may' be merged into trunk
soon, for now you can use Russell's git repo by doing:

git clone 
http://github.com/freakboy3742/django/tree/aggregation<http://github.com/freakboy3742/django/tree/aggregation>
git checkout -b --track aggregation origin/aggregation

Let us know how that goes.

Re: ForeignKey

[Ariel Mauricio Nunez Gomez]

Miguel,
Puedes tratar de reescribir tu pregunta, preferiblemente en ingles ya que
esta es una lista angloparlante.

Creo que quieres decir:
Como hago para actualizar automaticamente la lista de opciones en en campo
'grupo_pregunta' de la clase Pregunta basado en el valor del campo 'script'
en la interfaz de administracion de Django para agregar o editar el modelo
Pregunta.

La respuesta corta es: 'No hay una forma sencilla', la larga es: 'Debes
agregar un poco de javascript en el ModelAdmin para Pregunta'. [1]

--
How do I auto populate the grupo_pregunta field based on the value of the
script field in the 'Pregunta' admin edit interface.?
Short answer: There is no simple way. Long answer: Read carefully [1]
--

Miguel, si de veras quieres seguir haciendo preguntas en espanol, te
recomiendo que mejor uses django-es tal como te lo recomendaron en
django-developers.
