Re: django on rhel5 with both python2.4 and python2.7 confusion

[Kelvin Wong]

Question one...

The gist is:

1. Set up Virtualenv and Virtualenvwrapper (lots of howtos on the web for 
this - find one written in the last year)
2. Set correct environment keys to point to the right Python (similar to 
the following, you paths may be different)

# ~/.bashrc
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python2.7
export VIRTUALENVWRAPPER_VIRTUALENV=$HOME/.local/bin/virtualenv-2.7
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Projects
source $HOME/.local/bin/virtualenvwrapper.sh

3. Make a virtualenv: like this $ mkvirtualenv myappenv
4. Install Django into the virtualenv (you should have been dumped into it 
after you made it): (myappenv) $ pip install Django
5. Check which django-admin.py you are using

$ which django-admin.py
/home/myuser/.virtualenvs/myappenv/bin/django-admin.py

Hint: Webfaction uses CentOS with many different types of Pythons. 
Searching their support website may be helpful.

---

Question two: Use mod_wsgi rather than mod_python. See warning at the top 
of the Dj1.4 docs

https://docs.djangoproject.com/en/1.4/howto/deployment/modpython/

Setting up a Django app is more complex than setting up a PHP app (one 
persons opinion). The benefit is that at the end of the ordeal you will be 
running Python and not PHP (one persons opinion).

Both of them are True.
USE_I18N = True
USE_L10N = True

Looks to be some for of a Language issue.  Unfortunately, am not much of an
UTF-8 expert, but can you check your templates once more.

Re: Python Nested For Looping MultiTable Association Question

[G Z]

ok so I added == to my if statement and independently verified that the 
values were displaying and are correct. So I was wrong though .id is not 
.CUSTOMERID because I returned self.name for the customer model it needs to 
match the strings

so i have 

{% for e in customers %}
{% for d in vms %}
{% if e.NAME == d.CUSTOMERID %}
 {{ e.id }} - {{ e.NAME }} - {{ 
d.VMNAME }$
{% endif %}

e.name - {{ e.NAME }}
d.customerid - {{ d.CUSTOMERID }} 

//I did this to validate I was getting data and the names match when they 
are displayed but the if statement doesn't display anything.

{% endfor %}
{% endfor %}

use == instead of = in your if statement.

FormWizard confirmation step logic and Allow dynamic form classes with WizardView

[Fabio Caritas Barrionuevo da Luz]

Hello django users.

About the ticket 21644[1] - "FormWizard needs confirmation step logic" 
and ticket 21667[2] - "Allow dynamic form classes with WizardView"

I would like your opinions about the proposed implementation by user 
nickname123[3].

Remember that an implementation is in very early stage.

I added two more classes to at least to me, are useful

see: https://github.com/thenewguy/django_formwizard_mixins/pull/2

Re: Python Nested For Looping MultiTable Association Question

[G Z]

out of my stupidity i refined it a bit

{% for e in customers %}
{% for d in vms %}
{% if e.id = d.CUSTOMERID %}
 {{ e.id }} - {{ e.NAME }} - {{ 
d.VMNAME }} 
{% endif %}
{% endfor %}
{% endfor %}

why doesn't this work.?

Re: Python Nested For Looping MultiTable Association Question

[G Z]

I don't know why this isn't working..


from django.shortcuts import render
from django.http import HttpResponse
from vmware.models import Customer
from django.shortcuts import render_to_response
from vmware.models import Vms

def index(request):
customers = Customer.objects.all
vms = Vms.objects.all
ctx = { 'customers':customers, 'vms':vms}
return render_to_response('index.html', ctx)

my views.py

the loop now reads

{% for e in customers %}
{% for e in vms %}
{% if e.VMIDS = e.id %}
 {{ e.id }} - {{ e.NAME }} - {{ 
e.VMNAME }} 
{% endif %}
{% endfor %}
{% endfor %}

The trouble is in your VMSpec model's `__unicode__` method. That actually 
needs to return unicode, but you are returning the value of the VMID 
ForeignKey field, which is a VMS object. You should either return 
`unicode(self.VMID)`, or choose another field to be the unicode 
representation.

Check closely what you are being told here.

Django tried these patterns:

"^admins/"
"^customers/"

and neither matched the current URL "customers".

Computers are precise machines - "customers" is not the same as
"customers/". You must be precise.

What version of Python? 2.x or 3.x?

Presumably your email client is converting plain single and double
quotes to smart quotes and backticks, and in your source code they are
plain single and double quotes - " and ', not “ and ‘.

Django does something explicitly to force management commands to be
ascii, see here:

https://docs.djangoproject.com/en/1.6/howto/custom-management-commands/#management-commands-and-locales

There was an old case to force Django to use UTF-8:
https://code.djangoproject.com/ticket/5877

It was closed wontfix on the basis that Django respects your locale,
which it no longer does by default. There are several workarounds
listed on the first link that will restore that behaviour. Within a
view code, the rules are different, it will activate either the
language that user requests (if supported and USE_i18N=True) or
LANGUAGE_CODE otherwise.

Cheers

Tom

Hello Lloyd Dube

I fix 'utf8' to 'utf-8'.
But, same error happned.

ascii' codec can't decode byte 0xe3 in position 0: ordinal not in range(128)

"locale.getpreferredencoding() is ANSI_X3.4-1968"
is not the cause?

You can check if encoding the arguments manually works:

Re: query on models

[Rafael E. Ferrero]

You are using Ques for related Subject and QuestionBank... just make a
method in Ques class who filter the Ques model with some subject parameter
or do it in your view like:
   qs = Ques.objects.select_related().filter(subject='some_name')


I'm missing something really big? or i miss understud your question?

Re: Centos 6.5 Python 3.3.x Django 1.6 Apache 2.2

[Guillem Liarte]

Timothy,

Thanks you, but SELinux here does not seem to be the issue. I tried with 
enforcing/permissive/disabled and the effect is the same.

I belive the problem to be in the os path in the seetings:

---

import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
...
...







 
--

in wsgi.py :



import os, sys
sys.path.append('/data/app/guillem-py3-dj17-test/guillem_test/guillem_test')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "guillem_test.settings")


---

python -c "import sys; print(sys.path)" 
['', '/data/app/guillem-py3-dj17-test/lib64/python33.zip', 
'/data/app/guillem-py3-dj17-test/lib64/python3.3', 
'/data/app/guillem-py3-dj17-test/lib64/python3.3/plat-linux', 
'/data/app/guillem
-py3-dj17-test/lib64/python3.3/lib-dynload',

'/opt/rh/python33/root/usr/lib/python3.3', 
'/data/app/guillem-py3-dj17-test/lib/python3.3/site-packa
ges']




I am reading about the differnces for mod_wsgi from python2.x to python3.x 
but I fail to find clear documentation about how the wsgi.py and  
settings.py should look like in python3.

Re: query on models

[Anushree Jangid]

No I start with subject model. There I have created subjects like General
knowledge, English etc. ​Then I create question banks Like for General
knowledge I have created GK1, GK2 and GK3 . Then when I enter a ques in the
Ques model there I specify that the question is related to which subject
and which question bank.
For e.g In Ques model I enter
content=what is friction
subject=General knowledge
ques_bank=GK1


​Now for eg I want to know the question banks associated with subject​
General knowledge, then it should tell GK1 GK2 and GK3
Assume all the questions related to the subjects along with their question

Re: django on rhel5 with both python2.4 and python2.7 confusion

[Timothy W. Cook]

A good place to start is with this thread:
https://groups.google.com/forum/?utm_medium=email_source=footer#!msg/django-users/_0RTNcYyCSI/24QinBTEnX8J


Be sure to include CentOS in your searches for clues about this setup since
many people use CentOS instead of RHEL.

html email function to a large recipient list problem

[MikeKJ]

I have these functions to send update emails to a subscriber list 
(recipients) but for some reason I cannot seem to fathom it does:

Connect
Send Email A
Connect 
Connect
Send Email B
Send Email B
Connect 
Connect
Connect
Send Email C
Send Email C
Send Email C

etc etc

Can anyone see where the incrementing is happening because I can't.
Interestingly it seems that even though the logger says each email is sent 
multiple (by increment, like the 1000th address on the list theoretically 
should get the same email 1000 times) it doesnt, just the one email or so 
it appears, if anyone has an explanation for that as well I would be 
interested

Re: Detail View Question

[visionary800]

I am not sure my first reply worked, but here it goes again.
Your template is using {{ post.NAME }} when I believe it should be using {{ 
customer.NAME }}.  The context name that is used in the template is 
obtained by default from the model and in your case, you are using model= 
Customer.  If you want to rename so that you can use {{ post.Name }}, you 
will have to use 'context_object_name = post'.  But I suggest you edit your 
template. 

url(r'^(?P\d+)$', DetailView.as_view(
model = Customer,
template_name="customer.html",

context_object_name='post')),# Do this only if you want 
to use {{ post.NAME }}


get_context_object_name(*obj*)

Return the context variable name that will be used to contain the data that 
this view is manipulating. If 
context_object_nameis
 
not set, the context name will be constructed from themodel_name of the 
model that the queryset is composed from. For example, the model Article would 
have context object named 'article'.
Ref: 
https://docs.djangoproject.com/en/1.6/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_context_object_name

hope that works.

django on rhel5 with both python2.4 and python2.7 confusion

[David Malcolm]

I have been tasked with finishing a build for production that was 
interrupted due to another staff member leaving at short notice. It's 
RedHat Enterprise Linux 5 and there are two versions of python on the box. 
If I type python I get version 2.7. However if I try and use 
django-admin.py I find that it is trying to use python version 2.4. How do 
I specify to Django that I want to use python 2.7? I've seen multiple 
supposed answers on the net but nothing actually seems to answer my 
specific question. I'm fairly experienced on linux but have never had to 
setup django and python before. My Apache, php, phpMyAdmin setup is all 
working properly (after I sorted out some other issues),  but my second 
question is how do I wire up python/django to apache (or httpd as rhel5 
calls it). I've tried using mod_wsgi but have been told I must use 
mod_python. Advice or pointers to relevant urls are much appreciated. 
Thanks Dave, Melbourne

In the context of using

as anyone stumbled on an issue with a Model using ChainedFK and if the
queryset of chained_field in the ModelForm is changed before  rendering?

ie., if person is the chained_field in my form and I changed its queryset
before rendering as follows, then the dependent dropdowns do not get
populated while the form is rendered.

form.fields['person'].queryset = this_dept.get_persons()

regards,
Venkat
