Re: Weird error like tickets 8892 and 10811

[Lachlan Musicman]

ergh. Rookie error. Subtle bug in the Job class - see the save override:

def save(self, *args, **kwargs):
if not self.slug:
  self.slug = self.job_number
  super(Job, self).save(*args, **kwargs)


Note that the call to super is only reachedwhen there is no slug.
The fix is simple:

def save(self, *args, **kwargs):
if not self.slug:
  self.slug = self.job_number
super(Job, self).save(*args, **kwargs)


cheers

Re: Using Sum function in Models.py

[Lachlan Musicman]

I recommend you send through the code for model you are talking about
- since it doesn't make sense to have a sum of a single field of a
model.


Do you really want to keep the sum in the DB and not calculate it as needed?

Maybe if you told us what your desired end point is, we could suggest
best practice?

cheers

The idea is that a beautiful image is frameable. Everything you need
to see is there: It’s everything you want, and it’s very pleasing
because there’s no extra information that you don’t get to see.
Everything’s in a nice package for you. But sublime art is
unframeable: It’s an image or idea that implies that there’s a bigger
image or idea that you can’t see: You’re only getting to look at a
fraction of it, and in that way it’s both beautiful and scary, because
it’s reminding you that there’s more that you don’t have access to.

Re: Weird error like tickets 8892 and 10811

[Lachlan Musicman]

Ok, I now understand why this happens:

>>> x == j
True
>>> j == x
True
>>> j.findings
'data'
>>> x.findings
u''

https://docs.djangoproject.com/en/dev/ref/models/instances/#eq

"with the same primary key value and the same concrete class are
considered equal. "

(no docs in 1.6, but I presume that was oversight rather than a
change, since no changes are referenced in the docs.)

Re: page not found errors for most urls but main landing page displaying okay

[Kelvin Wong]

If you have access to your logs, check your logs to figure out where those 
requests are going.

You can also SSH into the server and temporarily turn on the DEBUG=True, 
TEMPLATE_DEBUG=True and let Django tell you what is going on.

Without seeing your fcgi script, my guess is that it is Apache not mapping 
the request to your WSGI file/fcgi script. Double check your htaccess file 
mod_rewrite directives.

Weird error like tickets 8892 and 10811

[Lachlan Musicman]

I have run up against this bug before:

https://code.djangoproject.com/ticket/8892

Recently, it was updated to "duplicate of"

https://code.djangoproject.com/ticket/10811

The TL;DR is

Sometimes when you have models with O2O or FK you can lose data if the
models are saved in the wrong order.

I'm having a similar yet different issue, using Django 1.6.5

I have a Job model with subclasses

class Job(models.Model):
  job_number = models.CharField("Job Number", max_length=20,
unique=True, db_index=True)
  date_opened = models.DateField()
  slug = models.SlugField(max_length=20, unique=True)
  def save(self, *args, **kwargs):
if not self.slug:
  self.slug = self.job_number
  super(Job, self).save(*args, **kwargs)

class WorkshopJob(Job)
  job = models.OneToOneField(Job, parent_link=True)
  invoice_number = models.CharField("Invoice Number", max_length=30, blank=True)
  reported_fault = models.TextField()


And here we see a similar result:

>>> j = WorkshopJob.objects.get(id=9)
>>> j

>>> j.date_opened
datetime.date(2014, 6, 26)
>>> j.invoice_number
u'123'
>>> j.findings
u''
>>> j.findings="The CPU doesn't work"
>>> j.findings
"The CPU doesn't work"
>>> j.save()
>>> j.findings
"The CPU doesn't work"
>>> j = WorkshopJob.objects.get(id=10)
>>> j.findings
u''
>>> j = WorkshopJob.objects.get(id=9)
>>> j.findings
u''
>>>


Is this expected behaviour?

Is this caused by having overridden the save method on the Job class
and then not following up with an overridden save method on
WorkshopJob?

As another example:

>>> j = WorkshopCivilJob.objects.get(id=9)
>>> j.findings
u''
>>> j.findings="data"
>>> j.findings
'data'
>>> j.save()
>>> j.findings
'data'
>>> x = WorkshopCivilJob.objects.get(id=9)
>>> x.findings
u''
>>> x == j
True
>>> j == x
True
>>> j.findings
'data'
>>> x.findings
u''
>>>

Now my brain hurts.

How can I fix this?

cheers
L.

Re: How to store/model reachable data in django.

You don't want to use a csv. Store them in a db table cell. Even if you

Re: page not found errors for most urls but main landing page displaying okay

[Lee]

Thanks - it must be a problem with the site accessing templates but I can't 
figure it out. This django project works on another server but I have 
copied it to a shared host webserver  (Bluehost) and am running it with 
fcgi so maybe the problem is in the setup.

I am focusing on one url and template, but all have the same problem except 
the main landing page, which does work.

The url http://mysite/project/map/nav/ shows the right text without any 
styling
This is the url pattern for this page in urls.py.
url(r'^map/nav/$', 'citi_digits.views.mapNavigation', name='mav_nav'),

The view for this url references the template:
def mapNavigation(request):
"""
Loads the map navigation elements
"""
#get all classes
#get classes
classes = Teacher.objects.values_list('className', flat=True)
return 
render_to_response('map_navigation.html',{'classes':classes},context_instance=RequestContext(request))

In the settings.py the setting for templates is:
TEMPLATE_DIRS = (
os.path.join(PROJECT_ROOT, '..', 'citi_digits','templates'),

I also tried an absolute path and put the templates in www but this did not 
work.

My static settings are:

STATIC_ROOT = '/home5/user/public_html/project/static/'
STATIC_URL = 'http://mysite.org/project/static/'

Re: Time Zone Problem when following on tutorial

[Mike Dewhirst]

Jerry

I just figured it out and it is simple. Time is constant and all you need 
to do is decide how* you want to display it. The TIME_ZONE setting tells 
the server. 

An event happens at the same time everywhere in the universe (there may be 
Einsteinian exceptions to this) and you can store that time in the database 
relative to UTC. If you choose Shanghai time in settings then all recorded 
times are stored/displayed as Shanghai time. That is totally fair. People 
elsewhere just need to know the system is runing on "Shanghai time"

I don't know why it was necessary to switch the Django default to UTC 
except that lots of people use and can think in UTC as well as local time. 
The entire aviation industry for example. There may be a tiny performance 
gain avoiding calculating a local time.

The backwards compatibility thing is vital because if you have history in 
your database you can't just switch the base from UTC+8 to UTC without 
making all the stored times invalid by 8 hours.

What do you think?

Mike

Handling checkbox inputs

[Saloni Baweja]

I'm building a small app that at first displays the form containing the 
checkboxes and asks the user to select one or more of them and then 
displays the name of only selected ones. 
This works fine. Now, I want to display the data only corresponding to the 
fields that the user has checked or selected. This creates problem as I'm 
not able to fetch the attributes or objects from the list object named ' 
info ' since it is list of unicode strings like [u'name', u'marks'] . In 
display.html {{ j.i }} is not being fetched as  ' i ' isn't an object but 
unicode string whereas ( when tried in shell ) j.name, j.marks fetches the 
information marks and name being objects or attributes. 
Templates :

 # form.html



 Name 
 Roll No. 
 Branch 
 Session 
 Marks 
 Backlog 
  


# display.html


You selected for : {{ nothing }}
{% for i in info %}
  {% for j in list %}
{{ j.i }} 
  {% endfor %}
{% endfor %} 
{% if error %}
  Please select atleast one field.
{% endif %}


# views.py

def index(request):
return render(request, 'index.html')

def display(request):
   list = Student.objects.all()
   if 'info' in request.GET:
   info = request.GET.getlist('info')
   return render(request, 'display.html', { 'info': info, 'list':list })
   else:
   
   return render(request, 'display.html', {'error': True, 
'nothing':'nothing'})

Re: on manage.py migrate appname I get: AttributeError: 'module' object has no attribute 'Migration'

[Michael Lind Hjulskov]

Hi Erik

I solved it.. You vere right I should check again the files in migration
folder
It was my IDE (Pycharm) which for some reason sometimes fail on uploading
files. So there was missing a few files, in a migrations folder
Sorry I didnt know that - Pycharm is still new for me. I'm use to Filezilla
which would prompt such error more clearly

Let me know if I can help You some day
I work with ecommerce and my number is 22116322

Thank You very much

Michael

Check your migrations folder and make sure you only have South migration files

Re: page not found errors for most urls but main landing page displaying okay

[Michael Lind Hjulskov]

Hi

I had the exact same problem a few days ago. It was one of my templates 
that suddenntly was emty. very spooky
Or maybe you have an "extends" somewhere that is not correct
I would debug by looking in the relevant view and see which template is 
called, and the simplify that template to test if bug is in templates or 
elsewhere

page not found errors for most urls but main landing page displaying okay

[Lee]

I have copied a Django project to my web server from a repo and am getting 
the correct initial landing page for the website with the right styling 
when I go to the main URL. Most other urls give "page not found" errors. 
This includes the divs that are called on to make menus on the main page so 
the "Page not found" error is printing over the main landing page. 

I'm not sure where to start with diagnosis - any thoughts would be 
appreciated.

I have checked the urls.py file and have tried to go directly to the URLs 
listed starting with http://mysite.org/project/ ...

urlpatterns = patterns('',
# index.html gives a page not found error
 url(r'^$', 'project.views.index', name='index'),


# These go to an unstyled page with correct text
url(r'^signup/$', 'project.views.signUp', name='signup'),
url(r'^login/$', 'project.views.login', name='login'),
url(r'^logout/$', 'project.views.logout', name='logout'),


# These also give a page not found error

url(r'^$', 'project.views.index', name='index'),
url(r'^map/nav/$', 'project.views.mapNavigation', name='mav_nav'),
url(r'^interview/new/$', 'project.views.interviewSelect', 
name='interview_select'),
url(r'^interview/player/$', 'project.views.interviewPlayer', 
name='interview_player'),
url(r'^interview/retailer/$', 'project.views.interviewRetailer', 
name='interview_retailer'),
url(r'^popup/(?P.+)/(?P.+)/(?P.+)/(?P.+)/(?P.+)/(?P.+)/(?P.+)/(?P.+)/(?P.+)/$','project.views.popup',name='popup'),

testing equality in template tag

[Lee Hinde]

with view code like so:

import calendar
months_choices = []
for i in range(1,13):
months_choices.append((i, calendar.month_name[i]))
context['months'] = months_choices


and

context['default_month'] = today.month

I have this snippet in a template (my first use of lists like this):


{% for month in months %}

{{ month.1 }}
{% endfor %}



The issue is the  {% if default_month == month.0 %} always returns false...
The rest of the select is properly built - I get a number for the value and
the month name as the label.

Why?

  Hello,

 I setup Django successfully on my shared Bluehost account following the 
 tutorial below: http://www.nyayapati.com/srao/
 2012/08/setup-python-2-7-and-django-1-4-on-bluehost/

 I am now having problems with a Django project I have copied from a 
 GitHub repo to my Bluehost directory. I am getting this error when I run 
 python mysite.fcgi in my virtualenv

 go-1.5.1-py2.7.egg/django/conf/__init__.py", line 134, in __init__
 raise ImportError("Could not import settings '%s' (Is it on 
 sys.path?): %s" % (self.SETTINGS_MODULE, e))
 ImportError: Could not import settings 'mysite.settings' (Is it on 
 sys.path?): No module named settings

 Any thoughts on where to look for errors? I have checked .htaccess and 
 the mysite.fcgi file in my www directory, the pointer to settings in my 
 manage.py and these seem as they should be. Running python manage.py 
 runserver on the project says there are no errors.

Re: Django Login/Session Not Sticking

[LaPerl]

Hello all,

I'm not sure if you  discovered the problem, but if you have different 
types of authentication backends, maybe the problem is on the session 
objects. Did you do a delete?.
See the NOTE in this chapter: 
https://docs.djangoproject.com/en/1.6/topics/auth/customizing/#specifying-authentication-backends

Hope it helps

How to store/model reachable data in django.

[Subodh Nijsure]

Hello

I have need to store data that can be graphed. Example I have mobile app
that collects temperature every 30 seconds for say 5 min and uploads these
samples via REST api to my database. I happen to be using django for
visualization.

Question I am pondering is what is the best way to store these values in
database. Store each point as record in db or store csv file? Downside if
trying to upload single point means lots of request to web site to upload
data. Csv file means I can't graph across data collected over say one
month.

Any tips on how to manage graphable data within django?

Subodh

on manage.py migrate appname I get: AttributeError: 'module' object has no attribute 'Migration'

[Michael Lind Hjulskov]

Hi there :)

I'm stuck with this problem 
when I run python manage.py migrate myappname i get the following error:
AttributeError: 'module' object has no attribute 'Migration'

I remember I had this problem before, and I remember that I solved it by 
deleting all pyc files  - I tried that - still error

any clues?

Thank You

django not reconnecting to database after mysql server restart

[cercatrova2]

  
  
Dear django'ers:


Configuration: django 1.6.5, mysql connector/python 1.2.2, mysql
server 5.5.37, apache worker 2.2.22 with mod_fastcgi, and python
3.3.5 on an otherwise stock and up-to-date ubuntu 12.04 setup.


Problem: django is not reconnecting to the database after a mysql
server restart. From what I read it should connect to the database
*on each request* if CONN_MAX_AGE is 0. Access works properly in
normal operation but after bouncing the mysql server the database
access fails with an exception of "MySQL Connection not available"
and an http server restart is required. After that access works
properly again.


I've tested restarting mysql server with all of the above except
django i.e. with just a simple wsgi script and no http server
restart is required so this doesn't seem to be a problem with the
mysql connector/python adapter itself but between django and the
adapter i.e. something in django/db/backends/__init__.py or
mysql/connector/django/base.py. The ensure_connection() method in
backends/__init.py__ just doesn't seem to be doing what it should.

Am I misinterpreting what I read about reconnecting?

Re: Using session data to populate multiple forms

[Aaron Reabow]

haha - okay

*model_instance.participant = request.session.get('participant')*

works perfectly.

I thought the incorrect use of objects was just the start :)

Thanks Daniel, much appreciated.

Yes, you will need to use a third-party app such as django-selectable

Re: Using session data to populate multiple forms

Perhaps I should be more specific.

How do i populate some fields in a table from a form, and other fields from 
session variables in the view  (or the template or the model if that was 
more appropriate)

many thanks,

Re: Time Zone Problem when following on tutorial

It respects the settings.py time zone not the system locale.

This means your question needs to be addressed by someone smarter than 
me.

I still have a question. In your code, which part should I change in

My settings uses Australia/Melbourne and Postgres stores time
correctly as UTC+10 (or UTC+11 in daylight saving time).

But as it happens I'm in New Zealand for a couple of days. So I'll
change my laptop location to Wellington tonight and log in and create
some test entries and knowing when I do that I should be able to check
the results after switching the laptop back to Melbourne time.

Now I think of it I could pretend I'm in Shanghai :)

You can see from the above that I half-believe pytz uses the system
locale to figure out the UTC offset. But I suppose it might be
TIME_ZONE in settings.

Have to go out now. I'll report back later

This a very good question. Especially considering the variability
between databases. At least I think so - I use Postgres and that 
seems

to store times in UTC. In my case it is accidentally just what I
want so
I'm not changing anything.

But just in case, I use the following utility everywhere ...

import pytz
from datetime import datetime

def when():
  return datetime.now(tz=pytz.utc)

I wish I understood (or had the time and brainspace to commit to
memory)
exactly how it all works. I think the target audience for the
documentation is somewhat smarter than I.
