I agree. Now that I think of it, I will probably wait until this goes
into production (MySQL) and implement it therehow.

Re: Populate database from views

[Stephen Anto]

Hi,

if you have data in array list just use this

for list in array_list:
 modelObj = YourModel()
 modelObj.fieldname = list
 modelObj.save()

I believe it will help you... Thank you for visiting

Re: Best way to detect if a user has changed password

[Roarster]

Thanks for the answers, that was pretty much what I was expecting.  I 
haven't had a chance to test this yet but do you think it'll be as simple 
as just comparing the value with the previous value, seeing as the password 
field is (I assume) a bit different with it storing the hash rather than 
the plain text.

The password_change view takes additional arguments, one of which is
'password_change_form'. The form is responsible for changing the users
password, and by default is django.contrib.auth.forms.SetPasswordForm
(see docs):

https://docs.djangoproject.com/en/1.4/topics/auth/#django.contrib.auth.views.password_change

The form itself is responsible for changing the users password, so by
extending that class and specifying that class to be used, you can
hook directly in to the derived class's save() method and perform
whatever actions you need to when the password is changed.

Cheers

Tom

You did compile the po file catalogues to mo files, right? Otherwise,
gettext will simply return the msgid. msgctxt should be irrelevant.

Hi Stephen, thanks for the reply, but it doesn't solve it since every field
specified
in the fieldset at the Model admin needs to either exist in Model or in the
ModelForm,
and since the number of Images that I want to display is variable (let's
say between 1 and N)
I can't have N Image fields at the form, what I need is somewhat of a field
that spawns
into multiple fields based on the amount of images that I want to display.
I'm starting
to think that maybe using a many-to-many field with a custom widget might
do the job.

But i will call http://127.0.0.1:8000/portal/ and try to implements the sql 
code in this page.
 
I have by base.html in addition now " {% include "sql.html" %} ", the sql

Re: Reverse for 'app_list' with arguments '()' and keyword arguments '{'app_label': ''}' not found.

[Nick Doyle]

Had the same problem.
Seems the top-level problem is with extending the django admin template 
"change_form.html".
It has a tag in there referring to "app_list" which isn't set when we 
extend.
More than that I couldn't fix right now.

So worked around it by, for the form, change to extend *base_site.html*instead 
of change_form.html.
Means you have to specify a bit more stuff - submit button etc - but least 
it works.

CachedStaticFilesStorage headache

[florian]

Hi,

i try to use CachedStaticFilesStorage and, for now, it only gives me a 
headache!

Whay i've done : 
 1 - put STATICFILES_STORAGE = 
'django.contrib.staticfiles.storage.CachedStaticFilesStorage' in setting
 2 - DEBUG = False
 3 - add  'staticfiles': {
'BACKEND': 'django.core.cache.backends.filebased.FileBasedCache',
'LOCATION': os.path.join(ROOT_DIR, 'staticcache'),
}
   to CACHES in settings
 4 - collectstatic
 5 - replace each occurrence of {{STATIC_URL}}/* by {% static "blabla" %}, 
with the correct {% load static from staticfiles %}

So, i've read and followed the doc

Now, the css are well modified by collectstatic. The items are well tagged 
with their md5. However, each time i access a page, i get a 500 error. In 
the logs, i have the following message :

ValueError: The file 'img/favicon.png' could not be found with 


I've search if there is more doc/howto, but didn't find anything. So i 
think i'm doing something wrong, but don't know what.

Last thing : if y use the md5-tagged version in the template, it works. 
Hence, i think that CachedStaticFilesStorage can't manage to find my assets.

any idea?

thanks

You can't. A View *is* a page. Do the tutorial.

You could use class-based views and have a view that inherits from
both, and combines the contexts (this is _not_ in the tuto)

Modernizing the Tutorial

[Tomas Neme]

Now that function-based views are being deprecated, or at least that
class-based views are being favored, there should be a tutorial with
them in the docs, shouldn't it?

I don't mean replacing the current one, because that'd raise the entry
point a lot, but cloning the original tutorial, but implementing it
with class-based views, possibly placing a link to it in the generic
views docs page, would go a long way towards generating "good" habits
amongst new users, I think.

pub_date timezone

[Brendan Carroll]

Hi all
I am new to Django and I'm having an issue with some code. I am trying to 
get through the first tutorial from the Django site.
I have a file called polls/models.py and have created a class that contains 
the following code
class Poll(models.Model):
 question = models.CharField(max_length=200)
 pub_date = models.DateTimeField('date published')
 
The problem occurs when I go into the command prompt and enter the 
following line
p = Poll(question = "Whats new? ", pub_date=timezone.now())
The error is as follows: name Poll is not defined.
Appreciate any help guidance

Hi brendan,

You have the import class before using, so

from polls.models import Poll

I think you have put characters into your po file that are not in the
correct encoding. Can you describe how you are creating these "special
characters"?

Also, the full traceback may be illuminating instead of just the exception.

Cheers

Re: Date widget not HTML5

[Victor Rocha]

You need to roll out your own widget.

I assume django will have html5 support in the near future.

queryset-didn't show result.

[DjgoNy]

I have a project where i have to extract data from database whenever i 
click on it.
It should be shown in a table and it will be shown individually but 
whenever i use queryset in my view it didn't show anything
and when i commented the queryset then it will be shown all the listed data 
but not individually. in other word not the right data but there is a 
result.
what went wrong with my program. 

view.py 

class SolutionView(ListView):
template_name="Solution_list.html"
model = Solution
form_class = SolutionForm
context_object_name = "solutions"

def get_context_data(self, **kwargs):
context = super(SolutionView, self).get_context_data(**kwargs)
context['person_NOID']=self.kwargs['person_NOID']
tilstande =Solution.objects.filter( NOID= 
self.kwargs['person_NOID'])
return context

def get_queryset(self, **kwargs):
queryset =Solution.objects.filter(CPR = self.kwargs['person_NOID'])
return queryset

def form_valid(self, queryset):
queryset.save()
return HttpResponseRedirect(reverse("index"))

Solution_list.html




Solution


{% if solutions%}


{% csrf_token %}



NOID {{ person_NOID }}
SMOKING
WEIGHT
BP
 
   

{% for solution in solutions %}
 
{{ solution.NEW_DATE }}





{% endfor %} 




{% else %}
No Data.
{% endif %}




I want it to look something like this.

NOID - 123456789SMOKINGWEIGHTBPDATEDATENEW DATE

whereby everytime they came a new date it will be shown in DATE-first date 
DATE-next date DATE-and so on. 
And when user click on NEW DATE then the result will be shown on the 
appropriate table ei: smoking , weight, BP.

Thank you so much.

Re: Strange behaviour after pressing on button

[Nikolas Stevenson-Molnar]

It looks like you're submitting your request via AJAX and using the
X-CSRFToken header. It's very possible that one of your proxies isn't
forwarding that header correctly. You might try submitting it as an
actual form parameter instead.

Re: pub_date timezone

[BrendanC]

Hi erm
 
Went back over your comment and realised what you commented. 
After python manage.py I gget the python prompt>>> and then typed
from polls.models import Poll, Choice
 
then I typed: Poll.objects.all() and got the array brace [] returned.
then I typed from django.utils import timezone
 
then typed: p = Poll(question="Whats new?", pub_date=timezone.now())
This line will not run and tells me pub_date is an invalid argument.
 
Thanks again in advance

Re: pub_date timezone

[BrendanC]

Hi erm
 
I put that line in and still won't work. In my models.py file I have the 
following:
 
from django.db import models

class Poll(models.Model):
question = models.CharField(max_length=200)
put_date = models.DateTimeField ('date published')
class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(max_length=200)
votes =models.IntegerField()
 
After I entered import Poll the following would not run
python manage.py shell

Re: pub_date timezone

[Emrah Atalay]

Hi again,

Remove 'date published' string from pub_date=models.DateTimeField

from django.db import models

class Poll(models.Model):
question = models.CharField(max_length=200)
put_date = models.DateTimeField()

class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(max_length=200)
votes =models.IntegerField()

After that if you not run yet, syncdb

./manage.py

When you open shell import Poll class

from polls.models import Poll

 Hi all
 I am new to Django and I'm having an issue with some code. I am trying
 to get through the first tutorial from the Django site.
 I have a file called polls/models.py and have created a class that
 contains the following code
 class Poll(models.Model):
  question = models.CharField(max_length=**200)
  pub_date = models.DateTimeField('date published')

 The problem occurs when I go into the command prompt and enter the
 following line
 p = Poll(question = "Whats new? ", pub_date=timezone.now())
 The error is as follows: name Poll is not defined.
 Appreciate any help guidance

should Django groups and permissions be hard-coded or bootstrapped?

[Tony Schmidt]

I'm building an app that assumes the existence of certain groups and 
permissions for its workflow. For example, a "member" can log into the app 
and view and edit their personal data, but cannot see notes that would 
typically be displayed on the same screen. An "employee" can see those 
notes and create or edit their own, but only a "member manager" can delete 
or edit anyone's notes.

My issue is with bootstrapping the data for this app. I can create JSON 
fixture data for the groups, but then I have to hard-code the PKs, which 
seems like bad practice (what if a third party app I wanted to use did the 
same thing and there was a conflict?) A bigger issue is the permissions - I 
would have to add PKs to the permissions which in turn would have PKs to 
their content types.

I've read about using the post_syncdb hook to add initial data in a more 
programmatic fashion which I'm hoping will help me resolve the hard-coded 
PK issue. But I'm wondering whether this is the best solution to this 
problem, or if I'm "abusing" the Django Group and Permission concepts, 
here, and should be doing something else, like creating new models or just 
putting flags (like "is_member_manager") on my user profile model, etc.

IIRC they are in the tutorial. Not in an in depth way, but nothing is
really - it's just enough to get one started. The views are well
documented in the rest of the docs, and it's easy enough to
understand. Also worth noting that they are referred to as "generic
views" in the tutorial, not class based views.

Re: Documentation helpers in the admindocs (django 1.4)

I think this is a bug in 1.4 that is probably addressed in the dev version.
The model docstring is not run through the markdown to HTML routine in the
django version I'm using. Was simple enough to patch locally.

So, as Lachlan pointed out, the current tutorial 4 *does* use class-based
generic views.

However, there is also scope for a focussed tutorial about class-based
views in general. IMHO one of the biggest uptake problems around
class-based views, and class-based generic views, is that there is a big
initial learning curve, and the reference docs are intimidating.

There is certainly room for improvement here -- either as a much improved
topic guide, or as a new tutorial. More docs and better docs is always a
good thing, and if someone wants to volunteer to write them, they get my
enthusiastic support.

Yours,
Russ Magee %-)

This is what I meant. Something that brings in, easy and clearly, the
concept of mixins, the different mixins,something that, for example,
take two mixins that alter the context, and combines them, stuff like
that, simple, but useful, and that gives you a glimpse of "real world"
usage and customization.

Couldn't agree more. If I understood class based views or Mixins
better, or had used them in a project, I'd do the docs. I still don't
understand a good use case for them. (All my projects have been small
enough to not need them...)

Intermittent mysql connection errors

[Guy]

I'm experiencing an annoying problem with a couple of django apps. Both 
apps are games built on Django that make regular calls to the db using 
python-db. We have error emails turned on, and every so often (the interval 
doesn't seem to follow a pattern but it's usually no more than once in a 
half-hour) we get an email with the following info (I've obscured/changed 
some identifying info, for the record):

The db connection works fine most of the time, it just seems like 
intermittently it can't connect. I've done a couple of things, like enabled 
tcp_tw_reuse (it seems I usually have about 150-200 connections to mysql in 
TIME_WAIT on any one web server), checked the mysql server and web servers 
message logs for too many connections errors, and looked at the mysql log 
to see if there's any info there. I also wrote a script that connects to 
the db and sends an email to me if it doesn't get expected info, initially 
I ran it with a cron job and didn't get any emails from it, but obviously 
that was only every minute. I'm now running it every second using the watch 
command but haven't so far had any emails.

It's very strange, and I'm not sure why it's happening. As I said, we have 
another django app (on completely separate infrastructure) that has the 
same issue. I don't believe there's a network issue but I wouldn't rule it 
out, but I'm curious if anyone else on here has seen this behaviour before, 
and if so, I'd like to know how you fixed it. Any help would be appreciated.

Thanks,

Guy

How does threading and processes work in Django

[dwang]

Hi,

I'm new to Django and need some help understanding how threading works in 
Django. I have some data that I'd like to recompute periodically in the 
background and have it shared between requests. If I start a thread in one 
of the view functions (e.g. my_thread.start()), would Django kill this 
thread at some point? What if I start the thread in the main function 
before entering the server loop?
Does Django handle each request in a separate process with its own 
interpreter instance?
Where can I find a good explanation of how thread management works in 
Django?

Any pointers would be greatly appreciated!
Danyao

[Rodrigo Morgado]

Hi everybody,

I'm new in Django framework. I installed version 1.3.1 over Python 2.7.3 in 
Ubuntu.
I already did all steps but i have an error when i execute python manage.py 
sql polls to create my table's project in mysql.

Traceback (most recent call last):
  File "manage.py", line 14, in 
execute_manager(settings)
  File

  File "/home/ewok/www/webapp_camposchilenos/polls/models.py", line 10, in 
Choice
poll = models.ForeingKey(Poll)
AttributeError: 'module' object has no attribute 'ForeingKey'

I checked my module and everything seems ok: 

  1 from django.db import models
  2 
  3 # Create your models here.
  4 
  5 class Poll(models.Model):
  6 question = models.CharField(max_length=200)
  7 pub_date = models.DateTimeField('date published')
  8 
  9 class Choice(models.Model):
 10 poll = models.ForeingKey(Poll)
 11 choice = models.CharField(max_length=200)
 12 votes = models.IntegerField()
 13 

Thank you for helping me.

Cheers,

Rodrigo

It's a subtle spelling error:
poll = models.ForeingKey(Poll)

should be

poll = models.ForeignKey(Poll)

Hi,

as Lachian said, It is spelling mistake for ForeignKey. Just correct your
word.
