Re: DatabaseRouter, add on runtime add new items to db.connections

[Anton Melser]

There appear to be relatively few references to this sort of thing peppered 
about the net, like this ancient stackoverflow 
post 
https://stackoverflow.com/questions/6585373/django-multiple-and-dynamic-databases,
 
the below email, or the now long abandoned db router mentioned below. 

Is there a "why this is completely unsupported and we won't answer any 
questions about it" post from one of the Django Masters somewhere? I also 
really want to do this... (actually am doing it but the dynamic dbs aren't 
managed by django, and I would really like them to be...). If it is a 
reasonable thing to do, is there some place with good advice on how to go 
about it? Thanks!

Re: Django Uploaded images not displayed in production

[Anton Nyagolov]

So guys I have found the problem. My Nginx server was only serving static 
files but not media ones, I have probably forgot about it. 
My Nginx settings were: 
The only thing I had to do is add a location for the media folder:


@MUGOYA DIHFAHSIH
At the begging of setting the server I also used apache2, it was pain in 
the ass and I switched to Nguix and Gunicorn. Setting the server over 
apache took me like 60-70 steps. With Nguix and Gunicorn it takes only 20 
steps, for 15 min you are all set up.
Watch this video and follow the guy: How to Deploy Python-Django serveer in

Re: Django Uploaded images not displayed in production

[Anton Nyagolov]

Thanks I will check out the group too for future reference and etc. Those 
images are uploaded to a database and are part of a model. I iterate 
through all the object and for each object I print some information 
including the images, therefore I cannot specify only one specific image. I 
use admin so I can add my (new future) projects and only by admin they 
should be able to display automatically on my website with all the 
information and structure required. 
Do you sugest changing the value of the imageField 
(upload_to="static//my_desired_path) ?

Django Uploaded images not displayed in production

[Anton Nyagolov]

Hello everyone, I just discovered this group through Google.I couldn't get 
any help on stack overflow and hopefully someone here can help. 

I have deployed a Django App on a Ubuntu server for the first time using 
Nginx and gunicorn. 
Before deployment, I used port 8000 to test if everything runs as it is 
supposed to and all was fine. Since I allowed 'Nginx Full' my database 
images are not showing up. 

This is my django project structure:



My virtual environment folder and my main project folder are both in the 
same directory. I have separated them. 

```python
# Create your models here.
class Project(models.Model):
project_name = models.CharField(max_length=120)
project_description = models.CharField(max_length=400)
project_link = models.CharField(max_length=500)
project_image = models.ImageField(upload_to='')

def __str__(self):
return self.project_name
``` 
I have set up my settings.py to :
```python
# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')


MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(os.path.dirname(__file__), '..', 
'media').replace('\\','/')
```

My view gets all the project object from a database and passes those to the 
template. The template renders successfully all other information related 
to project model except the image field . In my template I do: 
```html 
 

{% for project in projects %}
{% if forloop.counter|mod:2 == 0 %}

  {% else %}
  
{% endif %}



  {{ project.project_name }}
  {{ 
project.project_description}}
  Link


  

  {% if forloop.counter|mod:2 == 0 %}
  
  {% endif %}
  {% endfor%}

  
```
Uploading the images works, it sends them in the project's media directory, 
the problem is that they are not showing up, the alt="" is activated. 


My main urls.py: 
```python
urlpatterns = [
 path('', include('project.urls')),
path('admin/', admin.site.urls),
]  + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
```
The gunicorn system file:
```

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
User=myusername
Group=www-data
WorkingDirectory=/home/myusername/myproject
ExecStart=/home/myusername/venv/bin/gunicorn --access-logfile - --workers 3 
--bind unix:/home/myusername/myproject/myproject.sock 
myproject.wsgi:application

[Install]
WantedBy=multi-user.target

```
Nginx setup:
```
  server {
listen 80;
server_name  ;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /home/myusername/myproject;
}
location / {
include proxy_params;
proxy_pass 
http://unix:/home/myusername/myproject/myproject.sock;
}
}
```


EDIT: When inspecting the image element of the webpage the source of the 
image it is "/media/imageNmae.png". 
Any help would be appreciated!

Best option for wrapping a wsgi app

[Anton Melser]

Hi,

I searched high and low but my Google-foo must be lacking. I want to wrap a
wsgi app (https://github.com/tsudoko/anki-sync-server) and serve it under
my Django site. After wasting large amounts of time working around this
thinking it wasn't possible, I stumbled across
https://github.com/2degrees/django-wsgi, which does the trick nicely (at
least it appears to for what I need, though I have only tested locally).
Unfortunately, the last commit was 3-4 years ago, and it doesn't support
Django 1.10+ (is_authenticated() vs is_authenticated). I have submitted a
PR and am currently using a fork but the project appears completely dead.

What are other people using, if anything?

Cheers,
Anton

Re: Messages rejected?

[Anton Melser]

Thanks for the reply. I thought there might be a moderation queue (I never
made it as far as the dedicate list docs). I would be quite interested in
finding out what was inappropriate about my first attempt at posting and
what changed so that my second attempt (with a different email) was
acceptable. I would like to make sure any future questions I post to the
list are in the right form. Is that possible somehow, do you know?

Thanks.

Keeping/accessing the data Django generates during a test run

[Anton Melser]

Hi,

I can't work out whether it is expected or whether I am missing something. 
I would like to keep the DB data that I generate during a test run to 
inspect/persist it. --keepdb means I have empty tables at the end, 
strangely even if I ctrl-C a test run. It would also be logical for test 
data to get cleaned... Is there an option I can add to keep it?

I have a lot of calls to external services that should be mocked. The json 
returned from these calls is put in the DB as-is, so if I can just set up 
an initial run of the tests and then get the data from the DB that would be 
optimal. I could add file writes about the place to persist, but I want to 
evolve the test data over time and will need to do this often, so being 
able to do that from the DB would be very handy.

Any pointers?

Thanks,
Anton

How to operate with two models in one view

[Anton Smirnov]

There are two models "Sensors" with information about them and 
"Measurments" .

class Sensor(models.Model):
date_start = models.DateField()
Latitude =  models.DecimalField(max_digits=18, decimal_places=15)
Longitude = models.DecimalField(max_digits=18, decimal_places=15)

def __str__(self):
return 'id:%s / %s' % (self.id, self.date_start)
class Measurment(models.Model):
sens = models.ForeignKey(Sensor, on_delete=models.PROTECT)
time_of_measurment = models.DateTimeField()
humidity = models.PositiveSmallIntegerField()
temperature1 = models.DecimalField(max_digits=5, decimal_places=2)
temperature2 = models.DecimalField(max_digits=5, decimal_places=2)
temperature3 = models.DecimalField(max_digits=5, decimal_places=2)

def __str__(self):
return 'sens_id:%s, time:%s' % (self.sens.id, self.time_of_measurment)

>From each sensor I serially recive measurments. On the page, it is 
necessary to display the sensor data and the latest measurement data from 
the "Measurments" model corresponding for each sensor.

for displaying data about sensor I used ListView:

view:

from .models import Sensor, Measurmentclass SenorsListView(generic.ListView):
model = Sensor, Measurment
context_object_name = 'sensors_list'
template_name = 'sensors_list.html'
queryset = Sensor.objects.all().order_by('-date_start')

template "sensors_list.html":

{% extends "base_generic.html" %}{% block content %}
Sensors List
{% if sensors_list %}

  
ID sens
Date of install
Latitude
Longitude
Data from last measurments
  
  {% for sensor in sensors_list %}
  
{{sensor.id}}
{{sensor.date_start}}
   {{sensor.Latitude}}
{{sensor.Longitude}}
{{}}
  
  {% endfor %}

{% else %}
  There are no sensors in the DB.
{% endif %} {% endblock %}

But dont know How to display data about last measurments. I think need 
using aggregate to calculate max of time_of_measurment for each id_sens.

How it can be done?

You can try a module I made to avoid this particular issue in django

Re: How to replace content_type and object_id fields by a field with actual object in admin inline?

[Anton Ponomarenko]

Found solution.


Add form to admin.TabularInline:

class CriteriaPlacesInlineAdmin(admin.TabularInline):
model = PlacesToCriterias
form = CriteriaPlacesChoicesFieldForm  # <- ADDED FORM
class CriteriasAdmin(admin.ModelAdmin):
inlines = [CriteriaPlacesInlineAdmin]

admin.site.register(Criterias, CriteriasAdmin)


Form:

class CriteriaPlacesChoicesFieldForm(forms.ModelForm):
ct_place_type = ContentType.objects.get_for_model(PlaceTypesGroups)

object_id = forms.ModelChoiceField(PlaceTypesGroups.objects.all(), 
label='places')
content_type = forms.ModelChoiceField(ContentType.objects.all(), 
initial=ct_place_type, widget=forms.HiddenInput())

def clean_object_id(self):
return self.cleaned_data['object_id'].pk

def clean_content_type(self):
return self.ct_place_type

How to replace content_type and object_id fields by a field with actual object in admin inline?

[Anton Ponomarenko]

I have inline, which shows data of contenttype model, so instead of real 
objects, I see content_type and object_id fields. I can exclude these 
fields - this is not a problem, but also I want to get real current object 
as selected with other Places in a dropdown list. Could anyone tell me, how 
can I do this?


Model:

class Criterias(models.Model):
name = ...
class Places(models.Model):
name = ...
class PlacesToCriterias(models.Model):
content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
object_id = models.PositiveIntegerField()
content_object = GenericForeignKey()

criteria_group = models.ForeignKey(Criterias)

Admin:

class CriteriaPlacesInlineAdmin(admin.TabularInline):
model = PlacesToCriterias
class CriteriasAdmin(admin.ModelAdmin):
inlines = [CriteriaPlacesInlineAdmin]

admin.site.register(Criterias, CriteriasAdmin)

I can add to CriteriaPlacesInlineAdmin a form, something like:

class CriteriaPlacesChoicesFieldForm(forms.ModelForm):
places = forms.ModelChoiceField(PlaceTypesGroups.objects.all(), 
label='place')

but how can I pass\add object_id to this form\query in order to get 
'selected' place in the dropdown list?

Re: How to add\get data in admin via reversed relation using GenericTabularInline?

[Anton Ponomarenko]

It was quite easy. GenericTabularInline must be changed to 
admin.TabularInline


class CriteriaPlacesInlineAdmin(admin.TabularInline):
model = PlacesToCriterias
class CriteriasAdmin(admin.ModelAdmin):
inlines = [CriteriaPlacesInlineAdmin]

admin.site.register(Criterias, CriteriasAdmin)

How to add\get data in admin via reversed relation using GenericTabularInline?

[Anton Ponomarenko]

Hi all.

I can add Criterias to a place. How can I add Places to a criteria?

Models:

class Criterias(models.Model):
name = ...
class Places(models.Model):
name = ...
class PlacesToCriterias(models.Model):
content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
object_id = models.PositiveIntegerField()
content_object = GenericForeignKey()

criteria_group = models.ForeignKey(Criterias)

Admin - PLACES part:

class PlaceCriteriasInlineAdmin(GenericTabularInline):
model = PlacesToCriterias
class PlacesAdmin(admin.ModelAdmin):
inlines = [PlaceCriteriasInlineAdmin]

admin.site.register(Places, PlacesAdmin)

In this case, when I open Places admin change page, I can add Criterias items 
to my 'place'.

Admin - CRITERIAS part:

class CriteriaPlacesInlineAdmin(GenericTabularInline):
model = PlacesToCriterias
class CriteriasAdmin(admin.ModelAdmin):
inlines = [CriteriaPlacesInlineAdmin]

admin.site.register(Criterias, CriteriasAdmin)

In this case, when I open Criterias admin change page, I CAN NOT add Places 
item 
to my 'criteria', because instead of possible places I see criterias.

How to get Places items at Criterias admin page?
Thanks.

django-admin commands, diango 1.10 with python 2 & python 3 on windows installed

[anton]

Hi,

I am using django 1.10.1 with the following configuration:

- windows 7 64bit
- python 2.7.12 32 bit

Now I am switching to python 3 so I installed additionally
python 3.5.2 64 bit.

I still need to keep python 2 because I have
also trac (https://trac.edgewall.org) with mercurial
(https://www.mercurial-scm.org) installed both still needing python2.

Now my question:

 The windows PATH env variable contains python35 and python/scrips
 paths.

 With python 2.7 allone I could call on the console django
 admin-commands like:

>> manage.py showmigrations
or simply
>> manage.py
to see all commands

Now woth both pythons installed
>> manage.py
shows me all commands

But if I try to execute one command like

>> manage.py showmigrations

it does ... nothing, no error ... nothing.

If I call python like

>> python

on the command line the python 3.5.2 shell starts

The only way to make the django-admin commands work
is to call them like this:

>> py -3 manage.py showmigrations

Now it works.
( of course prepending the full python exe path works too
like
 >> c:\python35\python manage.py showmigrations )

Does somebody know the trick to use python 3.5 without the
need to use "py -3"?

Or is a simultanuously installation of python 2 and python 3 on windows
a no-go?

Thanks for a hint

 Anton

How to make properly choices based on two models?

[Anton Ponomarenko]

Hello.

I want to let users to choose their countries. I have 2 models = *Countries* 
with some figures and *CountriesTranslations*. I am trying to make tuple 
with *country* (because user has FK to this model) and its *translation*. 
In front-end I see dropdown list of countries, but when I try to save the 
form, I see error: *Exception Value: Cannot assign "'AF'": 
"UserProfile.country" must be a "Countries" instance.* Error happens at the 
line *if user_profile_form.is_valid():*

# admindivisions.models
class Countries(models.Model):
osm_id = models.IntegerField(db_index=True, null=True)
status = models.IntegerField()
population = models.IntegerField(null=True)

iso3166_1 = models.CharField(max_length=2, blank=True)
iso3166_1_a2 = models.CharField(max_length=2, blank=True)
iso3166_1_a3 = models.CharField(max_length=3, blank=True)

class Meta:
db_table = 'admindivisions_countries'
verbose_name = 'Country'
verbose_name_plural = 'Countries'


class CountriesTranslations(models.Model):
common_name = models.CharField(max_length=81, blank=True, db_index=True)
formal_name = models.CharField(max_length=100, blank=True)

country = models.ForeignKey(Countries, on_delete=models.CASCADE, 
verbose_name='Details of Country')
lang_group = models.ForeignKey(LanguagesGroups, on_delete=models.CASCADE
, verbose_name='Language of Country',
   null=True)

class Meta:
db_table = 'admindivisions_countries_translations'
verbose_name = 'Country Translation'
verbose_name_plural = 'Countries Translations'


# profiles.forms
class UserProfileForm(forms.ModelForm):

# PREPARE CHOICES
country_choices = ()
lang_group = Languages.objects.get(iso_code='en').group
for country in Countries.objects.filter(status=1):
eng_name = country.countriestranslations_set.filter(lang_group=
lang_group).first()
if eng_name:
country_choices += ((country, eng_name.common_name),)
country_choices = sorted(country_choices, key=lambda tup: tup[1])


country = forms.ChoiceField(choices=country_choices, required=False)

class Meta:
model = UserProfile()
fields = ('email', 'email_privacy',
  'profile_url',
  'first_name', 'last_name',
  'country',)


# profiles.views
def profile_settings(request):
if request.method == 'POST':
user_profile_form = UserProfileForm(request.POST, instance=request.
user)

if user_profile_form.is_valid():
user_profile_form.save()
messages.success(request, _('Your profile was successfully 
updated!'))

return redirect('settings')

else:
messages.error(request, _('Please correct the error below.'))

else:
user_profile_form = UserProfileForm(instance=request.user)

return render(request, 'profiles/profiles_settings.html', {
'user_profile_form': user_profile_form,
})

As I understand, *country* from *((country, eng_name.common_name),)* is 
converted to *str*. What is the right way to keep country instance in the 
form? or if I am doing it in the wrong way, what way is correct?

As a possible solution is to use *ModelChoiceField* with overriding 
*label_from_instance* as shown below:
class CountriesChoiceField(forms.ModelChoiceField):
def __init__(self, user_lang='en', *args, **kwargs):
super(CountriesChoiceField, self).__init__(*args, **kwargs)
self.user_lang = user_lang

def label_from_instance(self, obj):
return obj.countriestranslations_set.get(lang_group=self.user_lang)


class UserProfileForm(forms.ModelForm):
user_lang = user_lang_here
country = CountriesChoiceField(
queryset=Countries.objects.filter(
status=1, iso3166_1__isnull=False,
countriestranslations__lang_group=user_lang).order_by(
'countriestranslations__common_name'),
widget=forms.Select(), user_lang=user_lang)

class Meta:
model = UserProfile()
fields = ('email', 'email_privacy',
  'profile_url',
  'first_name', 'last_name',
  'country',)

but in this case there are too much queries because of the 
*label_from_instance* and page loads too slowly.
Would appreciate any advice how to solve this task.
Thanks.

Howto to create custom admin commands with subcommands

[anton]

Hi,

is there an possibility to use
https://docs.python.org/3/library/argparse.html#sub-commands

in the custom admin commands so I can have subcommands like

manage.py mycommand subcommand1 choice1-for-subcommand1
manage.py mycommand subcommand1 choice2-for-subcommand1
manage.py mycommand subcommand2 variable-param


Preferably an official way.

I tested an example which I found in the internet
(forgot where), it worked in python 2.7 but didn't in python 3.5
(even when using the same django 1.10 base)

Best way to switch from mysql to postgres?

[anton]

hi,

I have a django (1.8.13) project running
on windows 7 64 bit + python 2.7.10 (32bit).

Actually it runs with mysql (precise: mariadb)
and I tried the following:

1. commandline:> manage.py dumpdata -o dumpdata.json

2. then I switch the engine to postgres in my django settings file
  (the empty postgres is already prepared)

3. commandline:> manage.py loaddata dumpdata.json

Unfortunately it runs into an error.

Before I put here all the details, first one question:

Is this way supposed to work?

Or how would you do it?

Thanks

 Anton

Hi,

at home it works, but in my company
the proxy refuses the connection to:

https://www.djangoproject.com

and my firefox gives me an error:

ssl_error_inappropriate_fallback_alert

Question: since when did you switch the website to https
(or didn't I notice it)

Other sites seems to work, is there anything special
with https://www.djangoproject.com ?

All the time I had no problems.

If I don't use etag, and request method is HEAD then 200 is returned.

Some sites for checking 304 status (e.g. http://last-modified.com/en/ ) use

What is *the* django 1.7 IDE which is opensource & multiplattform

[anton]

Hi,

actually I use Aptana Studio 3.4.1 (http://www.aptana.com/)
to develop Django apps (on Windows and Linux).

What I (personally) need from an ide:
 1. ability to debug (python code)
 2. support for django templates
 3. support for django (start a new project, adding a django app)
 4. support for refactoring (like rename and so on)
 5. support for mercurial
 6. multi plattform (at least windows/linux)

Starting with *django 1.7*, aptana marks some line
as errors which are not errors (undefined variables from import ..)

Now I have the following problem:
 
 - I tried the actual aptana 3.6.0, but it is buggy and does not work
   (no idea if and when it will be fixed, the development
   speed is actually slow)

 - if I use eclipse + actual pydev 3.7.1 I have
   no support for *django templates*

 - all other ides like PyCharm are commercial (the free pycharm does
   not support django and django templates, only python)

Now the question: does somebody know a solution?

Thanks

 Anton

Bug in django admin: list_editable should be not editable if appear in readonly_fields

[Anton Danilchenko]

Hello dev team!

I think that if some field set to *readonly_fields* than we should display 
disabled field in *list_editable*.

Now I have set field "*price*" into *list_editable* and *readonly_fields*. 
And I see this field not editable in "change view" in admin panel, but I 
see it editable in "list view".

If field not editable - I should not edit this field in admin site. But, as 
I can see - I can edit this field in "list view", that creates some 
problems. Because it isn't what I wan to see.

Re: recommended fcgi way for django 1.6 on windows? Problems with https

[anton]

I also looked at nginx which is quite nice,

but now I found the mod_authn_ntlm SSPI win32 module
for apache

   http://www.apachelounge.com/viewtopic.php?p=25073 

which finally alows me to do SingleSigneOn  on windows,
and it works :-)

for nginx I did not find such a module 
(I saw something outdated somewhere)

But you are right  nginx is nice too

Re: recommended fcgi way for django 1.6 on windows? Problems with https

[anton]

Hi

I did a test with modwsgi on windows with apache,
http and https work now both.

Thanks :-)

*BUT*: the modwsgi does not support Daemonmode on windows,
which means that I need to restart the whole apache Server every time
I update my django app.

For a real productionserver its a nightmare, if there are different apps
hosted.

Perhaps I find a solution .. :-(

Hi Russ,

thanks for the advise, I didn't know that fcgi is deprecated.
I thought its nicer to use so I can have different 
apps ( = parts of my web intranet portal) running as
 - complete independent django instances
 - with different ( = independent) databases 

So if I have to do some more critical changes in one part of my
web portal I can shutdown only the one fcgi service do the work
and start it later again.

-> the rest of the services are not touched.

I am not sure if this is possible with wsgi.

I use apache 2.4.9 on windows with the modwsgi 
but I am unsure about the modwsgi for apache
(http://code.google.com/p/modwsgi/)
because the last code change is from october 2012
so it seems a little bit "abandonware".

(I looked at uwsgi, but it runs only on Linux/unix)

Is there any (even "semi") official best way to run django on windows
(which is up to date)?

Or is windows officially not supported for production?

Thanks

 Anton

recommended fcgi way for django 1.6 on windows? Problems with https

[anton]

Hi ,

I use:
 - windows 7 64 bit
 - python 2.7.6 (32bit)
 - apache 2.4.9 (32bit vc9 build from apachelounge) 
 - django 1.6.2
 - flup for fcgi ( noted as prerequisite in django docs)

I use flup for running django as fcgi,
unfortunately I have the problem that
my django app runs fine with http but not with https.

I saw that in https mode the request.path
variable in my view is not '/mydjangoapp/' (like in http mode)
but '/mydjangoapp/mydiangoapp/'.

So the links which are calculated with the reverse("myapp.myview") function
are wrong.

I looked a bit in flup bit did not fully understan why it builds the
request.path variable the way it does (add least in https mode 
the apache does not create a SCRIPT_URL = the env["SCRIPT_URL"] in flup
is empty, and this seems to cause the problem).

my questions are now:
 - Is there any special point to take care about when using https?
 - is there another reccomended way to do fcgi (on windows)??

I ask this because flup seems *dead*, and the flup website 
is down since *months* now (at least it was down every time I tried to
access the flup trac).

So what is the future for django and fcgi on windows,
or will this functionality be integrated in django 1.7 (would be nice).

Thanks

  anton

Question about Django & Msyql-python for windows

[anton]

Hi,

I am using Django 1.6.2 with:
 - python 2.7.6
 - mysql-python-1.2.3 
 - and mysql 5.5.36)
on windows 7 64 bit.

I just saw that there is a MySQL-python-1.2.5.win32-py2.7.exe
on https://pypi.python.org/pypi/MySQL-python/1.2.5

I tried it out but stumbled over the fact that the 
mysql connection over named pipes seems to be broken.
(via tcp port 3306 it works).

In the past I did a try to the 1.2.4 version but it did not work either 
(do not remember exaclty what)

Since the mysql-python project seems to move quite slowly (no python 3.x)
my question is:

 - is this the only way to run django & mysql on *windows*
   or are there alternatives

 - is mysql support on windows a bit deprecated?

Thanks

 anton

Fixture extraction

[Anton Pirker]

Hello!

I have a fairly large production database (about 40GB) and I want to
extract a sample of it as fixtures so I can use this sample for
development.

The optimal solution would be that I can give a number of auth_users to a
script, and it will extract all data neccessary to have a complete set of
data for the given users.

A plus would be, if the email addresses of the users would be anonymized
and the password would be set to some default password.

Has anybody used any of the fixture packages [1] available?
Can anybody recommend a package, or an approach on how to do this?

Thanks in advance,
Anton

The problem is the amount of choice. There seem to be many great packages 
there but I was hoping someone from the community with more intimate 
knowledge of what is there might be able to shed some light on the subject.

CMS base to start with?

[Anton Melser]

Hi,

I'm pretty new to Django/Python and I'm starting a fairly major project 
(hopefully next 2+ years of my life :-)). If all goes well, there will be 
several developers on the project in a year or two - getting our hands 
dirty is what it's all about. Use something I know? PHP/.NET/Java - no 
thanks! It's going to be a long road and I've quickly seen the superiority 
of Python and the ease of development with Django and I'm definitely in for 
the long haul so... 

There is quite a bit of functionality that has been written 50k times 
before and I'd rather not reinvent, like advanced user management (social 
everything yadda yadda), some nice templates to start with (supporting 
bootstrap 3 within the next 2-3 months or so) and dynamic theming, blog, 
article management, easy plugging to search backends, content and user 
rating, unit tests, etc.

Beta versions are fine as long as the latest sexy version will go stable 
within 2-3 months and contributing back is a given, at least while it 
remains viable.

So I've been looking around at what to start with and there is quite a bit 
of choice. Django-CMS, Mezzanine, FeinCMS to name but a few... 

The stuff I refer to above is stuff I would REALLY like to have out of the 
box (ie, it's what we're starting with), for the rest (marketplace, 
mapping, geo-location, kitchen sink, etc.) we just need for it to be easy 
to add new modules which by then I/we should be able to write from scratch 
anyway, if needed. Other stuff we probably don't need at all like 
multi-lang.

I guess the only other particularity is that we are going to need excellent 
caching - we are expecting around 90% of the traffic on 2-3 days and 
serious peaking within that. Going PAAS is not out of the question but if 
we can get away with some advanced caching then I'd rather start with that 
and then if cashflow warrants it re-evaluate the situation later. 

So, should I start with a CMS? If so, which one? What I'm really looking 
for is a base to start with that I don't end up saying "why the #!@& did I 
start with X" in 12 months time...

Any opinions or insults are most welcome!

Thanks,
Anton

Django Meeting in Vienna, Austria!

[Anton Pirker]

Hello fellow Djangonauts and Djangonistas!

This message is especially for Django developers and friends from Austria.

At the last two DjangoCons in Europe a few people from Austria got to know
each other and at last years conference in Warsaw we spontaneously founded
the Django Friends of Austria. (The only activity until now was standing
around in a group between talks at DjangoCircus in Warsaw and twaddle...)

But now Stephan, a friend of mine is planning a real Django Meetup in
Vienna! Yay!

So if you are into Django and want to meet other Djangonauts and
Djangonistats in Vienna head over to this Doodle and tell us, when you have
to time to meet: http://doodle.com/2hs77khscrkuc4ba

Depending of how many people sign up the meeting will be held in WerkzeugH
[1] or at Sektor 5 [2]. The first meeting should be more like a 'getting to
know each other' event, so there are no big talks planned at the moment. At
the meeting we can decide how the meetings should be in the future.

Looking forward in meeting you!

Bye,
Anton

Re: Right way to modify contrib auth package?

[Anton Baklanov]

Hi.

I think that subclassing PasswordChangeForm and doing password length check
in child's clean method is more "correct" way to do this.

Note that contrib.auth's views accept form class as parameter (
https://github.com/django/django/password_resetblob/master/django/contrib/auth/views.py#L242<https://github.com/django/django/blob/master/django/contrib/auth/views.py#L242>),
so you can pass your custom form class to view at urls.py, like that:

url(r'^/url/$', view, {'password_change_form': CustomPasswordResetForm})

Re:

[Anton Parkhomenko]

Actually, I don't think that any of Django-based CMS' (mezzazine, 
django-cms or feincms) is something like drupal or wordpress. Anyway you 
need to know django or python at some level, because there isn't plenty of 
ready-to-use themes and plugins. You always need to develop some parts by 
yourself.

Django IO exceptions through times

[Anton Parkhomenko]

Hi.
I have a strange problem with Django. It raise exceptions like 
TemplateDoesNotExist or ImportError, while actually files and modules are 
exists and have proper rights. This error appears not everytime, but in 
~1/20 cases (not regular), thus I thought about to blame my VDS, but other 
projects with older software works correct on this server.
On this project I'm using Django 1.4.4, django-CMS 2.4.0-RC1 and uWSGI 
1.2.6 (for all other projects) with virtualenvs.
How do you think, what's the problem?
P.S. There's a not small set of "lost" files. They're all the same almost 
each time, only 6-8 of templates and modules.

Re: Impossible? Django with NTLM SSO auth on windows?

[Anton]

Hmmm

the bad support (as you mention "it hasn't been updated in quite some time")
seems to be a major problem in this domain.

I just looked at (for apache)
http://mod-auth-sspi.sourceforge.net/docu/mod_ntlm/

Here they say mod_ntlm is obsolete and 
" mod_auth_sspi is the version of mod_ntlm for Apache-2.0"

but on the other side mod_auth_sspi seems to be dead too,
so actually I am still not sure if its possible,
if you don't want to use pure Microsoft technologies 
(like asp.net IIS server & other tools from ms)

I am looking ..

@Branko,

no...I didn't think about Kerberos, I only realised
in the last day that Ad use this system which I don't know either)

Do you know some tutorial/howto describing this SSO

with Django/apache on windows?

Or I am the only one on this planet with this ides?

Impossible? Django with NTLM SSO auth on windows?

[Anton]

Hi,

I am using my django in the following way:

OS: Windows 7 (64 bit)

 + Python 2.7.3 (32bit)

 + apache 2.4.3 (32 bit) from apachelounge 
   (I use the version which was build with vs2008 like python 2.7.3)
http://www.apachelounge.com/download/win32/binaries/httpd-2.4.3-win32-
VC9.zip

 + django 1.4.5 

 + mod_wsgi 3.4 (32 bit) from http://code.google.com/p/modwsgi/
   (compiled manually with vs2008 since no binaries available)
 
I would like to use the typical Windows intranet scenario
where you have a single-sign-on with the internet explorer.

At least in our company the ASP .NET powered intranet sites
work fine with this.

I googled around, as if I understood right, this auth system
is called NTLM and if you want to use it, you need
the apache module "mod-auth-sspi".

If I look at the project page
http://sourceforge.net/projects/mod-auth-sspi/?source=dlp
I see only stuff dated from 2011 and only for *apache 2.2*. 

And if I read this article on apachelounge:

http://www.apachelounge.com/viewtopic.php?t=4548

then there will be *never* a support for Apache 2.4.

In the Django docs:
"Authentication using REMOTE_USER"
https://docs.djangoproject.com/en/1.4/howto/auth-remote-user/

you get links to mod_auth_sspi but its has be forgotten to mention
that this module (seems) now obsolete.

So the question is:

Is it possible to obtain SSO with Django on a Windows powered machine,
or do I have to give up and try my luck with ASP.NET or perhaps php for 
windows or whatever.

I love Django & python, but I am here in a dead end.

Is there somebody using this scenarion (which is quit common in big 
companies)?

Thanks.
Anton

No need for that. I've reproduced your problem. With python 3 __unicode__
method is ignored.

We should search for corresponding ticket on trac, or create new one.

 - django 1.4.2

If use my internet explorer in my company,
it does an automatic login on some services.

Is there a possibilty to:
 - add an user named "john" to my django
 - if john goes to my django app with his
   internet explorer:
   to check that he is john and authenticated
   (without to need the knowledge of his
windows password)?

Any hint would be helpful :-)

Re: How to implement a form to update the quantity?

[Anton Baklanov]

Hi!

You can use something like:

{% for item in garage.garagecar_set.all %}
Car:  {{item.car.name}}
Price:{{item.car.price}}
Quantity: {{item.quantity}}
ID:   {{item.car.id}}

  {{form.q}}
  

 {% endfor %}

and view like

def update_q(request, garagecar_id):
# get garagecar by id here, create form from request, set new value, save()


it to submit forms with ajax, to not reload entire page every time.


P.S.

it looks you are implementing Many-to-Many-Through relation. Django
has support for it out of the box

Re: How many attempts to generate a unique ID?

[Anton Popovine]

Yes it needs to be short. This will be an invitation string most likely 
written on a chalk board for kids.

Also there was an error in my initial post : I forgot to increment size += 
1 inside the while loop. Noticed right after posting.

thanks

How many attempts to generate a unique ID?

[Anton Popovine]

Hi everyone! First time posting to this group!

I have a model Class where each row has a unique alphanumeric ID string 
like 'EX39H'.

This is the function I use to generate the code.

def gen_class_code():
  import string
  import random
  size = 5
  max_size = 16
  attempts = 1000
  chars = string.ascii_uppercase + string.digits 

  # lets try  times to generate unique id, else increase code 
length
  res = ""
  while (size <= max_size):
for i in range(attempts):
  temp = ''.join(random.choice(chars) for i in range(size)) 
  if not Class.objects.filter(code=temp).exists():
res = temp
break
if res : break

  return res 

How much would you set the attempts variable to and why?

Thanks in advance
Anton

Re: Django development running on 127.0.0.1:8000 not accessible from same machine

oh, i misunderstood your question.

try to type url with schema into browser's address bar. i mean, use '
http://localhost:8000/' instead of 'localhost:8000'.
also it's possible that some browser extension does this, try disabling

Re: Django development running on 127.0.0.1:8000 not accessible from same machine

[Anton Baklanov]

try running dev server with command like "./manage.py runserver 0.0.0.0:8000"
- 0.0.0.0 means that socket will listen for connections on all interfaces.
other people in your network will be able to connect your box using your ip.

if this does not help - show us output of 'sudo iptables-save' and 'sudo
ifconfig'

Re: skip fixtures loading on 'manage.py test myapp'

Hi Melvyn!

Just tested it on dummy project, and you are right - django itself does not
do anything like that.
Problem is in South - when i remove it from INSTALLED_APPS 'manage.py test
myapp' does not load any fixtures except 'initial_data'.

So, i'm going to south sources now.

Thanks!

skip fixtures loading on 'manage.py test myapp'

[Anton Baklanov]

Hi!

When I'm running 'manage.py test myapp' it loads all fixtures that are in
'myapp/fixtures' directory.
And what I want is to find a way to tell django skip this fixtures and
instead load some other ones or maybe no fixtures at all for certain tests.
Is it possible?

Re: login or login_decorator issue

[Anton Baklanov]

1) i can't see in your code where you are creating some kind of session and
set some cookies to save auth state between requests.
2) is it login_required from django.contrib.auth? if yes - use login from
django.conrib.auth or create your own decorator to check user auth.

anyway - django provides ready for use user auth mechanism and maybe it's
better to use it https://docs.djangoproject.com/en/dev/topics/auth/

yes, you need to add field and I'm guessing that ModelChoiceField will work
for you.
https://docs.djangoproject.com/en/dev/ref/forms/fields/#modelchoic
efield<https://docs.djangoproject.com/en/dev/ref/forms/fields/#modelchoicefield>

looks like you are using some additional layer before django.forms and
don't just create fields directly, so you may need to extend it too.

object.create speed, creating 3 objects takes 1 sec in sqlite

[Anton]

Hi I am new to Django.

I worked through the tutorial.

I created a small test app on:
 - Win7 64bit
 - python 2.7.3 (32bit)
 - Django 1.4.1
 - using the development server
 

Now I wanted to populate the (sqlite backend) database
with a python script.

My Problem:

I Insert 3 Object (like MyModel.objects.create(name="..", comment="..") ).

They consts only of 2 strings.

Inserting these 3 items take roughly 1 sec.

In settings.py I set DEBUG = False, but this doesnt help much
(I readed something about this on the net).

I retried with the mysql backend:
 -  mysql 5.5.27 (64bit)
 - using sockets (named pipe on windows)

Now the time varies between 0.2 sec and 0.8 sec every time
I insert suche a 3 object tripplet.


My Problem: I will populate it with 5 items.

Has Django really such a bad performance for data insertion?

I can't believe it, so ... can somebody give me a hint?
Is there a doc page dedicated to speed/performance issues??

Otherwise I have to look for an other system.

Thanks 

Anton

Re: combobox prepopulated to only related objects to "self"

[Anton Baklanov]

you can try something like that:

group = ...
choices = [(product.pk, product.name) for product in
group.product_set.all()]
form.fields["myfield"].choices = choices

Re: Django-utils @async decorator and gunicorn

another thing I don't know about is gunicorn; but the 'g' in the name

"g" stands for green unicorn. and we use gevent with gunicorn. so it 
could be that there is a problem with the threading implementation..

OTOH, now that you have the daemon running, maybe it would be easier
to use the djutils task queue.  try changing the @async with
@queue_command (found in djutils.queue.decorators)


i have tried this, but it resulted in an strange error.

i think i will skip the asynchronous stuff from djutils. tomorrow i will 
install celery [1] and try my luck with that. :)

Ah! There is a queue consumer daemon! ;)  Thank's for this hint!

I have now the queue consumer configured in my supervisord.conf like this:

[program:preview_queue_consumer]
environment=PYTHONPATH="/home/preview/.virtualenvs/preview/source/myproject/:/home/preview/.virtualenvs/preview/lib/python2.6/site-packages/djutils/:$PYTHONPATH"
directory=/home/preview/source/myproject/
command=python manage.py queue_consumer --settings=myproject.settings -l 
logs/queue_consumer.log --verbosity=2 -t 2

user=preview
autostart=true
autorestart=true


when i start the daemon the logs says this:

delay: 0.1
backoff: 1.15
threads: 2
2011-06-28 09:18:06,329:djutils.queue.logger:INFO:Loaded classes:

so i assume the daemon is started.

but when i run my @async function nothing happens. in the log output 
above i can see that QueueCommand and PeriodicQueueCommand are loaded.
can it be, that the consumer can only consume this sort of functions and 
not functions with @async?


i tried to add the @queue_command instead of the @async to my function, 
but then i get the error:

"can't pickle StringO objects"
and i do not have a clue what this means. (maybe it's my lack of english 
skills, but what should 'pickle' in this context mean?)



anyone an idea or hint where i should look next, to get my @async 
functions running in gunicorn?


thank's in advance,
Anton

Django-utils @async decorator and gunicorn

[Anton Pirker]

Hello! 

I use djutils [1] @async decorator for calling a function asynchronous. This 
works well when i start my server with the standard ./manage.py runserver 
command. But when i run my django app under gunicorn and i call the function 
with the @async decorator nothing happens at all... 

Do i have to configure djutils or gunicorn in a special way so i can run 
function asynchronous? 

Any hints are greatly appreciated! 

Thank's

Re: Our new startup site build on Django and GAE is now live!

If you use something like Firebug you can remove the blur layer and have a

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[Anton Danilchenko]

Now I have next solution (but still need your help).

1) I have added to my form custom field CharField for render field as
input 

2) I have created Form method clean_phones() for check all values is
valid

3) in views.py I have get field contents, split it by comma and delete
all non-numbers. In result I have list of phones in format 01234567

4) in views.py I create Phone model record for each phone
phones = ['01234567', '45678921']
ids = []
for phone in phones:
  ids.append(Phone.objects.get_or_create(number=phone))

5) pass ids to real form field - ManyToManyField called phones


Please, help me understand how to pass all this logic in one place -
in custom field.

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[Anton Danilchenko]

Thanks. I have read this article.

In my Form I have added validation for check phone numbers. All right
- I show user error message if given incorrect phone number. This is
simple.

I need to save this phone numbers  in model Phone if all phone numbers
valid and all other fields in this form is valid. If one of the fields
in this form is incorrect I don't save any phone in Phone model.

As I see, ManyToManyField need get list of Phone IDs. But, actually I
have only full phone numbers in format 01234567. I need to get ID for
each phone (or create new record in table Phone). After this I need to
get list of Phone IDs and pass this data to ManyToManyField.

How can I do this? Thanks.

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[Anton Danilchenko]

Message - this is a rental proposition (rooms, floor, cost, area,
country, cirty and contact phones).

Visitors can create new messages (message - this is a rent
proposition) and enter list of own phones (one or more phones). My
application store this phones not in char field, but save each phone
number to separate Phone morel - one phone in one model). If phone
already exists - message attached to this phone. If phone not exists -
we create new phone and attach message to this phone number.

In future, I tell to people - and see that this people not a good
man :-). I go to my application and mark this phone number to black
list. All future messages from this people to be marked as bad
messages.

Now I need to create own Form field called MultiPhoneField based on
CharField widget, but implenet logic of ManyToManyField. I need show
for user CharField where user enter comma separated phone numbers. I
check this numbers and if all numbers correct - store this numbers in
database in Phone model (each phone in separate record) and associate
message with list of this phones.

Can you please help me in this. I not understand how to create my own

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[Anton Danilchenko]

I describe my task more reallistical.

This is application for rent an apartment. User can create new message
with information about apartment, and also add one or more contact
phone numbers. One user, without registration, can create more that
one message on the site. For one message can add one phone number, for
other message add two phones.

I need to save only one copy of phone number in database in format
. For each phone I can set if this phone in black list or not
(model Phone have property "blocked" by default setted to False).

I want to save phone numbers in model Phone, and messages in model
Message. But, people can see input text field (CharField) where enter
one or more phone numbers separated by comma.

class Phone(models.Model):
  number = models.CharField(max_length=20)
  blocked = models.BooleanField(default=False)

class Message(models.Model):
  # ... information about count of rooms, floor, cost, etc ...
  phones = models.ManyToManyField(Phone)


Nick, thank you for you help. You are really very good people!

Re: ManyToManyField to Phones model for enter phones manually (not select from list)

[Anton Danilchenko]

In my case, I have Users with equal phone numbers. And I need only
ManyToMany relationship.

I need create custom field for get information from CharFiels,
validate this data, clean and save to datastore in separate model. If
this phone already exists - we get ID of this phone. And, if this is a
new phone number - we insert this phone to separate model and get new
ID.

ManyToManyField to Phones model for enter phones manually (not select from list)

[Anton Danilchenko]

Hi all!

Please, help me undestand, how to solve next task.

I am show for user form with two fields: user name and text field,
where user input list of phones, separated by comma. User sholud enter
one or more phones separated by comma. If user enter not valid number
- we show error message like this "Phone 12345 is not valid. Please,
enter valid phone numbers separated by comma".

I have next two models:

class Phone(models.Model):
  number = models.CharField(max_length=20)

class UserInfo(models.Model):
  name = models.CharField(max_length=70)
  phones = models.ManyToManyField(Phone)

User should enter numbers in CharField in format 0XX XXX . But, I
need save phone in database in format 0XX (only number without
spaces and other non-numbers digits).

Please, can you help me in this. I am new in Django, and I am read
more articles and not found solution. I think that I need create
custom fields for form and model.

P.S. Also, in admin section I should see CharField instead of
ManyToManyField.

Re: Spam filters for Django?

[Anton Bessonov]

the three most common ways are to only allow logged in users to post,
captchas or akismet or a combination of the three.
  

Sometimes Honey pot is very effective in combination with captcha.

Re: Мобильная версия

[Anton Bessonov]

Де факто - Вам не нужен полный список. Но если так хочется, то 
достаточно инициально поддерживать список самых распростанённых агентов 
и сделать ссылки "нормальная/мобильная версия". Каждый клик 
протоколировать и из этой информации модифицировать список.

Спасибо за перевод моего вопроса, но тут дело в том, что я уже видел
эту страницу, и список там далеко не полный, и тем более, список этот
постоянно пополняется, с выходом новых ОС для мобильников.
Как реализовать универсальный проверку? Создать свой словарь из кусков
возможных User Agent'ов без использования цифр версий ОС и тд и
проверять его вхождение в полученный User Agent зашедшего на сайт
пользователя?

Re: Install Django in a Production server!

[Anton Bessonov]

Using Django on Apache with mod_python in production - it's a bad idea! 
wsgi or fcgi is better start point.

If I understand, you want information about installing python/django in

I recently do this on a Linode Virtual Ubuntu Server and I think you can
do the same.

Here a tutorial: http://library.linode.com/web-frameworks/django

I'm not a Linode man! What you find on this tutorial you can apply on
other virtual / phisical server, but I found Linode a good choice for
me: http://www.swap-hq.com (only italian - sorry!!).

django & wsgi: what is the preferred webserver?

[anton]

Hi,

I am new to django and wanted to set up a webserver
and use apache or lighttpd.

As I understood wsgi is the preffered ( most performant) way
to use python & a web server.

I heard that apache has a mod_wsgi and wanted to ask if 
there exists such a module for lighttpd too?

What would you propose to use:
 - apache + mod_wsgi
 - or lighttpd + ??

Anton
