Re: Help with Custom model field and Custom validation for EmailField().

[Dilip M]

Hi Chris,

Thank you very much for your time on this. I am not able to make out on how
could I put this under clean() method. Ex: What does "you must call
the*parent class's clean()
"* mean in "if you would like to override the clean() method and maintain
the _default validation_, you must call the parent class's clean() method."

This clean() method will go in models.py? or forms.py? Any simple examples
would be of great help!

Many thanks...Dilip

Re: Help with Custom model field and Custom validation for EmailField().

[Chris Pagnutti]

I've never done it myself, but I think you'd just define the clean method
in your Form's class (i.e. in forms.py), and the first line in your clean()
method should call the parent classes, clean() method - to do this you need
to call the super() method, which is just regular python.  It think the
call would look something like this

super(YourFormClass,self).clean()

Tutorial Help!

[almel]

I'm new to Django and trying out the tutorial and almost immediately 
getting stuck. I'm running django version 1.5, python version 2.7.2, and 
windows 7, and when I type into the command prompt 

django-admin.py startproject mysite

(I can't get rid of this green blob) The command runs, but it doesn't return 
anything. Any help, I'm sorry it's so vague but I don't know what's going on.

Django and HSQLDB

[Abracadab]

Hi, all. I'm building a Django app against a legacy HSQLDB database
(the existing user interface is built in OpenOffice Base). Is there a
way to use HSQLDB with Django? Alternatively, does anyone know if
there's a way to easily alter the existing database to any of the
existing Django/SQL interfaces?

Thank you,

Want help in Django basic configuration

[sudeep gangal]

hey guys hiii,
I am new to the django. I used the inspectdb command to copy the content of 
my db table made in mysql in django model.py. But that file doesn't contain 
any foreign key etc. 
I have declared primary keys and unique keys. But for relating 2 tables a 
foreign key is required. Can anyone suggest me a solution to the above 
defined problem

selenium test for fallback page loaded from app cache when server is unavailable

[Joao Coelho]

Hi. I haven't been able to figure this one out. Trying to write an 
automated test that uses selenium.webdriver.firefox.webdriver

The manifest file has
FALLBACK:
/online.html /offline.html

So that at /online.html the browser displays the cached copy of 
/offline.html when the server is offline

Also, to simulate server unavailable for testing
/online.html returns a 200 response
/online.html?offline=1 returns 503

This all works fine when I browse manually
/online.html displays "I am online"
/online.html?offline=1 displays "I am a cached page"

I want the selenium test to get /online.html?offline=1 and see "I am a 
cached page" /offline.html
But it's only showing a blank page
I think it's stopping at the 503 and not loading from the app cache

def test_offline(self):
"""Simulate site being offline"""
self.selenium.get('%s%s' % (self.live_server_url, 
'/online.html?offline=1'))
self.assertIn('cached page', self.selenium.page_source)

How can I make it test this? Thanks.

What are you expecting it to return? It's not expected to actually return 
anything, but it sets up your project folders.

inspectdb is a best guess. It can't necessarily tell the difference between 
an IntegerField and a ForeignKey. But you can just change the generated 
code accordingly.

mysql slow query flooded with set timestamp = ; commit

[Yanhong Wu]

I'm using django 1.3, recently I found  mysql slow query log was flooded by 
the following query:


# User@Host: user[user] @  [192.168.1.10]
# Thread_id: 2948369  Schema: db  Last_errno: 0  Killed: 0
# Query_time: 6.705106  Lock_time: 0.00  Rows_sent: 0  Rows_examined: 0

# Bytes_sent: 11  Tmp_tables: 0  Tmp_disk_tables: 0  Tmp_table_sizes: 0
SET timestamp=1351951740;
commit;

There're several commits in every second, and each commit takes more than 5 
seconds.

Thanks,

django1.5 subclass AbstractUser, How to get a password-(re)set field in admin

[Michael Muster]

Hi again,

I have a subclass from AbstractUser

1 from django.contrib.auth.models import AbstractUser
2 from django.conf import settings
3
4 class cpUser(AbstractUser):
5 twitter = models.CharField(max_length=100)
6 def __unicode__(self):
7 return self.username

and 
AUTH_USER_MODEL = 'account.cpUser'
in my settings.py set.

How do i get a password field to set and reset
a password in my admin app?
Adding the password field to admin.py does obviously not
work as it enters plain text and not the hashed password.

1 from django.contrib import admin
2 class cpUserAdmin(admin.ModelAdmin):
3fields = ['twitter','username', 'first_name', 'last_name', 'password',]
4
5 admin.site.register(cpUser, cpUserAdmin)


Do i have to set a passwort field to the models.py or
can i geht that from the models which i "abstracted" from
(as done with username, first_name, last_name...)



Best regards
Michael

Re: selenium test for fallback page loaded from app cache when server is unavailable

[Brad Pitcher]

Are you having the selenium test go to online.html first like in your
manual test?
Maybe you need to have selenium hit offline.html first and cache that page?

Re: GeometryField.geography = True Syntax Help GIS Model

[JJ Zolper]

Thanks for the reply.

I actually already have PostgreSQL.

So my question was pretty direct, or so I thought.

I'll try and spell this out again. So if I want to create a column in my 
database with type "geography" is this the syntax:

mpoly = models.MultiPolygonField(geography=true)

I cannot find an single example where we specify that we want the geography 
type to be used instead of using geometries.

All I need to know is if that is right? Is it a capitalized "true" so 
"TRUE" ?

Thanks so much,

JJ

I have used hsqldb in some of my projects alas not with django. It is
possible that you could fire up the hsqldb in server  mode with a command
like this

java -cp ./lib/hsqldb.jar org.hsqldb.Server -database.0 file:mydb -dbname.0
xdb

and then use the tool in odred to browse the database.

java -cp ./lib/hsqldb.jar org.hsqldb.util.DatabaseManagerSwing

after that, you can issue any sql command you like to export the database...

https://docs.djangoproject.com/en/dev/topics/auth/#custom-users-and-django-contrib-admin

The key is that you can't just subclass admin.ModelAdmin -- you need to
subclass the existing Django admin class for Users
(django.contrib.auth.admin.UserAdmin) - that base class is what provides
all the special password handling etc for User models.

databases.

Unfortunately, I'm not aware of any existing project to build a HSQLDB
backend for Django.

Re: tutorial first step. -ImportError: No module named django.core-

[Elena Williams]

Hi Francesco,

What you're seeing is the most basic django/python error. It means that
your python can't find django from your current path.

You should start by checking for the simple things.

What happens when you try putting the following in your terminal?:
$ python

and then:
>>> import django

Also where is your django-admin.py file located?

Elena :)

Location of non-app-specific static files?

[Ryan]

Hi,

I have been wondering where people put their non-app-specific static files 
in their django projects?  For example, the base css file that applies to 
all pages across the project or perhaps the jquery file?

Currently I have the following structure:

.
├── app
│   ├── __init__.py
│   ├── models.py
│   ├── static
│   │   └── app
│   │   ├── css
│   │   ├── img
│   │   └── js
│   ├── templates
│   │   └── app
│   ├── tests.py
│   └── views.py
├── manage.py
└── mysite
├── __init__.py
├── settings.py
├── static
├── templates
├── urls.py
└── wsgi.py

My STATIC_ROOT setting points to the ./mysite/static directory as this is 
where I would like collectstatic to dump all the static files for 
deployment, however this is also the obvious place (for me anyway) to place 
non-app-specific static files as they apply to the project as a whole like 
the templates directory at this level.

Does any one have any input on this?

Thanks,

Ryan

Hi Ryan,

I'm not sure if it helps but not long ago I found this by Simon Willison on
Quora:
http://www.quora.com/Django/How-do-you-organize-the-code-in-your-Django-project

Cheers,
Elena :)

RE: Help with Custom model field and custom validation for EmailField()

[bb6xt]

Hi,
If all u nid is a field whose value is a comma separated list of emails den u 
dont nid a custom field at all. All u nid is a gud ol CharField. Just set it 
like so:
emails=models.CharField(max_length=500, validators=[multi_email_validator,]).
here is what multi_email_validator looks like:
from django.core.validators import EmailValidator
from django.core.exceptions import ValidationError
def multi_email_validator(value):
if value and "," in value:
for v in value.split(",").strip():
try:
EmailValidator().__call__(v)
except: raise ValidationError("%s is not a valid email" % v)
else:
try:
EmailValidator().__call__(value)
except: raise ValidationError("%s is not a valid email" % value)
with dis aproach and using modelforms u dont nid to validate in forms or views 
cos calling form.is_valid with call model field validators too. Hope dis helps.
abraham.
