Re: ORM, Oracle and UTF-8 encoding problem.

[Jani Tiainen]

Tested against latest master. Same behaviour.

In Oracle backend base.py is following piece of code:

# Check whether cx_Oracle was compiled with the WITH_UNICODE option. 
This will

# also be True in Python 3.0.
if int(Database.version.split('.', 1)[0]) >= 5 and not hasattr(Database, 
'UNICODE'):

convert_unicode = force_text
else:
convert_unicode = force_bytes

Which was added in 

Thing is that my cx_Oracle is version 5.1.2, it has cx_Oracle.UNICODE 
definition.


And Django uses smart_str / force_bytes.

If I remove that and use convert_unicode as force_text / force_unicode 
everything works as expected.

This does pass on Oracle when using Django's master branch, both with
Python 2.7 and 3.3.

Django's backend is doing all sorts of trickery behind the scenes to
get correct unicode handling. I am not sure where the problem is. What
Django version are you using?


Sorry about forgotting version info. I tested with 1.3.1 and 1.4.1 and
both gave same behaviour.

And I know that there is quite a lot of trickery going on. I'll try to
figure out what causes that problem.

Hi,

I've been trying to save UTF-8 characters to oracle database without

I've verified that database is indeed UTF-8 capable.

I can insert UTF-8 characters directly using cx_Oracle.

But when I use ORM it will trash characters.

Model I use:

class MyTest(models.Model):
  txt = CharField(max_length=128)

s = u'0 \u0442\u0435\u0441\u0442 test'

i = MyTest()
i.txt = s
i.save()

i2 = MyTest.objects.get(id=i.id)
print i2.txt

u'0 \xbf\xbf\xbf\xbf test'

So what happens here? It looks like Django trashes my unicode string at
some (unknown point).

Additional note:

If I use cursor() from Django connection object strings get broken also.
So it must be django Oracle backend doing something evil for me.

Admin and ForeignKey

[Kristofer]

Hello, 

I have three models, defined like the following (code below simplified): 

class Shirt(Model): 
sku = CharField() 
description = CharField() 

class Color(Model) 
name = CharField() 
shirt = ForeignKey(Shirt) 
price = Decimal() 

class Order(Model) 
shirt = ForeignKey(Shirt) 
color = ForeignKey(Color) 

The admin page for shirt shows Color options inline, so that the name and price 
can be typed in. 

My views for the order form from customers are set so that only the appropriate 
colors are displayed for the shirt selected. 

However, in the Admin Order page, the Color field shows all of the colors for 
all shirts. How can I restrict the Color field to only show colors where the 
Color.Shirt foreignkey matches the Order.Shirt foreignkey?

Re: Can't sync DB

[Nick Sandford]

Since you have already created the table using syncdb, you need to instruct
South to fake the initial migration. Try the command ./manage.py migrate
auth --fake and see if that works. You only need to run this once and then
all future migrations don't need the --fake flag.

Cheers,
Nick

 Why did assigning a new DNS name for this IP address cause this CSRF

Yes, I checked my cookies and there is a csrftoken:

I didn't change the SESSION_COOKIE_DOMAIN value. There is no such setting

Re: HTML Source on Browser Rendering

[Ryoichiro Kamiya]

Thanks all for seeing this thread.

With further experiment, the result shows the HTML source with  tag 
even after emptying the contents of the Django template file. When I tested 
it in various browsers, the browser automatically added basic HTML 
structure with  tag on top of my contents. I compared the line endings 
and encoding with another page that working correctly, but couldn't find 
any difference.

I'll mark this as closed as it seemed not an issue resulting from Django.
Everyone, thanks for replying to my question. Have a nice day!

Regards,
Ryo

Yes, it should work if you reference the template *without* the app_name 
for instance 

{% extends "base.html" %}
{% include "footer.html" %}

or in python with «render(request, "base.html", ctx)» but you never render 
the base html or footer directly so this is dummy example

it only works if you reference the app_name when you call the template for 
instance «render(request, "app_name/index.html", ctx)» same for include and 
extends.

It's a convention to avoid clash between templates names, it a way to 
namespace templates, otherwise you would need to namespace the names of the 
templates like: «app_name_index.html» which is not nice...

CSRF Verification error appeared after I changed DNS

[Saqib Ali]

Hi.

I have been using Django successfully for a few days now. I was running my 
django application on an Amazon Web Service machine. 
I was assigned some arbitrary DNS name that looked like 
this: http://ec2-XXX.XXX.XXX.XXX.compute-1.amazonaws.com.
My Django app was working find with my model and several views with 
templates.

Last night, I went out and bought a real DNS name from register.com and 
have that DNS name now pointing to my django application.
Since I made that change however, when I submit my django form, I get the 
following CSRF error:


Forbidden (403)

CSRF verification failed. Request aborted.



I tried clearing the cookies in my browser, but that didn't help. I even 
tried it from other machines that I had never tried before. But still the 
same problem.

Why did assigning a new DNS name for this IP address cause this CSRF error? 
And how do I get rid of it?

Announcment - django-databrowse

[Alir3z4]

Hi,

Since Django 1.4 released, `django.contrib.databrowse` get deprecated.
And it's removed from 1.5.
Actually I hope django.contrib.* completely get wiped off django, I guess 
django development
will be faster and cleaner without those app.

I've extracted and adopted it.
Now it's available as stand-alone package pypi.

pypi:
http://pypi.python.org/pypi/django-databrowse

source/git repo:
https://github.com/Alir3z4/django-databrowse

Alireza Savand

I don't understand this part, are you programming in the browser ? or is it 
just about the design phase of each «Articles/bundle», work prior or in 
parallel of programming the site ?

I'm not sure but what you describe looks like a (e)magazine with several 
issues (you call them Articles/bundle) where each issue has it's own 
layout/design - and probably navigation but it seems also there is a global 
menu - a cross issues menu - present on all issues.

I assume by «synchronization» you mean «putting the new "Articles" in

Can you describe this navigation widget ? Is it available over all 
apps/Articles/issues ?

Do the Articles gets modified after the first synchronization ? Do you have 
somekind of administration to edit them ?

In the other mail you say «But I still find myself creating bare apps with 
some crazy model defined that only has 1 table row.», could you describe 
one of this table/row and generalize to the other similar tables ?

Re: ORM, Oracle and UTF-8 encoding problem.

[akaariai]

I created the following test case into django's test suite modeltests/
basic/tests.py:
def test_unicode(self):
# Note: from __future__ import unicode_literals is in
effect...
a = Article.objects.create(headline='0
\u0442\u0435\u0441\u0442 test', pub_date=datetime.n  ow())
self.assertEqual(Article.objects.get(pk=a.pk).headline, '0
\u0442\u0435\u0441\u0442 test'   )

This does pass on Oracle when using Django's master branch, both with
Python 2.7 and 3.3.

Django's backend is doing all sorts of trickery behind the scenes to
get correct unicode handling. I am not sure where the problem is. What
Django version are you using?

Re: sort cache

[psychok7]

hi there. redis does seem like a better solution than the cache.

i need redis (or the cache) because of performance reasons. i know they are 
faster for the insert and retrieve that i need in a FIFO order. Found this 
http://rediscookbook.org/implement_a_fifo_queue.html and it seems it will 
do the trick

thanks for your time

Re: Project Structure - Lots of scattered custom views

[Sanjay Bhangar]

hey all,

This seems to be an itch I've had to scratch myself in the past - let
me see if I understand the situation vaguely correctly:

You have a site that uses Django / database features for some things,
but then you also have a lot of content that's being designed in some
design tool and needs to be manually crafted into precise (sometimes
hackish) html and uploaded, and you almost want to just work with
plain html files on a file-system so you can use the tools you're used
to - Komodo / vim, version control, etc. This content is in the form
of "article bundles" which need to have some sequencing between pages.

The 'new app for every article' definitely sounds like a clusterf
it maybe an interesting experiment, but it just *feels* wrong at so
many levels .. you do want some way to generalize this into a single
app .. but my guess is you also are unable to wrap things into common
templates and editing the html in the database / django admin is just
too messy .. even if you let individual "articles" or "article
bundles" have their own custom css that's specified some-how in the
db, and their own custom html that you some-how populate from html
files you upload. It may work, and it is perhaps the correct way to do
this. I just know the situation where you're fighting with some silly
html generated by a design tool and actually want simple html files
and css resources, and the database "structure" can feel like its
getting in the way ..

So, here is my radical (?) suggestion :) -

Have a simple model like this:
class Item(models.Model):
  title = models.CharField(..)
  slug = models.SlugField(..)
  ... any extra metadata fields you need for the "article bundles"

Then, for each item "slug" name, you create a new folder on the
file-system in some path you define in settings.py or so like
CUSTOM_HTML_PATH or anything - so, say you have a series of articles
on "Why not to do webdesign in Indesign" with a slug like
"why-not-indesign", you create a folder inside CUSTOM_HTML_PATH with
the name "why-not-indesign". Then create the various articles in that
"bundle" like 1.html, 2.html, 3.html, etc. and include all the css /
js files that specific bundle needs inside a static folder in that
directory.

Then you just need a view which takes , looks for the
appropriate folder on the file-system, and renders 1.html inside
whatever master template you may have. The view can also check for all
the .html files in the directory to handle next / previous.
You would probably need to do a bit of magic with STATICFILE_DIRS or
so to make sure each of the static file folders inside the directories
are collected by collectstatic so you can still serve the static files
through the web server and not through django.

Of course, I don't know the details of your work-flow so I maybe
missing something, but I do in general find the idea of storing some
things just on the file-system quite interesting, and the code to
manage it is generally pretty straightforward.

Of course, this may also be a terrible idea, but I'd also love to hear why .. :)

Cheers,
Sanjay

Yes and no.

Django cache backend alone can't do this sort of things, the only methods 
that are 
definedare:

- get
- get_many
- set
- set_many
- incr
- decr
- delete
- delete_many

With those, you can do what you want, you have to set up a «schema» with 
cache keys that will allow you to do what you want.

Similarly you can also do this sort of things using 
redis, 
which is also pretty fast since it's also a in memory key/value store, 
using higher level methods on higher level data structures like lists, 
sets, sorteds sets, hashes. You might as well fallback on creating your own 
data structures relying on existing datastructures usings 
scripts
.

The usecase you are discribing is not clear, why not just do the sorting 
with mysql, store in the cache with an expiration key the results, ids or 
rendered templates ?

Re: Can't set static file directory.

[jianhui chen]

Hi,
   I am not to interrupt your question, actually I have the same problems
as you. It seems that Django comers suffer this problem so much.
   I use Manager Static File as a guide, but still has problem.
   1, Put your static files somewhere that staticfiles will find them
  I set following in the setting.py
  STATIC_URL = '/static/'

 # Additional locations of static files
STATICFILES_DIRS = (
   # Put strings here, like "/home/html/static" or
"C:/www/django/static".
   # Always use forward slashes, even on Windows.
   # Don't forget to use absolute paths, not relative paths.
   "E:/code/python/djangoBook/django-testapp-develop/static"  #this is
only used in my local test
  )
   2, Make sure that django.contrib.staticfiles is included in your
INSTALLED_APPS
.
  So I set that:
   INSTALLED_APPS = (
#'django.contrib.admin',
'django.contrib.contenttypes',
'django.contrib.auth',
'django.contrib.sessions',
'django.contrib.staticfiles',   #this
'djangotoolbox',
'autoload',
'dbindexer',
'shape_practice',

# djangoappengine should come last, so it can override a few manage.py
commands
'djangoappengine',

)
   TEMPLATE_CONTEXT_PROCESSORS = (
 'django.contrib.auth.context_processors.auth',
   'django.core.context_processors.request',
   'django.core.context_processors.media',
'django.core.context_processors.static',  #this
 )
  3, You’ll probably need to refer to these files in your templates.
   So I did this:

  

  And, so someone pointed out that : using
RequestContext,
so I dit that
  def introduction(request):
t = loader.get_template('introduction.html')
c = RequestContext(request, {})   #this
return HttpResponse(t.render(c))

  The problem is that when I comment out
"E:/code/python/djangoBook/django-testapp-develop/static" in the
STATICFILES_DIRS , it has an error :

"NetworkError: 500  -
http://127.0.0.1:8000/static/images/gauge_example.jpg";. When I didn't
commented out, it works. So I think STATICFILES_DIRS and STATIC_URL
actually works in

my app, the problem is that how to set it to the correct path. In my
case, I want to STATIC_URL can find my "static" folder which is in the
project home directory.

  I was puzzled by this problem many days, right now I have no way but
to use local folder
"E:/code/python/djangoBook/django-testapp-develop/static" to code and
test in my PC.

  Thanks.

Jianhui

ORM, Oracle and UTF-8 encoding problem.

[Jani Tiainen]

Hi,

I've been trying to save UTF-8 characters to oracle database without 
success.


I've verified that database is indeed UTF-8 capable.

I can insert UTF-8 characters directly using cx_Oracle.

But when I use ORM it will trash characters.

Model I use:

class MyTest(models.Model):
txt = CharField(max_length=128)


s = u'0 \u0442\u0435\u0441\u0442 test'

i = MyTest()
i.txt = s
i.save()

i2 = MyTest.objects.get(id=i.id)
print i2.txt

u'0 \xbf\xbf\xbf\xbf test'


So what happens here? It looks like Django trashes my unicode string at 
some (unknown point).


Additional note:

If I use cursor() from Django connection object strings get broken also. 
So it must be django Oracle backend doing something evil for me.

Re: image list

If these are images already available on your server, which the user simply
selects,
using JavaScript that you have written, then have only to send the
rearranged list
back to the server.  This can be done with a POST, either using AJAX, or a
more
traditional FORM tag POST that also reloads the page.  The latter is the
simpler
approach to make functional, at the cost of letting the user see the page
reload, but
once it is working, it serves as a head start on the AJAX approach.

In either case your first task is to decide how the image selection
information is to
be stored in the server's database.  A flexible approach is to have a
"Picture" model
which mostly contains an ImageField, allowing for image upload withing
Django,
among other things.  Then the model of the pages containing the images is
related
to the Picture model via a ManyToMany relation, though one "through" an
intermediate
model which has an order integer field, or perhaps row and column integer
fields.
This may be a more complex structure than you require, but should suffice
for most
needs.

Next, the JavaScript that re-orders/selects/deselects the images must also
update a
field or fields in a form tag so that when the form's submit button is
clicked, the new
arrangement is transmitted to the server.  (You could, alternatively, catch
the submit
and update the form field at that time.)  Because the number of images, and,
presumably, the number of rows, is variable, I suggest a single textarea
field in which
you store JSON for the arrangement (e.g.; arrays of arrays of integers,
where the
integers are the database IDs of the Picture models).  Again, other
arrangements are
possible.  One might be to send information about what changed, rather than
the
entire arrangement of images, but this is more brittle.

Finally, the view which receives the POST is responsible for decoding the
JSON
and updating the intermediate model instances to correspond to the new
arrangement.  One approach is to delete all the intermediate model instances
(relations) and recreate new ones from the submitted data, and I suggest
that you
start with this.  It may (or may not) save database overhead to figure out
what
changed and just update or replace relations that have changed.

The AJAX approach will also be doing a POST, using, for example, jQuery's
post
method, and the view will be nearly the same (it need not return the new
HTML
version of the page in this case).  The AJAX POSTs would happen if response
to
a user change to the page, rather than requiring a submit button be
pressed, and
are much more likely to benefit from transmitting only what has changed,
rather
than the entire arrangement, but this can be left as an eventual
optimization.

show an image in django

[jianhui chen]

Hi all,
I want to show an image in project in which the folder DIR looks like this:
images/a.jpg
templates/introduction.html

In introduction.html I use


It can show image correctly when I open the "introduction.html" directly
using firefox, but it shows ""GET /images/gauge_example.jpg HTTP/1.1" 404 "
when I open it in http://127.0.0.1:8000/introduction/, and there is no
image in the webpage.

I used the last method in
http://stackoverflow.com/questions/2148738/cannot-get-images-to-display-in-simple-django-site.
But it doesn't work.

Could anyone give me some suggestions?

Re: Can't set static file directory.

[Jonathan]

Assuming that you have settings.STATIC_ROOT configured, you can use the
following snippet to handle URL routing for static files with the dev
server:

# urls.py
if settings.DEBUG:
urlpatterns += patterns('',
(r'^static/(?P.*)$', 'django.views.static.serve', {
'document_root': settings.STATIC_ROOT,
}),
)

Feel free to add a similar pattern for media files as well.

Hope this helps,
Jonathan

Re: Syncdb error with new 1.5rc1

[Thiago Carvalho D' Ávila]

Basically, I am using Person class as my AUTH_USER_MODEL. I realized it was
missing 'username' in REQUIRED_FIELDS.

from django.contrib.auth.models import UserManager, AbstractBaseUser
...

class Person(AbstractBaseUser):
objects = UserManager()
username = models.CharField(_('username'), max_length=30, unique=True,
help_text=_('Required. 30 characters or fewer. Letters, numbers and
'
'@/./+/-/_ characters'))
email = models.EmailField(_('e-mail address'), unique=True, blank=True,
null=True)
...
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['username']

But it continues to give me error to syncdb:
You just installed Django's auth system, which means you don't have any
superusers defined.
Would you like to create one now? (yes/no): yes
E-mail address: e...@il.xx
Username: test
Password:
Password (again):
TypeError: 'is_active' is an invalid keyword argument for this function

There is no is_active reference in my model.

Hello.

I try a lot of things and can't understand, why not working
STATIC_ROOT and MEDIA_ROOT in settings.py.

I want, that all my media and static folders is in different place
that python files, so I set media, static and templates to different
place. Templates TEMPLATE_DIRS works well, bet MEDIA_ROOT
and STATIC_ROOT not.

I try setup like this:

/home/domain/www/my_proj/ there is project folder and all apps, and
there I place my htdocs folder, in which is static, templates and
media folders.

When i set in STATIC_ROOT = '/home/domain/www/my_proj/htdocs/static'

In apache error log i got:

File does not exist: /home/domain/www/my_proj/my_proj/static

I don't get, why django don't want to take new setting...

I use django 1.4.


I think you need to set up Apache to serve the static and media files. 
Here is how mine works ...


 # lock the public out
 
  AllowOverride None
  Order deny,allow
  Deny from all
 

 # serve uploaded media from here
 
  AllowOverride None
  Order deny,allow
  Allow from all
 

 # serve static stuff from here
 
  AllowOverride None
  Order deny,allow
  Allow from all
 

 
  Alias /media/ /var/www/media/my_proj/
  Alias /static/ /var/www/static/my_proj/
  Alias /tiny_mce/ /var/www/static/my_proj/js/tiny_mce/
  Alias /jquery/ /var/www/static/my_proj/js/jquery/
 

Then in your template you can use {{ STATIC_URL }}/whatever

Hope this helps

Mike

Re: Can't set static file directory.

[joy]

I have the same problem, the tutorial speaks about a list of things to do:

   - Push your code up to the deployment server.
   - On the server, run 
collectstaticto
 copy all the static files into 
   
STATIC_ROOT
   .
   - Point your web server at 
STATIC_ROOT
   .

I have arrived at the second point. But the static files are not served, i 
have set up the STATIC ROOT and the STATIC_URL, but what should i add to 
the template src tag to find the pages? The tutorial speaks about the 
template context processor, but it doesn't exist in my setting.py file.

TEMPLATE_CONTEXT_PROCESSORS = (
'django.core.context_processors.debug',
'django.core.context_processors.i18n',
'django.core.context_processors.media',
'django.core.context_processors.static',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',)

i cannot make my css and javascript work, please, can you explain me what is

Re: OperationalError: (2003, "Can't connect to MySQL server on 'localhost' (10061)")

[Diederik van der Boor]

The hostname "localhost" has a special meaning for MySQL, at least on Linux it 
has.
When you ask the mysql driver to connect to localhost, it will use the socket.
To avoid this issue, better use 127.0.0.1.

Also check whether the MySQL server is running on that port (netstat -a ?),
whether the service is up (see services panel),
and whether your Windows Firewall allows connections to it.

Greetings,
Diederik
