Re: Django for non web clients

[Rahul Gaur]

Hi,
What about change-tastypie or django-restframework or something similar ?
As a part of my GSoC project [1] , I am implementing a project sharing web
site with social features.
I need RESTful APIs so that the functionality of the site could be
integrated into SugarLabs [2].

I am planing to use Django with one of the above rest frameworks to serve
RESTful APIs  and a web client in backbone.js which will consume the APIs
as well.

data transfer between databases

[Mike Dewhirst]

This is probably a Postgres question but someone might be able to offer 
advice on how to transfer data :)


New "reference" or read-only data gets input during development and I 
want to transfer it to the production database from time to time.


I think my choices are:

1. Re-enter it manually - only if all else fails.

2. Use Django's multi-database feature and write a utility to transfer 
data which doesn't already exist. Except the databases are on different 
machines in different data centres.


3. Exploit some pre-existing tool written for precisely this problem.

Any suggestions?

There are currently three reference tables involved and two have m2m 
relationships between themselves. The other is stand-alone.


Customer data is fine in the production database and won't be touched. 
There are no relationships with the reference tables.


Thanks

Mike

Re: Ajax

[Christian Schmitt]

Every Framework supports Ajax. But as i already mentioned and as already 
talked about in the django-developers, the support of serialization and 
other things is really really crappy and needs to be fixed.
Especially SPA sites needs some love. I mean in the core Django is cool, 
and since the new cbv's i really love django and the ajax support is better 
now, but some things are still messy.

Re: Get Form from string?

[MacVictor]

I try in view get the form by name.
Example:
this is my url: 

/some-url/MyForm/

url(r'^/some-url/(?P[a-zA-Z0-9]+)/', 'my_view', name='my-wiev'),


and my view:

def my_view(request, form_name):
form = how_get_form_name(form_name)
response = {}
response['my_form'] = form
return render_to_response('request/window.html', response)


I have create uniwersal view, get my form and send to template. Why form? 
Because my model has more Forms and I want to select which forms.

Sorry but I forgot show my form:

This is my Form:

class MyForm(ModelForm):
class Meta:
form = 'my_form'
model = MyModel
exclude = ('country', 'region')

My all form in subclass Meta contains variable 'form'. This is name of my 
form. The definition get_form search in all included form one string name, 
and return this Form.

Example:
url:

url(r'^/some-url/(?P[a-zA-Z0-9]+)/', 'my_view', name='my-wiev'),

and view:

def my_view(request, form_name):
form = get_form(my_form)
response = {}
response['my_form'] = form

Re: Django for non web clients

Thanks Rahul,

I thought about that. 

I do not need Django's ORM as I do not use relational db and I do not need 
Django's Templates as I use rest api. So I am not sure what value does 
django add in my case?

Lowest level approach will be just using pgdump for the spesific table or whole

Re: Django for non web clients

[Rahul Gaur]

Both the above mentioned frameworks offer support for non orm data
resources.
See tastypie's official docs on how to use it with riakdb [1] .

And I have also used django rest framework to relay RESTful APIs for a
django app which uses restful apis from a locally running REST server.

So the data source here wasn't rdbms or non-rel db but json feed from local
web server.
Since this server had a django based web  interface which consumed these
APIs , and we couldn't expose this directly to web as it expose lots of
level and raw data.

Whereas the django based web app offered limited functionality that we
would like to offer clients with  api as well.
Rolling out authenticated public facing restful APIs with django made more
sense .

Using these frameworks I am under the impression  that I could develop
product faster as compared to rolling out my own APIs  and authorization
and authentication is less complex as already there are very good existing
django apps that ease the job (dry) :-)

Just my thoughts :-)

Re: send query by using a textbox of html to python(django)

[Daniel Drummond]

Try following the tutorial here.  By the end of it yous hould be able to 
answer this yourself.  It doesn't take long to do, and you'll understand 
enough about Django to be able to extend your solution.

This is really a question about regular expressions, not about Django. 
Whether you implement simple or complex search in Django, whether you use 
Django or some other platform, this is going to come down to using a fairly 
complex regular expression. So I would search for "regex ignore vowels" and 
similar. I would also expect performing a search like that to be extremely 
expensive, computationally, since it will need to tear apart every single 
word in the pool. That, in turn, means you'll want to use a search system 
with very robust indexes. In fact, you might do best with a system that 
pre-indexes all of your content without vowels.

but I want it to be a very good search.Please help me.

Re: django search query

[Amirouche Boubekki]

You can do this by creating an extra field in the model with the name
without vowels in it and doing a simple filter on it ? Is that what you
need ?

Re: data transfer between databases

Thanks for your suggestions. Dumping data isn't the entire problem - 
which is this:


There will be an *ongoing* need to add new data from tables in one 
database to the same-named tables in another database on a remote 
machine. Two of the tables are in a m2m relationship.

New "reference" or read-only data gets input during development and I

I think my choices are:

1. Re-enter it manually - only if all else fails.

2. Use Django's multi-database feature and write a utility to transfer
data which doesn't already exist. Except the databases are on different
machines in different data centres.

3. Exploit some pre-existing tool written for precisely this problem.

Any suggestions?

There are currently three reference tables involved and two have m2m

Customer data is fine in the production database and won't be touched.
There are no relationships with the reference tables.

FWIW - I have a site for which I need to do that, I use MySQL so I just dump

There is some scripting around it to keep track of IDs so I dump deltas only, 
works just fine.

You should be able to use the same technique on Windows 7.

1. Download the Django 1.6 zip file and unzip it into a temporary 
directory.


2. Get a command prompt and cd into the directory containing setup.py 
which is under the temporary directory


3. Execute the command "python setup.py install"

Should work.

I use Postgres but I'm sure that doesn't matter much. Would you be able 
to share your scripts? Off-list if you prefer. When I get it working 
I'll try and refine things so it becomes an easily repeatable process

Re: Change template block via AJAX

[Andre Engelbrecht]

What I normally do is to have a include template that contains only the 
content I would like to render.
I example:

{% block page_content %}

{% include 'xhr_page_content.html' %}

{% endblock %}

Using this approach you have isolated the content. Loading the page without 
ajax will just load the page as normal, and will include everything.
Now to make the ajax load all you need is to modify your view to check for 
request.is_ajax(), and if true, you change your view to render 
"xhr_page_content.html", instead of the full template.

That was the summary, hope it's clear enough.

Django 1.6 doesn't install via pip

Hola,

I read the release notes, and tried to install 1.6. I encountered this error:

$ pip install Django==1.6b1
Downloading/unpacking Django==1.6b1
  Could not find a version that satisfies the requirement
Django==1.6b1 (from versions: 1.2.6, 1.3.6, 1.2.7, 1.2.3, 1.2.4,

1.4)
No distributions matching the version for Django==1.6b1


I presume that the 1.6 alpha/beta hasn't been pushed to pypi yet?

cheers

I have a search function which is already working in views.py but I

And what is django-haystack application? Can I use it in my project

dajaxice file cannot be found

[no body]

I am usering django_dajax 0.9.2 and django_dajaxice 0.5.5 for my current
project. This is how I configure it


#settings.py

*MAIN_DIR = os.path.dirname(__file__)
PROJECT_DIR = MAIN_DIR.rsplit(os.sep, 1)[0]

# Example: "/home/media/media.lawrence.com/static/"
STATIC_ROOT = os.path.join(PROJECT_DIR, 'static')

# URL prefix for static files.
# Example: "http://media.lawrence.com/static/";
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.
os.path.join(MAIN_DIR, 'static'),
)

# List of finder classes that know how to find static files in
# various locations.
STATICFILES_FINDERS = (
'django.contrib.staticfiles.finders.FileSystemFinder',
'django.contrib.staticfiles.finders.AppDirectoriesFinder',
'dajaxice.finders.DajaxiceFinder',
)*

and my urls.py
*
from dajaxice.core import dajaxice_autodiscover, dajaxice_config
dajaxice_autodiscover()

if settings.DEBUG:
urlpatterns = patterns('',
(r'^media/(?P.*)$', 'django.views.static.serve',
{'document_root': settings.MEDIA_ROOT}),
)

urlpatterns += patterns('',
url(dajaxice_config.dajaxice_url, include('dajaxice.urls')),
...*


With this settings, I am enable to use these libs in my local machine.
However, when deploying to the client machine, the file dajaxice.core.js
cannot be found (see it on firebug). When use *python manage.py collecstatic
*, I see that that file is saved into the folder temp (*Copying
'/tmp/tmpsiiuMx'*). The rendered link is correct

**

and there is indeed that file under the /static/dajaxice folder, but still
the browser complains about cannot find that file. Do you have any idea
about this ?
