Re: Can I POST edit form to detail view, and redirect back if invalid?

[Hemebond]

Oh, and also AJAX requests could then do everything on the object URI
(since they won't need the forms). Maybe it could be done with
temporary objects in the database. Use a randomised value in the
redirect URL to re-fetch what the user typed in and the errors
associated, then discard the entry.

Template file not recognized for some strange reason

[Mika]

I'm working through one of the template examples in the django book
and the template file I created isn't being recognized for some reason
even though it's in the folder. The error report is at the bottom of
the page. The TEMP_DIRS variable is set to the correct file path in my
settings file:  TEMPLATE_DIRS = ("/Users/Documents/Music\ App/redlab/
templates",)
The view function is in order too:

from django.template.loader import get_template
from django.template import Context
from django.http import HttpResponse
import datetime
def current_datetime(request):
now = datetime.datetime.now()
t = get_template('current_datetime.html')
html = t.render(Context({'current_date':now}))
return HttpResponse(html)

The url file is also in order:

from django.conf.urls.defaults import*
from redlab.views import current_datetime
urlpatterns = patterns('', (r'^time/$', current_datetime))


And there is a current_datetime.html file in the templates directory
with the following code in it:
It is now {{ current_date }}.


But the file isn't being recognized for some reason. Please advise.
thnx.

Re: Can I POST edit form to detail view, and redirect back if invalid?

[Hemebond]

I can definitely write my code the normal way. I just wanted to see if
it was possible; perhaps some way I hadn't thought of. I just liked
the idea of all CRUD operations being done on the object URI.

Take a look at ganeti web manager, it's a Django site for managing
ganeti virtualization clusters. It doesn't do any of the python specific
stuff you're talking about but does do the
creation/deletion/boot/restart/remote console for virtual machines.

Could be a good starting point for you.

Web App Systems Management Tool for Ubuntu Platform

[Eduardo Bergavera]

Hi Everyone!

I would like to ask some guidance regarding anyone who may be
interested in developing web-based python app for systems management
in Ubuntu. The web-app acts as centralized interface to manage cloud
based or physical Ubuntu servers in one location. I'd like it to be
developed using web2py framework. The system has features found in
Ubuntu's proprietary systems management tool like Landscape
--(http://www.canonical.com/enterprise-services/ubuntu-advantage/
landscape/systems-management)
a remote management tool for Ubuntu servers and desktops. The project
combines some essential features of Webmin (webmin.com) and Landscape.

System Requirements:

* Django based web app
* manages Ubuntu desktop or servers thru a single interface
* require registration of clients (desktop or servers) to be managed
by the system
* install, remove, upgrade packages, update history
* Manage users (create, remove, change password)
* View system info (cpu, ram, io)
* email notification such as status of services, package updates
* support common basic configurations
* ability to explore filesystem
* reboot, shutdown remote servers
* log viewer (/var/log)


Thank you for your help and guidance.

I give it a second thought and I think that you were absolutely right
Danniel. In (1) the post_save is called with a new object that no
longer exists when post_save is called and with (2) is called with
self.instance that still exists after post_save. Thanks and sorry for
not catching it at the first time.

thanks again :)

Problems with {% url %} in templates

I'm very confused… this has worked fine in the past. Django 1.3.1

In myproject/urls.py:

urlpatterns = patterns('',
(r'^d/events/(.*)$', include('myproject.events.urls')),
[…]

in myproject/events/urls.py :

urlpatterns = patterns('myproject.events.views',
   url(r'^add/$', 'add_view', name="event-add"),
[…]


Both:

{% url events.views.add_view %}

and

{% url event-add %}

Throw:

Caught NoReverseMatch while rendering: Reverse for 'event-add' with arguments 
'()' and keyword arguments '{}' not found.

(Or "Reverse for 'myproject.events.views', as appropriate.)

This must be something absurd… anyone see what I'm missing? Think I've been up 
too long.

Re: Auth app in separate database

[Chris]

I setup my router following the docs.

Here's what my router.py looks like:

AUTH_APPS = ('auth',)

class MyRouter(object):
def db_for_read(self, model, **hints):
if model._meta.app_label in AUTH_APPS:
return 'auth'
return None

def db_for_read(self, model, **hints):
if model._meta.app_label in AUTH_APPS:
return 'auth'
return None

def allow_syncdb(self, db, model):
"Make sure the Auth apps only appears on the 'auth' db"
if db == 'auth':
return model._meta.app_label in AUTH_APPS
elif model._meta.app_label in AUTH_APPS:
return False
return None

Removing auth from the default database seems to cause issues with 
contenttypes and create errors on syncdb. auth and contenttypes seem to be 
dependent on each other.

It won't. The {% with %} tag cannot arbitrarily call custom tags.

Best approach to execute tasks inside django admin views

[Marc Aymerich]

Hi guys,
I have an application that execute some tasks after an object is
modifyed through django admin interface. In order to do that I'm
subscribed to django.contrib.admin.models.EntryLog post_save signal
and for each signal I execute a celery task.

As you migh know django admin views are running under
commit_on_success transaction so executing tasks within can lead to
some issues, good explained on the celery documentation:
http://ask.github.com/celery/userguide/tasks.html#database-transactions

So my question is, how do I should deal with this transactions?
it is possible to manually commit a commit_on_success transaction
before calling the task?
if not, what would you do? monkeypatch django admin views to use
commit_manually?
subclass all your project modelAdmin classes? (I'm using a lot of
reusable applications)

thank you guys!

Re: comparing custom template tag within if tag

[Josh Cartmell]

I think something like this would work:
{% with price_for_pax service pax '' as pfp %}
{% if service.price == pfp %}
  do something
{% endif %}
{% endwith %}

Alternatively if price_for_pax is only used for comparing to
service.price you could have it return true or false based on whether
whatever equaled service.price, and then use it more directly.

Regards,
Josh

Re: Auth app in separate database

[Josh Cartmell]

Couldn't he also just add the router before syncdb and then they would
be created in the correct database?

Chris take a look at this documentation if you haven't already, it
explains routers which tell Django which database to use for a
particular query:

Re: Can I POST edit form to detail view, and redirect back if invalid?

[Mjumbe Poe]

You're correct: HTTP does not allow you to, say, send POST data along
in a 30X (redirect) response [1].  You can redisplay the form at your
object's URL, but in order to actually do an HTTP redirect back to the
form URL, you'd have to pass the form data along in the URL query
string or store it on the session or something.  The easiest thing to
do in most cases is to POST to the /edit/ URL and redirect to the
detail page (or somewhere else) if valid.  This is what the [Create|
Update]View classes do.  Could you provide a little more context on
why this is infeasible in your code?  Maybe an snippet?

I think this is more accurate. You should try to sit within the
conventions used with HTTP in order to have a good experience.

You should present your form at a particular URI. If the form data is
valid, save the data, and redirect to a palce to view the data.

Eg,

» GET /widgets/create
« Django renders object creation form
* User fills in form
» POST /widgets/create
* Form is not valid
« Django renders bound object creation form, with errors highlighted
* User fills in form correctly
» POST /widgets/create
* Django creates object
« Django redirects user to /widgets/by-id/1
» GET /widgets/by-id/1
« Django renders object edit form

etc.

If you don't want to do it the standard way, there must be some
compelling reason. Care to share?

Cheers

Tom

In Django, urlconf doesn't care about whether you are posting or
getting or deleting.  It just dispatches to your view.  In your view
you check request.method and code accordingly.

I'm just learning Django myself, so others might tear this code apart
but take a look.  Whether you come to this url with POST data or not
alters the logic.  If POST then validate, and save.  If not post, then
fill in the form and display.  If no data to fill in, then display a
blank form.  The print statements show up on stdout of the terminal
that you start your dev server.

def edit_hotel_profile(request, hotel_id):
hotel_id = int(hotel_id)
print 'Editing hotel profile with hotel_id: %d' % hotel_id
if request.method == 'POST':
print "in edit_hotel_profile with POST data for hotel_id: %d" % hotel_id
#hotel_profile = HotelsHotelProfiles.objects.get(pk=hotel_id)
hotel_profile = HotelProfiles.objects.get(pk=hotel_id)
f = HotelProfileForm(request.POST, instance=hotel_profile)
#hotel_entry = f.save()
print f.errors
#e = f.errors
if f.is_valid():
hotel_entry = f.save()
print hotel_id, "saved to db"
else:
return render_to_response('hotels/hotel_form.html', {'f' :
f,}, context_instance=RequestContext(request))

try:
print "in edit_hotel_profile with no POST data for hotel_id:
%d" % hotel_id
#hotel_profile = HotelsHotelProfiles.objects.get(pk=hotel_id)
hotel_profile = HotelProfiles.objects.get(pk=hotel_id)
f = HotelProfileForm(instance=hotel_profile)
#f.save()
except:
print e
f = HotelProfileForm()
print 'rendering blank form'
return render_to_response('hotels/hotel_form.html', {'f' : f,},
context_instance=RequestContext(request))

Yes, although when you change a model (adding another field), Django
will not automatically change the database structure for you. So you
would need to do that manually.

Django is not really designed to dynamically add/remove fields, or
indeed models, but yes, it can be done. However, wanting to do
something like that it is normally a sign that you have a bad design.

Re: is doing text manipulations in django's template faster than doing same in views

[Andre Terra]

If you're doing a lot of operations with your data, there's a chance it
should be moved to the view. The template should usually be restricted to
defining *how* data gets displayed, whereas the view defines *what* your
data is.

You need to look at form handling in django.  Here is a good starting
point: http://www.djangobook.com/en/2.0/chapter07/

Then look at model forms.

Re: Can I POST edit form to detail view, and redirect back if invalid?

[Hemebond]

What can I pass back to the edit form view that already contains the
values and errors and how? Posting to the edit form view would work
but that would re-process the form.

Can I POST edit form to detail view, and redirect back if invalid?

[Hemebond]

I want to use the URL of an object (a detail view) as the destination
for CRUD operations. I want it to be able to accept GET, POST and
DELETE requests.

As part of this, I want the edit form (retrieved by appending /edit/
to the object URL) to submit to the object URL. If the form is
invalid, I then need to redirect back to the edit form, and display
the errors.

Is this possible? Is there a way to redirect back to the edit form
with the new values and the errors that occurred during processing?

Hi Daniel,
thanks for your answer!
mmm, but deleting like
MyModel.objects.get(pk=self.instance.pk).delete() self.instance will
continue exist too, isn't it?

How Admin can be able to configure Model fields

[Deepak RK]

Admin can add another field in any model (lets say UserProfile ) and
it should start appearing in registration form.

self.instance.delete() will delete the item from the database, but the 
instance itself will still exist in memory. As long as you don't save it, 
it will disappear when it goes out of scope, or you can explicitly call 
del() on it.

I'm not sure this is the best place to ask how to use tweepy*. I know
about django, not tweepy, so I can't tell you if you are using the
tweepy API correctly.

You're returning inside a loop. This means that the first time status
is true, you will exit the loop. I'm not sure that is intentional.

'for status in status' is probably going to work, but why be so
confusing? Also, what is this 'status' variable? You are passing no
variables named status to the template - in fact, you're not passing
anything.

Cheers

Tom

* This is one of my pet peeves. Just because you are using django +
(random bit of software), it doesn't mean you well get good support
for (random bit of software) on the django mailing lists.
