Trivial view sometimes fails in Chrome

[Pigletto]

Simple view, shown below, sometimes fail in Chrome browser (request is shown 
as Pending or doesn't return any content):

def exposer(request):
return HttpResponse('Response from AJAX exposer')

That is called by AJAX, eg:
$.post('{% url exposer %}', {'bb':'aa'}, callback);

Suprisingly if I change my view to:

def exposer(request):
request.POST  # yes, just call it
return HttpResponse('Response from AJAX exposer')

it works properly. 

Also, If I don't send any data with my POST request it works:
$.post('{% url exposer %}', {}, callback);

Problem exists only in Chrome browser and in WSGI environment (I've checked 
with uWSGI and Cherokee, Django 1.3 and trunk).

Example application that exposes the problem:
https://bitbucket.org/pigletto/chrometest/src

Live version of this application at: 
http://chrometest.natcam.pl (clicking first button sometimes fails in 
Chrome).

Application might be installed with:
python bootstrap.py --distribute
bin/buildout
bin/django syncdb

Above will install uwsgi at bin/uwsgi, and uWSGI can be run with:

 bin/uwsgi -b 8192  -s 127.0.0.1:1088 -p 1 -z 15 -l 128 --wsgi-file 
bin/django.wsgi


Any ideas what happens? Why does use of request.POST change behaviour?

Add to database

[jose osuna perez]

 I have reviewed the document 
https://docs.djangoproject.com/en/dev/topics/db/queries/
but I can not insert the field users, the models.py table, I try as
follows, is this what was spinning in the other issue, not the
complete code, thanks:

for i in request.POST.getlist('usuarios'):
  usuario=User.objects.get(id=i)
 Proyectos.usuarios.add(usuario)

And my models.py file it's the next:

class Proyectos(models.Model):
titulo=models.CharField(max_length=100)
creacion=models.DateField(default=datetime.datetime.now)
estado=models.CharField(max_length=30)
objetivo=models.TextField(null=True)
conclusion=models.TextField(null=True)
porcentaje=models.IntegerField()
modificado=models.DateTimeField(default=datetime.datetime.now)

usuarios=models.ManyToManyField(User)
proyectos_rel=models.ManyToManyField("self")
documentos=models.ManyToManyField(Documentos)
class Meta:

noob struggling with inlineformset_factory

[trubliphone]

Hello,

I am new to Python and Django and struggling with the concept of 
inlineformset_factories.


I am trying to have a view that nests one form inside another.  Consider 
these models:


class PersonModel(models.Model):
name = models.CharField(max_length=255)
job = models.ForeignKey(JobModel)

class JobModel(models.Model):
description = models.CharField(max_length=255)

I want to display a set of nested forms, where the "job" field of 
"PersonModel" corresponds to a form based on "JobModel."  I am attaching 
an image of what I mean.


However, using the default behavior:

class PersonForm(forms.ModelForm):
class Meta:
model = PersonModel

I wind up with the "job" field corresponding to a combobox.

I thought that using an inlineformset_factory could solve my problem, 
but this code:


def index(request):
PersonFormSet = inlineformset_factory(JobModel,PersonModel)
return render_to_response('person/index.html, {'formset' : 
PersonFormSet, })


with this template:



{{ formset.as_table }}




doesn't work; It displays the "name" field but just ignores the "job" 
field.  And it I provide the keyword argument "extra" to the 
inlineformset_factory function, the view displays that many copies of 
the "name" field.  Clearly, I don't understand something.


Any ideas on what I'm doing wrong?  Should I not be using an inlineformset?

Many thanks for your help.

Re: Help with implementing dynamic views/models

[xenses]

I thank you for your help and apologize for my naivete, however I
still am not seeing that tag populate in the template. Here is my view
function in its entirety:

 def test(request, testn):
try:
testn = str(testn)
page = Page.objects.filter(name = "test%s" % testn)
return direct_to_template(request, template="test%s.html" %
testn, extra_context={page:page})
except ValueError:
raise Http404()

I am using {page:page} because anything else returns errors in debug
mode.
in my template I have :

{{ page.leaderboard }}

the page object looks like this:

class Page(models.Model):
name = models.CharField(max_length=25, verbose_name='Page Name')
leaderboard = models.TextField(max_length=500, null=True,
blank=True, verbo\
se_name='Leaderboard Tag')
rectangle = models.TextField(max_length=500, null=True,
blank=True, verbose\
_name='300x250 Tag')
rectangle2 = models.TextField(max_length=500, null=True,
blank=True, verbos\
e_name='Additional 300x250')

def __unicode__(self):
return self.name

I know that once I figure this out, I'm going to feel rather daft and
I appreciate all the help you've given me! Thanks so much!

Re: Iteration over queryset in a model

[eyscooby]

slowly getting there thanks to your help.
I am actually trying to accomplish this in the Admin interface, so I
am not sure how to use the template tag {{ ticket.days_old }} in that
situation.

the other part I left off yesterday under my model I then had..
(trying to get code formatting correct but keeps going to the left
margin on me when i post)

def days_old(self):
return self.objects.datecalc()
days_old.short_discription = 'Days Old'

more or less is that a correct way I would pull in a custom manager,
lets say if this one didn't have the iteration to it which seems be to
be my problem part now.

thanks

RE: Need advice on ForeignKey query problem.

[Sells, Fred]

Thanks Kevin, you got me on the right track.   I was able to implement the 
following solution:

records = models.Facility.objects.filter(...)
for x in records:
schedule = x.schedule_set.all()

But I could not find a way to do it all at once like

records = models.Facility.objects.filter(...).schedule_set.all()

If there is not a "clean" method to do this, I'm inclined to use the above 
solution since I have only ~100 records in the first query.  I don't want to 
"drop into SQL" unnecessarily.  On this query, I probably only need the 
.count() method on schedule_set() if that even makes a difference.

This line

(r'^zones/(?P[.\w]+)/$', zones)

just fine

what changes would I need to make to this line to also match domains

44.44.44.in-addr-arpa

11.11.11.in-addr-arpa

Try it with {'page': page} as your extra_context. The keys in a context

Sample Custom Decorator

[Kurtis]

Hey Guys,

Would anyone be willing to show me an example of a very simple and
dumb decorator for views? I've been trying to read the existing
decorators and play with a couple of snippets but I'm having a lot of
trouble with two aspects -- grabbing the User Instance and Redirecting
somewhere besides Login (without making it look like a hack).

Here's some ugly pseudo-code for what I'm trying to accomplish...

# Custom Decorator
def my_decorator(function = None)

# Grab Data
request = how_do_i_get_this?
user = request.user

# Perform Logic, Redirect or Continue Normally
if user.foo():
redirect to '/foo' URL
else
display requested view?


# Decorated TemplateView
url(r'^$', my_decorator(TemplateView.as_view(template_name =
'bar.html'))),

Thanks!

Re: Add to database

[Brett Epps]

I think you need to look up a specific Proyecto object before trying to
add users to it. So:

proyecto = Proyecto.objects.get(...)
for i in request.POST.getlist('usuarios'):
usuario = User.objects.get(id=i)
proyecto.usuarios.add(usuario)

Hope that helps,

Brett

Re: Trivial view sometimes fails in Chrome

[Kurtis]

Honestly I don't have any experience with Django and AJAX Yet. Just in
case you haven't checked it out yet -- I've read you've got to submit
the CSRF with your calls though. Not sure if that helps at all. Good
luck!

Hi,

You just need to add a "-" in your regex, like this:

Re: Help with implementing dynamic views/models

[Laura C.]

that at least gave me an output, but the output is: []

I have a potential to need 3 attributes from each object in each
template, so the mapping may not be what I need. If I pass in a
context object, I thought that I should have handles for
object.attribute ?  Or maybe I need to map the dict before passing it?

Min/Max value on FloatField

[Craig Blaszczyk]

Hi,

I'm wondering if there's a recommended solution for a FloatField which 
requires a minimum value? IMHO the best solution would be a ModelField 
implementation which provides this functionality. Can anybody recommend one, 
as I prefer not to implement it myself?

Cheers,
--Craig Blaszczyk

Thanks for the tip but I've switched CSRF off. 

I've just noticed that switching off 'keep-alive' at Cherokee solves this 
problem, so issue might be related to Cherokee... though I'm not sure - why 
it works after placing call to request.POST in my view?

Re: Help with implementing dynamic views/models

[Brett Epps]

The reason for that output is that page is a list, not a single object.
If you want a specific page, use Page.objects.get instead of
Page.objects.filter.

sounds like Cherokee needs that the app reads the content.  sounds
like a bug, or at least non-conforming.  don't remember what the RFC
says, but i'd take it to the Cherokee devs.

Still getting IntegrityError in test fixture using dumpdata --natural

[bobhaugen]

Still getting "IntegrityError: columns app_label, model are not
unique" when loading a test fixture created by dumpdata using the
keyword --natural.

I am probably missing something, but I understood the resolution to
https://code.djangoproject.com/ticket/7052 to be to use the new --
natural keyword when doing the dumpdata:
https://docs.djangoproject.com/en/dev/ref/django-admin/#django-admin-option---natural

I'm using Django 1.3.1.

So what am I missing?

Django - how to create a private subpage?

[Petey]

I am trying to do a private subpage for every user which will be accessed 
trough url:
url(r'^galeria/$', 'publisher.views.private_gallery'),

I was trying to create a query set for private gallery by using a signal: 
user_logged_in

p = Publisher.objects.filter(status='p', pub_type='private_gallery', 
user_gallery=str(user_logged_in)).order_by('-id')

However, django does not accept signals in querysets.
Could you give me some good hints on making private pages which can be 
viewed only by Users?

Re: Still getting IntegrityError in test fixture using dumpdata --natural

[bobhaugen]

Replying to myself:  temporary fix for dumpdata: --exclude
contenttypes --exclude auth.permission

The result now works as a test fixture.

Not sure what to conclude:
* the fix for issue #7052 does not work?
* --natural does not fix the IntegrityErrors with contenttypes in test
fixtures?
* contenttypes are trouble in test fixtures?
* test fixtures are trouble and I should just create all of my test
objects in the test cases?
* I am just confused?

Subject: Sample Custom Decorator

Hey Guys,

Would anyone be willing to show me an example of a very simple and
dumb decorator for views? I've been trying to read the existing
decorators and play with a couple of snippets but I'm having a lot of
trouble with two aspects -- grabbing the User Instance and Redirecting
somewhere besides Login (without making it look like a hack).

Here's some ugly pseudo-code for what I'm trying to accomplish...

# Custom Decorator
def my_decorator(function = None)

# Grab Data
request = how_do_i_get_this?
user = request.user

# Perform Logic, Redirect or Continue Normally
if user.foo():
redirect to '/foo' URL
else
display requested view?


# Decorated TemplateView
url(r'^$', my_decorator(TemplateView.as_view(template_name =
'bar.html'))),

Thanks!

Alternative to the .using() method

[Sells, Fred]

I'm using a MySQL database and one table resides in a separate database
than all the others.  It's a generic logging table.

I understand the use of the .using() method, but I wonder if there is a
way to specify the alternative model in the model definition so I don't
have to depend on remembering to add the .using() method in any usage.

I could create a view in mysql and make the model "unmanaged" but was
wondering if there is a more pythonic way?

Re: Django - how to create a private subpage?

[Kurtis Mullins]

Check out this page:
https://docs.djangoproject.com/en/dev/topics/auth/#handling-object-permissions
Also, you may want to check out decorators if the user only has to be logged
in. Another method you could use are groups.

Re: Django - how to create a private subpage?

[Victor Hooi]

heya,

I might be misunderstanding your requriements, but could you use the 
@user_passes_test decorator with a has_perm check?

@user_passes_test(lambda u: u.has_perm('private_pages.foo'))

https://docs.djangoproject.com/en/dev/topics/auth/

You can probably make the lambda a bit smarter, instead of using has_perm, 
check if the pagename matches the username.

Cheers,
Victor

Indeed there is: what you're looking for is called a "database
router", and you can find documentation here:
https://docs.djangoproject.com/en/dev/topics/db/multi-db/#automatic-database-routing

In your particular case, you'll implement something very similar to
the first example presented there: if the app is your logging app, use
the logging connection; otherwise, use the default connection.

Storing data from frequently changing forms

[Michael Wayne Goodman]

Hi all, I'm new to this and could use some help,

I'm implementing a large-ish form-based application for an ongoing
academic project. As students come and go, the form fields change
frequently, so I'm wary to have form fields map to database entries.
Does anyone have a good idea of how to store the form data? Currently
the data is serialized and the user can download/upload it from/to the
form. Perhaps I could store the serialized data in the database as one
large CharField, or I could do something more robust to change like
RDF triples?

Any ideas or comments would be appreciated.

Re: Sample Custom Decorator

[Kurtis Mullins]

Thanks Fred! I tried to look through your code and understand what's going
on -- but I'm still at a loss. I'm guessing I need to look at the Django
source to see what should be returned when you hit a URL and what is passed.
The wrapper is confusing me and I've seen that in Django code as well. I'm
going to go out on a limb and say it's probably not as easy as I hoped,
haha.

Re: Storing data from frequently changing forms

[Kurtis Mullins]

I don't know how to go about integrating Django with an RDF Store, but from
my academic experience RDF Stores were pretty popular to use when you have
constantly changing data. I'd be interested in a RDF Store project for
Django if you end up going that route.

Re: Django - how to create a private subpage?

[Matt Schinckel]

That line (p = ...) is in a view, right?

It will probably want to be:

p = Publisher.objects.filter(status='p', pub_type='private_gallery', 
user_gallery=request.user).order_by('-id')

Matt.

Re: Sample Custom Decorator

[Steven Cummings]

The wrapper that you typically see is the new function that is returned.
This usually invokes the original, given function in addition to some extra
("decorating") logic around that call. Based on that question it sounds like
you might want to check out some introductory material on decorators [1][2].

Django view decorators simply need to be able to decorate a view function or
class, which means they need to support decorating something that takes a
request and optional args and returns a response. That means your wrapper
function can specify this much of the signature, and that's how you get
ahold of the request to work with. So, based on your pseudocode:

def intercept_foos(view_func):
def wrapper(request, *args, **kwargs):
if request.user.foo():
return redirect('/foo')
return view_func(request, *args, **kwargs)
return wrapper

Then just apply it as you did in your urls.py example.

Hope this helps.

Re: Sample Custom Decorator

Thank you so much for the awesome clarification. It makes a lot more sense.
I'm going to read those docs and play around with the code just to feel
comfortable. I appreciate the great answer!

django and unicode

[Elim Qiu]

I just start try django 1.3.1, still in the step I of the tutorial,
but noticed that the tables created is in latin1 encoding while I
prefer utf8 for the entire app.

I don't want to set the database default char encoding to be utf8
since I have other non-django apps.

What is the proper way of setting utf8 encoding for django apps?

Thanks

This https://docs.djangoproject.com/en/dev/ref/unicode/

would suggest that making the table UTF8 should suffice

That will break if the DB is UTF8?

Thanks a lot Lachlan Musicman, I'll go a head to try this.

Yes. For example, Simplified Chinese typically use an ecoding GB2312,
apps using it will display utf8 Chinese as unreadable things...

Since my other apps will not share data with django, make django utf8
friendly should be enough.
