Your regular expression is bogus. Presumably (given the error messages
I've chopped) that URL is in a urlconf that has a prefix of
"/plugin/", so ignore what Tom Lockhart said about that.

Your regexp is:

r'^(?P\D+)/$'

This says "From the beginning of the string, capture a grouping of 1
or more characters from the class '\D' as the parameter 'pluginTitle',
followed by a '/' character, followed by the end of the string.

The main problem is that there is no such character class '\D'. There
is '\d', it means the digits 0-9, but you are trying to match the word
'title'. Work out what are valid characters for your title and write
the regular expression accordingly.

Cheers

Tom

Re: AttributeError: 'module' object has no attribute '_handlerList'

[Leonardo Giordani]

As I suspected, there is a problem with the logging module, which is
probably shadowed, i.e. when Django performs "import logging" it imports a
different module.
Try the following: exactly where you execute the manage.py open an
interactive Python shell and do

>>> import logging
>>> print logging.__file__

This should hopefully show us what logging is working behind the scenes.
Try and post the results

Leo

 Please give me the information I asked you, otherwise I cannot figure
 out what kind of problem you have.

 Are you using a virtualenv? In that case, can you post the list of
 packages you installed? If not, can you give details about the OS you are
 working on?

Re: def altword_list(self, request, word_id):

[Pepsodent Cola]

Hi Leo,

get_query() function in class AltwordlistView which I refer to as
*Filter-5*didn't give me the ordered list result that I wanted.  So
somebody on
#django IRC helped me to fix that problem by giving me
*altword_list()*function which I refer to as
*Filter-8*.
You can basically ignore all the other Filter codes but I left it there in
case it might help you see what I'm trying to do.

My main focus right now is to connect the Filter-8 code to my template *
altword_list.html* but I don't know how to do it.

django cron job - stops after reading some portion of huge file - why is this?

[doniyor]

I am reading file from url and parsing it and saving some information out 
of this file into db - using cron job. 

i am testing now in my local dev. 

the problem is: job is reading file and saving into db without any problem 
but after some time, since file is very huge approx. >8GB, job doesnot do 
anything and freezes, without giving any error, 

i am using django 1.4, python 2.7 and postgresql. is there any limit for 
writing into db? why is it freezing?

Django data to Javascript

[drakko]

Hello!

I'm new to Django and Javascript and so I need some help with passing list 
from django template to Javascript.

The list is available in template (template.html) by using 

{% for shbf in should_have_found_list %}


but I have no idea how to access this list from Javascript.

The should_have_found_list is created in context.py file like:

should_have_found_list = ShouldHaveFound.objects.filter(enabled=1)


and passed to template in view.py as a part of dictionary:

return render_to_response(template_name, RequestContext(request, {
>
> 'form': form,
>
> 'fields': simplejson.dumps(form.field_mapping),
>
> }))
>
>
I would appreciate some guidance :)

Thank You,
Drakko

Re: New to Django cannot figure URLpatterns

[Bill Freeman]

Actually, there is a character class \D; it matches any NON-digit.  As such
this should match title, as long as it contains non digits.

But looking at this line from the error message:

  8. ^plugin/ ^(?P\d+)/$ [name='detail']

It appears that you are actually using the little \d, contrary to the url
pattern that you quoted.  That would only match titles that were composed
entirely of digits.

Be sure which one is there.

You may actually want \w, or even [^/].

Bill

Re: django cron job - stops after reading some portion of huge file - why is this?

[Bill Freeman]

One possibility is that your code keeps all that is read (or something
derived from it) in memory, and you are running out.

E.g.; Is your database code trying to do all this in a single transaction?

Another possibility is that something in the file at that spot triggers a
but in your code that contains an infinite loop.

There are other possibilities.  But there's no diagnosing it with the
information you've given.

Can you, in python, read through the file, doing nothing with the data?
E.g.:

f = open('your/file/path/here')
n = 0
s = True
while s:
s = f.read(1024*1024)
n += len(s)
print n
print 'done'

That should work.  If not, does your O/S not correctly handle files that
big?

Bill

Re: readonly_fields depending on request

[Roberto López López]

Hi Timothy, thanks for your advice.

I'm sorry, I've been quite busy lately on other stuff so I had to leave
this apart. You are right, maybe I am overcomplicating things. I have
simplified my code to:

def get_readonly_fields(self, request, obj=None):
if not request.user.groups.filter(name__exact='administration'):
return ('is_featured', )
return ()

That should make the "featured" checkbox read only for those users not
in the administration group. But it doesn't, when the flow reaches the
line /return ('is_featured', )/, the user can check/uncheck the box in
the admin interface. Do you see any flaw here? Thanks again!

Roberto

Re: django cron job - stops after reading some portion of huge file - why is this?

[doniyor]

yes, db code is doin all these calls in single transaction, i mean, i am 
not using transactions, may be this is the reason? 

this is my cron code: http://pastebin.com/Lrym1z8E i know, very ugly code, 
it is saving at least some objects into db

this is url where i am reading my xml file from: 
http://www.bookatable.com/feed.aspx?channel=524&secret=10F70A84-76D7-C56C-2350-779A1A849819&language=de-DE&type=restaurants

also i noticed now that in db, there are objects whose some fields are not 
fully filled out even if the xml file does have those information. it 
means, this is a transaction issue, right? 

could you please take a look at the code? would transaction solve this 
issue?

Re: django cron job - stops after reading some portion of huge file - why is this?

[Bill Freeman]

Yes, you should split the db activity into sensible transactions, since
information about how to roll back is being stored somewhere (though some
DBs may not have a problem with this.

You've added a whole new dimension when you say that this data is not, in
fact, a local file that you are reading, but a network request.  There are
many more things between you and the data source that could have trouble
with the large data size.  I suspect that the most likely is that the
server limits the time allowed for the request to complete.  Hopefully a
server with such a limit provides for restarting the transfer from other
than the beginning.

I'm sorry, but I don't have the spare cycles to debug this for you.  Try
instrumenting things to confirm whether it is a read on the source that is
hanging or something else.  Since it's hard to get data from a hung
process, this requires some imagination.  You could write to a file an
indication of the point in the code when you are about to read the source,
when the source completes, when you are about to talk to the database, when
that completes, etc., but note that you must close the file after each
write (and open it anew before the next) since otherwise the write may be
buffered in the process when it hangs.  All those opens and closes will be
slow, so if you feel adventurous, a write to a piece of shared memory,
shared with a monitoring process, might be better.

If you find something other than the read on the source not returning,
write again and I, or someone else, with think with you some more.

Re: Defining new project as a service at nignx

[Roberto López López]

Hi Muhammed,

I agree with Javier: a django project is never run. In your case it is
deployed on gunicorn, which reads/interprets your source code. But it's
never started as a service. You can run nginx as a service, though.

You can embed js anywhere in your template, e.g.:

{% for shbf in should_have_found_list %}

my_js_function(shbf);

{% endfor %}

I think you meant to write:

my_js_function({{shbf}});

Another take on this, should you need it, is to send JSON directly over 
from the django view or model method into the template. Here's how I solved 
that recently:

importance_options = json.dumps(dict(BundleNode.importance_options))

That will convert a Django queryset into a JSON object. Then, in your JS 
template, something like:

var $options_obj = {{importance_options|safe}};

Season to taste.

Re: Django data to Javascript

[Bill Freeman]

I'd probably put the script tag outside the for loop.

But I don't see where you're passing should_have_found_list to the
context.  If it's an item (top level) in form.field_mapping, then it needs
to be something like:

  ...
  {% for shbr in form.field_mapping.should_have_found_list %}
  ...


I don't understand why you are JSON encoding form.field_mapping for the
fields template variable.  There could be perfectly valid reasons.  But if
that was supposed to make should_have_found_list available in JavaScript,
it could work, but you would have to do something with the fields variable
inside a script tag, such as use it in a var statement to initialize a
variable (var fields = {{ fields }};), and then dereference it in JS.

ImportError: cannot import name actions

[rok]

I have recently been testing the 1.6b4 tag with a new app we are writing, 
using apache and wsgi. However, I could not get rid of the following issue 
happening on every request:

Switching to 1.5.4 resolves the issue as well (even though the sites.py

Any clue?

Best Practices/Examples/Working Demos For Adding Form Fields With Ajax?

[Casey Havenor]

I'm using Django 1.4.4 FINAL, crispy-forms with bootstrap 2.0. 
I have a very large form.  
I have sections within that form where I need the user to be able to add 
additional forms based on their needs.  (Button add another xyz form).
I still need validation to work with with this new fields.
I also need the CSRF not to break. 
I don't want to reload the entire form.

What are the best practices when trying to accomplish this?

I've looked around on Google but a lot of the examples are either out of 
date or don't work.   Perhaps I'm goggling the wrong search terms? 

Thanks for your help.

SQL cast for custom model lookup

[Aryeh Leib Taurog]

I'm working with 
and I'm wondering if there's a way to get django to add an explicit 
cast to the SQL generated for field lookups.

I have a model that looks like this:

class Floats(models.Model):
arr = FloatArrayField()

Which translates to the following table definition in postgresql:

CREATE TABLE "dbarray_floats" (
"id" serial NOT NULL PRIMARY KEY,
"arr" double precision[]
)
;

When I evaluate something along these lines:

Floats.objects.filter(arr=[3.0, 9.0])

I get the following error:

DatabaseError: operator does not exist: double precision[] = numeric[]
LINE 1: ...ROM "dbarray_floats" WHERE "dbarray_floats"."arr" = ARRAY[3
 ^
HINT:  No operator matches the given name and argument type(s). You might 
need to add explicit type casts.

It looks to me like psycopg2 is for some reason presenting the query 
parameter as numeric[], so I would need to somehow slip a type-cast 
into the SQL statement so that the WHERE clause would look something 
like this:

'WHERE "dbarray_floats"."arr" = %s::double precision[]'

But there doesn't seem to be any mechanism for a custom model field to 
influence the way its placeholders are presented in SQL statements.

Interestingly, this is not a problem when saving array data, only 
when performing lookups.

Is there any way either to get psycopg2's data adapter to present the 
query parameters as double precision[] instead of numeric[] or to put 
an explicit cast into the SQL, without rewriting django's sql 
compiler?

I'm using Django 1.3 with psycopg 2.4.1 and PostgreSQL 9.1

Please cc: me on replies.

Regards,
Aryeh Leib

dates DateQuerySet includes time

[Chad Vernon]

I'm trying to use the dates QuerySet method but I am getting different 
values in the template:

view:
timecards = Timecard.objects.all()
dates = Timecard.objects.dates('date', 'day', order='DESC')


template:
{% for tc in timecards %}
  {{ tc.date }}
{% endfor %}

Oct. 14, 2013

{% for d in dates %}
  {{ d }}
{% endfor %}

Oct. 13, 2013, 5 p.m.

The documentation says dates is supposed to return a datetime.date object, 
so there should not be any time.  So where does the 5 p.m. come from?  Also 
I'm assuming the day difference is due to time zone which comes with time. 
 So am I using the dates method correctly?

Thanks,
Chad

Re: dates DateQuerySet includes time

I'm using django 1.5.1 and I guess in in 1.5, the dates method returns 
datetime objects.  So nevermind!

Re: deploy ?

[Diogene Laerce]

You can use nxinx with uwsgi even with several domain names, nginx 
takes care of that, you just run several uwsgi/gunicorn processes on 
different tcp ports or unix sockets, and nginx will just select the 
one that fits for its domain name (set in config) of course you need 
to set it properly..


Anyways, when you want to host multiple python sites with 
nginx/something, I'd recommend uwsgi with supervisor .. which will 
help you manage the apps really easy ... of course you can use 
gunicorn instead of uwsgi ... it is up to you ...


So I will go for : nginx + uwsgi + supervisor + django !


Ok everything runs fine now ! Except :..

If I well understood uwsgi is supposed to update every code changes so
that I don't need to restart the all bundle but it still does not work : 
I do

need to restart everything ? Actually I need to kill all processes first and
after restart everything ?

/debian squeeze + nginx 1.2.1 (extra package) + uwsgi 1.9.18.1 +
supervisor 3.0a.8/
