Re: run manage.py commands within app

[Lachlan Musicman]

I use cron and a script - but would love to hear other methods as well.

Notes: Need to add virtualenv to PATH:

crontab -e

SHELL=/bin/bash
PATH=/home/erp/.virtualenvs/prod/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

#
# m h  dom mon dow   command
0 * * * * cd /home/www/prod/erp/ && python manage.py update_index
--settings=erp.settings.production >> /tmp/cronupdate.log 2>&1 &&
python manage.py build_solr_schema --filename=schema.xml
--settings=erp.settings.production >> /tmp/cronbuild.log 2>&1 && cp
schema.xml /opt/solr/erp/conf/

resistance to definition and categorisation, the anarchist principle
has been variously interpreted as, rather than an articulated
position, “a moral attitude, an emotional climate, or even a mood”.
This mood hangs in dramatic tension between utopian hope or dystopian
nihilism...

run manage.py commands within app

[judy wawira]

Hello I have a django app using haystack and a solr backend to power 
searches

There is dynamic addition of data and wonder if there are other ways to 
automatically rebuild the solr index without manually going to the command 
line to run manage.py rebuild_index

Thanks

Re: Model validation across relationships

[Simon Charette]

I'd say that's exactly what you should use `Model.clean()` for. In this 
case you're *doing validation that requires access to more than a single 
field.*

What sounds vague to you in the documentation?

[OT] How to get rid of caching completely

[Mrinmoy Das]

Hi,

This is a totally off topic question but is there a way to stop caching at
all level?

I have added

*expires -1;*
*add_header Cache-Control "private, must-revalidate, max-age=0";*
*add_header Last-Modified "";*

this on my nginx server block, but there are still some caching are
happening.  Any way to get rid of that completely. :)

Re: loaddata not looking for natural keys

[bobhaugen]

Ok, now I am really confused.

Here's the code where the error originates in 
django/core/serializers/python.py:

   # Handle FK fields
elif field.rel and isinstance(field.rel, models.ManyToOneRel):
if field_value is not None:
import pdb; pdb.set_trace()
if hasattr(field.rel.to._default_manager, 
'get_by_natural_key'):
if hasattr(field_value, '__iter__'):
obj = 
field.rel.to._default_manager.db_manager(db).get_by_natural_key(*field_value)
value = getattr(obj, field.rel.field_name)
# If this is a natural foreign key to an object 
that
# has a FK/O2O as the foreign key, use the FK 
value
if field.rel.to._meta.pk.rel:
value = value.pk
else:
value = 
field.rel.to._meta.get_field(field.rel.field_name).to_python(field_value)
data[field.attname] = value
else:
data[field.attname] = 
field.rel.to._meta.get_field(field.rel.field_name).to_python(field_value)
else:
data[field.attname] = None



Here's what pdb says:

(Pdb) p field

(Pdb) p field_value
u'Cash Contribution'
(Pdb) p hasattr(field.rel.to._default_manager, 'get_by_natural_key')
True
(Pdb) n

(Pdb) p field_value
u'Cash Contribution'

I thought unicode fields had iterators? But here's one in ipython:

In [15]: field_value = u'Cash Contribution'

In [16]: field_value.__iter__()
---
AttributeErrorTraceback (most recent call last)
