Re: Serving static files (admin panel and others)

[Muhammed Tüfekyapan]

I find the problem. 


Problem was the file dir nginx looking for static file is different than I 
used for static file.

I changed the files location and it solved.


Thanks for response.

django template auto format tool?

[Abraham Varricatt]

Hello,

Is there any command-line based tool which would let one auto-format Django 
template files? Ideally, the tool should also be used to format HTML, CSS 
and .JS files too. 

I've recently inherited a bad-looking code base and want to clean it up. 
Have heard of the PEP8 autoformatter, but that just works for Python files, 
right?

-Abraham V.

How to toggle/set boolean-values of multiple records in the Admin?

[inoyon artlover KLANGRAUSCH]

Hi there, 

my model is:

class ZipCode(models.Model):
zipcode = models.CharField(max_length=5)
city = models.CharField(max_length=255)
active = models.BooleanField(default=False)

I would like to mange the 'active' status of some entries in the admin by 
selecting multiple.
For example: I select 20 entries and than toggle or set the 'active' status 
to True/False.

Many thanks in advance. Cheers :)

Re: Django + Raspberry PI

A bit dated, but since this page came up when I ran into the same issue,

Pretty much I turned off DEBUG in the settings.py file, and the performance 
is fine now = )

Django 1.7: How to migrate data between two external apps

[John-Scott]

Say I decided to switch from a third party app foo-tags to app bar-tags. 
Their Tag models are mostly identical so I just need to move the data from 
foo-tag to bar-tag. Since I don't control their migrations, I'd need to 
create a migration in one of my own apps:

./manage.py makemigrations my_app --empty

In this migration I'd need to explicitly list the dependencies on these 
external apps (otherwise was getting errors that the foo and bar apps were 
not available in the app registry):

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.db import models, migrations

def migrate_tags(apps, schema_editor):
FooTag = apps.get_model('foo_tag', 'FooTag')
BarTag = apps.get_model('bar_tag', 'BarTag')
for old_tag in FooTag.objects.all():
new_tag = BarTag.objects.create(name=old_tag.name)

class Migration(migrations.Migration):
dependencies = [
('my_app', '0001_initial'),
('foo_tag', '0001_initial'),
('bar_tag', '0001_initial'),
]

operations = [
migrations.RunPython(migrate_tags)
]


The migration itself works as expected. However if I now remove foo_tag 
from INSTALLED_APPS, Django will now give an error:

KeyError: "Migration my_app.0002_auto_20141212_1951 dependencies reference 
nonexistent parent node ('foo_tag', '0001_initial')"

What's the correct way to handle migrating data between 3rd party apps 
where one of the apps is eventually removed?

Thanks,
John-Scott

Re: Need to search through several tables using one model

[Alon Nisser]

You could also create a model that foreign keys to all the relevant models, 
and filter on that.. 
Buy first you need to clarify (for your self..) The exact use case: is it 
search? if so better use haystack with some search backend (elasticsearch 
would be a great choice), Is it to choose something in a form? something 
else? 

The technical details should be derived from the problem you are trying to 
solve..

Re: Django-compressor manifest.json problem on Heroku

Can I override the search button, so it will call the custom raw query ?
And if yes, can you show me how to override it, please ?

Re: Seeking for advise on usage MySQL together with MongoDB

Hi Cal,

> DRF has it's own problems and (again imho) does not solve the problems it 
was originally designed to fix. Attempting to build anything beyond "out of 
the box CRUD" requires hacky/unclean workarounds, with most of your time 
spent fighting against the shortcomings of DRF rather than working with it.

I'm slightly at a loss to understand what set of pain points could have 
left you with that impression, but it'd be helpful to get a better idea.

Perhaps some of the awkwardnesses in 2.x serializers that have been 
addressed with the 3.0 release?
Perhaps a misunderstanding that viewsets/routers are intended to be the 
canonical way to use REST framework?

The 'build anything beyond "out of the box CRUD"' comment is particularly 
surprising to me because of all the work I do in REST framework *none* of 
it is CRUD, and the design decisions in REST framework are very explicitly 
towards it being an agnostic Web API toolkit, that just *happens* to also 
have easy support if basic CRUD stuff *does* happen to be what you want. Eg:

* Validation that's cleanly decoupled from Django's ORM, but that can also 
work seemlessly with it if that's what you need.
* Works just fine with regular views, but has a minimal set of pre-provided 
generic views if simple CRUD operations are what you need.
* Viewsets and routers for projects that fit well with a very standard URL 
style, or drop down to views and explicit URL conf otherwise.

I don't want to jump on and just criticize the view point you've presented 
- whatever it is that's left you with that impression is clearly a useful 
data point for me.

What other API toolkits would you look towards as more mature, well 
supported, nicely designed solutions?
Which shortcomings were you fighting against, and what do you think the 
project should be doing differently?

Cheers,

  Tom
