I'm building a project with Django 1.5.1 and decided to migrate the project to Django 1.8.4, then I found out I cant initialize the project, I was able to detect and fix some errors, but It's been a couple of days now and I can't figure out the rest.

The traceback is telling you that the problem is this line in your UnidadesForm model form.
ciudad = forms.ModelChoiceField(widget=forms.Select(attrs={'size':'13', 'onchange':'this.form.action=this.form.submit()'}), choices= RefCiudades.objects.filter(provincia__contains = RefProvincia.objects.filter(descripcion__contains = "CHUBUT").values("id")) )
As it's a model choice field, it would be better to use the queryset argument rather than choices.
ciudad = forms.ModelChoiceField(widget=forms.Select(attrs={'size':'13', 'onchange':'this.form.action=this.form.submit()'}), queryset= RefCiudades.objects.filter(provincia__contains = RefProvincia.objects.filter(descripcion__contains = "CHUBUT").values("id")) )
I think that might stop the error, but I'm not sure that your queryset makes sense. The filter argument provincia__contains should take a string, but RefProvincia(...).values("id") will return a values queryset.

django.db.utils.ProgrammingError: relation "swsite_hitcounter" does not exist
LINE 1: INSERT INTO "swsite_hitcounter" ("date", "template_location"...
This is confusing to me as it is specifically trying to build the swsite_hitcounter table as in the following migration I am trying to fun:
# -*- coding: utf-8 -*-
# Generated by Django 1.9.5 on 2017-07-05 15:56
from __future__ import unicode_literals
from django.db import migrations, models
class Migration(migrations.Migration):
dependencies = [
('swsite', '0022_auto_20170307_1343'),
]
operations = [
migrations.CreateModel(
name='HitCounter',
fields=[
('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
('date', models.DateTimeField(auto_now=True)),
('template_location', models.TextField()),
],
),
]
Is something maybe out of sink? This is me trying to run this migration on my production box, it ran fine (of course) on my development box. Might of been cause I ran a specific migration? :
python manage.py migrate swsite 0023_hitcounter.py
Though running:
python manage.py showmigrations
Gives me same error? I am guessing my migrations are out of sync but not being able to show migrations, I don't know how to show the ones that didn't get into this update (on production from gilab)
The traceback is showing you that the error is occuring in IndexView. You are trying to create objects in the database when the view loads.
class IndexView(TemplateView):
newhit = HitCounter.objects.create() # remove this line
...
Accessing the database when the views load like this is a bad idea, so you should probably remove the line. In production, it gives you the error because it is trying to create the object in the database before you have applied the migration that creates the table.
I have an actions.py file which defines custom actions for the admin page for one of my models. It uses an intermediary page (like the default delete action) and hence has a corresponding form which is also declared in the same file.
For some reason, I had drop by database (development) and now when I try to run syncdb, it gives me the following error:

django.db.utils.ProgrammingError: relation "iiitd_clientinfo" does not exist
LINE 1: ...ientinfo"."id", "iiitd_clientinfo"."corp_id" FROM "iiitd_cli...
iiitd is the name of one of my apps. The reason this is happening is because actions.py imports the iiitd_clientinfo model - but that doesn't exist yet, obviously. Currently, I make it work by excluding/commenting out my actions.py file. Surely, there has to be a work around?
I have tried the following:
south migration before syncdb - same error.
sorted out the INSTALLED_APPS order to ensure that they are in a topological order- same error
Used this in my actions.py:
try:
clientObj = ClientInfo.objects.all()[:1].get()
except ClientInfo.DoesNotExist:
clientObj = None
EDIT:
Relevent part of actions.py:

self._selected_action = forms.CharField(widget=forms.MultipleHiddenInput)
except ClientInfo.DoesNotExist:
raise Exception('Please add a client info object to the client')
It's mostly a wild guess until you post the source for your actions.py module, but from the traceback I assume line 16 is at the top level of your SelectUserForm class body. If so, this statement will be executed each time the module is imported, which is a BadThing for many reasons. You just discovered one of these reasons, congrats. Another one is that this will be executed once per process, and only once per process, which leads to to strange bugs as soon as you're in production (stale state, incoherent state from one process to another, etc).
The cure here is to move this statement within a method of your form.
I installed dajaxice into a django project. When i run the web using manage.py runserver, all went well. Now I try to deploy it with apache/wsgi. When I run manage.py collectstatic, error occur:
ImportError: cannot import name Bag
where Bag is one model within my app.
I tried
manage.py shell
then import Bag, i works well.
And I tried comment out DajaxiceFinder from settings.py, collectstatic finished normally.
Could any one help me out?
Thanks

from emini.repairment.models import Bag
ImportError: cannot import name Bag
Enviroment:
Django==1.5.4
django-dajaxice==0.5.5
I try to delete the import Bag from express/models.py, then collectstatic successed.
Structure of my apps:
emini
express
models.py
repairment
models.py
in emini.express.models:
from emini.repairment.models import Bag
class Package(models.Model):
foo = models.CharField(max_length=20)
class BagPackageLink(models.Model):
bag = models.ForeignKey(Bag)
package = models.ForeignKey(Package)
class Meta:
unique_together = (("bag", "package"),)
in emini.repairment.models
class Bag(models.Model):
foo = models.CharField(max_length=20)
Am i messing up with 'overlap import'?
But why the runserver and shell can import Bag model?
I have django.contrib.auth in my installed apps and everything was was working about 10 minutes ago. I deleted the existed database because I had problems with south migrations. When I try to rebuild it I get an error.
Error: django.db.utils.DatabaseError: no such table: auth_user

**django.db.utils.DatabaseError: no such table: auth_user**
The problem is that you are running a query against the User model
File "/home/bruk/workspace/hungryDroid/src/hungryDroid/Ingredient/models.py", line 26, in Ingredient
FKowner = models.ForeignKey(User, default=User.objects.get(pk=1).id)
In the syncdb process (during field declaration actually, so any time your module is imported, like during this validation process).
This will make sure that the auth_user query is executed before the auth_user table is created.
A safer way to get the functionality with the default user is to do
def get_default_user():
return User.objects.get(pk=1)
And then in your field declaration, do
FKowner = models.ForeignKey(User, default=get_default_user)
As per the model field reference default can be a callable. Note that you would have the same problem if you used get_default_user() in there - then it executes immediately, not on-demand.
I'm creating a pylons app and I keep getting an error when trying to start the app with paster. I've searched for answers on google and keep coming up with nothing. Anyone have any ideas?

I figured it out, the book i was using said to use
sqlalchemy.pool = 3600
But apparently it's supposed to be
sqlalchemy.pool_recycle = 3600
