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

Am i messing up with 'overlap import'?
But why the runserver and shell can import Bag model?

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.
Im trying to write simple application with this project structure:
website (root directory)
..mainws (its app)
....migrations(not filled)
....usermodels
......__init__.py
......Role.py
....__init__.py
....admin.py
....models.py
....test.py
....views.py
..website(directory for project)
..manage.py
And after making project, I created mainws app, when wrote for Role table. Also added in models.py (directory mainws):
from usermodels import Role
But using in terminal "manage.py sqlall mainws" giving for me big stacktrace (mainws app added at the and of INSTALLED_APPS). How can I fix this trouble?
Role.py contains code:
from django.db import models
class Role(models.Model):
role_name = models.CharField(max_length=25)
def GetRoleName(self):
return self.role_name
def SetRoleName(self, new_role_name):
if self.role_name != new_role_name:
self.role_name = new_role_name
Stacktrace:
=> python manage.py sqlall mainws

Do the following changes :
1) Rename your usermodels folder to models folder(for simplicity).
2) In the __init__.py file of models folder, import the Role model using from . import Role.
3) leave the models.py file(of the outer directory) blank.
So ultimately you will have the following structure
website (root directory)
..mainws (its app)
....migrations(not filled)
....models
......__init__.py
......Role.py
....__init__.py
....admin.py
....models.py
....test.py
....views.py
..website(directory for project)
..manage.py
Then run the sqlall command.It should work!
In one of my django 1.6 apps, SOME_APP, I attempt to hook up a tastypie signal so that I can have API keys generated on User creation, as in the tastypie docs:

What is causing this error and how can I fix it?
Thank you for any thoughts and suggestions :)
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:

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 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.
