Re: django-celery connects to localhost but not by ip

[Chad Vernon]

Thanks, I found the issue after checking the logs.

I saw in the log that it listed the AMQP connection that it accepts:

=INFO REPORT 19-Sep-2013::20:52:57 ===
accepting AMQP connection <0.403.0> (127.0.0.1:59930 -> 127.0.0.1:5672)

So if that is stating the obvious, I assumed it was blocking all other ips. 
 So I found this page 
http://superuser.com/questions/464311/open-port-5672-tcp-for-access-to-rabbitmq-on-mac
and removed NODE_IP_ADDRESS from rabbitmq-env.conf and that seems to work. 
 But I guess my first assumption was incorrect about what the log displayed 
because when I run the command again, the log just says my machine 
connected and displays the port range of that ip address.

However, one issue that still is strange is that the ASyncResult returned 
from the task always seems to return False from the .ready() method even 
though it seems to have completed the task.  Any ideas on that?

Re: django-celery connects to localhost but not by ip

[John DeRosa]

First things to check:

Check the firewall on the RabbitMQ server. Can you access that server?

Did you set up the vhost and account on the RabbitMQ server?

Look in the RabbitMQ logs. Did the request make it to RabbitMQ?

django-celery connects to localhost but not by ip

[Chad Vernon]

I am using djcelery and rabbitmq.  Everything runs fine when the
BROKER_HOST is localhost but when I change it to the ip of the machine it
no longer runs.

Basically I am trying to be able to run python commands on a separate
machine to be picked up by the RabbitMQ server on a different machine.  But
to test first I am doing it all on the same machine.  But as I said it
doesn't seem to work when I change from localhost to the machine ip. I just
get socket.error: [Errno 61] Connection refused.

Any ideas?

The thing is -- your question is wrong, and until you understand *why* it's
wrong, you're going to be frustrated with Django's ORM.

Django's ORM *isn't* SQL. It's an object model. The ORM *very deliberately*
avoids exposing SQL concepts. Asking "How do I do a GROUP BY" is the wrong
question to be asking. There *is* no way to do a GROUP BY in Django's ORM -
and that's by design.

What we *do* have is two things:

Firstly a representation of common object-based summaries, expressed in
object terms. What is the average age of this group of authors? What is the
total sum of the value of all books written by this list of authors.
*These* are object-based queries, not GROUP BY statements. You need to pose
your question in terms of the relationships between objects in order for it
to be meaningful.

Secondly, we have a fall through that will give you access to raw SQL. An
ORM is an abstraction, and all abstractions leak, so sometimes to get the
most efficient representation of a query, you'll need to go to the bare
metal.

So - there's actually no way to answer your question. If you have a
specific query you want to represent, we can help you work out how to
express that in the ORM, but asking "how do I GROUP BY" doesn't make any
sense.

Yours,
Russ Magee %-)

About the only meaning that "logout" can have on a web site is "this

Re: migrating from django 1.3.0 to 1.5.4, getting ImproperlyConfigured exceptions (AUTH_USER_MODEL refers to model 'auth.User' that has not been installed)

[Leonardo Giordani]

The way you are creating the DB is quite complicated, but I suspect that
you are not syncing the base Django applications before doing your magic
stuff. That could be the reason why Django is complaining about the
auth.User not being installed.

I would do the following:

* settings.py with the core apps
* syncdb
* inspectdb
* schemamigration --auto
* migrate

I strongly feel that your problem has to do with Django processing your
models BEFORE doing the base stuff.
Can you try this?

Leo

You are using self.loan_amount, which is an attribute, as a function:

Re: migrating from django 1.3.0 to 1.5.4, getting ImproperlyConfigured exceptions (AUTH_USER_MODEL refers to model 'auth.User' that has not been installed)

[Lauri Carpenter]

Ok, I have found the problem (through digging through to post more 
information about it).

It turns out that in our gui application, the gui-specific settings file 
was setting:
INSTALLED_APPS = (
'ncis_gui',
'ncis_sslauth',
'django_auth_ldap',
)

and did not include the apps that come by default with django.  When I fix 
this to contain the full list,
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'ncis_gui',
'ncis_sslauth',
'django_auth_ldap',
)

things started to work again.

Thank you for helping me to walk through all of this.  Now I wonder why 
this is working at all in django 1.3.0, but at least I know how to move 
forward to make it work in django 1.5.4!

Thanks much, lauri

Re: migrating from django 1.3.0 to 1.5.4, getting ImproperlyConfigured exceptions (AUTH_USER_MODEL refers to model 'auth.User' that has not been installed)

[Lauri Carpenter]

More information: 

Interactively, I can get a user_model:

$ python
Python 2.6.6 (r266:84292, Oct 12 2012, 14:23:48) 
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from django.contrib.auth import get_user_model
>>> user_model = get_user_model()
>>> user_model

>>> 
>>> 
>>> from django.conf import settings
>>> settings.AUTH_USER_MODEL
'auth.User'
>>>

(note that the settings.AUTH_USER_MODEL is being calculated by django, not 
set by us; our settings.py file does not include any reference to 
AUTH_USER_anything).

But when this happens during the authentication portion of the web 
interface, it causes the traceback, from somewhere within the 
django.contrib.auth forms for logging in (see traceback in initial 
posting).

Receive parameter via post

[Hélio Miranda]

Good.
I have my client application server, and was trying to send an id parameter 
via a post like this:
$scope.deleteIMG = function(ID){
 $http({
method: 'POST',,
url: "http://localhost:8080/onpitch/delImagePlayer/;,
data: {id:ID},
headers: {
"Content-Type": "application/json; charset=utf-8"
}
}).success(function(data){
console.log(data);
});
}

My issue is that now I do not know how to get the id on the side of Django.
Someone can help me?

Re: Exception Error

[Leonardo Giordani]

Ok, can you report the content of

Your error is there.

Simply paste the output of "nl models.py | grep 264 -C 20"

DatabaseError during executing in ibm_db_dbi.py

[Dennis Jade Toribio]

Hi,

i am new to using DB2 in Django. So far, my problem was with using 
ibm_db_django adapter as I see it. Since using ibm_db has no problem 
saving/getting data.

I was wondering what causes the problem here. It seems to me the 
*execute*method inside ibm_db_dbi.py => _execute_helper =>  return_value = 
ibm_db.execute(self.stmt_handler, parameters) cause the error not really 
100% no idea :) as this is my 3rd with db2-django :(

Re: migrating from django 1.3.0 to 1.5.4, getting ImproperlyConfigured exceptions (AUTH_USER_MODEL refers to model 'auth.User' that has not been installed)

[Lauri Carpenter]

I don't think we used a custom User model in Django 1.3, but perhaps we did 
without knowing it.  How would I know for sure?  We aren't setting any 
AUTH_USER_*** anything in our settings file, that's certain.

- We use django-admin.py syncdb to create the authentication tables and 
whatever else is needed for the INSTALLED_APPS, where our installed_apps 
looks like:
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
)

The tables created are:
Creating table auth_permission
Creating table auth_group_permissions
Creating table auth_group
Creating table auth_user_groups
Creating table auth_user_user_permissions
Creating table auth_user
Creating table django_content_type
Creating table django_session
Creating table django_site

- We do not use django to generate our database, we use a different tool 
(dezign).Dezign generates a "create_db.sql" script from an ER diagram. 
 A Makefile runs the "create_db.sql" script to create the tables after the 
original django-admin.py command has created the initial administrative 
tables.  We add one foreign key constraint to one of our tables 
(client_certificates.user_id references auth_user.id). 

- We use django-admin.py inspectdb (plus automated massaging of that 
output) to generate the models.  Our models do include classes all of the 
admin tables listed above.

So, are we using the django user model, or a custom model?  I would think 
we are using the django user model, but...

session data and logout

[MikeKJ]

I have this oddball requirement where an authenticated user is logged in so 
I can create a session variable to use elsewhere then do logout(request),so 
far so good, but it appears that my session variable is destroyed by the 
logout.  
Now I honestly thought that this wouldnt be the case as in settings.py I 
use the session expire on browser close.
Anyone have any insight they can offer as to why the session variable os 
deleted and how to overcome it and retain the value?

Cheers

As an image map is simply HTML interpreted on the client side,  Django
doesn't handle any image map, the browser does. Use any tool you like
to generate the image map polygons.

Fixing missing permissions (not in contrib.auth.models.Permission table in db)

[graeme]

As far as I can see the permissions should be there. I checked the South 
migration I used to add the Model and it seems correct: the schema 
migration creates the table and then 
calls db.send_create_signal('managed_villas', ['GuestReview'])

How do I fix it? The ContentType exists and seems correct, and everything 
else I can think of seems OK, except for the missing permissions:

i.e. Permission.all() does not included the expected permissions.

Should I fix by manually creating the permissions, or is there a better way?

Problem with authentication middleware, session and cache

[Alessandro Pasotti]

Hi,

I' have some problems trying to cache most of my websites when
 authentication mw is in place.

I only want to  cache anonymous users:

CACHE_MIDDLEWARE_ANONYMOUS_ONLY = True

anyway, I also want to show a different menu to authenticated users, so I
also check for user.is_authenticated in a template tag for the menu.

It seems like like this check accesses the session and the mw then sets
Vary=Cookie in the response, this prevents caching for users even if they
are anonymous.

To make things more complicated I also need to use sessions in a few view
(which are of course not cached).

Any suggestion about how to allow caching of my pages for anonymous users?

Re: add marks of same roll number of different of different semestrs

[Lachlan Musicman]

I will presume that you have 2 Student details with the same roll_no
but with different class numbers. If that is not the case, then you
will need to revisit the modelling of your data.

Anyway, something like this would work.

student_details = StudentDetail.objects.get(roll_no=)


for student_detail in student_details:
 

Does that make sense? This would work in the shell, but for a
template, you would need a view for the first bit, and the second in
the template.

cheers

Preview video

[Hélio Miranda]

Good staff.

I'm here with a problem which is: I'm uploading videos and now wanted to 
show the video, but not sure how. I have to use a player?
Someone can help me.

For example the images I'm uploading and then viewing the'm doing something 
like this

def viewAcademyPhotos (request, id):

 mongoengine.fields.GridFSProxy = fs ()
 fs.get picture = (id = ObjectId (id)). read ()

 return HttpResponse (photo, content_type = 'image / jpeg')


In the videos, how about it? Change the *content_type* for eg *video / avi*

Re: while loop in django

[Leonardo Giordani]

Harjot,

with so little information is very difficult to help you, you should try to
give a description of your models and exactly what you want to do. What are
the "values" and the "job-id" you are talking about? And what about
"differences"?

About the while loop: in Python it is used this way
http://anh.cs.luc.edu/python/hands-on/3.1/handsonHtml/whilestatements.html
In Django views (being them Python) you can do the same. In the Django
Template Language there is no while loop available. You can write a tag on
your own, but I suggest you to try and clarify your issue, so that we can
come up with a solution.

Regards,

Leo

Re: Need help figuring out why my { key:value } doesn't seem to be passed to my view by my javascript file.

[Leonardo Giordani]

In Django key:value are sent the way you specify in your urls
configuration. E.g., say that you want to show an object that you can
extract from your DB with year=2013 and month=09 ('year' and 'month' are
here a primary key for that model if used together). The URL schema is
completely up to you, so you could implement the following solutions

basepath/2013/09/
basepath/2013_09/
basepath/?year=2013=09
etc, etc

You have just to implement the correct regular expressions in your URL
specification. (I would strongly adverse the second and the third example,
I used them only to exemplify what you can do).

This is what happens with standard GET requests in your views. POST
requests follow the same schema, but they encompass the form data in the
POST section of the HTTP request (that is available through
self.request.POST in your view).

So the problem you have to figure now is: what is jQuery.ajax() doing?
Sorry but I do not know jQuery AJAX, so I cannot help you on this topic.
Reading the documentation I understand that it is issuing a GET on
"/pi/?pathID=somevalue", so I would implement an URL pattern and a view to
catch this request.

Let me know what happens. Regards

Leo

Re: migrating from django 1.3.0 to 1.5.4, getting ImproperlyConfigured exceptions (AUTH_USER_MODEL refers to model 'auth.User' that has not been installed)

[Leonardo Giordani]

A question to better understand your problem: do you use a custom User
model in Django 1.3?
Did you perhaps set the AUTH_USER_MODEL=auth.User in your settings.py?

If you do not need a custom user model just drop the AUTH_USER_MODEL
setting variable. Otherwise subclassthe AbstractBaseUser and set your
application's user model in the settings.py file.

Let me know if I correctly understood your issue.

Re: while loop in django

[Leonardo Giordani]

Can you perhaps better describe what you are trying to do?
Do you need it in a view or in a template?

Re: Using environment variables in settings.py - good practice? How to handle missing variables gracefully?

Hi,

Hmm, in many cases there isn't really a sensible default (e.g. API keys
or passwords).

I was asking more in terms of - is this the "right" way of doing it in
Django, or are people using some other technique to handle configuration
you don't want in the repo?

And is there a special exception type you should throw if it's not being
set, or is there a better way to handle it?


Well worth checking out Two Scoops of Django - it has half a chapter on 
exactly this topic. In summary, the authors say to use environment 
variables and to raise ImproperlyConfigured if they don't work.




Cheers,

Hi,

   Do you means some thing like this?

os.environ.get('SOME_VARIABLE', 'default_value')

Hi,

I have several settings in my Django settings.py file that are
specific

Currently, I'm grabbing these from environment variables in
settings.py:

import os
...
# TODO - We need to gracefully catch if these aren't set.
SOME_VARIABLE = os.environ['SOME_VARIABLE']


This includes things like API keys, database IPs, database
username/passwords, static file locations etc.

I then set these in the virtualenv activate script.

Is this a good practice in Django?

Also, is there a graceful way of catching when these aren't set?
Currently, I'm using some of those settings variables in
models.py, and it's failing silently. Should I put each
os.environ call in a try/except block, or is there a more
Pythonic way?

Cheers,
Victor
