Re: Cant Import mysite.urls

[Jon Blake]

Hi Patrick,
  just got Apache + mod_wsgi to serve part 1 of the tutorial as per Django 
document "How to use Django with Apache and mod_wsgi". Your point taken 
about assuming things are going to be harder than they actually are - my 
redo of part 1 of the tutorial worked pretty well "out of the box" after a 
good night's sleep.

Now to get serving the admin files to work...

Re: How to Set Up for Apace and Mod_wsgi

[Jon Blake]

I'm not making any progress on this. I have redone part 1 of the Django 1.4 
tutorial, and it all works nicely with my Oracle back-end database and the 
development server. I'm now trying to progress this app to be served by 
Apache + mod_wsgi. After starting Apache, command  httpd -M lists 
wsgi_module (shared), and syntax OK. URL http://localhost/ shows the 
expected Apache test page.

I have added directive 

> WSGIScriptAlias / /home/jon/djangodemo/mysite/mysite/wsgi.py to 
> /etc/httpd/conf/httpd.conf
>
as per one example of setting up a production site server I have found, and 
restarted Apache. I've made no changes to my app's wsgi.py module at this 
point. Now, URL http://localhost/ displays a "500 Internal Server Error" 
page. The Apache error_log includes line:

> ImportError: Could not import settings 'mysite.settings' (Is it on 
> sys.path?): No module named mysite.settings
>

Any suggestions on how to get this working? There are a number of articles 
out there on how to set up a Django app for serving by Apache + mod_wsgi, 
with different instructions - confusing. I'm after a the simplest approach 
on to how to get my Django tutorial app running from a production server.

Any advice appreciated! My background is Oracle DBA/development + Python. 
Very little experience with configuring Apache.

Regards,
  Jon

Re: Cant Import mysite.urls

[Jon Blake]

Thanks, Patrick. My reference to utils.py should have been to urls.py, 
which I have in my mysite app package.

I'm seeing this import error on mysite.urls when I'm attempting to get 
Apache + mod_wsgi to serve my app. I don't remember seeing this error with 
the development server when I first tried out the tutorials. Probably got 
my configs wrong, somewhere in my second try.

I'll start a new app, now that I know a little bit more about how this all 
works. It's a steep learning curve!

Cant Import mysite.urls

[Jon Blake]

Working through getting Django to work with Apache, mod_wsgi and Oracle 
database back end. When I enter my site URL, I get a "ImportError at /" 
page, with an exception value of "No module named mysite.urls".

Part 3 of the tutorial refers to line ROOT_URLCONF = 'mysite.urls', which I 
have in my settings.py module. I don't have a file mysite.urls. The 
tutorial then goes on to discuss editing utls.py, (which I do have) and 
states that Django will load this module (utils.py) because ROOT_URLCONF 
points to it. I don't understand that bit - what's the connection between 
mysite.urls and utils.py, and how does Django import mysite.urls if it does 
not exist?

TIA,
  Jon

Re: Django Tutorial

[Jon Blake]

Hi David, you might have stumbled over a problem I had when I first tried 
out the tutorial a week ago. I'm using an Oracle database back end, and on 
my first try of python manage.py syncdb, I also missed the prompt to create 
a superuser account. The problem was finally identified as a missing 
privilege for my identified database account. After granting missing 
privileges, and starting again, everything was fine. 

What back end database are you using? Is dictionary DATABASES in 
settings.py correctly edited for your installed database and user account? 
Does the account have required privileges to create objects in your 
account's schema? 

HTH, Jon

Can't Find libclntsh.so.11.1 With Oracle Backend

[Jon Blake]

I have worked through the Django tutorial parts 1 and 2 with an Oracle back 
end using the development server. Everything worked fine. I now want to use 
a real server - Apache + mod_wsgi. I've got to the point where I get an 
"Improperly Configured at /" page, which shows the following:

Exception Type: ImproperlyConfigured
> Exception Value: Error loading cx_Oracle module: libclntsh.so.11.1: 
> cannot open shared object file: No such file or directory
> Exception Location: 
> /usr/lib/python2.7/site-packages/django/db/backends/oracle/base.py in 
> , line 46
>

Line 46 raises exception ImproperlyConfigured on a try block which imports 
cx_Oracle.

cx_Oracle is properly installed. In my desktop environment:

$ python
> >>> import cx_Oracle
>

works fine. I also export LD_LIBRARY_PATH which points to where 
libclntsh.so.11.1 resides. If I clear this environment
variable, import cx_Oracle fails with:

ImportError: libclntsh.so.11.1: cannot open shared object file: No such 
> file or directory
>

It looks like I have to tell my app what my path to libclntsh.so.11.1 is. I 
have added:

os.environ['LD_LIBRARY_PATH'] = '/oracle/product/11.1.0/db_1/lib'
>

to my app's wsgi.py file, but this does resolve my problem.

Can anyone assist with how to progress this?

Environment:
  O/S: Fedora14
  Apache: 2.2.17
  Python: 2.7
  mod_wsgi: 3.2
  cx_Oracle: 5.1
  Django: 1.4.1

Re: How to Set Up for Apace and Mod_wsgi

[Jon Blake]

Thanks, Mike, that fills in the gaps. 

Eddy Chan's notes discusses file apache/django.wsgi. This appears somewhat 
similar to wsgi.py in my project package - how do these two files relate to 
each other? And the entries in httpd.conf - they can go pretty well 
anywhere?

Eddy's notes refer to installing Apache2, along with libapache2-mod-wsgi. 
Is libapache2-mod-wsgi something different from the mod_wsgi 3.2 package I 
have already installed? 

TIA, Jon

How to Set Up for Apace and Mod_wsgi

[Jon Blake]

I've worked through parts 1 and 2 of the tutorial using the development 
server, and I have reviewed the doco on how to use Django with Apache and 
mod_wsgi. I want to trial a production environment on my Fedora 14 dev box, 
but the provided instructions assume some familiarity with configuring the 
Apache environment.

I have Apache/2.2.17 (Unix) installed on my development box and I have 
installed package mod_wsgi-3.2-2.fc14 (x86-64), but I'm not sure where to 
go from here. Can anyone point me to a a concrete example of file edits 
(eg, httpd.conf, wsgi.conf) I need to do to set up Apache and mod_wsgi to 
serve my application? I have a path to the application package, and I want 
URL http://localhost/polls/ to run it.

Re: Syncdb Error With Oracle Database - IntegrityError Exception

[Jon Blake]

I've just dropped and re-created my user account with required privileges, 
and all has gone as expected. Table auth_permission has 18 rows.

At the point where I'm prompted to create a superuser account, I made the 
mistake of resizing my terminal window, which resulted in exception 
EOFError being raised on the call to raw_input() in procedure 
create_superuser(). Sigh, and start again... This exception can be handled 
by calling raw_input() in a try block, and handling exception EOFError by 
(for example) shifting the cursor up one row by printing chr(27) +'[A' . 
HTH.

Again, many thanks. I'm on my way with Django - looking like a great 
framework!

Re: Syncdb Error With Oracle Database - IntegrityError Exception

[Jon Blake]

Thanks, Ian and Amyth, for your responses.

I encountered the CREATE TRIGGER privilege issue early in my trials with 
Django with the Oracle database back end - Django propagated an Oracle 
"insufficient privileges" exception. That was quickly sorted by granting 
the required privilege to my user account.

On looking at ticket #17015 you pointed me to, it looks like I might have 
stumbled over the same issue as in the reply to ikelly. My user did not 
have the CREATE TRIGGER privilege the first time I tried to run syncdb, but 
did have the CREATE_TABLE and CREATE_SEQUENCE privileges. After granting 
the missing privilege and running syncdb again, I then got the ORA-01400 
exception on table auth_permission.

I'm guessing that the first table that oracle back end base.py creates is 
auth_permission, and that the table and its primary key sequence were 
successfully created, because the user had the required privileges. Module 
base.py then terminated on attempting to create the trigger for the table. 
After granting CREATE TRIGGER and running syncdb again, base.py noted that 
table auth_permission exists, so nothing more needed to be done for that 
table. Module base.py then went on and created the remaining tables, 
sequences and triggers. Missing trigger auth_permission_tr -> no primary 
key raised from auth_permission_sq -> ORA-01400 on table auth_permission 
inserts.

Querying column timestamp of view user_objects for tables, sequences and 
triggers appears to confirm my understanding of what base.py does. I'll 
drop and recreate my user account, and try again. I'll advise how this 
goes. Does the Django doco have any specific documentation for the Oracle 
back end? If so, I missed it! I'm happy to provide specific doco for the 
Oracle back end if that would assist...

Once again, many thanks

Jon

Re: Instaling django

[Jon Blake]

What O/S?

I installed Django 1.4.1 today on my Linux F14 box today by:

1. Downloading Django-1.4.1.tar.gz from 
https://www.djangoproject.com/download/
2. As root:
# tar xzvf Django-1.4.1.tar.gz
# cd Django-1.4.1
# python setup.py install
# exit
3. Test it:
$ python
>>> import django
>>> print django.get_version()
1.4.1

HTH,

Syncdb Error With Oracle Database - IntegrityError Exception

[Jon Blake]

Just discovered Django and trying out the Django 1.4 tutorial with an 
Oracle backend database. In my database, I have created user django with 
privs create session, create table, create sequence, create trigger. The 
DATABASES dictionary in settings has been edited to set the default 
settings to the Oracle engine, and the database name, user and password 
specified.

When I run:

$ python manage.py syncdb

I see tables are created, but I also get a traceback ending with:

File "/usr/lib/python2.7/site-packages/django/db/backends/oracle/base.py", 
line 675, in execute
return self.cursor.execute(query, self._param_generator(params))
django.db.utils.IntegrityError: ORA-01400: cannot insert NULL into 
("DJANGO"."AUTH_PERMISSION"."ID")

I did not see a prompt to create a superuser account.

Oracle SQL*Developer shows that schema django contains 9 tables (including 
auth_permission), 16 indexes, 7 triggers and 8 sequences. Table 
django_content_type contains three rows, and the others are empty.

Can anyone advise on how to resolve the ORA-01400 error?

Run-time environment:
  O/S: Fedora 14
  Django: 1.4.1
  Python: 2.7
  DB: Oracle Database 11.1.0.6.0
  cx_Oracle client: 11.1.0.6.0
