Slow performance with Django when connected to Oracle

[dw314159]

Django gurus:

Hello, I am experiencing very slow performance with Django when
connected to an Oracle database. The exact same Django application
runs far faster with PostgreSQL and SQLite, with the same source data
loaded into each database. Looking at the information embedded in
“connection.queries” after making an Oracle query through Django, it
appears that the queries themselves run very quickly (runtimes are
comparable to those measured with PostgreSQL and SQLite), but the
whole turnaround time for a query in Oracle far exceeds the reported
query time.

I’ve tried the built-in Oracle backend engine and django-oraclepool
0.7; neither improve performance. (With django-oraclepool, I also gave
sufficient time for the connections to pool before taking
measurements). Using cx_Oracle outside of Django on the same
workstation to connect to the same Oracle database, the query
turnaround time is very quick.

Is this problem connected to the fact that Django is reported to drop
the database connection between queries, and therefore must reconnect
to Oracle every time a query is executed? Or is there a Django
configuration option that must be specified to make the best use of
Oracle?

We are using Python 2.7, Django 1.2.1, Oracle 11, and Apache HTTP
Server 2.2.17.

Any help would be greatly appreciated.  Thanks!

DW

My apologies to the list.

I just noticed the commas at the end of the lines in the views.py

Once I got rid of those, all was much better.

For the record, I *am* responsible for Django's documentation, and
most of the answers provided by Aryeh are correct. A couple of minor

I would also add: Easily writable and readable by humans without
extensive tool support. It's a very lightweight markup format, and the
source is almost as readable as the final product.

Django doesn't have autogenerated API docs -- mostly (IMHO) because
this is a feature of Python itself -- anything that could be
automatically generated could also be determined using the interactive
prompt.

Correct, although:

 * We have a couple of committers whose sole responsibility is to
maintain the documentation

 * Several of our core committers, including our two BDFLs have formal
training in the arts; Adrian is a Journalism major, and Jacob is an
American Literature major. We also have a Philosophy major and three
doctorates in our team. Overall, the "developers" are a literate
bunch, not just a bunch of hackers forced to write some docs.

Correct -- as for the reasoning behind this: our experience has been
that wikis become a wasteland. Good documentation, like good design,
isn't something that can be arrived at by committee, or by consensus
-- it requires strong decision making and editorial 'taste' to build a
coherent and useful body of documentation.

However, we are exploring some ways to make it easier for people to
contribute suggestions and modifications to the documentation.

Yours,
Russ Magee %-)

cleaned_data not behaving how I expect it to. (newbie confusion)

[Ben Dembroski]

Hi all.

Another silly question.  I'm hoping someone here can explain something
about the way form validation and processing is working in the
following example of User Registration:

>From forms.py

class RegistrationForm(forms.Form):
username = forms.CharField(label=u'Username', max_length=30)
email = forms.EmailField(label=u'Email')
password1 = forms.CharField(label=u'Password',
widget=forms.PasswordInput())
password2 = forms.CharField(label=u'Repeat Password',
widget=forms.PasswordInput())
fname = forms.CharField(label=u'First Name', max_length=30)
lname = forms.CharField(label=u'Last Name', max_length=30)

def clean_password2(self):
if 'password1' in self.cleaned_data:
password1 = self.cleaned_data['password1']
password2 = self.cleaned_data['password2']
if password1 == password2:
return password2
else:
raise forms.ValidationError('Passwords do not match.')

def clean_username(self):
username = self.cleaned_data['username']
if not re.search(r'^\w+$', username):
raise forms.ValidationError('Username can only contain '
'alphanumeric characters and
the underscore')

try:
User.objects.get(username=username)
except User.DoesNotExist:
return username
raise forms.ValidationError('Username is already taken.')

The relevant bit of views.py:

form = RegistrationForm(request.POST)
if form.is_valid():
user = User.objects.create_user(
username=form.cleaned_data['username'],
password=form.cleaned_data['password1'],
email=form.cleaned_data['email'],
)
user.first_name=form.cleaned_data['fname'],
user.last_name=form.cleaned_data['lname'],
user.save()
return HttpResponseRedirect('/select')

When I test use the form, and enter a username, password, email, first
and last name, it creates a user.  However, the saved values for the
first and last name aren't what I expected:

>From manage.py shell:

>>> User.objects.all()
[, , , ]
>>> peep = User.objects.get(username='nexttest')
>>> peep.first_name
u"(u'next',)"
>>> peep.last_name
u"(u'test',)"
>>> peep.username
u'nexttest'
>>> peep.email
u'nextt...@doo.com'
>>>

As you can see, the values for the first_name and last_name are
unicode strings that represent a tuple?  The other values seem to be
just fine.

Any explanation on why this is happening?  Or pointers on where to
look? I've re-read the documentation on forms, the usual googling,
etc.

This is using version 1.2

Many thanks!
Ben

I think I can answer my own question: as_table() is a method of
ModelForm objects, not Model objects.  So I tried pointing DetailView at
WSMRTaskForm, but now I get the exception:

type object 'WSMRTaskForm' has no attribute '_default_manager'


Frustrating!  Any suggestions?  It doesn't seem unreasonable to want the
DetailView to be able to render the "default" tabular view of the Model
created by:

class WSMRTaskForm(ModelForm):
class Meta:
model = WSMRTask

Thanks,

Ian

This sounds good.  Form Preview could be useful, but right now I just want

{{ object.as_table }} returns nothing, whereas, {{ object.name }} etc. works

Re: incrementing counter of an cached data

[Michel Thadeu Sabchuk]

You can hit the counter through ajax and still keep the cache of the
entire page. This is useful if you have a cache through nginx +
memcached.

Testing in a project with multiple databases

[Stathis]

Hello everyone,

I have set up a project with multiple database connections (default
and legacy). I use models for the default database, but the legacy db
is not managed by models. I issue raw sql to query the legacy
database. Django-nose and south are  used.

I am facing multiple problems:

- When I run the tests two test databases are created (which is fine).
Nevertheless, django system tables (auth etc) are created in the test
legacy database (which is something I want to avoid). What is more, a
south script which uses the models is also run against the test legacy
database causing a failure.

- I am looking for a way to create the structure of the test legacy
database before testing. I want to do this by raw sql as the legacy
databased is not managed by models. Is there any way to do that?

Thank you.

RE: Re: incrementing counter of an cached data

[Henrik Genssen]

are you using middleware or a decorator for caching your view?
if you are using a decorator like @cache_page from 
django.views.decorators.cache you can add simply a second decorator befor the 
caching one, where you count your hits...
if you are using a middleware, you have to write your own cache middleware 
(copy the existing and add you counter)

Re: Database synchronization with sometimes-connected mobile client

[Eric Chamberlain]

We had to work through similar issues with our iPhone and iPad applications.

We wanted to decouple the server development from the iOS applications and 
decided to not try and mirror the device and server database schemas, we pass 
objects back and forth and let each implementation store the underlying object 
however it needs to (CoreData or SQL).  

Our object tracking is loosely based on Active Directory's multi-master 
replication model.  We track objects by UUID and last modified timestamp.  The 
device(s) can then pull/push all the moves/adds/changes since the last sync.

I don't believe that django does, but sphinx is capable of this.
See the matplotlib documentation, for example.  I believe the api docs
are auto-generated.

Seems to me that documentation is treated same as code.  Those who

Read-only forms/fields are a popular topic, but not supported in
django.  To display data, simply put the data object (i.e. a model
instance) itself in a template context and render it.

Perhaps this would be of use to you:

Not really -- it explains why adding it makes things work, but it
doesn't explain why I *have* to include it.  "syncdb" is smart enough to
figure out that DerivedModel(BaseModel) has django.db.models.Model
*somewhere* in its super-class ancestry, so I don't see why it can't
also be smart enough to then figure out that "BaseModel" needs to be
included for ORM automatically.

read-only Form.as_* views

[Ian Stokes-Rees]

I love the fact that I can quickly and easily get a "view" of my objects in

where fields are not editable?  I want to be able to display the "forms" 
once they are completed but with the fields displayed just as table entries 
or textareas which can't be edited.  In other words, no  or  
tags.

It's definitely #2. Because when the model isn't abstract, the fields
in the base model aren't created for the subclass -- the subclass has
a foreign key to an instance of the base model.
That last bit should explain why you need to have the base app in
installed apps.

No, it isn't abstract.  It has a particular content model and methods
associated with it.  When you say the ORM will "want" to create it in
the DB, do you mean:

1. It should figure this out on its own and create the base model table; or
2. The ORM needs this so it must be listed in INSTALLED_APPS to have the
relevant table created in the DB.

Right now it looks like the situation is 2., but I'm wondering if there
is a good reason why it can't be 1.

Questions about documentation management

[anastasia]

Hello,

My name is Anastasia Cheetham. I'm a developer with and the
documentation lead for the Fluid Project (http://fluidproject.org).
We're beginning the process of restructuring and redesigning the
documentation for our Infusion framework. Part of that process will
include migrating to a new platform for the creation and distribution
of documentation, and we're interested in learning about the
experiences of other open source projects, including Django. I'm
hoping that someone might have time to share some thoughts about how
you team manages documentation. For example:

- What platform does Django use for its documentation? (e.g. a wiki?
DocBook?)

- What did you like about your platform? What are its weaknesses?

- How easy or hard it is to customize the look and feel of the
interface with your platform? i.e. style, layout, navigation, etc.

- Do you use any form of auto-generated API documentation? If so, how
to you manage integration with more narrative text such as tutorials,
examples, etc?

- How do you manage versioning of your documentation (i.e.
documentation specific to a particular version of Processing)?

- Are developers involved in writing the documentation, or is that
left to technical writers?

- Do you support community input/editing of documentation? Why or why
not?


I thank you very much for your time, and for any thoughts you can
share.

Getting value from session in ModelForm

I am new to Django and building a school system but am an experienced

I have the following class where on teacher add/edit form, I am trying
to filter values in class drop down based on school.  The value of
school_id is saved in session but as you can see below pulling value
from session fails in ModelForm, can someone please guide me on how to
get the value from session here ?


class TeacherForm(ModelForm):
def __init__(self, *args, **kwargs):
super(TeacherForm, self).__init__(*args, **kwargs)

xclass = self.fields['xclass'].widget

choices = []

#school_id = request.session['school_id'] # since this
fails, I have hard coded the value 2 in line below for now
school_id = 2
xclasses = Class.objects.filter(school=school_id)
for c in xclasses:
choices.append((c.id,c.name))
xclass.choices = choices

Including apps for inherited models in INSTALLED_APPS

[Ian Stokes-Rees]

Does it make sense that inherited models also need their apps included in 
INSTALLED_APPS?  Right now if I have:

base/models.py:

class MyBaseModel(django.db.models.Model):
   stuff

and then elsewhere:

derived/models.py:

class MyDerivedModel(base.MyBaseModel):
   stuff

I need to include both "derived" and "base" in my INSTALLED_APPS list in 
settings.py, otherwise the table for the MyBaseModel content is never 
created.  It seems to me that "syncdb" should be able to "see" that 
MyDerivedModel has MyBaseModel as a super class in the chain to 
django.db.models.Model and consequently create the necessary tables for 
MyBaseModel.

Or have I just misunderstood why it was necessary for me to include "base" 
in order to get the tables created properly by "manage.py syncdb"?

TIA, Ian Stokes-Rees

Re: 'module' object has no attribute 'Form'

[Shawn Milochik]

The problem is your "star" import from localflavor, which contains a
'forms' module.

Just import what you need from localflavor.

Re: Is there any way to get the ip address of the user in the post_save signal?

[Cal Leeming [Simplicity Media Ltd]]

Hey,

In previous projects, we have addresses this issue by making the HTTP
Request object available globally.  I have placed the code you need to do
this here: http://djangosnippets.org/snippets/2352/

Please note, this method is
slightly frowned upon in the community, but sometimes rules have to be bent
a little :)

Hope this helps.

Error when editing Inline OneToOneField

[Pascal Germroth]

Hi,

using SVN revision 15440 I get some weird behaviour:


Part of my model looks like this:

-
from django.contrib.gis.db import models

class Address(models.Model):
  uuid = UuidField(primary_key=True)
  readable = models.CharField(max_length=200)
  geo = models.GeometryField()

  def save(self, *args, **kwargs):
self.readable, self.geo = geocode(self.readable)
super(Address, self).save(*args, **kwargs)

class Corporation(models.Model):
  uuid = UuidField(primary_key=True)
  name = models.CharField(max_length=200)

class Branch(models.Model):
  uuid = UuidField(primary_key=True)
  address = models.OneToOneField(Address)
  corporation = models.ForeignKey(Corporation)
-

In the admin interface I use

-
class AddressAdmin(admin.ModelAdmin):
  readonly_fields = ('geo',)
admin.site.register(Address, AddressAdmin)

class BranchInline(admin.StackedInline):
  model = Branch
  fields = ('address',)

class CorporationAdmin(admin.ModelAdmin):
  inlines = [BranchInline]
  fields = ('name',)

admin.site.register(Corporation, CorporationAdmin)


Now for the weird part:

Add a corporation via admin interface, click save, works as expected.
Open the corporation again, in the inlined branch, add a new address,
click save, works as expected.

Then: open that corporation a third time, no matter what you do (delete
a branch, add another, change anything) clicking save returns this error:

MultiValueDictKeyError at
/admin/base/corporation/2b97beda-6893-426c-8229-ddf001394d36/
"Key 'branches-0-uuid' not found in "


I'm worried about the mention of branches.uuid -- this shows up
nowherein the generated form (only a select 'branches-0-address' with
the uuids of available addresses).

Playing around with fk_name on the inline admin brought me nothing but
error messages…

This only seems to concern the InlineModelAdmin. When I use seperate
ModelAdmin-s, everything works.


Where should I look for the bug? Might it be my custom UUID-field? (but
it seems to work…)

'module' object has no attribute 'Form'

[shireknight]

I created a form in forms.py with this code:

===
from django import forms
from django.forms import widgets
from django.contrib.localflavor.us import *
import datetime

class InquiryForm(forms.Form):
===

Exception Value:

'module' object has no attribute 'Form'

Exception Location:   /path/to/my/project/inquiry/forms.py in
, line 6

I tried importing in the shell and I got this output. So it seems to
import the file:

===
In [1]: from django import forms
In [2]: forms.Form
Out[2]: 
===

I'm stumped.

I think this option is the one that should work and isn't in 1.2.4. You have the
following two choices:

 - Go back to 1.2.3
 - or use a checkout of the 1.2.X maintenance branch at revision
[1]15405 or newer.
   The fix for this temporal regression in 1.2.4 will be included in a
future 1.2.5

I don't have an answer but have you looked at the localization file
for nl to see if something has changed between the two versions?  If
so you could modify that to fix the problem short term but of course
that would get overwritten with the next update.  That might be OK if
it is a bug in the localization and it's fixed in the update you
download.

I'm not up on all the localization stuff but perhaps you can modify
the localization file and then put it outside of the normal django
directory and have your install use that file.  Take a look at <
http://docs.djangoproject.com/en/1.2/topics/i18n/ >.

problem with date and decimal changes between 1.1.1 and 1.2.4

[Jop]

Hallo,

I am upgrading a Django project from 1.1.1 to 1.2.4. Unfortunately I'm
running into some trouble concerning date and decimal formatting in
1.2.4. What I'm looking for is to match the original situation as we
need the dates to be the same for xml feeds etc and the point for
javascript. I know I can use a template filter on all the dates in the
templates, but this is a lot of work and has the risk of missing
something somewhere. What I'm looking for is a confirguration setting
which fixes this problem.

Original situation (1.1.1)
- Dates: 21-12-2010
- Decimals are point separated.

New situation (1.2.4 with: I10N=False and LANGUAGE_CODE = 'nl'):
- Dates: maart 1, 2012
- Decimals are point separated

Other new situation (1.2.4 with: I10N=True and LANGUAGE_CODE = 'nl'):
- Dates: 1 maart 2012
- Decimals are comma separated

When I try on the pythonprompt the locale.getdefaultlocale() returns
('en_US', 'UTF8').

Thanx for your help / time!

Re: How can I show a list of values in a text input field?

[Nate Reed]

Bill, thanks for your reply.  I considered rendering the form
manually, and that would be a fine solution.  I ended up creating a
custom widget (MultiValueTextWidget) that joins the input values.  I
don't know if this is the best solution, but it solves the problem of
rendering the values as a single input field:

class MultiValueTextWidget(TextInput):
def _get_value(self, value):
return " ".join(value)

def _format_value(self, value):
if self.is_localized:
return formats.localize_input(self._get_value(value))
return self._get_value(value)

Overriding __str__ (or was it __unicode__?  I don't have the code in
front of me) results in user-friendly values being rendered instead of
object id's.

My form has a clean method which splits the values and validates them,
and the view handles splitting the input and setting the many-to-many
relation.

I realize this is an unconventional way to render many-to-many
relations in a form, but in this particular case that's how I wanted
to allow the user to see and edit the values.

Thanks,
Nate

I think the problem there is that the HttpRequest object isn't
available by default to the post_save signal.

Some of the ways you might get access to the ip...

Add an ip field to your model and then when processing the POST in
your view attach the ip to your instance then save.  I used this
method myself for a discussion model that tracks the ip of the poster.

If you don't want to store the ip you might try ( untested )
attaching the ip as an attribute to the model instance similar to
above and see if the attribute survives to the post_save signal.

You could also try something similar to the above with the
instance save method but then you wouldn't be handling it at
post_save.

You could also create your own signal system for use when
processing the POST in your view that handles your ip address needs.

It all depends on what you want to do with the ip address.  If you let
us know more about what of your situation we might be able to give
your more ideas.

You have a related problem in terms of what you want to have happen
when the form is submitted.  The string that you get needs to be
converted to objects (or their id's) before you can save them to the
DB, and a representation of the id probably isn't what you're expecting
to show in the field.

CharField is mostly suitable for submitting a character string, typically
stored in the DB as a character string.  Relation fields are more amenable
to a (multi-)select field or radio buttons (check boxes for multiple valued
fields).

You could create a custom form field, if this scheme is truly what you
wish.

You can also render the desired input within your form by hand, instead
of expecting the from object's as_p(), etc. to render it for you.  You will
then also need to check the submitted value in the POST or GET data,
since the form object doesn't know about it.  The template language is
strong enough to render what you want if you pass the related object
manager to the template, but it is a bit hairy for a template, so I'd
suggest having your view function calculate the desire value string
for the input, and pass that instead.  When you parse the posted
value, you will still need to look up the objects somehow from the
submitted value.

[Stodge]

I need to know who changed a particular model through the admin site so I

Re: How to define each model in its own file

[Alendit]

Hi,

as far as i know you also have to define the app_label as Meta
parameter like this

class Meta:
app_label = "your_app_name"

Regards,

Alendit.

cannot login to admin site using admin credentials

[xpanta]

Hi,

it seems that my problem is a bit complicated. I have tried much but
to no avail. So, please help me!

Some time ago I migrated to postgresql from mysql. I don't know if I
did something wrong. Anyway, my webapp works "almost" flawlessly.

Since then I never needed to login using admin rights (either using
the admin panel or my web site). Some weeks ago I tried and I noticed
that I can't login (to both admin site and web page) using admin
credentials.

I have tried dozens of various tricks but I still can't login.

I tried adding user.set_password()  to my views.py in order to replace
admin password with a new simpler one ('123') but nothing. I even
registered a new user from my web page and changed its fields directly
in the DB (is_staff, is_active, is_superuser) to 'True'. This let me
login to the admin site but gave me no permission to change anything.
I even tried to create various admin users with the help of django
shell but none of them gives me a login. Interestingly whenever I do
something to change admin password, I always see a different hashed
password value in my DB. This means that all my approaches succeed in
changing the admin password. However I can't login.

Normal users work fine. Problem appears only when the user is an
administrator.

Any help would be greatly appreciated.

Re: How to define each model in its own file

It is also possible to import you models from *models/** from within *
models.py* file.

Nope, because Django's templating system doesn't know anything about
the template's structure/syntax. The templating system can be used for
more than just HTML (e.g. JSON, XML, CSV etc.).

What's wrong with using the {{ }} templating syntax? The alternative
you're suggesting makes things very confusing - the template will be
getting values from two different places, and what happens if there is
more than one form in the template with the same field name?
