That is the only available solution currently, apart of raw SQL which
is an often overlooked alternative.

You could do that update in an overridden .save method. Make it take a
kwarg 'update_fields=[],' or 'only_myfield=False'. Then, you can just
use model.save(only_myfield=True). The save method could then handle
all the necessary dirty details.

BTW even if there is a filter operation, there will be just only one
query. Actually, your method will be more effective than normal save,
as without force_update the current implementation of .save() needs to
first do a select, then update. You can see the queries made by using
django-debug-toolbar, or just by running this in the shell:
from django.db import connection
from django.conf import settings
settings.DEBUG = True
self.__class__.objects.filter(id=self.id).update(myfield='new awesome
value')
print connection.queries

Modify only one field

[Ashe]

Hello,

Is there a better solution to modify only the specified field on a
table than :
self.__class__.objects.filter(id=self.id).update(myfield='new awesome
value')
?
I have been looking for a cleaner solution for a long time without
success, while waiting for that ( https://code.djangoproject.com/ticket/4102
).

If it is the best solution, is there any drawback with that solution ?
I suppose there is a read on the database because of the
objects.filter(). And we lose the possibility to use save() and
clean() before update, which I usually enjoy to override.

Checklist for appreciating a project from 1.2.7 to 1.4a1

[Alec Taylor]

Good afternoon,

I'm bringing the "social-commerce" project up to the latest trunk of
Pinax and Django.

Is there a checklist of things I'll need to update?

I've begun updating it, i.e. adding the new database dictionary:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'OPTIONS': {
'read_default_file': '/path/to/my.cnf',
},
}
}

But it keeps giving me error after error once I've done that, so
instead of tackling issues one at a time, I thought their might be a
guide of some sort?

Thanks for all suggestions,

Alec Taylor

djangobench results (1.4 vs 1.3)

[akaariai]

I just completed some runs comparing performance of 1.4 vs 1.3 using
Djangobench. There doesn't seem to be any repeatable significant
regressions or gains except for these two tests:

Running 'url_resolve' benchmark ...
Min: 0.00 -> 0.00: incomparable (one result was zero)
Avg: 0.92 -> 0.000142: 1.5424x slower
Significant (t=-8.211439)
Stddev: 0.9 -> 0.00010: 1.0696x larger (N = 500)

Running 'url_reverse' benchmark ...
Min: 0.00 -> 0.00: incomparable (one result was zero)
Avg: 0.000100 -> 0.000168: 1.6761x slower
Significant (t=-8.269947)
Stddev: 0.00012 -> 0.00014: 1.1812x larger (N = 500)

I don't know if 50% slowdown in these tests are critical. Maybe worth
checking where the difference comes from.

I also compared 1.4 vs 1.3 when USE_TZ was set to on. No regressions
there.

So, nothing really interesting found, which I guess is good news.

BTW are there anybody who is running these kind of tests regularly? I
mean is there any point of reporting these kind of finds, or are they
already known?

When it suits your needs. Sorry for the stupid answer :)

You have basically three ways to do form processing. ModelForms is the
easiest, everything is easy and magical. The only problem is that
there is happening a lot behind the scenes, and it can be hard to get
full control of things when using ModelForms. Next choice is regular
Forms. There isn't much magic, they take some data in, validate it and
convert the data into Python values. However, even this can sometimes
limit your options. So, the last way is to not use Django's forms at
all. Just use request.GET and request.POST directly. This can come
handy if you really need it. But you almost never need to go this
route.

So, if you find out that ModelForms are hindering your development
instead of accelerating it, try without ModelForms. Otherwise, there
really isn't any rules when to use what kind of form processing.

Re: Entering Text into a Database

[ds39]

Thanks to everyone who took the time to respond. I've been looking at
the godjango website, and its been very helpful with figuring out
forms. I was able to modify some of the tutorial examples on the site,
adding form.save(), to successfully enter text into the database. So,
I think I've found my answer. The only other thing I was curious about
was when and when not to use something like ModelForms with user-
entered data. For instance, are there times when text responses
associated with different users should be handled some other way ?

Thanks again

like i said, i've used treebeard w/o problems so i don't think it's bad.
my question/interest is mostly because i've noticed that most projects use mptt.

Yes you need to put register = template.Library() in your module. See

Re: Help Me With omab/django-socialauth

[Matías Aguirre]

Django-social-auth (note the hyphen ;)) uses LOGIN_URL as the URL to redirect
in case of errors if LOGIN_ERROR_URL is not defined, you might be getting an
error and being redirected to your LOGIN_URL and as your value is
/login/twitter/ you are restarting the process again.

Another possible flaw is your SOCIAL_AUTH_ENABLED_BACKENDS = ('twitter')
you should add a comma after the value or it won't be a valid tuple, like this:

SOCIAL_AUTH_ENABLED_BACKENDS = ('twitter',)

LOGIN_URL? Because mine is '/login/twitter/' thats where the problem
is.

But here I have views as :

and for this I have template as :

   {% if client %}
{% for clients in client %}
{% for amounts in amount %}

 {% if clients.job_no == amounts.job_no %}

 {% if clients.name_and_address == clients.name_and_address %}

{{ clients.receipt_no }}
 {{ clients.date }}
{{amounts.total}}
{{amounts.net_total}}
{% endif  %}

{% endif  %}

{% endfor %}

{% endif %}


When all this is applied, it creates a view out of 2 tables i.e Amount
and ClientJob without using foreign key. Now I want to have sum of the
total and net_total fields for the views generated.

Your question is a little bit confusing. Django's URLconfs don't really 
care about applications, except in as much as can choose to group a set of 
urls into an application's own urls.py if you want to. There's nothing that 
forces you to route all requests to application `foo` to /foo/whatever: if 
you want `foo` to be responsible for answering requests at `/`, then just 
configure it that way:

(r'^$', 'foo.views.main')

or include the whole sub urls.py at the root url:

(r'^', include('foo.urls'))

I don't get what "url in address bar should change". So, the answer
might not be to your question...

Basically, you want to use the url template tag, from the
documentation:
{% url path.to.some_view v1 v2 %}

In your case, this would be something like:
Logout
That is, you are fetching the url for polls.views.logout_view without
any arguments. Detail view for poll no 1 would be something like this:
View poll No. 1

This is very basic introduction to Django's url resolving. And the
given code might actually not work correctly, haven't tested it. It
should contain the idea, though. I suggest you use some time learning
more about the url resolving system, it is time well spent.

You do not need (or want) to have multiple URLs defined for the
logout_view. That is, remove the logout_view mapping with poll_id
argument.

Re: Need help regarding url patterns

[ankitrocks]

Hi.
Thanks for replying.

The reason  I used login/logout multiple times in the urls.py because
i was unable to redirect from polls/03/logout to polls/login. When I
am using href="../logout" , it works but sometimes when I am in
level-2 in doesnt work.
Please ignore the parameters of poll id in login/logout. Its just that
I was trying something and forgot to remove the code.

Now I went through reverse thing. I didnt get an idea about how do I
redirect from a logout link in any page to polls/logout and also the
url in the address bar should change. Please help me out.

If you want your django app to be the root of your django project, you
just have to fix your root urls.py. FWW, here's the relevant part of
my current project's root url.py:

urlpatterns = patterns(
'',
url(r'^$', main_views.home, name="home"),
url(r'^blookshop/', include('blookshop.urls')),
url(r'^admin/', include(admin.site.urls)),
   )

googling +django +redirect +view, I get the answer at the very top of
the list.

Re: Help Me With omab/django-socialauth

[Kevin]

Did you take a look at the example project?

https://github.com/omab/django-social-auth/tree/master/example

Compare it with your own project, or even use this example project as
a base for your own project.

If all your urls.py contains is "url(r'',
include('social_auth.urls')), " and no other definitions, this could
be why it redirecting, as it cannot find the URL it's suppose to land
on.  Check the output in the Windows command window and see what URLs
are being requested and see if there's anything odd.

how do I model an auto-populate name from admin authorised users list

[Krondaj]

Hi,

I have written a model for a web form (of sorts) I'm making that
people can fill in from the admin site.  I have set permissions from
the admin end so they can only write or change new posts of the form
(see http://dpaste.org/BZ5Nm/). it's still work in progress  but I
have two problems.

First instead of using a CharField to take their name, i'd like it to
auto populate, there full name and email address as they will be
logged in and authenticated at the admin login site.


Secondly instead of having a set of name choices for the approver i'd
like to make a group in the admin called approver, and have it let you
select from a list (so if we have a new approver i can just add them
to the group).  I know how to make the group, i just don't know how to
get the model to display these in the admin site as a drop-down list.

I'd also like the database to link the first form and the second
form... and make it so only the person who has been requested to do
the work can fill in the required fields.

Can anyone give me some clues/ell me how to do this My coding
skillz are somewhat lacking!!??!! so i'd really appreciate any help!

Actually, there doesn't need to be an insert between the calls if you
don't use .order_by(). Technically, without an ORDER BY the database
is free to return the records in any order it wishes, even if there
are no inserts in between.

I think you really should fetch all the needed objects in one go. That
is the correct way to do what you need. And in addition it is more
efficient.
