Re: Best/Cleanest way to add fields to Class User in models.py?

[Kashif Ali]

I will suggest to create UserProfile model instead of customizing User
model. Add as many fields as you like in UserProfile model and use this new
model in your application wherever you are referencing User model.
You have todo some settings in your settings file in this regards.

Best/Cleanest way to add fields to Class User in models.py?

[Saqib Ali]

In my models.py, I use django.contrib.auth.models.User as a foreign key in 
many of the classes I created.

The User class obviously has a lot of important features that any website 
developer will need to track and manage users to the website.
However, I wish the class had three additional members -- all 
BooleanFields: myBoolA, myBoolB, myBoolC.

What is the safest/cleanest/easiest/best way to achieve this functionality? 
Where should I add those members? It seems unwise to modify the Django 
source package itself.

Django Calendar App Just Like Google Calendar

[Kashif Ali]

Hello Guys,

Is there any django app available that is a replica of google calendar?
I have checked django-scheduler, django-swingtime and couple of more but
the hardest part with these apps/projects is the limited documentation.
Can anybody please guide me what app can serve my purpose?

Thanks,

Hey guys, thanks for the help. 
(1 )I have confirmed mod-wsgi has been compiled against the correct version 
of python.
(2) I have also confirmed mod-wsgi is in the list of loaded modules.

My next question is what file do I place the WSGIScript directive in? I 
can't seem to find which file it goes in

Re: Project Structure - Lots of scattered custom views

[chad petzoldt]

 Sanjay, you were hitting things pretty close. I think that making sure 
slug names match up to real *static* locations is the key. I am hosting 
with Apache, and I thought about using some configurations to cheat a 
little bit, and get some of the static-files burden off of Django and let 
Apache resolve any requests that point to actual files on disk (with some 
security in mind).

What about a view that can determine if it should be pointing at a file on 
disk, and if so, do a custom Http_Response, and read the actually binary 
contents from disk by hand. Im just curious on this one; it could be an 
alternative means of file storage and recognition. I understand this may 
have some performance implications, but this is not going to break Django, 
correct? Is this bad Django etiquette?

Amirouche, a different way to describe what I am trying to achieve might be 
this: I would like to bypass the admin as much as possible when it comes to 
these "Articles". But when rendered, all of these articles do need at least 
a small HTML wrapper, and probably some kind of of global template that 
helps with navigation. If I could handle navigation without the admin, i 
would be very excited, but it does seem that I will need to use the admin 
for at least this purpose. The navigation would probably help render 
hierarchical  "menus" for use as templates within the Articles. I would 
like to keep this navigation as light as possible.

Thanks for the feedback.

Re: Custom jQuery in admin

[Jim Thaxton]

I'm not sure about your original problem but prefixing it with django will 
make use of Django's jquery namespace:

Django admin Javascript makes use of the jQuery  library.

Users will only see one document at a time so I'll follow Tim Chase's 
advise and assume its not an issue unless it becomes one in the future.

Thanks everyone for the replies.  I have to say I like this mailing list a 
lot.  It's a lot easier to ask questions here than on stack overflow.

Re: newbie needs to copy a record in admin to a new record

[Brad Pitcher]

I think what should work well for your use case is an admin action:

https://docs.djangoproject.com/en/1.4/ref/contrib/admin/actions/

You can write code for a copy action in admin.py. This will add a "copy"
item to the dropdown in the list view, so you can select any number of list
items and copy them.

Re: Form validation

[Kristofer]

More details on the form and why there is a field that depends on 6 pages: 

In steps 2-5, I am prompting the user for questions and choices about a 
particular service. 

On page 6 they are given the opportunity to select a date/time for the service. 
The validation will calculate how how much time is required based on steps 2-5 
and see if the time they pick fits in the calendar. If it doesn't, it will ask 
them to pick a different time. 

I'm still not sure where I can use it, because I can't call 
get_cleaned_data_for_step from the forms validation/clean field, and I'm not 
sure where else I can access the required form steps and also be able to raise 
a validation error.

If it doesn't need to be indexed (by which I also assume that you're 
not searching by its contents), that's actually a pretty small 
quantity of data to stash in a TEXT field.  So it should pose no 
problem.  The only other issue might be if you have cases where you 
bring back large quantities of these fields and try to display, in 
which case you're pulling N records time M 
average-bytes-per-text-record.  But usually users don't want to see 
that sort of volume of data.



I suppose the best way is to profile the app and see if the text
retrieval is a bottleneck but I thought someone on this list
would already have experience in this.


I'd code under the assumption that it's not an issue, and then 
profile if it becomes one.

If you are uploading to a folder and storing the path in db, then when
somebody moves the folder, then you need to update the all the
corresponding paths in the database.When somebody deletes the folder, then
everything will be gone.You need to take care of handling duplicate names
too.

Having said that.Serving from database is very slower  than serving the
documents from a folder.

Just my 2 cents.

Support for this would be an useful addition. Personally I have need
for at least now() and txid_current(), but preferably we want any
default clause (maybe even any per column SQL, so that you could do
CHECK too).

There are three problems for this feature:
  1. How to get the SQL into the CREATE TABLE clauses?
  2. How to return the values back after insert?
  3. If the way for no.1 is hand edited SQL, how to support this in
testing?

Above, no.2 seems the hardest problem. Some databases support
RETURNING, but not all.

Currently, you can do DB defaults by hand editing the sqlall output +
using post_save signal() and fetch the DB generated values into the
saved instance in the signal. But, you will need some way to solve no.
3 in this case. South might be a good option here. Personally I use a
custom testing system where I load the database schema from production
(with some data, too), apply migrations (that is, load custom SQL) and
then run tests.

Custom jQuery in admin

[Daniele Procida]

I had a custom widget, which broke after some other things were updated.

It was saying:

TypeError: 'undefined' is not a function (evaluating '$('#id_conta
cts_and_people-phonecontact-content_type-object_id-0-label').combo
box()')

Last night, I finally managed to fix it, after noticing that this script (which 
is injected into the HTML body as many times as required for each widget) began:

$(document).ready(function(){

while others I had seen began:

jQuery(document).ready(function($){

Changing it to the latter form made it work.

The only thing is, I don't really understand what was wrong, or how doing that 
fixed it.

I understand that a jQuery conflict of some kind meant that jQuery was unable 
to find the function "combobox()" and that probably this was because of the way 
the admin template was loading JavaScript files. 

But I don't understand what the changes actually mean, or what they do.

I also found that:

django.jQuery(document).ready(function($){ 

worked. Again, I don't know what that is doing.

If someone can explain what is going on in this example, that would be really 
helpful.

More generally, this sort of thing (jQuery conflicts) seems to be an almost 
constant issue for Django developers who create custom widgets. Is there a more 
general strategy for dealing with it?

Thanks,

Daniele

Function based generic views were deprecated in 1.3, TZ support
appeared in 1.4.

When a date based generic view is asked to filter against a
DateTimeField, it takes the specified day, and filters that field is
between datetime.combine(date, time.min) and datetime.combine(date,
time.max). datetime.combine only returns TZ aware datetimes if the
time supplied is TZ aware (time.min/time.max are not).

I suggest you update to use the class based generic views that arrived in 1.3:

Re: storing large amounts of text in the DB

text does not need to be indexed and I'm using MySQL.

That depends pretty much on the operations you perform over such field.
Fetch? Search? Concurrence updates?

Do you save such data anywhere (database, session...)? You might get from
this source and use as you need.

DateTimeField received a naive datetime (2013-01-10 00:00:00) while time zone support is active.

[Jeff Hsu]

Hi all,

   I kept getting DateTimeField received a naive datetime (2013-01-10 
00:00:00) while time zone support is active. but I can't figure out where 
it's receiving a naive datetime.  I have USE_TZ set to True in my setting 
file(stores timezone aware object in mysql?).  My url is as below:

urlpatterns = patterns('django.views.generic.date_based', #add the 
repetitive pattern here
url(r'^$', 'archive_index', entry_info_dict, 
name='coltrane_entry_archive_index'),
url(r'^(?P\d{4})/$','archive_year', entry_info_dict, 
name='coltrane_entry_archive_year'),
url(r'^(?P\d{4})/(?P\w{3})/$','archive_month', 
entry_info_dict, 
name='coltrane_entry_archive_month'),

url(r'^(?P\d{4})/(?P\w{3})/(?P\d{2})/$','archive_day', 
entry_info_dict, 
name='coltrane_entry_archive_day'),

url(r'^(?P\d{4})/(?P\w{3})/(?P\d{2})/(?P[-\w]+)/$',
'object_detail', entry_info_dict, name='coltrane_entry_detail'), 
#the forth arg will this patter a name
 #[-\w] will match letter, number or a hyphen
)

Every time I access a detail page from the archive index page, the error 
will pop out.  I'm using generic view to do my detail page, and I can 
figure out what's wrong.  Can anybody give me some direction?

Thank you,
Jeff

Don't be afraid to commit - a free Python/Django workshop (Cardiff, UK)

[Daniele Procida]

I have made a combined talk/workshop proposal for DjangoCon Europe in May (all 
proposals at ).

I want to run the workshop part a couple of times before taking it to Warsaw 
(assuming the proposal is accepted, but it's worth doing anyway). 

The workshop is free and open to anyone - so if you're interested and within 
reach, let me know. 

=
Don't be afraid to commit
=

A hands-on workshop for Python/Django developers who would like to contribute
more to the projects they use, but need more grounding in some of the tools
required.

What's in it for you


As well as helping to put you in a position to commit successfully to
collaborative projects, the workshop's emphasis on using virtualenv/pip and
git will help you manage your own work in a more streamlined and efficient
way.

The automated testing tutorial - the most substantial component of the workshop
- will help you develop your software faster, better and more easily.

What we'll cover


The workshop will take participants through the complete cycle of identifying
a simple issue in a Django or Python project, writing a patch with tests and
documentation, and submitting it.

The workshop will take you through the use of:

* virtualenv and pip
* git (and GitHub)
* running and writing tests for Python applications
* writing and building documentation using Sphinx
* submitting a pull request

A workbook and reference guide will be provided to support the workshop.

What you need to know
=

The workshop is open to anyone, but places will be limited.

Date: a weekday morning or afternoon in February or March 2012
Venue: Cardiff University
Attendance fee: none

Let me know if you'd like to attend!

Daniele
