Re: Article Viewer / Better way to do this? / Suggestions Please

[Barry Morrison]

I built the model as I imagined how it should be. Looks like I can rework 
it to not need the pages model. Thanks for that! 

The .url is also fantastic! 

Much appreciated! 

Thanks.

Re: cannot access admin

[Nikolas Stevenson-Molnar]

One thing you might consider is using a prefix for article URLs so that 
you can more easily differentiate them from other URLs. For example:
r'^articles/(\S+)/(\S+)' . Then, rather than a URL like
/source-code/c++, you'd have /articles/source-code/c++.

Re: cannot access admin

[Scott Somers]

here we go I actually had a typo that slipped in, everything is working 
perfectly now thanks again to everyone.

urlpatterns = patterns('',
(r'^media/(?P.*)$', 'django.views.static.serve', 
{'document_root': settings.MEDIA_ROOT }),
)

urlpatterns += patterns('',
url(r'^$', 'tacobakedotnet.dotnet_forms.views.home'),   
 
url(r'^admin/', include(admin.site.urls)),  <--- had a $ here
url(r'^(\S+)/(\S+)', 'tacobakedotnet.dotnet_forms.views.home'),

Re: cannot access admin

[Scott Somers]

Yes, and this is a little embarrassing I was missing a line from the 
debugging output.

/home/tacobake/Source Code/Python 
(Komodo)/tacobakedotnet/../tacobakedotnet/dotnet_forms/views.py in home

   1. 
   
   article = Article.objects.get(menu__menu_title = menu, 
article_title__startswith=item)  
   
   

So that is where the word "Article" comes from in the earlier error message.

Now having said that I believe it is the permissiveness of the \S+ \S+ 
which may very well be what the problem is, I am going to change it but I 
need to learn a bit more first.  Basically I need the best way to pass a 
pair of options to the view function, which also just happen to be the URL, 
I was reading about it in the basic documentation for urls.  I do 
appreciate everyone's help.

Like if I set it to:

url(r'^source-code/(\S+)', ...) that is not dynamic enough for the view 
function, "Source Code" or source-code being the menu_title.

Re: Article Viewer / Better way to do this? / Suggestions Please

[Nikolas Stevenson-Molnar]

Yes, pagination should get you what you want here. Using Django's
built-in pagination, you can drop your Page model completely (unless you
have a compelling reason to persist the page structure rather than
letting Django determine it for you on the fly). One additional note,
your Page.thumbnail_ method looks like something that would be better
suited in the template. Also, ImageField (and FileField) gives you a
handy "url" attribute. E.g: instead of constructing the path to the
image using thumbnail.name, you can do this (in a template): {{
article.thumbnail.url }}

Article Viewer / Better way to do this? / Suggestions Please

[Barry Morrison]

I have a bunch of press articles, these articles are basically
thumbnails that open up to the pages of the articles.

Here's what I've got so far.

https://gist.github.com/0951804f4592c970b18b

My thoughts are to use something like Django's pagination [1]
https://docs.djangoproject.com/en/1.4/topics/pagination/

Is there a better way to do this???

Thanks!

Re: Admin actions -- short_description as doc string?

No - because a docstring and a short description serve different
purposes. A docstring documents the purpose of the method. The
short_description is a label that can be used for display purposes --
a 'human readable' version of the method name.

For example:

def reset(…):
"Reset all the things to their original values"
….
reset.short_description = "Reset all the things"

Although you may often be able to compose a docstring that could also
serve as a short_description, it won't always be possible; hence, a
distinction is made so you can be explicit about exactly what you
want.

Yes. \S+/\S+ will match /. Since /admin doesn't
contain a slash (other than the leading slash, which isn't considered),
it works fine. But /admin/whatever will get directed to your
tacobakedotnet.dotnet_forms.views.home view because it matches the URL

Re: migration via south for inheritance change -> please help

[Tomas Neme]

By the way, if you do that, and I'm not crazy, you won't need to do any
migration with south, since the Foo and Bar tables would both have all of
base's columns (because Base is abstract).

If Base can't be abstract (if you want Base instances that are neither Foo
nor Bar), then you'll have to do this:

First, create the Base class, without changing Foo or Bar. Create a south
migration for this

Second, create a south Data Migration, copy all the data over on that
migration from Foo and Bar to Base instances

Third, modify Foo and Bar, and create migrations for this

RE: migration via south for inheritance change -> please help

[Demian Brecht]

I'm not a South expert, but I'd assume you'd do this via south data
migrations
(http://south.readthedocs.org/en/latest/tutorial/part3.html#data-migrations)
.

You'd create:
- One (auto) migration script to create the Base table and new columns in
Foo and Bar
- A data migration script to migrate the current data set from Foo and Bar
into Base and fill in the OneToOneField keys accordingly
- A final (auto) migration script to remove the transferred fields from Foo
and Bar

I'd like to know this too - but I think the real answer is "get better at
python" - you are essentially (from what I can tell) in a django shell when
south pops the "not blank, not null but no data" error - try pulling in some
details from fixtures?

Re: mysqldb help! Can't connect to MySQL server error...

[Matthew Piatkowski]

mdsmoke, do yourself a favor. You have exposed your password and the user 
name of your db; change your password.  Also, best practices for using 
databases, is create an administrative login insead of using 'root'.  Its 
much easier for a nasty malicious person or organisation to guess (root) 
than it is for them to guess a random 'user name' 

As far as your topic issue, I'm not sure.  I have the same issue.  I'll let 
you know when I figure this out too.

Re: migration via south for inheritance change -> please help

[Tomas Neme]

You'll have to migrate your data manually in your migration, yes.

Besides that, if you don't want actual Base instances, then this is an
abstract class, and you should do this:

class Base(models.Model):
eggs
plants
class Meta:
abstract=True

class Foo(Base):
carpet=

class Bar(Base):
car=

Re: custom500 page does not show up ?

[Nikhil Verma]

Hi Melvyn,


The interesting thing is 404.html is working but not 500.html.
In settings paths are dynamically set. Also i am receiving the error
messages on my email as i am the admin.
Let say there is some syntax error so in the email it will give me
information about that but without displaying 500 page.

I am  amazed then why 404 is working.

Re: problem with django model method save()

[Tomas Neme]

I don't see why wouldn't your model's .save() work, maybe we'd need to see
the model code, but I know you probably want to read this:

https://docs.djangoproject.com/en/dev/topics/forms/modelforms/

once you've implemented a ModelForm, you'd pretty much would just do

form = RoomForm(request.POST)
if form.is_valid():
  form.save()

It looks like you have the project name in the view, which suggests the
current working directory of the project is one directory too high.
Could you show the directory layout, including the location of
settings.py, admin.py for the app and views.py.

Sorry I worded that rather bad. Your goal is to connect to the page that
triggers a 500 error with one of the tools I mentioned so you can see
the actual response, not what your browser shows you as the browser
could be showing you it's own "server error" page.

Of course, you can still have the error in base.html.

See settings.py, the bottom part. If debug is set to 'off', 500 errors
are mailed to the DJANGO_ADMIN.

[ ] Make sure that absolute paths in settings.py point to actual
directories on the production server.

RE: cannot access admin

[lacrymol...@gmail.com]

Are you running admin.autodiscover? Does the admin homepage (/admin/) show your 
apps?

Asunto:  cannot access admin

So I don't normally spam forums/ mailing lists etc for help but I really 
screwed something up.  Basically when I try and access my admin site, for 
example:

DoesNotExist at /admin/auth/group/

Article matching query does not exist.

DoesNotExist at /admin/dotnet_forms/article/

Article matching query does not exist.

My urls

urlpatterns = patterns('',
(r'^media/(?P.*)$', 'django.views.static.serve', {'document_root': 
settings.MEDIA_ROOT }),
)

urlpatterns += patterns('',
url(r'^$', 'tacobakedotnet.dotnet_forms.views.home'),
url(r'^(\S+)/(\S+)', 'tacobakedotnet.dotnet_forms.views.home'),

# Uncomment the next line to enable the admin:
url(r'^admin/$', include(admin.site.urls)),
# Uncomment the admin/doc line below to enable admin documentation:
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
)

The website itself does work so the articles and things stored in the database 
are still there.  I just cannot access them.

I am asking because it seems like a technical problem of some sort.

I did add to settings.py but I don't think I changed anything.

This doesn't work either although the article is there when I pull it up inside 
the website.

DoesNotExist at /admin/dotnet_forms/article/12/

Article matching query does not exist.

So basically it seems like some kind of urlconf problem.

I'm not sure I follow...the \b just requires that a word-boundary
occur there, preventing it from matching something like "imgood".
It might even be vestigial as I originally had "*" rather than "+"
for the whitespace before attributes, so it could likely be removed
now without impacting the regexp.

I've done enough work where pathological client/user data comes
through that I swear sometimes they're TRYING to break the app.
Like the person who uploaded an Excel file with a .jpg extension to
try and post the contained graph (re. your PIL image-detection comment).

So it all boils down the use case, and how much work you want to
spend maintaining it every time it breaks.  If security is involved,
I want the best-tested library I can get so I don't have to make all
their mistakes myself.  If it's just a dirty "get me adequate data
as fast as possible" (especially if it's a one-off for a single
data-source), then I'll often just hammer it out using whatever is
easiest.

Re: Testing with LiveServerTestCase and Selenium

[Paul Childs]

I thought it might be a good idea to remove Django testing from the 
equation by opening up an IPython session and executing the following:

from selenium import webdriver
browser = webdriver.Firefox()
browser.get("http://www.microsoft.com/;)
browser.title
'' # empty string

The the same thing is happening with just the webdriver alone.

The company I work for has McAffee installed on my machine. Could it be 
blocking automated browser activity?

No clue. Connection timeouts are the like candidate but since you're not

No it doesn't. It can take a app.model name as well and is more commonly
used, since the primary use case for dumpdata is to provide seeds for
semi-static data, like a categories table.

This misses a unique index on (unipart_id, category_id) but doesn't
explain the issues you're seeing.

Any chance we can see the actual models and one broken record as
outputted by dumpdata?

Help getting my first django site deployed! (heroku)

[Matthew Meyer]

Hello all!

I am in the process of deploying my first django site: 
http://pure-mist-4298.herokuapp.com/

Currently, I have two major issues I am unsure how to resolve.

1. Something is messed up with my database settings. 
I followed this tutorial to get started: 
https://devcenter.heroku.com/articles/django and initally everything worked 
out well. but upon trying to run syncdb a day later I run into the 
following error: http://dpaste.org/hhfCT/

I think this must be something to do with my database config in settings.py 
but since I followed that tutorial and they gave me a premade one line db 
setting. I am hesitant to change it. 

2. Once that is resolved, as is easily seen on the site, I am also having 
an issue using s3 with my static files. I was under the impression heroku 
automatically ran collectstatic when you pushed, there by collecting all my 
static files to my s3 bucket and everything would just work. 

Here is my setttings.py, where I think all the trouble is happening: 
http://dpaste.org/m2ftk/ SEE THE BOTTOM OF THE FILE for my production 
settings.

The sqlite db create in my dev enviornment is not deployed cause I have it 
in a .gitignore.

Any help is appreciated, thanks!

Why? Sisters are family, but don't inherit from each other and this is a
sister relationship. The only thing they have in common is the stuff
surrounding the data. One has a form.as_p the other is a loop based on
different variable. You're going to end up with more if statements than
code saved.
What you can do, is create a shared parent that does the page_title,
headline and so on for you, so that you only have to provide the content
block. So this would be a base_notes.html which extends base.html and
has an empty content block.

Re: specify the foreign keys in a ManyToManyField created table?

[eiriks]

I've tried (among many things) to set the person in Dagensrepresentanter to 
primary_key=True.  

person = models.ForeignKey(Personer, primary_key=True, 
related_name='dagensrepresentanter_person')  

to force the relationship to include the "right" id. This seems to do just 
that. I'm unsure if this has any other implications for me, but as for now

Re: Forms for updating a compound model

[Tomas Neme]

I'm sorry to tell you that ModelForms don't seem to have this
functionality, but I'm happy to tell you that ModelAdmins do.

What it does, basically, is to return this:

{
 'label': label_for_field(field, self.opts.model, self.opts),
 'widget': {
   'is_hidden': False
 },
 'required': False
}

when there's a field marked as readonly, so it can transparently be used
from the templates.

I recommend you go look at the code in
django.contrib.admin.helpers.InlineAdminFormSet to get a feel of what you
can do.

Annd... looking around, I found a ReadonlyWidget, look at the first answer
here:

Bill,

Re-reading the update() documentation and the way I implemented the
middleware, you are right that auto_now will be the best solution. I
will use save() instead of update() and will get that fixed.

Thanks a lot for the suggestion!  If you have any ideas about the
values() and order_by() issue, I will be happy to hear them!

Cheers,

Re: values() and order_by()

[J. Javier Maestro]

Hi there!

Thanks a lot for the reply. However, I don't think your solution would
work in my case, nor it answers the question of whether it can be done
or why the order_by() adds stuff to the GROUP BY clause when used in
conjunction with values().

Let's see:

I know about auto_now and, apart from the discussions that can be
found all over the Internet, is a nice feature... unless you update
records (like I do). Then, auto_now does nothing since it only affects
save(). In any case, the default value is actually a leftover from the
initial implementation, right now is not even needed.

First, this won't work in my implementation. My model stores the
actual count of a given visitor in the count_visits field and the
field is updated every time the visitor visits a user profile (via a
middleware and an F() expression) while your solution stores a full
record every time you want to log a visit to a user profile.

Logging visits your way will eat quite a bit of space in the database.
Also, it's not only about saving space and it's not only about two
database queries. In your implementation, the count() will scan the
whole set of records for the given user. This scan will grow with the
number of records and in this case, taking into account that the whole
purpose is to show a counter for visits to a given user profile... I
think that your proposed workaround does not really fit.


So, I ask again: Why the order_by('colum') when used in conjunction
with values(), adds the column to the GROUP BY?

Thanks,

In general Apache is easier to configure than nginx, but I find this not
to be the case with wsgi. If you're not set on Apache, then I suggest
you read the uwsgi deployment guide in the manual. I (and others on the
list) will gladly help you with the nginx bit, but I'd rather not
confuse you more if you're set on Apache, so I'm holding off on the
examples for now.

specify the foreign keys in a ManyToManyField created table?

[eiriks]

I have a model that auto created an auto inc id field as primary key. It 
related smoothly with my person model, but when I try to create a relation 
to committees (Komiteer) I get a new intermediate table with (an auto inc 
primary key, that's ok, a working relation to commitees, smooth and *a non 
working wrong data type field* that I'd expect to link to persons)

Heres the model with the ManyToManyField:

class Dagensrepresentanter(models.Model):
person = models.ForeignKey(Personer, 
related_name='dagensrepresentanter_person')
vara_for = models.ForeignKey(Personer, blank=True, null=True, 
related_name='dagensrepresentanter_vara_for')
komiteer = models.ManyToManyField(Komiteer)

it generats this intermediate table (I only included the fields 
for simplicity):

  `id` int(11) NOT NULL AUTO_INCREMENT,
>   *`dagensrepresentanter_id` int(11) NOT NULL,*
>   `komiteer_id` varchar(150) NOT NULL,


The line in italics is a int(11), and probably links fine with the auto 
generated id in the model for Dagensrepresentanter but it need to link to 
the person field. In the person table the datatype for this value is 
varchar(33) 
NOT NULL

How do I specify that the foreign key in the intermediate table is the 
person field from the Dagensrepresentanter model?

Aside from the \b matching positive against ><, this is a syntax
validator and of course when validating syntax you'll use a validating
parser. For all other cases, you'd be more interested in "image tags
with a src attribute", making the use-case quite a bit more simple.

My main beef with modern software is that for the simplest of things one
flees to full-blown libraries which happen to provide some utilities,
but the other 98% of the code from that library is unused. Case in
point, PIL to verify if a file is an image. But my rant alarm went off. :)

But the author I replied to did. I think you and I are on the same page.
Either way, the OP now has some nice examples of how to /refine/ regular
expressions and that's the real craft :).

Upgrades aren't solutions. They only dress up as them in their spare time.

You should:
1) Identify where you generate links via javascript
2) Identify what javascript variable is passed to the link
3) Identify how it can be undefined

If you don't see how it can be, undefined, use the appropriate
javascript forums / documentation.

If request.user.is_anonymous() is True you have your answer. If not,
figure out what kind of stuff is in that object by printing it's __dict__.

Admin actions -- short_description as doc string?

[Roy Smith]

I'm just staring to explore admin actions.  I'm surprised to see that you have 
to set the description by doing:

my_action_function.short_description = "blah"

wouldn't it be cleaner to just declare a doc string for the action function and 
have short_description grabbed from there?

onetoone relation question

[ledzgio]

Hi all,

I have the following configuration:

models.py http://dpaste.org/9q79R/
admin.py http://dpaste.org/w7CCD/

In admin I will get a select where for each player I can select (or add a 
new one) PlayerAttribute object. With the onetoone relation I have one 
PlayerAttribute for one Player but in the admin every player can choose one 
PlayerAttribute from the previously added. WHat I want is that if I add a 
new PlayerAttribute (from the Player admin panel), that PlayerAttribute is 
only associated with that player, so if I add another Player I will not 
able to choose the previously added PlayerAttribute but I can just add a 
new one (or choosing an older PlayerAttribute associated to that player).

How can I do that?

thanks

You're also returning mimetype="application/json" outside of the

edit form cannot be generated for django comments

[Sachin Gupta]

I wanted to have a functionality to be able to edit the comments posted 
using the comments app (not from the admin, from the site). As much as I 
know Django, to render an edit form we need to pass an instance of the 
object to the form which has to be edited like

form = SomeForm(instance=some_object)

But when I try to do the same in case of CommentForm imported from 
django.contrib.comments.forms, I get an error  __init__() got an unexpected 
keyword argument 'instance'.
When I check the comment form I find that the __init__() for the comment 
form is overwritten and it does not accept the `instance` argument. If the 
form cannot accept this argument, it means I cannot generate an edit form.

Is there any work around?

Thanks,
Sachin
