I've just marked the ticket ready for checkin. As soon as a commiter
has some free time, it will go into trunk.

Thanks for the contribution! May this not be your last :-)

DateTimeField(auto_now_add=True) and admin page

[DC]

Hi,

I have the following lines in my model:
entry_date = models.DateTimeField(auto_now_add=True)
pub_date = models.DateTimeField('date published', blank=True,
null=True)
last_change_date = models.DateTimeField(auto_now=True)

Basically, I want the entry date to be added automatically, and last
change date to be updated on every save(), just as described in
documentation. The problem is that those fields don't appear on the
admin page. I tried with explicitly setting those fields in my admin
class, per Tutorial:

class EcoPointAdmin(admin.ModelAdmin):
fieldsets = [
('Details', {'fields': ['title', 'description', 'type',
'status']}),
('Geo data', {'fields': ['latitude', 'longitude']}),
('Dates', {'fields': ['entry_date', 'pub_date',
'last_change_date']}),
]

But now I get the error shown below.

Any chance to have those fields on admin page, without creating my
custom admin? I couldn't find anything useful in the archives.

Thanks,
DC, Django novice

The error msg:

ImproperlyConfigured at /admin/ecopoint/ecopoint/3/

'EcoPointAdmin.fieldsets[2][1]['fields']' refers to field 'entry_date'
that is missing from the form.

Re: 404 only in Chrome

In urls.py:

Change:
(r'^portfolio/', include('project.urls.web')),

To:
(r'^portfolio/$', include('project.urls.web')),

The dollar sign makes it the end of the regular expression string. Without
it, /portfolio/ will match with /portfolio/funstuff,
/portfolio/?my_hax_rock, etc. See if that helps.

404 only in Chrome

[neridaj]

Hello,

For some reason I'm getting a 404 in google chrome when I visit /
portfolio/. The url entered is /portfolio/ but it returns as a 404 at /
portfolio/undefined/ in the chrome developer tools window. I read a
post about some issues with chrome handling errors and to resolve it
by unchecking "Use a web service to help resolve navigation errors"
but this didn't help with my problem. I'm not sure why undefined is
being appended to the url, any ideas?

urls.py:

(r'^portfolio/', include('project.urls.web')),

project/urls/web.py:

urlpatterns = patterns('django.views.generic.list_detail',
(r'^$', 'object_list', web_project_info_dict,
'project_web_archive_index'),
(r'^(?P[-\w]+)/$', 'object_detail', web_project_info_dict),
)

If it was a real 404 why isn't my error page displayed i.e., when I
visit /portfolio/non-existent-slug, I get the proper 404 page.

>>> django.VERSION
(1, 2, 0, 'alpha', 0)

Saving a blank OneToOne inline in the admin

[Dan Lipsitt]

How do I ensure that a blank InlineModelAdmin is saved when the parent
form is submitted? Here's a simplified version of my code:



class Flagset(Model):
group = OneToOneField(Group)
flag = BooleanField()

class FlagsetInline(TabularInline):
model = Flagset

class GroupAdmin(ModelAdmin):
inlines = [FlagsetInline]

admin.site.unregister(Group)
admin.site.register(Group, GroupAdmin)



When I save a new Group, I want a Flagset to be created whether the
Flagset.flag box is checked or not. If I leave it blank, no object is
created. I tried adding a signal handler like the following to create
the object:



@receiver(post_save, sender=Group)
def create_flagset(sender, **kwargs):
if kwargs['created']:
Flagset.objects.get_or_create(group=kwargs['instance'])



This works when the flag is not set, but causes an error if it is
(because the Flagset is created twice, it looks like).

What can I do to make this scenario work whether the inline is touched
or not?

Thanks,
Dan

Re: rendering CSV in response; need a little help

[Doug Ballance]

If you have a dataset that is too large to fit in memory comfortably,
the ability to pass a generator to an httpresponse means you can break
it up into multiple smaller queries (outside the template system
anyway):

def queryset_to_csv(queryset,delimiter=',',steps=500):
""" generator for large querysets """
try: # raw query set
fieldmeta = queryset.model._meta.fields
except AttributeError: # it's been evaluated
fieldmeta = qs._meta.fields
fields = []
row= []
for f in fieldmeta:
fields.append(f.get_attname())
row.append('"'+f.name+'"')

yield "%s\r\n" % delimiter.join(row)

ids=[o["id"] for o in queryset.values("id")]
count=len(ids)
for n in range(steps,count+steps,steps):
lo,hi=n-steps,n
qs=queryset.model.objects.filter(pk__in=ids[lo:hi])
it=[]
for i in qs:
row = []
for f in fields:
val =
str(getattr(i,f)).replace('"',"'").replace(delimiter,' ')
row.append('"'+val+'"')
it.append(delimiter.join(row))
yield "\r\n".join(it)

...
return HttpResponse(queryset_to_csv(somequeryset,',',
250),mimetype='text/csv')

Your way is right, nothing wrong wth storing templates in app directory.
For this purpose django even has special app loader, wich loads templates
stored in the app directory.

And this way your app would be closer to "just plug in and use"

As for me, i'm deciding where to store templates basing on app or project
requirements.

What's the django convention for templates?

[Mauro]

Hello, I'm totally new in the django universe and I'm trying out to build a 
little project.

There are many days who I'm following many tutorial on django framework. But 
it's not clear for me how the convention for templates is.

Following the djangobook I've build a projects who has the following 
strurcture:

projects |
 ---
| __init__.py
| manage.py
| settings.py
| urls.py

| app folder |
 --
   | many files
   | templates |

| 
index.php

As you can see the templates directory is stored inside the app directory.

Reading the django documentation instead they says that the templates dir 
should live inside the root directory of the projects.

I'm wondering, what's is the common convention about it?

I thought to store the templates dir inside each apps, because in this way 
the apps are more pluggables...I'm going wrong?

Thank you

Do you have a really good reason for generating CSV in a template? It
will be astonishingly slow.

The python csv module simply requires a file like object to write to.
A HttpResponse is a file like object.

To answer your question, in a for loop there are various counters
available, one of which is forloop.last, which is true the last time
through the loop.

Re: Walking the template / Partial rendering

[Alen Mujezinovic]

Also, here's the actual code that is used by the mixin to assemble the 
response:

https://gist.github.com/70beb521546d59deb207

Compare this to what is going on in  `ExtendsNode.render`:

https://code.djangoproject.com/browser/django/trunk/django/template/loader_tags.py#L103

The code in the gist does handle `{{ block.super }}` but it comes with the 
cost of duplicating a big part of the render method. Having the context 
assembly moved out of the render method in the `ExtendsNode` would already 
be a big step :)

rendering CSV in response; need a little help

[Sells, Fred]

I'm getting an http request from another server in our system and I need
to respond using a csv format.  I've seen the example in the docs where
the template looks like this:

{% for row in data %}"{{ row.0|addslashes }}", "{{ row.1|addslashes }}",
"{{ row.2|addslashes }}", "{{ row.3|addslashes }}", "{{ row.4|addslashes
}}"
{% endfor %}


However I would like my template to work with a variable number of
fields.  Short of doing a  ",".join(arow)  in my view, I'm not sure how
to do this without getting a trailing  "," in my output.  My view
snippet looks like this:

results = [ (s.a, s.b, s.c, s.d, s.e) for s in today]
return render_to_response('tuples2csv.txt',{'records': results},
mimetype='text/plain', context_instance=RequestContext(request))


My template looks like this at this time:
===
{% for row in records %}{% for value in row %}{{value}},{% endfor %}
{% endfor %}
===

The data looks like this - I've deleted much of the internal field
content since it is proprietary information

7:55,,,
8:55,,,
11:25,,,
8:25,,xxx,
=
I guess I can always convert this to a text block in my view and respond
with that, but it seems like I should be able to use the template system
for a more generic solution.  I've done a fair amount of googling on
this but keep getting to the same examples that are close but not quite
what I need.

If someone can clarify how to eliminate the trailing ","I would really
appreciate it.

Thanks, 
Fred.

Re: Walking the template / Partial rendering

[Alen Mujezinovic]

Hey Tom

I've had a look through previous tickets if something similar came up and 
also looked at the link you posted. It's the right direction, but not quite 
what I'm trying. Pulling out a single block from a template and rendering 
is easy. It breaks and throws an `AttributeError` though as soon as you've 
got a `{{ block.super }}` in the block you've pulled from the template due 
to the context not being fully assembled:

http://dpaste.com/hold/670841/

Also, say I want to pick the block "map" from the parent template will not 
work without first walking manually up the chain, and again, build the 
context:

http://dpaste.com/hold/670842/

mysite.contact.views might very well have a contact() method, but
mysite.books.views probably does not.

And you're importing 'views' a couple of times at the top. The last
"from mysite.books import views" is winning :-) You cannot have one
variable point to several things at the same time.

Best thing you can do:

import mysite.contact.views
import mysite.books.views
...
(r'^contact/$', mysite.contact.views.contact),

That worked and your explanation gave me a better understanding of how 
the process works.

That version is much easier to read :)

This ticket renders email contents from different blocks within a template:

https://code.djangoproject.com/attachment/ticket/17193/send_templated_mail.3.diff

Their code for finding and rendering a block looks pretty simple, and
doesn't require changes to core to achieve it. Could it be applicable
to your needs? Check out _render_block_node()

Cheers

Walking the template / Partial rendering

[Alen Mujezinovic]

Hi group
I considered posting this to django-dev or opening a ticket but
decided to erron the side of caution.
I've been looking thoroughly through django's template code the last
two daysbecause I'd like to render only parts of templates.
Pseudocode:
    tpl = Template("""        {% block someblock %}foo{% endblock %}
     {% block otherblock %}bar{% endblock %}    """)        node =
tpl.get_block("someblock")    result =
node.render(template.Context({}))
The motivation to do this is to get rid of the overhead that goes into
templates when dealing with reasonably AJAX heavy and complex
templates. Thinkof a template structure like this:
        {% block body %}        {% block map %}{%
endblock %}        {% block content %}{% endblock %}            {%
endblock %}            {% extends "body.html" %}
{% block map %}{% endblock %}    {% block content %}
     {{ object_list|unordered_list }}    {% endblock %}            {% extends "map.html" %}    {% block content %}{{
object }}{% endblock %}
Ideally when requesting the page that serves pin.html via AJAX we'd
want to serve only the content that is in {% block content %}. One way
to do this
        {% extends "map.html" %}    {% block content
%}{% include "pin-detail.html" %}{% endblock %}
And the corresponding view:
    def pin(request, id):        #...        if request.is_ajax():
        tpl = loader.get_template("pin-detail.html")
content = json.dumps(content = tpl.render(Context({'object': pin})))
         return HttpResponse(content, mimetype = 'application/json')
     return render_to_response('pin.html', {'object': pin})
This gets very tedious with time and isn't desireable.
So I came up with a mixin that gets rid of the repetition. It checks
if the request is AJAX'd and if so, renders all the blocks listed in
`self.partials`and `json.dump`'s the result to the HttpResponse. It
all works, except:
* {{ block.super }} does not work without resolving the whole chain of
parent  templates and building up the quite complex corresponding
context. It's   basically a copy of the first half of the
`django.template.loader_tags.ExtendsNode.render` method.
* Rendering blocks that are part of a parent template but not the
current one   fails because of the complexity of how the context for
the current and its  parent blocks are created. I figure building up
the context properly is   duplicating too much of django's internals
to be sane work.
Ignoring these two points, it all works very well - but I'd also like
to be able to render blocks that do make use of {{ block.super }} and
that can bedefined at any point in the template chain. Ideally the
`BlockNode`, `ExtendsNode` and `Template` classes would provide some
methods to walk the chain and build the context.
Are you guys interested in having similar functionality? It would
involve somerefactoring of the template internals and probably some
decisions of the corecomitters - I wouldn't really want to change the
`Template` class because itis the interface to adopt for third party
template languages.
Also, here's more pseudo code to illustrutate how the partial mixin
looks whenused.
    class PinView(PartialRenderingView):        template_name =
'pin.html'        # Blocks to render and dump as json when doing AJAX
requests         partials = ['title', 'pin', 'form']
def get(request, id):            # ...             return
self.render_to_response(request, pin = pin, form = form)
 def post(request, id):            # ...            return
self.render_to_response(request, pin = pin, form = form)

Anyway. Thoughts?

Building my own `like` system

[Alec Taylor]

I am thinking to build my own like system, as a way of learning
various technologies including Javascript; and to gain a better
understanding of authentication and XSS. Most importantly though, this
will provide a fun project with which to learn DJango.

Use-case:
1.Unique ID generated atop a little bit of Javascript code, for
embedding in any website
2.When unique user presses this like button, a +1 is triggered to
the 'score' of that UID
3.On unique user's profile, display what they like'd

I'm unsure as where to start... how would I go about building this
system? — i.e. Should I be looking at Pinax?

Thanks for all suggestions,

Alec Taylor

In MySQL, you can set the collation of your table to be case-insensitive. 
This affects all queries, though.

OP is talking about case insensitive ordering, not querying (and he

String problem about creating user

[Tsung-Hsien]

Hello
If I use register page to create user, the string of username and
email displays u'' on command line, and if I create user on
command line, the string of username and email display ''. the
difference is one has the 'u' and the other doesn't.

The important thing is:
When I want to filter the User object, the object views the string as
different character. Therefore,  I can't get what I want, and the
object always return [ ].
How to let the string does not display u'xxx' but 'xxx' ?

I have the question because the PasswordResetForm of django, and find
the User.objects.filter(email__iexact=email, is_active=True) always
return [ ]

and my view like this:
if request.method == 'POST':
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']
)


Thanks!

That is strange; it wasn't supposition, it was actual results from a
working project. Perhaps sqlite behaves differently to other DBs with
that query, as you can see from this data and transcript, it does
precisely what you asked for, using the ORM:


sqlite> select * from app_thing;

1   carrot

sqlite> select * from app_votecontext;
id  name
--  --
1   Flavour
2   Smell

sqlite> select * from app_vote;
id  thing_idcontext_id  user_id vote
--  --  --  --  --
1   1   1   1   2
2   1   1   2   4


>>> from app.models import *
>>> from django.db.models import *
>>> carrot = Thing.objects.get(name='carrot')
>>> u=User.objects.get(id=1)
>>> f=(Q(vote__thing=carrot) | Q(vote__isnull=True))\
...& (Q(vote__user=u) | Q(vote__isnull=True))

Doing a "star import" is almost always a bad idea. You don't know what 
you're importing. And you can override variables by accident that way. 
Better to explicitly import what you need.


In this case the problem was that the original poster imported 'view' a 
few times from different places. Doing a "*" import would only make that 
problem worse :-)
