Because there is no solution. You must rewrite the custom tag to set a
variable in the context, which you can then test in your 'if' tag.

The link in my first email explains how to do that.

Using the backend database to secure a page on the frontend

[vanderkerkoff]

Hello there

I"m sure this question has been answered before but I just can't find
it, apologies.

We've got a django 1.1.2 site and I need to secure some sections of
the frontend, and use the users and groups model in the backend as the
database to provide authentication.

I really don't know where to start to be honest.

Any links to examples would be great.

What would be really great is if there's a way in the urls.py file to
do something like this.

from django.contrib.auth.models import *
urlpatterns += patterns('django.auth.authenticate',
   (r'^specificurl$',")
)

If I get it working on specific URLS first, I can then start to work
out how to incorporate the login section into parts of the app.  So
people could tick a page say as restricted, and then people would have
to login to see the page.

Any tips or links off to documentation would be really helpful.

Thanks

Re: Using the backend database to secure a page on the frontend

[Philip Mountifield]

If you want to use the existing permission system, I think you'll find 
this is what you need: 
https://docs.djangoproject.com/en/1.4/topics/auth/#the-permission-required-decorator


You could add some extra permissions to your models too if you need 
them: https://docs.djangoproject.com/en/1.4/ref/models/options/#permissions


Kind regards
Phil

Tweepy Image and Link display

[coded kid]

Hi guys, how can I get users twitter handle with link and display
their image in my django app. What I mean is this, I want the users
username should be clickable (so that when I click on it it will
direct me to the user profile), and display the user profile image by
their update. I hope you get my point?

Below are mu codes:

Views:

def tweetstream(request):
consumer_key=""
consumer_secret=""
access_token=""
access_token_secret=""
auth=tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api=tweepy.API(auth)
statuses=api.friends_timeline(count=30)
for status in statuses:
status.__getstate__()
return render_to_response('tweets.html',{'statuses':
statuses}, context_instance=RequestContext(request))

Templates:

{% extends "base.html" %}


 {% block content %}


 {% for status in statuses %}
{{ status.author.screen_name}} :
   {{ status.text|safe }}  
  {{ status.created_at }}  Via: {{status.source}} 
{{ status.profile_image_url }}

 {% endfor %}

Re: Using the backend database to secure a page on the frontend

[vanderkerkoff]

Thanks for getting back to me Phillip.

I'm using that page as a guide, and i've got a pages application that
has a registration_required boolean field setup.

In my urls file I've got this

(r'^login/$', 'django.contrib.auth.views.login'),

In my page view I'm doing this

print pg.registration_required
print request.user.is_authenticated()
if pg.registration_required and not request.user.is_authenticated():
  return HttpResponseRedirect('/login/?next=%s' % request.path)

I've setup the auth middleware and pg is the page.

I can see that pg.registration_required is true, and that
request.user.is_authenticated() is false, so the code is trying to
send me to the login page.

The docs say to create registration/login.html as that is the default.

I've created a folder called registration in my templates folder, and
a page called login.html in that folder, but the site is still
throwing me a template not found error

Request Method: GET
Request URL:http://127.0.0.1:8000/login/?next=/helpline2/
Django Version: 1.3 beta 1 SVN-15046
Exception Type: TemplateDoesNotExist
Exception Value:registration/login.html

I must be doing something dull, anyone got any ideas?

Sorry everyone, but this is driving me crazy

Re: Doing something silly, I'm sure

[Bill Freeman]

Are you in debug mode so that the stack trace is displayed (on the development
server)?  Have you looked at the local variables in the trace to see
what template
it is trying to find?  Are the permissions on the template such that django can
read it?  On the development server, pdb.set_trace() is your friend. (Actually,
I've just learned how to use pdb under mod_wsgi, but you don't really want to
do that unless you can't duplicate your problem under the development server.)

(I like top posting.  It keeps me from having to scroll past stuff
I've already read.)

FYI to others, the stacktrace indicates OP is using 1.3 beta 1.

You should just use the login_required decorator instead of rewriting it.

Also, I'm not sure why you are showing us view code. Your urlconf says
that you are pointing at the stock auth view, so why this snippet?

So, nothing to do with auth, the real question is "Why isn't my
template found". OK. First things, stop using a beta. Update your
django to 1.3.1, so we can rule out any bug in the beta.

Next, you say you "created a registration folder in my templates
folder and a login.html file in there". Where is this template folder?
Show us the structure of your project and your pertinent apps.

Cheers

Tom

Working with List in Tweepy

[samuel ayo]

Hello, how can I make users create their list in my django app 
automatically? Since the  API.create_list() required parameters before it 
would work; 

*

Creates a new list for the authenticated user. Accounts are limited to 20 
lists.

Parameters: name (Required), mode (public/private default: public)

Returns: class:List object
*

So I want users to be able to create their list through my own app 
automatically and since I don't know the name they want to give their list 
and the member they want to add, how can I do it automatically?

Please kindly help me out! Thanks.

Re: Http404 and process_exception

[Justin Holmes]

Russell,

Yeah, I see the inconsistency there, and my first thought was that
this is a bit backward.  However, the underlying distinction here is
that it's not the 404 (ie, the resource gone missin') that is the
exception but the Http404 object.

It remains straightforward enough for a developer to simply return
HttpResponseNotFound if they don't want their business logic treated
as an exception.

(Maybe this belongs on -dev) I do, however, think that the
get_object_or_404 documentation can be clearer that, as with .get(),
either failing case raises an exception.  Perhaps change the note to:

"As with .get(), an exception is raised unless exactly one object is
found for the given parameters.  A MultipleObjectsReturned exception
will be raised if more than one object is found.  However, unlike
.get(), Http404 is raised if no object is found."

This may not be necessary at all, as the Http404 page makes it clear
that it's an exception.

Implementing Tagging with Django

[puddy]

Hello,

I searched for tagging libraries for Django and found two (django-
tagging and django-taggit) but both are fairly old and haven't been
maintained.  I'd like to implement some sort of tagging on my site - a
bookmarking type service where each link has a set of tags.  I know of
how I would like to model the data at the DB level:

Bookmark Table:
bookmark_ID,title,link

Tag Table
tag_id,tag_name

TagWithBookmarkTable
tag_id,bookmark_id

I'm not quite sure how to do this at the Django Models level
though.Anyone able to help?: I feel like this is a common problem but
I haven't had much success with google searches for django tagging -
keep getting template tag results or old blog posts (maybe I should
just follow them?).

Thanks!

How can I best create a blog that works similarly to Tumblr?

[Willy]

I know the question is kind of poorly phrased. But here goes, I've been 
working on a blog software and I want to have five distinct post types (in 
the same way Tumblr does) but I'm having a hard time figuring out how to 
create my index view and detail views as they are currently five different 
models that inherit from the same abstract base model.

Here is my models.py http://dpaste.com/724371/
as well as my views.py http://dpaste.com/724372/
and for safe measure, my urls.py within the app http://dpaste.com/724373/

How can I make this work? The current hack of using chain() isn't really 
working out because of the fact that it returns a list, not a queryset.
All together I feel like my code is quickly becoming unmaintainable but I 
would really like to know how to get this working as its early enough in 
the development to change.

Re: Implementing Tagging with Django

[Willy]

Django-taggit works quite well, I would suggest trying it over 
django-tagging. Even if it hasn't been updated in a while it's still a good 
solution, and you could always make changes to it and fork your own version 
if it doesn't meet all your needs.

changelist link in change_form.html

[Lee]

I know this has to be simple but I'm not finding it in the archives or
google. I just want to include a link to the corresponding changelist
in every add/edit form. I assume I need to update the change_form.html
template, but what is the correct syntax to display the changelist
URL? A 1.3-compatible solution would be best.

Thanks for any help or ideas.

Questions about UnicodeDecodeError

[Ali Mesdaq]

I have a situation where I am reading data that I have no control over and
inserting it into a db. The data is http headers. I am storing them in
postgres db in a text field and the db encoding is SQL_ASCII. Since the
data can be anything even non compliant http headers with anything for its
values I don't want to modify the data before I store it in the db.
However this is causing issues with certain values causing the
UnicodeDecodeError. For example I have a specific case where the user
agent is set to 'KC\xd4\xda\xcf\xdf\xc9\xfd\xbc\xb6'. I have been trying
to look for a way to deal with these cases gracefully in the models
__unicode__ method but nothing I have tried has worked.

Re: django-admin change form page validation

[Nikhil Verma]

Hi

I understand that but the problem is its a condition which i have to add if
the revisit checkbox is selected and then in interview_type dropdown None
option is selected ; after pressing save it should throw an error .

None is an option in the dropdown . It is not blank=True and null =True

INTERVIEW_TYPES = (

('default', 'None'),
('Paired Visit','Paired Visit'),
('Time Series', 'Time Series'),

),

interview_type will show choices with dropdown 1) None 2) Paired Visit 3)
Time Series

ok. in admin,.py file


override the response_change method

def response_change(self,request,obj)

obj is the handler

so u can check using obj.field_name and take approp action

It sounds like most of your problems originate from the fact that you're using 
an abstract base class for posts.

If you make BasePost non-abstract, then you'll be able to generate a queryset 
of BasePost objects, rather than having to chain through querysets of the 
concrete subclasses. Once you have a BasePost instance, you can retrieve the 
specific details associated with each instance with a single attribute request. 
It also means that when you start introducing links to posts, you won't need to 
maintain 5 different foreign key types (i.e., link to a text post, link to an 
image post, etc) -- there's just one "link to a post".

The detail view is also simplified -- it's a detail view for BasePost, not some 
hybrid that is trying to handle 5 different subclasses.

The only other thing you might want to change is to make post_type a field on 
BasePost; this isn't strictly required, but it will make it easier to do 
CORBA-style "narrowing" (i.e., I have a BasePost instance; what type of Post is 
it, and how do I get an object of that type?).

Hope this helps!
 
Yours,
Russ Magee %-)
