Re: How to read part of many-to-many field in the template

[Elliot Bradbury]

Hi Mohammad,

Check out slice
.

It's a builtin template filter that can be used like this:

{% for author in book.authors.all|slice:"3" %}
  {# HTML up in here #}
{% endfor %}

Good luck,
Elliot

Re: Creating a Node in Django ORM

Check out django-mptt for creating parent/child (tree) relationships
between models. https://github.com/django-mptt/django-mptt

Re: Problem with django 1.5.1

[Elliot Bradbury]

Hey kl4us,

I think the problem is that you need to specify the URL name as a string,
like: {% url 'post' slug=post.slug %}

Re: TDD with Django/Splinter/plupload queue

[Elliot Bradbury]

PhantomJS is a headless webkit browser that can be programmed to perform
automated webpage tasks (like maybe select a file for upload). The standard
API is Javscript but I believe there is a Python port. Maybe that could
help?

Re: Tutorial three '-pub_date'

[Elliot Bradbury]

'-' reverses the ordering of that field. So it will order the most recently
published Polls first.

Re: Google Drive with Django?

[Elliot Bradbury]

django-social-auth has some Google OAuth2 code. I'm not sure if it applies
to Drive but it might be worth looking at. I was able to create an OpenID
backend to a new service in about 2 minutes.
