Internal links from templates

[danialt]

I have looked around to find out how to link directly to a fluent_page. Say I have 1 page with 2 translations:

1. About Company, Slug: about-company, layout: about_company.html
2. Über Firma, Slug: ueber-firma, layout: about_company.html

How can I link to the root of these pages that when say /de/ is activated it goes to the German version of the content and not the english one?

You should review the django-parler app.

http://django-parler.readthedocs.org/en/latest/
https://github.com/edoburu/django-parler

I'm not sure I understand exactly what you asking but I think this close to what you need:

{% load parler_tags %}
{% get_translated_url page.language_code about_page as about_page_tr_url %}

Where page is the current page. And about_page_tr_url will be the link to the page with the current language code.

@vinnyrose
Thank you for your input. Sorry if I was not clear. Your solution works indeed for the current page.

However, I'd like to link to a fluent_page node from another app/template. Say I am in books app and I want to put a link to "about us" page. How can I do that?

Thank you in advance.

If you're looking to render a menu I would look at some template tags:
http://django-fluent-pages.readthedocs.org/en/latest/templatetags.html#the-menu
or
http://django-mptt.github.io/django-mptt/templates.html

If you just want to link to the about page then you can get the about page in your view by either by get_for_path() (http://django-fluent-pages.readthedocs.org/en/latest/api/models.html#fluent_pages.models.UrlNodeManager.get_for_path) or use FLUENT_PAGES_KEY_CHOICES (http://django-fluent-pages.readthedocs.org/en/latest/configuration.html#fluent-pages-key-choices)

@vinnyrose Thank you very much. I think you are on the right tangant.

from fluent_pages.models import UrlNode
from fluent_pages.models.navigation import PageNavigationNode
from fluent_pages.models.utils import prefill_parent_site

UrlNode.objects.get_for_path('/uber-firma/').get_absolute_url()

gives me this error:

I am trying to get the node for "uber-firma", which is "de" default language, and then display "about-company" link in the template. Is there any easier way to do this, e.g. a template tag?

Many thanks!

If you have some special page where you want to link to, you can also use Page.objects.get_for_key("...") function.

If you define FLUENT_PAGES_KEY_CHOICES in your settings file, you can select a "page identifier" in the admin (hidden under the "Publication preferences").

I use this to link to a "Terms and conditions" page or contact page.

For regular content, I'd use a menu as @vinnyrose suggested.

The exception you get happens because PyDev hooks the import code. You can fix this by running pip install django-fluent-utils>=1.1.2.
