Storing CONTEXT-entities in YAML-files

In this example, data resides in ROOTPATH/data/stuff.yaml. It is read in settings.py and can then be used in all your templates and documents.

stuff.yaml:

 -
   name: "table"
   price: "100$"
 -
   name: "chair"
   price: "30$"

settings.py:

import yaml
DATA_PATH = ROOT_PATH + "/data"
CONTEXT['stuff'] = yaml.load( open(DATA_PATH + "/stuff.yaml") )

layout_example.html:

{% extends "skeleton/_body.html" %}
{% block content_body %}
{% for item in stuff %}
<p>A {{item.name}} is worth {{item.price}}.</p>
{% endfor %}
{% endblock %}

Django: Sorted looping over dictionaries

This is not hyde-specific, but a general Django issue. Suppose you have a dictionary of name abbrevs and full names

presidents = {
    'gebush': {'forename': 'George', 'surname': 'Bush'},
    'baobam': {'forename': 'Barack', 'surname': 'Obama'},
    'biclin': {'forename': 'Bill', 'surname': 'Clinton'},
}

Now, suppose you want to loop over the dictionary while sorting by surnames. Use the following Django template code:

{% for president in presidents.values|dictsort:"surname" %}
{{president.forename}} {{president.surname}}
{% endfor %}

Installing new Django apps and filters

In this example we want to obfuscate e-mail addresses with ROT13. It is as simple as that

• create a dir django/ in your hyde directory
• create the empty files django/mailobfuscate/__init__.py and django/mailobfuscate/templatetags/__init__.py
• Install the mail obfuscation snippet to django/mailobfuscate/templatetags/mailobfuscate.py
• add to your settings.py
  

  import sys
  DJANGO_PATH = os.path.join(ROOT_PATH, "django")
  sys.path.append(DJANGO_PATH)

• Add to INSTALLED_APPS in settings.py
  

  INSTALLED_APPS = (
      'hydeengine',
      'django.contrib.webdesign',
      'mailobfuscate',
  )

• In your content HTML file simply use
  

  {% load mailobfuscate %}{% filter obfuscate %}blablubb.org{% endfilter %}@
