Social meta tags mixin for django-meta
Project description
Concepts
django-meta-mixin provides a mixin to handle metadata in your models.
Actual data are evaluated at runtime pulling values from model attributes and methods.
To use it, defines a _metadata attribute as a dictionary of tag/value pairs;
tag is the name of the metatag as used by meta.html template
value is a string that is evaluated in the following order:
model method name (which is called without argument at runtime)
model attribute name (evaluated at runtime)
string literal (if any of the above exists)
If value is False or it is evaluated as False at runtime the tag is skipped.
To use this mixin you must invoke as_meta() on the model instance for example in the get_context_data().
Installation
From PyPi:
pip install django-meta-mixin
From github:
pip install -e git+https://github.com/nephila/django-meta-mixin#egg=django-meta-mixin
Usage
Add to installed apps along with django-meta:
INSTALLED_APPS = [ ... 'meta', 'meta_mixin', ]Configure django-meta according to documentation (https://bitbucket.org/monwara/django-meta#rst-header-installation)
Add meta information to your model:
from django.db import models from meta_mixin.models import ModelMeta class MyModel(ModelMeta, models.Model): name = models.CharField(max_length=20) abstract = models.TextField() ... _metadata = { 'title': 'name', 'description': 'abstract', ... }Push metadata in the context using as_meta method:
class MyView(DetailView): ... def get_context_data(self, **kwargs): context = super(MyView, self).get_context_data(self, **kwargs) context['meta'] = self.get_object().as_meta() return contextInclude meta_mixin/meta.html template in your templates:
{% load sekizai_tags %} <html {% render_block 'html_extra' %}> <head> {% include "meta_mixin/meta.html" %} </head> <body> </body> </html>
Note
For Google+ support you must add {% render_block ‘html_extra’ %} in your template to add object type definition. See relevant Google+ snippets documentation (https://developers.google.com/+/web/snippet/)
