Template examples
#################
.. highlight:: html+django
First you have to load the ``embed_video_tags`` template tags in your template:
::
{% load embed_video_tags %}
Embedding of video:
::
{# you can just embed #}
{% video item.video 'small' %}
{# or use variables (with embedding, too) #}
{% video item.video as my_video %}
URL: {{ my_video.url }}
Thumbnail: {{ my_video.thumbnail }}
Backend: {{ my_video.backend }}
{% video my_video 'small' %}
{% endvideo %}
Default sizes are ``tiny`` (420x315), ``small`` (480x360), ``medium`` (640x480),
``large`` (960x720) and ``huge`` (1280x960). You can set your own size:
::
{% video my_video '800x600' %}
.. versionadded:: 0.7
This usage has been added in version 0.7.
.. versionadded:: 0.9
And use relative percentual size:
::
{% video my_video '100% x 50%' %}
It is possible to set backend options via parameters in template tag. It is
useful for example to enforce HTTPS protocol or set different query appended
to url.
::
{% video my_video query="rel=0&wmode=transparent" is_secure=True as my_video %}
{{ my_video.url }} {# always with https #}
{% endvideo %}
.. tip::
We recommend to use `sorl-thumbnail
<http://sorl-thumbnail.readthedocs.org/en/latest/>`_ to `change
<http://sorl-thumbnail.readthedocs.org/en/latest/examples.html#template-examples>`_
thumbnail size.
.. tip::
To speed up your pages, consider `template fragment caching
<https://docs.djangoproject.com/en/dev/topics/cache/#template-fragment-caching>`_.
.. tip::
You can overwrite default template of embed code located in
``templates/embed_video/embed_code.html`` or set own file for custom
backend (:py:data:`~embed_video.backends.VideoBackend.template_name`).
.. versionadded:: 0.9
``template_name`` has been added in version 0.9.
Model examples
##############
.. highlight:: python
Using the ``EmbedVideoField`` provides you validation of URLs.
::
from django.db import models
from embed_video.fields import EmbedVideoField
class Item(models.Model):
video = EmbedVideoField() # same like models.URLField()
Admin mixin examples
####################
Use ``AdminVideoMixin`` in ``admin.py``.
::
from django.contrib import admin
from embed_video.admin import AdminVideoMixin
from .models import MyModel
class MyModelAdmin(AdminVideoMixin, admin.ModelAdmin):
pass
admin.site.register(MyModel, MyModelAdmin)
Custom backends
###############
If you have specific needs and default backends don't suits you, you can write
your custom backend.
``my_project/my_app/backends.py``::
from embed_video.backends import VideoBackend
class CustomBackend(VideoBackend):
re_detect = re.compile(r'http://myvideo\.com/[0-9]+')
re_code = re.compile(r'http://myvideo\.com/(?P<code>[0-9]+)')
allow_https = False
pattern_url = '{protocol}://play.myvideo.com/c/{code}/'
pattern_thumbnail_url = '{protocol}://thumb.myvideo.com/c/{code}/'
template_name = 'embed_video/custombackend_embed_code.html' # added in v0.9
You can also overwrite :py:class:`~embed_video.backends.VideoBackend` methods,
if using regular expressions isn't well enough.
``my_project/my_project/settings.py``::
EMBED_VIDEO_BACKENDS = (
'embed_video.backends.YoutubeBackend',
'embed_video.backends.VimeoBackend',
'embed_video.backends.SoundCloudBackend',
'my_app.backends.CustomBackend',
)
Low level API examples
######################
You can get instance of :py:class:`~embed_video.backends.VideoBackend` in your
python code thanks to :py:func:`~embed_video.backends.detect_backend`:
::
from embed_video.backends import detect_backend
my_video = detect_backend('http://www.youtube.com/watch?v=H4tAOexHdR4')
