Playing a GIF with Django
Trying to get a gif to play on a single page website i'm developing. For some reason it's not displaying or playing properly. I'm using Django with Python as a backend and just simple HTML with Bootstrap as a front end. Really appreciate the help. Here's the code. <div class="col-xs-6 nopadding full-screen force-full-screen dark videoplay-on-hover"> <div class="vertical-middle ignore-header center"> <h2 class="nobottommargin ls1 font-body">different.</h2> </div> <div class="video-wrap"> <video id="slide-video" poster="{% static 'img/videos/1.jpg'%}" preload="auto" loop muted> <source src="{% static 'img/videos/1.webm' %}" type='video/webm' /> <source src="{% static 'img/videos/1.mp4' %}" type='video/mp4' /> </video> <div class="video-overlay" style="background-color: rgba(0,0,0,0.2);"></div> </div> </div> When I use the {% static ...%} for images it works fine. I don't really understand why it would be different for webm or mp4 type files. Thanks in advance! -

uWSGI downtime when restart
I have a problem with uwsgi everytime I restart the server when I have a code updates. When I restart the uwsgi using "sudo restart accounting", there's a small gap between stop and start instance that results to downtime and stops all the current request.

Change form field value in django, after __init__ but before cleaning

How do I get rid of the value, so that the change takes effect in the template, which renders the form? Things that don't work: Setting the initial parameter. Since there is a value present, it will be ignored Using cleaned values. The form is not cleaned at this stage, since it is not valid. Because of this cleaned_data does not exist I'm accessing the values like this: {{ form.field1.value|default_if_none:"Please enter." }} -
