Randomize talks order

[rnditdev]

In order to avoid statistical bias, randomize the talks before presenting them.

{% for t in talks %}

I think it should be enough to replace
{% for t in talks %}
by
{% for t in shuffle(talks) %}

Thanks for the suggestion. The django template language does not allow the use of python functions in the templates: ordering must be done at the queryset level

Thank you for the correction, I see that the line to apply the shuffle (in case my suggestion is accepted) is

conference/conference/views.py

Line 739 in 7e5d9c4

talks = talks.order_by('speakers__user__first_name', 'speakers__user__last_name')

talks = talks.order_by('speakers__user__first_name', 'speakers__user__last_name')
should be
talks = shuffle(talks)

It could also apply to:

conference/conference/views.py

Line 575 in 7e5d9c4

talks = talks.order_by('speakers__user__first_name', 'speakers__user__last_name')
