Q:

Can I use djangocms plugins in a conditional extended page? 

I have this at the top of my djangocms page template
{% extends request.user.is_authenticated|yesno:"member_template.html,base.html" %}

My plugins are not working with this setup.  But if I do this
{% extends "member_template.html" %}

My plugins work.  Is there a way to fix that?  I want that conditional. 

A:

Let's assume you're using render in your view. 
if request.user: base_file = "member_template.html"
else: base_file = base.html
render(request,'my_html.html',
               {'base_file' : base_file})

And then your extends tag looks like:
{% extends base_file %}
