Parentheses in django if statement

Question

How can I do this cleanly in a Django template? Basically if A, or (B and C) , I want to show some HTML.

I basically have this:

{% if user.is_admin or something.enable_thing and user.can_do_the_thing %}

Now, thats a bit ambigious. I tried doing

{% if user.is_admin or (something.enable_thing and user.can_do_thething) %}

But you arent allowed Parentheses. The docs say to use nested ifs (or elifs in this case, i guess, as its an OR) , but I dont want to repeat the same HTML inside 2 if blocks, which sounds horrible.

Answer 1

As Mihai Zamfir commented it should work as expected. As Django documentation mentions:

Use of both and and or clauses within the same tag is allowed, with and having higher precedence than or e.g.:

{% if athlete_list and coach_list or cheerleader_list %}

will be interpreted like:

if (athlete_list and coach_list) or cheerleader_list

Answer 2

you could do the check in your view and pass a flag to the context.

show_html = user.is_admin or (something.enable_thing and user.can_do_the_thing) context['show_html'] = show_html 

Then in your template you could check the flag

{% if show_html %}
