I have a Django model that records the user who created a record. I want to display a button on a template only if the user logged in is the same as the user on the record.
I want to do something similar to:
{% if user.is_authenticated and (request.user.is_superuser or request.user == task.user) %}
where task is the record.
How can I do this?
You can't use parentheses in the {% if %} template tag. You can use the following check which is equivalent:
{% if user.is_authenticated and request.user.is_superuser or user.is_authenticated and request.user == task.user %}
You can then drop the first user.is_authenticated check, because only an authenticated user will be a superuser.
{% if user.is_authenticated and request.user.is_superuser or user.is_authenticated and request.user == task.user %}
You may also be able to drop the second user.is_authenticated check if all tasks have a user (since an anonymous user is never equal to a real user).
{% if request.user.is_superuser or request.user == task.user %}
Django discourages putting complicated logic in the template. In this case, you might be able to put the logic in a filter, and then your template would simplify to:
{% if task|display_button:request.user %}...{% endif %}
