如何在页面上检查用户的权限？

Question

I need to allow the user to see some parts of a page according to his permissions.

I've seen some answers here like using @user_passes_test ( Django - user permissions to certain views? ) and checks on the template ( Should I use Django permissions checks in the template AND the view? ).

In the latter @e-satis ' answer states that for my case I should use checks at the template.

My question is: How can I do this and what is the best way (performance and security wise) to do so?

To exemplify my need I thought about Facebook. In Facebook you allow certain users to see some parts of your profile page or all of it. That's exactly the behavior I need to implement.

I appreciate your thoughts.

Thanks.

Answer 1

it's in the django docs

basically

{% if perms.foo %}
    <p>You have permission to do something in the foo app.</p>
{% else %}
    <p>You don't have permission to do anything in the foo app.</p>
{% endif %}

Answer 2

Based on your examples, I'm assuming you mean permissions in the context of the Django package and not authentication-checking (is_authenticated()). This is actually pretty straight-forward and given fully in an answer e-satis ' gives here .

edit Looks like a better answer was given.
