Documenting use of get_obj_perms when looping over an object list within template

[kierer]

I am using a class-based view (ListView) and have code that is structured as follows in the template. The permission check is returning false when I would expect the delete_widget permission to be present in the widget_perms for objects in the collection for the logged-in user. Am I using get_obj_perms incorrectly within a looping structure? If so, might an example of how to use it correctly when looping over an object list in a template be added to the docs?

{% load guardian_tags %}
{% block content %}
    {% if object_list %}
        {for widget in object_list %}
            {% get_obj_perms request.user for widget as "widget_perms" %}
            {% if "delete_widget" in "widget_perms" %}
                <a href="/widget/delete/{{ widget.pk }}" class="btn btn-danger" role = "button">Delete</a>
            {% endif %}
        {% endfor %}
    {% endif %}
{% endblock %}

Thanks!

See #382.

Thank you! I hadn't realized that prefetch_perms support had been added to guardian_tags for use in templates (I was going by the docs and thought only get_obj_perms was available). I'll give it a shot tonight.

It looks like prefetch_perms isn't (yet) supported in guardian_tags. I just went with a less elegant approach- adding a deletable_widgets collection to the context with a get_context_data override on the (class-based) view, then in the template

{% if widget in deletable_widgets %}
                <a href="/widget/delete/{{ widget.pk }}" class="btn btn-danger" role = "button">Delete</a>
{% endif %}
