Вопрос:

Я использую django-avatar, и мой шаблон имеет:

 {% load i18n avatar_tags %}
{% render_avatar avatar 100 %}

и я получаю эту ошибку:

Это так странно, потому что в другом шаблоне это работает без ошибок.

Можете ли вы мне помочь? Спасибо.

Ответ №1:

Из документов django-avatar:

{% render_avatar avatar [size in pixels] %}

Учитывая фактический avatar.models.Avatar экземпляр объекта, отображает HTML img тег для представления этого аватара в запрошенном размере.

Итак, на ваш взгляд, вам нужно получить аватар, связанный с пользователем: avatar = Avatar.objects.get(user=request.user )

Затем передайте эту переменную в шаблон.

1. как я могу импортировать модель аватара? аватар.модели. Аватар не работает.

2. Я скопировал весь каталог avatar в свой проект и теперь могу импортировать avatar. Проблема в том, что .get не работает, потому что MultipleObjectsReturned: get() returned more than one Avatar -- it returned 3 как я могу исправить?

3. Вы можете использовать . filter() вместо .get(), хотя вам нужно будет выяснить, какой из возвращенных аватаров следует использовать.

4. Исправлено с помощью: avatar = Avatar.objects.filter(user=target_user).order_by('-primary')[0]
