Sorl-thumbnail: الصورة المصغرة غير مرتبطة بالصورة المصدر في مخزن القيمة الرئيسية

لقد لاحظت السلوك التالي:

تحتوي صفحتي على استدعائين للعلامة {% thumbnail %} template يطلب كل منهما صورة مصغرة لصورة المصدر نفسها بحجم آخر. مثله:

{% thumbnail user.get_profile.avatar_image "46x46" crop="center" as im %} .. {% endthumbnail %}
{% thumbnail user_profile.avatar_image "187x187" crop="center" as im %} .. {% endthumbnail %}

(يتم إجراء المكالمات من قوالب Django مختلفة)

إذا تعذر على sorl-thumbnail العثور على الصور المصغرة ، فسيتم إنشاؤها كما هو متوقع. ولكن لم تتم الإشارة إلى إحدى الصور المصغرة في الإدخال sorl-thumbnail||thumbnails||xxx في مخزن القيمة الرئيسية.

بعد عرض الصفحة ، يبدو مخزن القيمة الرئيسية كما يلي:

# select * from thumbnail_kvstore;
                             key                              |                                                                   value

(4 rows)

لماذا لا ترتبط إحدى الصور بالملف المصدر؟ هل هذا السلوك مقصود؟ (لأنني أعتقد أن هذا يتسبب في عدم حذف الصور المصغرة عند استدعاء sorl.thumbnail.delete .)

أنا أستخدم sorl-thumbnail==11.12.1b

هذا هو سجل Django لإنشاء الصور المصغرة:
