非常に単純なコードですが、奇妙な状況です...
このスニペットを含むテンプレートがあります:
{% is_contest story as iscontest %}
ここで、is_contestはこのカスタムテンプレートタグです。
@register.assignment_tag
def is_contest(obj):
contesttype = ContentType.objects.get_for_model(Contest)
return obj.source_content_type == contesttype
ただし、コンテストはdjango_content_typeテーブルにあります。
奇妙な部分:これは断続的なエラーであり、テンプレートタグが原因であると思われます(ビューでもこのチェックを行いますが、エラーはありません)。
何か案は?
編集:完全なトレースバック
