Django - 使用模板标签和 'with' 吗？

Question

我有一个自定义模板标签:

def uploads_for_user(user):
    uploads = Uploads.objects.filter(uploaded_by=user, problem_upload=False)
    num_uploads = uploads.count()
    return num_uploads

我想做这样的事情，所以我可以正确地复数:

{% with uploads_for_user leader as upload_count %}
    {{ upload_count }} upload{{ upload_count|pluralize }}
{% endwith %}

然而， uploads_for_user leader在这种情况下不起作用，因为 'with' 标签需要一个值 - Django 返回:

TemplateSyntaxError at /upload/
u'with' expected format is 'value as name'

知道如何解决这个问题吗？

Answer 1

你可以把它变成一个过滤器:

{% with user|uploads_for as upload_count %}
