Django - 使用模板标签和'with'？ [英] Django - use template tag and 'with'?

问题描述

我有一个自定义模板标签：

I have a custom template tag:

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，所以我可以正确复数：

and I'd like to do something like this, so I can pluralize properly:

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

但是， uploads_for_user leader 在此上下文中不起作用，因为'with'标签需要一个单一的值 - Django返回：

However, uploads_for_user leader doesn't work in this context, because the 'with' tag expects a single value - Django returns:

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

任何想法我可以如何解决这个问题？

Any idea how I can get round this?

推荐答案

您可以将其转换为过滤器：

You could turn it into a filter:

{% with user|uploads_for as upload_count %}
