Django:想要将空白字段显示为空白，而不显示无 [英] Django: Want to display an empty field as blank rather displaying None

问题描述

我有一个名为client_details.html的模板，其中显示 user ， note 和 datetime .现在有时，客户可能没有用户，注释和日期时间的条目.如果这些字段为空，我的程序将显示 None .我不希望显示无".如果一个字段没有值，我不想看到任何值，例如尽可能将其保留为空白，而不显示无".

I have a template called client_details.html that displays user, note and datetime. Now sometimes, a client may not have an entry for user, note and datetime. What my program will do instead is display None if these fields are empty. I do not want the to display None. If a field has no value I don't want to see any value e.g. let it be blank if possible instead of displaying None.

views.py

@login_required
def get_client(request, client_id = 0):
    client = None
    try:
        client = models.Client.objects.get(pk = client_id)
    except:
        pass
    return render_to_response('client_details.html', {'client':client}, context_instance = RequestContext(request))

模板

{{client.datetime}}<br/> 
{{client.datetime.time}}<br/>  
{{client.user}}<br/>
{{client.note}}<br/>

推荐答案

您可以使用:

{% if client %} {{client.user}} {% else %}   {% endif %}

只需检查就足够了，因此，如果您愿意，您可能不希望其他用户阻止...

Checking with an if is enough, so you may not user else block if you want...
