如何检查(在模板中)用户是否属于组 [英] How to check (in template) whether user belongs to group
问题描述
如何检查用户是否属于某个组?
How to check in template whether user belongs to some group?
可以在视图
中生成模板
但是如果我想在 base.html
中检查这个扩展模板(它没有自己的视图功能)?
It is possible in a view
which is generating the template
but what if I want to check this in base.html
which is an extending template (it does not have it's own view function)?
我的所有模板都扩展了 base.html
,所以在每个视图
。
All of my templates extends base.html
so it is not good to check it in each view
.
base.html
包含上面的栏,其中应包含按钮,具体取决于哪个组
登录的用户是(客户,卖家)。
The base.html
contains upper bar, which should contain buttons depending on in which group
logged user is (Customers, Sellers).
在我的 base.html
中是:
{% if user.is_authenticated %}
这还不够因为我必须从客户
和 Sellers
中的用户执行不同的操作。
which is not enough because I have to act differently to users from Customers
and users from Sellers
.
所以我想要的是:
{% if user.in_group('Customers') %}
<p>Customer</p>
{% endif %}
{% if user.in_group('Sellers') %}
<p>Seller</p>
{% endif %}
推荐答案
自定义模板标签:
from django import template
from django.contrib.auth.models import Group
register = template.Library()
@register.filter(name='has_group')
def has_group(user, group_name):
group = Group.objects.get(name=group_name)
return group in user.groups.all()
在您的模板中:
{% if request.user|has_group:"mygroup" %}
<p>User belongs to my group
{% else %}
<p>User doesn't belong to mygroup</p>
{% endif %}
