django {％如果user.groups =='FC'％}不起作用 [英] django {% if user.groups == 'FC' %} doens't work

问题描述

我正在使用django建立一个网站.

I'm making a website using django.

{％，如果user.groups =='FC'％}在我的模板中不起作用.我有类似的组.

{% if user.groups == 'FC' %} doesn't work in my template.I have groups like that.

例如，如下所示，我的一个用户(用户名为"hong")属于"FC"组.

For example, one of my users(username is 'hong) belongs to 'FC' group as you see below.

但是

{% if user.groups == 'FC' %}
      <li><a href="{% url 'register' %}">register form</a></li>
      <li><a href="{% url 'mypage' %}">fc's my page</a></li>
{% else %}
 <li><a href="{% url 'PT_mypage' %}">fitness' my page</a></li>
{% endif %}

如果user.groups ==''不起作用.

if user.groups == ' ' doesn't work.

如何检查用户组?我必须按组区分用户.

How I check the users' group? I have to distinguish the users by groups.

推荐答案

您必须使用标签.在您的应用程序中，您可以创建一个目录，该目录名为: templatetags .

You have to use tags. In your application, you can create a directory which is named : templatetags.

然后，您必须在文件 user_tags.py 中创建一个文件，该文件将包含:

Then, you have to create inside a file user_tags.py which will contain :

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.filter(name=group_name)
    if group:
        group = group.first()
        return group in user.groups.all()
    else:
        return False

然后，在模板中，如果要指定零件，...

Then, in your template, if you want to specify part, ...

{% load user_tags %}
...
...
{% if request.user|has_group:"yourgroupe" %}
# part which will only accessible for users registered in `yourgroup` 
{% endif %} 

它在我的应用程序中可以与不同的组(管理员，用户，访问者，..)一起使用)

It works in my application with different groups (admin, users, visitors, ..) ;)
