class Relationship(models.Model):
    from_user = models.ForeignKey(User, related_name='from_user')
    to_user = models.ForeignKey(User, related_name='to_user')
    status = models.CharField(max_length=255, choices=RELATIONSHIP_STATUSES)

field = models.ManyToManyField('User', through=Relationship, symmetrical=False, related_name='related_to')
field.contribute_to_class(User, 'relationships')

这工作正常关注和取消关注

users = User.objects.all()
{%for u in users %}
    {% if not request.user in u.related_to.all %}
          <input type="submit" value="Follow"/>
    {% else %}
          <input type="submit" value="UnFollow"/>
    {% endif %}
{%endfor%}

但我想使用 User 对象获取关系状态字段，以找出所有用户的状态是关注或与经过身份验证的用户相互。我不想创建循环。就像上面的关注和取消关注一样，我在里面检查了 request.user ，就像我想检查状态是相互的还是关注的

users = User.objects.all()

{% for u in users %}
   // here I want to get the Relationship status field using the User object to find out the status of all user is Following or mutual with authenticated user
{% endfor %}

试试这个：我认为这可能会帮助你，

{% for u in users %}
    {% for relation in u.relationship_set.all %}
        from: {{ relation.from_user.username }}
        to: {{ relation.to_user.username }}
        status: {{ relation.get_status_display }}
    {% endfor %}
{% endfor %}

也尝试“from_user”或“to_user”而不是“relationship_set”

内部视图.py 

users = User.objects.all()
mutual = []
for me in members:
    try:
       Relationship.object.get(to_users=me, from_users=request.user,status='Mutual')
       mutual.append(True)
    except Relationship.DoesNotExist:
       mutual.append(False)

内部模板

{% if mutual == True %}
Mutual
{% endif %}

请提出任何更好的想法，因为上面的代码为每个用户运行查询。对许多查询
