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')
这很正常,请关注并取消关注
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%}
但是我想使用User对象获取Relationship status字段,以找出所有用户的状态为“已关注”或与经过身份验证的用户共有。我不想创建循环。就像上面的关注和取消关注一样,我内部是否有检查request.user的信息,就像我要检查状态是相互还是关注的。
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 %}
类关系(models.Model):from_user = models.ForeignKey(User,related_name ='from_user')to_user = models.ForeignKey(User,related_name ='to_user')status = models.CharField(...
尝试一下:我认为这可能对您有帮助,
{% 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 %}
