Python - 检查用户是否在团队中

Question

我有一个存储团队和成员的模型。我想检查请求的用户是否在这个团队中。我该怎么做？

型号

class TeamPlayer(models.Model):
    team = models.ForeignKey(Team, related_name='players', on_delete=models.CASCADE)
    player = models.OneToOneField(User, related_name='player', on_delete=models.CASCADE)
    approved = models.BooleanField(default=False)

模板

{% if request.user in object.players.all %}
      <a href="{% url 'teams:leave' pk=object.id %}" class="btn btn-warning">Leave</a>
{% else %}
      <a href="{% url 'teams:join' pk=object.id %}" class="btn btn-success">Join</a>
{% endif %}

View 就是简单的DetailView。

如果您想在模板中这样做，只需像这样使用 teamplayer_set:

{% if request.user in object.teamplayer_set.all %}
