我是Django初學者，如何從配置文件模型中獲取profile_pic，將其連接到FriendRequest模型中的“to_user”字段。我能夠通過以下方式在“to_user”字段中獲取用戶的名稱：{% for data in sent_friend_request %}{{ data.to_user.username }}{% endfor %}如何獲取每個用戶的profile_pic？class Profile(models.Model):    user = models.OneToOneField(settings.AUTH_USER_MODEL)    profile_pic = models.ImageField()class FriendRequest(models.Model):    to_user = models.ForeignKey(settings.AUTH_USER_MODEL)    from_user = models.ForeignKey(settings.AUTH_USER_MODEL)def following_view(request, username):     sent_friend_request = FriendRequest.objects.filter(from_user__username=username)context = {'sent_friend_request':sent_friend_request}{% if data.to_user.profile_pic %} <img src="{{ data.to_user.profile_pic }}">{% endif %}
