我有两个这样的模型:
class GuestStatus(models.Model):
guest_status = models.CharField(max_length=200)
arrangement = models.IntegerField(unique=True, help_text="Start from 1. Guest status will be arranged alphabetically.")
class Guest(models.Model):
user = models.ForeignKey(User)
full_name = models.CharField(max_length=250)
street_address = models.CharField(max_length=250, blank=True, null=True)
city = models.CharField(max_length=150, blank=True, null=True)
state = models.CharField(max_length=120, blank=True, null=True)
zip_code = models.CharField(max_length=15, blank=True, null=True)
status = models.ManyToManyField(GuestStatus, blank=True, null=True)
invitation_date = models.DateTimeField(blank=True, null=True)
我正在尝试在模板中检索数据:
#Views.py:
guests = Guest.objects.filter(user_id=request.user.id)
# Template:
{% for guest in guests %}
<tr>
<td width="5%"><input type="checkbox" value="{{ guest.id }}" name="guest_name" id="{{ forloop.counter }}" /></td>
<td><a href="/{{ guest.id }}/guest/">{{ guest.full_name }}</td>
<td>{{ guest.guests }}</td>
<td>{{ guest.children }}</td>
<td>{% for i in guest.gueststatus_set.all %}{{ i.status }}{% endfor %}</td>
</tr>
{% endfor %}
这不会给gueststatus
带来任何结果。怎么了?
答案 0 :(得分:6)
对于ManyToMany
,您无法获得_set
,请将您的查询更改为guest.status.all()
,同时使用{{i.guest_status}}
,因为GuestStatus
已guest_status
status
。
<td>{% for i in guest.status.all %}{{ i.status }}{% endfor %}</td>
